While leading his platoon in the assault 1st Lt. Robb was severely wounded by machinegun fire, but rather than go to the rear for proper treatment he remained with his platoon until ordered to the dressing station by his commanding officer. Returning within 45 minutes, he remained on duty throughout the entire night, inspecting his lines and establishing outposts. Early the next morning he was again wounded, once again displaying his remarkable devotion to duty by remaining in command of his platoon. Later the same day a bursting shell added 2 more wounds, the same shell killing his commanding officer and 2 officers of his company. He then assumed command of the company and organized its position in the trenches. Displaying wonderful courage and tenacity at the critical times, he was the only officer of his battalion who advanced beyond the town, and by clearing machinegun and sniping posts contributed largely to the aid of his battalion in holding their objective. His example of bravery and fortitude and his eagerness to continue with his mission despite severe wounds set before the enlisted men of his command a most wonderful standard of morale and self-sacrifice.
