Third and fourth terms of the presidency of Franklin D. Roosevelt
On the morning of December 7, 1941, the Japanese struck the U.S. naval base at Pearl Harbor with a surprise attack, knocking out the main American battleship fleet and killing 2,403 American servicemen and civilians. The great majority of scholars have rejected the conspiracy thesis that Roosevelt, or any other high government officials, knew in advance about the Japanese attack on Pearl Harbor. The Japanese had kept their secrets closely guarded, and while senior American officials were aware that war was imminent, they did not expect an attack on Pearl Harbor. Roosevelt had anticipated that the first attack would take place in the Dutch East Indies, Thailand, or the Philippines.
Pacific War series
Shortly before 3pm local time, the third wave arrives over Pearl Harbor. This time, the defences are on alert, putting up a dense anti-aircraft barrage which inflicts severe losses, the strike force losing a third of its aircraft. But the attackers cause heavy damage nonetheless, destroying No 1 dry-dock, the oil tank farms and the headquarters of the Pacific Fleet, killing the Commander-in-Chief Admiral Kimmel. In addition, a number of ships left intact after the earlier attacks are sunk or damaged, including all of the submarines still moored in the harbor. Fuchida, his aircraft badly damaged, barely makes it back to his carrier. 
The novel ends with Admiral Yamamoto grimly resolved to remain in Hawaiian waters until the battle is brought to a decisive conclusion and Admiral Halsey on board the USS "Enterprise", less than a day’s sail from Pearl Hearbor, mounting a search for the enemy fleet that he has vowed vengeance upon.
