The one thing I wouldn't be ashamed of is drinking beer or chasing women especially if I had completed 30 Ops with distinctly unfriendly people trying to make sure that I didn't.
If you are his immediate next of kin, you should be able to secure his service record from RAF Innsworth (at a cost)and that should clarify any issues. People on this board will always help with the 'translation' thereof.
Herewith the citation for your Father's DFC (London Gazette date 9th July 1943): -
"In June 1943 this officer was the rear gunner of an aircraft detailed to attack a target at Le Creusot. During the flight his aircraft was engaged by an enemy fighter. Coolly and skilfully, Pilot Officer Pay instructed his Captain as to the neccasary evasive action and, at the same time, used his guns with effect. Three of his guns jammed but he succeeded in clearing them as the attacker closed in and, with a devastating burst of fire, caused the enemy aircraft to dive steeply towards the sea when it exploded on hitting the water. This officer, who has taken part in numerous sorties, has displayed great courage and fine fighting qualities and has won the confidence of all with whom he has flown. He has destroyed 3 enemy aircraft in combat"
I'm sure you'll agree Andy that it is a fine citation, and clearly reflects your Father's fine and upstanding qualities both as an Airman of the Royal Air Force and as an Air Gunner. You should be - indeed i am certain you are - extremely proud of him.
I'm afraid that i can find no trace of a Bar to his DFC in my files.
I hope all is well with our Celtic cousins over the Channel - here in Wales we're being drizzled on immensely this evening, and i've got to go out to work in it shortly!!
I hope the above adds a little to your files Andy, all the best,
"You can take the boy out of Wales,
But you cannot takes Wales out of the boy"
