Awful subject lost remains and families not knowing the resting place of their loved ones.
Last year I looked into getting a photo of the grave of a Luftwaffe FW 190 pilot that was shot down over South Devon. He was interred in a cemetery in Plymouth, and after the war exhumed for re-burial at Cannock German Cemetery. There are references in Plymouth as to his grave, which obviously doesn't exist any more. Cannock can't help as they don't think they ever received the casket. He wasn't a lone exhumation, if I remember correctly there were about a dozen other Germans exhumed at the same time. All are accounted for at Cannock.
How awful that we lost his remains and that his family cannot visit his grave.
