PBS Secrets of the Dead - Deadliest Battle (2010)

Germany's invasion of the Soviet Union in 1941 was the largest troop offensive in military history. And the Battle of Stalingrad is arguably the deadliest single battle the world has ever seen.
The eventual Russian victory has long been lauded as a shining example of Stalin's military genius. He is said to have baited the much more powerful and technologically advanced German army with a carefully executed withdrawal, then caught the Nazis unprepared in vicious city-block-by-city-block fighting that decimated the German forces. By the time the battle was over, more than one million lives had been lost and the course of the war permanently altered. But 70 years after the battle was fought, newly-released archives from behind the Iron Curtain are allowing a more detailed analysis of the fighting, and revealing a very different picture of the battle that changed the course of history.
The documents, combined with rare archival footage, detailed eye-witness accounts from survivors on both sides, and commentary from Sergei Khrushchev, whose father Nikita served on Stalin's Military Council before becoming leader of the Soviet union himself, reveal a tale of complicated campaigns, titanic clash between the armies of two egotistical leaders who refused to back down, and poor decisions that cost hundreds of thousands of lives.
