The second event occurred on the other side of the world. On December 7, Japanese aircraft carriers launched 366 aircraft in a sneak attack on the U.S. Navy Pacific Fleet at Pearl Harbor, sinking or damaging eight battleships at their moorings, destroying or crippling eleven other warships, and killing 2,400 Americans. Simultaneous attacks were launched on Malaya, Hong Kong, and the Philippines. In solidarity with their Japanese ally, Hitler and Mussolini quickly declared war on the United States.
