The Royal Navy's week long chase of the formidable German battleship Bismarck culminated in the foul evening weather of 26th May 1941. Despite the deck of HMS Ark Royal pitching through 55 feet, S/Lt John Moffat was one of fifteen Swordfish pilots who took off to attack Bismarck. After 90 minutes of arduous and turbulent flying the Swordfish found their quarry and dived through the intense anti-aircraft fire to drop their torpedoes. One of these hit and jammed Bismarck's rudder and condemned the battleship to sail in slow circles.
The Royal Navy's own capital ships then closed in and pounded Bismarck into a burning wreck.
