On the night of 31 March 1945 Lance-Sergeant Wallace, 11 Canadian Field Company, Royal Canadian Engineers, was detailed to reconnoitre the bridge at Etten, Holland which was reported demolished and would hold up the advance of the brigade. Information was required quickly to prepare for the bridging task. The tactical situation at that hour was obscure and Lance-Sergeant Wallace was given a covering party from the South Saskatchewan Regiment to assist. On moving up the party was under heavy mortar fire and at about 200 yards from the bridge site they were pinned down by small arms fire. The covering party said it was not advisable to advance further. Realizing the information was vital to operations this Non-Commissioned Officer crawled on his stomach right up to the bridge and got the necessary information. At first light on 12 April 1945 Lance-Sergeant Wallace went forward with his Platoon Commander to make a reconnaissance of a demolished bridge at Bielen, Holland. The whole brigade was held up at this time until the construction of the bridge was completed by engineers. The far bank was held by the enemy and enemy snipers were very active. Disregarding this they crawled forward to the bridge to obtain the necessary information, but in doing this the officer was severely wounded. By this time heavy small arms fire was raking the bridge. He then crawled back across open ground to the leading infantry to obtain aid for his wounded officer. In doing so he was seriously wounded in the head. This did not deter him and he crawled back to an infantry position where a party was organized to give covering fire while the officer was brought out. Not until this had been accomplished and his information on the bridge passed on to Company Headquarters did he allow himself to be evacuated to hospital. The courage and devotion to duty of this Non-Commissioned Officer in his capacity as Section Lance-Sergeant and Reconnaissance Lance-Sergeant in carrying out many hazardous tasks throughout the whole campaign is worthy of the highest praise. His perseverance and personal bravery is not only a fine example to the Corps of Royal Canadian Engineers but in all cases speeded up the advance of the brigade or division which otherwise would have been seriously delayed.
