Just before 8:00 a.m. on Dec. 7, 1941, the first of two waves of attacking aircraft swept over Pearl Harbor. Barely 15 minutes later the most powerful battleships of the mighty U.S. Pacific Fleet were either sunk or burning wrecks. The California was half submerged, with her keel lying in the harbor's mud. Nearby, the West Virginia had her port side torn open. Her twisted metal was burning, but for now she was still afloat. Two other ships, the Tennessee and the Maryland, were battered, but in better shape than their sisters. Beside them, the Oklahoma had been struck by a barrage of torpedoes and capsized. The U.S.S. Nevada was the only battleship to get underway that morning, but she was damaged and had run up onto the beach. The worst fate was suffered by the U.S.S. Arizona,which blew up and sank, taking over 1,000 of her crew with her.
