Later that same day, his platoon was attacked and pinned down by a second enemy stronghold, protected by an extensive mine field. Ignoring the danger Herrera again single-handedly charged, seeking to draw fire away from his comrades. A mine exploded and shattered one leg below the knee. Staggering up on his good leg he stepped on a second, severing that leg below the knee. Still Herrera laid machine gun fire while kneeling, allowing members of his platoon to skirt the mine field and capture the enemy position.
