On 23 May 1944 it became apparent that 5 Canadian Armoured Division would pass through 1 Canadian Division somewhere along Trey route to exploit beyond the Adolph Hitler Line. It was essential that a reconnaissance be made of the Rio San Martino which was an obstacle on the immediate divisional front. Lieutenant Maund was briefed at 1, 600 hours and despatched to follow up the attack of the West Nova Scotia Regiment and obtain all necessary information. He proceeded up Trey route to within 1500 yards of his objective when shelling and mortaring forced him to leave his vehicle and proceed on foot.
En route he was twice knocked down by blast from shelling and passed through three mortar concentrations, but without hesitation or regard for his own safety, proceeded on to his objective. On reaching the objective he was pinned by two machine gun posts 150 yards away, on the forward slopes of Rio San Martino. He lay there for approximately three and one-half hours under observed enemy shelling, mortar fire and sniping, making the necessary observations and obtaining all the information required by the Commander, Royal Canadian Engineers. Then, only by crawling was he able to get back to West Nova Scotia Regimental Headquarters, a distance of 500 yards, where he reported the enemy positions. He then returned to Headquarters, Royal Canadian Engineers at 2000 hours and submitted such a complete report that on the information which it contained, it was established that tank crossing was not practical at the point which had previously been decided upon by the study of air photos.
Lieutenant Maund demonstrated throughout the highest standard of initiative, bravery and devotion to duty. Fully cognizant of the value of the information which he had been detailed to obtain, he ignored all risks in his determination to complete his task to the last detail.
