From the Harp, which it will be remembered was the original line, to east of Monchy there runs a ridge of an average height of 100 metres; at Monchy itself it rises above 110 metres. This ridge shoots out a number of spurs towards the Cojeul River to the south. The position taken over by the 167th Brigade was from a small copse south-east of Monchy to the Arras-Cambrai road, about 500 yards from the Cojeul, and on the reverse slope of one of these spurs.
Observation for them was bad, and the enemy trenches were well sited and frequently over the crest of the hill.
On the 29th the 169th Brigade took over the right of the line from the 167th. The front line was then held by the London Rifle Brigade, the 2nd London Regt., the 1st London Regt., and the 7th Middlesex Regiment. The Queen Victoria’s Rifles were in support of the Queen’s Westminster Rifles in reserve to the right brigade, and the 3rd London Regt. in support and the 8th Middlesex Regt. in reserve to the left brigade.
With a view to the important operations which the French were to carry out on the 5th May, it was decided to attack on an extended front at Arras on the 3rd. While the Third and First Armies attacked from Fontaine-les-Croisilles to Fresnoy, the Fifth Army launched an attack on the Hindenburg Line about Bullecourt. This gave a total front of over sixteen miles. [The Third Battle of the Scarpe, 1917.]
Zero hour was 3.45 a.m., and in the darkness, illumined by wavering star-shells fired by a startled enemy, and with the crashing of the barrage, the men of the 56th Division advanced from their assembly trenches. As soon as the first waves topped the crest, they were met with a withering machine-gun and rifle fire. The ground was confusing and the darkness intense—officers, as was so often the case in night attacks, found it impossible to direct their men. Exactly what happened will never be known in detail. No reports came in for a considerable time.
With daylight the artillery observation officers began to communicate with headquarters. Our men,
they said, had advanced 1,000 yards on the right, and were digging in near a factory (Rohart) on the bank of the Cojeul, and the 14th Division on their right seemed to have reached its objectives. About 300 yards over the crest of the spur was a trench known as Tool, and this seemed to be occupied by the enemy.
Soon after this the 169th Brigade reported that the London Rifle Brigade were holding a pit near the factory and a trench about the same place; the 2nd London Regt. had a footing in Tool Trench. The latter position is doubtful, but the 2nd Londons were well forward.
Cavalry Farm, near and to the right of the original line, was still held by the enemy, and about 10 o’clock the Queen Victoria’s Rifles, after a short bombardment by the Stokes mortars, rushed and secured the farm. They found a number of dugouts, which they bombed, and secured 22 prisoners. The farm was connected with Tool Trench, and they proceeded to bomb their way up it. It would appear, therefore, that the 2nd London Regt. held a small section of this trench farther to the north, if any at all.
We must now follow the 167th Brigade on the left. The two attacking battalions had been met with even worse machine-gun fire than the 169th Brigade. There was no news of them for a long time. It is clear that neither the 1st London Regt. nor the 7th Middlesex ever held any of Tool Trench, but a few gallant parties did undoubtedly overrun Tool, and, crossing a sunken road known as Stirrup Lane, reached Lanyard Trench, quite a short distance from the men of the London Rifle Brigade, who had lodged themselves in the pit near Rohart Factory.
