According to the Volksbund, Karl was born on April 22nd 1928 in Hohenwarth . He held the rank of Grenadier. The card states that he served as a Panzer-pioneer. It says that on May 5th 1945, Karl drowned near Tittmonning in the Salzach river. He would have been 17 years old. It also looks like he’s wearing a panzer uniform in the photo but I could be wrong. Definitely an interesting card. I’m not sure what specific unit he served with, or how exactly he ended up drowning. If anyone finds additional information on him, id be very appreciative of the info.
