When Hitler unleashed Operation Barbarossa against the Soviet Union in June 1941, the 23-tonne Panzer III was in the vanguard of the German assault. It saw widespread use during the Second World War in campaigns that included Poland, France, the Soviet Union, the Balkans, North Africa and Normandy. Centrepiece of the Haynes Panzer III Tank Manual is the Bovington Tank Museum's PzKpfw III Ausf L, which has been restored to running condition. Full coverage is given of the tank's design, construction, war service and the restoration of the Tank Museum's Ausf L version.
