Inter-war years thumb|Patton as a temporary colonel at Camp Meade, Maryland, 1919 Patton left France for New York City on 2 March 1919. After the war, he was assigned to Camp Meade, Maryland, and reverted to his permanent rank of captain on 30 June 1920, though he was promoted to major again the next day. Patton was given temporary duty in Washington D.C. that year to serve on a committee writing a manual on tank operations. During this time he developed a belief that tanks should be used not as infantry support, but rather as an independent fighting force. Patton supported the M1919 design created by J. Walter Christie, a project which was shelved due to financial considerations. While on duty in Washington, D.C., in 1919, Patton met Dwight D. Eisenhower, who would play an enormous role in Patton's future career. During and following Patton's assignment in Hawaii, he and Eisenhower corresponded frequently. Patton sent notes and assistance to help Eisenhower graduate from the General Staff College. With Christie, Eisenhower, and a handful of other officers, Patton pushed for more development of armored warfare in the interwar era. These thoughts resonated with Secretary of War Dwight Davis, but the limited military budget and prevalence of already-established Infantry and Cavalry branches meant the U.S. would not develop its armored corps much until 1940.
