Attu
The Battle of Attu 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. In contrast with the tropical climate in the Pacific, Attu is the only land battle in which Japanese
and American forces fought in snowy conditions.
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.
