Each Brigade of the Division now became split up and battalions and companies were scattered far afield on one or other of the necessary works, of which a few have been enumerated above. On the 28th the 2/4th Londons moved further back from the line to Grenas (on the Doullens-Arras Road) leaving behind it two companies, A and C, which were attached to VII Corps troops (C Company joining the 56th Division) for road repairing at Wailly and Arras respectively. At the end of the month the Division, now attached to XIX Corps, was concentrated, with the exception of the detachments referred to, in the area of Frohen-le-Grand, between Doullens and Auxi-le-Château, and on the 1st April the 2/4th Battalion, less A and C Companies, marched to fresh billets in Bonnières, continuing their route the following day to Vitz Villeroy, some four miles west of Auxi-le-Château. From the beginning of March the Battalion had experienced continual rough handling, not only from enemy machine-gun and shell fire, but also from the remarkable amount of marching and counter-marching and exposure to the elements which the pursuit of the Germans had entailed. It must also be borne in mind that they had a month previously been raw troops of whom practically none had been under fire. The writer is, therefore, with all the more pleasure able to testify to the excellent bearing and strict march discipline of the Battalion as it swung through Auxi-le-Château on the 2nd April. But if the 2/4th Battalion expected rest after its labours it was soon to learn how illusive rest can be in modern war, for the next day it returned to Auxi and embussed to Beaumetz-les-Loges in the Arras area, when it once more took the road and marched to Boiry-St Martin. Accommodation here was provided for Headquarters and B Company in old German dugouts, while D Company contented itself with temporary and hastily constructed shelters in the village. A week of hard work in laying new track on the Arras-Albert Railway followed, and on the 12th the Battalion, having been rejoined by A and C Companies, moved to Pommier and thence to Achiet-le-Grand, where the remainder of the 173rd, now under command of Brig.-Gen. Freyberg, V.C., D.S.O., was concentrated. The Division was now in the Fifth Army area (Gough) and attached to the V Corps. The remainder of April, with the exception of short spells of training, was entirely devoted to working parties, the principal tasks entrusted to the 2/4th Londons being the formation of a large R.E. dump at Achiet-le-Grand, the construction of a light railway at Ervillers and the repair of the Ervillers-St Leger Road. During the period under review the Battalion received one or two small reinforcements of N.C.O.'s and men, and also the following officers: 18th March--2/Lieuts. G. H. Hetley, C. A. Clarke, S. M. Williams and G. E. Lester, and 2/Lieut. Acason (18th Londons). 27th April--2/Lieut. S. A. Seys (15th Londons).
