'For conspicuous gallantry and devotion to duty near Le Quesnoy on the 4th November 1918. During the attack on this date Corporal Mulvaney was in charge of a Lewis gun section. On coming to the railway line he encountered an enemy machine gun which was holding up the advance of the Company on his right. Ordering his No. 1 to engage the gun he himself worked round to a flank and alone rushed the post capturing the machine gun and four of the enemy. By his prompt action and disregard of danger he undoubtedly saved his Battalion a great many casualties. Throughout the action he led his section with dash and set a fine example to his men.'

'For conspicuous gallantry and devotion to duty on 8th October, 1918, near Crevecoeur. On reaching the final objective it was found that the enemy, about fifty strong, was holding a strongly wired fence with three machine guns. He was immediately singled out by an enemy machine gun, but with his second burst of fire he killed the Nos. 1 and 2; a moment later he disposed of a second machine gun in the same way.'
