On February 1, 1944, the day preceding Dyess's death, six U.S. Marine snipers were on patrol on Namur Island where Japanese forces had taken up protected positions following the Battle of Kwajalein. The Marine patrol had inadvertently moved behind enemy lines, surrounded on three sides by Japanese forces, where they came under small arms fire from a concealed position. One of the Marines was killed instantly, and four of the remaining five Marines sustained injuries from the attack. One of the injured Marines, Cpl. Frank Pokrop, later recalled, “with no protection and heavy fire coming at us from a few feet away and dusk approaching, we were certain to be killed. All of a sudden Col. Dyess broke through on the right, braving the very heavy fire, and got all of us out of there."
