Season 4

The Nazi empire ran on trains, from the personal trains of the leadership to the locomotives and service depots that serviced the network.

Railways were key to the planning and implementation of the Final Solution, used to bring victims to the death camps from all over Europe.

The fortifications the Nazis built in northern Italy were meant to slow the Allied advance. Now the team reconstructs their extent and depth.

After invading Norway in the spring of 1940, Nazi armed forces proceeded to fortify the entire country for war against Britain and the Soviet Union.

The war was lost long before it ended, but the Nazi propaganda apparatus was designed to keep that truth from its subjects for as long as possible.

The German air force was the most powerful and largest in Europe at the beginning of World War II, and it played a key part in Hitler's conquests.
