Wilhelm Bender left for posterity some very interesting photo albums which he captioned with his own words. He started his military career as a medical soldier, later he took part in the defensive battles of Orel, Bryansk, Kovel and later participated in suppression of the Warsaw uprising and in defense of Danzig bridgehead with leichte Artillerie-Abteilung 849, which was equipped with Raupenschlepper Ost vehicles. This is a story of his military experiences told in more than 300 photos.
