Welcome to the new, updated and revamped, the first web site to be dedicated to the history of the WWII German Type VIIB submarine U-47 and its legendary commander, Knight's Cross holder Korvettenkapitän Günther Prien, the man behind the sinking of the prize British battleship Royal Oak.

"...the decision was a very, very difficult one. Never before had I been so impressed by the strength of the enemy as I was by those tanks rolling by; but I knew it absolutely had to be and I decided to strike out into the enemy."

Michael Wittmann, 13th June 1944
