Günther Prien and U-47 : the Bull of Scapa Flow

On the night of 13/14 October 1939, the Type VIIB U-boat U-47, on its second war patrol, penetrated the main Royal Navy base at Scapa Flow and sank the British battleship HMS Royal Oak. This legendary attack is remembered as one of the most audacious raids in the history of submarine warfare. Over the months that followed, U-47 went on to complete a total of ten war patrols. During these, Kapita nleutnant Gu nther Prien and his crew sank a total of 31 Allied ships and damaged eight more, making it one of the most successful U-boats of the Second World War. This book charts the full story of U-47, its commander and crew.
