The front of attack on which the British armies were to operate covered the whole of the above described line from Gommecourt to Curlu—a total of about 17 miles—while the French were to co-operate on a wide front immediately south of the River Somme.
The story of the struggle which, lasting from the beginning of July until the early part of November, gave us possession, first of the forward trench systems, then of the crest of the ridge, and finally of the whole plateau and parts of the further slopes, divides itself into phases, which can be dealt with in turn to such an extent as the record of the 1/4th Battalion is concerned with them. For the present we are concerned with the enormous preparations which preceded the opening of the struggle and of the first phase of the battle which began on the 1st July 1916.
Dealing with the preparations for the battle generally, an enormous amount of work was required in improving road and rail communications; in digging assembly trenches and dugouts, for use not only as shelters but also as aid posts and stores for ammunition for small arms and trench mortars; and in constructing many additional machine-gun and gun emplacements. The water supply for the assaulting troops presented a serious problem, and Sir Douglas Haig records in his Despatches that in this connection over a hundred pumping plants were installed and over 120 miles of water mains laid.
During most of the period in which this preliminary labour proceeded the troops were working under most trying weather conditions and frequently were harassed by heavy enemy fire.
The particular tasks for which the 168th Brigade, and in particular the 1/4th Londons, were called upon will be referred to in their places at greater length.
After remaining in training in the Frevent area for the latter half of March and the whole of April the 56th Division moved forward on the 3rd and 4th of May into the VII Corps area (D'Oyly Snow) and took over from the 46th Division a sector of the line in front of the village of Hébuterne and facing Gommecourt.
The line was occupied by the 167th Brigade, the 168th moving in reserve to Souastre, a small village some three miles west of the front trenches. The Battalion moved by march route from Beaufort on the 6th and arrived at Souastre after a ten mile march at 9 p.m.
Two or three days were occupied in training, and on the 11th May the Battalion began to supply working parties of considerable size. Of these, one of 200 all ranks was despatched to Pas and employed in felling and sawing trees to form props for gun pits and dugouts; and another of 250 all ranks went to the chalk quarries of Hénu, where they were given a task in digging road material. These working parties, the first of many weary tasks, constituted so far as the Battalion was concerned the first direct active preparations in the area of battle for the Somme offensive.
The Battalion's duty at Souastre lasted a fortnight. Work, however, did not take up the whole of the Battalion's time, and opportunity was found for a football match with the Kensingtons, which was played on the 12th May and resulted in a draw at one all. A few days later the Battalion entered representatives at the London Scottish sports at St. Amand, securing second and third places in the "open" 200 yards.
