During the attack on Le Quesnoy on the 4th November Rifleman Hallett, seeing his platoon held up by machine-gun fire, rushed forward and alone with his Lewis gun put the enemy gun out of action. Following this up he rushed the post with his revolver, and, killing one of the enemy, took the rest prisoner. His prompt action and dashing courage were of the highest order and saved many casualties.'
