At scarcely any period of the war could the neighbourhood of Ypres be called quiet. In the autumn of 1915 the British held only a small bridge-head to the east of the Ypres-Commines Canal. Frequent attempts were made to extend this, and the enemy was just as anxious to drive the British out of the salient altogether. When the Battalion arrived in the area things had barely settled down after the Second Battle of Ypres, in which the enemy had won for himself all the commanding ridges, except Mont Kemmel. Since then minor operations had kept the front lively. One of these took place near Boesinghe only two days before the 49th Division took over the line, and the 148th Infantry Brigade in particular came in for a good share of the “liveliness” which followed it. On July 7th, the Battalion moved to Canada Wood, near Elverdinghe, where one night was spent. The next evening it relieved the 2nd Battalion Royal Dublin Fusiliers in the Lancashire Farm Sector. In spite of the narrowness of many of the trenches, the relief passed off very quickly. As the Battalion filed in the Dublins filed out, only too glad to hand over their charge to someone else. The 49th Division now held the extreme left sector of the British line. Its left rested on the Ypres-Commines Canal near Boesinghe, abutting on the French, whose line however was west of the canal. The 6th Division was on the right. The dominating feature of the sector was the Pilkem Ridge; this was entirely in the hands of the enemy, who thus possessed every advantage of high command and superior observation. This sector the 49th Division was destined to hold until the end of December--six months of continuous trench duty in the very worst part of the British line. Reliefs were so arranged that two brigades held the line while the third was back in rest. Thus the Battalion found itself in several different sub-sectors during its stay in the Ypres Salient. On every sector the defence scheme was simplicity itself--the front line was to be held at all costs; not an inch of ground was to be lost. During the first tour in the Lancashire Farm Sector A and D Companies held the front line, B Company was in support, and C Company in reserve. One of the main features of the sub-sector, and indeed of the whole divisional front, was the confusing network of old and disused trenches. Many of these had been hastily dug in the heat of battle and afterwards abandoned when they were found to be badly sited. Some, however, were gradually being incorporated in the regular system. The original notes on the sector, which were handed over by the Commanding Officer of the Dublins, have been preserved; their outstanding feature is the continual reference to “work to be done.” He was right. Never did the Battalion find itself harder worked than during the next few months.
