The result of the first day of Arras was that all the enemy’s front positions had gone, and his final position, short of the Drocourt-Quéant line, had been breached on a front of 2½ miles. Unfortunately the weather became his ally. It changed to intense cold and wet, and with the sodden ground it took long to bring up our guns. He held us up with machine guns in pockets of the ground, which prevented the use of our cavalry, and there was no chance of a dramatic _coup de grâce_. The infantry could only push forward slowly and methodically, and complete the capture of the remains of his position. We had made a breach, a genuine breach, on a broad front in his line, but we could not exploit our success owing to the nature of the ground and the weather. Our remarkable gains, won at small cost the first day, could only be increased by small daily additions, for the elaborate preliminaries of Arras could not be improvised, and the infantry must wait on the advance of the guns. [Sidenote: _April 10._] [Sidenote: _April 11._] Tuesday, 10th April, was spent by the South African Brigade in the Blue and Black lines, in cleaning rifles and equipment and replenishing ammunition. The Brigade was then placed at the disposal of the 4th Division, and early on Wednesday, the 11th, orders were received for it to relieve the 10th Brigade, which was then holding the Brown Line. That day Lambton was attacking at noon, and the 1st and 2nd South African Regiments moved up to a forward post under cover of a ridge 500 yards behind the Green Line to act in support. The attack of the 4th Division gained some ground, but failed in its main purpose; and after dark the 1st, 2nd, and 4th South African Regiments took up a position running north-west from Fampoux, with the 3rd Regiment in reserve. At that moment the enemy held a line running from south to north from Rœux through the Chemical Works and the railway station along the Gavrelle road. Behind it to the east lay the slopes of Greenland Hill. An attack was ordered for the following day against this position. The 9th Division was to advance against the line between Rœux and the roadside inn which lay a thousand yards east of the Hyderabad Redoubt, with the 15th Division holding the front south of the Scarpe, and the 4th Division to protect the northern flank of the attack. There were two objectives—the first being the road from the inn to the station; and the second, the Chemical Works and buildings south of the railway, the wood called Mount Pleasant, and the village of Rœux. The South African Brigade on the right and the 27th Brigade on their left were to capture the first objective, after which the 26th Brigade would advance south of the railway. [Sidenote: _April 12._]
