At that moment our line, on the Somme side, ran from Lens just behind Oppy, through Rœux, five miles east of Arras, south to Bullecourt, south-easterly towards Boursies, round the Flesquières-Ribecourt Salient that Cambrai fight had won for us, curved back between Gonnelieu and Gouzeaucourt, and thence dropped, skirting St. Quentin and the valley of the Oise, to the junction with the French at Barisis, south of that river. This length, of close on seventy miles, was held, from Barisis to Gouzeaucourt, by Byng’s Third Army, and from Gouzeaucourt to Gavrelle, by Gough’s Fifth Army. North of this, the First Army took on. The working and reserve strength of the Third and Fifth Armies at the opening of 1918 was twenty-nine infantry and three cavalry divisions. So far as our arms were concerned, everything on the French and Belgian fronts was at a standstill. The Somme had cost very heavily throughout the year, and there was, or was said to be, a scarcity of men. The situation appears to have been met by reducing the number of battalions in the brigades from four to three apiece. This released the odd battalions to make what, on paper, and in the journals, looked like additional brigades, but threw extra work, which nowhere appeared as news, on the whole of the army administration in the field. Sir Douglas Haig’s despatches refer guardedly to the reorganization, which he hints “to some extent affected” the fighting efficiency of the units concerned. The sentiments of commanders more directly concerned were, perhaps, less publishable; for it rarely improves an old army in the field to lace it at the last moment, before a general attack, with new brigades composed of battalions suddenly disassociated from the units with whom they have been working. But thus was created the Fourth Guards Brigade, by lopping off the 4th Grenadiers, the 2nd Irish Guards, and the 3rd Coldstream from their respective brigades, and attaching them to the Thirty-first Division. Further, it was necessary for the British armies to take over another stretch of nearly thirty miles from the French on the right--approximately from Barisis to Vendhuille on the Oise--and this brought the British front up to one hundred and twenty-five miles total length.
