Fully alive to the gravity of the situation which would be created on the flank of the Third Army by the failure to capture and hold Bourlon Wood, the Fourth Canadian Division attacked from the north side of the wood and captured all the high ground, pushing patrols as far as Fontaine-Notre-Dame. Bourlon Wood, which is 110 meters high, dominates the ground as far south as Flequières and Havrincourt; its loss after very heavy fighting in November, 1917, during the first battle of Cambrai, caused eventually the withdrawal of the Third Army from a large portion of the ground they had won by their surprise attack. A severe counterattack, launched from the direction of Raillencourt against the left of the Fourth Canadian Division, was repulsed in the afternoon with heavy losses to the enemy. The First Canadian Division and the Eleventh (British) Division made substantial gains, the former capturing Haynecourt and crossing the Douai-Cambrai road, and the latter pushing on and taking Epinoy and Oisy-le-Verger by evening. The attack was continued on September 28, 1918. The Third Canadian Division captured Fontaine-Notre-Dame (one of the Seventeenth Corps' objectives) and, penetrating the Marcoing line, reached the western outskirts of St.-Olle. The Fourth Canadian Division captured Raillencourt and Sailly, and the Eleventh (British) Division established posts in Aubencheul-au-Bac and occupied the Bois-de-Quesnoy. The First Canadian Division, in view of their advance of the previous day which had produced a considerable salient, did not push forward. Heavy fighting characterized September 29, 1918. The Third Canadian Division, the Fourth Canadian Division, and the First Canadian Division all made progress in the face of severe opposition. The Third Canadian Division pushed the line forward to the junction of the Arras and Bapaume road, the western outskirts of Neuville St.-Remy and the Douai-Cambrai road. They also cleared the Marquion line from the Bapaume-Cambrai road southward toward the Canal-de-l'Escaut. The Fourth Canadian Division captured Sancourt, crossed the Douai-Cambrai railway and entered Blecourt, but later withdrew to the line of the railway in the face of a heavy counterattack.
