On this date, December 7, 1941, we pause to remember Pearl Harbor — a day that forever changed our nation. We honor the brave service members who stood in the face of unimaginable adversity and those who made the ultimate sacrifice. Their courage, resilience, and unwavering dedication to our country will never be forgotten. Today, we reflect, we remember, and we reaffirm our commitment to preserving the legacy of all who served.

The Day That Lives in Infamy

84 years ago, the devastating surprise attack on Naval Base Pearl Harbor by the Imperial Japanese Navy claimed the lives of 2,403 American service members, wounded 1,178, and resulted in significant damage or loss of 8 battleships, 3 cruisers, and more than 180 aircraft. On this fateful day in 1941, 353 aircraft descended upon the base, unleashing destruction in under 90 minutes. Despite the unpreparedness, courageous Marines and U.S. Navy Sailors mounted a defense, engaging the enemy with anti-aircraft fire and mounting rescue efforts.

A key factor in America's eventual recovery was the fortunate absence of all U.S. aircraft carriers from Pearl Harbor during the assault. The attack served as a pivotal event, compelling the United States to formally enter World War II. Just six months later, the U.S. would secure a crucial victory at the Battle of Midway, where the newly created 3rd and 6th Marine Defense Battalions played a crucial role in defending the island and stopping the Japanese advance across the Pacific.
