his team, under terrific fire of enemy artillery, machineguns, and trench
mortars, he continued after all his comrades had become casualties and
he himself had been seriously wounded. He operated his rifle until he collapsed.
His act resulted in the capture of about 100 prisoners and several machineguns.
He succumbed from the effects of his wounds shortly after the accomplishment
of his heroic deed.
