John Moon was born in Macomb, Illinois, on April 3, 1916. He grew up on West Fisk Street with his parents, four brothers, and five sisters. In December 1941, when Pearl Harbor was attacked, after looking at his wife and son, he wrote, “How could I not enlist…making the world and my family safe from any more wars?” Consequently, he enlisted in the Marine Corps.
Moon served in the Marine Corps 5th Division which served in the Pacific Theater and saw major action during the battle of Iwo Jima. For thirteen days, Moon fought his way with his detachment to one of the three airports on the island before being shot in the leg. He and another injured soldier worked their way back down to the beaches where he was placed on a hospital ship.
At 100 years old, Moon is believed to be the oldest surviving Marine from the battle of Iwo Jima.
