Long story, try to keep it short. A relative was in both Torun and Marienburg and survived the Long March. I have all of his letters home from 1940 - 45. This triggered an interest in those camps and I have been collecting books and ephemera concerning those camps. I recently acquired a set of photos from WW2 stamped XXa showing the funeral at Malbork cemetery of a Gunner Thomas Crook RA. I have found some info on him online and have been able to create a basic family tree for him. What I am interested in is how he died in captivity and wondering if there are any resources for researching that?
