The continued German pressure at Verdun which had reached a high point in June called insistently for an immediate allied attack at the western end of the line. With a fine spirit of comradeship General Haig had placed himself and his armies at the absolute disposal of General Joffre, and was prepared to march them to Verdun, or anywhere else where he could best render assistance. The solid Joffre, strong and deliberate, was not disposed to allow the western offensive to be either weakened or launched prematurely on account of German attacks at the eastern frontier. He believed that Verdun could for the time look after herself, and the result showed the clearness of his vision. Meanwhile, he amassed a considerable French army, containing many of his best active troops, on either side of the Somme. General Foch was in command. They formed the right wing of the {34} great allied force about to make a big effort to break or shift the iron German line, which had been built up with two years of labour, until it represented a tangled vista of trenches, parapets, and redoubts mutually supporting and bristling with machine-guns and cannon, for many miles of depth. Never in the whole course of history have soldiers been confronted with such an obstacle. Yet from general to private, both in the French and in the British armies, there was universal joy that the long stagnant trench life should be at an end, and that the days of action, even if they should prove to be days of death, should at last have come. Our concern is with the British forces, and so they are here set forth as they stretched upon the left or north of their good allies. The southern end of the whole British line was held by the Fourth Army, commanded by General Rawlinson, an officer who has always been called upon when desperate work was afoot. His army consisted of five corps, each of which included from three to four divisions, so that his infantry numbered about 200,000 men, many of whom were veterans, so far as a man may live to be a veteran amid the slaughter of such a campaign. The Corps, counting from the junction with the French, were, the Thirteenth (Congreve), Fifteenth (Horne), Third (Pulteney), Tenth (Morland), and Eighth (Hunter-Weston). Their divisions, frontage, and the objectives will be discussed in the description of the battle itself. ------------------------------------------------------------------- {35} [Illustration: BRITISH BATTLE LINE July 1st 1916] ------------------------------------------------------------------- North of Rawlinson's Fourth Army, and touching it at the village of Hébuterne, was Allenby's Third Army, of which one single corps, the Seventh (Snow), was engaged in the battle. This added three {36} divisions, or about 30,000 infantry, to the numbers quoted above.
