In this special 4-part series, we look back at the life of Adolf Hitler. With the help of Frank McDonough, a leading historian of the Third Reich, we follow Hitler from childhood to adulthood and learn how an awkward, aspiring artist became one of history's most infamous dictators.

In this third episode, we pick up Hitler's story with the sweeping German military victories of 1939. Emboldened by these successes, Nazi Germany goes head-to-head with the Soviet Union. But the tide begins to turn as Hitler makes a series of strategic mistakes. His health deteriorates as the world closes in on the Third Reich. Finally, beneath the rubble of the German capital and surrounded by his enemies, Hitler's story comes to an end.
