Hi Lee, yes I got you to have a look via your website which I came across before landing here - you didn't turn up anything. Not unusual I believe as most men were just desperate to get home and couldn't be bothered with filling in the forms - my great granddad had been behind the wire since June 1940 so I can hardly blame him! I had hoped that the Germans with their stereotypical Teutonic efficiency would have a file on him somewhere but as I said the National Archives said different. I am led to believe that the number of file cards is pretty large though and given the chaos at the end of the war it isn't difficult to imagine some cards being lost or filed in the wrong place but short of going through each box of cards there's no way to know for sure is there? At least if and when the ICRC do release the files they are likely to make them freely available rather than flogging them to the highest bidder - based on how they handled the WW1 records they have.
