THE TERRAIN

The terrain over which the plan of the allies was to be tested must next be grasped if we are to understand the causes which led to its ultimate failure.

That terrain is most conveniently described as an oblong standing up lengthways north and south, and corresponding to the sketch map overleaf. That oblong has a base of twenty miles from east to west, a length from north to south of thirty-five.

These dimensions are sufficient to show upon what a scale the great plan of the allies for cutting off Souham at Courtrai was designed.

At its south-eastern corner the reader will perceive the town of St Amand, the furthest point south from which the combined movements of the allies began; while somewhat to the left of its top or northern edge, at the point marked “A,” the northern-most body connected with that plan, the body commanded by Clerfayt, was posted at the origin of the movement.

The object of the whole convergence from the Scheldt on one hand, and from Clerfayt’s northern position upon the other, being to cut off the French forces which lay at and south of Courtrai from Lille, and the main line of the French army, it is evident that the actual fighting and the chances of success or disaster would take place within a smaller interior oblong, which I have also marked upon the sketch map. This smaller or interior oblong measures about sixteen miles at its base by about twenty-five miles in length, and includes all the significant points of the action.

The points marked 1, 2, 3, 4, and 5 respectively are the points at which the five columns advancing from the Scheldt valley northward were to find themselves before dawn on the morning of Saturday the 17th of May. We are already acquainted with them. They are Warcoing, Bailleul, Templeuve, Froidmont, and Pont-a-Marcq respectively; while the point marked 6 is Wervicq, from which Clerfayt was to start simultaneously with the five southern columns with the object of meeting his fellows round Tourcoing.

The town of Courtrai will be perceived to lie in the north-eastern angle of this inner oblong, the town of Lille rather below the middle of its western side. In all the country round Courtrai, and especially to the south of it, within the triangle X Y Z, lay the mass of Souham’s command of 40,000 men. There were many posts, of course, scattered outside that triangle, and connecting Courtrai with Lille; but the links were weak, and the main force was where I have indicated it to be.

A large body of French troops being encamped just under the walls of Lille at B (by which letter I mark Sainghin camp), and that fortress also possessing a garrison, the plan of cutting both these off from the 40,000 French that lay in the country near Courtrai involved getting the main part of the allies up from these points of departure on the south, and Clerfayt’s body down from its point of departure on the north to meet upon the line drawn between Lille and Courtrai. Upon this line (which also roughly corresponds to the only main road between the two cities) may be perceived, lying nearer Lille than the centre of such line, the small town of Tourcoing and the village of Mouveaux. It was upon these two points that four of the five southern columns were to converge northward, the second and third column reaching them first, the fourth and fifth marching up from the left in aid; and it was also, of course, upon these two points that Clerfayt was to march southward from the post at Wervicq, that had been given him as his point of departure before dawn upon that Saturday morning. If everything went perfectly, the great mass of the allied army should have found itself, by noon of Saturday the 17th, as I have said, astraddle of the Lille-Courtrai road, and effectively cutting off the French troops to the north.

What was the nature of the wide countryside over which these various movements were to take place?

It was part of that great plain of Flanders which stretches from the River Scheldt almost unbroken to the Straits of Dover and the North Sea. In the whole of the great oblong represented by my sketch map there is hardly a point 150 feet above the water level of the main river valleys, while the great mass of that territory is diversified by no more than very broad and very shallow rolls of land, the crests of which are sometimes and exceptionally as much as fifty feet above the troughs, but the greater part thirty, twenty, or even less. Here and there an isolated hummock shows upon the landscape, but the general impression of one who walks across from the valley of the Lys to that of the Scheldt is of a flat, monotonous land in which one retains no memory of ascent or descent, and in which the eye but rarely perceives, and that only from specially chosen points, any wide horizon.

To-day the greater part of this country suffers from the curse of industrialism and repeats of course, with far less degradation the terrible aspect of our own manufacturing towns. Roubaix and Tourcoing in particular are huge straggling agglomérations of cotton-spinners and their hands. A mass of railways and tramways cut the countryside, and the evil presence of coal-smoke mars it everywhere: at least within the region of Lille, Tourcoing, and Roubaix.

In May 1794, though a considerable industry had begun to grow up in Lille itself, the wide, open countryside round the town was entirely agricultural. Much of it was what soldiers call “blind” country: that is, it was cut up into fields with numerous hedges; there were long farm walls and a great number of small watercourses fringed with trees. But, on the other hand, there was very little wood. Moreover, though there were few places from which one could overlook any considerable view, the “blindness” of the field, as a whole, has been much exaggerated in the attempt to excuse or explain the disaster of which it was the theatre. The southern part of it is open enough, and so is the north-eastern portion, in which the first column operated. Of the soil no particular mention is needed; most of the great roads were paved; the weather had created no difficulty in the going, and the only trouble in this respect lay in the northern part, where Clerfayt’s command was condemned to advance over patches of loose and difficult sand, which made the road, or rather rare lanes, very heavy.

It will at once be perceived that, in view of the operations planned, one principal obstacle exists in the terrain, the River Lys. Few bridges crossed this stream, and for the purpose of turning the French position and coming across the Lys from the north to the neighbourhood of Mouveaux, there was in those days no bridge save the bridge at Wervicq (at the point marked 6 on the plan at the beginning of this section); but this difficulty we have seen to be lessened by the presence in Clerfayt’s command of a section of pontoons.

At first sight one might perceive no other considerable obstacle save the Lys to the general movement of the allied army. But when the peculiar course of the little River Marque is pointed out, and the nature of its stream described, the reader will perceive that it exercised some little effect upon the fortunes of the battle, and might have exercised a much greater one to the advantage of the British troops had not the Duke of York blundered in a fashion which will be later described.

In the first place, it should be noted that this little stream (it is no wider than a canal, will barely allow two barges to pass in its lower course, and will not float one to the southward of Lille) turns up quite close to Roubaix, and at the nearest point is not a mile from the market-place of that town.

Now the significance of such a conformation to the battlefield of Tourcoing lay in the fact that it was impossible for any considerable force to manoeuvre between the third column (which was marching upon Roubaix) and the Marque River. Had the Marque not existed, Kinsky, with the fourth column, would have been free to march parallel with York, just as York marched parallel with Otto, while the Arch-Duke with his fifth column, instead of having been given a rendezvous right down south at Pont-a-Marcq (the point marked 5 on my sketch), would have gone up the main road from St Amand to Lille, and have marched parallel with Kinsky, just as Kinsky would have marched parallel with York. In other words, the fourth and the fifth columns, instead of being ordered along the dotted lines marked upon my sketch (the elbows in which lines correspond to the crossing places of the Marque), would have proceeded along the uninterrupted arrow lines which I have put by the side of them.

The Marque made all the difference. It compelled the fifth column to take its roundabout road, and the fourth, detained by the delay of the fifth, was held, as we shall see in what follows, for a whole day at one of the crossings of the river.

The little stream has a deep and muddy bottom, and the fields upon its banks are occasionally marshy. This feature has been exaggerated, as have the other features I have mentioned, in order to explain or excuse the defeat, but, at any rate, it prevented the use of crossing places other than bridges. The Marque has no true fords, and there is no taking an army across it, narrow as it is, save by the few bridges which then existed. These bridges I have marked upon the sketch.

So far as the terrain is concerned, then, what we have to consider is country, flat, but containing low defensive positions, largely cut up, especially between the Scheldt and Roubaix, by hedges and walls, though more open elsewhere, and particularly open towards the north: a serious obstacle to the advance of one body in the shape of the River Lys; and another obstacle, irritating rather than formidable in character, but sufficient both by its course and its marshy soil to complicate the advance, namely, the little River Marque.

As to the weather, it was misty but fine. The nights in bivouac were passed without too much discomfort, and the only physical condition which oppressed portions of the allied army consisted in the error of its commanders, and proceeded from fatigue.
