William Kimber, 1st.Eng.ed., 1954. 200 + 8 (advt.) pp., frontis., + 8 other photo-plates & a map of Scapa Flow. D.j., 22 x 14cm. V.G.+. This story of Lt. Gunther Prien was first published in Germany in 1942, and it describes his daring exploit in 1939 when in U.47 he penetrated British defences at Scapa Flow and torpedoed and sank the battleship HMS ROYAL OAK. The author also recalls Prien’s early days, his station off the Shetlands preying on merchant ships, U.47’s failure at Narvik, and his sinking of the Blue Star liner ARANDORA STAR in 1940. In 1941 Prien disappeared, believed killed in action, but in post-war Germany, rumours circulated that Prien had mutinied, been sent to a concentration camp, and executed. This account was published in Germany in 1949 in a booklet entitled What Really Happened to Prien ? However, the Admiralty produced records to confirm that Prien had fallen victim to the Royal Navy. On the 8th March 1941 Lt.Cmdr. J. M. Rowland, DSC, carried out a successful pursuit and attack on U.47 in HMS WOLVERINE. There were no survivors from the U-boat.
