On the day of the Pearl Harbor attack, several Japanese junior officers urged Imperial Admiral Nagumo to carry out a third strike in order to destroy as much of Pearl Harbor's fuel and torpedo storage, maintenance, and dry dock facilities as possible. Nagumo chose to retreat expecting retaliation and fully believing the Japanese had done enough damage to keep America out of the Pacific for at least six months. In retrospect, sparing the vital dockyards, maintenance shops, and oil depots meant the U.S. could respond relatively quickly to Japanese activities in the Pacific. The Japanese bombers also failed to do any damage to the U.S Naval Carriers, only the battleships moored at the harbor. Most of which would return to battle within the war. While the Japanese celebrated their victory, little did they know that their fate was already sealed.
