The 5th Gordon Highlanders and 152nd Machine-Gun Company were ordered to assist this attack by flanking fire. It was also decided to send forward Stokes guns to the front line held by the 5th Gordon Highlanders to bombard the Brown line from a flank. Captain Amos of the 152nd Trench-Mortar Battery therefore went forward to select suitable gun positions, and found that the enemy were no longer holding the Brown line on the immediate left flank of the 5th Gordon Highlanders. Shortly afterwards, one of the Divisional observers, Corporal Mitchell of the 6th Gordon Highlanders, reported that he had made his way into the Brown line, and that it was unoccupied. He had found the electric light still burning in the dug-outs, packs and equipment neatly stacked, and unopened parcels and unfinished meals lying on the tables. Patrols from the 154th Brigade also returned with similar reports. The Brown line was then occupied without opposition, and the 9th Royal Scots and the 7th Gordon Highlanders pushed forward towards the railway. On the night of 11-12th April the 2nd Division relieved the Highland Division in an intense blizzard. So ended the first phase of the battle of Arras. The Division had finally reached all its objectives after some Homeric fighting. The losses had been heavy, but not heavier than an attack against so formidable a position held by such expert fighters would lead one to expect. Numbers of the enemy had been killed, and many hundreds taken prisoners. Large captures were also made of machine-guns, trench-mortars, and material and equipment; while on the whole battle front several Bavarian Divisions had been knocked out. In fact, the blow sustained by the enemy had been so great that after the relief the 2nd Division were able to carry out a substantial advance and occupy the village of Bailleul unopposed. On 12th April Divisional headquarters opened at Hermaville. The troops were, however, given a bare forty-eight hours in which to rest, clean up, refit, and reorganise before they were again called upon. CHAPTER X. THE BATTLE OF ARRAS (_Contd._)--ROEUX AND THE CHEMICAL WORKS. On the night of 15-16th April the Division relieved the 9th Division on the battle front east of Fampoux, with its right resting on the river Scarpe. The reserve brigade was quartered in Arras, this being the first occasion on which any of the Division had occupied billets in that town. During the next six weeks the Jocks were continually moving into Arras for short periods of rest, and they became much attached to it.
