During WWII, the Bismark was one of the most famous ships in Nazi Germany's Kriegsmarine.

So how exactly would the Allies manage to track her down and if they did what on earth would take her down...?

Presented by Dan Snow, this exclusive episode of History Hit's Bismark series takes us on a journey into the first stages of the hunt for the Bismark.
