Truscott took over command of the Third Army from General George S. Patton on 8 October 1945, and led it until April 1946. This command included the Eastern Military District of the U.S. occupation zone of Germany, which consisted primarily of the state of Bavaria. When the Seventh Army was deactivated in March 1946, Truscott's Third Army took over the Western Military District (the U.S.-occupied parts of Baden, Württemberg and Hesse-Darmstadt). Truscott was reassigned in April 1946 and retired from the army on September 30, 1947.
