I don't see anything in the London Gazette for Diane's father which is strange 
The Gazette is really poor to navigate...I did a search on a RAMC doctor yesterday whom I know won the MC at Arnhem....I have handled the actual MC and he was the family GP....But trace of it I could find none
Perhaps the Army Lists of the time would be a better idea...Fort George cannot have lost them as well!!!
(Methinks it was a bad day for them, and they didn't want to dig)
