Sample text

As commander in chief he could not risk so weakening the British Home Fleet as to give the Germans complete superiority in fast, heavy ships. He must preserve the King George V at any cost. The future demanded it. Reluctantly and no doubt with heavy heart he radioed the Admiralty in London and Vice-Admiral Somerville on the Renown. He told them that unless the Bismarck was slowed up considerably by midnight the King George V would then break o the chase and return to home base to refuel. The Rodney would continue the pursuit until daylight.

M. the Sheffield left Force H and made at high speed toward the German battleship. , did not notice the cruiser slipping away. Somerville radioed the carrier of this action, and the coded message was received. But it was not immediately deciphered. The cipher sta on the Ark Royal was too busy at the moment decoding a stream of radio messages from the carrier’s own planes shadowing the Bismarck. In the meantime the Sword sh, ying blind through cloud and mist, had spotted a ship on their radars in the approximate position of the Bismarck.

The chase seemed to be at an end. The spirits of the British aboard the two ships were about as black as the night which had now descended over the wind-swept seas. Then over the radio came a message which at rst merely seemed to confuse the situation. Admiral Tovey could make nothing of it. It was a signal from the Sheffield announcing that the Bismarck had reversed course. Instead of steering southeast for Brest she was now veering in the opposite direction! To the dispirited Sir John it made no sense.
