In February 1942, Lt. Gen. John L. DeWitt, Commanding General of the Western Defense Command, requested authorization from Secretary of War Henry L. Stimson to evacuate "Japanese and other subversive persons" from the West Coast area. On February 19, President Franklin Roosevelt signed Executive Order No. 9066 authorizing the Secretary of War or any military commander to establish "military areas" and to exclude from them "any or all persons. A month later, President Roosevelt signed Executive Order No. 9102 establishing the War Relocation Authority, which eventually operated the internment camps. Roosevelt named Milton Eisenhower, brother of the future president, to head the WRA.Just a reminder, to those who think Henry Stimson and FDR were "progressive".
Without a murmur of dissent, the Congress quickly affirmed Executive Order 9066 with the passage of Public Law 77-503.
Beginning in March, the Army organized the evacuation of some 77 000 U.S. citizens of Japanese origin ("Nisei") and 43 000 mostly older Japanese citizens ("Issei") from California and parts of Washington, Oregon and Arizona.
Posters appeared the length of the West Coast ordering the Japanese to evacuation points. "Instructions to all persons of JAPANESE ancestry," read the bold headline on a typical poster. The text read: "All Japanese persons, both alien and non-alien, will be evacuated from the above designated areas by 12:00 o'clock noon Tuesday, April 7, 1942." The evacuees were told to report for internment with bedrolls and only as much baggage as could be carried by hand. (A postwar survey showed that 80 percent of the privately stored goods belonging to the interned Japanese were "rifled, stolen or sold during absence.")
