Text of a pamphelet from 1943 discussing the
internment relocation of Japanese from the West Coast.
During the spring and summer of 1942, the United States Government carried out, in remarkably short time and without serious incident, one of the largest controlled migrations in history. This was the movement of 110,000 people of Japanese descent from their homes in an area bordering the Pacific coast into 10 wartime communities constructed in remote areas between the Sierra Nevada Mountains and the Mississippi River.
The evacuation of these people was started in the early spring of 1942. At that time, with the invasion of the west coast looming as an imminent possibility, the Western Defense Command of the United States Army decided that the military situation required the removal of all person of Japanese ancestry from a broad coastal strip. In the weeks that followed, both American-born and alien Japanese residents were moved from a prescribed zone comprising the entire State of California, the western half of Oregon and Washington, and the southern third of Arizona.
