During World War II, the Kriegsmarine armed a number of merchant vessels with concealed guns and torpedo tubes for surprise attacks against Allied shipping. To counter this deadly threat, the Royal Navy employed cruisers and their intelligence-gathering apparatus to find and destroy the disguised German commerce raiders. This Duel title covers the deadly game of cat and mouse, fought by these surface vessels during World War II.
