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, Kapitänleutnant Günther 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.

The Royal Oak was one of the mightiest battleships of the British Navy although, prior to the start of the Second World War, it had been scheduled for retirement. Nonetheless, when it was sent to the bottom of the sea on 14 October 1939 the shock was felt thoughout Britain. How could it be vulnerable to attack when it lay inside the great naval base of Skapa Flow, ringed by defences that were believed, by the Royal navy, to be impregnable? U-47, commanded by Gunther Prien, had found a way though the maze to the heart of the anchorage where the Royal Oak lay. Suddenly two torpedoes blew the mighty battleship apart and it capsized with the loss of over 800 men. In the mayhem that followed, Prien and his crew escaped unnoticed. Gunther Prien went on to become, until his death in May 1941, the leading U-boat commander and was awarded Germany's highest decoration, the Knight's Cross - with the Oakleaves being awarded posthumously. U-Boat Commander is Prien's own account of his early life, his training for U-boat command in the early years of Hitler's Third Reich up to the sinking of the Royal Oak.

An exceptional figure in the history of the German Navy, Wolfgang Luth was one of only seven men in the Wehrmacht to win Germany's highest combat decoration, the Knight's Cross with Oak Leaves, Swords, and Diamonds. At one time or another he operated in almost every theater of the undersea war, from Norway to the Indian Ocean, and became the second most successful German U-boat ace in World War II, sinking more than 220,000 tons of merchant shipping. A master in the art of military leadership, Luth was the youngest man to be appointed to the rank of captain and the youngest to become commandant of the German Naval Academy. Nevertheless, his accomplishments were overshadowed by those of other great aces, such as Prien, Kretschmer, and Topp. The publication of this book in hardcover in 1990 marked the first comprehensive study of Luth's life. Jordan Vause corrects the long neglect by providing an entertaining and authoritative biography that places the ace in the context of the war at sea. This new paperback edition includes corrections and additional information collected by the author over the past decade.

With dozens of historical documents and over 400 photographs, the author not only presents a comprehensive history of U-boat crews and the undersea war, but also shows how those with an interest in the U-boat war can find U-boat-related artifacts and how they can trace many to specific boats - and then research what those boats and crews accomplished.

On the night of 13/14 October 1939, the German commander of U-boat U-47, Günther Prien, steered past the sunken block ships and chains which inadequately protected the British naval base at Scapa Flow in the Orkney Islands. The U-Boat sank the old British World War I battleship HMS Royal Oak and then escaped into the North Sea. The loss of the Royal Oak was insignificant in naval terms though over 800 men perished with her, however this was a bitter blow to British moral.
