On a quiet morning 79 years ago today, Imperial Japanese forces attacked the United States at Pearl Harbor, Hawaii. More than 2,400 Americans were killed and 1,100 more wounded. Twenty-one ships of the Pacific Fleet were sunk or damaged, including the USS Arizona. Shocked and angered by the attack, the country joined the Allied forces to fight World War II, inspired by the call of “Remember Pearl Harbor.” A moving reminder of the service and sacrifice of those who fought, the USS Arizona Memorial is jointly administered by the U.S. Navy and the National Park Service.
