A little about the 4th Division and the maneuvers,
"As war clouds engulfed Europe, the 4th Division was reactivated on June 1, 1940 at Fort Benning, Georgia as America began to increase the size of our armed forces. Selected to act as an experimental unit for the development of methods recently demonstrated by the German blitz through Belgium and France, the 4th Motorized Division began a three year, wide-open experiment. From August 1940 through August 1943, the division participated in the Louisiana Maneuvers, was moved to the newly opened Camp Gordon, GA where they participated in the Carolina Maneuvers, and was moved to Fort Dix, New Jersey before being redesignated the 4th Infantry Division. A movement in September 1943 to Camp Gordon Johnston, Florida gave the division realistic amphibious training in preparation for the assault on fortress Europe."
