"One night in September, 1944, this officer was captain and pilot in an aircraft detailed for a supply dropping mission in Holland. Before reaching the target the aircraft came under continuous light anti-aircraft fire for some ten minutes and was hit in several places. One engine was affected but Flying Officer Turnbull continued his flight to the target over which he made two runs to ensure that his supplies would be dropped in the proper area. On the return flight the aircraft was again hit and the defective engine caught fire. The propeller had to be feathered. Despite the loss of engine power, Flying Officer Turnbull flew the damaged aircraft to base. On this his first sortie as a captain he displayed skill, courage and devotion to duty of a high standard."
