アッツ島の戦い
With the second combat airfield becoming operational and within striking range of the Japanese garrison on Attu, the Japanese forces on Kiska were put into an untenable situation. From its bases on Amchitka and Adak, Eleventh Air Force conducted continual bombing raids on the Japanese on Kiska and Attu. Additional long-range B-24 Liberator heavy bombers were moved down from mainland Alaskan bases to operate in the Aleutians, which enabled Air Force commanders to send the bombers with full loads to Attu, while B-25 Mitchell and B-26 Marauder medium bombers attacked Kiska several times each day. Air support for the Battle of Attu, which took place from 11–30 May 1943 was carried out primarily from Amchitka. The battle, which lasted for more than two weeks, ended when most of the Japanese defenders were killed in brutal hand-to-hand combat after a final banzai charge broke through American lines.
