In the wake of the Japanese attack on Pearl Harbor and the report of the First Roberts Commission, President Franklin D. Roosevelt issued Executive Order 9066 on February 19, 1942, authorizing the War Department to create military areas from which any or all Americans might be excluded, and to provide for the necessary transport, lodging, and feeding of persons displaced from such areas. On March 2, 1942, the U.S. Army Lieutenant General John L. DeWitt, commander of the Western Defense Command, issued Public Proclamation No. 1, demarcating western military areas and the exclusion zones therein, and directing any "Japanese, German, or Italian aliens" and any person of Japanese descent to inform the U.S. Postal Service of any changes of residence. Further military areas and zones were demarcated in Public Proclamation No. 2.
