The share of the Guards Division in the northern attack was to cross the Canal du Nord at Lock Seven, north of Havrincourt, on a front of a mile; then work through the complicated tangle of the Hindenburg support line directly east along the ridge from Flesquières village to Premy Chapel which stands at the junction of the roads from Noyelles, Marcoing, and Graincourt, and to consolidate on the line of the Marcoing-Graincourt road. Meantime, the Third Division on their right would take the village of Flesquières; the Fifty-second Division would take the Hindenburg Line that lay west of the Canal in the bend of it, and would then let the Sixty-third through who would swing down from the north and attend to Graincourt and Anneux villages. The total advance set for the Guards Division was three miles, but, if the operations were fully successful, they were to push on to the outskirts of Noyelles; the Third Division to Marcoing; while the Fifty-seventh, coming through the Sixty-third, would take Cantaing and Fontaine-Notre-Dame. In the Guards Division itself, the 2nd Brigade was to move off first, and ferret its way through a knot of heavily wired trenches that lay between them and the Canal, take the Hindenburg support trenches, and then form a defensive flank to the left of the next advance till the Fifty-second and Sixty-third Divisions should have secured Graincourt. The 1st Brigade would pass through them and capture the trenches across the Canal to the north and north-east of Flesquières. If resistance were not too strong, that brigade was to go on to the spur running from Flesquières to Cantaing, and help the Sixty-third turn the Graincourt line. The 3rd Brigade, passing through the 1st, would carry on and take the high ground round Premy Chapel.
