CHAPTER VI
THE THIRD BATTLE OF YPRES
July 31, 1917
Attack of July 31—Advance of the Guards—Of the Welsh—Capture of Pilkem—Capture of St. Julien by Thirty-ninth Division—Advance of Fifty-fifth Division—Advance of Jacob's Second Corps—General results.
It had been accepted as an axiom at this stage of the war that no great operation could be in the nature of a surprise—an axiom which, like most other axioms, was shown later in the year to have some startling exceptions. To pack the base of the historic Ypres salient with guns, and to assemble within and behind its trenches the storming troops for a great advance was, however, an operation which could not possibly be concealed. British aircraft might have an ascendency in observation, but that did not prevent the German fliers from being both daring and skilful. All camouflage, therefore, was thrown aside, and throughout the month of July Sir Douglas Haig openly assembled his forces for the widening or destruction of the iron bands which had so long constricted us in this northern area. The Fifth Army gathered for the venture, still commanded by Sir Hubert Gough, the victor of Thiepval. On his left, opposite Bixschoote, on the edge of the inundations, was a French army under General Antoine, a genial giant who impresses those who meet him as a mixture of Porthos and d'Artagnan. The general rôle of the French Army was to cover the British from counter-attack from the north, especially from Houthulst Forest, in the depths of which great reserves might lurk, for it covers no less than 600 acres. Upon the right, and engaged in a subsidiary degree in the operations, was the Second Army, under Sir Herbert Plumer, fresh from the triumph of Messines.
The direction of this new attack against the ridges of Flanders was the logical sequence from the preceding operations of the year. The high ground of the Ancre had been taken late in 1916. The high ground of Vimy fell into British hands in April. In June the Germans had been driven in one strenuous day from the high ground of Messines. The whole line of ridges from end to end was in British hands save only those which girt in Ypres and dominated it from the north and north-east. It is true that these so-called ridges were often little more than undulations, but they meant firmer ground, artillery observation, self-concealment, and everything which makes for military advantage. For these reasons Sir Douglas Haig turned his strength now in that direction. After his successive advances he might say with Wellington: "Knowing well that if we laid our bloody hands upon a town it was fated to fall." The men who took Ciudad Rodrigo or stormed the dreadful breach of Badajos could teach nothing in hardihood and contempt of death to those who carried Guillemont or Ovillers.
In attacking a salient like that of Ypres and in endeavouring to flatten it out, it is obvious that the efforts must be made at the sides rather than in the centre, since success in the latter case would simply mean a larger salient. Of the two sides of the salient the success of Messines had already relieved the pressure in the south, and this area was clearly less important than the north, since it was farther from the sea. It was evident that any considerable success upon the northern side would advance the British line towards Bruges, and an occupation of Bruges would surely mean the abandonment by Germany of the Flemish coast. For these reasons the effort of the British was chiefly directed towards the north-east, a tract of ground which was difficult when dry, but which became grotesque in its difficulties when it rained and the small low-lying streams or "beeks" which meandered through it spread out into broad marshy bottoms. These all-pervading morasses, when ploughed up with innumerable shell-holes, were destined to form an almost insuperable military obstacle. In attacking at such a point Sir Douglas could only hope that the weather would abide as a neutral, but as a fact, now as so often before, its action was bitterly hostile. Up to the very day of the advance it smiled deceitfully only to break into a month of rain from the very hour of the attack. If Berlin needs one more monument in her meretricious "Sieges-Alee," she may well erect one to the weather, which has saved her cause as surely as the geese of old saved Rome.
So notorious were the British preparations, culminating in the usual terrific bombardment, that the approaching conflict was discussed in the German papers weeks before it occurred. Their preparations had been gigantic, and took a new form which called for corresponding ingenuity upon the side of the stormers if it was to be successfully countered. The continuous trench had, save in the old system, been discarded as offering too evident a mark for the shattering guns. The ground was held by numerous disconnected trenches, and strong points arranged in depth rather than in breadth, so that the whole front should form one shock-absorber which would yield at first, but must at the last bring any pressure to a stand. Scattered thickly among these small posts there were concrete forts, not unlike the Martello towers of our ancestors, but sunk deeply into the ground, so as to present a small mark to gun-fire. These forts were made of cement and iron with walls so enormously thick that a direct hit from anything less than a six-inch gun could not possibly harm them. The garrisons of each were composed of twenty or thirty men, with two or three machine-guns. There was usually no visible opening, the entrance being approached by a tunnel, and the windows mere slits which gave a broad traverse for a machine-gun. They were contrivances which might well hold up an army, and it was a fine example of British adaptability as well as courage that they were able to make progress against them. The days of the gallant bull-headed rush were over, and the soldiers had learned in a cruel school that the fighting man must be wary as well as brave.
At four o'clock in the morning, in the first grey light of a rainy morning, under a canopy of grey sweeping clouds, and in a fog-girt landscape of bedraggled fields and brown patches of mire, the French and British infantry sprang forward with splendid alacrity upon this dangerous venture which should culminate in taking the last dominant ridge upon the British front from those who had held them so long.
The French attacked upon the extreme left of the line, and had an extremely difficult task, which they accomplished with a dash and spirit which won the unstinted admiration of their British comrades. In front of them was the canal, but they had succeeded in throwing across some troops in the days before the battle. It was fitting that they should advance the line in this sector, for they were starting from the very spot to which their comrades had been pushed in the poison-gas battle of April 22, 1915, more than two years before. The ground in front of them was very marshy, and as a background to the German position loomed the great forest of Houthulst, which was known to be a strong gun position and place of arms. It was subjected, however, to such a shattering bombardment that it was nearly silent when the attack advanced, and the French poilus, pushing rapidly on from point to point, seized the village of Steenstraate, and finally the larger village of Bixschoote, establishing their line well to the north of that point. It was a most valorous advance, and if no detail can be given of it save this passing mention, it is because it belongs to that weighty and wonderful volume which shall record the glorious military deeds of France, a volume which can only be written with proper appreciation and knowledge by a French pen.
The British line of battle was formed by five corps, the Fourteenth (Cavan) to the north, the Eighteenth (Maxse) upon its right, the Nineteenth (Watts) upon the right of that, the Second (Jacob) came next, and then upon the southern edge of the area, and hardly engaged in the main fighting, was the Tenth (Morland). Each corps had two divisions in the line and two in reserve. We will take each in turn, starting from the north. It should be noted that the four first corps made up Gough's Fifth Army, and that the Tenth Corps was the only part of Plumer's Army to be engaged.
