'For most conspicuous bravery and devotion to duty in attack. Private Nicholas, who was one of a Lewis gun section, had orders to form a defensive flank to the right of the advance which was subsequently checked by heavy machine-gun and rifle fire from an enemy strong point. Whereupon, followed by the remainder of his section at an interval of about twenty-five yards, Private Nicholas rushed forward alone, shot the officer in command of the strong point, and overcame the remainder of the garrison of sixteen by means of bombs and bayonet, capturing four wounded prisoners and a machine gun. He captured this strong point practically singlehanded, and thereby saved many casualties. Subsequently, when the advance had reached its limit, Private Nicholas collected ammunition under heavy machine-gun and rifle fire. His exceptional valour and coolness throughout the operations afforded an inspiring example to all.'

'Operations on Welsh and Bon Avis Ridges - 28 September to 1 October 1918. For fearless leadership and contempt of danger during the operations - particularly on 29 September when after a successful advance, his Company's flank was in the air and position critical. By skilful handling and heroic example, he inspired his men and so enabled his half Platoon to break an enemy attack of superior numbers. The success of the operations was in a considerable measure, due to his great example and contempt of danger.'
