During the early morning hours of Dec. 7, 1941, fighter planes from Japan sneaked up on the American soldiers stationed there and launched a surprise attack. The Japanese had been planning this for months, and they managed to travel almost 500 miles to reach Pearl Harbor completely undetected. The attack was devastating, causing the deaths of more than 2,400 members of the American armed forces and injuring even more. The attack was a turning point in history and pushed the United States into World War II.
