Patton  reverted to his permanent rank of Captain in the Regular Army

On 30/06/1920, George S. Patton Jr. reverted to his permanent rank of captain in the Regular Army as part of the post World War I demobilization and reduction of temporary wartime ranks. During the war, Patton had served in the Tank Corps and held temporary promotions, including lieutenant colonel and later colonel, while commanding tank formations in France. With the Army transitioning back to peacetime strength in 1920, many officers returned to their prewar permanent grades, including Patton. Following the reversion to captain, Patton continued serving in the reorganizing Army while tank units were consolidated and placed under infantry control. In the months that followed, further adjustments occurred as wartime commands were dissolved. Later in 1920, he relinquished command of the 304th Tank Brigade at Camp Meade, Maryland, and subsequently moved back into cavalry assignments. The demobilization period marked a temporary step back in rank before his later promotion to major during the early interwar years.
