Pearl Harbor has a significant place in U.S. history.

On December 7, 1941 Japanese war planes attacked Oahu. Included in the attacks were Kaneohe Naval Air Station, Pearl Harbor including Ford Island, Wheeler field, Hickam Field and Barber's Point.

The casualty list includes 2,335 servicemen and 68 civilians killed, with 1,178 wounded. Included are 1,104 men aboard the Battleship USS Arizona killed after a 1,760-pound air bomb penetrated into the forward magazine causing catastrophic explosions.

This link has a lot of information about the attack.
