A U.S. Marine who fought in some of the most deadly and infamous World War II and Korean War battles, including the battle at Iwo Jima in Japan and North Korea’s Chosin Reservoir, recently celebrated his 100th birthday at the Pacifica Senior Living Center in Vista, California, according to The San Diego Union-Tribune.

First Sgt. John Farritor, spent 30 years in Corps ― 20 on active duty and 10 in reserves, the Union-Tribune reported. He is one of the few surviving Marine veterans who in September 1942 marched 55 miles from Camp Elliott in San Diego to the newly opened Marine base near Oceanside, California.

Celebrating his birthday in his dress blue uniform, Farritor was joined by a group of Marines from Camp Pendelton, California, July 9. Friends, senior center residents and Marines listened to Farritor’s Marine Corps experiences in a slideshow presentation by friend and a local historian Linda Dudik.

Farritor sang along to his “Happy Birthday” song and said, according to the Union-Tribune: “I enjoyed the first 100 years. But I don’t know what I’ll do from here on out."
