Born January 11, 1909 in Andersonville, Georgia. Joined the U. S. Marine Corps. Assigned to the 4th Marine Division.
Lt. Colonel Dyess was killed on February 2, 1944 by a burst of enemy machine gun fire while standing on the parapet of an anti-tank trench directing a group of infantry in a flanking attack against the last Japanese position in the northern part of Namur Island. In this final assault, LtCol Dyess posted himself between the opposing lines and, exposed to fire from heavy automatic weapons, led his troops in the advance. Wherever the attack was slowed by heavier enemy fire, he quickly appeared and placed himself at the head of his men and inspired them to push forward.
Medal of Honor Citation
"For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty as Commanding Officer of the First Battalion, Twenty-Fourth Marines, Reinforced, Fourth Marine Division, in action against enemy Japanese forces during the assault on Namur Island, Kwajalein Atoll, Marshall Islands, 1 February and 2, 1944. Undaunted by severe fire from automatic Japanese weapons, Lieutenant Colonel Dyess launched a powerful final attack on the second day of the assault, unhesitatingly posting himself between the opposing lines to point out objectives and avenues of approach and personally leading the advancing troops. Alert, and determined to quicken the pace of the offensive against increased enemy fire, he was constantly at the head of advance units, inspiring his men to push forward until the Japanese had been driven back to a small center of resistance and victory assured. While standing on the parapet of an antitank trench directing a group of infantry in a flanking attack against the last enemy position, Lieutenant Colonel Dyess was killed by a burst of enemy machine-gun fire. His daring and forceful leadership and his valiant fighting spirit in the face of terrific opposition were in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country."
