Quick to press the advantage after 8 Japanese had been driven from a blockhouse on D-day, Pfc. Ruhl single-handedly attacked the group, killing 1 of the enemy with his bayonet and another by rifle fire in his determined attempt to annihilate the escaping troops.

Cool and undaunted as the fury of hostile resistance steadily increased throughout the night, he voluntarily left the shelter of his tank trap early in the morning of D-day plus 1 and moved out under a tremendous volume of mortar and machinegun fire to rescue a wounded marine Iying in an exposed position approximately 40 yards forward of the line. Half pulling and half carrying the wounded man, he removed him to a defiladed position, called for an assistant and a stretcher and, again running the gauntlet of hostile fire, carried the casualty to an aid station some 300 yards distant on the beach. Returning to his platoon, he continued his valiant efforts, volunteering to investigate and apparently abandoned Japanese gun emplacement 75 yards forward of the right flank during consolidation of the front lines, and subsequently occupying the position through the night to prevent the enemy from repossessing the valuable weapon. Pushing forward in the assault against the vast network of fortifications surrounding Mt. Suribachi the following morning, he crawled with his platoon guide to the top of a Japanese bunker to bring fire to bear on enemy troops located on the far side of the bunker. Suddenly a hostile grenade landed between the 2 marines. Instantly Pfc. Ruhl called a warning to his fellow marine and dived on the deadly missile, at-sorbing the full impact of the shattering explosion in his own body and protecting all within range from the danger of flying fragments although he might easily have dropped from his position on the edge of the bunker to the ground below. An indomitable fighter, Pfc. Ruhl rendered heroic service toward the defeat of a ruthless enemy, and his valor, initiative and unfaltering spirit of self-sacrifice in the face of almost certain death sustain and enhance the highest traditions of the U.S. Naval Service. He gallantly gave his life for his country.
