Very stiff lighting was in progress on this sector, as we were now nearing the summit of the Ridge, the possession of which would be invaluable, as the enemy’s territory would be laid bare to us, and he would lose his observation over us. It was not surprising, therefore, that he fought with the courage of despair and initiated counter-attack upon counter-attack, all of which we had to meet with great determination. The weather was extremely hot, which added much to the discomfort: and, as progress had been very slow for some time, it was impossible to clear up the battlefield, and the stench was almost insupportable. At length the village of Guinchy was captured, and, with our men installed on the further side of the slope, the fighting for position came to an end. We were now entering on the third stage of the great battle, which had commenced more than two months previously. An attack, on a large scale, was planned, the object being to drive the enemy down the slope of the hill into the low-lying country beyond. Field batteries were moved up into forward positions, in order to assist the infantry, by placing a creeping barrage—a new and most successful invention, afterwards employed on all occasions—in front of the advancing waves of men: and the “heavies,” of which, for the first time, we possessed a preponderance, pounded the enemy communications far behind his lines. The assault was delivered over a wide area, early in the morning of the 15th of September, but in no way did it come up to expectations—in fact, it might almost be counted a reverse. Some divisions did well, and took their objectives, but others were completely held up, at certain strong points, which necessitated the withdrawal of the remainder, in order to keep the line uniform. The Guards met with instant success, and took their final objectives, only to discover that the Division on each side of them had made little progress and could get no further. They were reluctantly forced to return, and it was while doing so that heavy casualties were inflicted on them, as they were raked with fire from the sides as well as in front. During the withdrawal, a party of machine-gunners occupied a trench, and attempted to screen the retirement of the main body of troops, by holding the enemy at bay. In order to use this machine-gun to the best advantage, the piece was placed on top of the parapet, exposed to the full view of the oncoming hordes, but our men never wavered in serving it, and, as soon as one gunner dropped at his post, another instantly took the vacant place, although it meant certain death within a few moments.
