Thanks to everyone for the very interesting replies.

I wonder if there were any casualties amongst the POWs who volunteered to clear the mines and bombs in the UK?

Interestingly, I just found a reference in the book about Bert Trautmann detailing his job working on bomb disposal in Liverpool, Manchester and the surrounding areas. It appears he volunteered to do this, and was still employed in this capacity in 1949.
