When the last-noted draft joined, the Battalion was treated to the annoying spectacle of watching a further 100 men of the 2/4th Battalion marching by en route for the Kensingtons.

The day following arrival at Halloy being Sunday, a parade service was held, the first since the 14th May; and later in the day a further reinforcement, this time composed entirely of officers, reported to the Battalion from the disbanded 2/4th Battalion, as follows:

Capts. R. N. Arthur and H. G. Stanham, Lieuts. W. R. Botterill and W. A. Stark, and 2/Lieuts. H. W. Vernon, B. F. L. Yeoman, H. G. Hicklenton and N. W. Williams.

The two first-named officers had been mobilised with the 1/4th Battalion in August 1914, and were thus particularly welcome. The officers of this draft were distributed among the companies, and Capt. Arthur took over the duties of Works Officer as Major, an appointment he continued to fill until the 27th June, when he was evacuated to hospital seriously ill.

The 5th, 6th and 7th June were spent in training, of which the principal feature was a practice attack over trenches constructed to represent those opposite the sector of line which the Battalion had just left, in preparation, of course, for the coming battle. Following the last day's practice the Battalion was inspected by the Third Army commander, Sir Edmund Allenby, who was accompanied by Major-Gen. Hull and Brig.-Gen. Loch, and expressed himself satisfied with all that he had seen and also with what he had heard of the Battalion's behaviour during its recent tour of duty. A report of this kind may read curiously at first in view of the fact that the Battalion had been in France for eighteen months and had proved its steadiness in the line on many occasions: but remember that the 56th Division was brand new, and commanders so far did not know how their troops would shape in action. Praise from Allenby at this stage was therefore praise indeed.

The same day the Battalion was once more sent adrift from its own Brigade and became attached for duty to the 169th Brigade, though it retained its billets at Halloy, and the 168th Brigade took over W and Y sectors, Headquarters moving from Grenas to Sailly.

The Battalion now became responsible for the various works duties in the back area, relieving the L.R.B. in this monotonous task; and from this date onwards remained hard at work on various tasks until almost the eve of battle. B Company was despatched to Mondicourt, an important and vast R.E. dump on the Doullens-Arras Road, for work under the R.E.'s. The remaining companies were split up to supply parties for the daily work, the total numbers found each day being 8 officers and 350 other ranks, employed on such varied tasks as digging road material in Halloy quarries; carrying logs at Pas for gun emplacements; shifting and loading timber at Mondicourt; and working in the R.E. workshop at Pas. This programme was pushed forward without a break until the 12th June, the only intermission being an inspection on Sunday the 11th, of such remnants of the Battalion as were available, by Sir Charles Wakefield, then Lord Mayor of London, who was accompanied by Major-Gen. Hull and Col. Evelyn Wood, and addressed the troops.

On the 13th a further redistribution of Brigades took place, the 168th remaining in line but retaining W sector only; Y sector was handed over to the 169th Brigade; while the 167th moved back into reserve. This move placed the Brigades in the positions they were destined to occupy on the day of battle. The same day the 1/4th Londons moved forward, leaving Halloy at 5 p.m., and marching via Authie, St Leger and Coigneux to Bayencourt, where it was joined in billets by B Company from detachment at Mondicourt. A Company was pushed straight on to Hébuterne, when in spite of its long march and late arrival in billets it set to work on its share of the Brigade works programme at 5 a.m. on the 14th June.

The remaining companies were also set to work on the 14th in Hébuterne on parts of the Brigade scheme, working hours being nightly from 9 p.m. to 5 a.m. The parties were much split up, 280 being detailed to the 2/2nd Field Company R.E., 140 to the 5th Cheshires and 140 to the Brigade Signal Officer for digging cable trenches. The tasks were various, but were all directed in one way or another to the completion and repair of the new trench system and the necessary dugouts for the impending offensive. Night after night, for fourteen nights in succession, did the Battalion continue these stiff working parties. Each night there was a march of nearly three miles in each direction between billets and work, each night the Bosche was unpleasantly active with machine-guns, and nearly every night it rained steadily. That the Battalion carried out this depressing duty—for there is nothing with which the average infantryman gets more quickly "fed up" than continual working parties—with such efficiency and keenness is all the more to its credit. Conditions were not comfortable and the men were beginning to be tired; but they stuck to it well for they knew the urgency of the work and how much remained to be done in an impossibly short time.

On the 21st June the 167th Brigade took over the whole Divisional sector for six days in order to give a final rest to the 168th and 169th and to keep them as fresh as possible for battle. The 168th withdrew to its old rest billets at Halloy, but again the 1/4th Londons were left behind as works battalion, remaining in Hébuterne attached to the 167th Brigade and sticking to its works programme.
