Barnes joined the Royal New Zealand Air Force in 1940, and trained in Canada.[2] He qualified as a navigator and bomb aimer, and joined the No. 75 (NZ) Squadron.[2] In 1942, Barnes was shot down over France, and spent three years in German prisoner-of-war camps. He put pressure on German resources helping fellow prisoners escape, and received various punishments, including a sentencing to be shot, though later the camp brutality eased, and Barnes was not executed.[2] In 1945, Barnes was appointed a Member of the Order of the British Empire (Military Division), for distinguished service while a prisoner-of-war.[3]
