At 6 A.M. the advance began. Rain fell and continued intermittently during the three days' operations. The advance was much hampered, especially in the initial stages, by a creeping barrage put down by the Sixty-second Division, without any warning having been given to the Battalion. The going was very heavy, and the very enclosed country, intersected by thick hedges and wire fences, made it difficult for the companies to keep their directions. Little opposition was encountered, until the leading platoons reached Amfroipret, when one German officer and five men were taken prisoners in the village. Immediately east of the village and in the wooded country south of the railway, the Battalion began to encounter the enemy's rear-guard, but after driving it in some way the advance came to a standstill about the line of the road from Bout la Haut to Cambron Farm. The extraordinary difficulty of locating a hidden enemy in such an enclosed country made the advance hazardous, and the Germans appeared to be holding very strongly with machine-guns a line some five hundred yards east of this road. Lieutenant Kennaway, with No. 2 Company, attempted to secure the cross-roads in front of him, and failed to make any headway against the enemy's machine-guns. During this gallant attempt Lieutenant Lamont, who was with the leading platoon, was killed, in addition to many men. The situation was not without anxiety, for on neither flank could any British troops be seen. It looked as if the Battalion had been going on too fast for the rest of the line, and Lieutenant-Colonel Bailey decided to wait until the situation on the right developed. No. 2 Company accordingly dug in where it was, and the King's Company was moved to Cambron Farm to fill up the gap there was between the right of the line and the Sixty-second Division. The situation on the left required some adjustment, for the 2nd Battalion Scots Guards had been apparently held up, and No. 3 Company had to be responsible for that flank of the Battalion. About mid-day a company of the Scots Guards came up through the village, and occupied Bermeries without opposition, making the left flank once more secure. This enabled No. 4 Company to push forward through the orchards and drive out an enemy's post, but again the enemy's machine-guns prevented any farther advance. The difficulties in this action were that, when once a company or platoon had been sent off anywhere, it could not be found again owing to the enclosed nature of the country. No communication between the various parties was possible, and the operations therefore developed into small isolated parties fighting independently of each other. The Germans began to shell the village with heavy shell during the afternoon, and the front line posts were fired on at close range by field artillery. During the evening No. 3 Company took over the outpost line from No. 4 Company, which was withdrawn to cellars in the eastern end of the village.
