The Seventeenth Corps (Fergusson) was upon the left of the Sixth. Its right-hand unit, Lukin's Ninth Division, consisting of two Scottish and one South African brigade, was operating upon the immediate north of the Scarpe. This division was to attack with {37} three brigades in line, the 26th on the right, 27th on the left, and South Africans between. Upon the left of the Ninth was Nicholson's Thirty-fourth Division, drawn largely from Scotland and Tyneside, the same fine division which had been the very pivot upon which the battle of July 1 had turned. Upon the left of the corps was the Fifty-first Highland Territorial Division which had distinguished itself so greatly at Beaumont Hamel five months before. It may be said, therefore, that the fighting line of the Seventeenth Corps upon this great day was predominantly Scottish, but Lambton's veteran Fourth Division was in immediate support. The whole battle-front was from the right bank of the Scarpe near Arras up to the post known as the Commandant's House, just south of Thelus. There were no villages over the greater part of this front, but there were great numbers of fortified farms and strong posts of every description, besides the usual lines of wired trenches. The ground was in successive ridges and a big tactical obstacle existed in the Lens-Arras railroad in its alternate cuttings and embankments. The long eager line of Highlanders, Tynesiders, and South Africans rolled over every obstacle, and by ten o'clock had mastered all the first objectives, which were the three lines of German trenches. In the south the Ninth Division, led by a well-known South African Imperial soldier, had carried first Blangy and then Athies by storm. There was a time when the 26th Brigade upon the right was hung up, but with fine initiative the right flank of the Transvaal Regiment worked down along the railway cutting and helped to clear the front of its neighbours. In the centre, the Thirty-fourth Division, after a short check at a network {38} of trenches called "The Pump," had reached its allotted positions. In the north the clansmen, who as Territorials were sprung from the very soil of the Highlands, had swiftly advanced to the south of Thelus and had covered the right wing of the First Canadians while they captured that village. It was victory all along the line, and victory without those excessive losses which have made many of our greatest successes as tragic as they are glorious. The artillery barrage had been found to be a powerful antidote against the deadly machine-guns. "When our barrage lifted off the railway cutting, the machine-guns had been silenced and all the gunners were found to be dead." Such was the report of a South African officer.
