In late 1943, sPzAbt 503 was made part of Panzer Regiment Bake , a special battle group which fought in several fierce engagements in the Dnieper sector near Cherkassy. The sPzAbt 503 remained assigned to PzRgt. Bake until April 1944, then was withdrawn and sent to the West for refitting. After the success of two previous volumes devoted to these heavy tanks, this history of the Panzer-Abteilung s.SS 103/503 units is illustrated with 450 photographs, maps and various documents, as well as 20 colour profiles.
