As the site of the surprise attack that spurred America's entrance into World War II, Pearl Harbor is one of the most significant places in U.S. history. On the morning of Dec. 7, 1941, Japanese fighter planes destroyed or damaged more than a dozen ships (including eight battleships) and hundreds of aircraft in an effort to demolish the Pacific fleet. More than 2,400 American soldiers and civilians died. The majority of those who perished were aboard the USS Arizona, which remains where it sank beneath 40 feet of water. The following day, on President Franklin D. Roosevelt's request, the U.S. Congress declared war on Japan. Today, more than 1.7 million people visit the Pearl Harbor National Memorial each year to engage with the nation's history and pay their respects to the fallen.
