The British attack was, too, largely on the field of a former attack in 1917, but there was this difference: the Canadians had smashed through the Quéant-Drocourt system on the left. This would make the attack on the Bourlon Wood positions somewhat easier. But the whole system of defence round and about the Hindenburg Line varied in depth between 7,000 and 10,000 yards, and was a most formidable series of fortifications.
The First and Third Armies attacked with the IV, VI, XVII, and Canadian Corps, the operation of the 56th Division being on the extreme left and subsequent to the launching of the main attack. The problem on the left, which the 56th Division helped to solve, was that the northern portion of the canal was too formidable an obstacle to be crossed in the face of the enemy, and it was therefore necessary to force a passage on the narrow front about Mœuvres, and turn the line of the canal farther north by a divergent attack developed fan-wise from the point of crossing.
The morning broke wet and misty. The wind was
from the west, and carried the opening crash of the British barrage, at 5.30 a.m., well behind the German lines. But they did not need this sort of warning. For days they had watched the assembling of batteries, stores, a gigantic army behind the infantry, who were ever keeping a steady pressure on their advanced lines. Prepared as they were, however, nothing could stop the assaulting lines of Canadians. News came in to the 56th Division early that all was going well.
Enemy retaliation on the 56th Division was slight, and practically ceased by 5.40 a.m. But as the morning progressed it became apparent that the Canadians were meeting with strong opposition on the extreme left. They were timed to reach a line immediately south of Sauchy by mid-day, and the 169th Brigade was to carry on the attack from there at 2.48 p.m.
Brig.-Gen. Coke ordered the London Rifle Brigade to send a company, as soon as the barrage would permit, to establish posts on the east bank of the canal, and cover the Royal Engineers, who were to build a bridge about 1,000 yards north of the Arras-Cambrai road. A similar bridge was to be made some 300 yards south of the road. The northern bridge was to be complete by 11 a.m. and the southern one by mid-day. But the village of Marquion was on the east of the canal, and on the Arras-Cambrai road, and at 11.45 a.m. the village was still holding out, which made it impossible for the 169th Brigade to keep to the time-table and be in position for attack by 2.48 p.m. It was therefore decided to postpone the attack until 3.28 p.m.
Meanwhile, the Engineers (513th Coy. and 512th
Coy.) and Pioneers had gone forward to construct their bridges, and had found themselves opposed by hostile infantry. They, however, cleared the eastern bank and commenced to build.
At mid-day it was reported that Marquion was clear, and the 2nd London Regt. started to cross about that time, followed by the Queen’s Westminsters and the London Rifle Brigade. The advance of the 169th Brigade to the assembly positions completed the clearing of the ground behind the Canadians—the Queen’s Westminsters capturing no less than 50 prisoners from fighting groups they met with before forming up.
At three o’clock the brigade was in position with the 2nd Londons on the right and the Queen’s Westminsters on the left. The London Rifle Brigade had one company between the two branches of the River Agache clearing up the ground, and two companies in support of the 2nd Londons; the fourth company was engaged in covering the Engineers, who were making the northern bridge.
