Pearl Harbor is a harbor on the island of Oʻahu, Hawaiʻi, west of Honolulu. Much of the harbor and surrounding lands is a United States Navy deep-water naval base. It is also the headquarters of the U.S. Pacific Fleet. The attack on Pearl Harbor by the Empire of Japan on December 7, 1941, brought the United States into World War II.   Pearl Harbor was originally an extensive, shallow embayment called Wai Momi (meaning, “pearl water”) or Puʻuloa (meaning, “long hill”) by the Hawaiians. Puʻuloa was regarded as the home of the shark goddess, Kaʻahupahau, and her brother (or son), Kahiʻuka, in Hawaiian legends.

Making due allowance for legendary amplification of a known fact, the estuary doubtless had an outlet for its waters where the present gap is; but the legend is probably correct in giving Keaunui the credit of having widened it and deepened it, so as to admit the passage of canoes, and even larger vessels, in and out of the Pearl River estuary. The harbor was teeming with pearl-producing oysters until the late 1800s. Aircraft and midget submarines of the Imperial Japanese Navy began an attack on the U.S. The Americans had deciphered Japan’s code earlier and knew about a planned attack before it actually occurred. However, due to difficulty in deciphering intercepted messages, the Americans failed to discover Japan's target location before the attack occurred.[5] Under the command of Admiral Isoroku Yamamoto, the attack was devastating in loss of life and damage to the U.S. fleet. At 06:05 on December 7, the six Japanese carriers launched a first wave of 183 planes composed mainly of dive bombers, horizontal bombers and fighters. The Japanese hit American ships and military insta...
