The attack of the 46th Division was to be directed against the German trenches West of Gommecourt, immediately opposite the village of Foncquevillers. The German trench line here, forming the Gommecourt salient, was the most Westerly point that they ever held as a permanent line. The general object of the attack was to cut off this salient. The 56th Division were to attack on the South, and join hands with our Division East of the village of Gommecourt, and so establish the left flank of the whole Somme attack.
All the efforts of the troops of our Division who were not actually holding the line, were concentrated on preparing the Divisional front for the attack. The chief work that we were concerned with, was the digging out of old communication trenches from Foncquevillers to the front line, a distance of about 700 yards. There were something like ten or a dozen of these, several of which were named after our Division. The principal were "Stafford Avenue," "Lincoln Lane," "Leicester Street," "Nottingham Street," "Derby Dyke," "Roberts Avenue," "Rotten Row," "Regent Street," "Raymond Avenue," and "Crawlboys Lane." All these had to be dug out about two feet below their existing level, making them about seven feet deep, and boarded with trench grids from end to end, which entailed an enormous amount of work. In addition, the front line had to be cleared of the barbed wire, with which the unoccupied portions had been filled, support and reserve trenches had to be prepared for the supporting troops in the attack, forward or "jumping-off" trenches to be dug at the last moment, for the assaulting troops to attack from, "Russian saps" to be dug out into No Man's Land to form communication trenches, by knocking in the thin covering of earth left to hide them, dug-outs to be made for forward Battalion Headquarters, and several miles of narrow cable trench to be dug about six feet deep for the protection of telephone wires from forward Headquarters back to Brigade, Division and Artillery Headquarters. In addition to all this navvying work, large quantities of stores had to be carried up to forward dumps in the trenches, ready for taking forward if the attack succeeded, shelters had to be made at various points in side trenches, convenient to get at from communication trenches, for storing large quantities of bombs of all kinds, small arm ammunition, iron rations, water, picks, shovels, sandbags, and other Royal Engineers' material likely to be required to consolidate the ground we hoped to win in the attack. The transport of all these stores, and of all the necessary Royal Engineers' material, and the work entailed in all these preparations was colossal, and our first real experience of anything of the kind. It is probable that at this time the mass and variety of material required in an attack, reached a degree of complication never equalled either before or after. The German comment on this contained in the diary already mentioned is of interest. "It must be acknowledged," it states, "that the equipment and preparation of the English attack were magnificent. The assaulting troops were amply provided with numerous machine guns, Lewis guns, trench mortars, and storming-ladders. The Officers were provided with excellent maps, which shewed every German trench system actually named and gave every detail of our positions. The sketches had been brought up to date with all our latest work, and the sectors of attack were shewn on a very large scale. Special sketches shewing the objectives of the different units, also aeroplane photographs were found amongst the captured documents."
