The Battle of Hood and Bismarck
It was the greatest sea battle of World War II. The Hood was built before the first world war, a modern British galleon designed to outrun and outgun any enemy. The Bismark was Germany's answer, a defensive naval masterpiece. The battle ended in the destruction of both warships and claimed the lives of almost 3,500 men. Now, scientists and historians are on a quest to resurrect them from the deep.
