Submarines were responsible for about 55 percent of the tonnage of the Japanese fleets sunk during World War II. The 22 percent casualty rate of U.S. submariners was the highest of the military services. This volume traces the career of the submarine the USS Puffer from the laying of her keel and her commissioning on April 27, 1943, until her departure for the scrap yard in late 1960. Compiled from interviews with former crew members, including the author's father, Donald B. McDonald, as well as other contemporary sources, it follows the crew of the Puffer through nine war patrols. Events recollected include the First War Patrol, which resulted in a record-setting 38 hour submergence because of enemy fire; the dangerous transfer of torpedoes while surfaced in enemy waters; and the wild bombardment of Japanese shore installations with the 5-inch deck gun. There are numerous wartime photographs and appendices providing a list of awards earned by the crew and a summary of claimed successful attacks. Brief biographies of the seven commissioned officers are also included.
