The whole country behind this vast front was teeming with men and horses, with wagons and motor lorries. At night it was as though an army of gigantic ants were at work, stretched out in long lines, building and excavating, marching in solemn silent processions with grim, determined purpose in the slowness of their gait, and bowed down under loads of material. They passed and repassed in never-ending streams; the roads were congested with motor and wagon traffic; paths across the open country could be traced by the shadowy silhouettes of men in single file. And the horizon flickered with the flash of guns as with summer lightning, while shells passed overhead with a long-drawn, ghostly wail, or fell with a sharp swish and a crash. The line, that maze of foul mud-filled ditches constructed in a belt of shell-pounded and festering earth, was indicated at night by floating starlights rising irregularly as sparks, bursting into brilliancy, and remaining for a moment, suspended in the blackness of the sky like arc lamps, then dying once more to so many sparks before they fell to the ground.

Sometimes the nights would be quiet—that is to say, quiet except for occasional crashes at intervals of several minutes—although the constant flickering on the horizon would never cease; at others they would be “lively,” one might almost say there would be a sensation of hustle, so swift would be the wailing passage and so continuous the crash of bursting shells. This might last all through the night as an organised “shoot,” or would come suddenly, without warning, a swift artillery attack on roads, working parties, or

billets—what was afterwards known as “harassing fire” though it was in a more intense form—and shifting from one point to another, from front line to roads, from roads to billets, from billets to some spot where troops were suspected to be working. Or there would be a raid with an angry concentration of artillery from both sides.

And night after night the preparation for the “Big Push” went on.

The 56th Division, now trained and “shaken together,” arrived in the Hébuterne sector, on the right of the Gommecourt salient and towards the left of the front under preparation for the British effort. The 167th Brigade took over the front-line system held by the 145th Brigade, 48th Division, on the 4th May. The 168th Brigade marched from their billets in the Doullens area on the 6th, and the 169th Brigade followed on the 7th May. Divisional Headquarters were established at Hénu.

First blood was drawn for the division by the 167th Brigade on the 18th May. A German patrol attempted to bomb a sap held by the 3rd London Regt., and was beaten off with the loss of one officer and one N.C.O. killed. These proved to be of the 169th Infantry Regt., 52nd Division, one of the divisions of the XIV German Corps and a normal identification.

The system of holding the line was one of “grouping.” On the 22nd May Brig.-Gen. Coke, 169th Brigade, was in command of the line, which was held by two battalions of the 169th Brigade and two battalions of the 168th Brigade. In support was Brig.-Gen. Nugent, with his headquarters at

Souastre, having under his command his own four battalions and one of the 169th Brigade. Brig.-Gen. Loch, 168th Brigade, with his headquarters at Grenas, had two of his own battalions and one of the 169th Brigade.

Plans were now in preparation for a very remarkable achievement.
