The Coast Guard recognized three survivors of the Japanese attack on Pearl Harbor in a ceremony Friday on Coast Guard Island in Alameda, Calif.
The men received a standing ovation in recognition of their heroic actions during the Dec. 7, 1941 surprise attack.
One of the survivors, Ray Emory, 91, has made it his mission to ensure graves are properly identified at the National Memorial Cemetery of the Pacific, which fills the Punchbowl crater in Honolulu.
Using detective-like skills and personnel records, Emory, has aided in the identification of nine service members who died that fateful Sunday morning.
"I sleep at night," Emory told CNN. "It's very satisfying."
