Lt. William Arthur Stanley Porter, 18th Bn., Can. Infy., Western Ontario Regt.
For conspicuous gallantry. He, while in command of a platoon on the right flank of his battalion, found the advance was delayed by an enemy machine-gun nest in a wood to the right of the front. He formed his platoon so as to overcome the garrison of the post, thus allowing the advance to proceed. His quick initiative saved many casualties and assisted the advance.
