The legendary U-boat ace Otto Kretschmer was branded 'the wolf of the Atlantic' & for good reason. In his dramatic wartime career he sank ship after ship sowing terror among Allied convoys & dismay in those charged with their protection. Kretschmer was a daring officer who favoured bringing his U-boat into the heart of the convoy & destroying it from within. He earned himself a tremendous reputation before his capture in March 1941 & The Golden Horseshoe makes it clear why. Terence Robertson's biography of the U-boat ace draws upon first-hand experience of conditions & the deadly game as the hunter sought to outfox the hunted. He paints a masterly portrait of life at sea & weaves in the fascinating story of Kretschmer & the exploits of his U-Boats. Kretschmer was eventually captured & interviewed by Captain Mc Intyre of HMS Walker an episode which is also recounted in this book. Otto Kretschmer became a prisoner of war in March 1941 & spent most of the rest of the war in Bowmanville camp Canada before his release in 1947.
