On the following day, August 9, 1918, the advance was continued, with the Third, First, and Second Canadian Divisions in the line, the Fourth Canadian Division being held in corps reserve. Substantial progress was made, and by evening the average depth of advance was about four miles, with a maximum of six and one half miles at some points. The following additional villages were captured: Le Quesnel, Folies, Bouchoir, Beaufort, Warvillers, Rouvroy, Vrely, Meharicourt, and Rosières. The infantry and tanks of the Third Canadian Division and the Canadian Independent Force cooperated with the French in the capture of Arvillers. During the day the enemy's resistance stiffened considerably, and whatever gains were made resulted from heavy infantry fighting against fresh troops, with only a few tanks available for support. The attack was continued on the morning of the 10th, with the Third Canadian Division on the right and the Fourth Canadian Division on the left, the First and Second Canadian Divisions being held in corps reserve. After the Third Canadian Division had taken the village of Le Quesnoy-en-Santerre, the Thirty-second Division, which had come under the Canadian Corps on the night of the 9th-10th, and had been ordered to relieve the Third Canadian Division, passed through it and advanced the line somewhat farther through the old British trenches west of Parvillers and Damery. The Fourth Canadian Division during the day succeeded, after very hard fighting, in occupying Fouquescourt, Maucourt, Chilly, and Hallu. During the night 10th-11th a strong enemy counterattack developed against a part of the front of the Fourth Canadian Division east of Hallu. This counterattack was beaten off, but owing to general conditions the line at that point was slightly withdrawn to the railway embankment immediately to the west of Hallu. Subsequent upon this slight withdrawal, and with a view to reducing the existing salient forward of Chilly, the line was further withdrawn to the eastern outskirts of that village. On August 11, 1918, at 9.30 a. m., the Thirty-second Division launched an attack against Damery, but was not successful. The Fourth Canadian Division improved their line by advancing it locally to reduce the Chilly salient, which was still very pronounced. During the night of August 12, 1918, the Thirty-second Division and Fourth Canadian Division were relieved by the Third and Second Canadian Divisions respectively. It now became increasingly apparent that strong enemy reserves had been sent forward to stem the Canadian advance. Six fresh divisions and a large number of light and heavy batteries had been brought in, and were fighting hard in a strongly intrenched defensive position.
