The history of one of the greatest acts of deception as Kriegsmarine raiders disguised as merchant ships wrecked havoc on Allied shipping and the Allied cruisers who finally destroyed them.

This highly-illustrated Duel title covers the deadly game of cat and mouse, fought by these surface vessels during World War II.
