During World War II the remote Aleutian Islands, home to the Unangax^ (Aleut) people for over 8,000 years, became a fiercely contested battleground in the Pacific. This thousand-mile-long archipelago saw invasion by Japanese forces, the occupation of two islands; a mass relocation of Unangax^ civilians; a 15-month air war; and one of the deadliest battles in the Pacific Theater.
