A congressional investigation found that while President Truman had the obvious authority to relieve General MacArthur whenever he wanted to, MacArthur had never violated any orders given him. No court martial was convened and MacArthur retired. Though due to the intricacies of being a General of the Army, he was never administratively taken off active duty. He was instead assigned in absentee to the office of the Army Chief of Staff. He would maintain that office and rank until the day he died.
