"Pilot Officer Allison has throughout his operational career displayed great courage, skill and initiative. In August 1944 he was detailed for an attack against Stettin. Whilst approaching the target his aircraft was attacked by two Junkers 88s and severely damaged. The rear turret was rendered completely unserviceable and Pilot Officer Allison's turret could only be worked by hand. Despite this, with outstanding determination, this officer managed to fire a long burst into the enemy aircraft which caught fire and exploded. This officer's gallantry and presence of mind have always been of the highest order."
