Herrera turned his prisoners over to men in his squad, then started crawling toward the other machine gun, firing as he went. ("My M-1 was talking, and the Germans understood what it was saying," he commented later.) The position was protected by a minefield; GIs were throwing rocks into the area in an effort to explode the mines. Herrera got up and charged the Germans anyway, but as he neared the machine-gun nest, he stepped on a mine. He was thrown to the ground, both of his feet blown off at the ankle. Though bleeding heavily, he lay on his stomach and fired at the Germans, forcing them to stay down and thus enabling his squad to skirt the minefield, flank the enemy, and move in for the kill.
