Tenty en P-51's are missing. 421 B-29's bombed Osaka, 12 hit other targets, 45 have not reported. Bombing was visual and by radar, with results unobserved to good and excellent., Eney aircraft opposition was nil to moderate, except that the 313th Wing reported fifty attacks from seventy-five enemy aircraft. No claims of enemy aircraft destroyed. Ten B-29's lost - one to enemy aircraft, two ditched on way up, two collided at the assembly point and five are unknown. Eighty-five planes landed at Iwo. Five hundred B-29's, escorted by 96 P-51's,are scheduled to repeat the Osaka incendiary attack on the Third, at 1215(K). Takeoff at 0400(K). Kyushu: Task Force 38 fighters are scheduled to sweep southern Kyushu air- fields tomorrow, and may repeat on the Third. BoMCoa 21 plane reported a radar contact with a large convoy in Kii Suido. USS DRAGONNET recovered two survivors 150 miles south of Honshu. Nansei Shoto Yesterday, only one raid closed the Okinawa area and three planes were shot down.: Our air attacks to the north were weathered but Task.Unit 32.1.3 attacked the Sakishima Gunto with thirty-nine tons and 419 rockets, sinking four boats, and losing one VT. Two F4U's and three P-47's are missing from the 30th, and two F4U's collided on the 31st, both being lost. Close support included 140 sorties (94 tons, 637 rockets, four Napalm). TEM's dropped food and water to front bases. On 31 May, 256 day fighters and 26 night fighters of the TAF were in commission (out of 364 and 42 present). Better weather permitted increased Naval air and ground activity. Raids were light yesterday, and no damage sustained by out ships. In viewiof prospective enemy air attacks with the advent.:of better weather, Iheya Shima landing was postponed to the Third. Both groups of Task Force 38 are in the operating area today. Task Group 38.4 is scheduled .,to launch a long range fighter sweep over southern Kyushu fields.

CURRIER (DE 700) rescued twelve B-29 survivors north of Iwo. On Okinawa, in spite of bad weather and adverse terrain conditions, the Japs Shuri position has been broken up and the 10th Army is driving and realigning its Divisions towards the south end of the Island. Since the beginning of the present rainy spell, the eleven inches of rain which has fallen has made many supply roads impassable. This has resulted in the diversion of some troops and equipment from airfield con- struction to repairing roads in order to most fully exploit our present break- through. The 6th Marine Division drove south to the bank of the Kokuba river seizing high ground in its advance. Chief resistance came from hills to the north of Kokuba Town. Patrols have crossed the river and are probing to the south. There is considerable Jap activity reported between Naha airdrome and Naha Ko. The 1st Marine Division completed the capture of Wana hills and began the mopping up of Shuri. Considerable enemy material was captured with only scattered enemy contacts in this area. The Division drove south 2000 yards to hills overlooking Naha - Yonabaru road against moderate resistance. The 24th Corps is now reorganizing and beginning to shift the Z-A of the 96th Infantry Division to the south where it will move to the west of the 7th Division. The 96th completed the occupation of all ground in its former Z-A. The 7th Infantry Division swung all its units to the south and drove a wedge further into the Ozato hills. Stubborn resistance was encountered in the ridge country around Ogusuku, but the Jap defenses are not as elaborate as those formerly encountered. However, the remainder of the hills held by the Japs in this sector are all ideally situated for mutually supporting defensive fires. Masses of civilians are reported living in caves on the Chinen Peninsula. Indications at present are that the Japs are preparing their final line of resistance across the island from Itoman eastward to Hanagusuku.

Three were killed and nineteen wounded, five seriously. One truck was des- troyed and seven damaged, sixty barrels of diesel fuel were destroyed and several tents were damaged. Bogeys were first picketkup at 150 miles and 21,000 feet. P-61's made radar contact but were unable to close because of the high speed of the enemy aircraft. Visual contact with "balls of fire" may indicate jet propulsion was used to get away. Chichi: Eight P-51's attacked. Palau: Sixteen F4U's attacked. Sonsoral: Four F4U's attacked. Truk: Photos showed no change in airfields or aircraft present. Four air- craft were operational and four not. Param was not operational but other fields were. Southwest Pacific Formosa: Yesterday, 116 B-24's attacked Taihoku with 316 tons, destroying most of the buildings in the target area, including the Army and Navy headquarters. One hundred P-51's and P-38's destroyed fourteen locomotives and damaged a number of locomotives, railroad cars, trucks, and busses. Twenty-four B-25's achieved good destruction at Giran Town. Tomorrow, two groups of B-24's attack Kiirun installations, and two other groups attack Hozan toxic gas storage. Eighty P-38's and P-51's will strafe targets of opportunity. Philippines: Yesterday, 120 A-20's and 140 P-51's were among the 350 planes providing Luzon ground support. The Cagayen Valley and Balete Pass were heavily hit.

Three 5thAF blind B-24's sank one and probably sank a second medium AK off Shanghai. Enemy Submarines No further contacts reported. Information recieved from PhilSeaFron about contact on the 29th 200 miles east of Leyte. PCE made contact and was challenged by sonar. PCE re- plied, but maintained contact. Two hours later the PCE challenged with new recognition signals but received incorrect reply. Simultaneously information was received from ComPhilSeaFron that no friendlies were in the area, and attacked immediately. r : , i A l 5',';iAW 16S» :2;<by, &',',:" S., . , ; (Cont Id) Another PCE joined the hunt, which continued for about three more hours, idth contact being gained and lost intermittently.
