December 7, 1941 was a Sunday. This day is best remembered for being the date of the Japanese attack on Pearl Harbor, the United States naval base in Honolulu, Hawaii. As a result of the attack, the U.S. entered World War II.
The attack on Pearl Harbor began at around 8 a.m. and lasted for 2 hours. When it ended, more than 2,000 American military members were dead and 1,000 more were wounded. About 200 airplanes and 20 naval ships were destroyed in the attack, including the USS Arizona. The day after the attack, the U.S. declared war on Japan. In retaliation, Italy and Germany, which were allies of Japan, declared war on the U.S.
