In this riveting personal account, an authentic American hero relives the perils and triumphs of eight harrowing patrols aboard one of America's most successful World War II submarines. Courageous deeds and terror-filled moments - as well as the endless hard work of maintaining and operating a combat sub - are vividly recalled in James Calvert's candid portrait.

From rigorous training and shakedown cruises off the coast of New England, to tense patrols within shouting distance of Japan's major cities, the progress of the newly commissioned USS Jack parallels Calvert's own growth from callow ensign to charter member of one of the sharpest attack teams in the fleet.
