But there was no sign of any such welcome sight. The dull rolling plain, with its occasional low crests falling towards the river, betrayed the presence of troops in more than one position to the north and west. But those troops were not moving: they were holding positions, or, if moving, were obviously doing so with the object of contesting the passage of the river. They were French troops, not Austrian, that thus showed distinctly in rare and insufficient numbers along the southern bank of the Lys, and indeed, as we know, Clerfayt, during the whole of that afternoon of the 17th, was painfully bringing up his delayed pontoons, and was, until it was far advanced, upon the wrong side of the river.
Otto maintained his position, hoped against hope that Clerfayt might yet force his way through before nightfall, and was still master of Tourcoing and the surrounding fields when darkness came.
(B) The Third Column under York
Meanwhile York, with his 10,000 half British and half Austro-Hessian, had marched with similar success but against greater obstacles parallel with Otto, and to his left, and had successively taken every point in his advance until he also had reached the goal which had been set before him.
Details of that fine piece of work deserve full mention.
Delayed somewhat by a mist in the dark hours before dawn, York’s command had marched north-westward up the road from Templeuve, where now runs the little tramway reaching the Belgian frontier.
The French troops in front of him, as much as those who had met Otto a mile or two off to the right, and Bussche still further off at Mouscron, were taken aback by the suddenness and the strength of the unexpected blow. They stood at Lannoy. York cannonaded that position, sent certain of the British Light Dragoons round to the left to turn it, and attacked it in front with the Brigade of Guards. The enemy did not stand, and the British forces poured through Lannoy and held it just as Otto in those same hours was pouring into and holding Leers and Wattrelos. Beyond Lannoy, a matter of two miles or so, and still on that same road, was the small town, now swollen to a great industrial city, called Roubaix. The Duke of York left a couple of battalions of his allied troops (Hessians) to hold Lannoy, and with the rest of the column pursued his march.
Roubaix offered far more serious resistance than Lannoy had done. The element of surprise was, of course, no longer present. The French forces were concentrating. The peril they were in of being cut off was by this time thoroughly seized at their headquarters, and the roll of land immediately before Roubaix was entrenched and held by a sufficient force well gunned. A strong resistance was offered to the British advance, but once more the Brigade of Guards broke down that resistance and the place was taken with the bayonet.
York’s next objective, and the goal to which his advance had been ordered, was Mouveaux. Mouveaux is a village standing upon a somewhat higher roll of land rather more than two miles from the centre of Roubaix, in continuation of the direction which York’s advance had hitherto pursued. From Mouveaux the eye could overlook the plain reaching to the Lys and to Wervicq, some seven odd miles away, a plain broken by one or two slight hummocks of which the least inconspicuous holds the village of Linselles. Mouveaux was the point to which Clerfayt was expected to advance from his side. It was on a level with Tourcoing, and lay, as Tourcoing did, precisely upon the line between Courtrai and Lille. To reach Mouveaux, therefore, and not to be content with the capture of Roubaix, was consistent with and necessary to the general plan of the allies. Moreover, as Otto with the second column had taken Tourcoing, it was necessary that the third column should proceed to Mouveaux, unless Otto’s left or southern flank was to remain exposed and in peril. One may say, in general, that until Mouveaux was occupied the chance of joining hands with Clerfayt (supposing that General to have kept to his time-table and to be across the Lys and marching up to meet the columns from the Scheldt) was in peril. Therefore, until one has learnt what was happening to the fourth and the fifth columns, it is difficult to understand why the Duke of York, after the difficult capture of Roubaix, desired to make that point the utmost limit of his advance and for the moment to proceed no further. Without anticipating the story of the fourth and fifth columns, it is enough to say that the Duke of York’s desire not to advance beyond Roubaix was sufficiently excused by the aspect of the country to the west and south upon his left.
Roubaix overlooks from a slight elevation the valley of the Marque. Lest the word “valley” be misleading, let me hasten to add that that stream here flows at the bottom of a very slight and very broad depression. But, at any rate, from Roubaix one overlooks that depression for some miles; one sees five miles distant the fortifications of Lille, and the intervening country is open enough to betray the presence of troops. Indeed, once Roubaix was captured, the English commander could see across those fields, a couple of hours’ march away, the tents of the great French camp at Sainghin under the walls of the fortress.
