In this position he was pinned. He first attempted to develop an attack southwards from his south-east corner of the chemical works. This attempt was defeated by a company of the 8th Argyll and Sutherland Highlanders, who, seeing the enemy in their rear, left their trenches, charged them, and routed them. This company, which suffered severe casualties, was led by Captain A. Mactaggart. No officer could have shown a finer example to his men. His right hand was shattered by a fragment of a shell early in the attack. Subsequently, owing to a second shell wound, he lost an eye. Nevertheless, he continued to lead and encourage his men until he was mortally wounded, and could continue no farther. Mactaggart’s complete disregard for the pain of his wounds and for his own personal danger, and his devotion to duty, may perhaps have been equalled, but can never have been surpassed. Even as he lay mortally wounded with a gaping wound in the abdomen, he continued urging on his men until he lost consciousness.
A second attack of the same nature was stopped by the rifle and Lewis-gun fire of the 5th Seaforth Highlanders and a Vickers gun. Covering fire was then arranged, under which a bombing party advanced, forced the enemy to retire across the open, and captured 1 officer and 20 other ranks.
In the course of these operations the troops, led by the junior officers and N.C.O.’s, had so disposed themselves that the enemy could not develop his advance in any direction except by delivering a frontal attack. Before the enemy had time to bring up fresh troops with which to deliver further attacks, Lieut.-Colonel R. Campbell, D.S.O., commanding 8th Argyll and Sutherland Highlanders, personally organised a counter-attack which restored to us the whole of our line south of the railway.
Colonel Campbell, realising that the Germans had made a deep penetration into our lines, fell in the personnel of his battalion headquarters, and assisted by Captain Pollard, his bombing officer; Lieutenant Worlock, his Lewis-gun officer; Captain A. MacDonald, the adjutant; and Captain Fairlie, his artillery liaison officer, delivered an immediate counter-attack against the Germans north of the railway. This attack was delivered as follows: Captain Pollard, a skilful bomber, drove the enemy from his shell-holes with rifle grenades, while the remainder of the party shot them down as they ran. Colonel Campbell himself killed six Germans with his rifle.
By 6.45 A.M. he had killed or captured all Germans on the north side of the railway. However, about this hour he heard heavy rifle-fire taking place on the south side. He therefore led his party on to the embankment, from which he saw a party of Germans just west of the chemical works being engaged by the 6th Seaforth Highlanders both from their front and from their left flank with rifle-fire.
Colonel Campbell immediately sent his adjutant to tell the 6th Seaforth Highlanders to deliver a frontal attack while he enfiladed the Germans from the embankment. This operation was carried out with complete success. Captain Pollard was, however, killed by a bullet which passed through his heart. Colonel Campbell narrowly escaped a similar fate, a bullet flattening itself against the railway line on which his chest was resting as he fired.
Colonel Campbell then joined the 6th Seaforth Highlanders with his party, advanced through the chemical works with them, and dug himself in just east of them.
Meanwhile Captain Donald Clarke, M.C., of the 6th Gordon Highlanders, had also organised a counter-attack, and with men of the 6th Gordon Highlanders and 5th and 6th Seaforth Highlanders carried out a sweep forward covering the whole of the brigade front south of the chemical works. The advance of this force made great progress except in Roeux village, where it was checked for a time by a heavy enemy barrage. On the rest of the front over which they advanced they reached the foremost British lines. Here Captain Clarke reorganised his troops and disposed them in depth. He found the front line still occupied by its original garrison. These troops had not been shelled either during the actual attack or in the preliminary bombardment, the enemy doubtless not having discovered their position. In the grey of the dawn, they had seen by the assistance of Very lights large numbers of the enemy advancing in small columns to the attack. Vickers and Lewis guns and riflemen opened on them, and fired round after round into them, thus bringing the advance to a complete standstill, and killing large numbers of the enemy. As it became lighter, the enemy repeated his attempts to advance, on this occasion adopting an extended formation. Again these men, who had not been shaken by any previous bombardment, steadily engaged the splendid targets offered them, and annihilated the attacking force. The Vickers guns in particular played tremendous havoc with the enemy, and the policy of pushing them well forward, though often condemned, proved in this case to have been amply justified. No further attacks were delivered against the front of these two companies.
Meanwhile all telephone wires were cut, and information was extremely difficult to obtain. The enemy’s barrage had now lifted on to the area between the river Scarpe and brigade headquarters, and numbers of runners were killed in trying to pass through it.
Prisoners and wounded men on their way to the dressing stations had, however, reported that the Germans had captured the chemical works. Arrangements had therefore been made to counter-attack behind a barrage with a view to recapturing the works. The 5th Gordon Highlanders, having been placed at General Burn’s disposal, were detailed to carry out this attack.
