During World War II the remote Aleutian Islands, home to the Unangax̂ (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 Unangax̂ civilians; a 15-month air war; and one of the deadliest battles in the Pacific Theater. - in: https://www.nps.gov/aleu/index.htm
A memorial overlooking downtown Unalaska is dedicated to the Unangax who were forcibly evacuated during WWII and the Aleutian villages that were never resettled. - in: http://www.alaskapublic.org/2017/06/02/75th-anniversary-of-aleut-evacuation/
