Tokyo Torpedo: The U-Boat Series (The U-Boat Book #3)
During the terrible Battle of the Atlantic, Hitler’s U-Boats had become the scourge of the ocean. Of all of his U-Boat aces, none as more brilliant or more feared than Kapitanleutnant Konrad Bergman.
But while Bergman had been prowling the Atlantic convoy routes, another deadly conflict was raging under burning Eastern skies. When word came that Japan and invented a weapon that could swing the pendulum of the war for Germany, it was Bergman who was sent to slip through the American net and wrest the secret of the Tokyo Torpedo from Japan—single-handed!
