The Freeman Field mutiny was a series of incidents at Freeman Army Airfield, a United States Army Air Forces base near Seymour, Indiana, in 1945 in which African American members of the 477th Bombardment Group attempted to integrate an all-white officers' club. The mutiny resulted in 162 separate arrests of black officers, some of them twice. Three were court-martialed on relatively minor charges. One, Roger C. Terry, was convicted. In 1995, the Air Force officially vindicated the actions of the African-American officers, set aside the single court-martial conviction and removed letters of reprimand from the permanent files of 15 of the officers. The mutiny is generally regarded by historians of the Civil Rights Movement as an important step toward full integration of the armed forces and as a model for later efforts to integrate public facilities through civil disobedience.
