The Seventy-fourth had now taken over from the Fifty-eighth Division. They were pushed at once into heavy fighting, advancing rapidly down the western slope of the Tortille valley, through Moislains, and over the canal. In their eager zeal they had not mopped up sufficiently, and they soon found themselves under a fire from front and rear which no troops could endure. They were driven back to near the point from which they started and their losses were considerable. The Australians formed a defensive flank on the south, and the Forty-seventh on the north, and a line of resistance was built up between them from Haut Allaines on the right to the western bank of the Tortille. The Yeomanry had before evening endured a very terrible welcome to the Western front. The Eighteenth Division on the left had also had some severe fighting which fell chiefly upon the depleted 53rd Brigade. It secured the high ground in the north of St. Pierre Vaast Wood, the whole of which was cleared by the 8th Berkshires. On September 3 and 4 the division continued to advance across the canal and the Tortille upon the line of Nurlu. On the evening of September 4 its long term of hard and glorious service was ended and the {62} Twelfth Division took its place. Its losses had been 2700, while it had captured during the battle some 1800 prisoners and many guns. [Sidenote: Sept. 2-10.] From this date until September 10, which saw them in front of the outposts of the Hindenburg Line, the record of the Third Corps was one of steady and uninterrupted progress. The German machine-guns were now, as always, a cause of constant worry, loss, and delay, but the remorseless drive of the British infantry was for ever beating in the obstinate rearguards. September 6 marked an advance of nearly three miles along the whole Corps front, the Twelfth, Forty-seventh, and Seventy-fourth moving in line and flooding over the village sites of Nurlu, Templeux, Driencourt, and Longavesnes. The work of Owen's 35th Brigade at Nurlu was particularly trying, for it was held up by wire and machine-guns, the 7th Sussex, 7th Norfolks, and 9th Essex all losing heavily in some very desperate fighting which gave little result. Finally, on September 6, the 1st Cambridge and 5th Berkshires reinforced the troops already mentioned and, under a renewed barrage, they broke the line and carried the position. On this date the Forty-seventh Londoners, who had done such solid work, were ordered off to join another corps, the Fifty-eighth moving up once more to take their place.
