At any rate, it was upon the morrow, the 11th, that the English Prince sent word to Clerfayt that he intended to submit to the Emperor, who was the ultimate authority upon the side of the allies, a plan for the general and decisive action he desired to bring about. On the next day, the 12th, a Monday, the Duke of York wrote to Clerfayt that he hoped, “on the day after the morrow” (that is, upon the Wednesday, the 14th), “to take a decisive movement against the enemy.” And we may presume that the Duke had communicated to the Emperor the nature of his plan. For on the 13th, the Tuesday, the Emperor was in possession of it, and his orders, sent out upon that day, set out the plan in detail.[1] That plan was as follows:—
Clerfayt, with his force, which was rather less than 20,000 all told, was to march south from Thielt, his headquarters for the moment, and advance upon the little town of Wervicq upon the River Lys. Here there was a bridge, and Clerfayt was also in possession of pontoons wherewith to pass the stream. Meanwhile, the southern mass of the allies was to concentrate upon the Scheldt in the following manner:
The few thousand Hanoverians, under Bussche, were to take up their position at Warcoing, just upon and across that river. Two miles further south, Otto, with a larger Austrian force accompanied by certain English cavalry (the numbers will follow), was to concentrate at Bailleul.
The Duke of York’s own large force, which had been at Tournai for over a week, was to go forward a little and concentrate at Templeuve. Five miles to the south of Templeuve, at Froidmont, a column, somewhat larger than the Duke of York’s, under Kinsky, was to concentrate.
There were thus to be concentrated upon the south of the French wedge four separate bodies under orders to advance northward together.
The first, under Bussche, was only about 4000 strong, the Hanoverians and Prussians; the second, under Otto, from about 10,000 strong; the third, under the Duke of York, of much the same strength, or a little less; and the fourth, under Kinsky, some 11,000.
These four numbered nearly, or quite, 35,000 men, less than the “nearly 40,000” at which certain French historians have estimated their strength.
To these four columns (which I will beg the reader to remember by their numbers of first, second, third, and fourth, as well as by the names of their commanders, Bussche, Otto, York, and Kinsky) a fifth must be added, the appreciation of whose movements and failure is the whole explanation of the coming battle.
The fifth column was a body of no less than 16,000 men coming from the main Austrian body far south, and ordered to be at St Amand upon the Scheldt somewhat before the concentration of the other four columns, and to advance from St Amand to Pont-à-Marcq. Upon reaching Pont-à-Marcq this fifth column would be in line with the other four at Warcoing, Bailleul, Templeuve, and Froidmont, and ready to take its part in the great forward movement towards the north.
In order to appreciate the way in which the issue was bound to depend upon this fifth column, I must now detail the orders given to all six, the five columns in the valley of the Scheldt, and the sixth body, under Clerfayt, north of the Lys; for it is these orders which constitute the soul of the plan.
