Adolf Hitler's leadership relied on an inner voice and absolute certainties rather than advice and political debate. His grandiosity and hatred led to war aims and atrocities that went far beyond any concrete German interest, and beyond what most Germans initially wanted. Yet this strange man was once loved by millions. With the help of testimony from those who lived through these times, film archive - including color home movies - and specially shot documentary footage, this film reveals how Hitler managed to lead the German people to war in 1939 and orchestrate the dramatic German victory over the French in 1940. This is the second episode in a three-part series written and produced by Laurence Rees, who won a BAFTA for his previous series Nazis: A Warning from History and a Grierson award for his Auschwitz: the Nazis and the 'Final Solution'.
