The President of the United States of America takes pleasure in presenting the Navy Cross to Private First Class Clinton M. Adcock (MCSN: 562230), United States Marine Corps, for extraordinary heroism and devotion to duty while serving as a Rifleman of Company I, Third Battalion, Twenty-Third Marines, FOURTH Marine Division, in action against enemy Japanese forces on Iwo Jima, Volcano Islands, 21 February 1945. When an enemy hand grenade landed in the foxhole he shared with two companions, Private First Class Adcock courageously attempted to shield the others in a gallant effort to dispose of the grenade. Although he suffered the loss of his right hand, right eye and was seriously wounded in the side after absorbing the full blast of the explosion he seized an automatic rifle in his left hand and succeeded in killing two of the Japanese as they attacked his position. His resolute fortitude and gallant spirit of self-sacrifice were in keeping with the highest traditions of the United States Naval Service.
