'Operations Messines - 7th to 12th June 1917, and operations opposite Warneton 14th to 19th June 1917. As Officer Commanding the 1st Otago Batt., Lieut-Colonel Charters has always displayed the highest qualities of organisation and Command. It was his Battalion which established the advanced line of assembly trenches opposite Messines preparatory to the attack. During the battle itself on the 7th June, he commanded his Battalion with conspicuous success and showed fine qualities of leadership. He personally went forward under heavy artillery barrage, to ensure connection with the Division on his left, and on the night of the 8th of June during the heavy counter-attack, at great personal risk made a most valuable reconnaissance without orders from any superior authority to satisfy himself and the Brigade that the troops on his left front were not retiring, but that a relief was taking place. This information was of the highest value as the situation at that moment was very obscure. During the whole of the battle Lieut-Colonel Charters moved about among his men inspiring them with confidence and setting a marvellous example of cheerfulness. During the later operations opposite Warneton he again led his Battalion forward with great gallantry and seized a line of posts in the final objective. He again personally reconnoitred the line and was present during its consolidation. Later during August after the capture of La Basse Ville Lieut-Colonel Charters personally supervised the scouting of the advanced line, his Battalion carrying out the work with the greatest success under heavy machine-gun and shell fire.'
