Gunther Prien was one of the outstanding U Boat aces of the early part of WW2 and the first to win the coveted “Knight’s Cross”. His submarine U47 sank over 200,000 tons of Allied Shipping including the British battleship, “HMS Royal Oak” at anchor in Scapa Flow, Britain’s northern fleet anchorage.
Prien and U47 went missing on March 7, 1941 and no official record states how or why he and his U boat were lost. No trace of him or his boat has ever been found!
