On the 56th (1/1st London) Division front, the final objective was about into Polygon Wood. On the right, the 53rd Brigade of the 18th (Eastern) Division was to advance from Stirling Castle, through Inverness Copse to Black Watch Corner, at the south-west corner of Polygon Wood, to form a defensive flank to the south. Further north, the 169th Brigade was to advance to Polygon Wood through Glencorse Wood and 167th Brigade was to reach the north-western part of Polygon Wood through Nonne Bosschen. The 8th Division was to attack with two brigades between Westhoek and the Ypres–Roulers railway, to reach the green line on the rise east of the Hanebeek stream. Eight tanks were allotted to II Corps to assist the infantry. The artillery support for the attack was the same as that for 10 August, guns for the creeping barrage moving at in five minutes, with howitzers and placing standing barrages beyond the final objective. Eight machine-gun companies were to fire barrages on the area from the north-east of Polygon Wood to west of Zonnebeke.
