Towards the evening the enemy's success on the left began to make itself felt, strong pressure being brought against the Division from the north. Just before 6 P.M. a heavy attack developed. The 7th Black Watch were engaged from both sides of the Beaumetz line, and were driven back into the Beaumetz-Morchies road, where a company of the 8th Royal Scots were already in position, and had been doing fine work with their rifles. The remnants of the company of the 6th Black Watch in the gun-pits (see p. 279) were cut off from the Beaumetz-Morchies line, and fell back in a southerly direction, lining the Bapaume-Cambrai road. Here they were reinforced by a platoon of the 8th Royal Scots and the remnants of the 7th Gordon Highlanders, and were supported in rear by men of the 6th Gordon Highlanders and 6th Seaforth Highlanders, lining the Beaumetz-Doignies road. These movements had become necessary, as the turning of the Beaumetz-Morchies line and the enemy's progress on the left was compelling us to change front and face north. The enemy advanced as far as the Cambrai road, which he lined on the side opposite to our troops; and though a certain amount of bombing took place, he made no serious attempt to cross it. With a view to opposing the enemy's advance more frontally, orders were issued for the evacuation of the Corps line north of Beaumetz, and for the taking up of a new line covering Lebucquière and Velu, the remnants of the 153rd Brigade, the 8th Royal Scots, and the 6th Gordon Highlanders being withdrawn into Divisional reserve at Fremicourt under the command of the B.G.C. 153rd Brigade. The line then ran from Hermies along the Hermies Switch to the Beaumetz line, thence along the Beaumetz line, from which it bent back between Beaumetz and Lebucquière, to a point west of Chaufours Wood. The 154th Brigade, with the 8th Gloucesters and 10th Warwicks of the 57th Brigade (19th Division) on the right, held this line as far as the southern corner of Beaumetz; next to them came the 152nd Brigade, with the 10th Warwicks and 401st and 404th Field Companies, thence the line was continued to the Divisional left boundary by the 34th Brigade (23rd Division), with the 11th Cheshires. The 58th Brigade (19th Division) and the 400th Field Company were in position to the north of Beugny, and also extended the left of the Divisional line towards Morchies. During the evening, owing to the uncertainty of the situation in the north, Divisional headquarters moved to tents at Bancourt, and thence to the late Corps headquarters at Grévillers, while all three brigades moved their headquarters to the old Divisional H.Q. at Fremicourt. Early in the morning of the 23rd the Division was warned that events in the south were such that their withdrawal to the Army line would become necessary, and that if that were to take place by day, the 154th Brigade were to conform to the movements of the 17th Division on their right.
