The Order for Internment of Japanese Americans in San Francisco was issued on April 1, 1942, by Lieutenant General John L. DeWitt of the Western Defense Command and Fourth Army Wartime Civil Control Administration in California. As a result of the order, persons of Japanese descent, both U.S. citizens and noncitizens, were evacuated from their homes in San Francisco, ordered to report to a Civil Control Station, and eventually transported to various internment camps located largely in the American West for most of the duration of World War II.
