Peter and Dan Snow describe battles that transformed the 20th century, here telling the story of one of the most epic battles of World War II. With cutting-edge graphics, Peter describes how the tactics of Hitler and Stalin resulted in tragedy on both sides. Whilst Soviet citizens held on for life in the shattered city, Hitler's army froze to death in the countryside.
They film inside the infamous tractor factory, where Dan recounts one of the vicious clashes that flared up in the battle. And on a training exercise, experts from the British Army teach them how snipers would have operated around the city.
