"Flight Sergeant Greenwell has displayed outstanding keenness for air operations and has participated in very many sorties. On one occasion, whilst over the Brest peninsular, his aircraft was extensively damaged when hit by anti-aircraft fire. In spite of this and in the face of adverse weather, Flight Sergeant Greenwell navigated the aircraft to an airfield. On another occasion the aircraft in which he was a member was badly hit and caught fire. The crew were forced to leave by parachute. Flight Sergeant Greenwell descended safely and lost no time in re-joining his squadron. This airman has invariably displayed a high standard of courage and devotion to duty."
