In KZ Sachsenhausen, Yakov Dzhugashvili refuses Andrei Vlasov's offer to exchange him for Friedrich Paulus. Meanwhile, in Kursk, the Germans advance. Maximov flees, but finally turns back and chooses to be shot when captured.
When hearing about the German proposal regarding Yakov, Stalin rejects it, saying he will not trade a Field Marshal for a soldier. The Yugoslav partisans break out of an encirclement. The Soviet counter-offensive is launched in Kursk. Erich von Manstein commits all his forces to a final assault, bringing the Soviets close to defeat.
