Upon September 15 the London Division went forward with the whole line at 6.20 in the morning, the 167th Brigade on the left, the 169th upon the right. The original direction of advance had been north and south, but it soon became almost from west to east as the division, pivoting upon Leuze Wood, swung round to attack Bouleaux Wood to the north of it, and to hold a defensive flank for the whole army. Their front was a very narrow one to allow for the fact that their essential work was lateral.
The 167th Brigade fought its way bravely into Bouleaux Wood, where they endured the usual horrors of this forest fighting, which came especially upon the 7th Middlesex battalion, who lost 400 men, chiefly from the fire of unseen machine-guns. There was a very heavy barrage between Ginchy and Bouleaux Wood, so that all reserves and supports endured heavy losses before they could get up. By mid-day the 1st London and the 8th were involved in the wood and some progress was being made, while the 2nd London of the 169th Brigade had taken and consolidated a trench near the Sunken Road, but a further attack upon a second trench to the east of Leuze Wood, two days later, was a failure. On this same day, September 18, the 168th Brigade relieved the 167th in Bouleaux Wood, while the whole division, like one blade of a scissors, edged its way eastwards towards Combles to meet the French Second Division, who were closing in from the other side. Already rumours were current that the Germans were evacuating this important little town, but many very active German trenches and strong points still lay all round it, through which the Allies, from either side, were endeavouring to force their way. On the night of September 18-19, the 5th Cheshires, pioneer battalion of the division, constructed a long trench parallel to Bouleaux Wood, which formed a defensive flank for the operations. The whole of this wood had now been cleared with the exception of the extreme northern corner. Here we may leave the Fifty-sixth Division, for the fall of Combles will fit in more properly to our next survey, when we shall have once again to go down the whole line from left to right and to show one more stage in the advance.
This Battle of Flers may be said to mark an epoch in military history on account of the use of the so-called tank, an instrument which had no vital effect upon the course of the fight, but which was obviously capable of being much enlarged, and of being made in every way more formidable. It had been a common criticism up to this date that our military equipment had always been an imitation, very belated, of that of our enemy. Now at last Great Britain, warming to the War, was giving her inventive and manufacturing as well as her military talents full scope—and the tank was the first-born of her fancy. It is a matter of history that Britain has been the inventor of processes and Germany the adapter of them, so that we had a valuable asset in that direction could we break through our bonds of red tape and get without hindrance from the thinker in his study to the fighter in the trench. Those who have had the experience of discussing any military problem in the Press, and have found by the next post fifty letters from men of all ranks and professions, presenting solutions for it, can best understand how active is the inventive brain of the country. In this instance, Mr. Winston Churchill is said, during his tenure of office, to have first conceived the idea of the tanks, but the actual details were worked out by a number of men. Especially they are owing to Colonel Stern, a civilian before the War, who used his knowledge of motor manufacture and his great organising ability to put the construction through in the shortest time, to Commander d'Eyncourt of the Navy, and to Colonel Swinton, R.E., who looked after the crews and equipment. On an average six of these engines, strange modern resuscitations of the war-chariots of our ancestors, were allotted to each division. The whole affair was frankly experimental, and many got into trouble through the breakdown of machinery, the limits of carrying capacity, and the slipping of the caterpillar driving-bands at the sides. Their pace, too, was against them, as they could only go twenty yards per minute as against the fifty of the infantry. Hence they had to be sent ahead down lanes in the barrage, with the result that the element of surprise was lessened. Their vision also was very defective, and they were bad neighbours, as they drew fire. The result was a very mixed report from various Divisional Commanders, some of whom swore by, and others at them. The net result, however, was summed up by the words of commendation from General Haig in his despatch, and there were some cases, as at Flers itself, where the work done was simply invaluable, and the machine-guns were nosed out and rooted up before they could do any damage. The adventures of individual tanks could, and no doubt will, fill a volume to themselves, some of them, either in ignorance or recklessness, wandering deep into the enemy's lines, and amazing rearward batteries by their sudden uncouth appearance. Several were destroyed, but none actually fell into the German hands. Enough was done to show their possibilities, and also to prove that the Navy and the Flying Service had not sufficed to exhaust our amazing supply of high-spirited youths ready to undertake the most nerve-shaking tasks so long as a touch of sport gave them a flavour. The very names of these land cruisers, Crême de Menthe and the like, showed the joyous, debonair spirit in which their crews faced the unknown dangers of their new calling.
Summing up the events of September 15, it was without any doubt the greatest British victory, though not the most important, which had been gained up to date in the War. July 1 was the most important, and all subsequent ones arose from it, since it was then that the Chinese Wall of Germany was breached. July 14 was also a considerable victory, but it was only a portion of the line which was attacked, and that portion was partly regained for a time by the German counter-attacks. The battle of September 15, however, was on as huge a scale as that of July 1, but was devoid of those long stretches of untaken trench which made us pay so heavy a price for our victory. From the Pozières Ridge upon the left to Bouleaux Wood upon the right twelve divisions moved forward to victory, and, save in the small section of the Quadrilateral, everything gave way at once to that majestic advance. The ultimate objectives had been carefully defined, for the Battle of Loos had taught us that the infantry must not outrun the guns, but this pre-ordained limit was attained at almost every spot. Martinpuich, High Wood, Flers, Delville, and Leuze Wood, all passed permanently within the British lines, and the trophies of victory amounted to 5000 prisoners and a dozen guns. At this stage no less than 21,000 prisoners had been taken by the British and 34,000 by the French since the great series of battles was commenced upon July 1.
CHAPTER XI
THE GAINING OF THE THIEPVAL RIDGE
Assault on Thiepval by Eighteenth Division—Heavy fighting—Co-operation of Eleventh Division—Fall of Thiepval—Fall of Schwaben Redoubt—Taking of Stuff Redoubt—Important gains on the Ridge.
Having treated the successful advance made by Rawlinson's Fourth Army upon September 15, it would be well before continuing the narrative of their further efforts to return to Gough's Army upon the north, the right Canadian wing of which had captured Courcelette, but which was occupied in the main with the advance upon the Thiepval Ridge.
The actual capture of Thiepval was an operation of such importance that it must be treated in some detail. The village, or rather the position, was a thorn in the side of the British, as it lay with its veteran garrison of Würtembergers, girdled round and flanked by formidable systems of trenches upon the extreme left of their line. Just above Thiepval was a long slope ending in a marked ridge, which was topped by the Schwaben Redoubt. Both armies recognised the extreme importance of this position, since its capture would mean a fire-command over all the German positions to the north of the Ancre, while without it the British could never reap the full result of their success in breaking the line upon July 1. For this reason, instructions had been given to the picked German troops who held it to resist at all costs, even to the death. They had massed at least four hundred guns in order to beat down every assault. Yet the attempt must be made, and it was assigned to Jacob's Second Corps, the actual Divisions engaged being the Eighteenth and the Eleventh, both of them units recruited in the South of England. The latter was distinguished as the first English Division of the New Armies, while the former had already gained great distinction in the early days of the Somme battle when they captured Trones Wood. They were supported in their difficult venture by a considerable concentration of artillery, which included the guns of the Twenty-fifth and Forty-ninth Divisions as well as their own. Jacob, their Corps leader, was an officer who had risen from the command of an Anglo-Indian Brigade to that of a Corps within two years. The whole operation, like all others in this region, was under the direction of Sir Hubert Gough.
