This series documents Babcock's service in the U.S. Army from 1894-1937. The bulk of the collection consists of Babcock's memoirs, detailing his military service at home, in the Philippines during the Philippine-American War and in France during the waning months of World War I. Included are handwritten drafts of his memoirs and the first part of his typed manuscript, titled From this Generation to the Next; letters from the War Department documenting his military service; maps to be included with his book; a typed memorandum written by John Breckinridge when he was a Captain in the 5th Cavalry; a photograph album documenting the Third Army Composite Regiment and the victory parades at the end of World War I; and photographs of the 22nd Infantry in Montana in the late 19th century.
