The President of the United States in the name of the Congress takes pride in presenting the MEDAL OF HONOR posthumously to Ralph Ellis Dias Private First Class United States Marine Corps for service as set forth in the following CITATION: As a member of a reaction force which was pinned down by enemy fire while assisting a platoon in the same circumstance, PFC Dias, observing that both units were sustaining casualties, initiated an aggressive assault against an enemy machinegun bunker which was the principal source of hostile fire. Severely wounded by enemy snipers while charging across the open area, he pulled himself to the shelter of a nearby rock. Braving enemy fire for a second time, PFC Dias was again wounded. Unable to walk, he crawled 15 meters to the protection of a rock located near his objective and, repeatedly exposing himself to intense hostile fire, unsuccessfully threw several hand grenades at the machinegun emplacement. Still determined to destroy the emplacement, PFC Dias again moved into the open and was wounded a third time by sniper fire. As he threw a last grenade which destroyed the enemy position, he was mortally wounded by another enemy round. PFC Dias' indomitable courage, dynamic initiative, and selfless devotion to duty upheld the highest traditions of the Marine Corps and the U.S. Naval Service. He gallantly gave his life in the service to his country.
