I have been recruited from the Great War Forum where I have found the level of knowledge to be amazing. So I'm here now with your starter for ten, and its a cracker! My boss is off-line for a while and is looking for information on a Joe Johnson of Leeds. His family story says that he became a pow but escaped so many times that he ended up in Sobibor Concentration Camp. That's all; no number, rank, date, service or unit, but I bet someone out there can narrow it down. Good Luck and thanks. Gordon.
