Citation
"This Airman has taken part in numerous sorties and has displayed much skill, great coolness and determination. On one occasion his aircraft was very badly damaged by enemy action. Later it became necessary to leave by parachute as the aircraft could no longer be flown. Although the bomber was down to a very low level, Flight Sergeant Dunmall ensured that his crew were all clear before he himself left the controls. His action was characteristic of this fine captain."
