Ralph Henry Johnson

He shielded his patrol from a grenade and held the perimeter

Ralph Henry Johnson was born on 11 January 1949 in Charleston, South Carolina. He attended school in Charleston before enlisting in the Marine Corps Reserve in March 1967 and transferring to the regular Marine Corps that July. After recruit and infantry training in California, he arrived in Vietnam in January 1968. He served as a private first class and reconnaissance scout with Company A, 1st Reconnaissance Battalion, 1st Marine Division.

On 5 March 1968 during Operation Rock in Vietnam, Johnson's patrol held an observation post on Hill 146 overlooking the Quan Duc Valley. During an enemy assault, a grenade landed in his fighting hole. He warned his two companions and covered the grenade with his body. He died in the explosion, saving one Marine and helping prevent a breach of the patrol's perimeter.

Vice President Spiro Agnew presented Johnson's posthumous Medal of Honor to his family on 20 April 1970. He is buried in Beaufort National Cemetery. In May 2026 the International African American Museum in Charleston unveiled an attributed display of his medals and the flag presented to his family.

Medal of Honor citation

For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as a reconnaissance scout with Company A, in action against the North Vietnamese Army and Viet Cong forces. In the early morning hours during Operation Rock, Pfc. Johnson was a member of a 15-man reconnaissance patrol manning an observation post on Hill 146 overlooking the Quan Duc Valley deep in enemy-controlled territory. They were attacked by a platoon-size hostile force employing automatic weapons, satchel charges, and hand grenades. Suddenly, a hand grenade landed in the three-man fighting hole occupied by Pfc. Johnson and two fellow marines. Realizing the inherent danger to his two comrades, he shouted a warning and unhesitatingly hurled himself on the explosive device. When the grenade exploded, Pfc. Johnson absorbed the tremendous impact of the blast and was killed instantly. His prompt and heroic act saved the life of one marine at the cost of his life and undoubtedly prevented the enemy from penetrating his sector of the patrol's perimeter. Pfc. Johnson's courage, inspiring valor, and selfless devotion to duty were in keeping with the highest traditions of the Marine Corps and the U.S. Naval Service. He gallantly gave his life for his country.
