The instructions for the 167th Brigade are practically embodied in the following paragraphs:
“One company 167th Brigade will be placed at the disposal of the Brigadier-General commanding 169th Brigade, to hold sectors Y49 and Y50.
Seven officers and 200 men of the 167th Brigade will be detailed for the control of smoke, and will be under the orders of the Divisional Gas Officer. Approximately 1,200 men will be required for work under the C.R.E. on communication trenches across No Man’s Land and for carrying parties.”
Practice attacks, based on these instructions, were carried out by the brigades in reserve.
We have written of the constructive preparations which were going on all along the line of proposed attack. These preparations were continued until the last moment. But meanwhile another element was introduced—that of destructive preparation. It is scarcely necessary to point out that neither form of preparation could be concealed from the enemy. The Germans knew as well as we did where we would attack.
The Gommecourt sector to be attacked was held by the German 169th and 170th Regiments, with about 1-1/2 battalions on the front line, 1 battalion in support, 2 battalions in reserve in Bucquoy, and 2 companies at Ablainzeville. Their artillery consisted of 5 batteries of heavy artillery and 12 batteries of field artillery. These batteries were divided into three groups at Quesnoy Farm, on the left of the British position, Biez Wood and Puisieux. There was a further group of guns near Adinfer Wood which could assist in the defence.
The 56th Divisional Artillery, together with the heavy VII Corps guns, had now to prepare for the infantry assault by smashing up not only the wire and trench system, but billets and gun positions behind the German lines as well. As regards villages, most attention was given to Bucquoy, Essart, Ablainzeville, and Achiet-le-Grand.
Three groups of artillery were formed—a northern group, under Lieut.-Col. Southam, a southern group, under Lieut.-Col. Macdowell, and a wire-cutting group under Lieut.-Col. Prechtel. The northern and southern groups were under the orders of the Corps, and consisted of:
Northern Group
3 batteries of 18-pounders (until zero day, then 4 batteries).
