Completed in 1940, the Bismarck was widely regarded as the most powerful warship in the world. In April 1941, Admiral Tovey of the British Royal Navy detected an attempt by the Bismarck to break out into the Atlantic and the hunt was on. In a first battle, the Bismarck sank HMS Hood. But Tovey used radar to track her down again and finally she was surrounded by British heavy warships and pounded into submission.
