The US heavy cruiser USS Indianapolis (CA-35) is torpedoed by Japanese submarine HIJMS I-58 northeast of Leyte at 12.02N, 134.48E. After delivering parts of the atomic bomb to Tinian, USS Indianapolis was dispatched to Guam where she disembarked men and reported for onward routine to Leyte. From there she was to report to Vice Admiral Jesse B Oldendorf for further duty off Okinawa. Departing Guam 28 July, USS Indianapolis proceeded by a direct route unescorted. Early in the morning, 0015 hours, 2 heavy explosions occurred against her starboard side forward, and she capsized and sank in 12 minutes. The ship had been hit by two torpedoes. The seas had been moderate; the visibility, good, USS   Indianapolis had been steaming at 17 knots. When the ship did not reach Leyte on the 31 July, as scheduled, no report was made that she was overdue. This omission was due to a misunderstanding of the Movement Report System. Thus it was not until 1025 hours on 2 August that the survivors were sighted, mostly held afloat by life jackets, although there were a few rafts which had been cut loose before the ship went down. They were sighted by a plane on routine patrol; the pilot immediately dropped a life raft and a radio transmitter. All air and surface units capable of rescue operations were dispatched to the scene at once, and the surrounding waters were thoroughly searched for survivors.

NETHERLANDS EAST INDIES: LOA KULU MASSACRE: After surrendering to overwhelming numbers of Japanese troops, around one hundred members of the Netherlands East Indies Army were disarmed and for a while permitted restricted freedom in the town of Samarinda , in Borneo, where most of the soldiers lived with their families. Early on the morning of July 30, all prisoners, including their families, were rounded up and taken before a Japanese officer who summarily sentenced them all to death. No reason was given as they were bundled into lorries and taken to Loa Kulu just outside the town. There they had their hands tied behind their backs and as the men and children watched, the women were systematically cut to pieces with swords and bayonets until they all died. The screaming children were then seized and hurled alive down a 600 foot deep mine shaft. The men captives, forced to kneel and witness the butchery of their wives and children, and suffering the most indescribable mental torture, were then lined up for execution by beheading. When the grisly ritual was over, the bloodied corpses and severed heads of the 144 men were then thrown down the mine shaft on top of their murdered wives and children. The horror of Loa Kulu was discovered by Australian troops who had earlier started a search for the missing Dutch soldiers. (Denis Peck)
