Shortly after the German invasion of Poland, beginning World War II in Europe, the 1st Infantry Division, under Major General Walter Short, was moved to Fort Benning, Georgia, on 19 November 1939 where it supported the U.S. Army Infantry School as part of American mobilization preparations. It then moved to the Sabine Parish, Louisiana area on 11 May 1940 to participate in the Louisiana Maneuvers. The division next relocated to Fort Hamilton, Brooklyn on 5 June 1940, where it spent over six months before moving to Fort Devens, Massachusetts, on 4 February 1941. As part of its training that year, the division participated in both Carolina Maneuvers of October and November before returning to Fort Devens, Massachusetts on 6 December 1941.
