@LukeAyton I have a picture of the postcard notifying family of his liberation too. Dated 5 May 1945, three days before VE day. I don't know how long he'd been marching before he was picked up and sent it though.
@LukeAyton Odd coincidence: I was reading this tonight and it prompted me to look through everything I have about him. He was shot down this evening, exactly 78 years ago.
