                  convoy OB318, U-110 commanded by Julius Lemp suffers serious

                  allowing the British destroyer HMS Bulldog to put across a
                  boarding party and seize an enigma machine and other vital

                  American vessels, the US merchant ship Robin Moor is sunk by
                  U-69 (Kptlt. Metzler). This sinking of a neutral American vessel
                  is publicly denounced by President Roosevelt and becomes yet
                  another argument for him in his secret desire for bringing
                  the United States into war against Germany. An RAF reconnaissance
                  plane sight the Bismarck and Prinz Eugen in the port of Bergen,

                  Bismarck is relentlessly bombarded by dozens of British warships,
                  including the battleships Rodney and King George V. After all
                  her guns are silenced, she is sunk by torpedo's from the cruiser
                  Dorsetshire. There are only 110 survivors out of a crew of
