Among submariners in World War II, Dudley "Mush" Morton stood out as a warrior without peer. At the helm of the USS Wahoo he completely changed the way the sea war was fought in the Pacific. He would relentlessly attack the Japanese at every opportunity, going through his supply of torpedoes in record time on every patrol. In only nine months, he racked up an astounding list of achievements, including being the first American skipper to wipe out an entire enemy convoy single-handedly.

Here, for the first time, is the life and legend of a heroic, dynamic, and ultimately divisive submarine commander who fought the war on his own terms, and refused to do so any other way.
