U99 was one of the most famous U-boats of the Second World War. The
commander, Otto Kretschmer, accounted for the greatest total tons of
shipping sunk during WW2 and hence earned himself a Knights Cross with
Oakleaves and Crossed Swords as well as the nickname of Tonnage King.
During the night of 16/17 March 1941 whilst
undertaking its eighth war patrol U-99 was sunk by a depth charge attack
by the British Destroyer HMS Walker.
