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.
Puerto Ricans in World War II
There weren't any Puerto Rican military related fatalities when the Imperial Japanese Navy Air Service attacked Pearl Harbor. However, there was one civilian Puerto Rican fatality. Daniel LaVerne was a Puerto Rican amateur boxer who was working at Pearl Harbor's Red Hill underground fuel tank construction project when the Japanese attacked Pearl Harbor. He died as a result of the injuries which he received during the attack. His name is listed among the 2,338 Americans killed or mortally wounded on December 7, 1941, in the Remembrance Exhibit in the back lawn of the USS Arizona Memorial Visitor Center at Pearl Harbor.
