Having overcome 2 machinegun nests under his skillful leadership, Sgt. Hall's platoon was stopped 800 yards from its final objective by machinegun fire of particular intensity. Ordering his men to take cover in a sunken road, he advanced alone on the enemy machinegun post and killed 5 members of the crew with his bayonet and thereby made possible the further advance of the line. While attacking another machinegun nest later in the day this gallant soldier was mortally wounded.
