Sink the Bismarck! is a 1960 black-and-white CinemaScope British war film based on the 1959 book The Last Nine Days of the Bismarck by C. S. Forester.

However, it manages to inflict damage on the Bismarck's bow. Bismarck returns fire, destroying the Prince of Wales''' bridge. Eventually, Prince of Wales emits a smoke screen behind which to retreat. Bismarck and Prinz Eugen also retreat, but they are shadowed by the cruisers HMS Suffolk and HMS Norfolk using radar. Later, Prinz Eugen breaks away and heads toward the port of Brest, in occupied France, while Bismarck turns and fires at the British cruisers to provide cover as it escapes. The attack forces the cruisers to retreat. An air assault from the carrier damages Bismarck's fuel tanks, but the vessel is otherwise largely undamaged. Back at London's operations headquarters, Captain Shepard gambles that Admiral Gunther Lütjens, in command of Bismarck, is
