 Instantly placing his one remaining machine gun in action, he delivered a shattering fusillade and succeeded in silencing the nearest and most threatening emplacement before his weapon jammed and the enemy, reopening fire with knee mortars and grenades, pinned down his unit for the second time.Shrewdly gauging the tactical situation and evolving a daring plan of counterattack, Sergeant Cole, armed solely with a pistol and one grenade, coolly advanced alone to the hostile pillboxes.Hurling his one grenade at the enemy in sudden, swift attack, he quickly withdrew, returned to his own lines for additional grenades and again advanced, attacked, and withdrew.
