At a critical point in the action, when all the officers of his platoon had become casualties, Cpl. Allex took command of the platoon and led it forward until the advance was stopped by fire from a machine-gun nest. He then advanced alone for about 30 yards in the face of intense fire and attacked the nest. With his bayonet he killed five of the enemy, and when it was broken, used the butt of his rifle, capturing 15 prisoners.
