The Panzer III was designed as part of Hitler's re-armarment program in the mid-1930's and played a key role in the German blitzkrieg offensives in Poland, France and the Soviet Union. Although it lacked adequate firepower and could not match more advanced Allied tanks like the T-34, it stayed in service in North Africa and on the Eastern Front and it was still encountered in action in Normandy towards the end of the war. Its reliable chassis was also adapted for assault gun production. In this form, as the Sturmgeschtz III, it took part in the defensive battles fought by the Wehrmacht as it retreated in Italy, France and eastern Europe.

Anthony Tucker-Jones's selection of photographs show the Panzer III in every theater of the war and at every stage, and his text gives an insight into the design history and fighting performance of this historic armored vehicle.
