On February 19, Sergeant Cole led his machine gun section ashore in the D-Day assault of Iwo Jima. Moving forward with the initial assault wave, a hail of fire from two enemy emplacements halted his section's advance. Sergeant Cole personally destroyed them with hand grenades. His unit continued to advance until pinned down for a second time by enemy fire from three Japanese gun emplacements. One of these emplacements was destroyed by a machine-gunner in Cole's squad. When his machine guns jammed, armed only with a pistol and one hand grenade, Sergeant Cole made a one-man attack against the two remaining gun emplacements. Twice he returned to his own lines for additional grenades and continued the attack under fierce enemy fire until he had succeeded in destroying the enemy strong points.
