Publishers Description:

The book presents the detailed combat history of German Panzer-Abteilung 103 as part of the 3. Panzergrenadier-Division in Italy from September 1943 to August 1944 based on the almost unknown war diary of this unit. The Panzer-Abteilung 103 was fully equipped with Sturmgeschütz III assault guns. This is an impressive look at tactical-level events and command decisions, highlighting the German armored combat tactics in Italy. The book includes a number of original maps and excellent photos.
