In Commemoration of the Attack on Pearl Harbor

From Wikipedia:

The attack on Pearl Harbor was a surprise military strike conducted by the Japanese Navy against the United States naval base at Pearl Harbor, Hawaii, on the morning of December 7, 1941 (December 8 in Japan).

The base was attacked by 353 Japanese fighters, bombers and torpedo planes in two waves, launched from six aircraft carriers. All eight U.S. Navy battleships were damaged, with four being sunk. All but two of the eight were raised, repaired and returned to service later in the war. The Japanese also sank or damaged three cruisers, three destroyers, an anti-aircraft training ship, and one minelayer. One hundred eighty-eight U.S. aircraft were destroyed; 2,402 Americans were killed and 1,282 wounded. The power station, 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.

The attack came as a shock to the American people and led directly to the American entry into World War II in both the Pacific and European theaters. The following day (December 8) the United States declared war on Japan. Subsequent operations by the U.S. prompted Germany and Italy to declare war on the U.S. on December 11, which was reciprocated by the U.S. the same day.

.... President Franklin D. Roosevelt proclaimed December 7, 1941, "a date which will live in infamy".
