The trenches themselves did not exist as such, as in most cases they had been blown in.’ On the 15th, the thaw commenced, and in some respects was more intolerable than the frost. The mud in places was two feet deep, and reliefs and so on were considerably hampered. [Illustration] The shadow, or, rather, the light, of the coming German retreat lay over all. Every trench which was captured brought a wider view and a larger prospect into sight, and there is no doubt that the 62nd Division, to that extent more fortunate than the 49th, arrived at a time and in a locality which afforded, in business parlance, small turn-overs and quick returns. The long waiting experience which ate the heart out of constantly harassed troops was now, temporarily, if not definitely, passed; they were pushing outwards hopefully to open country and signs of the retreat occurred every day. Thus, on February 25th, at 2 o’clock in the morning, the enemy was reported to have vacated Serre, which, if a straight line be drawn from Albert to Arras, may be pricked in just to the left of that line at a point about two-fifths along it. Puisieux lies on the line just above Serre. Achiet-le-Petit, Achiet-le-Grand and Sapignies lie behind Puisieux eastwards, at distances roughly, of two miles. Miraumont is south of Puisieux, Irles south of Achiet-le-Petit, and Pys south of Irles. They are all in the Albert-Arras-Bapaume triangle within the shell-ridden quadrangle above. Let us start at Serre on that dark February morning. A push was made out and up towards Puisieux. There were strong positions to be negotiated: Gudgeon Trench, Sunken Road, Orchard Alley and Railway. Two patrols were sent out early on the 26th under subaltern Officers of the 2/4th King’s Own Yorkshire Light Infantry, and reported Gudgeon and Orchard trenches clear. Later, it was discovered that the patrol’s Gudgeon was a trench not shown on the map, and that the patrol’s Orchard was the true Gudgeon; mist and mud and an unmapped trench are ugly extras in patrol-work. Three Companies (A, B, D) of the Battalion were pushed up to the real Gudgeon trench with orders to put out posts on the Sunken Road in front and an observation-line on the Railway in front of that. They succeeded in placing two outposts, but machine-gun fire stopped the observation-line. There remained the heavily fortified Wundt Werk, which we have not yet mentioned, and which was held by C Company under the Officer Commanding the Battalion. Many fine deeds were performed on this day of continuous exposure to shell and rifle fire. A non-commissioned officer, for example, was sent forward to take charge of a small party, who had been badly knocked about. He kept them under cover in a shell-hole all the rest of the day, and by his coolness and trustworthiness undoubtedly saved their lives.
