The units immediately concerned were the 4th and 5th Battalions, West Riding Regiment, and the 6th and 8th Battalions, West Yorks. The 7th Battalion of each Regiment was stationed in reserve. The week’s casualties in the Division were high: OFFICERS. OTHER RANKS. Killed 14 196 Wounded 47 994 Missing 17 611 -- ---- 78 1801 -- ---- Total 1879 and the bulk of them occurred on September 3rd. The large percentage of missing in all ranks (more than a third of the whole) seems to indicate a hasty retreat from untenable positions. The presumption is borne out by Battalion records. These agree that co-operation was interrupted by a bad block in communication, and that Battalions were not able to render one another all the support that was expected. Each unit tended to believe that its own advance was held up, or, rather, that its withdrawal was necessitated, by what had happened on its right or left; and, consequently, the exploits of individuals were more conspicuous than the conduct of the attack. Zero hour was 5-10 a.m., and the Companies left the trenches punctually and went over in good order. But the half-light caused some confusion, and communication proved very difficult. In the instance of several Battalions no definite news was received for three hours or more. Runners failed to get through, and rumours were not satisfactory. At last, about 9 o’clock, tidings began to arrive of heavy losses incurred in trying to consolidate captured positions under a cross enfilade of machine-gun and rifle fire. Remnants of Companies, driven back after a long morning’s heavy fighting told of the exhaustion of their bombs, and of their messages lost in No Man’s Land. Stray parties cut off in the attack, found cover in shell-holes until nightfall. One Commanding Officer frankly wrote, ‘the whole attack failed.’ ‘The objectives were gained,’ he summed up, ‘but the first casualties in Officers and N.C.O.’s were heavy, and therefore the men with power of “leadership” were lost when most needed to hold on. The presence of the enemy in the Pope’s Nose (a machine-gun nest at an early point) upset all chances of reinforcements and supply except across the open’—an almost impossible condition. The runners, as we saw, did not get across, and the light was too bad for the observation posts to give effective help. On the other hand, the daylight was too strong to consolidate under fire the battered German trenches which had been captured. There was, unfortunately, a ‘but’ or an ‘if’ which qualified every record of success; and we may quote the following statement from a Battalion Diary, which gives a very fair impression of the whole episode:
