In early October, the 39th Division took over from the 18th Division. Attacks by RIR 110 of the 28th Reserve Division, which had relieved the 26th Reserve Division, were made from The German attacks were supported by detachments and repulsed by two 117th Brigade battalions. At the 16th Sherwood Foresters made a surprise attack over ground, on the northern face beyond the crest, as the trenches had filled with mud but the Germans were waiting and repulsed the attack. On 14 October, the 4th/5th Black Watch, the 1st Cambridge and the 17th King's Royal Rifle Corps of the 117th Brigade, attacked the north side of the redoubt. The troops advanced over the open and captured the last part of the redoubt by taking about of II Battalion, RIR 110. Three German counter-attacks on 15 October, supported by detachments were defeated. A German attack on Redoubt, early on 21 October was repulsed and a British attack planned for the afternoon caught the Germans while still disorganised. Observers from 4 Squadron and 7 Squadron RFC watched the attack and directed artillery fire on German guns with zone calls, intended to suppress as much German artillery as possible rather than to destroy just a few guns.
