On August 15, Emperor Hirohito agreed to surrender to the Allied Powers. However, his commanders who continued resistance either did not hear of the surrender, or continued opposition either way. General Shikazuke Haruyama was killed in action on August 27 in the jungle of New Guinea, so Major Sugeo Hatakeyama took impromptu command of the army, as the other ranking officers had surrended. General Thomas Blamey, an Australian commander, was sent to mop up the Japanese soldiers who continued resistance.
150,000 Australians and Americans landed at Buna and Gona, while another 150,000 landed at Port Moresby; the other 200,000 were troops on the island. Their goal was to force the surrender of the Japanese troops on the island. Hatakeyama intended to surrender, and did so at Wabag, along with 50,000 troops. The other 50,000, led by Captain Haruyori Hitoshi, surrendered at Lae, but 1,000 fought on and 600 were killed in the Second Battle of Lae, which took place on September 1. A day later, the final Japanese surrender took place, and all resistance crumbled in the last battle of World War II.
