In 1941, Nazi Germany, seemingly near invincible in its military might despite its failure to break the UK in the Battle of Britain, makes one of its most disastrous military moves. Despite the danger of a two front war and the existence of a non-aggression pact, Hitler orders the full scale invasion of the Soviet Union. This series explores the reasons for this undertaking, its vicious nature on both sides and the general series of events of the bloodiest theater of the war that would ultimately turn the tide in the fight against the Third Reich.
