Naval Station Pearl Harbor
The overall death toll was 2,467 people: 2,403 American citizens—2,335 members of the U.S. military and 68 civilians—and 64 members of the Imperial Japanese Navy. Five U.S. battleships were sunk and the other remaining three were badly damaged. Overall, nine ships of the U.S. fleet were sunk and 21 ships were severely damaged. Three of the 21 would be irreparable. 188 U.S. aircraft were completely destroyed and 159 others were damaged. Japan lost 29 out of the 353 aircraft they attacked with. The attack on Pearl Harbor was the largest destruction of life and property on American soil both in peacetime and in general by foreign nationals prior to the September 11 attacks, and remains the deadliest attack on American soil both in peacetime and in general by a foreign nation.
Solomon Islands campaign
On December 7, 1941, after failing to resolve a dispute with the United States over Japan's actions in China and French Indochina, the Japanese attacked the US Pacific fleet at Pearl Harbor, Hawaii. The attack crippled most of the U.S. Pacific Fleet's battleships and started a formal state of war between the two nations. Attacks on British Empire possessions in the Pacific, beginning with an attack on Hong Kong almost simultaneous with the Pearl Harbor attack, brought the United Kingdom, Australia and New Zealand into the conflict. In launching this war, Japanese leaders sought to neutralize the U.S. fleet, seize possessions rich in natural resources, and obtain strategic military bases to defend their far-flung empire. In the words of the Japanese Navy's Combined Fleet Secret Order Number One, dated November 1, 1941, the goals of the initial Japanese campaigns in the impending war were to, "(eject) British and American strength from the Netherlands Indies and the Philippines, (and) to establish a policy of autonomous self-sufficiency and economic independence."
