1943 – Germany and Russia clash near the Soviet city of Kursk, as each vies for control of the Eastern Front. The Germans are led by Field Marshal Erich von Manstein – an aristocratic master tactician. Facing him is the Red Army’s Marshal Zhukov – ruthless, opinionated and dangerous to know. Hitler is convinced new super-weapons like the Tiger tank will win the fight and insists von Manstein hold off his attack until more arrive. Zhukov exploits the delay and orders his men to dig for victory. They create an elaborate network of defences to grind the enemy down – or blow them up… The two armies finally meet in a titanic clash of tanks - the biggest tank battle of all time - which will change the course of the war.
