For the islands, in any event, the days of U.N. occupation were numbered by the approaching armistice. The resumption of plenary sessions on 26 April, which followed the exchange of sick and wounded prisoners and ended a recess of 199 days, ushered in a period of progress which, in comparison with what preceded, could only be described as extremely rapid. By 8 June the thorny question of repatriation had been settled and hopes again rose high.
Since the armistice would prohibit further removal of the inhabitants of the northern islands, CincFE on 12 June directed the outloading of all civilians and all excess supplies from the Wonsan islands and from Yang Do. On the west coast, following the updating of plans, the evacuation of partisan forces, their dependents, and other refugees from islands north of the parallel was begun. In the east the dimensions of the problem were small, but in the Yellow Sea this last tragic displacement brought the departure, after their cattle had been slaughtered and their dwellings razed, of 19,425 persons from the islands above the demarcation line.
Although the line mapped and agreed to in November 1951 remained acceptable to the United Nations Command, the Communists insisted on renegotiation. Reasons for this attitude had for some time been evident in continued enemy troop and vehicle movement and in ostentatious stockpiling of supplies, and on 10 June anticipations were fulfilled as a heavy attack was pushed down the valley of the upper Pukhan against the ROK II Corps. The local collapse which followed required a considerable reshuffling of units on the part of Lieutenant General Maxwell D. Taylor, USA, who in February had relieved General Van Fleet at Eighth Army. But by the 18th the front had been stabilized, at the cost of a few miles of inhospitable terrain above the Hwachon Reservoir and of a little ground on the east coast. As the Chinese impetus declined hopes rose again, only to be dashed by an entirely unexpected development.
At Panmunjom General Harrison and his aides had for months been walking the knife edge between Communist obduracy and South Korean intransigence. Chinese and North Korean disinclination to admit reluctance on the part of their nationals to return to the Communist paradise found its counterpart in the unwillingness of the Rhee government to accept any armistice at all and so forego the last chance of forcible Korean unification. The signing on 8 June of the final agreement on repatriation had been followed by threats and fulminations from the ROK government, and by a period of tension in its relations with the U.N. Command.
In this crisis President Rhee found himself in a strong position. Not only did he control the territory of South Korea, the theater of U.N. operations, but he also controlled, in the ROK Army, the largest single contingent of anti-Communist forces, well-trained, well-equipped, 15 divisions strong, and manning two-thirds of the battleline. Given his fierce opposition to an armistice, the possibility that he might order these forces to attack, independently and in defiance of the U.N. Command, raised the specter of a three-cornered conflict within the peninsula, and of a situation of almost unimaginable complexity.
This he did not do, but on 18 June, without warning and despite prior assurances, the Korean government engineered a mass escape of upwards of 25,000 anti-Communist prisoners, in the apparent hope of causing a Communist break-off of negotiations. The result was an interruption of plenary sessions at Panmunjom, an embarrassing period of Communist harangues, uncertainty as to the security of U.N. forces in Korea, and apprehension as to what might happen next. Again, as on the outbreak of war three summers before, more strength was urgently needed. Again help came by sea.
To the normal commitments of Task Force 90, spring had added a variety of tasks. In April the exchange of sick and wounded prisoners had been carried out; in May two landing exercises had been held, beach surveys continued, preparations for island evacuation begun, and a lift of LCVPs made to the French in Indo-China, where another war was in progress and where, a year later, another demarcation line would be drawn. These responsibilities were increased in June as the result of floods in southern Japan, which imposed requirements for evacuation, relief, and for shipping to replace disrupted land communications. At the same time the apparent imminence of the armistice made it necessary to be ready on short notice to repatriate large numbers of enemy prisoners.
In preparation for the movement of almost 100,000 enemy personnel, a task group of 2 APAs, 6 AKAs, 20 LSTs, and minor units had been assembled, although at the cost of delaying the scheduled return of a number to the United States. On 12 June Task Force 90 was alerted for this operation, all units were placed on 24-hour notice, and ships were ordered to Pusan for installation of wood and wire cribbing which would permit the movement of fractious prisoners in manageable groups. Eleven LSTs and one AKA had been fitted with these cribs when there arose the wholly new requirement of a major emergency troop movement.
On 21 June, three days after the ROK release of prisoners, CincFE ordered the immediate airlift of the 187th Airborne RCT to Korea; two days later 2,100 soldiers and 1,500 tons of gear had been flown in by the Air Force and three LSTs and two LSMs were bringing in the heavy equipment. On the 26th orders were received to lift the equipment of one RCT of the 24th Infantry Division from Japan to Korea; shortly CincFE alerted the entire division for movement by air and sea; by 2 July some 4,000 troops had been flown across, other units had been added to the planned movement, and the emphasis had shifted from air to surface transport. In anticipation of instructions to redeploy the division, Rear Admiral Walter E. Moore, CTF 90, now ordered the removal of security cribs from his amphibious shipping; on 3 July, following receipt of orders, he dispatched three task units to Japanese embarkation ports.
These operations coincided with the centenary of a memorable event, for it was in July 1853 that Commodore Perry had entered Tokyo Bay to attempt the opening of Japan. For the Black Ships Festival, staged by the Japanese in celebration of the anniversary, Task Force 90 dispatched an AKA to Shimoda, long the residence of Townsend Harris, first American consul in Japan, and an APD to Kurihama, where Perry first set foot on Japanese soil. But even this limited representation was hard to spare, for the 14th of July, the centenary of Perrys reception at Kurihama by the Prince of Idzu and the Prince of Iwami, found his descendants in the gray ships of the Amphibious Force working under heavy pressure.
The movement of the 24th Division, so suddenly called for, required not only the diversion of all available amphibious shipping but the requisitioning of LSTs and cargo ships from MSTS; numerous modifications to CincFEs plan had brought confusion and a communications overload; weather and the lack of adequate harbor facilities forced some extemporization in loading; at one port difficulties with Japanese customs officials bizarrely delayed embarkation. By 9 July, nevertheless, one RCT was in Korea and the others were loading, when suddenly the situation was complicated by a whole new series of directives.
The double requirements of the Korean crisis and of the impending armistice, with its prohibition of further reinforcement, now produced an eruption of orders from Supreme Headquarters. On 13 July CTF 90 was instructed to transport the Armys 2nd Amphibious Support Brigade, an amphibious tank battalion, and elements of Naval Beach Group 1 from Japan to Korea. Two days later, as embarkation of these units was beginning, came orders for the movement of a regiment from Pusan to Koje Do. On the 16th, as this lift was commenced, as the last elements of the 24th Division were sailing for Korea, and as loading of other units was continuing in Japan, transfer of a second regiment from Koje up the coast to Sokcho was ordered. On the 17th there came an emergency call to move a battalion from Cheju Do to Inchon, and on the next day, to complete this planners nightmare, there arose the possibility of further redeployment of elements of the 24th Division.
One day before the anniversary of Perrys landing, and while these hasty maritime movements were in progress, the Chinese attacked again, in greater strength than in the month before. Whether this second blow had been long planned, and coordinated with peace table procrastination, or whether it was an afterthought intended to chastise a belligerent Syngman Rhee remained obscure. Again the blow fell on ROK forces, this time in the area south of Kumsong and just west of the June breakthrough, where four divisions were thrown against the junction of IX Corps and the ROK II Corps. Again there came collapse, followed by the development of a fluid situation and accompanied by pressure on the east coast strip. In response to the new emergency General Taylor moved two American divisions into the gap and brought reinforcements forward from Pusan; by 17 July U.N. forces were counterattacking; by the 20th some lost ground had been regained and a new line established which would be held until the armistice. Again some miles of mountain territory had been given up, again Chinese casualties were thought to have been extremely heavy. But the weight of the attack and the temporary disorder which ensued had brought a final period of frantic activity on land, at sea, and in the air.
Fire support off the eastern shore had been stepped up in early June when Communist seizure of Anchor Hill, a key ROK position south of Kosong, ushered in a period of heavy fighting. Two destroyers and the heavy cruiser Saint Paul were busily at work, and New Jersey was sent in to provide, for the first time since February, 16-inch gunfire at the bombline. Although the war against the railroad continued, as did the operations at Wonsan, the center of action in the final weeks was at the battleline, where one destroyer remained permanently on station, backed up for 13 days by New Jersey, and at other times by Manchester, Bremerton, or Saint Paul, Ammunition expenditure off the bombline in July totalled more than 6,000 rounds.
So, as the end approached, the gunnery forces on the eastern shore were back where they had been at the beginning, and the task that fell upon Rear Admiral Clarence E. Olsen, CTF 95 for the last five months of the war, was the task that had faced Admiral Higgins. The emphasis on interdiction of supply and transportation, strong during the period of stalemate, had given way at the last to the requirement of again supporting ROK forces on the coastal road.
For the naval aviators, as well, a cycle had been completed, and wars end found them back at the job that had once confronted Valley Forge and Triumph. Again the enemy was attacking; again the carriers, now four Essex-class ships plus a light unit in the Yellow Sea, were supporting the ground armies under the control of JOC. Some differences had indeed come with the passage of time: representation at JOC had been institutionalized and communications improved; movement from coast to coast and retirement for replenishment had long since been given up; the risks of air and submarine attack had been accepted, the advantages of mobility and surprise forgone, and the force, with its replenishment ships, was operating as a permanent air base in 39°N 129°E.
Upon this air base, upon its flying personnel, and upon the Logistic Support Force, the events of the final weeks imposed severe demands. Early in June Eighth Army called for 48 close support sorties a day, and for a large additional effort in Cherokee Strikes. On the 6th orders were received to put the entire piston-engined effort into the support of ground forces, while dividing the jets between Cherokee Strikes, road sweeps, and reconnaissance. Late in the month the lull between Communist attacks brought a limited revival of interdiction, but on 14 July Commander Seventh Fleet put all propeller planes back into support of the armies. In the last five days three very large raids were made against seven enemy airfields in the eastern half of North Korea.
With this final period of emergency there developed the most intense flight operations of the war. On 11 June, the day after the opening of the first Communist offensive, Princeton joined Philippine Sea and Boxer on the line, and two days later Lake Champlain, fresh from the Atlantic Fleet, reached the operating area. Four-carrier operations were continued through the 19th, and three carriers were kept on station until the 27th. On 14 July, with the second enemy breakthrough, a third carrier joined the force, and on the 17th the fourth, and so it continued until the end of the war.
Flight operations were hindered by the usual weather difficulties of the Korean summer. In the interior mountains the monsoonal air masses condensed into heavy fog and rain; at sea, fog and low overcast prevailed. For Task Force 77 the period was marked by a continuous search for clear areas, and by the conduct of full-scale operations with ceilings down to 100 feet and visibility of only a mile and a half. Despite this remarkable performance a large proportion of scheduled sorties was weathered out; despite these cancellations new marks for carrier operations were repeatedly set. The June record of 554 sorties flown on the 13th went by the board in July, with 592, 600, and 746 on three successive days. Total sorties rose steadily from 4,343 in May to 6,423 in July; close support sorties went up from 256 to 1,690; aircraft ordnance delivery rose from 2,835 tons in May to 4,606 in the final month.
So massive an offensive called for hard work from all hands, and for an heroic effort on the part of the Logistic Support Force. On 9 June fueling days were abolished, and from that date nightly replenishment, carried out in a mixture of fog and darkness that often required the use of towing spars and searchlights, continued to the end of hostilities. Owing to the coming of the jet airplane and to the increased bomb-carrying capacity of carrier attack planes, the requirements far exceeded anything accomplished or even contemplated in World War II. The increased expenditure of ordnance strained the capabilities of the ammunition ships; the consumption of aviation gasoline, which for a time reached 9,000 barrels a day, forced the recall of an oiler from other scheduled operations. Yet somehow all needs were met.
On men and machinery alike the strain of these final weeks began to tell, until as time went on bad weather came to seem almost a godsend. For the aviators the working day was a long one: good weather or bad, flying or not, they were on the alert and under strain; when the weather was operational the average jet pilot spent some four hours flying and another five in preparation, while propeller-plane pilots were airborne almost seven hours a day. When twilight brought an end to the long flight schedule it was time to go alongside the waiting replenishment ships, pass lines and hoses, and fuel and load far into the night. Here the immediate impact was on the ships companies, who after arduous days had to manhandle and stow large quantities of stores and ammunition, but the pilots suffered too, their sleep disturbed by the clanking of handling machinery on the hangar deck.
Under such pressure, maintenance suffered and gear began to fail. Electronic equipment became temperamental, Lake Champlain experienced breakdown of both catapults, Princeton was out for a few days with shaft vibrations, and Philippine Sea had similar troubles. These casualties to her sister ships made it necessary to hold Boxer on the line long after her scheduled date of departure, with the result that on 23 July she set a new fleet record with her 61,000th landing.
In this situation something had to give, and what gave was a plan for intensified night work which had been developed in May. At long last it had seemed possible to put air operations on a 24-hour basis, by transferring all night-configurated aircraft to Princeton and providing her with a small screen for independent night operations. But the May casualty to her shafts forced postponement of the scheme, and the subsequent need for maximum effort prevented the assignment of a carrier to night work only. So heavy, indeed, was the daytime schedule, that ordinary night heckling was first diminished and then discontinued, and the hours of darkness were conceded to the enemy.
Nevertheless night brought one triumph. Beginning in April the Communists had cast further doubt upon the virtues of modern design by the employment of fabric-covered training planesPo-2 biplanes, or Yak-18 monoplanesin a series of night air raids against the Inchon-Kimpo-Seoul area. Employed either singly or in masses of a half-dozen or so, these ancient 80-knot floaters, too low for antiaircraft fire and too slow for jet interceptors, for two months flew with impunity through the interstices of the air defense organization, damaging parked aircraft, burning a fuel dump, shaking up the residences of the President of Korea and of the gentlemen of the press, and causing generalized confusion and frustration. But in June a detachment of Corsair night fighters was sent in from the fleet, and within a month Lieutenant Guy P. Bordelon had disposed of five of the intruders, to become not only the first ace in this particular category but the Navys only ace of the Korean War.
The enemy offensive of June and July gave the close support control system its first real test since the beginning of the stalemate. As before, the system of pre-planning strikes proved useless in emergency; as before, requests for help could not be promptly answered. Although communications capacity far exceeded that of 1950, this improvement was more than offset by the vastly increased sortie capability: the close support request net clogged almost at once, and despite resort to extemporized and non-doctrinal direct communications, strikes followed requests by as much as 17 hours. Again, as in the summer of 1950, the control system collapsed as JOC duty officers, remote from the situation but wishing to help, rammed aircraft in large numbers into the threatened sectors. Once more the lack of forward air controllers below the regimental level put the main responsibility on the Mosquitos which, in the fluid situation, once more demonstrated their inability to keep track of friendly positions and important targets. Inevitably, therefore, rather than hitting troops in the open and on the move, close support and Cherokee Strikes attacked supply and billeting areas, gun positions, and trenches, and much waste ensued through jettisoning of ordnance.
These difficulties, experienced for the first time by the personnel involved, although not for the first time in Korea, were compounded by the adverse weather. Large-scale Cherokee operations, sufficiently problematical in themselves, were forced by reduced visibility to operate under ground radar control. In June 577 sorties, some 30 percent of Task Force 77s support effort, were so employed, bombing in level flight from altitudes between 10,000 and 15,000 feet, and by July this was the rule rather than the exception. In their turn the radar facilities became overloaded, and many flights had to be diverted to secondary targets, or directed to dump their loads somewhere north of the bombline.
This situation, which would have scandalized the explosive Ewen, surprisingly seems to have brought little complaint from Navy commanders. A year on interdiction had been followed by a time of only token close support, and this, taken with the rotation of carrier and air group personnel, had permitted interests to change and skills to wither. With strike results unavailable or unassessable, the magnitude of the effort tended to be emphasized, and maximum support of Eighth Army became a trucking operation in which, as often before in air warfare, statistics of sorties flown and ordnance dropped acted to conceal the central question of whether the drops hit anything worthwhile.
Only the Marines still chafed under a system, incapable of effective operation in the fluid situations where it was most necessary, whose failures were then used to support the doctrinal position that close support was an uneconomic use of air strength. But this chafing was largely theoretical. No very heavy attacks were thrown against the division which, with the bulk of its support supplied by the Marine Aircraft Wing and controlled at battalion level, found itself in a reasonably satisfactory situation, and good use was made of the final months in working out techniques for searchlight-directed night close air support.
For the Wing, too, the situation was improved. Relations between the Marine liaison officers and their Air Force colleagues at JOC had become exceptionally harmonious, and in February the Commanding General had at last regained operational control of his own squadrons. But the Marines final views on the Korean situation made no bones about the inadequacy of prevailing concepts, the inferior quality of close support rendered the armies, and the unwieldy, inflexible, and unsatisfactory methods of control which resulted from over-centralization, inadequate communications, and the lack of forward ground controllers. Still, the Marine Aircraft Wing had done its best, and if it had been unable to make experience prevail over theory, it had solid accomplishments to show. Throughout the war the Army had demonstrated its great appreciation of such Marine support as it could get; Marine night fighters had proven in certain respects superior to all others in the theater; a Marine pilot on exchange duty with the Air Force had become a jet ace; following the armistice the MAG 12 softball team became the champions of the Fifth Air Force and subsequently, disguised in Air Force uniforms, went onward and upward to become FEAF champions in September.
So, with the emergencies of the final weeks, the war had come full circle, and the ships and aircraft of Naval Forces Far East were back at the tasks of 1950. Within the naval service at large another cycle was also ending. In the expansion of the past three years, priority had been given the operating forces; the shore establishment had remained undermanned, and CoinNavFE had long been hoping for an increased allowance of personnel. But here the truth expounded by Clausewitz, that war is but the extension of politics, was once again brought home. As the Chinese were mounting their last offensives, proposals were being made in Congress for reduction of the armed forces, and a May dispatch from CNO had directed a 10 percent reduction in complement for shore activities.
But at last the end was at hand. On 19 July, with the halting of their final offensive, the Communists again evinced a willingness for progress, and on the morning of the 27th the armistice was signed to take effect that evening. The final line of contact ran from west of the Imjin River northeastward through the Iron Triangle, east to the headwaters of the Soyang River, and thence northerly to the coast below Kosong. On both shores, according to the agreement, islands beyond the demarcation line were to be evacuated by the U.N., with the exception of Paengnyong Do and the others of the Sir James Hall Group, and of Yonpyong Do and U Do off the mouth of Haeju Man.
For Task Force 77 the final day involved strikes on northern airfields; at Wonsan Bremerton and Saint Paul fired the last missions; the Amphibious Force busied itself in preparation for the repatriation of prisoners. At 2200, as the troops came out of their holes across the Korean peninsula, the ships in Wonsan harbor turned on their lights. On the harbor islands, on Yang Do and Nan Do in the east, and on Cho Do and Sok To in the west, the garrisons began to demolish their installations and pack their bags. Three years, one month, and two days after the North Korean Peoples Army had burst south across the parallel the war was over. Aggression had been repelled; Korea, like the rest of the world, remained divided.
If armistice there was, it was an uncertain one. Communist violation of provisions regarding reinforcement commenced almost at once; beyond the demarcation line the Neutral Nations Supervisory Committee was frustrated in its activities; mens lives were still at hazard. Up by the Yalu on the last day of action an Air Force fighter pilot had destroyed a twin-engined transport. The aircraft turned out to have been Russian; the event shortly produced a diplomatic protest, and still more quickly a reaction in another sphere. At 0615 on the 29th an Air Force RB-50, flying an easterly heading over the Sea of Japan, was shot down by Soviet MIGs some 30 miles south of Cape Povorotnyy. All but one of the crew parachuted into the sea, where during the afternoon several were sighted by low-altitude search planes, as were a number of Soviet ships and aircraft. In the afternoon Navy assistance was requested, and at 1745 Task Force 77 launched 13 aircraft to search to the northeast. At 1900 rescue ships were called for and a force composed of Bremerton and five destroyers headed north at speed. At 0300, as this group was approaching the area where survivors had been sighted, two night fighters were sent up from the carriers, to be followed by other aircraft throughout the day. Spread out in scouting line and with a helicopter on each flank, Bremerton and the destroyers swept the waters off the Russian doorstep throughout the 30th, covering an area of 3,300 square miles. But despite all efforts only a single survivor could be found.
So ended in a shaky truce Americas first 20th-century war for limited objectives. To some in the armed services, Army, Navy, and Air Force alike, this ending, with little permanently resolved, was less than satisfactory. Something seemed to have been forgone when truce negotiations with a beaten enemy had been commenced; the repeated concessions at Panmunjom had appeared unnecessary; and while none, perhaps, could satisfactorily define the victory he would have liked to gain, the Communist employment of negotiations as a shield for reinforcement and a forum for vituperation seemed infinitely repugnant.
But for this too there was a precedent. To the first John Rodgers, the peace of 1805 which ended the war with Tripoli was so distasteful that he offered to ransom the prisoners with funds raised from the officers of the squadron, if only the war could go on. Yet it may be that such an attitude, whether in Korea or in Tripoli, reflects an excessive emphasis upon the paper provisions of a settlement and an underestimation of the more substantial factors which govern the relations among nations. Unsatisfactory the Treaty of 1805 may well have been, but throughout the 19th century the United States maintained, in its Mediterranean Squadron, a body of armed force appropriate to the situation, and little more was heard from the Bashaw of Tripoli.
