'For conspicuous gallantry and devotion to duty. In the attack on POLGYON WOOD, east of HOOGE, on 20/21st September, Sgt. VALLANCE was in charge of a platoon employed as carrying party. He was untiring in his efforts to get material into the forward dumps and passed many times through intense enemy barrage. When bombarded heavily by the enemy in the assembly position, he walked about reassuring the men with utter disregard to his own safety. After completing his carrying work, he reorganised his platoon in the front line, ready to meet any counter attack.'
