and retaking of the same set of trenches near Hooge, in the extreme northern section of the line. Before giving some account of these events it would be well to interrupt the narrative for a time in order to describe that vast expansion of the British Army which was the most unexpected, as it was the most decisive, factor in the war. Without entering into the question of the huge muster of men within the island, and leaving out of consideration the forces engaged in the Near East, the Persian Gulf, and the various Colonial campaigns, an attempt will be made to show the reader the actual battle-line in France, with the order and composition of the troops, during the summer of 1915. The extreme left wing of the Allied Army consisted now, as before, of the Belgians and of a French corps, the right Moroccan Division of which was the {142} neighbour of the British Army. The British line had been extended northwards as far as the village of Boesinghe. If now the reader could for a moment imagine himself in an aeroplane, flying from north to south down the Imperial battle-line, he would see beneath him first Keir's Sixth Army Corps, which was composed of the Fourth Division (Wilson) and of the Sixth Division (Congreve). To the south of these lay the Forty-ninth West Riding Division of Territorials (Baldock). These three divisions, the Fourth, the Sixth, and the Forty-ninth, formed Keir's Sixth Army Corps, lying to the north of Hooge. Upon their right, in the neighbourhood of Hooge, holding the ground which had been the recent scene of such furious fighting, and was destined to be the most active section of the line in the immediate future, was Allenby's Fifth Corps. General Allenby had been taken from the command of the cavalry, which had passed to General Byng, and had filled Plumer's place when the latter took over Smith-Dorrien's Army at the end of April. Allenby's Corps consisted of the veteran Third Division (Haldane's) on the north. Then came, defending the lines of Hooge, the new Fourteenth Light Division (Couper). Upon its right was the Forty-sixth North Midland Division (Stuart-Wortley). These three divisions, the Third Regular, Fourteenth New, and Forty-sixth Territorial, made up the Fifth Corps. The Second Army Corps (Ferguson) lay to the south of Hooge. Their northern unit was the old Regular Fifth Division (Morland). To its south was a second Regular division--Bulfin's Twenty-eighth, of Ypres renown. On its right was the Fiftieth Northumbrian Division (Lindsay), consisting of those {143} three gallant Territorial brigades which had done so splendidly in the crisis of the gas battle.
