It was clear now that the Germans, either of their own will or driven by the constant pressure, were withdrawing their rearguards, so that in the early morning of September 3 no touch could be gained by patrols. By 6 A.M. the British advance guards were well on their way, streaming forward to the {94} Canal du Nord, from the eastern bank of which the eternal machine-guns were rapping away once more, stopping the 50th Brigade in an attempt to make a direct advance. There were no bridges left, so nothing further could be done that day, which brought the corps front up to the western bank from Manancourt to the north-east of Etricourt. On September 4, however, the crossing was effected without any very great difficulty, and bridge-heads established by both the divisions in the line. On September 5 the 114th Brigade attacked the trench system round Equancourt without success. The 51st Brigade had better luck to the north of the village and gained a good bit of ground. The 7th Lincolns were held up with considerable loss in the first advance on account of some misunderstanding about the starting-point and insufficient touch with the Forty-second Division on their left. The 7th Borders, a battalion made up of Cumberland and Westmoreland Yeomanry, carried on the attack and found the village deserted. The day ended with the right flank of the Fifth Corps in touch with the Third Corps to the north-west of Nurlu, while the left flank joined the Fourth Corps north of Vallulart Wood. That night the Twenty-first Division came back into line, taking the place of the Welshmen who had done such splendid and strenuous service since August 22. [Sidenote: Sept. 6-10.]
