Army of Georgia
Following Gettysburg, Schurz's division was deployed to Tennessee and participated in the Battle of Chattanooga. There he served with the future Senator Joseph B. Foraker, John Patterson Rea, and Luther Morris Buchwalter, brother to Morris Lyon Buchwalter. Senator Charles Sumner (R-MA) was a Congressional observer during the Chattanooga Campaign. Later, he was put in command of a Corps of Instruction at Nashville. He briefly returned to active service, where in the last months of the war he was with Sherman's army in North Carolina as chief of staff of Henry Slocum's Army of Georgia. He resigned from the army after the war ended in April 1865.
