Attack on Pearl Harbor
The attack commenced at 7:48 a.m. Hawaiian Time (18:18 GMT). The base was attacked by 353 Imperial Japanese aircraft (including fighters, level and dive bombers, and torpedo bombers) in two waves, launched from six aircraft carriers. All eight U.S. Navy battleships were damaged, with four sunk. All but were later raised, and six were returned to service and went on to fight in the war. The Japanese also sank or damaged three cruisers, three destroyers, an anti-aircraft training ship, and one minelayer. 188 U.S. aircraft were destroyed; 2,403 Americans were killed and 1,178 others were wounded. Important base installations such as the power station, dry dock, shipyard, maintenance, and fuel and torpedo storage facilities, as well as the submarine piers and headquarters building (also home of the intelligence section), were not attacked. Japanese losses were light: 29 aircraft and five midget submarines lost, and 64 servicemen killed. One Japanese sailor, Kazuo Sakamaki, was captured.
Attack on Pearl Harbor
The Zero flown by Petty Officer Shigenori Nishikaichi of "Hiryu" was damaged in the attack on Wheeler, so he flew to the rescue point on Niihau. The aircraft was further damaged on landing. Nishikaichi was helped from the wreckage by one of the native Hawaiians, who, aware of the tension between the United States and Japan, took the pilot's maps and other documents. The island's residents had no telephones or radio and were completely unaware of the attack on Pearl Harbor. Nishikaichi enlisted the support of three Japanese-American residents in an attempt to recover the documents. During the ensuing struggles, Nishikaichi was killed and a Hawaiian civilian was wounded; one collaborator committed suicide, and his wife and the third collaborator were sent to prison.
