Only in one small trench on the extreme left could it be turned back into the enemy lines, and, in order to effect that desirable operation, the whole had to flow right along the British front line first. The utter collapse, and consequent evacuation, of long stretches of the line considerably altered the method of holding it. Many of the posts were completely cut off from one another, except by movement across the open. Such movement was extremely hazardous by day, for the enemy snipers and machine gunners were only too ready to take advantage of the many opportunities which the new state of affairs gave them. With parapets sliding in and trenches filling, it was soon impossible for a man to move about in daylight without exposing himself. By night there was an additional danger. It required a man, with a very good sense of direction, to move over that area of water-logged and derelict trenches without losing his way. The case of Pte. T. Atkinson--the first prisoner the enemy secured from the Battalion--was a good illustration of this. In company with another man, he had successfully delivered rations to an isolated front line post, but, on the way back, the two disagreed about the direction of their own lines and separated, each going his own way. The other man rejoined his platoon in safety; Pte. Atkinson, apparently, walked straight across No Man’s Land into the arms of the enemy. The greatest hardships were suffered by men who were wounded in the front line. If a man had the misfortune to be hit early in the day he could seldom be got away until after dark; often in great pain, and always under the most miserable conditions, he would have to wait for many hours before he could receive proper attention. Even when dusk came his lot was a most unenviable one. The journey to the Canal Bank often took two or three hours, and there was a good chance that he might be hit again before he arrived at the Aid Post, for machine gun fire swept the ground intermittently all night. One important result of the new conditions was a great increase in patrolling. Now that large portions of the line were entirely deserted and posts were isolated from one another, this was very necessary, for at night the enemy could enter the trenches unseen almost as easily as the British could leave them. Most of this patrolling was purely defensive, but occasionally useful reconnaissances were made, one of which will be described in detail later. There was little opportunity for the men to show an offensive spirit. A little bombing was indulged in, but soon the general policy became one of “live and let live.” Had the enemy attempted an infantry advance the defence must have placed its main reliance on the bayonet; in that waste of mud rifles could not be kept properly clean, and few would have fired more than two or three rounds rapid.
