64th Cavalry Division (United States)

Lieutenant Colonel Steven Clay writes that the division was "constituted 15 October 1921, allotted to the First and Fifth Corps Areas, and assigned to the Fifth Army.

The division [headquarters] was initiated 22 October 1921 at the Post Office Building in Lexington, KY, by Lt. Col. Richard W. Walker.

The division HQ was moved to Louisville, KY, on 14 March 1922 to provide a more central location for ..the cavalry units in the Fifth Corps Area.

Instead, the members of the division (minus the 158th Brigade) reinforced [Regular Army or National Guard] units to bring them up to wartime strength in officers or by acting as umpires.

The 1940 maneuver in Wisconsin was the division’s last major training event, for although the 64th was not officially disbanded until [30] January 1942, it had almost ceased to exist by then.
