Tells the story of the largest armoured battle ever fought. It took place at Kursk, south of Moscow in 1943. It lasted seven weeks, resulting in 254,470 dead on the Russian side and 100,000 on the German side. Hitler was determined to launch this last great offensive on the Eastern Front which, in the event, he lost. The programme uses archive footage of the battle, specially-shot scenes of the terrain where the battle was fought and the testimony of many who fought there.
