German “Pocket Battleship” Lutzow, heavy cruiser Admiral Hipper and six destroyers descend on an important Arctic Convoy heading for the USSR. In the freezing waters of the Barents Sea, outgunned Royal Navy destroyers charge forward to defend their precious merchantmen from the superior German warships. The resulting battle will be a humiliation for the Kriegsmarine. Hitler will decide that his surface fleet is ineffective against the Royal Navy, and he will change his strategy in the Battle of the Atlantic overnight.
