The Japanese assault on Pearl Harbor, Hawaii on the morning of December 7th, 1941 was drawn up to eliminate the U.S. Pacific Fleet's advantage in the Pacific, allowing free reign across the region. The attack was part of several navy-army actions by the Japanese in taking ground in the Philippines, Guam, Wake Island, Malaya, Singapore and Hong Kong. Over 350 aircraft were committed to the assault on Pearl as were six aircraft carriers. The attack was a complete surprise and prompted the American entry into the war - brining with it the vast industrial and military resources that the country had to offer and thus changing the course of the war.
The attack on Hawaii resulted in 2,403 killed and 1,178 wounded (68 civilians were also killed). 188 aircraft were destroyed, many whil on the ground. Four battleships were sunk (the most famous of these being USS Arizona) and eight were damaged where they berthed.
