On 21 August, a battalion of the 41st Brigade attacked the German defences in the wood, obscured by smoke discharges on the flanks but the German defenders inflicted nearly by small-arms fire. At midnight, an attack by the 100th Brigade of the 33rd Division, from the Flers road to Wood Lane began but the right-hand battalion was informed too late and the left-hand battalion attacked alone and was repulsed. In a combined attack with the French from the Somme north to the XIV Corps and III Corps areas, XV Corps attacked to complete the capture of Delville Wood and consolidate from Beer Trench to Hop Alley and Wood Lane. The 14th Division operation was conducted by a battalion of the 41st Brigade and three from the 42nd Brigade.
