A somber ceremony was held Saturday at the Pearl Harbor Visitors Center to mark the 78th anniversary of the surprise Japanese attack on the Hawaii naval base.

The event was attended by more than 2,000 people, including about a dozen men in their 90s who survived the Dec. 7, 1941, attack that led to the entry of the U.S. into World War II.

“It makes you think of all the servicemen who have passed ahead of me,” said Herb Elfring, 97, of Jackson, Mich. He’s the last of his old regiment who is still alive.

Elfring was in the Army, assigned to the 251st Coast Artillery, part of the California National Guard. The unit’s job was to protect airfields, but they weren’t expecting an attack that morning.

Elfring was standing at the edge of his barracks at Camp Malakole a few miles down the coast from Pearl Harbor, reading a bulletin board when Japanese Zero planes flew over.

“I could hear it coming but didn’t pay attention to it until the strafing bullets were hitting the pavement about 15 feet away from me,” he said.

The ceremony featured a moment of silence at 7:55 a.m. -- the same minute of the beginning of the attack.

The silence was broken by a flyover of U.S. Air Force fighter jets in missing man formation.

More than 2,300 members of the U.S. military were killed in the attack. Nearly half -- or 1,177 -- were Marines and sailors serving on the USS Arizona, a battleship moored in the harbor. The vessel sank within 9 minutes of being hit, taking most of its crew down with it. Read more at FOX News
