After the cataclysmic fall of Stalingrad, Germany's campaign in Russia stood on a knife's edge. Hitler had to break Russia quickly or the war would be over. Thus 'Operation Citadel' was conceived. This was a plan to eliminate the huge salient around the Russian city of Kursk and trap the enormous Soviet Army in a noose of German steel. The only trouble was that the Russians knew it was coming... This is the story of that battle through the eyes of a remarkable group of people the men and women who fought it. All in all, two million soldiers, 6000 tanks and 4000 aircraft fought in the seven day offensive and after their defeat, the Germans never took another step forward into the motherland.
