As one who participated in the long-drawn campaign of Guadalcanal, I cannot find more appropriate words to characterize that operation than those of my predecessor, General Vandegrift, in his special prefatory note.

To him, as to many thousands of other U.S. Marines, living and dead, our nation and our Corps owe gratitude for the readiness, discipline, and esprit which enabled the Fleet Marine Force to launch and win America's first offensive in World War II.

Commandant of the Marine Corps



THE GUADALCANAL CAMPAIGN, a monograph prepared by the Historical Division, Headquarters, United States Marine Corps, is the fifth of a series of operational monographs designed to present to both the student and the casual reader complete and factually accurate narratives of the major operations in which the Marine Corps participated during World War II. As a sufficient number of monographs are brought to completion, these in turn will be edited and condensed into a single operational history of the Marine Corps in World War II.

The preparation of this monograph has been attended by certain problems of a special nature. The campaign was the first great offensive of the war, and it was begun in the greatest urgency. The units engaged were not as fully indoctrinated with the necessity for submitting full and complete reports as were the participants in later operations. The art of combat photography, later developed to such magnificent degree, was ax yet in its infancy. The hectic nature of the first few weeks on Guadalcanal was such as to make difficult, if not impossible, anything that was not closely and unmistakably connected with the business at hand--fighting.

Full assistance and cooperation have been given by all of whom they were requested. Individuals and various Government agencies have lent their aid whenever they were asked for it. The Office of Naval History, Naval Records and Library, and the various activities of the Army Historical Division must be mentioned as having been particularly kind and helpful. Similar acknowledgment must be made to the Marine Corps Schools for cartographic assistance, and to the Photographic Section, Headquarters, U.S. Marine Corps, for help with pictorial matter. Photographs are U.S. Marine Corps, Navy, or Army official. Lieutenant Colonel Robert D. Heinl, Jr. of the Historical Division, participated extensively in the final editing of this work and supervised its cartographic planning. Captain Samuel E. Morison, USNR, and Commander James Shaw, his assistant, made many valuable suggestions and supplied much helpful material, while Mr. Walton L. Robinson was generous with the invaluable information he has collected concerning the Japanese naval order of battle. Mr. Robert Sherrod, historian of Marine air operations, rendered generous help in many phases, as did Captain Edna L. Smith, USMCR, his assistant.

Finally, thanks must be given those officers and men who, having participated in the actions described, willingly and helpfully gave of their store of knowledge for the sake of allowing an accurate narrative to be written. in all cases their assistance has been invaluable, and in all cases it was cheerfully give.

Special Prefatory Note


December 5, 1947

We struck at Guadalcanal to halt the advance of the Japanese. We did not know how strong he was, nor did we know his plans. We knew only that he was moving down the island chain and that he had to be stopped.

We were as well trained and as well armed as time and our peacetime experience allowed us to be. We needed combat to tell us how effective our training, our doctrines, and our weapons had been.

We tested them against the enemy, and we found that they worked. From that moment in 1942, the tide turned, and the Japanese never again advanced.

Chapter I: Prelude to the Offensive

The Guadalcanal Campaign, the first amphibious offensive operation to be launched by the United States in World War II, was undertaken by the United States Navy and Marine Corps in August, 1942, just eight months after the Japanese had struck their initial blow at Pearl Harbor. The objective of this campaign, which was set in motion on short notice with the most limited means, was the initial step in a program designed to safeguard our imperiled lines of communication to Australia and New Zealand, which were in turn vital to the success of future operations projected in the South and Southwest Pacific theaters.1

The Advance of the Japanese

Commencing with the advantages conferred upon them by surprise, the initiative, and carefully laid plans the Japanese swept through East Asia, the Indies, and much of Melanesia during the first six months of 1942. The milestones of their advance were Wake, Guam, Singapore, Bataan-Corregidor, and all the Netherlands East Indies. With the southward sweep of the seemingly irresistible advance, they seized first Rabaul, on 23 January 1942, and then Bougainville, in the Northern Solomons, two months later. In Rabaul they secured a prize of great strategic worth, for it served not only as a bastion for the great central position at Truk, but also as a point of departure for further offensives to the south.2 Bougainville, together with other subsidiary positions down the chain of the Solomons, was intended to be a key outwork to Rabaul and an intermediate station in their relentless thrust toward the all-important, slender U.S. line of supply and communications from the Hawaiian Islands to Australia and New Zealand.

At the tip-end of the enemy's line down the Solomons lay the British port of Tulagi and the then little-known island of Guadalcanal.3

Having meanwhile secured, unresisted, positions at Lae, Salamaua, and Finschafen on the northern coast of new Guinea, as well as stepping-stones at Choiseul, Vella Lavella, and the Treasury Islands, the Japanese seized Tulagi, with its superb harbor, on 4 May 1942.4

At this time, the British-Australian garrison at Tulagi consisted merely of a few riflemen of the Australian Imperial Force, some members of the Royal Australian Air Force,

a member of the Australian Naval Intelligence, the Resident Commissioner for the area, the civil staff, and a few planters and missionaries. All nonessential civilians had been evacuated. Among those who remained, however, were the coastwatchers, experienced and courageous men who had in most cases spent their lives in this area, and who now were prepared to retire in to the bush, where, the secret radio-transmitters, they could observe and report the Japanese movements, whether by land, sea, or air.

The Japanese descent on Tulagi was preceded by a heavy air raid on 1 May. The next day, a coastwatcher on Santa Isabel Island reported two enemy ships in Thousand Islands Bay, and it was thereupon decided to evacuate the area completely.5

The British Resident Commissioner and the Anglican bishop (The Right Reverend Walter Hubert Baddeley) removed to Malaita; other designated civilians proceeded to Savo and Guadalcanal to establish coastwatching stations. The military and naval personnel, with a few civilians, crossed to nearby Florida and thence to the southern tip of Guadalcanal and out of the area. The Reverend Henry De Klerk, Society of Mary, remained at his post, the mission of Tangarare, on the southern coast of Guadalcanal, and other priests and nuns of the same missionary order likewise refused to leave their posts.

The enemy landing was accomplished by a force from the 3d Kure Special Landing Force from the cruiser-minelayer Okinoshima, which flew the flag of Rear Admiral Kiyohide Shima. The force consisted of a machine gun company, two anti-tank gun platoons, and a number of laborers, all divided in two groups. That which landed on Tulagi was commanded by Lieutenant Juntaro

Maruyama, while the Gavutu detachment was led by Lieutenant (j.g.) Kakichi Yoshimoto.6

The enemy force went ashore without opposition and in accordance with plans based on aerial reconnaissance. Defensive positions were set up immediately. Base construction and improvement of existing facilities were initiated. Coastwatcher stations were established at Savo Island; and at Taivu, Marau Sound (on the southeastern tip), Cape Hunter (on the south coast near Tangarare), and Cape Esperance, all on Guadalcanal. This activity was under the personal supervision of Lieutenant Yoshimoto.7

No immediate steps were taken by the enemy to develop air fields, although the plains on Guadalcanal, 17 miles away to the southward, offered excellent terrain for the purpose. All initial effort was bent toward establishing harbor facilities and a seaplane base at Tulagi, and toward developing the coastwatcher system mentioned above. A full month passed before surveying parties and patrols were put ashore near the mouth of the Lunga River. Late in June the survey was completed, and early in July construction work was undertaken in earnest on the airstrip.

The only check received by the enemy to their almost machine-like occupation of Tulagi came on the very day of their landing.8 United States Navy carrier aircraft, operating from Yorktown, of Task Force 17 (Rear Admiral Frank Jack Fletcher, USN) caught the enemy amphibious shipping concentrated in Tulagi Harbor and attacked, sinking the destroyer Kikutsuki and several smaller craft, and damaging another destroyer, Yuzuki and the cruiser-minelayer, Okinoshima.9 (Okinoshima was sunk one week later

north of the Solomons, on 11 May, by the American submarine S-42.)10 A number of seaplanes likewise were destroyed by Fletcher's strike, and shore installations received heavy damage.11

Short of this local check, and of that received a few days later at the battle of the Coral Sea, which will be discussed briefly at a later point, the enemy was undisputed in possession of the Solomon Islands as far south as Guadalcanal. From this base it would be possible to strike at Northern Australia, New Guinea, and the New Hebrides; it would likewise be possible to protect the until now wide open left flank of forces operating against Northern New Guinea and the United States' lines of air and surface communication with New Caledonia and the Antipodes.12

U.S. Countermeasures

Shortly after the fall of Rabaul, when it became obvious that the enemy intended an expansion to the southeast from the newly conquered Southeast Asia area, plans to contain his advance began to be formulated. On 18 February, Admiral Ernest J. King, Commander in Chief, U.S. Fleet, wrote the Chief of Staff, U.S. Army, saying that he considered it necessary to occupy certain islands in the South and Southwest Pacific. For this purpose it would be necessary to have Army troops for garrison, and King requested Marshall's approval.13

In reply, General Marshall wanted to know why King considered such a course necessary, and asked whether he had thought of using Marines for the garrison task. He asked to be told what King's complete plans were, and closed by saying:

In general, it would seem to appear that our effort in the Southwest Pacific must for several reasons be limited to the strategic defensive for air and group troops.14

In reply, King was more specific. He stated flatly that bases must be established at Tonga and Espiritu Santo, and challenged the statement of policy contained in Marshall's letter by saying that the general scheme for the Pacific must be not only to protect the lines of communication but also to set up strong points whence offensives could be mounted against the enemy in the Solomon Islands area and in the Bismarck Archipelago. In stressing the need for an early offensive, he laid down certain principles which he considered indispensable.

In staging operations of the type which he envisaged, the amphibious forces involved must be replaced at once by garrison troops, in order that they might prepare for further operations. Instead of serving as garrison troops, Marine would best be employed in amphibious assaults and other advanced work.15

Occupation of certain strategically important islands began on 12 March. On that day Noumea, the capital of New Caledonia, was entered by a mixed force of U.S. Navy and Army, and the construction of a major air base at nearby Tontouta was immediately set afoot. On 29 March the 4th Defense Battalion (reinforced), Fleet Marine Force, landed at Port Vila, on the island of Efate, in the New Hebrides, to the north of New Caledonia, and less than two months later the island of Espiritu Santo was occupied and organized for defense by a combined force of Marines (from the 4th Defense Battalion and Marine Air Group 21), Naval Construction units, and Army personnel. At each of the latter two locations, naval and air base construction was begun with the maximum speed consistent with the slender means at hand.

While these initial counter-deployments of U.S. forces were in progress, the Japanese

had clashed with elements of the U.S. Pacific Fleet in the Battle of the Coral Sea, which took place on 7-8 May 1942, almost contemporaneously with the occupation of Tulagi. In this engagement, although it can hardly be said that a decisive U.S. victory had been gained, the enemy at least sustained a considerable check, losing a light carrier, the Shoho, together with 80 planes, and suffering severe damage to the big fleet carrier Shokaku.16 Moreover, a projected enemy invasion of South Papua was forestalled.

The United States forces in turn lost the USS Lexington, one of the familiar and much-loved aircraft carriers of the prewar Fleet. More important, however, than the actual losses of either side, was the fact that this engagement forced the Japanese to postpone - tentatively until July of 1942, as they now planned - the seaborne invasion of Port Moresby, on the south coast of New Guinea.17

Concurrently with these developments, Admiral King's plans for operations in the South Pacific began to be implemented. On 10 April he warned General Holcomb that the 1st Marine Division, currently attached to me Amphibious Force, Atlantic Fleet, would be sent to the South Pacific in May, probably to Wellington, N.Z.18 In reply, General Holcomb requested that the division be transferred to the Marine Corps prior to detachment for duty overseas.19

Two events of early June gave point and immediacy to what, up to the time, had been tentative planning. American air reconnaissance, confirming reports from coastwatchers stationed nearby, had observed that the Japanese were planning an air field on the Lunga Plains. This made it clear to Admiral King at least that the time had come to carry out that portion of Joint Chiefs of Staff's decision of 14 March which dealt with applying pressure to the enemy and containing him where possible.

At the time, another event far distant from the Southern Solomons brought about a decisive turn of circumstances in favor of the United States.

On 4 and 4 June, 1942, some 150 miles northwest of Midway Atoll, the combined attacks of carrier- and shore-based Navy and Marine air virtually annihilated the carrier-based air power of the Japanese Combined Fleet. Four enemy carriers - Kaga, Akagi, Soryu, and Hiryu - were sunk, as well as the heavy cruiser Mikuma, and with them went the flower of the Japanese Navy's carrier groups. More than 250 enemy aircraft had been destroyed, and, what was worse, the trained pilots, the teamwork, and the organization which go into the highly coordinated operations of a carrier air group, had likewise been wiped out. For the time being, the Japanese Navy was as much off balance - perhaps even more so - than the United States Pacific Fleet after Pearl Harbor.20

The advantage accruing to the United States forces in the Pacific as a result of the decisive victory did not escape the attention of the astute MacArthur. On 9 June Nimitz noted that the General suggested an immediate assault upon Rabaul, by now Headquarters of the enemy 8th Base Force. MacArthur said that, if he were given a division of troops well trained in amphibious assault techniques, and naval support to include two carriers, he would undertake the task himself.21 The suggestion

21. War Diary, CinCPac, June, 1942. NRL. MacArthur was not the only commander in the Pacific who was in favor of immediate action. A fortnight before, Nimitz had written, on 28 May, to the General suggesting a raid on Tulagi by the 1st Raider Battalion, a Marine Corps unit. MacArthur advised against the scheme on the basis of insufficient force, and Ghormley concurred. The idea was dropped. Actually, six battalions, including the same 1st Raiders, were employed in reducing the position.


was rejected by the Navy on the grounds that American carrier strength, notwithstanding a present imbalance in enemy forces, was not sufficient to justify risking two of these invaluable ships in an operation that would make necessary their maneuvering in a severely restricted area, exposed to constant danger from enemy land-based aircraft.22

Following the great success at Midway, the Joint Chiefs of Staff, both alarmed by the steady and rapid southward extension of Japanese power through the Solomons, and quickened by the momentary breathing-space b ought by our victory at Midway, undertook a reconsideration of basic U.S. strategy in the Pacific.

As in now well know, the fundamental strategic policy of the United States and Great Britain, as conceived at the outbreak of hostilities in 1941, had been to concentrate upon the defeat of Germany, with a definite second priority being accorded the effort against Japan.23 In line with this policy, only such means had been apportioned to the Pacific war as would, in the judgment of the strategic planners, enable us to contain the Japanese, almost on their own terms. With this end in view, it had likewise been decided that no land offensive would be mounted in the Pacific before the fall of 1942, and that earlier operations would be limited to those necessary to establish and maintain our lines of communication to the Antipodes and to set up a few advanced bases required either for containment of the enemy or as springboards for the offensives in prospect. As we have seen, deployment for these purposes had commenced well prior to the Battle of Midway.

Now, however, the threat by the Japanese to our line of communication--and indeed, the ominous possibility that our precariously situated advanced outposts in the New Hebrides might be swallowed up--impelled a re-examination of possible courses of action in the Pacific.

On 25 June, King sent out two communications. He advised Nimitz and the Commander, Southwest Pacific Force,24 that the Joint Chiefs of Staff had directed that an offensive be launched against the enemy forces in the Lower Solomons. Santa Cruz Island was to be seized and occupied, as were Tulagi and adjacent areas in the Solomons. Permanent occupation forces would be Army troops from Australia. The target date was about 1 August, and the operation was to be under the direction and control of CinCPac.25

On the same day, however, he addressed a memo to Marshall, in which he said that it was urgent that the United States seize the initiative. He pointed out that a golden opportunity had passed--ideally, the offensive should have been launched about 3 June, when the main currents of Japanese strength were running toward Midway and Alaska. He urged that Marshall give favorable attention to the plan for attacking the Japanese in the Solomons area.

Marshall's answer, sent out next day, indicates clearly that despite the fact that an offensive had been directed, there was still no complete meeting of the minds between him and his Navy opposite number.

This time it was the question of command that gave the General pause. He did not agree that the proposed operation should be under Navy command. He pointed out that the are involved lay wholly within the Southwest Pacific, and he suggested strongly that General MacArthur was the only officer available capable of exercising command. He pointed out further that "we should not be bound by lines drawn on a map" and added that to his mind it would be most unfortunate

24. Two days before, an interesting message had been sent Ghormley by Nimitz. Very early in the morning of 23 June, Nimitz gave his subordiante the tally of the Midway victory, and suggested that the carriers consequently made available for other employment might be used by Ghormley as support for an operation aimed at driving the Japanese out of the Solomon Island.

to bring in another commander at that time to carry out the operation.26

King stood fast. On the same day which saw General Vandegrift receiving first warning of the impending campaign from ComSoPac in Auckland, the Admiral sent a final uncompromising memo to Marshall. He said unequivocally that the operation must be under Nimitz, and that it could not be conducted in any other way. After the amphibious phase was over, then control would pass to MacArthur. The command setup must be made with a view toward success, said the Admiral, but the primary consideration was that the operation be begun at once. In answer to Marshall's plea that the area lay within MacArthur's bailiwick, he pointed out that all the forces involved would come, not from MacArthur, but from the South Pacific, and he included two prophetic statements. He expressed doubt that much aid at all could be got from the Southwest Pacific area (since the nearest bomber base in that area lay 975 miles from Tulagi) and said:

I think it is important that this [i.e. seizure of the initiative] be done even if no support of Army Forces in the South West Pacific is made available.27

In fact, Southwest Pacific air support during the assault was negligible, and no ground troop support was ever forthcoming from that area.

In the meantime, and in line with earlier plans for a more deliberate assumption of the offensive, a significant development had taken place in the command structure of the Pacific Ocean area. A huge geographic wedge, bounded on the north by the equator, on the west by 160º West Longitude, and extending indefinitely southward, had been designated the South Pacific Area. Vice Admiral Robert L. Ghormley, USN, had been selected to command it, under Nimitz.28

Upon arrival in Pearl Harbor, Ghormley found out that whereas he was to command the South Pacific Area and South Pacific Force, including all air, sea, and ground forces (save ground troops actually assigned the mission of defense of New Zealand) within the area, his powers hardly matched his responsibilities. Nimitz advised him that from time to time task forces would be sent on missions within his area. In such cases, Ghormley's degree of control consisted only of the ability to direct that such task force commanders carry out their assigned missions. Only in extraordinary circumstances would he exercise local control and initiative.29

There were three steps in e establishment of Ghormley's command. on 22 May he set up his command post aboard the USS Rigel in the Harbor at Auckland, N.Z., as Prospective Commander, South Pacific Area and South Pacific Force. On 10 June he moved ashore to the New Government Building in the city of Auckland, still as Prospective Commander. On 19 June, satisfied at last that he had established adequate communications, he assumed full title and command.30 He still anticipated a possible offensive in the fall.

On 25 June, he received dispatches telling him of an impending operation, to be mounted from his area and employ his forces. He was directed to begin planning at once with this in mind. The forces to be employed would be organized by CinCPac, and execution of the plan would be by directive from the Joint Chiefs of Staff. Two days later he was warned that Army participation in the operation, which had been assumed, might be delayed.31

Four days later, when General Vandegrift had been told of the plans and directed to make preparation, as will be described below, more definite information came to Ghormley

Probably more converant with the European situation than anyone else in the Navy, he was recalled to Washington, given an ominous mission and a hurried briefing, and sent on his way within a fortnight. He was warned by Admiral King that probably in the coming Fall an offensive would be begun from his area, but that it was impossible to give him proper tools for carrying out his mission. Ghomley ms.

from Nimitz. Ghormley was told that he would command the operation, and that the joint forces would be under command of Vice Admiral Frank Jack Fletcher, who would assume command when he reported with Task Force 11 at rendezvous prior to movement to the target area. one week later, on 4 July, he received the Joint Chiefs' detailed plan.

The Commander, South Pacific Area, was faced with the two-headed problem of mounting an offensive at an almost impossibly early date with a barely adequate force. A slight amelioration of the time problem was offered when the target date was set back one week (see below); the problem of adequacy of means remained until the operation was well under way.

The Joint Chiefs of Staff directive of 2 July, relayed by Nimitz to Ghormley late the same day, set out succinctly the military aims of the moment for the war against Japan in the South Pacific and Southwest Pacific areas. The ultimate aim was the seizure and reduction of New Britain, New Ireland, and New Guinea. The purpose was, as we have seen, the removal of a serious threat to the lines of communication between the United States and Australia and New Zealand.

The realization of the ultimate goal involved the accomplishment of three tasks. First, it would be necessary to seize and occupy Santa Cruz, Tulagi, and the adjacent areas. Second, the rest of the Solomon Islands would have to be occupied and defended, as would Lae and Salamaua and the vicinity. Third Rabaul and the surrounding territory would be taken.

The general considerations were that the Joint Chiefs would determine the forces, the timing, and the passage of command, that the date for undertaking Task 132 would be about 1 August, and that throughout all three tasks, tactical command of the amphibious forces would vest in the Naval Task Force Commander. For Task 1, CinCPac would designate the forces to be used, for Tasks 2 and 3, the selection would be left to General MacArthur. Effective on 1 August, the boundary of the South Pacific Area was to be moved one degree west, to 159º East Longitude. It was assumed that Ghormley would be the Task Force Commander for Task 1, "which he should lead in person in the operating area." Ghormley was directed to confer with MacArthur.33

The result of the conference, at which MacArthur and the Admiral found themselves in complete agreement, was that a dispatch was sent jointly by them to King and Marshall. In essence, the message urged strongly that the proposed operation be postponed until such time as American strength in the South and Southwest Pacific had been built up sufficiently - especially in the matter of air power - to provide adequate support for the assault.34

The Joint Chiefs of Staff replied to the effect that although all arguments presented by Ghormley and MacArthur were valid, it was imperative that the operation go forward. Additional shipborne aircraft and surface forces would be made available. Thirty-five heavy bombers, presently in Hawaii, would be supplied by the Army, which also planned to "take al the follow-up measures possible in support of the seizure and occupation of the Tulagi Area."35 The message also directed Ghormley to itemize to the Joint Chiefs additional forces essential to the success of the operation and not available to him.

Ghormley, in turn, replied that he considered the forces available--or to be made available in accordance with the Joint Chiefs' assurances - to be adequate for the immediate

34. Upon receipt of this plea, King wrote Marshall, noting that whereas three weeks before, MacArthur had wanted to move straight to Rabaul, he now objected to an assault upon a much less formidable target. He pointed out that if the Japanese were permitted to consolidate their holding at Tulagi, they would be in a position to harass the United States base at Efate and lines of communications.

task, provided that General MacArthur have sufficient means for interdicting hostile aircraft activities on New Britain, New Guinea, and the Northern Solomons. His reply contained the following prophetic words:

I desire to emphasize that the basic problem of this operation is the protection of surface ships against land based aircraft attack during the approach, the landing, and the unloading.36

General MacArthur, again seeing eye to eye with Ghormley, requested planes, and more planes for the purpose of supporting the operation.

And so, while King's reiteration of attack, size the initiative, and do it now was beginning to take on the throbbing insistence of a war drum, and while Marshall was temporizing in his replies to him, the plans for the offensive began to be implemented. On 10 July Admiral Nimitz sent Ghormley his operation order covering the proposed seizure of Tulagi and Guadalcanal. The operation was to bear the name WATCHTOWER.

U.S. Means Available

When Ghormley received his first warning order, on 25 June, the 1st Marine Division, Fleet Marine Force (or FMF, as usually abbreviated) under the command of Major General Alexander Archer Vandegrift, was in process of moving from the United States to Wellington, New Zealand. The advance echelon37 had arrived on 14 June, and the rear was at sea.

This division, which in fact constituted the major available Marine Corps unit in readiness for employment on short notice38 was itself understrength by about one-third, one of its rifle regiments, the 7th Marines (reinforced),39 having been temporarily detached on 21 March 1942 to become part of the 3d Marine Brigade, on duty in Samoa.

Other FMF units were deployed at this time to the maximum capacity of the Marine Corps throughout the Pacific, both within and outside Admiral Ghormley's area. American Samoa was defended by the 2d and 3d Provisional Marine Brigades, the 2d, 7th, and 8th Defense Battalions (of the Marine Corps) and the 1st Marine Raider Battalion. At Palmyra, Johnston, Midway, and the Hawaiian Islands other FMF troops, mainly defense battalions or aviation units, were likewise disposed to form a thin screen of defense for outlying Allied bases and lines of communication. Of a total strength of 142,613, the Marine Corps had 56,783 officers and men serving overseas at the time.

When decision to strike was reached, the 1st Marine Division was in process of moving from the United States to New Zealand, for what General Vandegrift thought was to be several months of training.40 The first echelon of the division had arrived at Wellington in organizationally-loaded ships and

37. Final Report, Phase I, p. 1, and Annex A to that document. The advance echelon consisted of the 5th Marines (reinforced), Division Headquarters, and certain division troops, and was embarked in the Elektra, Del Brazil, and Wakefield. The rear echelon, consisting of the 1st Marines (reinforced) and the rest of the division troops was on board the Lipscomb Lykes, Alcyone, Libra, Alchiba, Mizar, Ericcson, Elliot, and Barnett. The ships were not combat loaded.
38. The 2d Division was at Camp Elliott, California, being whipped into shape after losing many of its experienced officers and men to newly formed regiments. One of its rifle regiments, the 8th Marines (reinforced) was also in Samoa, having departed the United States in January, 1942. Another, the 6th Marines, had recently returned from seven months in Iceland.
39. The use of odd numbers for all components of the Division bears explanation here. There was a division on each coast--the 1st at New River, North Carolina, the 2d at Camp Elliott, near San Diego, California. Current practice made all components of the East Coast unit odd numbered, while the corresponding components of the West Coast division bore even numbers. This practice was in process of disappearing at the time--the 9th Marines, for example, was formed at Camp Elliott from a cadre supplied by the 2d Division and received its preliminary training with that division.
40. General Vandegrift was under the impression that his division would not be called upon for combat prior to the early part of 1943.

had begun to unload and go into camp. They second echelon was at sea, likewise in organizationally-loaded vessels, and was not expected to arrive until 11 July, less than three weeks before the target date.

To supplement the Marine Forces enroute to, or already on duty in the South Pacific, Army ground and service troops were not to be found at New Caledonia,41 the Fiji Islands (where they had been sent to replace a New Zealand Division withdrawn for defense of New Zealand), Tongatabu, and the New Hebrides. These forces, together with Army air units within the area, initially were controlled directly by Ghormley. On 1 July, however, CominCh informed him that Major General Millard Harmon, USA, was to be appointed to command of all Army forces in the South pacific Area, with the title of Commanding General, South Pacific Area. Harmon, in turn, would be under Ghormley's command and responsible directly to him.42 The appointment was made and Harmon began his duties late in July.

Within the naval structure of the Pacific Ocean Areas, Ghormley, as we have seen, occupied the position, under Admiral Nimitz, of a major subordinate of limited autonomy. Specifically, his powers were as follows:

1. Nimitz from time to time would order Task Force Commanders to report to Ghormley for duty, with missions already assigned.
2. Ghormley, in turn, would direct such commanders to carry out their assigned missions (as given them by Nimitz).
3. "The Commander, South Pacific Force would not interfere in the Task Force Commander's mission unless circumstances, presumably not known to the Commander-in-Chief, Pacific Fleet, indicated that specific measures were required to be performed by the Task Force Commander. The Commander, South Pacific Force would then direct the Task Force Commander to take such measures"43

The naval strength that could be called upon to operate in support of Ghormley's offensive was small in point of number of ships, albeit included in that number there was considerable power. Three aircraft carriers, with a strength of about 250 planes, were available, as were a number of light and heavy cruisers, two new battleships, and the requisite screening vessels and auxiliary craft. Transports and cargo vessels were at a premium, and would continue so for several months.

In air strength, an indispensable adjunct to modern amphibious operations, the picture was by no means as bright. In addition to the approximately 250 carrier aircraft mentioned above (available to him only under certain conditions), Ghormley could muster 166 Navy and Marine Corps planes (including two Marine Corps squadrons--VMF-212 and VMO-251), 95 Army planes, and 30 planes from the Royal New Zealand Air Force. This total of 291 aircraft was under the command of Rear Admiral John S. McCain, USN, whose title was Commander Aircraft South Pacific and who was under Ghormley's command.44

Taken all in all, therefore, Ghormley could rely on the services of a small, highly trained striking force of ground troops, consisting of less than one Marine division with its supporting organic units, surface forces of fluctuating and never overwhelming power (which nevertheless represented the maximum which Admiral Nimitz could spare) and an extremely scanty array of land based aircraft. He had no assurances of reserve ground troops for the coming operation (although plans were under way to release both the 7th and 8th Marines from their Samoan defense missions)45 and he had been advised that garrison forces would have to come from

the troops within his area who already were committed to base defense.46

The general structure organized to employ these resources against the Japanese was laid down in Nimitz' order to Ghormley of 9 July, and Ghormley's Operation Plan 1-42 of 17 July 1942.47

Ghormley, exercising strategic command, set up his organization in three main groups:

The Carrier Force (Task Force 61) commanded by Rear Admiral Leigh Noyes, was composed of elements of three task forces from Nimitz' area--11, 16, and 18. It would include three carriers - Saratoga, Enterprise, and Wasp - the fast new battleship North Carolina, five heavy cruisers, one so-called antiaircraft cruiser, and 16 destroyers.

The Amphibious Force (Task Force 62) commanded by Rear Admiral Richmond K. Turner, USN, included the FMF Landing Force,48 six heavy cruisers, two light cruisers, 15 destroyers, 13 attack transports, six attack cargo ships, four destroyer transports, and five minesweepers.

Shore-Based Aircraft (Task Force 63) under command of Rear Admiral J.S. McCain, USN (ComAirSoPac) included all aircraft in the area save only carrier-based naval planes.

Complicating the foregoing symmetrical structure was the presence of Vice Admiral Fletcher as tactical commander of the joint attack and support forces. (See footnote on Nimitz' Operation Order No. 34-42 above. Fletcher was already familiar to the Marines as a result of his role in the attempt to relieve Wake Island.49

Ghormley also announced that there would be a rehearsal in the Fiji area prior to departure for the assault and directed that all task force commanders arrange to hold a conference near the rehearsal area. He himself would move to Noumea about 1 August in order to comply with his orders to exercise strategic command within the operating area.50

By this time the planning and the resultant orders had taken final form. The target had been selected, the forces organized which were to strike at the target. The Navy had leeway, thanks to the 2 July directive which, by moving the South Pacific boundary one degree west, had made it possible for Ghormley's forces to operate without poaching in the territory of the Southwest Pacific.

Only one detail remained unsettled. The target date, set up first in the warning orders Ghormley received on 24 June and reiterated in the 2 July directive, was still 1 August and impossibly close. Vandegrift pointed out to Ghormley that the late arrival of his second echelon, taken in conjunction with an unforeseen stretch of bad weather, had so complicated his loading problem as to make it impossible to meet the date set. Ghormley agreed, suggesting that at least a week additional time would be needed. Nimitz concurred, passing along the request to King. King agreed to set back the date to 7 August, and Ghormley was so notified, with the stipulation that this was the latest date permissible and that every effort should be made to advance it if possible.51 The new date was incorporated in Ghormley's Operations Order 1-42, of 17 July 1942, in which the foregoing task force structure was set up and which contained the additional admonition that all


46. Admiral King's effort to secure quick release for the assault troops was not successful. The Army's commitments to the European Theater were such that no units were vailable for such missions. Initially assured that air support and air replacements would be available, King was warned by Lieutenant General Joseph C. McNarney, USA, acting Chief of Staff, on 27 July that commitments in other areas would not permit further air reinforcements for the South Pacific--a dictum which King protested strongly in a memo to Marshall on 1 August.

ships of the joint force should fuel to capacity at the conclusion of the rehearsal.

Inasmuch as Admiral Turner's amphibious force (Task Force 62) was the one which included the Landing Force and which would carry out the actual assault and landings on Guadalcanal and Tulagi, the internal structure of that command requires our attention.

Like all such task forces it was subdivided into internal components, each known as a task group. One of these was that commanded by General Vandegrift, while others included fire-support ships, transports, minesweepers, and such other units as are required to carry out the naval phase of a landing operation. Within General Vandegrift's command there existed two principal subdivision, to which appropriate transport task-groups of Admiral Turner's force corresponded--namely, the units assigned, respectively, for the Tulagi and the Guadalcanal assaults. These will be described in detail at a later point.

Accumulation of Intelligence

From the intelligence point of view, the Guadalcanal-Tulagi landings can hardly be described as more than a stab in the dark. When General Vandegrift received his initial warning-order on 26 June 1942, neither his staff nor the local New Zealand authorities had more than the most general and sketchy knowledge of the objective area,52 or the enemy's strength and disposition therein. What was more, less than a month was available between the announcement of the mission and the scheduled date of mounting out, 22 July. During the four weeks at hand, every effort had to be, and was, bent toward piercing the fog of blank ignorance and some misinformation which enshrouded Guadalcanal and Tulagi.

As is the case with most tropical backwaters, the charting and hydrographic information was scanty and out of date. Recourse thus was automatically directed toward individuals with on-the-spot experience who could be discovered either in New Zealand or Australia. The accumulation, evaluation, and dissemination of this material fell to Lieutenant Colonel Frank B. Goettge, Intelligence Officer of the 1st Marine Division, Colonel Goettge's first step was to locate such persons, mainly traders, planters, ship-masters, and a few miners, who had visited or lived at Guadalcanal or Tulagi. A number of possible likely sources, he soon found, were now living in Australia, and, while his subordinates set about tabulating the formal data available, Goettge set out for Australia on 2 July, returning to New Zealand on the 13th.53

Long after the conclusion of the campaign, in the late winter of 1943, it was learned that Colonel Goettge's efforts deserved a better success than they had enjoyed. During his hurried trip to Australia, he arranged with the Southwest Pacific Area for maps to be made from a strip of aerial photographs and to be delivered prior to the sortie of the 1st Marine Division. These were never delivered, and the incident apparently was forgotten by the 1st Division staff.

After the arrival of the Division in Australia, however, Lieutenant Colonel Edmund J. Buckley, who succeeded Colonel Goettge as D-2, was asked by an Army officer whether the maps he had prepared had been useful. Further inquiry by Buckley brought to light the information that a special flight had been made, photographs taken, and a map made and sent to New Zealand. Nothing further was done in the matter at the time.

During the summer of 1948 a letter was sent to Dr. John Miller, an Army historian and former Marine, by Colonel E.F. Kumpe, of the Corps of Engineers. Pertinent extracts are quoted herewith through the courtesy of Dr. Miller:

Colonel E.J. Buckley, USMC, the G-2 of the 1st Marine Division following the death of Colonel Goettge is quite correct in his recollection. I was at that time the map chief for SWPA and also the Commanding Officer of the 648th Engineer Topographic

Battalion which had recently arrived at Melbourne. The red rush job at that time was the preparation of photomaps for Guadalcanal. The photography was flown by Colonel Karl L. Polifka of the Air Force, now in Quarters 200 at Maxwell Field, and consisted of two strip along the north shore of the island. The following information is not a tale of woe, but a very distressing account of what eventuated at that time. The photographs were printed in the north, and the prints and negatives assigned A-1 priority for shipment to GHQ and subsequently to the map plant. They were diverted for approximately 10 days due to a whim of the Transportation Officer at Townsville, and subsequently delivered to the map plant. Unfortunately, I do not recall the specific date, but it was in advance of the operation.

At the base map plant three sets of duplicate prints were prepared and transmitted to Auckland, and a duplicate set of negatives was also prepared by hand. An additional set of prints was assembled in the form of a mosaic on a concrete floor as equipment had not yet been received and was compiled for civilian reproduction in Melbourne. Manuscript copies of these photo-maps were transmitted in three separate shipments to Auckland with request for bulk distribution.

No bulk distribution request was received and it was a matter of considerable surprise to discover that neither the photograph nor the photo-maps had been available to the 1st Marine Division. An informal investigation after the operation brought out the information that the maps had been lost in the tremendous pile of boxes incident to the organizing of the base establishment of South Pacific (SOPAC). Colonel Buckley stated on subsequent occasions that some oblique photographs captured from the Japanese were the only source of maps during the opening phase of the operation. On the second operation of the 1st Marine Division at Cape Gloucester, New Britain, they received the best maps then available for any operation in the western Pacific, both in the form of topographic maps and with a back printing of the photo-maps, and were duly grateful.

The story does not sound too good in its reflection on the coordination between theaters. However, in this particular case, every effort was made from the western Pacific to send forward all they had to meet the operational dates.

This unfortunate series of events was unknown and unsuspected at the time. All that was known was that a search carried out with great intensity failed almost utterly to produce usable and dependable maps and charts. The Marines were reduced to using what they could gather of the personal knowledge of former residents or travelers of the area.

The fruits of Colonel Goettge's inquiries may be summarized for the benefit of the reader, with appropriate corrections in terms of a general description of the area which would soon become so familiar to members of the 1st and 2d Marine Divisions.

Tulagi and Guadalcanal, the targets of the operation, are dissimilar physically. Tulagi is a relatively small island lying within an indentation of the coast of Florida, the largest island of the Nggela Group. It is a hilly mass, heavily wooded and with little level ground. Its chief importance lies in that it guards an excellent small harbor and is the seat of government of the British Solomon Islands.

To the east of its southern extremity lie two small, hilly islands, Gavutu and Tanambogo. A causeway connects the pair, of which Gavutu is the larger. They are by far the most important of Tulagi's peripheral islands.

Guadalcanal, on the other hand is a land mass about 90 miles in length whose long axis lies in a southeasterly-northwesterly direction. It presents a varied terrain, with plains, foothills, and mountains and with a range of vegetation that runs from grassy plains to true rainforest and jungle.

The mountain backbone of the island is parallel to the long axis. The slope to the southwest is abrupt, and there is little extensive plains country on that side of the


island. On the opposite coast, however, from the mouth of the Lunga River to the east, there is a wide belt of plains, cut by rivers and covered with jungles interspersed with broad patches of grass lands. These well watered plains are ideal for the development of copra plantations, for which purpose they have been used since the beginning of the century. Rainfall is extremely heavy, and changes in season are marked only by changes in intensity of precipitation. This, together with an average temperature in the high 80's, results in a humid, unhealthy climate. Malaria, dengue, and other fevers, as well as fungus infections, afflict the population.

Rivers are numerous, and from the military point of view may be divided arbitrarily in two classes. The first of these is the long, swift, relatively shallow river that may be forded at numerous points. Generally deep for a short distance up from its mouth, it presents few problems in the matter of crossing. Examples of this type are the Tenaru, the Lunga, and the Balesuna.

The second type is that of the slow and deep lagoon. Such streams are sometimes of inconsiderable length, as in the case of the Alligator Creek, and again are merely the coastal extremities of rivers of considerable size, as in e case of the Matanikau. This type, because of its depth and the precipitous nature of its banks, was an admirable defensive aid.

Beaches on both Tulagi and Guadalcanal were frequently treacherous because of the broad coral formations. In the vicinity of the Lunga, however, and in some spots farther to the northwest, it was possible to bring large craft almost to the shoreline because of the close-in steep-to.

Although this accumulation of data afforded much enlightenment beyond the little previously known, it included corresponding minor misinformation and many aggravating gaps, for detailed information in a form suitable for military operations was mainly lacking.

In spite of the number of years which had elapsed since initiation of the systematic economic development of the islands by the British, not a single accurate or complete map of Guadalcanal or Tulagi existed in the summer of 1942. The hydrographic charts, containing just sufficient data to enable trading schooners to keep from grounding, were little better, although these did essay to locate a few outstanding terrain features of some use for making a landfall or conducting forms of triangulation. In one case, in fact, Mount Austen (Mambulo was its native name) was assigned as an immediate objective, only to have the discovery made--after the Guadalcanal landing--that, instead of being but a few hundred yards away from the beaches, it actually lay several miles distant, across almost impassable jungle.54

The second and more profitable source of up-to-date information would of course be aerial photographs, but the paucity of long-range aircraft and suitably located bases, together with the short notice upon which planning had been launched, combined to restrict availability of aerial photos in the quantity and quality normally considered necessary for Fleet Marine Force landing operations.

Perhaps the most useful photographic sortie carried out prior to the Guadalcanal-Tulagi landings (except for the fruitless effort described previously) was that undertaken by an Army B-17 aircraft in which Lieutenant Colonel Merrill B. Twining (assistant operations officer (D-3) of the 1st Marine Division) and Major William B. McKean (member of the staff of Transport Squadron 26) conducted a personal reconnaissance of the landing areas. This flight took off from and returned to Port Moresby, New Guinea, on 17 July and was, in fact,


54. This was the so-called "Grassy Knoll" assigned to the 1st Marines. Long-time Guadalcanal residents described it as lying virtually within the perimeter area ultimately occupied and defended by General Vandegrift, whereas its true location was six miles to the southwest. This discrepancy, unexplained for years, has given much cause for speculation to historians of the Guadalcanal campaign, some of whom have raised the question whether Mount Austen was really the "Grassy Knoll" which Goettge's informants had in mind. This school of thought suggests that the only feature which could possibly fall within the described limits would have been the high ground later to become known as Edson's Ridge.

the first occasion during the war upon which Guadalcanal was sighted by U.S. Marines. The route followed made landfall in the vicinity of Cape Esperance, then proceeded to Tulagi Bay (where float-equipped Zero fighters could be seen preparing to take off on intercept), and then swung on a return leg along the north coast of Guadalcanal from Aola Bay westward toward the intended beachhead. Photostrips were taken all the way. Just as the bomber approached Lunga Point, however, the critical point of the reconnaissance and the area in which the Japanese were reportedly developing the Guadalcanal air-strip, the Zero fighters, which had now gained altitude, swarmed down. In the resultant melee, photography was of course impossible, and visual observation became largely valueless. Under the circumstances, therefore, and because the "turn-back" point had now been well passed, the reconnaissance could not be retraced. Thus neither Twining nor McKean could obtain positive information as to me progress of the Japanese in completing their field although they could ultimately reassure General Vandegrift as to the evident suitability of the Lunga beaches for landing. The return trip to Port Moresby was rendered successful by Major McKean's supervision of the somewhat haphazard navigation, on the basis of his Naval Academy training of years gone by.55

The coastal map of Guadalcanal finally adopted as official by the 1st Marine Division (and employed, with such corrections as could later be developed, throughout the entire campaign) was traced from an aerial strip-map obtained by Colonel Goettge on his mission to Australia, and, while reasonably accurate as to general outline, contained no usable indications of ground-forms or elevations. The Goettge map--a section of which is reproduced in this monograph as an indication of the crudeness of the topographic material available--was distributed to units of the division prior to departure from Wellington. This was supplemented by aerial photos of Tulagi, Gavutu, and Tanambogo Islands, and these constituted, altogether, the sum of what the 1st Marine Division was to know of Tulagi and Guadalcanal prior to the landings.56

Of the enemy's strength, dispositions and activities, it was known to the U.S. planners--largely from coastwatcher reports57--that the Japanese forces had established their headquarters in the former British governmental seat at Tulagi, that they had occupied and installed defensive positions on nearby Gavutu and Tanambogo, and that their construction

forces were busily at work across the Sealark Channel on the Guadalcanal airfield project. We have also seen that coastwatching stations had been set up on Florida, Malaita, and Guadalcanal.

Estimates of enemy strength were by no means as definite or convincing as were the factual accounts of the defenses. Various intelligence estimates, prepared during July, gave figures as high as 8,400, while Admiral Turner's Operation Plan A3-42, issued at the rehearsals at Koro Island on 30 July, gave it as the Admiral's opinion that 1850 enemy would be found on Tulagi and Gavutu-Tanambogo,


and 5275 on Guadalcanal. Both figures were high. A count of enemy dead in the Tulagi and Gavutu area placed the number of defenders at about 1500 (including 600 laborers) while a study of positions, interrogation of prisoners, and translation of enemy documents on Guadalcanal proper indicated that about 2230 troops and laborers had been in the Lunga area at the time of the Marines' landing.58

Close and determined combat was anticipated with these forces; what the future held in the way of counterblows, the 1st Marine Division had no way of foreseeing.59

Planning and Mounting Out

Tactically speaking, the task assigned the 1st Marine Division was dual in character, not only because of the considerable physical separation between its two initial objectives, that is, Guadalcanal and Tulagi, but because hard fighting was expected during or immediately after the latter landing. On the other hand, it was hoped that the former beachhead could be secured without instantaneous enemy reaction. This duality had, as we have seen, shaped General Vandegrift's task-organization into two landing forces; Group X-Ray (Guadalcanal) and Group Yoke (Tulagi). It likewise guided the Marine commander in his assigned of units to these two groups.

To the Tulagi group--commanded by Brigadier General William H. Rupertus, assistant division commander to General Vandegrift--the latter assigned the 1st Marine Raider Battalion (Lieutenant Colonel Merritt

59. Nimitz was preoccupied with this very problem. On 17 July he wrote King saying that it would be unsafe to assume that the enemy would not attempt to retake the area to be attacked, and that if insufficient forces were assigned, the Marines might not be able to hold on. Dispatch, CinCPac to CominCh, 17 July 1942. NRL.


A. Edson); the 1st Parachute Battalion (Major Robert H. Williams); and the 2d Battalion, 5th Marines (Lieutenant Colonel Harold E. Rosecrans). These were then considered to be the best-trained units, and therefore more suitable for the sharp work ahead.60

The Guadalcanal group, under General Vandegrift's personal leadership, would comprise the other two combat groups (as they were then styled) within the 1st Marine Division,61 plus the balance of the division special and service troops.

The northern scheme of maneuver, that on Tulagi, called for a landing on the south shore by the 1st Raider Battalion and 2d Battalion, 5th Marines, in column in that order, the attack then wheeling right (east) and moving down the long axis of the island. This would be followed by further landings by the Parachute Battalion on Gavutu and Tanambogo, plus a mop-up sweep by a Battalion (less one company) along Florida Island's coastline fronting Tulagi Bay.

The scheme on Guadalcanal envisaged landing the 5th Marines (less 2d Bn) across a beach somewhat removed to the eastward from whatever defended beaches or other defenses which the Japanese might have set up in the Lunga delta. This unit, landing on the right half of the beach with two battalions abreast, was to be followed by the 1st Marines in column of battalions. The units thus landed would therefore be assured no more than minor resistance at worst, plus the subsequent opportunity of assembling and forming for an overland attack to the west from an established beachhead. These schemes of maneuver were embodied in 1st Marine Division Operation Order 7-42, issued on 20 July at Wellington.62

In the attack on an area supposed, altogether, to be defended by more than 5,000 enemy, it will be realized that a division less one-third of its strength (i.e., the 7th Marines, reinforced) would have little if any margin in reserve. To remedy this hazard, Admiral King proposed, on 27 June, that the 2d Marines63 (reinforced), including its supporting light artillery battalion (3d Battalion, 10th Marines) and normal reinforcing elements, be ordered from San Diego, combat-loaded, to serve as landing force reserve.64

While the foregoing operational plans were in process of preparation, and while the accumulation and collation of intelligence progressed as best it could, the Guadalcanal landing force found itself confronted by a logistic task of monumental proportions. This was the job of completely unloading its original shipping; sorting and reloading its equipment and supplies; and accomplishing all this with troop labor under an intolerable pressure of time.

The reason for this massive reshuffle was that, as originally mounted out from the United States, the 1st Marine Division's shipping had been organizationally loaded, that is, equipment and supplies had been stowed aboard ship to take maximum advantage of hold-space, rather than in the uneconomical but necessary method known as combat-loading, whereby items are placed so as to be ready for unloading in accordance with the priority of their necessity in an assault landing. Inasmuch as shipping was scanty and overburdened, and, as originally planned, the 1st Division would not be employed in


60. Final Report, Phase I, p. 4.
61. At this time, the standard phrase "regimental combat team" (RCT) had not come into uniform use. What we would now style an RCT was what Guadalcanal Marines labelled a combat group, that is, a rifle regiment with its direct-support artillery battalion, engineers, signal, medical, and other combined supporting elements. Within the so-called combat groups, similar battalion-sized aggregations were designated combat teams. This usage will be followed throughout this monograph.
62. This order did not reach the 1st Raider Battalion and the 2d Marines until these units joined the main force in the rehearsal area on 27 July.
63. This unit was to be employed to carry out projected landings at Ndeni, in the Santa Cruz Islands. Needless to say, these were never carried out, although occupation plans for Ndeni, always involving Marine forces, continue to appear in Admiral Turner's records until October, 1942.

combat immediately, no reason could have justified combat-loading at the time of the force's movement to New Zealand from the United States.65 Combat loading moreover, would have been made difficult by the fact that most of the vessels used were passenger ships and not specially equipped attack transports.66

Almost overnight, however, while the Marines were still enroute, the situation, as we have seen, had changed. An assault operation was now in immediate prospect, and, as a necessary concomitant, it would be essential that the equipment and supplies of the Marine units reached Guadalcanal and Tulagi combat-loaded. Thus, as soon as the troops could be disembarked at New Zealand, the onerous task of unloading, rearranging, and re-loading had to be set on foot and had to be completed at all cost prior to the date set for departure.

Aotea Quay, at Wellington, was the scene of this operation. It was inadequate in all ways save that it could accommodate five ships at a time. Labor difficulties with the highly unionized stevedores--it was not possible to provide the incentive of pointing out that the ships and men in them were about to go into action--resulted in the entire unloading and re-loading task being undertaken and carried through the Marines. Dock-side equipment was meager, and there was no shelter. Carton-packaged foodstuffs and other supplies deteriorated rapidly in the persistent cold windy rain of a "southerly," as did the morale of the men.67

The re-loading and reembarking of Combat Group A (5th Marines, reinforced) was accomplished smoothly, uncomplicated by the necessity for literally unloading and reloading at the same time which plagued the operations of the rear echelon. The group was embarked beginning 2 July and remained on board its transports to await the arrival of the rear echelon.68

The logistic problem facing the rear echelon was much more sever and complicated. Arriving on 11 July, this group was faced with the necessity of completely emptying and reloading its ships on a dock, to repeat, that was lacking in specialized equipment and in shelter for material that was being sorted. The task, moreover, had to be completed by 22 July.

The problem was solved by what must be regarded as heroic measures. The troops were not disembarked, save those who were to remain


65. It must not be thought, however, that the importance of combat loading was not fully realized. The following extract from a letter of R.K. Turner (then Assistant Chief of Staff (Plans) under Admiral Stark) to the Commander in Chief, United States Fleet, clearly demonstrates this point.
"It is also recommended that definite decision be made to send to New Zealand the 1st Marine Division, one Marine Defense Battalion, eight combat loaded transports and 3 combat loaded cargo vessels." This letter, having for its subject Command Relations for Pacific Ocean Area, bears no date, but from its place in archives it appears to have been written about 1 April 1942--a time when, of course, there were no plans for specific, immediate offensive.

in New Zealand as rear echelon personnel. All others, who already had been in cramped quarters during the long trip across the Pacific, were put to work in eight hour shifts, and work proceeded around the clock. Parties of 300 men were assigned to each ship.69

During the process of mounting out, certain modifications of the logistic plan had become necessary. As finally loaded, the marine force was carrying 60 days supplies, 10 units of fire for all weapons, the minimum individual baggage, ". . . actually required to live and fight," and less than half the organic motor transportation authorized for the Division.70

Regardless of the difficulties, however, the force sailed as scheduled at 0900 on 22 July, under escort of cruisers of Task Force 62 under command of Admiral Turner.71 General Vandegrift, despite his request for a vessel better suited in communications and accommodations had been directed to embark his command post on board the USS McCawley.

Rehearsals and Movement to the Objective

In accordance with orders received from Nimitz on 1 July72 Ghormley had directed that all forces involved in the assault make rendezvous at a position south of Fiji, out of sight of land so that there would be no chance of observation by enemy agents and no chance that an inadvertent tip-off would be made by friendly observers.73 At that point there would be a conference between the commanding officers of all units involved, who had not as yet been able to discuss in person the various aspects of the coming observation.

The components of the assault force were converging upon the rendezvous point from many directions. The 2d Marines (reinforced), embarked in the Crescent City, President Adams, President Hayes, President Jackson, and Alhena, had sailed from San Diego on 1 July, under escort of the carrier Wasp and a destroyer screen. The regiment was combat loaded.74 The 1st Raider Battalion, in the four destroyer transports of Transport Division 12, had been picked up at Noumea and likewise was approaching the area. The 3d Defense Battalion, on board the USS Betelgeuse and Zeilin, was en route from Pearl Harbor, where it had been stationed since the outbreak of war, and was destined to meet the remainder of the force on 2 August. The Carrier Force, built around Saratoga and Enterprise, with Fletcher wearing his flag in the former, likewise was on its way from Pearl Harbor.

Rendezvous was effected as planned, at 1400 on 26 July, at a point 367 miles south of Fiji. The planned conference was held at once on board Saratoga, with all interested commanders attending save Ghormley, who was prevented by pressure of business. He was represented by his Chief of Staff, Rear Admiral Daniel J. Callaghan, and his Communications Officer, Lieutenant Commander L.M. LeHardy.


69. The passage from the United States to New Zealand had been particulary trying for the officers and men on board the Ericsson, a commercial ship under charter. Lack of proper food, and use of oil substitutes for shortening, resulted in loss of weight as high as 23 pounds per man. Two meals only were served during the greater part of the passage, and one of these often consisted of soup, or soup and bread. Medical officers estimated the daily calory content of meals as less then 1500. It bears mention that ship's personnel enjoyed a full and well balanced diet during the same period.

During the conference, several ominous points were brought out with painful clarity. We have seen that between King and Marshall there had never been a complete agreement and understanding. It became immediately apparent during the meeting on Saratoga that this condition existed even within the structure of the task force that had as its mission the carrying out of King's bold plans.

General Vandegrift learned, for the first time, that he had been wrong in assuming that he would have adequate air and surface support for the completion of the landing. His plans had been based upon such an assumption--that there would be enough time to disembark all forces and put ashore all supplies. His concurrent assumption was logical--that air support would be vouchsafed for the transports and the cargo vessels for as long as they might find it necessary to remain, up to four days after the landing.

He had never thought that his division was to be used in what, from Fletcher's point of view, was a hit and run raid. He was put right immediately on that point--the Commander of Task Force 61 planned exactly that type of operation. Callaghan reported to Ghormley that Fletcher considered it feasible to unload all transports during the first day and have them out of the area by nightfall. To unload the cargo vessels might take three or four days. Task Force 61, however, would have to be withdrawn within two days after D-day. It was obvious to Vandegrift, although it was not brought out explicitly, that his forces would thereupon be wide open targets for all the land-based enemy planes within striking distance of the island until such time as the airfield could be completed and planes ferried in to it.

To add to his worries, it seemed more than likely that the newly arrived 2d Marines (reinforced) would not be available to him as a reserve. They were to be used for the occupation of Ndeni, and Turner planned to depart the Tulagi area with them during the evening of D-day. Protests by Colonel DeWitt Peck, that a battalion would be sufficient for the Ndeni mission, were disregarded--the exposed position of Ndeni to thrusts from the Gilbert Islands area made it necessary that a strong force be used for the occupation. A rough draft of the plan for the occupation was presented--Callaghan thought it very sketchy.75

Callaghan also noted that there was confusion in the minds of everyone regarding details of carrier-based air support during the landing, and that the lack of time for proper planning was deplored. Fletcher assured him that any change in his tactical plans desired by Ghormley would be effected at once, and Callaghan gave it as his opinion that Ghormley would not hesitate to do so, although the imposition of radio silence would make it difficult for ComSoPac to keep abreast of the situation. There were insufficient copies of Fletcher's orders and plans, and Ghormley did not see them until some time in September, a month after the operation had begun,76 although Fletcher promised to land them at Suva, Fiji, on 31 July, at the conclusion of the rehearsal.

A final point of interest is that immediately before the rehearsals, Major Manly L. Curry, then commanding the 3d Battalion, 10th Marines, was called upon to give a lecture to the assembled gunnery officers of the Fire Support Group of the Amphibious Force. His subject was naval gunfire support, and his observation, based upon the fact that there were no dissensions or questioning of his remarks, was that the subject was new to many of his hearers.77

Rehearsals of the landings were held between 28 and 30 July. General Vandegrift's opinion was that they resulted only in a waste of time and effort78 - "A complete bust," he subsequently observed.79 Necessity for conserving landing craft made it impossible to conduct the practice landings in a realistic way, although the men involved were given

additional training in debarkation.80 Attack force ships also were able to practice the type of gunfire support they would be called upon to render.

On 31 July, as night was falling, the ships weighed anchor and departed from Koro, the Carrier Task Force proceeding north and west, while the transports and their screen plodded steadily toward the Solomons. Almost 19,000 Marines were embarked in the 19 transports and four destroyer-transports.81

All circumstances favored the advancing convoy, In the words of the Final Action Report:

Weather conditions during the final two days of the approach were extremely favorable. The sky was generally overcast with low ceiling and intermittent rain squalls. There were no signs of hostile reconnaissance aircraft of submarines, and nothing indicated that our approach had been observed.

Fortune smiled upon the Marines more benignly that they realized. Enemy patrol planes were grounded at Rabaul on 5 and 6 August because of bad weather.82

Later in the campaign, it was found that actually there had been some idea on the part of the Japanese that there would be and attack on their positions sometime in July or August,83 but it is not clear, from the document whence this information was taken by our translators, whether this was merely a shrewd guess on the party of the enemy, or whether it was in fact based on definite information.

If the enemy had definite information about the impending strike, it is hard to understand his careless security, for the task force reached the objective area apparently without having been observed in any way, and during the last three days of the approach it was within range of aerial observation.

The course chosen took the convoy generally west from Fiji and well to the south of the Solomons chain.84 The course gradually shifted to the northward, and the night of 6-7 August found the entire group of ships, due west of the western extremity of Guadalcanal.

Task Force 62, commanded by Rear Admiral R.K. Turner, was divided into two Transport Groups, Transport Group X-ray (62.1) commanded by Captain Reifsnider, with the Guadalcanal forces embarked, consisted of four subgroups, as follows:

Transdiv A: Fuller, American Legion, Bellatrix.
Transdiv B: McCawley, Barnett, Elliot, Libra.
Transdiv C: Hunter Liggett, Alchiba, Fomalhaut, Betelgeuse.
Transdiv D: Crescent City, President Hayes, President Adams, Alhena.

Transport Group Yoke (62.2) commanded by Captain Ashe and carrying the assault troops for the Tulagi landing, consisted of the following subgroups:

Transdiv E: Neville,, Zeilin, Heywood, President Jackson.
Transdiv 12: Calhoun, Gregory, Little, McKean (the destroyer transport group)85


80. General Vandegrift noted at the time that the precious landing craft were not in the best of condition in any event--12 of them were inoperative on one ship alone. Letter, General Vandegrift to Commandant Marine Corps, 4 February1949.
81. A total and seemingly irreconcilable discrepancy of figures between those of the Amphibious Force, South Pacific, and the 1st Marine Division prevents a wholly accurate statement as to the number of troops embarked then or landed subsequently. Inasmuch as the Marine figures, contained in the division's Final Action Report, are not only themselves internally contradictory but of much later date than those of the Amphibious Force, it is probably that the latter are more nearly correct, and that 18,722 is close to the mark. On the other hand, however, the division records list, variously, 19,546 or 19,105.

At 0310, 7 August, the force was in position directly west of Cape Esperance, in two groups, with an interval of six miles and a speed of 12 knots, Transport Group X-ray itself was divided in two parallel columns, of eight and seven ships respectively with a distance of 750 yards between ships and an interval of 1,000 yards between columns. The shadowy rugged outline of the hills was just visible to starboard as the course was shifted to 040º, and a few minutes later the two groups separated for the completion of their missions. X-ray, shifting still further to starboard, settled on course 075º, which took it down the coast and parallel to it, while Yoke, on course 058º, crossed outside Savo Island, across a stretch of water that was later to be the scene of bitter surface engagements and where, a few hours later, four Allied cruisers were to be destroyed by a brilliant and daring strike by the enemy.86

It seems incredible that such a force should have been able to approach the landing beach undetected, but it is a fact that no signs of life came from the shore as the convoy ran down the coast. The final approach to the transport area was made without incident, and there was n sound until, at 0614, the supporting ships opened fire on the island.87

Chapter II: Landings on Tulagi and Gavutu-Tanambogo

Tulagi. The First Day

Task Group 62.2 separated from the larger body of ships at 02401 and approached Tulagi, its objective, over an independent course. The approach was accomplished without incident, the only departure from mechanical perfection being a failure on the part of the transports to keep closed up in formation. All elements of the group arrived in position at about 0630,2 and word came from Captain George B. Ashe, USN, commander of the Task Group stationed in Neville, that H-hour would be 0800.

As the ships approached the transport area, it was seen that the missions assigned to Support Group planes were being carried out. Strafing of designated areas (by Flight #101, 15 fighter planes, from Wasp took place at 0614, and dive bombing by Flight #102, 15 dive bombers, from the same ship) was under way at 0618.3. Fires were observed in the target area--seaplanes in the harbor, caught like sitting ducks, had been set afire.4

Naval gunfire preparation began with 5-inch fire from the destroyer Monssen, directed at a hill on a promontory of Florida Island, west of Tulagi, in the vicinity of the scene of the 2d Marines' first landing (see below). Sixty rounds were expended on the target between 0727 and 0732. In the meantime, both Buchanan and San Juan (an anti-aircraft cruiser) were pumping 100 rounds each into nearby targets, the former concentrating on another point of land east of Haleta, also on Florida Island, while San Juan directed its attention to a small island directly south of the same point of land.5

The first landing of the operation was carried out at 0740, 20 minutes before H-hour. In order to protect the left flank of the force executing the Tulagi landing, Company B (reinforced) of the 2d Marines, under command of Captain Edgar J. Carne, landed at that time on Florida near Haleta. The landing was unopposed, although enemy troops had been reported in position there on 25 July.6 Crane, whose force consisted of Company B, the 4th platoon of Company D, and 21 enlisted personnel from Headquarters Company, all of

Map 3: Guadalcanal-Tulagi Objective Area
Caption: Map 3: Guadalcanal-Tulagi Objective Area

1st Battalion, 2d Marines, was on his objective within 40 minutes. The 252 officers and men had come ashore in eight landing boats, and had been guided to their objective by one of the several Australians on duty with the division.7 [Platoon Sergeant Harry W. Schuler commanded the first landing boat, becoming the 1st American to set foot on Japanese-held territory in the Solomons. Sgt. Schuler was wounded 3 days later on Tulagi, and evacuated. See Annexes B & C to Op Order 5-42, attached.]

The main objective, the island of Tulagi, was attacked exactly on schedule. At 0800, under cover of gunfire from San Juan and destroyers Monssen and Buchanan (Fire Support Group Mike) the 1st Raider Battalion went ashore, followed by the 2d Battalion, 5th Marines.8 The landing was made at Beach Blue, 2000 yards from the northwestern end of the island on the western shore.

The island of Tulagi is a long, narrow, hilly, heavily wooded mass surrounded on three sides by extensive coral beds. It is approximately 4000 yards in extreme length and 1000 yards wide at its greatest width, which is fairly constant throughout the length of the island. Its long axis lies roughly in a northwest-southeast direction, and a regular, wooded ridge, 350 feet high, runs lengthwise through the northwestern two-thirds of the island. A smaller southeastern ridge presents a much less regular appearance and is separated from the other by a saddle which forms a sort of corridor between them, running directly across the island. Most of the development of the island was centered in the southeastern section around the coastline and in the corridor itself.

The island had been the seat of the British Solomon Islands Government, and the installations on its consisted of numerous wharves along the northeastern coast, a radio station, a prison, hospital, and other government buildings.

The character of the coast-line of the island presented a problem to those who had planned the landing. The only beaches which seemed to be suitable were those on the eastern and southeastern coast, and these were so dominated by high ground as to make an assault landing in the face of determined resistance an extremely precarious operation. It was finally decided to go ashore on the western coast of the island about 2,000 yards below the northwestern extremity, near the site of a small native cemetery. A map, now in Marine Corps Records, used in preparing the original plan shows the shore line in this vicinity to be badly overgrown with coral, and a notation regarding this growth appears on the map with the following wording: "Bordered with coral reefs. Due to uncertain tides landing not practical except amphibian tanks or rubber boats."

It is not unlikely that the enemy took the same view of the beach characteristics, for the landing here, as on Florida, was made without opposition. The report of one man falling before the fire of a single enemy rifleman, arose from the fact that one man of the Intelligence Section, 1st Raider Battalion, was killed by an accidental discharge while still aboard Little. He was brought ashore for burial.9

As the first waves approached the beach, the accuracy of the description of the coral beds was demonstrated. Not a single landing craft reached the beach. All of them hung up on coral formations at distances varying from 30 to well over 100 yards from the water line, and the assault personnel waded ashore through water initially from waist to armpit depth.10

By this time, the enemy defense forces (later found to be concentrated in the southeastern third of the island) realized that an all-out assault was under way, and not merely an air and surface force raid. Between 0725 and 0749, the Tulagi Communication Base was notifying the Commanding Officer of the 25th Air Flotilla at Rabaul that Tulagi was under bombardment, that the landings had begun, and that the senders were destroying all equipment immediately in view of the situation.

At 0800 the messages said that shells were falling near the radio installation. Ten minutes later, the final and prophetic message went out - "Enemy troop strength is overwhelming, We will defend to the last man."11

By this time, Companies B and D, of the 1st Raider Battalion, had just reached the beach and were to begin movement inland. There had been no opposition to the landing. Company B, reinforced, 2d Marines, was already on its objective on the Florida mainland southwest of Tulagi, likewise having met no opposition. The landing craft carrying Companies A and C, 1st Raiders, were beginning to hang up on the coral, and Company E, whose 60mm mortars had been attached to the rifle companies12 was on the way in to assume responsibility for beachhead security.

The terrain immediately behind the beach dictated the tactics employed. As Marines crossed the narrow beach and entered the undergrowth that bordered it, they faced a steep coral slope, also heavily wooded. This was the southwestern slope of the 350-foot ridge that runs along the length of the island in almost an unbroken wall. The two companies pushed ahead and across the ridge, Company B continued down the slope and occupied, without opposition, a small native village called Sasapi, on the opposite shore of the island. The company then swung to the right preparatory to beginning the advance toward the southeast. Company D, in the meanwhile, had swung right immediately after crossing the ridge line and likewise was ready to begin the advance, with its right flank on the ridge. For the rest of the day this formation was maintained, namely, Company D with its right flank on the crest line, its left flank in contact with Company B. Company B, in turn, was echeloned to the left rear with its left flank on the water's edge. The advance of these two companies was steady and without opposition until B Company reached Carpenter's Wharf, halfway down the east shore of the island, where it encountered a series of enemy outposts.13

In the meantime, the remaining companies of the Raider Battalion had come ashore. Colonel Edson, delayed by a breakdown in the boat which was brining him ashore, did not reach the beach until the initial movement (see below) down the ridge had begun.14 Companies A and C, comprising the second wave, followed closely upon the first wave and in turn were followed by Company E.

Company A, following the path of the leading companies, swung right immediately after reaching the crest of the ridge, tying in on the left with Company D. Company C, keeping its right flank on the beach, also swung right, typing in on the left with the right flank elements of Company A and echeloning itself to the right rear of that company. Company E, meanwhile, remained at Beach Blue and provided beachhead security. The progress of Companies A and C to the southeast was comparable to that of the companies to the left--no opposition was met until Phase Line A was reached at 1120.15

Progress had been steady in all portions of the line. Colonel Edson by this time had reached shore and had caught up with his advancing units, and was ready to begin an attack to the southeast. Fronting him was the more thickly settled portion of the island where the British Government activities of the Solomons had been centered. This area lay in a saddle between the two ridges of the island--the larger one to the northwest, which had just been swept by the advancing Raiders, and a smaller rugged hill mass that

formed the spine of the southeastern end of the island.16

Up to this time, radio communication between Edson and Brigadier General William A. Rupertus, the Assistant Division Commander (whose Command Post was still afloat) had been satisfactory. Fighting along the ridge had been sporadic and never severe, although number of isolated individual enemy troops had been bypassed during the advance.17 So successful had the action been


16. The Raiders had been well briefed on the terrain of the island by Lieutenant Henry E. Josselyn, RANR, a former resident of the area who had intimate knowledge of it. Major John B. Sweeney, in an interview on 4 February 1949, gave it as his opinion that the men of the battalion could have found their way over the island in total darkness, so lucid and vivid has the briefing been.

that Group Air Commander, Tulagi (flying from Wasp), reported from observation that Marines could be seen over the entire island. At 1404 he reported, most erroneously, that there was no opposition.18

At 1120, as we have seen, Phase Line A was reached and Edson was ready to advance. Preparatory to movement toward the saddle and the hills beyond it, fire was laid down on the area by all weapons of the battalion, save only the machine guns of Company E, which was still in position at Beach Blue. A noisy demonstration, this fire had no discernible effect.19

Radio communication between Rupertus and Edson began deteriorate immediately after the Raider Battalion reached the Phase Line. Thereafter, throughout the afternoon, the Assistant Division Commander knew only that the advance was progressing--he lacked immediate current details.

Actually, the first serious resistance of the operation developed almost as the lines began to move forward. Immediately to the front of Company C, on the extreme right flank position, there arose a knob like hill (Hill 208) forward and independent of the ridge which had just been swept. As the right flank elements of the company began to pass between the beach and the seaward face of the hill, 200 yards inland, they were taken under fire from automatic weapons emplaced on the face of the hill and from rifles. The situation was developed, and after an hour of fighting Company C cleared out the enemy positions by rifle fire and grenades.

Farther to me east, at the same time, the rest of Edson's force was likewise meeting opposition. As Company C was engaged in neutralizing Hill 208, Edson asked for, and received, naval gunfire against the southeastern ridge (Hill 281).20 San Juan complied with his request, made at 1240, laying down a seven minute, 280 round concentration of 5-inch shells on the designated target.

Four hours later, at 1625, Edson was able to notify Rupertus that 500 enemy had broken contact with his force and had withdrawn toward Hill 281, the southeastern ridge.

The advance continued slowly until dusk. By that time Company E, relieved of its mission of providing beachhead security by the 2d Battalion, 5th Marines (see below), had reported to its parent organization. Company D, on the extreme left flank, had met no opposition since midmorning, when it had flushed out the first resisting enemy encountered, near Carpenter's Wharf. This company had pushed south along the eastern beach and had got to the ridge line of Hill 281. Company B, now operating on the right of Company D, had likewise been able to advance without resistance until, just at dusk, it lost contact on the left with Company D and found itself in position on high ground overlooking a cut through which ran a cross-island roadway. Company D, on the far side of the road and to the left of B, went into position for the night with its right flank resting on the southern brink of the cut. Company B, with elements of Headquarters Company, rested its left flank on the cut and extended its lines generally westward along the brink.21 Both companies put out listening posts at intervals forward of the lines.

Companies A and C (less one platoon), meanwhile, had come squarely against a terrain feature that harbored the only serious resistance on the island. on the northwest slope of Hill 821 there was a deep ravine, running approximately east and west, which opened to the west, several hundred yards south of Hill 280. The long axis of the ravine, therefore, lay parallel to the advancing lines of the two companies. Its sides were precipitous, and within it the enemy had prepared positions which made an assault into it through the mouth possible only at the risk of high casualties. Maps that had been captured

and translated during the day confirmed that the ravine would contain the core of enemy resistance.22

Further action against the pocket was impossible at the time, and all elements of the battalion went into position for the night. Company D, on the left, was disposed as explained above, save that its flank elements were bent back to the beach to refuse the left flank. On the right, out of physical contact and separated from it by a cut, was Company B, with a part of Headquarters Company attached. Company E, which had reported to Edson late in the afternoon, was placed on Company B's right, while Companies A and C (less one platoon), respectively, were in position to the right of E Company and in contact with it. Their position ran along high ground facing the ravine and parallel to its long axis. Companies E, C, and A likewise put out listening posts.23

While Edson's battalion had been sweeping southeast down the island, another unit had come ashore. The 2d Battalion, 5th Marines (Rosecrans), had landed at 0916--a total of 1085 officers and men. The initial mission was to sweep the northwest portion of the island, which had as yet received no attention. The command post was established west of Beach Blue.

The battalion was committed piecemeal to various tasks. The northwest section of the island was swept by Company F, which reported no opposition. At 1000 Company E was ordered to operate generally in support of Company B (Raiders), and one hour later, the 3d Platoon of Company H (Weapons) was ordered forward to assist Company C (Raiders) in the latter's attack against Hill 208. By 1300, when the Raider Battalion had begun its movement forward from Phase Line A, Company G was ordered to go down the trail along the ridge line and report to Edson for duty in support of the Raider Battalion. The command post of Rosecrans' battalion was established first at Beach Blue, later in the day moving southeast toward the scene of action of the Raider Battalion.24

Tulagi. The First Night and Succeeding Day

The first night on Tulagi set the pattern for many nights in the Pacific War's future, for the devices employed by the enemy then were those he was to follow with an almost religious singleness of mind. Four separate attacks were launched against the Raiders' lines, and although minor penetrations occurred, in none of them did the enemy show signs of having thought beyond the mere fact of penetration. No attempt was made to consolidate the gains, and no evidence could be found that the Japanese attempted to exploit them.

Nightfall found the Marines holding positions as shown on the accompanying map. It will be seen that the Raiders' line followed the high ground around the ravine which, in the closing hours of the day, had proved to be the major obstacle to a complete cleanup of the island. One platoon of Company C was isolated, but not in trouble, on the southeastern tip of the island where, after having pushed ahead along the beach and having become separated from its parent company, it had established a small perimeter for the night. Company D, facing west with its line running

from the cross-island road up into the ridge line and back, on the left, until its left flank rested on the beach, was attenuated, but was not threatened. Company B, with elements of Headquarters Company attached, Company E, Company A, and Company C (less one platoon) were in position in that order from left to right, with Company C's right flank elements resting on the beach,. These four companies, closer to and facing the enemy pocket, enjoyed a degree of protection from the fact that the ridge which they occupied dominated the enemy positions They had, as we have seen, a line of forward positions in the form of a series of listening posts.25 The Raider Battalion command post had been set up at the Residency, formerly occupied by the Resident Commissioner, about two hundred yards north of the Company E sector.

Elements of the 2d Battalion, 5th Marines, were disposed to the rear of the Raiders' positions.

The first enemy attack--and one of the two that had some initial success--was driven home between Companies C and A. Forward positions were thrown back into company lines, and the two companies were forced apart. Company C was isolated from the rest of the battalion by the attack, but was not molested further. Company A refused its

dangling right flank, and awaited developments.

They were not long in coming. Shifting the direction of his attack toward his right front, the enemy force attempted to roll back Company A. The refused flank held, and no penetration was affected, 26 enemy being killed within 20 yards of the company's line.26

That was the last concerted attack of the night. Thereafter, enemy efforts consisted entirely of attempts at quiet infiltration of the Marine positions. Individuals and small groups worked their way from the ravine, through the lines, and launched five separate small scale attacks against the command post at the Residency between 0030 and 0530. These were repulsed without trouble. Efforts on the part of two other groups to make their way up the beaches past the extreme flanks of Companies D, on the east, and C, on the west, likewise were turned back.27

On the morning of 8 August, two companies of the 2d Battalion, 5th Marines, were moved into position to assist in the sweep of the southwestern part of the island. Companies E and F of that battalion went into position on the northeastern slopes of the Hill 281 after passing through Company D of the Raider Battalion. From that take off position they swept across the hill, down the southwestern slope, and swung right, moving toward the enemy pocket in the ravine.28

The troublesome terrain feature was now flanked on three sides, and the Marines were able to lay down a heavy concentration of mortar shells from the 60mm weapons of the Raiders and the more destructive 81mm mortars of the 2d Battalion, 5th Marines. By midafternoon the preparation was complete, and at 1500 the Raiders attacked from the northwest, aided by Company G, 5th Marines, and pushed through the ravine, wiping out all enemy resistance. For several days there was recurrent activity as isolated individual enemy riflemen and small groups of them were flushed out of their hiding places and hunted down. Organized resistance was over with the elimination of the enemy force in the ravine, however, and Tulagi had been retaken by the American forces by nightfall of 8 August.

JAPANESE SEAPLANE ANCHORAGE, GAVUTU-TANAMBOGO, as posted for convenience of pilots, was well punctured by small arms fire. Tanambogo is on the left, Gavutu, the right. Islet at the top is Gaomi.


These Siamese twin islets, each a small, flat affair dominated by a low, precipitous central hill of coral, were ligatured by a causeway 500 yards in length. The hill on Gavutu--148 feet in height and therefore named Hill 148--was slightly higher than its companion on Tanambogo which rose only 121 feet. This difference in height, catalyzed by the military rule of thumb which says that high ground dominates low ground, was a central factor in the making of plans for the assault.

The plans,29 in short, called for a landing on the northeast coast of Gavutu,30 with the landing craft coming in from the east. Since

30. The importance of Gavutu arose from the fact that there were numerous installations on the islet, including machine shops, jetties, and a radio station. The headquarters of Levers Pacific Plantations Proprietary, Limited, the great copra growing concern, was also located there. Sailing Direction for the Pacific Islands, Vol. I, p. 323. (Issued by the Hydrographic Office, Navy Department, in 1938. H.O. No. 165.)


Tanambogo lies approximately north of Gavutu and less than 1000 yards away, it can be seen that, granting the presence of enemy on Tanambogo, the assault force would meet with flanking fire as well as frontal resistance. Opposition from both directions would come from terrain which dominated the flat beach by virtue of height.

The assault itself was to be carried out by two companies of the Parachute Battalion, with a third company of the same battalion being kept in reserve initially for employment in support of the assault companies. Companies A and B, landing in that order, would attack the north and southeast faces of Hill 148 respectively, while Company C, plus attachments, would land last, go into position to the right (north) of the landing beach around the Gavutu end of the causeway. From this position it was expected that Company C would be able to offer assistance in the assault by interdicting the flanking fire from Tanambogo. When Gavutu was secured, Company C was to reembark, pass to Tanambogo, and size that island.31

Naval gunfire support was to be provided, as was close-in support from planes--SBDs from the carrier Wasp. It was expected that these two types of support would neutralize or eliminate entirely enemy emplacements on the hills. Gunfire would be effective, of course, only to the extent that the shells could reach the emplacements--those lying in defilade would be immune to damage. It was this type of protection that the dive-bombers were expected to overcome. A hardly foreseeable detail, and one that was destined to remain a major problem for Marine assault troops for the next two years of the war, was the coral cave. It began to appear as a troublesome obstacle for the Parachute Battalion at about the same time as the Raider Battalion, on Tulagi, was recognizing it as such.

There was to be no possibility of surprise. The hour for assault was set in General Vandegrift's Operation Order No. 7-42 as H plus four hours. Four hours after the Raider Battalion's landing on Tulagi (at a spot estimated to lie well away from the enemy's prepared positions) the Parachute Battalion was to make a frontal assault in the face of fire from an alerted garrison, which was supported by fires from a flanking position.

The battalion went ashore in three waves, one company per wave. The thoroughness with which San Juan had carried out her fire support mission--280 rounds of 8-inch fire against Gavutu in four minutes32--and the intensity of the dive bombing preparation33 caused heavy damage to the enemy installation. So completely had the island been blanketed, indeed, that the destruction worked to the disadvantage of the Parachute Battalion. For whereas the unit had intended to land on a seaplane ramp where it would be easy to get ashore, it was found that this installation had been reduced to an unusable mass of rubble. The landing craft therefore were forced to land slightly to the north and were exposed even more to flanking fire.34 Part of the troops had to scramble over a concrete pier standing four feet out of the water and exposed to fire from both islands. General Vandegrift estimated that ten percent casualties were suffered by the troops landing in the area.35

Company A, comprising the first wave, got ashore without casualties and began working inland without serious opposition. Four minutes later, the four-boat wave carrying Company B came in. This wave, however, and the final wave, carrying Company C and

Composed of four rather than five companies, its total strength was but 351 men, armed with Reising sub-machine guns, '03 rifles, Browning automatic rifles, and, in the case of three men, with Johnson automatic rifles. Light machine guns and 60mm mortars completed the battalion's armament. Each of its rifle companies had but 102 men--one of them, Company C, had only 77.

miscellaneous attachments, which followed it seven minutes later, were brought under fire immediately upon coming within range, during their approach, and during the landing. Company B, moving off to the left t work its way toward the southern end of the island, soon found itself partially protected from enemy fire, the greater part of which came from the northern face of Hill 148 (protected from naval gunfire by its position in defilade) and from Tanambogo. This company therefore continued to move.

The remaining companies, however, were by now under heavy fire that pinned them down. Within 20 minutes of the time the first landing craft touched the beach, Major Robert H. Williams was wounded, and command passed to Major Charles A. Miller, his Executive Officer.36 On the part of these two companies, movement was impossible until Company B worked its way into position to offer support with small arms and mortar fire.

By 1430, the battalion found itself in possession of the greater part of the island. Hill 148, the dominant terrain feature, had been assaulted on the east and the southeast. It had been possible to bring naval gunfire to bear on those slopes, and enemy resistance was thereby lessened to the extent that emplacements could be overrun. The southwest and west slopes, however, were to some extent in defilade, while the north and northeast faces of the hill were protected by flanking fire from Tanambogo. Fire from well protected emplacements on the Tanambogo side of the island continued to impede the movements of part of the already depleted battalion and to inflict further casualties upon it.37 Miller realized that Tanambogo must be reduced. he also realized that he must have reinforcements in order to accomplish this, and he requested them.38

In anticipation of their arrival, Miller also requested that an air strike and naval gunfire be laid down on Tanambogo. In compliance with the request, Wasp planes furnished a ten minute strike, and Buchanan and Monssen, in position south of Gavutu, fired over that island and subjected the exposed faces of the hill on Tanambogo to an intense concentration of 5-inch shell fire.

By this time all forces available to General Rupertus had been committed. on Tulagi the 1st Raider Battalion, reinforced by elements of the 2d Battalion, 5th Marines, was compressing the enemy into the ravine and was getting into the positions which it would hold for the night. Other elements of the 5th Marines were likewise carrying out special missions--Company E, operating near Sasapi, on the northeast coast of Tulagi, was about to be returned to he beachhead to provide security, and Company F was patrolling in the upper third of the island. The 1st Battalion, 2d Marines, (less Company B) operating without its supporting elements, had met with no opposition since landing near Halavo, opposite Gavutu on Florida Island. Company B, having carried out is mission of a pre-H-hour support landing opposite Beach Blue, likewise had made no contact with Japanese forces and was about to be withdrawn from the area.

Rupertus had not been informed by Miller of the number of reinforcements he needed. He therefore ordered Company B, by radio, to report to Miller on Gavutu for further employment. The message reached Company B as it was preparing to enter the landing craft (LCPs) that had been sent to take it off the island.39

The company, embarked in six landing craft, reported to Miller at about 1800 and was directed to land on Tanambogo and seize that island. Crane was told that the island was held by a few snipers. The landing craft,

At the moment, one of the supporting aircraft, an SBD, placed a bomb of undetermined size squarely upon the summit of the hill. This mistake in target identification cost the company two men killed and several wounded. A similar error caused more casualties next day in the same spot.

badly overcrowded, were guided around the east shore of Tanambogo by Lieutenant Spencer, RAAF, and under cover of darkness attempted a landing on a small pier on the northeastern tip of the island. One boat, containing the 2d Platoon, had hung upon the coral coming into Gavutu and did not take part in the assault on Tanambogo.

The first boat landed without incident, and the men began deploying along the beach. As the second boat was discharging its platoon, however, a shell from one of the fire support ships landed in a nearby fuel dump, and the resulting glare lighted the landing area and exposed the Marines. The enemy opened up immediately, taking all boats under rifle and machine gun fire. Casualties were caused among the Marines ashore and still afloat, but the boat crews suffered most heavily, being exposed. One crew suffered total casualties, and the operation of the craft was taken over by one of the Marines embarked.

The machine gun platoon embarked in the second boat (4th Platoon, Company D) managed to set up two of its weapons on the pier, but the intensity of fire directed by the enemy at the exposed and well illuminated position forced it to withdraw.

In the meantime, Crane and about 30 men had gone ashore. The intensity of resistance, however, made withdrawal inevitable, and Crane succeeded in reembarking all wounded and all but 12 of the able survivors. The boats withdrew, some to Gavutu where they reported the event, and others direct to the ships, where the wounded were taken aboard. Two men of those left on the beach managed to return to Gavutu at about 2200 in a rowboat, while Crane and Lieutenant John J. Smith, leader of the 2d Platoon, and the rest of the dozen men made their way around the beach and over the causeway, arriving at Miller's command post at about midnight.40

After nightfall, action continued. The enemy on Gavutu were reinforced by individuals who swam to the island from Florida and Tulagi. A strong group sallied from a cave under the southern slope of Hill 148 and counterattacked, without effect. The entire group was wiped out. Other enemy, coming ashore at various points around the island, under concealment of heavy rain, attacked and caused a small number of casualties without, however, altering the fact that the Parachute Battalion controlled the island.

At 2200, having been informed of the abortive attack on Tanambogo, General Rupertus requested the release of an additional combat team. This request, reaching Vandegrift during his conference with Admiral Turner on board the USS McCawley, was acted upon immediately. Vandegrift, Turner concurring, decided to release the remaining two battalions of the Division Reserve (2d Marines reinforced). At 0330, 8 August, the USS President Hayes and President Adams, with the 2d and 3d Battalions, 2d Marines (reinforced) embarked, were ordered to proceed from the transport area off Beach Red at Guadalcanal to the Tulagi transport area. Orders were issued at the same time to the battalion commanders to land their troops at Beach Blue and report to General Rupertus for duty.41

Upon arrival at the transport area off Beach Blue at 0730, the 3d Battalion, 2d Marines was directed to pass to Gavutu to reinforce the troops engaged there and seize Tanambogo. Orders for the 1st Battalion were not changed.

The 3d Battalion, under Lieutenant Colonel R.G. Hunt, landed in a series of 3-boat waves, spaced at 10-minute intervals, with companies in the following order:

Company L, with 5th Platoon Company M attached, at 1000;

Company K, with 4th Platoon Company M attached, at 1025;

Company I, with 3d Platoon Company M attached, at 1050;

Company M, less 3d, 4th, and 5th Platoons, with Headquarters Company, at 1120.

Upon landing, Lieutenant Colonel Hunt assumed command of the operation. Troops were deployed initially to eliminate all remaining opposition on Gavutu.42

At 1225, Captain W.B. Tinsley, commanding Company I, was ordered to prepare for a landing on Tanambogo. He would have the support of two tanks from the 2d Tank Battalion (one of the reinforcing units of the 2d Marines), and his attack would be preceded by a 10 minute naval gunfire preparation by Buchanan. The company would not be accompanied by its supporting machine gun platoon, which was to stay in position on Gavutu and lay down supporting fires from there.

At 1315 the tanks landed on Gavutu and Lieutenant E.J. Sweeney, commanding them, was ordered to land at 1615 on Tanambogo, using one tank to cover the south side of the hill on that island and the other to cover the eastern slope.

The naval gunfire preparation was laid down as planned, beginning at 1600. Twenty minutes later the assault company landed preceded by the tanks. lieutenant Sweeney, while observing from one of them, was killed, but his vehicle rendered valuable support to the riflemen. The other tank, getting too far ahead of the assault troops, was disabled by an iron bar and set afire by enemy riflemen who used oil-soaked rags. The entire enemy group was wiped out, 42 bodies being piled up around the disabled tank.

At 1620 Company I landed and separated in two groups, one of which worked up the southern slope of the hill and the other, moving off to the right and then inland, fought its way up the eastern slope. Heavy resistance was encountered, coming from small enemy groups in position in dugouts and caves in the coral. The eastern group's position was made more dangerous by the presence of a few enemy riflemen and machine gunners on Gaomi, a tiny islet lying directly east of Tanambogo and only a few hundred yards away. Naval gunfire was requested again, the time from Gridley, and was laid down at 1700 on Gaomi. The interference from that point ceased abruptly.

Immediately after the establishment of the beachhead on Tanambogo, a supporting attack was launched across the causeway, at 1700, by the 1st Platoon of Company K. This platoon secured the Tanambogo end of the causeway and took up positions for the night in that area. At 1900 Company I was supplied by boat with ammunition from Company M.

By 2100 the southeastern two thirds of the island had been secured, and at 2300 a light machine gun platoon from Company M reported to Company I for support against enemy counterattacks. Considerable close in fighting took place during the night between the Marines and individuals or small groups who sallied from foxholes and dugouts. No change in position occurred, however, and late the next day the island was completely secured.

While the 3d Battalion, 2d Marines, was assisting in the clean-up on Gavutu, and while one company was securing Tanambogo, the other two battalions of that regiment, with a part of the supporting troops, were coming ashore on Tulagi. The 1st Battalion, unengaged since landing on 7 August on Florida, went ashore at Beach Blue at 0900, followed one hour later by the 2d Battalion.

Here, as at Guadalcanal proper, the amphibian tractor began to emerge as a versatile piece of equipment whose importance and utility could hardly be overestimated. From noon of 8 August throughout the following night, five of these vehicles of the 3d Platoon, Company A, 2d Amphibian Tractor Battalion (one of the reinforcing elements of the 2d Marines) operated between Gavutu and the President Adams, where the platoon had been embarked. Carrying water, supplies, and ammunition, as well as personnel, on the ship-to-shore trips, they acted as ambulances on the return trips, evacuating wounded. On one occasion a tractor operated far inshore, interposing itself between a

group of wounded men pinned down by fire from an enemy dugout and the emplacement whence the fire was coming. Using its two machine guns--one .50 caliber and the other .30 caliber--to neutralize the enemy fire, the tractor picked up the wounded and evacuated them. The five tractors of the platoon were taken back on board the Adams before sundown, 9 August.43

With the fall of Tanambogo, the last organized resistance in the island groups ceased, and subsequent operations consisted of mopping up and the establishment of defense. Under the head of mopping up, however, came the taking of several small peripheral islands--Makambo, Mbangai, Kokomtambu, and Songonangona.44 Gaomi, which had caused temporary annoyance to he members of Company I as they were busy on Tanambogo, had been silenced conclusively early in the morning of 9 August by Battery I, 10th Marines, which laid in 60 rounds of 75mm (pack howitzer) fire from its positions on Gavutu.45

The mission of clearing out these small foci of infection was delegated to various units of the 2d Battalion, 2d Marines. Makambo was taken by Company E, Mbangai by Company F against slight opposition, and Kokomtambu, with Songonangona, by Company G, which also encountered minor resistance. Occupation of all these smaller islands was completed during the morning of 9 August.

The taking of the entire Island group - Tulagi and its satellites - had been accomplished in three days. The entire enemy garrison, with the exception of a few survivors who made their way to Florida Island (and to ultimate capture or extinction by native and Marine patrols), was wiped out. A few prisoners were taken, questioned, and sent to rear areas, most of them finally being placed in a prisoner of war camp near Featherstone, New Zealand.

Comparatively, the American losses were not excessive. An early report by Rupertus to the effect that the Parachute Battalion had suffered 50-60 percent casualties can only be explained in terms of inadequate communications between him and his troops ashore.46

The exact number of enemy casualties will never be known. It was estimated that about 1500 enemy, including several hundred conscript laborers, were present on the various islands of the group at the time of the landings. Twenty-three prisoners were taken, and an intelligence summary gives 70 as the approximate number of survivors who escaped to Florida. The distribution of enemy forces, as given in the Final Report, the source for the figures given herein, was about 500 on Tulagi (all Landing Force and Naval Aviation personnel) with the remainder on Gavutu, Tanambogo, and the smaller islands.

were rounded up and wiped out, Tulagi and its satellite islands were organized for defense against counterattack. The Parachute Battalion shaken by its experience on Gavutu, was moved from that island at 1700 on 9 August to Tulagi, where it went into position in the Government building area. The 2d Battalion, 5th Marines, occupied the southeastern sector of the island, while two battalions of the 2d Marines took over the defense mission in the northwestern two-thirds, the 1st Battalion at the extreme end of the island and the 2d Battalion at Sasapi. Third Battalion, 2d Marines, took over the occupation and defense of Gavutu, Tanambogo, and Makambo.47

The logistic problem on Tulagi was, in miniature, that which was encountered on Guadalcanal and which well be discussed in detail below. Certain details peculiar to Tulagi complicated the problem, however, and should be mentioned here. The beachhead, for instance, was severely restricted in character, and there were no usable roads. Only after noon of the second day was it possible to move supplies ashore at the piers on the eastern coast.48 At Gavutu, in effect, there was no beachhead, and only ammunition and water could be moved in until the islands were secured.

The supply situation may best be summed up by the following comments from officers of two of the units involved.

E-2-5 landed with three days' rations, and received nothing but captured rice and one (1) 1-gallon can of tomatoes from 7 August until 21 August, when we were transferred to Gudalcanal by APD's. One meal per day from 11 August on.49

The Parachute Battalion landed on Gavutu with weapons, ammunition, medical supplies, and two or three days' supply of "C" and "D" rations only. Prior to embarking in landing craft, each individual made up a roll which consisted of clothing, mess gear, necessary comforts of life, and field bedding. These rolls, together with vital organizational equipment were loaded in landing craft. Almost all these rolls, with most equipment were never received, thus causing undue hardship and inconvenience after the Parachute Battalion moved to Tulagi.50

Another officer has an explanation of the failure of the individual rolls and equipment to reach shore. According to this account, which is substantially the same as the above, the equipment was placed in the landing craft after they reported back to the Heywood, their mother ship, when the troops were put ashore.

An air raid warning occurred as the boats loaded with the packs were almost to the beach, and without allowing them to proceed and unload they were recalled to the ships, and coxswains ordered to throw the gear over the side in order to lighten them sufficiently for cranes to swing them aboard.51

Large quantities of Japanese material were found, including considerable amounts of documentary intelligence matter. Some food, as we have seen above, was also taken, and, like the engineering and radio equipment, was put to immediate use.

The Tulagi area, after the first three days, became quiet. Enemy planes by-passed it in striking at the more tempting air field and perimeter on Guadalcanal. Surface craft shelled it occasionally, but never was it subjected to the kind of bombardment that struck Guadalcanal in October. There is no record that enemy forces landed either on Tulagi or on Florida.

The island served as a base from which were mounted several of the more important patrol actions of the campaign--to Savo Island, to Malaita, and to Guadalcanal itself.

Chapter III: Guadalcanal--The First Three Days

Task Group X-RAY, containing the Guadalcanal assault Forces, separated from Task Group YOKE northwest of Cape Esperance and approached the transport area off Beach Red in double column at 12 knots.1 No sign of enemy activity was encountered and the preliminary naval bombardment of the coastal area, which began at 0613, elicited no response. At 0645 the transport area was reached. Five minutes later the signal "Stop" and "Back" came from the Hunter Liggett, followed immediately by the traditional Navy signal to commit the troops--"Land the landing force." The double column dropped anchor and stopped in perfect formation, and landing craft began moving over the sides.

The command post of the division had opened on board the McCawley at 0519.2 Eight minutes later, General Vandegrift was asked by Admiral Turner to set the time for H-hour. He did so, selecting 0910, and then, as news of the successful landings on Florida and Tulagi began to come in, the first waves of assault troops moved toward Beach Red.3

There was still no sign whatever of incipient or potential opposition. At 0859, 11 minutes before the first troops were scheduled to go ashore from the landing craft, reassuring words came from an observation plane from Astoria operating in the vicinity of the beach. No enemy could be seen in that area.4 Fifteen minutes later, however, word came from the same source that trucks were moving on Lunga Field, several thousand yards west of the landing beach. This news brought forth a request for an air strike against that area. While the request was being complied with, by VS-3s from Saratoga5 a message came from the beach that the troops were going ashore at 0919.6 There was no opposition at the beach.

Intelligence Situation

In order to understand the plans for landing and for the subsequent maneuvering of the troops, it is necessary at this time to review the intelligence situation as it existed from the beginning.

To put the matter succinctly, the division planners and ultimately all echelons of command above that level had only the haziest idea of the terrain of Guadalcanal. Sailing charts which contained data assembled over a period of years from official hydrographic surveys and from information given by navigators contained little that could be used by a staff planning a land campaign on Guadalcanal. No maps worthy of the name were in existence. It had been necessary, as we have seen, for the Intelligence Officer of the division to enlist the services of former residents of the territory and get from them, by word of mouth, some idea of the terrain upon which the division was to operate.

The information so gathered was extremely

spotty in quality. Whereas it was possible for the planners to get a good idea of the character of that portion of the island immediately adjacent to the coast, and particularly that portion which was threaded by the small coastal roads and trails, it was impossible to obtain any detailed information whatever regarding that part of the island which lay inland, away from the cultivated coastal area. It soon became apparent, indeed, that while the British or Australian residents of the district had a fair knowledge of the territory immediately surrounding their area, they were nearly as ignorant as the newcomers about the terrain features of the jungle-covered interior of Guadalcanal.

Two outstanding examples of the faulty nature of this advance information can be pointed out here. The first example is more amusing than important--that which has to do with the scrambling of the names Ilu and Tenaru. Three rivers flow into the coastal plains in the vicinity of Beach Red. The largest and by far the most important is the Lunga, and about that there was never any doubt. The second most important from the point of view of the landing is a long and relatively swift stream arising in the foothills behind the plains and descending to the sea in a series of broad, shallow rapids and deep, almost stagnant pools. In general character it resembles the Lunga, which also is long and varied in appearance. Between these two rivers lies another completely unlike them in appearance and characteristics, a deep, sluggish, lagoon-like body of no great length.

According to the earliest chart available (No. GC 146, 1937), the river which constituted the western boundary of Beach Red is the Tenaru. Flowing into this river almost at the mouth and from the right bank, there is a small stream which, in the days before the war, was known to the natives as the Ilu. The sluggish stream between the Lunga and the Tenaru seems to have been unnamed by the natives since its relatively short length and its similarity to countless other lagoons on the coast reduced it to comparative unimportance from their point of view.

Basic to the misunderstanding in the subsequent Gordian tangle of the names is the fact that near the mouth of this lagoon there stood a native village called Tenaru. Pilot Officer Charles V. Widdy, RAAF, a former resident of the island and a volunteer for duty with the division, is said to have pointed out the village and said that it was Tenaru. He was thought to be referring to the river and the name was attached to the undeserving creek. Since it was also known that the Ilu was a stream lying to the east of the main body of the Tenaru, logic demanded that the name be attached to the long swift river at the extremity of Beach Red.

Much alter, when Army forces on the island were busy with cartography, they attempted to rectify the situation, and with something approaching logic they contended that if the Ilu really was the Tenaru, then the Tenaru must, of necessity, be the Ilu. This reasoning was followed on maps that were made subsequently, and the rivers were so marked on signs erected upon the bridges that crossed them. So involved did the whole matter become, indeed, that it had unforeseen repercussions, for by 1945, the natives, hopelessly confused by the controversy were themselves no longer sure which river was which.

So the matter stands today, but the first and perhaps the decisive land action of the campaign was fought at the mouth of the unnamed lagoon known temporarily and erroneously as the Tenaru. later in the campaign, the lagoon became known as the Alligator Creek - it had no native name - and the Tenaru once more bore its correct name. For the purposes of this monograph, the name Alligator Creek will be used, and the battle fought at its mouth will continue to be known as the Battle of the Tenaru.

The second example of erroneous information--given and received in good faith - was that dealing with the terrain feature known as Mount Austen. In General Vandegrift's operation order, the 1st Marines were assigned an objective described as a grassy knoll four miles south of Lunga. This knoll had been described several times to planners


by former residents as the commanding terrain feature of the vicinity, and the implication was that it was close to the Lunga plains and easy of access from them.

The advance information about Mount Austen was correct in only one respect--it was a commanding terrain feature. The idyllic name of "Grassy Knoll" actually described a rugged truncated hill mass some 1500 feet in height, covered with alternating patches of rain forest and kunae grass, surrounded on its lower reaches by a chaotic system of cliffs, ravines, and gorges--all overgrown with lush and almost impenetrable vine growth. It lay, furthermore, perhaps six miles west and eight miles south of Lunga Point, which would place it some ten miles southwest of Beach Red, and was separated from that beach by rivers, jungles, precipitous ravines, and small plains covered with six-foot kunae grass. Parenthetically, it may be said here that Colonel Cates, commanding the 1st Marines, realized almost at once that the possibility of his attaining that objective was so remote as to be fantastic, and General Vandegrift, upon receipt of his advice concurred immediately. As a matter of act, the hill mass presented a constant threat to the airfield and to the troops in the vicinity of it in spite of constant patrolling begun immediately after the perimeter was set up.

Lest is seem that this matter of faulty intelligence is being labored, it must be emphasized, that in this, the first land offensive of American forces during the second World War, the plans which were formulated for the initial assault were based on nebulous, often contradictory, and seldom accurate information. The fact that the character of such information was recognized quickly, and that plans for continuing the campaign were changed radically in accordance with correct data, speaks eloquently for the ability of General Vandegrift and his staff to improvise quickly and effectively.

Information regarding the size of the enemy force on Guadalcanal was meager in the extreme. Coastwatchers on the island had kept as close a watch as was humanly possibly and had forwarded the information so obtained through their regularly established communications channels.7 They had likewise made use of information obtained from loyal natives whose good faith was unquestioned, but whose mathematical powers were not too well developed. On the basis of such data, it was at first estimated that approximately 5,000 enemy were present in the Lunga district.8 It was thought that this total included about 2,100 labor troops, a reinforced infantry regiment, and an antiaircraft battalion.9

The plans for the attack of necessity had to be based upon such information as was at hand, and they called for a landing which would take advantage of, first, the probably localization of enemy forces around Lunga Point and, second, the characteristics of the terrain itself. Since it was understood that the enemy would be concentrated in the vicinity of the airfield then under construction, and since a direct frontal attack was to be avoided if possible, it was decided to select a beach far enough from the area to allow time for landing and deployment of troops, and for maneuver prior to actual assault. It was desirable also to select a beach the configuration of which was such that some protection could be obtained from the terrain itself.10

The beach finally chosen lay about 9,000


7. Reference is directed to The Coastwatchers, by Commander Eric Feldt, RANR.
8. An estimate of the situation, prepared by the division while in Wellington, on 11 July 1942, suggested a total of 5,000 including one infantry regiment 3,360), one engineer battalion (375), and miscellaneous combat and labor personnel (1,265). A revised estimate, dated 27 July, gives the same total but a slightly different breakdown. Both documents are contained in folder 3K, Guadalcanal Documents, Marine Corps archives. No basis can be found in documents for the estimate of 2,100 laborers which is contained in the Final Report, Phase II, p. 9.
9. It is interesting to note that even Japanese sources are ambiguous on the point of the actual number present on the island on 7 August 1942. Wording of translated Japanese documents is such as to justify a round figure of perhaps 2,000, of which the greater part were laborers.

yards southeast of Lunga Point. A strip 1,600 yards in length was selected at the deepest point of a gentle re-entrant in the coast-line. The right flank (northwestern extremity) of the beach was marked by the Tenaru River, which, it was thought, would offer a natural line of defense against any possible interference with the landing from the west or the northwest. The eastern extremity had no such natural protection.

The First Day

Operation Order 7-42 called for a landing on Beach Red by the 5th Marines (reinforced), less 2d Battalion (employed on Tulagi). This group would land with its remaining two battalions abreast, 1st Battalion going into position on the right. The 3d Battalion was to go into position immediately on the left (southeast) flank to act as beachhead defense against enemy activity from that direction. The 1st Marines (reinforced) would land at H-hour plus 50 minutes in column of battalions, 2d Battalion leading and followed by 3d and 1st Battalions in that order. Immediately upon landing and assembling, the regiment would pass through the right section of the beach and attack almost due west on an azimuth of 260 degrees, battalions echeloned to the left rear in order of landing. Its mission was to seize Grassy Knoll and to be prepared for further advances. The

1st Battalion, 5th Marines, meanwhile would advance west and secure the line of the "Tenaru" River (actually Alligator Creek.) The Support Group, consisting of Headquarters, 11th Marines, and all other division troops not employed on Tulagi, was to land on order over Beach Red.

Six floatplanes were supplied the assault forces by the heavy cruisers to Task Force 62. Three of these, from the USS Astoria, were used as liaison planes whose first duty was to mark the extremities of Beach Red with smoke so that the target area would be clearly visible to the transports and the landing craft. Three additional planes were supplied by the Quincy for use as spotting planes by the 11th Marines, the division artillery.11

The actual landing was accomplished as planned, with dispatch and without opposition. By 0938, regimental headquarters of the 5th Marines was ashore, and its first command post had opened about 100 yards inland. The 1st Marines had accomplished their part of the landing operation by about 1100, for by that time the regiment was beginning to pass through right elements of the 5th Marines.12

By 1400 the 1st Marines were well on the way to carrying out the assigned part of their mission. Message #75 (D-3 Journal, 7 August) contains the following message:

"1410 Troops getting along OK on beach river holding them back one-half mile inland."

Movement of troops from the beachhead began at this time. At 1400 the 1st Battalion, 5th Marines, had been ordered to move off toward the west to secure and occupy the line of Alligator Creek, upon which it was to take up positions for the night. The battalion, with regimental headquarters and the Weapons Company, began to move at once, while the 3d Battalion remained in position covering the southeast flank of the beachhead.13

The 1st Marines, however, realized almost at once that it would be impossible to get on the Mount Austen objective.14 The hill mass which had been so designated, and which had been visible from the ships, could not be seen from the beach. Furthermore, the regiment was passing through unexpectedly rough terrain and was learning that the banks of the Tenaru, which would like a snake back and forth across the regiment's line of advance, were steep, thickly overgrown, and difficult of passage, and that the river itself was not fordable.15

At 1430, Colonel Cates reported that he was still passing through the right front of the 5th Marines and that no contact had been made as yet with the enemy.16

At about this time the Support Group was coming ashore from the ships of the Transport Group, which had moved in to within 2,000 yards of the beach. At 1515, General Vandegrift notified Admiral Turner that his command post was opened on shore, as 45 minutes later the General himself was on the beach.17

Austen. Cates did so that night at a conference with Vandegrift. Interview, Colonel William W. Stickney, 15 January 1949.

Warned by Pilot Officer Widdy, during the rehearsals at Fiji, that the rivers and lagoons would be deep, members of the Engineer Battalion rigged a rough bridge of dunnage and timber (irregularly acquired on board ship) and sent it ashore on board two tractors. The two vehicles were driven into the Ilu backwash, a small stream flowing into the Tenaru at its mouth from the southeast, and formed pontoons across which the jury-rigged bridge was thrown.

By nightfall, the units ashore were in position as shown on the accompanying map.

Several important lessons had been learned during the first day's operation. The ship-to-shore movement had been a gratifying success. Two reinforced regiments, and all division troops, had landed on Guadalcanal; the regiments had carried out their assigned missions where it was geographically possible to do so.18 The landing was carried out with something of the ease with which a similar maneuver might have been accomplished in a peacetime drill. The fact that no enemy opposition was encountered was conducive to smoothness of operation, but even taking this into consideration, the entire D-day operation from the point of view of the Commanding General, who was bringing his troops ashore for combat, was an outstanding success.

The movement of supplies, however, from the landing craft to the beaches and ultimately to the supply dumps, was an entirely different matter. Certain phases of this operation were characterized by the same smoothness and efficiency as the troop movement. Specifically, unloading from holds to landing craft and movement to the beach proceeded according to schedule. Once the landing craft touched the beach, however, they encountered a situation which, almost as the first craft landed, began to deteriorate. Captain L.F. Reifsnider, Commander of Task Group 62.1, reported as follows:

A serious situation developed early during landing operations when the labor section of the shore party was unable to cope with the rapidity and quantity of supplies and equipment delivered at the beach. The situation is ascribed to a total lack of conception of the number of labor troops required to unload boats and move material off the beach, failure to extend the beach limits earlier in the operation, and, to some extent, lack of control of troops on and in the immediate vicinity of the beach--it was definitely understood and agreed that the unloading of the boats and the removal of material from the beach would be done by the labor section of the Pioneer Battalion. .  .  .19

By the terms of Landing Operations Doctrine, United States Navy, (FTP 167) Chapter 2, Section II, paragraph 212 (a), the unloading of the material of the Landing Force form small boats was a task to be performed by the military component of the Shore Party. Reifsnider's reference to the Pioneer Battalion is interesting in that only 310 men of that unit were present as a body and even these had been assigned an active defense role as part of Colonel del Valle's Support Group. The rest of the battalion had been parceled out to various regiments as reinforcing elements. A feeling comment on the subject of the relationships between the Shore Party Commander and the Naval [Task Force] Commander is contained in a 12 February 1949 letter to the Commandant of the Marine Corps from Colonel Frederick L. Wieseman, who commented on the matter under discussion as follows:

The initiation of general unloading by the Naval (Task Force) Commander is a matter that should be prevented by custom, doctrine, high command, Joint Chiefs of Staff Directive, and force of arms if necessary. .  .  . Nothing should be landed on a beach unless the Shore Party Commander has OK'ed its dispatch.

Reifsnider's complaint, however, justified in terms of the undeniable fact that supplies were piling up on every beach, is nevertheless an example of the somewhat remote viewpoint of the observer afloat who may be conversant with only his own part of the picture. What had happened in fact was that General Vandegrift, on the basis of what intelligence he had, was anticipating momentarily commencement of a meeting engagement of major proportions, at some point short of his objective, the airfield. As a result, although the Division operation order had provided that the Shore Party might call upon unit

19. Action Report, Task Group 62.1, p. 9. Provision for handling of supplies was set up in Force General Order No. 7-42<, 25 February 1942. This in turn formed the basis for the supply section of 1st Marine Division Administrative Order 2a-42, which accompanied Operation Order 7-42. Paragraph 6 (a) of the Administrative Order directed Shore Party Commanders to call upon troop commanders in their immediate vicinity for assistance in the handling of supplies from landing beaches to dumps. It nowhere directed that a troop commander upon whom the request was made would necessarily comply.


commanders for additional labor, no units as such were being held on the beaches, but were in or enroute to assembly areas preparatory to the anticipated battle. Consequently they could not be made available for labor purposes, however important this might seem. Captain Reifsnider's "hundreds of Marines" (as reported by seamen and observed from on board the Hunter Liggett) were largely the rear elements of units already engaged in the slow advance through the jungle toward the field.

At 1321, Admiral Turner had directed Captain Reifsnider to expedite unloading.20 By 1449 the advance message center was advising General Vandegrift that the shore party commander was badly in need of at least 500 men to help unload boats.21 It said further that no men were available on the beach for that function. Less than an hour later, Reifsnider informed General Vandegrift that 15 men from each cargo ship were being detailed to help unload boats until they could be relieved by pioneers.22

This measure was in the nature of makeshift, and the constant stream of material arriving at the beach could not be handled. In spite of the fact that every effort was made, at one time 100 loaded boats had been beached while 50 more were standing by just outside the breakers waiting an opportunity to land. So chaotic had conditions become that, by 2330, the commander of the Shore Party reported to General Vandegrift, that unloading was entirely out of hand;23 that supplies were arriving much faster than they could be handled; and that it was imperative that the ships cease unloading until the beach could be cleared. Three hours later Admiral Turner advised General Vandegrift that his24 request was being carried out.

Enemy activity during the day had been confined to air strikes launched from Rabaul. At about 1100, a coastwatcher stationed in the Upper Solomons reported that a force of 18 bombers had just passed his station, headed for Guadalcanal. At 1320 this force appeared, striking ineffectually at ships in the transport area off Beach Red.25 The destroyer Mugford was hit by a 250-pound bomb and suffered 20 casualties, but no other vessel in the group was touched. The attacking planes were reported to be twin engine Type 97s. Two were shot down by antiaircraft fire from the ships.

A second attack came at about 1500, when the same area was struck by ten 99 Aichi dive bombers.26 No damage resulted from this strike, and again two enemy planes were brought down by antiaircraft fire. In neither attack was any attempt made by the Japanese to damage material on the beach.

During the first night the only disturbance which occurred resulted from the nervousness of some troops who lacked combat experience and who were in unfamiliar surroundings without definite knowledge of the size or whereabouts of the enemy forces to their front. No Japanese activity was noted, but there was considerable firing in the area to the west and northwest of the beachhead, in the zones occupied by the 1st and the 5th Marines. Both regiments suffered casualties as a result.27

General Vandegrift's Change of Plan

At 2200 on 7 August the two regiments were informed of a change in plans.28 As we have seen, the objective of the 1st Marines was too far removed to be possible of attainment. With less than a division of troops--for the reserve regiment, which would have brought the infantry strength up to normal,

Its assault would have required the separation of a major unit from the main body, and in such a case liaison (where possible) would have been difficult in the extreme. The logistics of the movement would have been appallingly difficult.

The plans for 8 August, therefore, called for occupation of the airfield and establishment of a defensive line along the Lunga River. Those elements of the division which had been assigned the mission of establishing and maintaining defensive positions along the eastern and southeastern boundaries of Beach Red were ordered to continue that mission.

At 0930, 8 August, the 1st Battalion, 5th Marines, supported by Company A, 1st Tank Battalion, crossed Alligator Creek at its mouth and advanced toward the Lunga with its right flank on the beach. The advance was cautious and deliberate. In the meanwhile, the 1st Marines, who had spent the night along the Tenaru River south of the positions occupied by the 5th, began their advance to the west. The 1st Battalion, 1st Marines, was somewhat hindered in its advance by the fact that it had to cross the creek some 500 yards inland from the mouth. The 2d and 3d Battalions, however, skirted the headwaters and plunged immediately into the thick jungle growth which lies to the south of the airfield. Contact between units was faulty due to their failure to patrol to the front and flanks.29

By nightfall the regiment had attained only part of its objective. The 1st Battalion had overrun the airfield and had succeeded in reaching the Lunga; the 2d and 3d Battalions, however, slowed down by the difficult terrain to a rate of approximately 500 yards per hour, went into bivouac south of the airfield.

The advance of the 5th Marines had been without incident of a serious nature. In reaching their objective they had traversed the area which had been occupied by the main Japanese force. First enemy resistance, from scattered individuals had been met and several prisoners had been taken. From them, as well as from captured documents, it was learned that no serious resistance was to be expected for the time being. The negative nature of all information from front line units verified this. At 1430, therefore, the regiment was ordered to contract its front, to cross the Lunga by the main bridge immediately north of the airfield, where the

main road cuts inland to avoid the several branches of the river near the beach, and to advance in the direction of Kukum. This movement was accomplished with Weapons Company in advance, and at 1500 Marines reached the main Japanese encampment.30

It was immediately obvious that the enemy force was smaller than had been thought and the fact was confirmed that the Japanese had retreated in a state bordering on complete demoralization. Large quantities of food, ammunition and equipment were found in perfect condition, and much engineering materiel, electrical apparatus, and radio equipment was captured intact. There had been no attempt at demolition by the enemy. There was some destruction by Marines initially because of lack of proper indoctrination, but this condition was corrected almost at once. The only damage apparently had been caused by the bombardment preceding the landing, and the completeness of the enemy installations are well described in the final action report as follows:31

The extent to which the enemy had been able to develop their Lunga Point positions was remarkable in view of the short time of occupation. Since July 4th they had succeeded in constructing large semi-permanent camps, finger wharves, bridges, machine shops, two large radio stations, ice plants, two large and permanent power plants, and elaborate air compressor plant for torpedoes, and a nearly complete airdrome with hangars, blast pens, and a 3600 foot runway.

The most serious enemy activity during the day had consisted of a repetition of the retaliatory measures of 7 August. Soon after 1100, warning was received from Pilot Officer Cecil John Mason, RAAF, a coastwatcher stationed on Bougainville, that a large number of planes had been sighted over his post, flying southeast.32 At noon they appeared over the area to find that all ships of the task force, alerted by the warning, were at maximum speed.

Approximately 40 twin engined torpedo planes participated in the attack. Two ships were lost. The destroyer Jarvis, hit forward by a torpedo, managed to leave the area under her own power but disappeared with all hands while making her way to the southeast. The transport Elliott, set afire when an enemy plane crashed on board, had to be beached and destroyed by her sister ships. Survivors were taken aboard the Hunter Liggett.

Twelve of the attacking planes were shot down in the vicinity of the ships by antiaircraft fire from the ships and by fighter planes from Admiral Noyes' carriers operating to the south. Two more were accounted for by shore-based antiaircraft weapons. Still others were shot down by carrier-based fighters to the west of the transport area. A total of seven American planes were lost.33

The Naval Withdrawal

The burning of the Elliott had two adverse consequences, entirely apart from the loss of the ships herself. Included in the supplies aboard her had been a good shore of the material of the 2d Battalion, 1st Marines, and that was lost.34 The second, and more serious, consequence was the fact that the glare caused by her burning allowed enemy observers in the neighborhood of Tassafaronga to see the cruisers and destroyers which were shortly to be attacked on that night of 8-9 August, and to report their presence to the advancing enemy task force.

In the evening of 8 August, General Vandegrift

Ballance, USMC, wrote in 1949: Item "an elaborate air compressor plant" was actually a liquefaction plant for the manufacture of oxygen by compressing it to liquefaction and then "fractionally" distilling it. This plant would have provided compressed air for torpedoes as well as aviation, medicinal, and welding and cutting oxygen. The wanton destruction of this plant, then 70 to 75% complete, with remaining components on hand ready for installation was truly deplorable, for eventually just such a plant had to be hauled out from the United States and erected on the island.

was called to a conference aboard the USS McCawley, flagship of Task Force 62. While there he was told that Admiral Turner had decided to remove all transports and cargo vessels from the area at 0600 next morning, 9 August. The reason given for this decision was the fact that advice had come from Admiral Fletcher, Commander, Task Force 61, telling of a shortage of fuel and of the loss of 21 of his 99 planes, and of his consequent decision to withdraw.35

This posed a new and most alarming problem for General Vandegrift and his staff. Plans made by the division had been formulated on the assumption that the ships would remain for four days in the target area so that all supplies could be put ashore. however, even with the removal of all supplies to the beach, the division would have been in a somewhat precarious position, for the shortage of shipping and the unforeseen demand for haste had made necessary a cut below the basic allowances ordinarily prescribed. The unloading process, as we have seen, had been complicated by a condition approaching chaos on the beach, and the movement from ship to shore had been stopped as a result. The withdrawal of the supply ships, therefore, was, from a troop standpoint, little short of a catastrophe, but Admiral Turner's decision was not changed.

Shortly after midnight of 8-9 August, moreover, friendly surface forces operating in the Solomons area suffered a sudden and overwhelming defeat. The events leading up to the disastrous Battle of Savo Island are interesting.

There can be no doubt at this time that the American attack on Tulagi and on Guadalcanal came as a surprise to the enemy at Rabaul as well as to the smaller forces in the target area.

The American convoy had been sighted as it approached the area by an enemy lookout in the vicinity of Cape Esperance. There appears to have been a breakdown in communications between his post and Tulagi, for his warning did not alert the people on the latter island.36 The attack, moreover, cut the area off from communication with the enemy rear areas (the radio installations on Tulagi, Gavutu, and Tanambogo had been destroyed by the prelanding bombardment by the San Juan and the two destroyers which accompanied her). Captain Miyazaki, of the Imperial Japanese Navy, who was on duty at Rabaul at the time, was questioned on November, 1945, as a prisoner of war. He said, in speaking of the events of 7 August 1942, "Early in the day we lost communication with Gavutu, so did not know what happened."37


35. It has been widely believed that Admiral Fletcher's decision was reached on the spot late in the day of 8 August. This is not the case. A dispatch sent to Fletcher by Vice Admiral Ghormley on 2 August (after Callaghan had reported the gist of the Fiji conference) shows that even prior to that date Fletcher had planned to withdraw his task force, and therefore also the transports, before D-day plus three. Ghormley, not protesting, thereby gave tacit approval to Fletcher's plan to withdraw. War Diary, ComSoPac, 2 August. The division commander had no information that such a withdrawal was planned, the first indication of its coming to him as described above. Operation Plan 1-42 dated 16 July 1942, ComSoPac, had directed that all vessels fuel to capacity during the rehearsal at Fiji. Tankers used were the Platte and the Cimmaron each with 12,000 tons of fuel oil and 500,000 gallons of aviation gasoline, and the Kaskaskia, with 13,000 tons of oil. This order had been carried out at the conclusion of the exercises, immediately prior to departure fro the objective. War Diary, ComSoPac, June, 1942, contains the text of the plan.
When Fletcher, the man on the spot, informed me he had to withdraw for fuel, I approved. he knew his situation in detail; I did not." Ghormley ms. p. 93. According to data secured from ships' logs, every ship in Task Force 61 had on hand enough fuel when the log was closed on 8 August to last for at least four days. The carriers could have operated for 17 days, North Carolina for 18 days, the cruisers for about 11 days, and the destroyers, most voracious of the lot, for about seven days. These figures are based on the average daily consumption of each individual ship taken over the period of 1 to 8 August, 1942, and take into account the fact that two "short-legged" destroyers--Benham and Grayson--had fuel enough for three and two days respectively. Logs may be found in the National Archives.

VICTIM OF SAVO ISLAND, the heavy cruiser Astoria burned throughout the morning of 9 August 1942, until, engulfed by uncontrollable flames, she sank.

Communication must have been reestablished quickly, however, or else the enemy must have been able to deduce, from the silence that had fallen over its forces in the Tulagi area, that an attack had been mounted. By afternoon of 7 August a naval task force was being assembled from units in Kavieng and Rabaul.38 It was formed from elements of the 8th Fleet, and consisted of five heavy cruisers--Chokai (flying the flag of Rear Admiral Gunichi Mikawa, CinC, 8th Fleet), Kako, Furutaka, Aoba (Rear Admiral Goto), Kinugasa, the light cruiser Tenryu (Rear Admiral Matsuyama), and Yubari--with one old destroyer Yunagi from the 4th Destroyer Division. Rendezvous was effected northwest of Bougainville, and the force came down the stretch of water which lies between the parallel chains of islands of the group and which was later to become known as the "Slot".

This force was sighted at 1130 on the morning of 8 August by a U.S. observation plane which maintained contact with it for about an hour.39 The results of the observation were reported at once, but through some mixup in the communication chain which as never been satisfactorily explained, the screening force of United States and Australian ships apparently was not apprised of the potential danger which the enemy task force presented.40

The screening force, divided in two groups, was patrolling the approaches to the transport area on each side of Savo Island when, at about 0130 of the morning of 9 August, it was attacked and overwhelmingly defeated by an enemy force which immediately retired from the area. No attempt was made by the Japanese to pursue the advantage which had been gained, and the transport area was left unmolested. The attack had been preceded by the dropping of flares from Japanese cruiser-based planes, and information subsequently got from prisoners indicates that the attacking force was aided by observation from Cape Esperance made possible by the illumination from the flares and from the burning transport, Elliott.41

The results of the attack were little short of catastrophic for the Allied forces. Of the five cruisers on station at the time, four were sunk and the other badly damaged. Chicago sustained damage, while Astoria, Vincennes, Canberra, and Quincy sank during the night and the early morning.42

Post-war interrogation of Japanese prisoners answered a question which arose immediately after the Japanese withdrawal--why had the attacking force refrained from annihilating the then defenseless transports? It appears that one 8-inch round fired from the second group to be attacked--the Northern Group--penetrated the operations room of Chokai, destroying all equipment and charts.43 This together with the fact that there was some delay in resuming proper formation, impelled Vice Admiral Mikawa to withdraw rather than run the risk of being overtaken by planes during a later withdrawal.

A belated vengeance overtook another ship of the force when Kako, about to enter the harbor of Kavieng the next morning, was sunk off Simberi Island by an American submarine, the old S-44.44

Withdrawal of Task Force 62

There is no evidence to show that the proximity of the enemy task force had any bearing upon the decision of the Commander of Task Force 62 to retire, although the position, speed, and direction of the enemy group were known to him prior to his conference with General Vandegrift. The exact composition of the force was not known, and the enemy's intentions were not accurately estimated.45

According to the War Diary of the Commander, Task Force 62, the following troops were left in the Guadalcanal-Tulagi area when the transports and supply ships withdrew:

At Guadalcanal:

Division Headquarters Company, less detachments
Division Signal Company, less detachments
5th Marines (less 2d Bn.)
1st Marines
11th Marines (less E Battery, and the 1st and 4th Bns.)
1st Tank Bn., less detachments
1st Engineer Bn., less detachments
1st Pioneer Bn., less detachments
1st Amphibian Tractor Bn., less detachments
1st Service Bn., less detachments
1st Medical Bn., less detachments
1st Military Police Co.
2d Platoon, 1st Scout Co.
Local Naval Defense Force
Total on Guadalcanal, about 10,000

At Tulagi:

Battery E, 11th Marines
Company C, 2d Service Bn.

Total on Tulagi, 6,075

Total personnel left in area, about 16,075

The 2d Marines, under Colonel John M. Arthur, had formed the Division Reserve, and had, as a part of its ultimate mission, the occupation of Ndeni, in the Santa Cruz Islands.

As we have seen all three battalions of the regiment were committed. This was done by orders from Rupertus direct to the battalion

commander in each case and not through the normal chain of command.46 The regimental headquarters remained afloat, however, as did all administrative personnel and all records of the regiment and its battalions. In addition to these, working parties from all companies, as well as most of the Headquarters and Service Company, Regimental Weapons Company, and G and Headquarters and Service Batteries, 3d Battalion, 10th Marines, remained aboard ships.

When the transports left the area on 9 August, this group (which totaled 1390 officers and men) were taken, in Transport Divisions 2 and 12, to Espiritu Santo, where, according to the War Diary of Commander, Task Force 62, they were used to "reinforce the garrison there." On 14 August, Colonel Arthur was ordered by Admiral Turner to report to the Commanding General, Espiritu Santo, for duty. He did so, but within a few days he was ordered to return to Tulagi with a small number of officers and men of his command.47

A good-sized complement of Marines was left on Espiritu Santo, however, for elements of the 2d Marines were subsequently ordered by Admiral Turner to form a "2d Provisional Raider Battalion", to consist of a small headquarters and six rifle companies. This was done, but the unit was disbanded on 22 September, two days after arrival of the authentic 2d Raider Battalion, under Lieutenant Colonel Evans F. Carlson. Eight hundred men of the 2d Marines and Battery G, 10th Marines, were then ordered to return to Tulagi. They arrived 9 October with 358 men of the 6th Naval Construction Battalion.

The forming of the "2d Provisional Raider Battalion" gave rise to a considerable correspondence by Admirals Turner, Ghormley, and Nimitz, and the Commandant of the Marine Corps, General Holcomb.

It will be recalled that General Vandegrift was operating under immediate command of Admiral Turner, Commander Amphibious Force, South Pacific. In a letter written to ComSoPac on 29 August, Turner said in part:

6. In many circumstances in the future amphibious warfare in the South Pacific, it is believed that a Marine Regiment, or a part of a Marine Regiment, or two Marine Regiments, will be the size of a force appropriate for offensive and defensive amphibious operations. The employment of a division seems less likely. .  .  . The problem of mopping up outlying detachments will exist throughout the campaign. For this reason the Commander, Amphibious Force, South Pacific, has reached the conclusion the Marine regiment (sic) will not be an entirely suitable combat unit for operations in the South Pacific unless it has, as an integral part of its organization, either a Raider or a Parachute Battalion. The previous concept that Raider and Parachute Battalions are always division or corps troops is no longer agreed to.

7. In view of foregoing, and in order to prosecute promptly the operations required by prospective tactical situations, the Commander Amphibious Force, South Pacific, will, unless directed to the contrary, proceed with the organization of Provisional Raider Battalions in the Second, Seventh and Eight Marines, and give these already trained troops such additional specialized training as seems appropriate. Furthermore, he recommends that Marine Corps Headquarters issue directions for the permanent organization of Raider Battalions as integral units of all Marine regiments now attached to, or ultimately destined for, the Amphibious Force, South Pacific. It is not recommended that the total personnel strength of the regiments be increased.

Vice Admiral Ghormley forwarded the letter to Commandant Marine Corps on 6 September, via Commander in Chief, U.S. Pacific Fleet, with his own reactions to Turner's suggestions attached in the form of a first endorsement:

The organization of Raider Battalions from the organic troops of the 7th and 8th Marines should be withheld pending a declaration of policy by the Commandant, Marine Corps. .  .  .

A copy of this endorsement was sent to Turner.

Admiral Nimitz, in turn, added a second endorsement, also directed to General Holcomb, on 24 September:

The Commander in Chief, U.S. Pacific Fleet is of the opinion that Raider Battalions are specialized troops and should be reserved for appropriate tasks--and that extemporized organization of Marine Forces should be made only in case of dire necessity.


46. Interview, Colonel R.E. Hill.
47. War Diary CTF 62. September and October, 1942.


This correspondence elicited the following reply on 3 October from General Holcomb, in the form of a letter to Nimitz:

The Commandant noted with much concern the order from the Commander, Amphibious Force, South Pacific Force, to organize a raider battalion, on a temporary basis from the units of the 2d Marines, less its battalions. He made no comment at the time for reason that at this distance no one could form an opinion as to the necessity of carrying out this most unusual procedure. The objections thereto are clearly set forth by the Commander-in-Chief, U.S. Pacific Fleet, and appear to need no further comment. .  .  . It is noted with regret that Admiral Turner's letter of August 29th does not contain the views of the Commanding General, 1st Marine Division, in a matter in which he is particularly qualified and concerned.


Chapter IV: Establishment of the Perimeter and Battle of the Tenaru

THE EXISTENCE OF THE FLEET MARINE FORCE in 1942, together with the leadership and amphibious technique it had produced, made Guadalcanal possible. This picture, taken in August 1942, shows the Marine leaders who launched the campaign, including t...

By Sundown 9 August, all ships had cleared the area, and the Marines were left with inadequate supplies, no idea as to when that condition would be ameliorated, and very meager intelligence of the enemy forces on the island. Task Force 61, whose planes had done yeoman service during the fist two days, had withdrawn, and the remnants of the cruiser force which had patrolled the western approaches to the island had been forced to leave the vicinity.

Because the force at his command was a relatively small one, General Vandegrift decided that every emphasis be placed on


defense of the Lunga point region, including the all-important airfield.1

The defense itself would be centered on the field, with the strongest positions of the perimeter placed along the beach proper as a precaution against counter-landings. This sector was organized in two regimental subsectors. Automatic weapons were sited for water's edge defense. Thirty caliber machine guns were set up so that their final protective lines would lie along the actual edge of the beach. The heavier weapons, .50 caliber machine guns and 37mm guns, were so emplaced as to be able to deliver antiboat fire. Emplacements were dug some distance back of the beach for the half-track 75mm, but the weapons themselves were kept mobile in readiness for movement forward to other prepared positions near the water's edge.2

Infantry was assigned the task of protecting these weapons emplacements and was scattered in foxholes along the line. The larger part of the force, however, was kept within the perimeter, ready to move in any direction to deal with possible penetration of the lines, as well as for counter-attacks at the proper time. Mortars in general were retained in the rear of their respective battalion positions, while the artillery, 75s and 105s of the 11th Marines, was grouped well inland to the south of the airfield in such position that it could be used for the defense of any threatened sector of the perimeter.

The entire defense area was generally in the shape of a long, flat oval with the long axis running in an east-west direction. One curve lay along the beach where there was no natural defense save the water itself. The right, or east portion, of the perimeter was bounded by Alligator Creek, a sluggish, deep stream. Such was the character of the land through which it flowed, and of the banks and the undergrowth along the, that it formed an admirable defensive position, and on e of which full advantage was to be taken in the first land action of the campaign. The left bank of this river was used as a line for the extension inland of the right flank. Machine gun emplacements were constructed at the

BEACH DEFENSES were hastily established with such meager materials as had been left by the retiring transports. Japanese counter-landing behind the Marine perimeter was a constant threat during early days of the campaign.

only point where crossing seemed feasible--at the very mouth of the river, where, at low tide and during dry weather, a sand bar permitted foot passage from bank to bank along the beach.

The left or west flank of the perimeter had no such naturally advantageous terrain upon which to depend. Westward of the mouth of the Lunga, there is a re-entrant in the coast, a long sweeping concave curve toward the Matanikau River, four miles away. At a point midway between the two rivers, the grassy ridges, which are the outward boundary of the rough country of the interior, impinge suddenly upon the coastal plain, and the latter is reduced to a narrow corridor several hundred yards wide, between the beach and the hills. In this terrain, the coconut palms disappear and are replaced by lowland jungle. Passage through the region, save by the coastal road, is difficult. It was decided to anchor the left flank on this higher ground and extend the lines from the beach and across the narrowing coastal plain on the theory that the knolls could be used to an advantage in dominating the corridor.

Between the inland extremities of each flank extension lay a chaotic jumble of ridges, ravines, and flat jungle country. It was impossible to establish a continuous line across such terrain even had there been sufficient Marines for the task. The alternative to such a defense was to dispose various units in compact areas along the general defensive line and maintain contact and security by a system of out-posts. It was realized that any attack from inland could result in a penetration of the perimeter, but such a disposition of troops would permit the various unit sectors to be defended separately, so that the normally disruptive effect of penetration would be minimized.3 This was supplemented by the practice of sending patrols inland for about 1500 yards. These patrols in general were formed from units defending inland sectors.

The enemy struck back quickly as a result of the stimulus of American attack. Low-level bombing attacks were frequent and effective, both against the troops and the engineers who were struggling to finish the partially completed air strip. The initial effectiveness of these attack was lessened when the antiaircraft group of the 3d Defense Battalion succeeded in emplacing one battery of four 90mm guns on the periphery of the airfield.4 The attacks, however, continued into the following year, becoming sporadic after 15 November.

Enemy surface craft meanwhile enjoyed practically undisputed possession of the waters adjacent to Guadalcanal during the period 9-20 August. Shelling by submarine, as well as by larger craft, became a regular occurrence, causing relatively minor damage to shore installations, but seriously impeding operations of small craft back and forth to Tulagi.5

An all-out offensive on the part of the Marine forces was out of the question. Only a part of the reinforced division was in the perimeter, and even that small part was, logistically, in a precarious position.6 The area which it had occupied and which it was prepared to defend was but a tiny fragment of the total surface of the island.

Of the several possible methods of obtaining information to supplement the existing scanty knowledge, only one ultimately proved to be useful, patrolling. Aerial observation,

6. Some of the idea of the supply situation can be obtained from a message sent by the Assistant Division Commander on 10 August at 0902 when the last of the transports had left the area and when all available supplies had been landed. The message said that the situation was changing. It requested entrenching tools, sandbags, barbed wire, diesel oil, and TBX (radio) batteries, saying that none of these materials had been landed. Final Report, Phase III, p. 5.


even had there been planes to carry it out, would have been of limited usefulness. The heavily wooded areas of the island provided overhead cover for ground troops under which they could operate with almost perfect freedom from discovery. Aerial photographs were subject to almost the same limitations as direct aerial observation.

The information received from observation posts likewise was largely negative in character. The same natural peculiarities that operated against adequate aerial observation on the first and second days of the campaign also operated to prevent any appreciable amount of information being obtained visually from fixed posts. Once more, it is necessary to point out that, save along the coastal plain in the vicinity of the coconut groves and the coastal road, the terrain is characterized by precipitous ridges running in every direction and separated by deep, narrow ravines. Visibility from observation posts in country of this type is extremely limited, and the negative character of information to be obtained from them is by no means as indicative or as valuable as similar information obtained from similar posts in open or flat country.

Third method of obtaining information, and the one which was actually used by the Marine forces, was that of patrolling.7 Each regiment in the perimeter including the 11th Marines was assigned certain areas outside the perimeter for such operations. Patrols of varying size were sent out daily and in general operated between the hours of 0700 and 1800.

Patrolling on the first two days of the campaign was somewhat characterized by over-caution and lack of aggressiveness, but these faults were overcome eventually. On 9 August, a 4th Marines patrol operating several miles southwest of the Kukum sector of the perimeter met a heavily armed enemy patrol in the first definite encounter with enemy forces. A small action resulted, and unspecified casualties were suffered by both parties. Again on 10 August, a similar patrol also from the 5th Marines operating still farther afield, and attempting to cross the Matanikau River at its mouth, was denied that crossing by a strong, well armed, and apparently well-emplaced enemy force on the west bank. Similar patrols operating in the opposite direction to the southeast of the perimeter had as yet made no contact with enemy forces.

The information so obtained indicated that the nearest enemy force was somewhere west of the perimeter. The negative information, on the other hand, while it by no means ruled out the possibility of other forces to the southeast, showed at least that patrol activity could be pushed farther afield in that direction.8

The Goettge Patrol

These considerations led to the organizing of two patrols, each of which exerted a profound effect on the early progress of the campaign, although those effects were diametrically opposed to each other. The first, which was the result of faulty planning and a lack of appreciation of the basic theories of patrolling, caused a serious loss to the division staff, as is hereinafter described.

The necessity for gaining more exact information regarding enemy forces near the Matanikau impelled the division intelligence section to lay tentative plans for a thorough reconnaissance of the territory.9

The initial plan, as far as it is possible to reconstruct it, seems to have been sound. A sortie was to be made by boat from Kukum in the early morning and a landing made on the beach near Point Cruz. The patrol, having

The details obtained from those sources have been elaborated on the basis of accounts given the compiler by officers and men present on the island at the time--Colonel (now Brigadier General) Gerald C. Thomas, Lieutenant Colonel (now Colonel) Edmund J. Buckley, who replaced Goettge as D-2, First Lieutenant (now Captain) John J. Jachym, and others.


landed, was to make its way up the left bank of the Matanikau River, making careful observation of the terrain, and establish a bivouac for the night as far back in the hills as time would allow. The second day was to be spent in a cross country return to the perimeter. The patrol was to b e large enough to permit combat if the occasion demanded.

According to an officer present at the time, Lieutenant Colonel Goettge, Division Intelligence Officer, was already committed to accompany a patrol toward Tetere, which will be described below, when he was advised of the tentative plans of the Matanikau operation. He immediately assumed personal charge of the project, and, in view of two bits of information that had recently come to him, decided upon several radical changes in plans.

A naval warrant officer had been taken prisoner in the vicinity of Kukum, behind the lines of the 1st Battalion, 5th Marines.10 Subjected to routine questioning by regimental and divisional language officers, he had said that it was possible that some of his fellows to the west might be persuaded to surrender under certain conditions. The information he gave was such as to place the group somewhere in the general area of the proposed patrol. The second item of information was the reported appearance of a white flag, seen by a patrol on 12 August, also in the area the patrol was to cover. This was taken as further evidence that the enemy in that neighborhood desired to surrender.

There was no reason to doubt the sincerity of the prisoner. He was reticent and did not volunteer information, and it was only after considerable questioning that he agreed to the possibility of the surrender. Moreover, it is probable that the putative white flag of surrender was an ordinary Japanese battle flag flying so far from the observers that the red center was not visible.11

FIRST PLANE TO LAND on Henderson Field was a Navy PBY-5A which evacuated two wounded Marines on 12 August 1942.

The original plan called for an early start so that the landing could be made by daylight and ample time could be available for reconnaissance before going into bivouac. Colonel Goettge, however, had introduced additional details that caused almost twelve hours' delay. He was convinced that many noncombatant Japanese were wandering through the jungle in starving and disorganized groups and that every effort should be made to enable them to surrender. This humane attitude caused him to alter the composition of the proposed patrol to include, among others, the 5th Marines' surgeon, Lieutenant Commander Malcolm L. Pratt, and Lieutenant Ralph Cory, a Japanese linguist. A large part of the intelligence section of the 5th Marines likewise was taken, and, since the patrol as it was finally organized, contained only 25 persons, it seems obvious that one result of the last-minute changes had been to reduce the combat effectiveness of the group.

As a result of these changes, the patrol did not depart from the perimeter until 1800 on 12 August,12 and the landing, of course, was made after dark, at about 2200. As far as can be determined at this time, Goettge planned to land the group west of Point Cruz. On the day of departure he had been warned specifically against attempting to land between the

12. Final Report, Phase II, p. 6. Another important, and happier event took place on 12 August. The first American plane to use the newly won air strip landed and took off with two wounded Marines--a method of evacuation that was to be used throughout the campaign with outstanding success. The plane was a PBY-5A, number 05045, and was piloted by Lieutenant W.S. Sampson, USN. Ibid., Annex B, p. 2.


mouth of the Matanikau River and the point, for a patrol action three days before had established beyond question the fact that strong enemy positions commanded that area.13

As a matter of fact, the landing was made on the very beach against which Goettge had been warned--darkness and lack of familiarity with the terrain led to the error. The patrol got ashore without difficulty and the landing craft withdrew. As the men began working their way inland, however, they were taken under intense fire at once from rifles and machine guns, and by shortly after midnight the group, with the exception of three men sent out to report the event, was wiped out.

The three survivors arrived at intervals of about an hour, beginning at 0530 on 13 August. At that time Sergeant Charles C. Arndt came to the perimeter with the news that the patrol had encountered the enemy immediately after landing. He had been sent back at 2230. A relief patrol (Company A, 5th Marines) was sent out immediately by boat. As it made its way up the coast, the two other survivors came in--Corporal Joseph Spaulding at 0725 and Platoon Sergeant Frank L. Few at 0800. They brought work of the wiping out of the party.14

Company A, meanwhile, landed west of Point Cruz, at what was thought to be the scene of the Goettge landing. After receiving a reinforcement in the form of two platoons of Company L, 5th Marines, and a light machine gun section, the group began moving east, toward the perimeter. Company A, coming along the coastal road, encountered minor resistance from enemy emplacements near the mouth of the Matanikau. It returned to the perimeter late in the evening of 13 August. Company L, with its attached light machine gun section, followed a route lying farther inland, and arrived at midday on 14 August, having been held back by difficult terrain.15 Neither group found traces of the patrol.16

First Action along the Matanikau

On 19 August, the day which saw an important patrol action near Tetere to the east, as will be described, the first planned offensive beyond the perimeter was carried out. The fate of the Goettge patrol, and the data secured by the group which went in search of it, confirmed what had been surmised--that the enemy was in reasonably strong positions in the territory just west of the Matanikau River. It was, therefore, planned to attack and destroy the force.

The operation set the pattern for several attacks in the future, attacks which were to enjoy varying degrees of success. The assault was to be in the form of a three-pronged attack, supported by fires from the 2d, 3d, and 5th Battalions, 11th Marines, division artillery regiment.

Company B, 5th Marines, from a position at the mouth of the river, was to attack westward, across the river, while Company L, 5th Marines, after crossing the river far upstream at 0800 on 18 August and cutting its way toward the mouth along the left bank, was to attack the area from inland on 19 August. Company I, in the meanwhile, after traveling by boat from the perimeter on 19 August to the small village of Kokumbona, which lay several miles to the west of Matanikau, was to cut off the retreat of the enemy to the west and clear out the village itself.17

The attack was partially successful. Company

of keeping the enemy active and alert on one front while an attack against his right flank was developing from inland. Company I, traveling by boat, was shelled enroute by two enemy destroyers and one cruiser standing far out. No casualties resulted from this attack, although several near misses fell among the boats. The enemy craft remained all morning, finally being driven off by two B-17s.18 Fire from light machine guns on the beach was encountered. Resistance was met after the company landed, but the village was assaulted with inconclusive results, the enemy retreating into the hills with all weapons instead of making a stand. All companies returned to the perimeter, having inflicted losses in excess of 65 killed, and an unknown number wounded, on the enemy, while suffering the comparatively small loss of four killed and 11 wounded.

The Brush Patrol

The second patrol, and the one which ultimately was the more important from a combat standpoint, had a curious origin. The area assigned to the 1st Marines for patrolling and reconnaissance lay east and southeast of the perimeter. The plains in the vicinity of the Lunga widen out to the eastward, so that near Tetere, for instance, there is a belt of grassy land nearly eight miles wide. It had been known for some time that it was possible to build an airfield there--at one time there was suspicion that the Japanese were actually engaged in building one--and that there was a plan to proceed with initial surveying of the district preparatory to such construction.

On 12 August, a group of engineers set out from the perimeter with the mission of beginning that survey, and accompanying them, for purposes of security, was one platoon of Company A, 1st Marines, under command of Second Lieutenant John J. Jachym. On 13 August, while the group was passing through a small native village, it was greeted by a young Catholic priest, Arthur C. Duhamel of Methuen, Massachusetts. He said that there were rumors of an enemy force farther to the east, along the coast.19 No definite details could be obtained, and in view of the nature of the information, Lieutenant Jachym decided to return to the perimeter, report the news, and, if necessary, return with a larger body to verify it.

Two days later, a partial verification of Duhamel's advice was made by Captain W.F.M. Clemens, a coastwatcher and former official in the British Solomon Islands Civil Government. Accompanied by Sergeant Major


18. Letter, LtCol W.H. Barba to Commandant Marine Corps, 28 January 1948. The cruiser was fired upon by the 1st Platoon, Company M, 5th Marines, under 2dLt Drew Barrett, using two captured 3-inch dual purpose naval guns. The platoon fired 20 rounds, all short. The cruiser bracketed the position with a starboard salvo, but there were no casualties.
19. He probably referred to the Japanese coastwatcher station at Taivu, set up in June or July by Yoshimoto. That small group continued to operate until some time in October.


Vouza20 and several other natives, Clemens arrived at the command post on 14 August, and reported that he had received news of an enemy radio station near Taivu. On the same day, Admiral Turner advised Vandegrift that the Japanese were planning an attack in force on the perimeter.21

At 0700 on 19 August, therefore, the patrol was formed and set out toward Tetere. It consisted this time of a part of Company A, 1st Marines, and was led by Captain Charles H. Brush. Its route lay along the coastal road that leads from the Lunga to the Koli Point-Tetere area. By noon the group had come to a small village, and Captain Brush ordered a halt there for food and for a short respite from the heat. Someone recalled, however, that, a short distance farther along the road, there was said to be a grove of fruit trees, and, with the idea of securing this supplement to the meager canned rations, the company took to the road once more.22

Midway between the two villages, the scouts preceding the main body caught sight of a group of Japanese traveling westward between the road and the beach. The group consisted of four officers and 30 men, not in military formation. Brush's patrol attacked frontally with part of its strength, with an enveloping movement of one platoon, led by Jachym, around the right flank. Fifty-five minutes of action resulted in the wiping out of the enemy force--31 of them were killed, and three escaped into the jungle. The Marine patrol lost three killed and three wounded.

An inspection of the dead revealed a number of interesting details. There was an inordinate amount of rank, for one thing, and there was the additional fact that when it had been surprised by Brush's patrol, the enemy group had been at work laying communication wire--an almost certain indication of the presence or expected early arrival of a much larger force.

A further, and more immediately disturbing detail, was that of the nature of some of the documentary material found with the bodies. Major (then Captain) Brush has the following remarks to make:

With a complete lack of knowledge of Japanese on my part, the maps the Japanese had of our positions were so clear as to startle me. They showed our weak spots all too clearly. For example, the First Battalion, First Marines, had been preparing positions on the right of the Second Battalion, but were not occupying these positions. On the right of the First Battalion there was nothing. This fact was clearly shown on the Japanese map which I inspected on the scene of the patrol action.23

Subsequent translation of the documents, which were rushed back to the perimeter by runner at once, confirmed the impression made upon Brush--that the enemy group was the advance party of a much larger force.

Beginning of Air Support

It was realized that a successful defense of the island, and a consequent denial of that island to the enemy, depended directly upon the ability of the Marines, to develop and use the airfield.24 Until the field was completed and fighter and dove bomber planes brought in, the Division would continue to be at the mercy of any air or naval attack that the enemy cared to deliver.

The 13 days which elapsed between the landing and the arrival of the first combat planes were marked by daily air raids as well as by attacks from surface craft, submarines,

destroyers, and, from time to time, cruisers. Defenses against these attacks were scanty and ineffective. The antiaircraft weapons emplaced around the airfield by the 3d Defense Battalion succeeded only in keeping the attacking planes at a reasonably high altitude. Enemy bombing was fairly accurate even from the 25,000 feet level.25 There were occasions on which 75mm half-tracks succeeded in driving off enemy submarines.26

A survey of the airfield conducted on 8 August revealed the fact that about 2,600 feet of the runway, which was 160 feet wide, could be completed within two days and that the remaining stretch of approximately 1,178 feet could be made ready for use within a week.27 Actual construction was begun the next day, 9 August, when the 1st Engineer Battalion began operating. Supply and equipment, however, were at a premium. It is estimated that Fomalhaut, carrying most of the earth moving equipment, departed when only 15 percent of her cargo had been discharged.28

The withdrawal of the transports had left the Marine forces with only a part of their initially scanty supplies ashore. Ammunition supply was adequate, but the situation in the matter of food was serious. Even with the acquisition of a considerable stock of rice and canned food from the captured Japanese area,29 supplies were so short that it was necessary on 12 August to begin a program of two meals per day. There was a similar shortage of defensive material, barbed wire (of which only 18 spools were landed), and entrenching tools and sand-bags.

The most serious shortage of all, however, from the point of view of the engineers who were charged with the completion of the airfield, was that of specialized equipment necessary for the task. No power shovels had been landed, nor dump trucks. One bulldozer,

property of the Pioneer Battalion, had come ashore, but was not immediately available for work on the airstrip.30 Here again, however, good fortune played a deciding role, for it was found that the Japanese equipment which had been landed for the purpose of constructing an airfield was largely undamaged and usable, although antiquated.

Concurrently with the establishment of the perimeter, the strenuous efforts of the under-equipped engineers, and the probing patrol activities of the rifle regiments, a new and significant phase of the campaign began. The first elements of Marine Corps aviation began moving toward the island.

On 12 August, the USS Long Island, with VMF-223 and VMSB-232--Marine fighter squadron and dive bomber squadron respectively--was about to depart from Suva, where she had taken refuge upon receipt of the news of the Battle of Savo. She was expected to arrive in position to fly off the planes of the two squadrons about 16 August.

The ground echelon of Marine Air Group (MAG) 23, however, was embarked on the USS William Ward Burroughs, which was not scheduled to arrive at Guadalcanal until 19 or 20 August. This circumstance would create a problem, for although there was some aviation gasoline at the newly completed airfield--400 drums of fuel which the Japanese had stocked in anticipation of the scheduled arrival of their own planes on 7 August--the absence of trained ground crews would make it impossible to operate the fighters and dive bombers.

Admiral McCain (CTF 63 and COMAIRSOPAC) found his way out of this dilemma, thanks to the presence of CUB-1 at Espiritu Santo. On 13 August he ordered Major C.H. Hayes, executive officer of VMO-251, to proceed to Guadalcanal with the aviation component of this unit in order to provide ground facilities for the squadrons when they landed. Hayes accordingly alerted the senior naval officer of the CUB--Ensign George W. Polk31 - and prepared to embark his detail.

The embarkation of the five officers and 118 navy enlisted was strangely reminiscent of the embarkation of the 1st Division. Recently arrived, the unit had only begun to unload its gear when, shortly before noon on the 13th, it was notified that it would embark that night and sail at once for Guadalcanal. It would use the four destroyer transports of Transdiv 12 for the movement.

This posed the problem of space upon that of transfer of cargo. Each APD could receive only 30 tons of cargo. Essential material only could be taken, much of which was either difficult of access or entirely unreachable in the holds of the ships which had brought it. The total supply carried northward by the four craft included as principle items 400 drums of aviation gasoline, 32 drums of aviation lubricant, 282 bombs ranging from 100 to 500 pounds, belted ammunition, and miscellaneous critically important tools and parts. The men carried light packs and arms only--it was thought that rations, mess and organizational equipment, medical supplies, and tentage could be supplied by the 1st Division quartermaster.

Hayes was briefed hurriedly by McCain


30. Letter, LtCol Henry H. Crockett to Commandant Marine Corps, 10 June 1949. This lone bulldozer was eulogized long after the war by Colonel Ballance, already quoted above. In the matter of this piece of equipment, he has the following eloquent passage in his letter to the Commandant dated 12 February 1949:

One R-4 bulldozer - actually an angle-dozer--was landed by the 1st Pioneer Battalion, and the yeoman service performed by this lone piece of power equipment in the hands of one Corporal Cates, its skilled proprietor - no one else was allowed to operate it--seems worthy of a place in the record. Cates drove that dozer from morning till night, he automatically ceased whatever task he was performing when condition RED sounded and headed for the airfield ready to fill bomb craters on the strip. He buried dead Japs, worked the roads and prepared bridge bank seats, cleared the Kukum beach for unloading operations, pulled, tugged, and towed all manner of things. That lovely R-4 finally fell apart like the one hoss shay, never to run again, some time in late October.

prior to setting out. His instructions directed him to expedite completion of the airfield (General Vandegrift had already declared it to be usable by fighter planes), prepare camouflage or concealment for the planes with particular attention to concealment for the SBDs, and provide ground service for the incoming aircraft until the arrival of the regular ground crews.32 His last act before going aboard was to conduct a frantic--and successful--search for chamois to be used in straining fuel from drums. This indispensable material he carried aboard under his arm.

The APDs departed on schedule, arriving off Kukum after dark on 15 August. Passengers and supplies were put on the beach, and next day CUB-1 took over from the 1st Engineering Battalion its share of the task of making ready the field.33

By 19 August, in spite of daily raids by enemy aircraft, work on the airstrip was completed, and the field was ready to receive the planes which arrived the next day.34

On 20 August, from a point 200 miles south of the island 19 planes of VMF-223 (F4F-4s led by Major John L. Smith) and 12 dive bombers of VMSB-232 (SBD-3s under Lieutenant Colonel Richard C. Mangrum) took off from the flight deck of the Long Island. Beginning at 1330, the flight ended with the safe arrival of all planes at Henderson Field35 at 1700.36 Within eight hours of their arrival the first great counterattack of the Japanese was thrown back, and within 12 hours the newly arrived planes were performing their first mission in support of the ground troops--patrolling the beaches east of the Tenaru to cut off any attempt at escape by the remnants of the enemy force which Pollock's 2d Battalion, 1st Marines had cut to pieces at the mouth of Alligator Creek (the "Tenaru").37

The Marine planes were followed, on 22 and 27 August, by elements of the 67th Fighter Squadron, Army Air Force. These 14 planes were P-40s, inadequate machines that could not do justice to the degree of training and spirit of their pilots. Unable to attain, and operate at, sufficient altitude, they eventually undertook close-support missions.38

Battle of the Tenaru

Presence of enemy forces to both the east and the west had now been established, and an attack upon the perimeter was inevitable. The problem remained of how best to prepare to meet such an attack.

The Lunga defenses had already assumed the basic form which they were to retain throughout the campaign, but, within the period of the past week, a considerable amount of improvement had been effected. The defenses on the east or right flank, as we have seen, were formed along the west bank of Alligator Creek. This flank extension had been lengthened to about 3,000 yards.39 It was planned to clear off the terrain by burning and by cutting, and to construct permanent fortifications, but there had not been sufficient time for such development.

General Vandegrift now had five rifle battalions available for manning the defenses. The entire 1st Marines was present, but the 5th Marines still lacked its 2d Battalion, which had been detached prior to D-day to the Assistant Division Commander for service on Tulagi. Of the available battalions, four

were committed to beach defenses and one was held in reserve.

Being reasonably certain of the existence of a Japanese force to the east, the Division Commander found two possible courses of action open. The first of these, which consisted of sending the single reserve battalion (1st Battalion, 1st Marines) eastward to met and destroy the enemy was rejected almost at once, since it depended upon the accuracy of the premises that the enemy had already landed and could be dealt with by one battalion. Also, there was no assurance whatever that the Japanese would not attempt an assault from the westward, a direct frontal assault, or indeed a combination of the two. Such a contingency would require the presence within the perimeter of every Marine capable of bearing arms.

The second course, which was actually adopted, consisted of strengthening all defenses in every way possible to a force which was inadequately equipped with defensive materials, and to institute and continue an intensive program of patrolling in the direction whence it was expected an attack would be launched. In this way, it was hoped, the hostile forces could be located, fixed, and their intentions more precisely divined.

Implementation of this program was begun at once. Native scouts operating under the direction of Captain Clemens assisted the Marine forces in active patrolling as far east as the Nalimbiu River. Day observation posts were set up in the vicinity of the Tenaru. The latter were withdrawn by night and in their place a system of listening posts was established in the neighborhood of the Tenaru and a small stream closer to the perimeter, known as the Block Four River.40

A study of enemy documents which was begun during the Guadalcanal campaign and carried on for many months after the close of the campaign, indicates that the attack on Guadalcanal by the Marines had caused serious disruption of Japanese plans.41 It appears that such plans envisaged a two-Army attack on Port Moresby in southeastern New Guinea. The attack was to be mounted from Davao in the southern Philippines and was to be carried out by the 17th and 18th Armies. The unexpected Fleet Marine Force landing upon Guadalcanal, however, caused the enemy to withdraw from their projected assault the 17th Army (less one division). This weakened army was thereupon earmarked for an attack upon the newly established Marine positions.

The first large Japanese reinforcement to reach Guadalcanal consisted of approximately one reinforced battalion of the 28th Infantry Regiment, a 7th Division unit, under the command of Colonel Kiyono Ichiki. This force, which had been detached for duty with the Imperial Navy in the attempted but unsuccessful occupation of Midway, was returning to Japan for rehabilitation on 7 August. Orders from Lieutenant General Hyakutake, commanding general of the 17th Army, intercepted the unit and brought it to Truk, where it arrived on 12 August. There it received orders to embark, pass to Guadalcanal, assault and retake the area held by the 1st Marine Division.42

Accordingly, Ichiki embarked his battalion reinforced by engineers and artillery on six new destroyers - Arashi, Hagikaze, Hamakaze, Tamikaze, Urukaze, and Kagero. The force passed down to me island without incident, and landed near Taivu on 18 August.43

Ichiki then sent out a reconnaissance party to explore the territory lying between the point of landing and the Marine positions.44 This patrol, as we have seen, was intercepted and wiped out by Captain Brush's patrol on 19 August.

Midnight of 20 August found the 1st Marines in position around the right flank of the perimeter, with the 2d Battalion in the crucial position at the mouth of the river, its right flank extending several hundred yards up-stream. The 3d Battalion, on the left of the 2d, held the beach line from that point to the mouth of the Lunga, while the 1st Battalion, not in prepared positions, was located to the right rear of the 2d Battalion, in division reserve. Listening posts from the 2d Battalion were established in the territory forward of the lines.

Some time after midnight45 these forward elements began falling back on the main positions, bringing word that there appeared to be a rather large enemy force in the neighborhood of the Tenaru River. Flares had been seen, and sounds of movement of men had been heard, but no visual contact with the enemy body had been made.

At about the same time, a dramatic confirmation of the presence of enemy to the eastward occurred when Sergeant Major Vouza (retired) of the Native Constabulary appeared, badly wounded, at the command post of the 2d Battalion, 1st Marines. He had been caught by the Japanese on 18 August in his village several miles to the east of the perimeter. When he refused to give them information, he was tortured and left for dead. He made his way, at night, through the enemy force and arrived at the mouth of Alligator Creek in time to tell Lieutenant Colonel Edwin A. Pollock, the battalion commander, of its presence.46

Vouza's own account of his capture has epic qualities. The following extract is from a letter written by Vouza to Hector MacQuarrie, who had known him during the early 1920s:

Well, I was caughted by the Japs and one of the Japanese Naval Officer questioned me but I was refuse to answer & I was bayoneted by a long sword twice on my chest, through my throught, a cutted the side of my tongue & I was got up from the enemies & walked through the American front line & there my Officer Mr. Clemens who D.C. at Guadalcanal during the War, later he is Major & his Clerk a native from New Georgia he was Staff Sgt his name was Daniel Pule. Both got the reports information from the Marine Division at the Front Line by one of the Colonial of the American Marine Div, his name was Col. Buckley that I was wounded. So then boths Major Clemens & Staff Sgt. Daniel Pule they came up to the front line & took me to the American Hospital at Lunga Guadalcanal & there they done the treatment and the wounded was healthed up, only 12 days I was in Hospital.

No serious apprehension seems to have been felt by Colonel Cates, the regimental commander at this news of enemy activity.48 At about 0300, however, a sentry posted on the west bank of Alligator Creek--then believed to be the Tenaru River--heard sounds of motion on the far bank of the river. He challenged, and, when there was no answer, he fired.

By this time Colonel Ichiki had assembled his force in positions on the narrowing point of land on the right bank of the river. At 0310 there was a sudden and violent attack by a group of approximately 200 Japanese, who rushed the sand bar at the mouth of the stream in a column.49 In site of the concentrated fire from rifles, emplaced machine guns, and cannister-firing 37mm cannon, and in spite of the extremely heavy casualties immediately inflicted upon them, a part of the group succeeded in gaining the left bank and in overrunning a few emplacements. A quick counterattack by Company G, 1st Marines, which had been in reserve behind and slightly to the right of the point of attack, cleared the left bank before the enemy had time to consolidate his gains.50

The main force of the Ichiki unit remained on the point without giving any direct support to the attack while it was being delivered. Immediately it became evident that the assault had failed, however, the enemy began delivering fire from his mortars and 70mm infantry cannon, in an attempt to reduce the Marine position.51 The Japanese then initiated a frontal assault on the perimeter--a large group, about the size of a company, went out into the sea beyond the breakers and came directly ashore against the left flank of the 2d Battalion. This attack, however, was likewise shattered at the water's edge by heavy fire from machine guns and from 37mm guns loaded with cannister.52

The Japanese artillery and mortar fire from the right bank of the river spoke eloquently of a fairly large force, and, at about 0400, the 75mm batteries of the 3d Battalion,

11th Marines, laid down a concentration in that area. A fire-fight of great intensity and at close range developed, with the Marine forces enjoying the advantage of a partial enfilading of the enemy position by fire from weapons emplaced on the projecting left bank of the river. A second artillery concentration was placed on the enemy force at about 0515.53

In the meanwhile, General Vandegrift decided to execute an enveloping movement, since most of the enemy appeared to be concentrated within a reasonably small area. The 1st Battalion, 1st Marines, (Lieutenant Colonel Lenard B. Cresswell), reverting from division reserve to regimental control, was ordered orally by Cates to go upstream, cross the river, and attack to the northwest along the right bank, thereby taking the enemy on his rear and his left flank.54

The movement was an unqualified success. The battalion crossed the dry upper stream bed of the creek, debouching from the jungle onto a grassy plain 3000 yards inland. At this point it assumed the formation which it was to hold for the rest of the action. Companies A and C, each with one platoon of Company D (Weapons) attached struck out straight for the beach at an azimuth of 15º to allow the force to come in well behind the enemy pocket.

Company B, with the mortar platoon and one machine gun platoon of Company D attached, formed the reserve. Operating under the battalion executive officer, this company moved toward the beach with its right flank resting on the left bank of the Tenaru--or Ilu, as it was then called. As it moved toward the mouth of the river, the company left details of squad size in position along the bank to impede any attempt of the Japanese to withdraw across the river. The rest of Company D, operating as riflemen, also moved north with its left flank on the right bank of Alligator Creek. Headquarters Company moved generally in the rear of the assault companies.

Immediately upon reaching the beach, Companies A and C swung to the left and began moving toward Alligator Creek (the "Tenaru"). Several attempts were made by the enemy to break through the force that was compressing them into an ever decreasing area. A thrust toward the east, along the beach, was stopped by elements of Company C. Another, up the right bank of Alligator Creek (the "Tenaru") ran into Company D and was wiped out.55

An attack by light tanks, advancing across the bar, was moderately successful, one tank being lost to enemy mines and weapons. Marine riflemen thereupon closed with the survivors of the enemy force and exterminated them. The action concluded at 1700, after 16 hours of constant fighting.

The Japanese suffered almost total casualties in a group that numbered about 900 men. A few stragglers managed to escape into the hills to the south, and 15 enemy were taken prisoner. The cost to the Marines was 34 killed and 75 wounded.56

While Pollock's battalion was holding its positions at the mouth of the river and Cresswell was getting into position on the enemy's left flank and rear, four pilots of VMF-223, led by Major Smith, made their first interception. At 1207 they engaged a flight of six enemy fighters near Savo Island, and the leader scored the first of his many

56. The 2d Battalion, 1st Marines which bore the brunt of assault, suffered most heavily, losing 25 killed and 44 wounded. Seven were killed and 13 wounded in the 1st Battalion of the same regiment, while the Special Weapons Battalion, a Division unit, lost two killed and 14 wounded.

kills. This was the only enemy plane shot down in the engagement, which cost the Marines one plane when Technical Sergeant Johnnie D. Lindley crash-landed upon return to the airstrip.57

While the preliminary gambits which led up to the Battle of the Tenaru were being performed, the Japanese likewise deployed forces for a second attempt to build up their strength on Guadalcanal. On 19 August, the day upon which Ichiki's reconnaissance patrol was wiped out, the rear echelon of his force departed Rabaul en route to Guadalcanal. About 700 of this unit were embarked in four old destroyer transports (Patrol Boats #1, #2, #34, and #35), together with 800 "marines" of the 5th Yokosuka Special Landing Force on the converted cruiser Kinryu Maru, screened by light cruiser Jintsu and three destroyers.

This force, in itself unable to cope with anything in the nature of an air attack, was covered by two task forces, each built around carriers, that operated generally to the eastward of the transports. Closer in there was the seaplane carrier Chitose, fitted with four catapults and carrying 22 float planes.58

To counter this attempt, two United States task forces were operating in an area generally


57. The psychological effect of the arrival of friendly planes is indicated in the following anecdote contributed by LtCol Joseph N. Renner. When he arrived on 30 August, he was told by a Marine of the 1st Division that the planes had done a wonderful job. The Marine was loud in his praise of "that guy Smith" who, he assured Renner with the utmost sincerity, had shot down at least fifty planes--he hadn't heard anything within the past few days, and the score perhaps was larger.

southeast of the lower Solomons and conducting searches to the northwest. Each of these forces likewise formed around a carrier, Enterprise forming the nucleus of one and Saratoga that of the other.

Contact with the enemy was made first on the morning of 23 August, two days after Ichiki and his battalion had been annihilated. The contact, made by long distance reconnaissance plane, was not developed. Marine planes from Henderson Field, attempting to follow it up, were not successful because of a heavy overcast, and returned to the field. They were followed by 35 Navy planes from Saratoga--29 dive bombers and six torpedo planes--which landed just at nightfall, at 1700.59 The night was marked by a shelling of the perimeter by the enemy destroyer Kagero, one of the ships which had brought the Ichiki unit to the island.60

Next day--24 August--the enemy task force was located and attacked. Ryujo was hit repeatedly and finally went out of control and burned. Chitose, also hit, was able to make her way, badly damaged, to Rabaul.61 While the ships were under attack, Henderson Field was struck by 16 single engine carrier type bombers, escorted by 12 Zeros. The enemy planes were attacked in turn, at 1420 by F4F-4s of MAG-23, which shot down 10 bombers and six Zeros at a loss to themselves of three pilots missing and one wounded. Minor damage only was done to the airstrip.62

On the night of 24 August, the persistent Kagero returned again to shell the perimeter, accompanied by four sister destroyers--Musuki, Yayoi, Isokaze, and Kawakaze. Once again there was only minor damage to the perimeter.63

The Enterprise, meanwhile had also been struck and damaged by enemy air attacks to such extent that she had to withdraw from the action. This ship casualty resulted in an accretion of strength by the Guadalcanal Air Force. Flight 300, airborne when the carrier retired, took refuge at 1845 on Henderson Field. It consisted of 11 SBD-3s (6 from VS-5, 5 from VB-6) under command of Lieutenant Turner Caldwell, USN.64

Enemy transports, whose movement toward Guadalcanal had precipitated the action, continued on their assigned mission. They were attacked by 12 SBDs from the Guadalcanal airstrip, and the cruiser Jintsu was hit, damaged, and forced to withdraw to

Truk for repairs. The auxiliary cruiser Kinryu Maru was hit, set afire, and abandoned, and a destroyer, the Mutsuki, was sunk by B-17s of the 11th Bombardment group, based on Espiritu Santo, while standing by her.65

The untoward results of the attempted reinforcement were such as to force the Japanese to abandon the effort. Surviving units of the enemy transport force withdrew to the Shortland Islands.

Some time immediately after the defeat of the Ichiki unit, the Japanese forces to the east of the perimeter committed the only atrocity against European civilians on Guadalcanal of which we have record. At an undetermined date late in August two priests, Father Arthur C. Duhamel, of whom we heave heard above, and Father Henry Oude-Engberink were tortured and killed, as were Sister Sylvia, a French nun, and Sister Odilia, of Italy. The murders were witnessed by a third nun, Sister Edmée, also of France.

These people, all missionaries of the Society of Mary, had been on the island at the time of the Japanese invasion. They were stationed at the mission at Ruavatu, between the perimeter and Aola. Other members of the order were Father Michael McMahon at Visale, a mission near Cape Esperance and Father Emery De Klerk, a Dutch priest at Tangarare, on the south coast directly across the island from Kokumbona, All of them had refused to leave their posts at the time the European colony at Tulagi was evacuated.

Prior to the coming of the Marines, they were not molested by the Japanese. After the American landings, however, the people at Visale were forced to go to Tangarare and then to the mountains. Duhamel and Oude-Engberink, however, remained at Ruavatu because of its remoteness from the scene of action. They were taken at that place by survivors of the Ichiki force led by Ishimoto,66 the local spy, and were ordered to go through the American lines with tales of an overpowering Japanese force, in order to persuade the Marines to surrender or withdraw from the island.

When the two priests and the nuns refused to obey, on the grounds that they took no part in anything but religious matters, they were subjected to a week of torture and starvation. Since they remained obdurate, they were bayonetted. The bodies were buried in a native hut, whence they were recovered and buried by Father Frederic P. Gehring, at the time on duty with CUB-1.67

Chapter V: The Battle of the Ridge

The coming of the first air units had an effect which would be difficult to reconcile with the size or the power of those units.1

On 22 August, while Smith's fighters were providing air cover for the Alhena, newly arrived from Espiritu Santo with supplies and a part of the 2d Marines, the local air force, as we have seen, was augmented by the arrival of part of the 67th Fighter Squadron of the Army Air Force. On that day, five P-400s led by Captain Dale D. Brannan, arrived at the field after a series of long over water jumps from their training area near Noumea. 2 They were followed five days later by nine more.

2. WD, MAG-23, p. 2, and History of the 67th Fighter Squadron. These planes, designed for export to the European theater, had certain mechanical limitations (given in great detail in the history of the squadron) which made them unsuitable for high-level interception or combat. Their oxygen equipment, for example, called for high pressure bottles, unobtainable in the area. This meant that an absolute maximum altitude of 14,000 feet was imposed upon the willing and highly skilled pilots. Since the enemy bombers customarily used the 25,000 to 30,000 foot levels, the P-400s were useless as interceptors save on rare occasions, and they were therefore ordered t perform low level reconnaissance. From this limitation likewise arose the curious fact that they became outstanding ground support planes, functioning thus in a field of endeavor which had previously been considered almost exclusively one for Marine air.

On 30 August, in the midst of an enemy raid which sank the destroyer Colhoun, two more squadrons of MAG-23 arrived, led by Lieutenant Colonel William J. Wallace, commanding officer of the group. When these 31 planes came in--19 F4F-4s of VMF-224 and 12 SBD-3s of VMSB-231--Wallace found that only four fighters of the first echelon remained operable. The rest had fallen victim to operational mishaps, enemy air raids, and combat damage.3 There was, therefore, a preponderance of pilots in all save the most recently arrived units--Brannan's 67th Fighter Squadron, for example, had only three planes left in operating condition of the total of 14 which had arrived at the island.4

By the end of the month the Cactus Air Force, as the mixed Marine, Navy, Army Air Force Group had begun to be called, had grown to the following strength:

VMF-223 (Major John Smith) 10 planes
VMF-224 (Major Robert E. Galer) 19 planes
VMSB-231 (Major Leo R. Smith) 10 planes
VMSB-232 (Lieutenant Colonel Richard C. Mangrum) 12 planes
Flight 300 (Lieutenant T.F. Caldwell) 10 planes
67th Fighter Squadron (Captain Dale D. Brannan) 3 planes

During the ten days which had elapsed since the arrival of the first planes, a schedule of routine daily flights had been evolved. Four planes fighter patrols left the airstrip at 0545 and 1400 daily, returning at 0830 and 1830 respectively. Occasionally a mixed fighter-dive bomber squadron operated at night to the northwest in search of enemy shipping. So far, such flights had been without effect.5

5. WD, MAG-23, 31 August 1942.


MAJ JOHN L. SMITH, first Marine ace of World War II, received the Medal of Honor for his feats as a Guadalcanal fighter pilot.

The matter of interception of enemy bombers, however, found the local air force more effective. A total of 56 enemy planes had been shot down during the ten days, as against a loss of 11 for the mixed Cactus Air Force. Concurrently with this combat, local planes had begun to fill another useful role--that of giving air cover and protection to the supply ships that were beginning to appear from the southeast. The Alhena, for instance, was protected during her approach and unloading on 30 August, when she brought in the forward echelon and the supplies of MAG-23.6

With the arrival of aircraft, the ground forces at Guadalcanal found themselves in a much improved position as regarded intelligence. While there was still far too little direct and accurate enemy information, it was now possible at least to get some idea of where and how he was landing. Aerial observation, to seaward at least, with its tremendous widening of the area capable of being scouted, brought invaluable, although frequently disquieting, information to General Vandegrift. It was learned, for instance, that landings of Japanese reinforcements were taking place both east and west of the perimeter. It was learned also that many of these landings were taking place at night.7 Marine Corps, Navy, and Army planes, few in number though they were, attacked at sight any Japanese shipping within range and inflicted damage that even the single-minded enemy was not prepared to suffer needlessly.

Three days after the defeat of the Ichiki detachment, for instance, patrol planes from the field participated in the Battle of the Eastern Solomons by attacking an enemy force of transports, cruisers and destroyers 150 miles northwest of the island, inflicting damage.8 Something over a week later, on

2 September, and second and larger force was attacked during the night while unloading supplies and troops well to the east of the perimeter, near where the Ichiki unit had landed.

Such was the information and the support obtained from the newly arrived air units. It became apparent that the enemy had not given over his plans for a counterattack, and it became evident that he was so disposing major forces as to be able to launch separate or coordinated attacks from either the east or the west.

The Ichiki unit was the first large enemy group to land successfully after the 1st Division assault; at least two previous attempts to land reinforcements had been made, however. On 8 August, at 2200, Seiyo Maru, with 414 men of the Sasebo 5th Special Naval Landing Force embarked, departed Rabaul for Guadalcanal. It was sunk with all hands while rounding Cape St. George. On 16 August a small detachment of the Yokosuka 5th Special Naval Landing Force was put ashore near Tassafaronga. Working its way eastward, this detachment found approximately 2000 men of the original garrison gathered near the line of the Matanikau River, where they had prepared positions.9 Late in the month, however, enemy forces began landing at night to the east and the west. On 29 August, four destroyers -

Fubuki, Shirayuki, Kawakaze, and Umikaze - landed 900 men at Tassafaronga. Next might, the destroyer Yudachi landed the rest of the Ichiki unit at the same beach, while on 31 August, all the above craft, plus the destroyers Amagiri, Kagero, and Suzukaze, landed 1200 men of the Kawaguchi Brigade at Tasimboko, well to the east of the Tenaru River.10

Other landings took place in a similar manner, and by 6 September, the enemy strength on the island was distributed as follows:11 East of the perimeter, 2990 men were between Taivu Point and Tasimboko, including Headquarters, 35th Infantry Brigade; main strength of the 124th Infantry; and the second echelon of the Ichiki detachment, with a few survivors of the first echelon. West of the perimeter, beyond Kokumbona, there were about 200 men, consisting of parts of the 124th Infantry (being assembled by Colonel Oka), some Special Naval Landing Force personnel, and the 11th and 13th Pioneers.

To the eastward of the perimeter there must have been almost a continuous nightly ship-to-shore movement. The Kawaguchi detachment--so called from the name of its commanding officer, Major General Kiyotake Kawaguchi, commanding the 35th Infantry Brigade--landed during that period as we have seen. Immediately after landing, engineering personnel attached to the unit began the monumental task of cutting a direct route across the rolling jungle country and into the foothills, across the unnumerable hills and ravines and streams that lay between them and a bivouac area in the terrain south of the airfield, whence an attack against their objective could be launched from the terrain which dominated it.12

Parts of this information came from planes which patrolled the area constantly. Other parts came from the reports of patrols engaged in hunting down the scattered remnants of the Ichiki detachment and from messages brought in by natives whose gardens were being pillaged by the enemy.

The Marine forces, however, did not realize the size of the newly arrived enemy units, nor did they have any definite knowledge of their movements. It was only known that there was an increasing amount of activity and that it was becoming more and more difficult for patrols to penetrate the areas lying east of the perimeter.13

The information of the gathering of forces near Taivu, sketchy and incomplete though it was, was more detailed than that which existed about the enemy to the westward. One action had been fought against the units between Kokumbona and Matanikau, but, although heavy casualties had been inflicted upon those forces, the main body had made its way into the hills back of the beaches.

Second Action Along the Matanikau

A second action was planned against the same area, consisting of a shore-to-shore movement on 27 August by the 1st Battalion, 5th Marines (Lieutenant Colonel William E. Maxwell), supported by the overland thrust of an additional company. Diversionary fire by the 11th Marines was to be directed to the area of the mouth of the Matanikau, to create the impression that an attack across the river was impending.14

Plans for the operation cannot be reconstructed at this time with any assurance of accuracy. Orders were given orally by the regimental to the battalion commander. The latter did not disclose them to his staff in toto, and there is a complete disagreement as to just what constituted the battalion's mission.15

15. Letter, Major Milton V. O'Connel to Commandant, Marine Corps, 8 February 1949. It seems clear that Maxwell was directed to land, make his way eastward to the mouth of the Matanikau, reembark his battalion there, and be back in his defensive position on the perimeter by nightfall. Interview, Captain E.J. Snell (at that time assistance regimental adjutant, 5th Marines), 19 May 1949. Snell was present at the conversation between Hunt and Maxwell.


The battalion landed without incident at a spot recently vacated by a force of enemy, a fact made evident by the presence of hot food. The landing was completed by 0730, and movement to the east was begun at once.

The nature of the terrain, and the complete uncertainty regarding enemy strength and location, dictated the tactics which, in fact, made it impossible for the battalion commander to carry out the mission he understood had been given him. The narrow beach, bordered by thick scrub, shelved off into a narrow band of flat coastal land. This level stretch, from 200 to 300 yards wide, thickly overgrown, was threaded by a narrow road, the western extension of the coastal road that ran through the perimeter. On the inland side, the flat land terminated in a line of low coral cliffs, which in turn were the seaward faces of a jumbled ridge system that paralleled the beach. The ridges were cut at frequent intervals by deep, jungle-choked ravines which opened to the flat land. Passage along the ridges, therefore, would entail a series of cross-corridor movements, made the more difficult by the necessity of cutting through dense jungle in each corridor and by the additional fact that on the ridges themselves there was a combination of tough, five foot high kunae grass and murderously hot sun.16

Security dictated that a force move along the ridges to prevent a flanking attack, should it happen that enemy forces were in position there. Company C was given the mission and moved off to get into position. Company B moved off at the head of the column along the trail, followed by Headquarters Company and part of Company D. Company A furnished rear guard security.

Within an hour it became apparent that Company C could not keep pace with the main body. An additional bad feature was that, in the absence of "walkie-talkie" (TBY) radios, all contact between the two groups had to be by physical contact. By 0900 contact had been lost, and the battalion halted. Company C was ordered to come down off the high ground and take place in the column behind Company B. The 1st Platoon, Company B, reinforced by one machine gun platoon from Company D was ordered at the same time to move up onto the ridge to its right and continue with the mission previously held by Company C.

Forward movement was resumed at about 1030. Within a half hour, at a point where the coral formation of the ridges squeezed the coastal strip into a narrow corridor less than 200 yards wide and where the thickly growing jungle scrub thinned out into a coconut grove, a deep ravine opened to the flat land. The Japanese, well dug in and taking advantage of the restricted avenue of approach and the splendid defensive possibilities offered by the coral, opened fire upon the advancing elements of Company B. This fire, initially from machine guns emplaced at the base of the cliffs and in the scrub at the edge of the beach, was immediately augmented by mortar fire, and Company B, deploying to each side of the trail, began to suffer casualties.

A firing line was built up, and mortars from Company D, going into position along the beach, began laying down fire upon the base of the cliffs. Company C, now in position behind Company B, was ordered to attempt a flanking movement around the left (seaward) flank. It was expected that the Company B platoon operating along the ridge would envelope the enemy's left flank.

The Company C maneuver failed, the company finding it impossible to progress beyond the line still held by Company B. The expected movement on the part of the right flank elements did not materialize for two reasons.

First, the problem of contact and communication had not been solved. Second, the combination of fantastically difficult terrain, jungle, grass, and sun, had begun to inflict damage upon that platoon that was more serious than that inflicted by the enemy. Messengers sent by the platoon appear to have been overcome by heat on the way in and taken to the battalion aid station. The leader

of the machine gun platoon was overcome and carried to the same place. The only message received by the platoon, on the other hand, was to "stand fast."17 It was the more easily obeyed because the platoon leader had no assurance that the mortar fire from Company D, falling along the base of the ridge below him, would be lifted when he began to advance.

In the meanwhile, Maxwell realized that he could not carry out his instructions to the letter. The enemy emplacements holding up his progress sheltered a force of unknown size, but of sufficient strength to deny him passage along the coastal strip. The terrain further inland had proved itself to be an enemy almost as effective in restricting his movement as the Japanese themselves. Convinced that the most important phase of his mission was that of returning prior to dusk to resume his defensive position on the perimeter, he requested that boats be sent to a point near Kokumbona so that he could withdraw. In anticipation of their arrival, he began moving a portion of the battalion to the expected point of embarkation.18

Two hours passed before the expected answer came. In the interval between the messages, part of Company B was withdrawn to the beach and, with the wounded, was embarked and sent on its way to Kukum. The answer to Maxwell's message came. Maxwell was told that he was relieved of command, which should pass to his next senior (O'Connell), that the battalion would remain in the field, and that the enemy force would continue to be attacked until defeated.19

O'Connell assumed command at once, and shortly afterward Colonel Hunt himself arrived at the beach and remained with the battalion as it went into position on the ridge for the night.

The attack, pressed home early next morning, met with no opposition. The entire enemy force had withdrawn during the night up the ravine which led back into the hills and around the mouth of which the Japanese had made their stand of the day before.20 The battalion moved by the coastal road to Matanikau village, embarked, and returned to the perimeter.

The Tasimboko Raid

The Tulagi area, after the first two days of the operation, had been relatively quiet. After the bitter fighting which attended the assault on and reduction of the island group, no contact had been made with enemy forces, save in patrol actions. Occasional visits by enemy destroyers and submarines occurred however, and when American ships began using the excellent harbor, enemy aircraft dropped bombs in the area sporadically, generally while en route to the more lucrative target of Henderson Field.21

Little damage was suffered by the Marines in any of these raids, the largest single loss being that of a YP boat, set on fire when the area was bombarded by three enemy destroyers shortly after midnight on 8 September.22

The defenses of the island, initially oriented against an expected attack from Florida Island, were strengthened by the arrival of the 5-inch Navy type guns of the 3d Defense Battalion. One battery of these guns,

using wooden advanced-base platforms, was brought ashore from the Betelgeuse on 1 September. It was necessary to float the platforms in, while the guns themselves were manhandled, by block and fall, up the face of the coral hill where they were emplaced on the southern tip of the island.23

The importance of the area in the matter of ground force activity lay in the fact that from it were mounted some of the more important patrol actions of the campaign. Florida Island was combed for remnants of the defeated Tulagi garrison as well as for signs of newly arrived enemy forces. With the assistance of loyal natives., Marine patrols ran down and captured or wiped out numerous survivors of the 7 August assault. The most diligent search, however, failed to indicate that there had been any attempt at reinforcement.

By the end of August, a combination of lack of employment for the relatively large force on the island, and a growing need for more troops on Guadalcanal, had led to me transfer of a part of Rupertus' forces. On 21 August, Combat Team 2 (2d Battalion, 5th Marines) passed across the strait on board the destroyer transports of TransDiv 12, newly arrived with badly needed supplies of food. On 31 August, the Raider Battalion had likewise been moved across to the perimeter, and on the same day, orders were received by Rupertus to move the Parachute Battalion across.24

The Raider Battalion, to which the Parachute Battalion had now been attached for operational purposes, went into bivouac initially west of the Lunga and immediately behind Kukum. On September 2, two companies of the Raiders patrolled Savo Island, with negative results. Plans to execute a landing near Tassafaronga25 the next day were abandoned because of a curiously fortuitous error26 and the two battalions moved into a gap on the south flank of the perimeter. Work was begun on the construction of defensive positions.

We have seen above that, while the pressure of enemy forces to the east was realized, information regarding their size was sketchy and nothing was known of their composition. Clemens and his native scouts brought details that let to the conclusion that perhaps 300 enemy, well armed and occupying well constructed defensive positions, were in position immediately west of the village of Tasimboko. It was decided to wipe out this nucleus, and Edson was given the task.

Plans for the operation were more elaborate than those for the unfortunate Kokumbona affair which preceded it. The unit was to move in two echelons, using two APDs for the task. The Raider Battalion, in assault, would land immediately before dawn to the east of the village and strike out to the west. Gunfire support was to be given by the two destroyer transports, so timed that the assault force would benefit by the element of surprise. Air strikes likewise were planned, and Edson would be able to count on the support of the planes of MAG-23. An initial strike would be repeated, against designated targets, on request from Edson. The operations would be completed in one day, 8 September.

Immediately before the battalion embarked for the assault, disturbing news came in from native scouts who had been operating

25. During these moves by the Japanese to reinforce and build up their forces on the island, Commander, Task Force 62 wrote to Admiral Ghormley on 29 August as follows: ". . . No additional raiding groups were available for mopping up outlying Japanese detachments, although the plan had required operations of this nature on both August 7th and 8th. Outlying detachments in the vicinity of CACTUS (Guadalcanal) and RINGBOLT (Tulagi) positions exist; it is planned to mop these up within the next few days using the First Raider Battalion."
26. Two APDs -- the Little and Gregory -- were used in the movement. When they returned after dark to Lunga, Colonel Edson decided to keep the men embarked to facilitate the next day's operation. By the time word was got to the ships, however, a part of the men had already disembarked, and he decided to bring the whole group ashore. The two ships were sunk later the same night. Interview, Stiff, Sweeney, and Sperling, 4 February 1949.


in the vicinity of the target. Clemens, who translated their reports, gave it as his opinion that there had been a sudden increase in the size of the enemy garrison. Edson, according to Clemens, might well find himself assaulting positions occupied by several thousand well equipped men. Little credence was placed in the mathematical accomplishments of Clemens' followers, however, and it was decided to carry the planned action through, even though, there may have been a slight increase in enemy strength.27

At 1800 on 7 September, the 1st Raider Battalion embarked at Kukum on the Manley and McKean and two small craft--YP boats, converted tuna fishing launches from the California coast. The 1st Parachute Battalion was moved down to Lunga Pint to bivouac for the night, having been warned to stand by for movement at any time subsequent to 0600 on 8 September.

The movement was carried out according to plan and on schedule. The landing area was reached prior to 0500, and landing craft made the first of two trips to the beach during total darkness, at about 0520. They returned immediately for the remaining troops.28

The ship-to-shore movement was conducted with every precaution to assure surprise. Landing craft traveled at reduced speed to cut down exhaust noise. Considerable worry was caused when there was an accidental discharge of a rifle as the boats of the first wave were approaching the beach, but as far as could be determined, the enemy was not alerted.29

Movement began at daylight, with Company B on the beach, Company A in contact on the left, and Company C striking further inland, to attack from the south in an enveloping movement. At 0635, planes of MAG-23 left the airstrip to deliver their first strike against the enemy positions--2 SBDs, for bombing accompanied by four P-400s, whose mission was strafing.30 They struck at the area west of the village as Edson was moving toward it. At about the same time, Manley and McKean began lobbing shells into the same target.

Concurrently with the air strike and the naval gunfire, two United States ships - Fuller and Bellatrix - under destroyer escort, came into sight from the southeast, on their way to Lunga. This event had a significance that became apparent only later, as will be discussed below.

By 0855 Edson reported to the perimeter that he had made contact, and that two pieces of enemy artillery had been overrun.31 The contact had been light and there was still no information as to the strength of the enemy, who appeared to have withdrawn toward the village.32 Edson requested that bombers be kept in the air, and, in answer to this request, General Vandegrift advised him that ten planes would be in continuous support, with another squadron on call.33

At 1045 the Raiders reported still further progress, but included in the message was a request for advice on the possibility of landing more troops to the west of Tasimboko. Division replied that such a move was not feasible and suggested that the Raiders reembark and return to the perimeter. Forty-five minutes later a message from Edson announced that more artillery pieces had been taken and that the battalion was advancing slowly against heavy opposition. The enemy was now estimated to number about 1000 well armed and well equipped troops. Pressure upon the attackers was increasing; the enemy was using field artillery at point-blank range.34


27. Interview, Colonel Edmund J. Buckley, July 1947. There had been a tenuous bit of confirmatory evidence. On the night of 5 September, another officer of the Raider Battalion had come to Buckley, saying that he thought ships must be passing to the eastward. He had noticed a series of regularly spaced waves coming ashore, that seemed to be those of a ship's wake.

About this time, contact was reestablished between the various companies of the battalion, after having been lost for an hour or more, and, at about the same time, the 1st Parachute Battalion, which had embarked and left Kukum at 0818, reported to the Raiders' headquarters35 together with Company E, 1st Raider Battalion. In view of this, Colonel Edson decided to go through with the attack, requesting additional air support.36 This was given him in the form of a strafing attack on enemy positions by four P-400s.37 An enveloping movement was developed from the south, with the 1st Parachute Battalion providing flank and rear guard security for the Raiders' main body.

When the attack was finally pressed home and the village was entered, it was found that once again, the main body of the enemy had escaped destruction.38

Here also it was discovered that the reports turned in by the native scouts and discounted by the division staff had been far more accurate than had been believed. On the basis of amounts of food, equipment, ammunition, and other material, it was estimated that no less than 4000 Japanese had been in the vicinity until shortly before the attack.39

Documentary material was taken for intelligence purposes. Among the captured arms were found several 47mm antitank guns of a type that "plagued us later on," to quote the words of Colonel Griffith in his letter quoted herewith in a footnote. Fuses were removed from shells and cast into the sea, and the same treatment was given breech mechanisms. Other material was either burned or rendered useless, as in the case of food, by unorthodox but effective means.

There was much speculation as to the reasons why a large force, of the kind that had obviously been present only shortly before Edson's landing, should have allowed itself to be driven off by a comparative handful of men. (The total strength of the attacking force did not exceed 850, and probably was considerably less.) It was suggested that the fortuitous appearance of the Fuller and Bellatrix, with their escort of destroyers, created the impression that a large landing was under way. The coincidence of gunfire support and the air strike with their appearance may well have [helped] the Japanese to come to such a conclusion, although it is now known that the main body of the Kawaguchi Brigade had left the area on the first stages of its movement toward the perimeter.40

Save that the enemy force was not destroyed, the action was an unqualified success. The cost in casualties was extremely low--two killed and six wounded--while the enemy had lost at least 27 dead. The entire base was reduced to rubble, and neither food nor equipment remained in a usable condition. Those forces which later were observed making their way inland were presumably in a precarious situation in the matter of supplies. With this aspect of the matter in mind, it is possible to say that the Tasimboko raid had a profound effect upon the Battle of the Ridge, where Edson finally met in battle the enemy general whom he missed at Tasimboko.

Gathering Strength

While the above mentioned patrol actions were being fought to the east and the west, and while the Marines were learning the strength and location and tactical peculiarities of the enemy, other activities important to the operation were being speeded up. The flow of supplies, interrupted almost as soon as it began when Fletcher found it advisable to withdraw, was renewed as Turner pushed his ships into the area at every opportunity. The remaining regiment of Vandegrift's division -

the 7th Marines (reinforced)-- was on its way from Samoa. Malaria, which was to be a scourge from October onward, had not yet made its appearance in significant strength.

The most welcome accretion of strength, as we have seen, was that afforded by the coming of the various squadrons of MAG-23. The improvement of the situation had been almost instantaneous, and the reinforcements for the initial group, arriving late in August, had resulted in a growing feeling of confidence on the part of the air as well as the ground personnel.

September 3 saw the arrival of the command echelon of the 1st Marine Air Wing, when Brigadier General Roy S. Geiger, accompanied by Chief of Staff, Colonel Louis E. Woods, and his intelligence officer, Lieutenant Colonel John C. Munn, arrived at Henderson Field by transport plane.41

MAJGEN ROY S. GEIGER, veteran Marine aviation commander, established 1st Marine Air Wing Headquarters on Guadalcanal on 3 September. His mixed, all-Service command soon became known as "Cactus Air Force", because of the code-name for the island.

Geiger immediately reported to Vandegrift for duty and set up his headquarters, using the staff of MAG-23 as Wing staff. The command post was established close to division, and liaison in the form of daily conferences between Vandegrift and Geiger became normal procedure. Colonel Kenneth H. Weir, Marine Corps aviator, operated at Vandegrift's command post as permanent contact man, and liaison at the level of MAG-23 was constant, with Colonel Gerald Thomas and Lieutenant Colonel Merrill B. Twining keeping in touch continually with the air arm of the team.42

Improvisation was necessary in almost all administrative as well as in technical matters. To keep up with the matter of personnel and other administrative records, the Wing functioned with a staff consisting of one sergeant and an enlisted clerk. Lieutenant Robb, Naval Aviation, held a permanent berth at Wing Headquarters where his duties consisted in keeping track of the Naval aviators who came more and more often to the field from carriers in the vicinity.

Lack of adequate equipment for fueling and arming planes likewise made it necessary for the aviators to employ makeshift methods, sometimes of rather primitive character. Bombs, even as late as the Battle of Guadalcanal in November, had to be slung in by man power. Radio communication with planes on patrol gave rise to another problem--


41. Geiger, during the course of the war, acquired something of a monolithic stature. Aside from the personal qualities which made his staffs function almost automatically, he never forgot that there was a ground war being fought. His visits to the front lines--never very far from his Command Post on the most exposed hill in the badly battered perimeter--have become legendary. His study of ground problems was intense and perhaps teleologic--he became the first Marine officer to command an army. Upon the death of General Simon Bolivar Buckner on Okinawa, Geiger succeeded to command of the Tenth Army and held it until replaced by General Stilwell.
42. Conference, Major General William J. Wallace and Brigadier General William O. Brice, 4 January 1949. Weir was the first Marine Corps aviator to land on Guadalcanal. He came ashore with Vandegrift on 7 August.


the channels used by Army planes differed from those used by Navy, and the Army planes could not receive Navy traffic. This matter was resolved by using the radio from a grounded P-400--twin microphones were rigged so that messages could be sent simultaneously to all planes.43

The Battle of the Ridge

Immediately after the raid on Tasimboko, signs began to appear that the movement by the enemy from that base was something other than the precipitate flight it had been thought to be.

Patrols from the 2d Battalion, 1st Marines, operating in the area lying east and southeast of the perimeter encountered opposition with increasing frequency. Mountain guns, singly and in batteries, were found at various points within range of the perimeter. These weapons, always in perfect condition and carefully smeared with cosmoline, frequently were found unguarded. On several occasions a single enemy soldier was found, evidently merely a caretaker left to service the weapon and the ammunition that invariably was found buried nearby.44

From native scouts also came news of the movement of large bodies of troops, groups that were in no way similar to the small bands of disorganized, ill-equipped survivors of the ill-fated Ichiki detachment. There was an air of purpose and direction about them that was apparent even to the local natives who had deserted their villages and fled toward the perimeter.

By 10 September it was known that the enemy was less than five miles east of the perimeter and that he was cutting a road to the south.45 Here again it was from friendly natives that the most authentic and dependable intelligence data came, for the enemy movement was by this time taking place under the cover of rain forest trees, safely hidden from aerial observation.

These considerations pointed to the strong possibility that an attack would be made upon the perimeter from the south or the southeast. The fact that supplies of all kinds were landed indicated that the enemy force, subsequently identified as the Kawaguchi Brigade, intended operating from the eastward. The additional fact that much of its supplies had been destroyed by the Raiders made it extremely likely that there would be little delay in the launching of the attack, for even the numerous native gardens in the region were not sufficient to enable a force of that size to live off the country.

The situation brought up again, and imperatively, the problem of defending the inland sector of the perimeter.

The alternative to a complete and continuous defensive line was to establish a series of strong positions wherever the terrain permitted. Some of these positions were manned by personnel of the rifle regiments and battalions; others were manned by special troops of one or another unit. The 1st Amphibian Tractor Battalion, for example, was given the responsibility of maintaining a defensive position located on a ridge which commanded the approach from the west, on the inland extension of the left flank, The Engineer Battalion tied in with the right flank of 1st Marines positions, and extended that flank to the left elements of the Parachute Battalion. The Pioneers went into position on a small hill immediately east of the Lunga River, to the southeast of the Amphibian Tractor Battalion detachment.

On 9 September, General Vandegrift's command post, previously situated against a small ridge on the northwest of the main airstrip, was moved to the inland (south) side of a small hill just inside the jungle south of the field. This was done because the former location was well within the target area of the enemy air strikes, which, after the first day, had been directed solely against the airfield.47

On the same day the Raider Battalion, still with the Parachute Battalion attached, returned to the positions they had occupied prior to their foray against Tasimboko - astride a ridge immediately inland from the airstrip.

Just south of the airfield, the land begins to fold into the jumbled terrain of the foothills, and the open country ends in jungle-covered flats and ravines. Now and then a small area of kunae grass appears, generally on top [of] a low hill or ridge.

One such ridge, perhaps a thousand yards long and with its length running northwest and southeast, rose out of the jungle a short mile from the runway. It dominated the field, with which it was connected by a narrow road. The ground surrounding the ridge was lower, falling away toward the stream bed of the Lunga, lying to the west and the southwest, and toward that of the Tenaru, toward the east. In each case the land was covered with unbroken jungle.

Deep ravines, heavily and in some cases impenetrably wooded, bordered the hill on all sides. Four short but distinct spurs jutted from it, two on each side, slanting away from the ridge line, and between the knob at the southern extremity and the northernmost end of the ridge rose two other hillocks. Just west of the southern end of the ridge in a heavily overgrown flat, there was a deep impassable lagoon.

By 12 September, it became obvious that action was impending. A reconnaissance by Edson, his executive officer (Griffith), and two enlisted runners convinced the battalion commander that there was an enemy force of considerable size to his front. He decided to patrol the area next day with his entire battalion, to throw the enemy off balance, and then return to prepared positions.

During the afternoon, as if to give point to his realization, an air raid struck, and a stick of bombs was dropped along the long axis of the ridge - a clear indication that the enemy was aware of the presence of a strong defending force there.48 Edson called for a conference of his company commanders, to be held during the evening, at which time plans for the next day's movements would be discussed.

LUCKIER AT HOME THAN AT EDSON'S RIDGE, MajGen Kawaguchi and friends pose here in a moment of relaxation on an earlier and happier day.

The small size of the force, and the length and character of the sector which it was called upon to defend precluded the possibility of establishing a continuous line. To the left, tying in with the Engineers, were two understrength companies of the Parachute Battalion, whose position in turn extended to the midpoint of the southern slope of the ridge. On their right, Company B, Raider Battalion, held the sector extending toward the right, where it tied in with the left elements of Company C. All its line lay within the grassy area that covered the forward slope save the extreme right flank platoon, which was in position within the jungle. Double apron wire protected the front over the grassy land, while within the jungle


48. Interview, Stiff, Sweeney, and Sperling, 4 February 1949. As the ridge lay perhaps a mile from the airstrip (against which all previous attacks had been launched) and since the axes of the ridge and the strip lay at almost right angles to each other, this bombing was not considered to be wholly fortuitous.


there was single strand wire, looped from tree to tree. Fields of fire had been cut here.

Immediately to the right of Company B, a single platoon of Company C was in position on the edge of the lagoon. Beyond this impassable jungle barrier, the rest of Company C, also behind single strand wire and disposed as a series of small strong points with fields of fire cut for mutual support, extended to the right bank of the Lunga.

At about 2100,49 as the company commanders were leaving the command post at the conclusion of the conference, an enemy plane dropped a flare over the airfield. At 2130, an intense bombardment of the area was begun to four enemy ships lying off the mouth of the Lunga - a light cruiser and three destroyers.50 The shells fell generally in the eastern sector of the perimeter rather than on Edson's positions, although a few of them found targets there. The bombardment lasted for 20 minutes. Just prior to 2130 a flare rose from the area forward of Company B's lines.

Kawaguchi, by this time, had moved northward from his hastily established bivouac area on the right bank of the upper Lunga (found later by the 1st Battalion, 1st Marines and by patrols from the 7th Marines) and had assembled his brigade for the assault.51

As the flare died away, he delivered the first of the headlong, powerful assaults that later were to force the Raiders out of position, back along the ridge, and come dangerously close to splitting the perimeter defenses wide open. Preceded by yelling and scattered rifle fire forward of the juncture of Companies B and C, two strong thrusts were delivered down the east bank of the lagoon. The left flank platoon of Company C was sliced off from its parent company and driven back. The right flank platoon of Company B driven out into the open, and curling back to its right rear, maintained contact on the left with the rest of the company. The result was a partially refused right flank for the company. A third blow, delivered some minutes later, further cut down the strength of Company C by cutting off a second left flank platoon. A small enemy party worked its way down the river and attempted to envelop the dismembered company.52 These attacks were accompanied by a second naval bombardment, which lasted from about 2400 to 0045, falling this time on the airstrip and on the eastern sector lines.

During the rest of the night, Company B was ignored by the enemy and held fast to its exposed position on the southern slope, while Edson attempted to restore his lines. After daylight, companies A and D, as yet unengaged, were sent up the right bank of the Lunga in an attempt to eliminate the enemy salient. The attempt was unsuccessful - the Japanese had dug in and had a strong force in the jungle flats. Also, while Company A was only slightly understrength, Company D had almost ceased to exist save as a skeleton organization, since its men had been used as replacements for the other rifle companies of the battalion.53

Ground activity during the daylight hours of 13 September, consisted, as we have seen, of attempts on the part of the Marines to reestablish their positions and on the part of the Japanese to consolidate and organize the ground they had gained. It became evident, after the failure of the Raiders to eliminate the salient west of the ridge, that Company

B's position was untenable in the face of further attacks. Sweeney, commanding the company, therefore withdrew his men one-third of the way back the ridge and disposed them along a spur that jutted off to the west--rugged terrain that imposed upon him the necessity of using small groups as strong points rather in continuous line. Reinforcements, were given him in the shape of Company B, 1st Engineer Battalion.

In the meantime, air activity had kept pace with the ground action. On 11 September, the day before Edson first established contact with Kawaguchi's force, the 1st Marine Air Wing had received a welcome if temporary, accretion in strength. Late in the afternoon, 24 F4F-4s of VF-5, based on Saratoga, were led into Henderson Field by Lieutenant Commander Leroy C. Simpler. Word had come to ComSoPac of an ominous gathering of enemy naval and ground strength to the northwest, and Ghormley was beginning to look upon the situation on the island with something akin to alarm.54

Caption: WHERE THE TIDE TURNED - Edson's final position on the Ridge.

On 12 September, the perimeter was attacked by 42 enemy planes. Twenty-one of Simpler's fighters joined with 11 Marine planes to fight off the attack, which they did, exacting a toll of 16 planes from the Japanese at a cost of one plane and pilot, lost in a landing mishap.55

Of the four attacks which the enemy air force launched against [the] perimeter on 13 September, only one was pressed home. Two were turned back at 0510 and 1320, one got as far as the perimeter at 1020 before being beaten back, and just at dusk two float planes, in an audacious low altitude strike, shot down an SBD and escaped to seaward.

During the afternoon of 13 September, the commanding officer56 of 2d Battalion, 5th Marines, realizing that his unit (the division reserve) would be called upon to bolster the battered Raider Battalion, conducted a reconnaissance of the area with his company commanders--a wise precaution, for the battalion, as we shall see, was committed piecemeal in total darkness in the midst of Kawaguchi's strongest effort.

The anticipated attack struck at 1830, with a strong movement against the center of Edson's positions, supported by another blow against the right front. Once more the enemy succeeded in opening a gap between Company B and the unit to the right--Company A. Company B's right flank platoon was struck squarely and driven out of position. It fought its way out of trouble and fell back upon Company C, now in battalion reserve.

Kawaguchi's main effort, which came close to succeeding, was directed at the right center of Edson's position. Giving only passing attention to the Raider-Parachute Battalion left flank, which was occupied by an inadequate force of parachutists,57 and neglecting

to follow through on the extreme right flank, the enemy elected to attack along the route which, from point of view of terrain, offered the easiest access to the air field.

After a preliminary blow at 1830 against the juncture of Companies B and A, which drove the right flank platoon of the former back and opened a gap of more than 200 yards between the two units, the Japanese chose to direct their strongest effort at the by now tenuous lines of Company B. At 2130 there was an attack down the ridge itself, which may have been precipitated by the sudden use of a defensive element that up until then had not made its appearance - artillery of the 11th Marines.58

One battery of these weapons, sited for defense of the southern sector, had registered on the area directly in front of Company B earlier in the evening. At 2100, notified by the forward observer, who had established a listening post in Company B's lines, with telephone lines through the Raider Battalion switchboard to that of the 5th Battalion, 11 Marines, that there appeared to be a strong group of enemy in the woods forward of his position, the artillery battalion commander laid down fire in the indicated target area. The range was decreased, with Edson's consent, to such a degree that the next concentration, fired at 2130, fell within 200 yards of Company B's lines.59

The remaining batteries of the battalion were brought into position to fire into the area, and by 2200 another heavy concentration was laid down immediately in front of the Raiders' positions. Once more there was a rush of enemy out of the stricken zone and toward the ridge.

One half hour later, the Parachute Battalion positions were attacked for the first time. An intense fire from mortars, together with confusing shouts and the use of smoke, drove the two companies back to the base of the ridge and then along it to the northward.

Company B was now in a hopeless position. Its right flank, deprived of one platoon and refused, was disposed in a series of small strong points along the western slope of the ridge at the midpoint. The left flank, however, was dangling, and to the left rear, in place of a reserve such as was present to the right rear, there were only the Parachute Companies, disorganized by their retreat.

Edson moved his command post to the top of a high knob that dominates the northern half of the ridge, disposed Company C, the battalion reserve, as a defensive nucleus around the western and southern slopes of the knob, and directed Sweeney to bring his company back and form around it.60 Sweeney's force by this time numbered about 60 men.

The withdrawal was assisted--perhaps even made possible - by the fact that artillery, firing at minimum range and below, placed standing barrages at all points foreword of the company where it seemed possible for the enemy to advance. Then, when the company had completed the movement (in the pitch black of a clear, moonless night)61 the artillery concentration was pulled in still further, and the barrage stood like a wall before the Raiders' positions for the rest of the night. Those enemy who penetrated it were brought under intense fire from rifles and automatic weapons at short


58. The 5th Battalion, 11th Marines, had brought its 105mm howitzers to the island in spite of a prevalent feeling that the jungle terrain would prohibit the use of prime movers. This feeling was responsible for the fact that the 4th Battalion of the same regiment was left behind in New Zealand--its larger and heavier 155mm weapons required specialized equipment for displacing. The 105s, in a pinch could be moved by the ubiquitous amphibian tractor or the almost unbelievably versatile jeep.

range, and those who survived the two ordeals were taken on, hand to hand, by the individual Marines. The myth of the Japanese superman died that night as Kawaguchi's force was cut to pieces.

By 0400, while the attack was still going on, companies of the reserve battalion - 2d Battalion, 5th Marines - began to be committed to bolster up the disorganized left flank. The companies were committed singly, making their way first to a predesignated assembly area between the northern extremity of the ridge and the western end of the airstrip. Company G, arriving first, went into position on the eastern slope of the hill, coming under intense machine gun fire as it moved in and receiving casualties. The other companies, following at intervals, were not aware of the fact that a part of the Raiders' line had been withdrawn since their reconnaissance of the previous day, made their way up to, and in some cases through the lines. Filling the gaps in the Raider Battalion's positions, they helped in standing off the final efforts of Kawaguchi's infantry.62

By daybreak, the attacks had died away, and aside from desultory rifle fire, there was little sign of life in the woods south of the ridge. A few enemy, isolated when their companions withdrew or were wiped out, remained in position on the ridge and in the draws beside it. They were hunted out and killed.

The coup de grace, if one were needed, was given by the P-400s of the 67th Squadron. Leaving the field just after daybreak, they strafed the woods whence the attacks of the previous nights had come, and, according to the remarks of an enemy officer as quoted by Robert Sherrod in his account of the aviation activities of the Marines,63 they were the final and conclusive catastrophe for the enemy brigade: "Intensive bombing and strafing followed our unsuccessful attack at down, and our efforts to take the field are doomed to failure."

While the Battle of the Ridge was in progress, and while the perimeter was being subjected to gunfire from enemy surface craft, the newly emplaced 5-inch guns of the 3d Defense Battalion went into action for the first time. Battery C had been in position and ready for action since 1800, 10 September, a short distance east of the mouths of the Lunga River. One gun of Battery B, near Kukum, had been made ready by late afternoon of the 13th. On the same night, four enemy destroyers stood in to within 7000 yards, on a magnetic azimuth of 345 degrees. They were engaged by both batteries. Four rounds were expended by Battery B before the enemy withdrew from its range.64 Battery C continued until it had fired 29 rounds, securing at least one hit. The enemy craft then pulled out to 18,000 yards.65

During the night of 13-14 September, another sector of the perimeter was subjected to attack, perhaps launched in support of that against the ridge, although there was little evidence of coordination between the two attacking forces. The 3d Battalion, 1st Marines, in position far to the left of the Raiders' area of activity, held the innermost extension of what was known as the right, or east, flank of the perimeter. Alligator Creek, upon which this flank position was based nearer the beach, extends only a relatively short distance inland, and in the sector occupied by the 3d Battalion there was no such natural line of defense. The battalion was emplaced at the edge of a jungle, with prepared fields of fire to its front, where a wide plain had been cleared of grass by burning. The position was continuous and strongly protected by wire.66

65. Here, as at Tulagi, the lack of cranes and tractors had made it necessary to manhandle the weapons into position. Another problem beset the personnel of the battalion in the form of a high water-table. It was not possible to sink the emplacements to the proper depth because of seepage. It was therefore necessary to build them up to trunnion height. LtCol Curtis Burton in interview with the author.

WIRE PROTECTED THE 1ST MARINES' POSITIONS fronting on the grassy plain, across which the Japanese 1st Battalion, 124th Infantry delivered an attack during the Edson's Ridge battle to the west.

The Japanese 1st Battalion, 124th Infantry, attacked at midnight across the plain, against the extreme right flank, and, after being thrown back, continued the engagement as a fire fight from the jungle beyond the cleared plain. By morning it was estimated that about one Japanese battalion, plus an undetermined amount of artillery, was in position there, and it was decided to employ light tanks, 1st Tank Battalion, to clean them out. This was begun with some success, but the mistake was made of allowing repeated sorties over the same route. This, once the enemy had emplaced his 47mm antitank weapons, resulted in the loss of three vehicles.67

The fight thereupon degenerated into a fire-fight of steadily lessening intensity, which died away completely on the 16th. The enemy losses were estimated at 200 in this area.

COL MERRITT A. EDSON, whose defense of the Ridge saved Henderson Field, was subsequently awarded the Medal of Honor for his heroism and skill.

A third attack, by no means as intense as the two just described, was repulsed on the sector held by the 3d Battalion, 5th Marines, in position on the west flank, on a ridge which commanded the approaches from the Matanikau. At the inception of this attack, some worry was felt because of a lack of reserves at the threatened point, but prompt employment of artillery succeeded in driving the enemy back.68

In the Battle of Edson's Ridge, the Marines suffered casualties of about 20% of the men engaged--31 killed, 103 wounded, and nine missing--while on the ridge alone and the territory immediately adjacent to it, more than 600 enemy dead were found. Many more were killed in subsequent operations along the Lunga River, and an undeterminable number died of wounds en route to the area beyond the Matanikau. This does not include the 200-odd who were killed in the attack on the position of 3d Battalion, 1st Marines, nor the unmentioned and apparently undetermined number who fell before the 3d Battalion, 5th Marines.69

Enemy sources - in the form of documents and information from prisoners--say that abut 1500 casualties were suffered.70 The balance of the ill-fated Ichiki unit was wiped out, the 1st Battalion, 124th Infantry, and the 2d Battalion, 4th Infantry, were badly hit.

Artillery support throughout all three phases of the attacks had been provided and controlled by forward observers and liaison personnel. A forward observation post was maintained on the ridge, and fire from the 105mm howitzers was adjusted from that post. Wire communication was successful between the OP and the fire-direction center, being interrupted only when the OP was displacing rearward from its farthest forward position.71

A total of 1,992 rounds of 105mm ammunition was fired in defense of the ridge at ranges of from 1600 to 2000 yards, sometimes within 200 yards of the front lines. In defense of the other positions, the 75mm pack howitzer was used, and a total of 878 rounds was expended by the 2d and 3d Battalions, 11th Marines. Existing maps, which had not been corrected or revised since before the initial landings, were found to be extremely inadequate, since clouds had obscured the area of the operation on the original serial photo and there was no accurate knowledge of the terrain. As a result, all concentration, as well as friendly front lines, had to be "shot in".

Edson's force was replaced on the Ridge by the 2d Battalion, 5th Marines, and went into bivouac near Kukum. The 1st Parachute Battalion left the island shortly after the conclusion of the battle, and landed at Noumea, New Caledonia, on 22 September, the first unit to be evacuated from the island.72 The Raider Battalion remained on the island.

MAJ KENNETH D. BAILEY, wounded during the Battle of Edson's Ridge, subsequently killed in action on the Matanikau, was posthumously awarded the Medal of Honor for his fight on the Ridge.

Both Edson and the commanding officer of Company C, Major Kenneth D. Bailey, received the Medal of Honor for their part in turning back [the] most serious single assault of the campaign. Edson's award was given as a result of his outstanding coolness and skill under fire - a quality which permitted him to handle his forces in an intricate night maneuver while engaged in a desperately fought action. Bailey, soon to lose his life on the upper Matanikau, was awarded the medal posthumously for his leadership - painfully wounded, he stayed in action in the most exposed positions, encouraging and directing the men under him.

Chapter VI: Development of the Perimeter and Actions to the West

PATROLLING INTENSIFIED as it became evident that this was the only effective method of divining Japanese intentions under Guadalcanal jungle cover. This Marine unit is crossing the Matanikau River footbridge.
Caption: This Marine unit is crossing the Matanikau River footbridge.

Immediately following the battle of the Ridge, active patrolling from the perimeter was resumed to the south, the east, and the southwest. It had been shown once again that it was possible for a determined enemy to bring large bodies of troops practically to the Marine perimeter without detection from the air or from observation posts, and once again it was realized that the only safeguard against such movements was a program of patrolling designed to keep under constant inspection all feasible avenues of approach to the airfield.

These patrol activities ranged from short


reconnaissances carried out by small parties, to combat missions involving the use of a full battalion or more.1 Indeed, all the offensive blows struck by the Division prior to its first tentative advances to the northwest in November may be classed as patrol actions, even those which involved movement by boat to points up or down the coast, since no one of them was undertaken with the idea of altering the perimeter or increasing the area actually under occupation by the 1st Marine Division.

The Battle of the Ridge was a greater victory, perhaps, than had been realized at the moment. The large numbers of Japanese dead spoke unmistakably of a strong and well equipped force. The fact that it had withdrawn to the southward, moreover, indicated that for the moment there was to be a respite.

To verify this, and to harry the retreating enemy, a patrol of two company strength was sent out from the 1st Battalion, 1st Marines in the early morning of 14 September, just after the last spasm of the attack upon Edson's positions had subsided. Following the right bank of the Lunga River, the patrol made contact at about 1100 when it came upon a bivouac several thousand yards south of the scene of the previous night's struggle. Fire from light machine guns killed one and wounded three of Cresswell's men, and the patrol withdrew to the perimeter.

Three days later, on 17 September, a similar patrol from the same battalion consisting of Companies A, B, and Headquarters Company, with a platoon of Company D attached, followed the same route. At 1330 it found proof that Kawaguchi, badly mauled through he had been, was still full of fight. A burst of fire from machine guns cut off one platoon of Company B, in the lead, and in spite of all efforts, the remainder of the patrol could not extricate them. A fire fight continued until the group received orders from division to retire at 1600. The movement back to the perimeter was accomplished after dark, and the patrol reported three men wounded and brought back, and 18 missing in action. It was not until a week later when a third patrol was led into the area by Major Marion Fawcett that the fate of the 18 was definitely learned. They had fallen during the fire fight.2

Coming of the Seventh Marines

On 18 September, the defensive problem of the perimeter took on a somewhat different aspect, for on that date the 7th Marines (reinforced) landed, 4,262 strong, and returned to Vandegrift's control. The return of this well equipped and highly trained unit had been accompanied by vicissitudes already familiar to other units of the division. On 20 June, before plans for an offensive had begun to take shape, King had advised Nimitz by dispatch that the regiment would be returned to he 1st Division on 1 September. On 20 August, Turner issued his plan for the occupation of Ndeni, for which task he chose the 7th Marines, since the 2d Marines were currently employed at Tulagi and Espiritu Santo. Then, as we have seen above, they were diverted from this operation and sent on their way to provide the amphibious troops that MacArthur needed for the balancing of his Southwest Pacific force.

While the regiment was en route, two commanders connected with the operation come to the same conclusion, namely, that the proper place for all available combat troops at the moment was at the scene of actual fighting. On 2 September, Vandegrift sent a strongly worded dispatch to Turner, in which he pointed out that the enemy was building up his land strength, the he (Vandegrift) did not have a well balanced force and needed planes and surface craft, and that he wanted the 7th Marines turned to his command.

2. Report of Actions, 1st Battalion, 1st Marines. Entries 14, 17, and 26 September.


Ghormley, by this time, was beginning to be alarmed at the situation, as we have seen. The result of his alarm and Vandegrift's request was that the 7th Marines once more were diverted from their current objective and landed at the perimeter.

By that time also, still further units were on the way across the straits from Tulagi. On 14 September, the 3d Battalion, 2d Marines were ordered across by Vandegrift3 and two days later completed the passage. Reinforcing detachments that had been attached to the various rifle regiments began to return to their parent division units, and Vandegrift, for the first, time, was able to alter his original plans and consider expanding the scope of his operations.

In this change, he was aided greatly by the fact that Geiger could now almost guarantee him at all times an operating force of about 60 planes. The unit designations of Geiger's mixed CACTUS Air Force - Marine, Navy, and Army - by this time had begun to take on a kaleidoscopic quality that was never quite lost during the remainder of the campaign. Planes, pilots, and carrier "flights" came and went with a bewildering informality that defeats every effort to sort them out.4 The great and outstanding quality of the local aviation, however, was that with it, the defenses of Henderson Field were deepened, and the enemy, whether he came by air or by surface craft, could be met far to the north of the field, and could only reach it after having fought his way to it.

In the words of the General's Final Action Report,

This accretion of force required us to re-examine and readjust our plans in accordance with improved circumstances and in the light of lessons learned from the bitter fighting of mid-September. Ten infantry battalions and one raider battalion were now available on Guadalcanal. These were supported by four battalions of artillery, a nearly complete defense battalion, a small provisional tank battalion, and a growing air force.

Operation Order 11-42, issued on 19 September, set forth the details of a complete perimeter defense, a defense which consisted of utilizing special units for beach defense and of employing rifle battalions for the more vulnerable inland defenses. The perimeter itself was divided into ten sectors, of which seven were manned by rifle battalions. It was found to be possible, as a result of the increase

ADVANCED BASE AIR OPERATIONS, always much less formal, were carried on by BrigGen Geiger's CACTUS Air Force with an economy of means which set records even for Marine aviation.

in force, to arrive at a more satisfactory assignment of combat and administrative functions, for the nature of the beach defenses made it possible for those groups manning it to be employed in administrative duties by day and to be deployed tactically by night.

Furthermore, the concept of the perimeter was changing. Whereas the shortage of men, equipment, and supplies, together with the inadequacy of surface and air support, which had characterized the early days of the operation had dictated the policy of regarding the perimeter as both the initial and the final defensive position--and it will be remembered that two considerable battles had been fought on the perimeter--the greatly improved supply and support situation now made possible a change in that policy. The presence of an extra Marine regiment, and the knowledge that some Army ground troops (the 164th Infantry) were finally to be forthcoming, enabled General Vandegrift to contemplate a shift to a more active and aggressive type of defense.

Experience along the rivers, and particularly the experience gained on the night of 20-21 August at the mouth of Alligator Creek, indicated clearly that the initial defensive line could be extended in two directions to the Matanikau on the west, and the Tenaru on the east. In the case of the Matanikau, the immediate surroundings were such that crossings could be made only at highly localized points, and the terrain adjacent to those points afforded considerable advantage to the defending force. From its points of origin, far back in the jumbled foothills, the river flows through a deep, narrow valley, flanked on each side by steep ridges, and for the last mile of its course it becomes a deep and sluggish lagoon in a narrow, gorge-like valley. Only at a relatively short distance from the mouth do the hills flatten out in the narrow coastal plain.

An entirely different, but no less favorable, picture was presented by the Tenaru, at the opposite (east) side of the defensive positions. Here again a large river rises in the foothills, but instead of winding through precipitous and difficult country, it runs through plains land and jungle flats for almost all that part of its course which had a bearing on the problems of defense. On the far side, away from the perimeter, lies a succession of broad grassy plains, country admirably suited to the tactical deployment of troops and to the type of coordinated maneuver in which tanks and artillery could be used to greatest advantage.

Even the attitude of the commanding general toward the great difficult southward stretch of country between the inner flank extensions of the perimeter had changed. It had been seen that it was impossible to form and maintain a continuous line of defense, for the length of the sector and the character of the terrain which it crossed prevented any such development. It was rightly apprehended, also, that an enemy moving with some degree of caution could assemble large forces south of the airfield and could achieve some measure, at least, of surprise. This fear had been realized during the Battle of the Ridge.

That battle, however, had demonstrated another fact, which was that any enemy force coming into position for an attack upon that sector would have, perforce, to travel far inland and across terrain of a nature which virtually forbade the carrying of artillery or heavy crew-served weapons. The logistic aspect of such a movement presented problems far less capable of solution that were those which arose from a consideration of the defending of the area. Time-distance factors were so distorted by the chaotic nature of the terrain that planning with any degree of confidence was out of the question for an attacking force.

As it finally developed, two distinct types of defensive positions were used in defense of the sector. Along the grassy ridges to the west of the Lunga, it was possible to arrange defenses in depth, taking advantage of high bare ground along the hills. To the east of the Lunga, where the land falls to the jungle flats which border the upper reaches of the Tenaru, defense in depth was not feasible because of the sheer impossibility of cutting fields of fire for mutually supporting positions.


Here, in effect, a cordon was established, based upon a series of foxholes and weapons emplacements behind a continuous wire barrier--two parallel bands of double apron fence with trip wires between the bands. Great pains were taken to make this line self-sustaining in the event that sections of it became isolated as a result of enemy penetration. Food and ammunition were stored at the line, and small mobile groups were placed at frequent intervals for use as reserves.

Action on the Matanikau, 24-26 September

Strong patrol activity continued, as a result of which previous intelligence estimates were confirmed. There was a dearth of enemy activity to the southeast and very little of an alarming nature to the south and the southwest. In the territory among the foothills of the upper Lunga, occasional bands of survivors of the Kawaguchi detachments were moving gradually to the westward and the northwest in search of their fellows. To the west and the northwest, however, patrols found that there was evidence of gradually increasing numbers of Japanese. The same portentous kind of contacts began to be made that had preceded the battles of the Tenaru and the Ridge.

Enemy reinforcement were still being brought in. By the end of September, for example, the rest of the 4th Infantry and the entire 29th Infantry had been landed. About 600 replacements had also arrived for the badly mauled 124th Infantry, which had lost almost its entire 1st (Ishitari) Battalion in the assault on the positions of 3rd Battalion, 1st Marines.5

These reinforcement efforts were not being made without some hardship. On 21 September the destroyer Kagero was strafed by fighter planes from Henderson Field as she disembarked troops in the Kamimbo Bay area. Three days later, the destroyers Kawakaze and Umikaze were bombed and strafed at the same place, likewise by planes based on Henderson Field, and both were damaged.6 A night attack, with flares was made 22 September, on other destroyers near Visale. Damage was not determined.7

In spite of the contacts made with small enemy groups, however, and in spite of other items of intelligence brought in by patrols, there was still a wholly inadequate knowledge of the enemy situation. This was due, in part, to the fact that the enemy main bodies were far removed from the perimeter and therefore beyond the areas that could be covered by patrols. In part it was due also to the fact that heavy rain forest, such as that which covers the greater part of the island, offers almost perfect concealment from aerial observation.8 Whatever the cause, however, there was a lack of adequate intelligence, a fact that was brought out unequivocally in the following letter (quoted in part):

It can be said that we had most faulty intelligence of Japanese strength and dispositions. No orders would ever have been given for a battalion to go up to Kokumbona and patrol from there had there been any realization that there were several thousand Japanese between the Matanikau and Kokumbona. Faulty intelligence was the cause of the whole breakdown at that time.9

Colonel Griffith here had reference to an action which came as near being a defeat as anything undertaken by the Marines during the entire campaign.

The action along the Matanikau during the period of 24-26 September was planned initially as two separate, though related, operations.10 In order to disrupt whatever plans the enemy might have for gathering a strong force in the area lying between the Matanikau River and Kokumbona, a reconnaissance in force by the 1st Battalion, 7th Marines, was to be conducted from 23 to 26 September in the territory lying in the hills between Mambulo and Kokumbona. On the latter date the 1st Raider Battalion was to strike west across

HEAVY PRESSURE ON THE 1st BATTALION, 7th MARINES, made it evident that retirement would be necessary.

the mouth of Matanikau toward Kokumbona, with the idea of establishing, if possible, a patrolling base at that village.

The 1st Battalion, 7th Marines, set out from the perimeter on the 23d, which passed without incident. The D-3 Journal contains no messages from that unit until late in the evening of 24 September, when, at 2030, Lieutenant Colonel Lewis B. Puller, commanding the battalion, reported that in the afternoon he had met and engaged an enemy force in bivouac, and that, in the resulting action, which had broken off at nightfall, he had suffered casualties of seven killed and 25 wounded, of whom 18 were stretcher cases. he requested air support for continuation of the action on the 25th and stretchers for removal of his wounded. An unknown number of casualties had been inflicted upon the Japanese, who had withdrawn.11

It was apparent to General Vandegrift that evacuation of the wounded and dead would reduce the force by about 100 men--movement by stretcher being an exhausting process - and the knowledge that there was, in the neighborhood, an enemy force capable of inflicting such punishment after having been surprised, made it obvious that the battalion would have to be reinforced. It was also desirable, under the circumstances, to allow Puller - a veteran jungle-fighter of long Nicaraguan experience--to make his own decision as to continuing or withdrawing from his assigned mission.

Accordingly, at 2230, Colonel Puller was notified that, in addition to his requests for water, stretchers, and air support, an additional rifle battalion would report to him the next day, and that he was free to continue or to return, depending upon his situation in the morning.12

The action had resulted from the battalion's coming first upon a small party of enemy (an observation post of the Oka Detachment, in position nearby) on the northwest slopes of Mambulo (Mount Austen), busy at their rice fires. This group was struck and destroyed, but the noise alerted the main body, with whom contact had not as yet been made. The ensuing action continued until nightfall, when the enemy withdrew.13 It was impossible to tell what enemy casualties had been, although numerous fresh graves seen the next day indicated that the Japanese had suffered more heavily than had the Marines.

The 2d Battalion, 5th Marines (Reaves) was sent out at 0500 on 25 September in accordance with the decision of General Vandegrift. It reported to Colonel Puller for duty at 0845. With this increase in force, Puller decided to continue the assigned mission, with minor changes.14 Companies A and B of the 7th Marines therefore returned to the perimeter with the casualties, under command of Puller's executive officer (Major Otho L. Rogers) while Company C and a portion of his headquarters, together with the reinforcing battalion from the 5th Marines began the advance westward, toward the Matanikau. The night passed without incident, with the Marines in bivouac east of the river.

The force did not reach the river itself until the 26th,15 the day originally set for the completion of the first phase of the operation. Immediately upon reaching the banks of the river, it began advancing northward toward the coastal road. At about 1400,16 while moving down the valley some hundreds of yards from the mouth of the river, the main body began receiving fire from enemy mortars in position near the village of Matanikau, on the opposite bank and near the coast, and from automatic weapons. It was apparent that the ridges west of the river were held in some strength by the enemy.17
