07 December 1941: Japan Attacks Pearl Harbor
On the morning of December 7, 1941, the United States was thrust into World War II when the Imperial Japanese Navy launched a devastating surprise attack on the American naval base at Pearl Harbor, Hawaii. In less than two hours, Japanese aircraft killed 2,403 Americans, wounded over 1,000 more, and destroyed or damaged 19 U.S. Navy ships and more than 300 aircraft. President Franklin D. Roosevelt would declare it a date which will live in infamy, and the attack fundamentally altered the course of the twentieth century.
The assault began at 7:48 a.m. Hawaiian time when the first wave of 183 Japanese aircraft descended upon the unsuspecting base. A second wave of 170 planes followed, targeting battleships, airfields, and other military installations. The Japanese strike force had launched from six aircraft carriers positioned about 230 miles north of Oahu, having traveled across the Pacific undetected. American forces, caught completely off guard on a quiet Sunday morning, struggled to mount an effective defense.
The destruction was catastrophic. The battleship USS Arizona exploded when a bomb ignited its forward ammunition magazines, killing 1,177 sailors and Marines in a single blast. The ship sank in minutes and remains on the harbor floor today as a memorial to those who perished. The USS Oklahoma capsized after being struck by multiple torpedoes, trapping hundreds of sailors inside. In total, eight battleships were damaged or destroyed, though all but the Arizona and Oklahoma were eventually raised and returned to service.
The following day, President Roosevelt addressed a joint session of Congress, delivering one of the most famous speeches in American history. Within an hour, Congress declared war on Japan with only one dissenting vote, cast by pacifist Representative Jeannette Rankin of Montana. Germany and Italy, allied with Japan, declared war on the United States three days later, and America found itself fully engaged in a global conflict on two fronts.
Pearl Harbor transformed the United States from an isolationist nation reluctant to enter foreign wars into the world preeminent military power. The attack united Americans across political and social divisions, generating an unprecedented mobilization of military and industrial resources. The war that followed would cost hundreds of thousands of American lives but would ultimately result in Allied victory and reshape the world order. Each December 7, Americans pause to remember those who died at Pearl Harbor and to reflect on the sacrifices made by the Greatest Generation in defense of freedom.
