September 6 and 7 were occupied in a slow but steady advance which absorbed Equancourt, Fins, and Sorel-le-Grand. On September 8 matters were less one-sided, as the Twenty-first Division, acting in close liaison with Rawlinson at Peizières, attacked Vaucelette Farm and Chapel Crossing. It {95} must have been with peculiar ardour and joy that General Campbell and his men flung themselves upon the positions which they had held so heroically upon March 21. Here after six months were their complete vindication and revenge. The fighting was carried on into September 9, the Seventeenth Division joining in on the left in close touch with the New Zealanders of the Fourth Corps. It was clear that the Germans meant standing if they could and the struggle was a very hard one, but before evening much of the ground had reverted to the two divisions which were both, by a peculiar coincidence, more or less in their old positions. There were attack and counter-attack, and a good price paid for all that was gained. There are days when land is cheap and days when it is the dearest thing upon earth. At the end of this fight the Germans were in a continuous trench on one side of the ridge and the British in a corresponding position on the other. It became more and more clear that the days of pursuit and rearguard actions were over, and that the whole British front in this quarter was up against a fixed battle position of the enemy--or at the least against the strong outposts in front of a fixed battle position. This important fact regulates the whole situation up to the great attack of September 29. [Sidenote: Sept. 10-18.] September 10 and 11 were spent in local encounters in the Chapel Crossing and Vaucelette Farm district, the Germans striving hard by these outpost engagements to prevent the British line from getting within striking distance of the old Hindenburg position, behind which they hoped to rally their dishevelled forces. The British were equally eager to break {96} down this screen and get at the solid proposition behind it. The weather was terrible, rising at one time to the height of a cyclone, which disarranged serious British advance, the Fourth Corps on the left attacking the Trescault Spur, while the Welsh, who had now relieved the Seventeenth Division, were to go forward on their flank. The Germans clung desperately to their ground, however, and after a long day of alternate advance and retreat the British line was where it had been in the morning. A position called African Trench lay in front of the Welshmen, and it was not possible to carry it in face of the very severe machine-gun fire. From this date until September 18 there was no advance and no change on the front of the Fifth Corps save that Pinney's Thirty-third Division came in to patch its worn array. [Sidenote: Sept. 18.]
