With an armistice apparently imminent in Korea the campaign to maintain certain major North Korean airfields in unserviceable condition became one of the features of naval air effort. All airfields so assigned to COMNAVFE were attacked repeatedly, cratered, and maintained under close observation to insure their continued unserviceability. In connection with this effort, CINCFE waived the previously existing requirement which had directed 48 hours notice when targets near the Manchurian border were scheduled for attack.

2 June

During a heavy gun strike in Wonsan Harbor, enemy counterbattery fire was received by the USS St. Paul (CA 73) and USS Manchester (CL 83). The Red gunners fired about 38 rounds of estimated 105 mm at the cruisers, but the shells all fell harmlessly into the water.

6 June

Despite a heavy fog hampering operations in Wonsan Harbor, USS PC 706 destroyed five enemy fishing boats on the beach at the northern end of Hodo Pando.

7 - 19 June

During this period the major effort of naval air was directed against communist front line and supporting positions to counter an apparent effort by communist forces to gain ground along the frontiers prior to a possible armistice. In furtherance of this effort three and four carrier operations were maintained. Flight operations were carried out on an around the clock basis and were not suspended for fueling operations. Replenishment ships were retained with the task force and effected what may have been the largest scale night replenishment operation ever attempted by any Navy. As a further deterrent to the communist forces in the front lines USS New Jersey (BB 62) was employed against the front line positions at the eastern front.

7 June

Typhoon "Judy", which crossed the southern Japanese island of Kyushu on this date influenced Task Force 77 operating weather for three days, causing a suspension of flight operations for half a day on the 5th, all of the 6th, and three-fourths of the 7th of June.

8 June

In the Wonsan area, three enemy shore guns fired 60 rounds of 76 mm at friendly destroyers, USS Lofberg (DD 759) and USS Bole (DD 755). No damage was experienced.

For the 2nd straight night hostile aircraft were detected in the vicinity of Chodo.

9 June

USS Boxer (CVA 21) celebrated her 59,000th landing.

In order to obtain greater fuel supply and to increase catapult bomb loads three COMNAVFE recommended that one squadron of F4U-4 in USS Lake Champlain (CVA 39) be exchanged with one squadron of F9F-5 in the unconverted USS Boxer (CVA 21). CINCPACFLT concurred in this proposal and the change was effected this date. Boxer had been the first carrier deployed with three F9F-5 squadrons aboard.

USS Bole (DD 755) had a busy day in Wonsan Harbor firing on active gun positions. Although the enemy guns were primarily concerned with the friendly islands they registered their discomfiture by pumping 13 rounds of artillery shells at Bole. The destroyer was not hit and continued to harass enemy gun positions.

The communists launched a major offensive ground campaign against the II ROK and X U.S. Corps fronts. Flinging four to eight divisions into the offensive the communists were able to gain some terrain of no tactical importance and minus rail or road facilities. By the 15th of June the enemy had suffered 16,300 killed or wounded and lost 81 prisoners. The enemy's patent disregard for human life in attaining such limited objectives at such a high cost, objectives without any military worth, offered only propaganda support for the false claim that the communists were ready to sign an armistice while "winning" the war. Despite poor weather, the navy's effort to help their comrades on the ground was a herculean one. Tremendous all out offensive air strikes were launched from USS Princeton (CVA 37), USS Philippine Sea (CVA 47), USS Boxer (CVA 21), and USS Lake Champlain (CVA 39) in support of UN ground forces. These strikes were launched with ceilings consistently lower than 1,500 feet and frequently with ceilings of 300 foot around the task force. Nightly replenishment of the task force continued throughout the period in order to sustain the increased tempo of communist slaughter from the air. The evening replenishment of Task Force 77 carried out during this period was accomplished using only minimum red lights on cargo decks and fueling rigs and with the replenishment ship masthead lights lit.

10 June

Sixty-eight F9F's from VMF 115 and VMF 311 spread napalm on a 333 building troop billeting area in the Chaeryong vicinity. Reconnaissance photos taken five days later estimated the havoc at 230 buildings destroyed and 40 damaged.

11 June

Red gunners employed in the defense of Wonsan fired an estimated 45 rounds of 105 mm at the USS Wiltsie (DD 716) and scored one hit on the starboard side of the main deck. The ship suffered numerous shrapnel holes and one 4 inch hole in the deck, but remained completely operational. There were no personnel casualties. An estimated eight guns participated in the attack on Wiltsie.

Thirteen rounds of artillery shells fell on UN held islands in Wonsan Harbor during the day, but friendly installations escaped damage.

In preparation for a possible armistice, 19,425 persons and their belongings were lifted from West Coast Islands north of the 38th parallel to southern islands. Before leaving, the inhabitants razed their villages and slaughtered their cattle.

11 - 20 June

A total of 138,400 artillery and 703,637 combined total of artillery and mortar fire fell on friendly troop positions during this 10 day period, surpassing the previous record total for any 10 day period, as well as any 30 day period.

12 June

During a heavy gun strike in Hungnam Harbor, USS Manchester (CL 83) and USS Carpenter (DDE 825) received 16 rounds of estimated 76 mm counterbattery fire. None of the enemy rounds caused damage.

14 June

In an effort to slow the big communist offensive, Task Force 77 aircraft struck at the Hasepori marshalling yard, a supply bottleneck for the Reds.

Carriers of Task Force 77 launched no less than 508 sorties today in support of friendly troops undergoing the communist ground offensive.

Wonsan guns fired 62 rounds at USS Lofberg (DD 759) and USS Bole (DD 755); and nine rounds of artillery shells on the islands. No damage was experienced.

USS Bremerton (CA 130) received four rounds of 90 mm counterbattery fire while blasting the enemy shore gun positions on the Wonsan perimeter. The enemy fire was ineffective.

Enemy gun battery Pungsam district shelled USS LST-529 off Cho-do Island, straddling the landing craft four times but scoring no hits. USS LST-529 returned fire with aft 40mm guns until opening range. The tank landing ship suffered no damage and successfully evacuated refugees from Cho-do Island later that afternoon.

15 June

Wonsan guns made a concerted effort to bag a ship today firing over 110 rounds of estimated 105 mm at USS Lofberg (DD 759), USS Bole (DD 755) and USS Current (ARS 22). Despite their extended efforts the Red gunners were unsuccessful.

Task Force 77 attack sorties totaled 403 this date, establishing a high mark for this force in the Korea action, and when combined with marine aviators, the naval air total sorties was 910 for the day.

16 June

One enemy PO-2 aircraft was shot down by an AD over front lines.

Two unidentified enemy planes dropped five bombs on POL dump at Inchon causing considerable damage. Fire ignited 97,950 93-gallon drums and 48,000 5-gallon drums of petroleum products.
