The Gila River War Relocation Center was an American concentration camp in Arizona, one of several built by the War Relocation Authority (WRA) during the Second World War for the incarceration of Japanese Americans from the West Coast. It was located within the Gila River Indian Reservation (over their objections) near the town of Sacaton, about southeast of Phoenix. With a peak population of 13,348, it became the fourth-largest city in the state, operating from May 1942 to November 16, 1945. Internment The rationale for internment was brought on under the pretext of sabotage of the West Coast by the large Japanese American population. Immediately following the attack on Pearl Harbor, President Franklin D. Roosevelt issued Executive Order 9066. This order was Roosevelt's authorization to hand authority to the Secretary of War and military commanders to designate areas to detain people living in the United States whom may be a threat to the country and its interests. Though it never specifically named Japanese Americans (or anyone of Japanese ancestry) to be detained, it was outwardly implied due to the outbreak of war with Japan. The Secretary of War was also told to supply accommodations to people who are held by the government. The order stated: "The Secretary of War is hereby authorized to provide for residents of any such area who are excluded therefrom, such transportation, food, shelter, and other accommodations as may be necessary". The order also gave authority of the prescribed areas to the Secretary of War ahead of other departments in the government and allowed the use of federal troops to enforce compliance with government rules in those areas. Placed in command of issuing the forced removal of Japanese Americans from their homes and businesses in the West Coast was commander of the Western Defense Command Lt. Gen. John L. DeWitt. The internment camps were hastily constructed within a few months after the issue of the order. Living quarters across all camps resembled military style barracks as they were constructed from military surplus equipment. Living space was generally tight and incredibly cramped among families. The forced removal of Japanese Americans from the "affected areas" of California, Oregon, Washington, and Arizona started from April to May 1942. Families were given just under one week to get their personal and professional affairs in order. As a result, individual families lost thousands of dollars from having to hastily sell off
