Harrington, a machine-gunner of No. 1 Company, went out with him and the gun was brought in. A further advance was made in the afternoon to the edge of the wood in order to clear out the snipers who held it and commanded the cultivated fields outside. Towards dusk, Captain Lord Guernsey, who was Acting Quartermaster, reported himself to the C.O., who posted him to No. 2 Company, then engaged in clearing out the snipers, in place of Captain Guthrie, who had been wounded. He went forward to assist Captain Lord Arthur Hay in command, and both were immediately shot dead. The Battalion bivouacked in battle-outpost formation that night on the edge of the wood, and got into touch with the 60th Rifles on their right and the 2nd Grenadiers on their left. Here, though they did not know it, the advance from the Marne was at an end. Our forces had reached the valley of the Aisne, with its bluffs on either side and deep roads half hidden by the woods that climbed them. The plateaux of the north of the river shaped themselves for the trench-warfare of the years to come; and the natural strength of the positions on the high ground was increased by numberless quarries and caves that ran along it. THE HALT AT SOUPIR On the 15th September patrols reported that the enemy had fallen back a little from his position, and at daylight two companies entrenched themselves on the edge of the wood. Judged by present standards those trenches were little more than shallow furrows, for we did not know that the day of open battle was ended, and it is curious to see how slowly our people broke themselves to the monotonous business of trench construction and maintenance. Even after they had dug the casual ditch which they called a trench, it cost some time and a few lives till they understood that the works could not be approached in the open as had been war’s custom. Their first communication-trench was but three hundred yards long, and it struck them as a gigantic and almost impossible “fatigue.” The enemy had not fallen back more than a thousand yards from the Cour de Soupir farm which they were resolute to retake if possible. They fired on our burying-parties and shelled the trenches all through the 16th September. Patrols were sent out at dawn and dusk--since any one visible leaving the trenches was fired upon by snipers--found hostile infantry in full strength in front of them, and the Battalion had to organize its first system of trench-relief; for the Diary of the 18th September remarks that “Nos. 1 and 4 Companies relieved 2 and 3 Companies in the trenches and were again shelled during the day.”
