In the wake of the Freeman Field Mutiny, the 616th and 619th were disbanded and the returned 99th Fighter Squadron assigned to the 477th on 22 June 1945; it was re-designated the 477th Composite Group as a result. On 1 July 1945, Colonel Robert Selway was relieved of the Groups command; he was replaced by Colonel Benjamin O. Davis, Jr. A complete sweep of Selways white staff followed, with all vacated jobs filled by African-American officers. The war ended before the 477th Composite Group could get into action. The 618th Bombardment Squadron was disbanded on October 8, 1945. On 13 March 1946, the two-squadron group, supported by the 602nd Engineer Squadron (later renamed 602nd Air Engineer Squadron), the 118th Base Unit, and a band, moved to its final station, Lockbourne Field. The 617th Bombardment Squadron and the 99th Fighter Squadron disbanded on July 1, 1947, ending the 477th Composite Group. It would be reorganized as the 332nd Air Expeditionary Wing.
