Battle of Attu

The Battle of Attu (codenamed Operation Landcrab), which took place on 11–30 May 1943, was a battle fought between forces of the United States, aided by Canadian reconnaissance and fighter-bomber support, and Japan on Attu Island off the coast of the Territory of Alaska as part of the Aleutian Islands campaign during the American Theater and the Pacific Theater. Attu is the only land battle in which Japanese and American forces fought in snowy conditions, in contrast with the tropical climate in the rest of the Pacific. The more than two-week battle ended when most of the Japanese defenders were killed in brutal hand-to-hand combat after a final banzai charge broke through American lines. Background The strategic position of the islands of Attu and Kiska off Alaska's coast meant their locations could control the sea lanes across the northern Pacific Ocean. Japanese planners believed control of the Aleutians would therefore prevent any possible U.S. attacks from Alaska. This assessment had already been inferred by U.S. General Billy Mitchell who told the U.S. Congress in 1935, "I believe that in the future, whoever holds Alaska will hold the world. I think it is the most important strategic place in the world." On 7 June 1942, six months after the United States entered World War II, the 301st Independent Infantry Battalion from the Japanese Northern Army landed unopposed on Attu. The landings occurred one day after the invasion of nearby Kiska. The U.S. military feared both islands could be turned into strategic Japanese airbases from which aerial attacks could be launched against mainland Alaska and the rest of the U.S. West Coast. In Walt Disney's 1943 film Victory Through Air Power, the use of the Aleutian Islands for American long-range bombers to bomb Japan was postulated.
