The 23rd Division infantry and engineers spent the night consolidating the Le Sars defences and preparing for the attack with the Canadians, which had been postponed to 8 October. Two battalions formed carrying parties and two more cleared out 26th Avenue, the only communication trench in the area. The delayed 69th Brigade attack on Flers Trench and Flers Support to the north of the village was prepared overnight. To meet the attack of the 2nd Canadian Division and to capture a quarry behind the German trenches, two companies of the 8th York and Lancaster Regiment (8th York and Lancs), which had been attached to the 69th Brigade, took over on the divisional left flank during the night. Each company had a Stokes mortar and the Flers trenches were bombarded all night by the 23rd Division artillery. The Canadian attack on Regina trench began at and the York and Lancs companies began to bomb along the trenches as soon as the barrage lifted. The attack succeeded swiftly and fifty prisoners and three machine-guns were captured, touch was gained with the Canadians and the quarry reconnoitred. It was found to be overlooked from German positions so a post was dug nearby in sheltered ground to overlook the area. A German counter-attack forced back the Canadians, leaving the 23rd Division flank open but no attack followed.
