The Golden Horseshoe: The Wartime Career of Otto Kretschmer, U-Boat Ace

The legendary U-boat ace Otto Kretschmer was branded "the Wolf of the Atlantic," for his exploits as one of the Kriegsmarine's finest U-boat commanders. In his dramatic wartime career he sank ship after ship, sowing terror among Allied convoys and dismay in those charged with their protection. Kretschmer was a daring officer who favored bringing his U-boat into the heart of the convoy and destroying it from within.

Robertson draws upon first-hand accounts of the deadly game at sea to paint a masterly portrait of life in the U-boats and weaves in the fascinating story of Kretschmer's exploits. Kretschmer was eventually captured and became a prisoner of war in March 1941, spending the rest of the war in a POW camp in Canada, before his release in 1947.
