On 7 December 1941 USS CALIFORNIA was moored at the southernmost berth of "Battleship Row" and was with other dreadnoughts of the Battle Force when the Japanese launched their aerial attack. As she was about to undergo a material inspection, watertight integrity was not at its maximum; consequently the ship suffered great damage when hit. At 0805 a bomb exploded below decks, setting off an antiaircraft ammunition magazine and killing about 50 men. A second bomb ruptured her bow plates. Despite valiant efforts to keep her afloat the inrushing water could not be isolated and CALIFORNIA settled into the mud with only her superstructure remaining above the surface. When the action ended, 98 of her crew were lost and 61 wounded.
