'For conspicuous gallantry and devotion to duty near Le Quesnoy on the 4th November 1918. During the attack on Le Quesnoy the enemy threatened to enfilade the whole of the attacking Company from a machine gun post sited on the railway line and for some time had the attackers pinned to the ground. Sergeant Ferguson at once led a small party to outflank the post and in spite of heavy machine gun fire he succeeded in silencing the post. He then returned and led forward the main attack reaching the objective and taking two machine guns and a number of prisoners.'
