On 12 June 1943, Morison and 23 or 25 others escaped from the camp during a delousing break. Twenty-two prisoners left the camp with two "guards", actually two fellow POWs in bogus German uniforms. Once outside, the group split up. The others were quickly recaptured, but he and Flight Lieutenant Lorne Welch, wearing fake uniforms, walked to a nearby airfield and attempted to steal an aircraft, a Junkers W 34. They had to abandon the attempt when the rightful crew appeared to fly away the aircraft. The next day, they returned and tried to steal a biplane, but were caught and eventually sent to Oflag IV-C at Colditz.
