CHAPTER I
THE GERMAN RETREAT UPON THE ARRAS-SOISSONS FRONT

Hindenburg's retreat—The advance of the Fifth and Fourth Armies—Capture of Bapaume and Peronne—Atrocious devastation by the Germans—Capture of guns at Selency—Definition of the Hindenburg Line—General survey.

In the latter days of 1916 and the beginning of 1917, the British Army, which had in little more than two years expanded from seven divisions to over fifty, took over an increased line. The movement began about Christmas time, and early in the New Year Rawlinson's Fourth Army, side-stepping always to the south, had covered the whole of the French position occupied during the Somme fighting, had crossed the Somme, and had established its right flank at a point near Roye. The total front was increased to 120 miles, which may seem a small proportion as compared to the whole. In making such a comparison, however, one must bear in mind the difference in the effort of sustaining an army in one's own country and in a foreign land with all communications by water. The task of the British was continually made more difficult by the precarious nature of their connection with their base. Dulness of vision may be as dangerous to a nation as treason, and no enemies could have harmed the country more than those perfectly sincere and patriotic individuals who had for so long opposed the construction of a Channel tunnel.

The general disposition of the British forces after this prolongation to the south was as follows. Plumer's Second Army still held that post of danger and of honour which centred round the Ypres salient. South of Plumer, in the Armentières district, was the First Army, now commanded by General Horne, whose long service with the Fifteenth Corps during the Somme Battle had earned him this high promotion. Allenby's Third Army carried the line onwards to the south of Arras. From the point upon which the British line had hinged during the Somme operations Gough's Fifth Army took over the front, and this joined on to Rawlinson's Fourth Army near the old French position. From the north then the order of the armies was two, one, three, five, and four.

The winter was spent by both sides in licking their wounds after the recent severe fighting and in preparing for the greater fighting to come. These preparations upon the part of the British consisted in the addition to the army of a number of fresh divisions, and the rebuilding of those divisions, fifty-two in number, which had taken part in the Somme fighting, most of them more than once. As the average loss in these divisions was very heavy indeed, the task of reconstructing them was no light one. None the less before the campaign re-opened, though the interval was a short three months, the greater part of the battalions were once again at full strength, while the guns and munitions were very greatly increased. A considerable addition to the strength of the army was effected by the civilian railway advisers, under Sir Eric Geddes, who by the simple expedient of pulling up their own lines at home, and relaying them in France, enormously improved the communications of the army.

In the case of the Germans their army changes took the form of a considerable new levy from those classes which had been previously judged to be unfit, and a general comb-out of every source from which men could be extracted. A new law rendered every citizen liable to national service in a civilian capacity, and so released a number of men from the mines and the factories. They also increased the numbers of their divisions by the doubtful expedient of reducing the brigades, so that the divisions were shorn of a third of their strength. The battalions thus obtained were formed into new divisions. In this way it was calculated that a reserve force had been created which would be suddenly thrown in on one or the other front with dramatic effect. Some such plan may have been in contemplation, but as a matter of fact the course of events was such that the German generals required every man and more for their own immediate needs during the whole of the year.

It has been shown in the narrative of 1916 how the British had ended the campaign of that year by the brilliant little victory of Beaumont Hamel, which gave them not merely 7000 prisoners, but command of both sides of the Valley of the Ancre. This victory had been the sequel to the capture of the Thiepval Ridge, and this again had depended upon the general success of the Somme operations, so that the turn of events which led to such considerable results always traces back to the tragic and glorious 1st of July. It was clear that whenever the weather permitted the resumption of hostilities, Sir Douglas Haig was in so commanding a position at this point that he was perfectly certain to drive the enemy out of the salient which they held to the north of Beaumont Hamel. The result showed that this expectation was well founded, but no one could have foreseen how considerable was the retreat which would be forced upon the enemy—a retreat which gave away for nothing the ground which cost Hindenburg so much to regain in the following year.

Although the whole line from the sea to the Somme was a scene of activity during the winter, and though hardly a day, or rather a night, went by that some stealthy party did not cross No-Man's-Land to capture and to destroy, still for the purposes of this narrative the three northern armies may be entirely ignored in the succeeding operations since they had no occasion to alter their lines. We shall fix our attention in the first instance upon Gough's Army in the district of the Ancre, and afterwards upon Rawlinson's which was drawn into the operations. Gough's Army consisted, at the beginning of the year, of three corps, the Fifth (E. A. Fanshawe) to the left covering the ground to the north of the Ancre, the Second Corps (Jacob) immediately south of the river, and the First Australian Corps (Birdwood) extending to the junction with Rawlinson's Army, and covering the greater part of the old British line upon the Somme. It was upon the Fifth and the Second Corps that the immediate operations which opened the campaign were to devolve.
