But from what we know of the family to which the Duke of York belonged, it is exceedingly improbable that this younger son of George III. had, on this one occasion only, any lightning in his brain; and even if he did appreciate more or less the importance of rapid action, the Emperor did not appreciate it. He committed the two contradictory faults of delaying the movement and of asking too much marching of his men, and it was not until the morning of the Wednesday, May the 14th, that the bulk of the Austrian army, which still lay in the Valenciennes and Landrecies district, broke up for its northward march, to arrive at the rendezvous beyond the Scheldt, and to carry out the plan.[2] It was not until Thursday the 15th of May that the Emperor joined the Duke of York at Tournai, and very late upon the same day the Arch-Duke Charles had brought up the main body of the Austrian forces from the south to the town of St Amand. We shall see later what a grievous error it was to demand so violent an effort from the men of the Arch-Duke Charles' command. From Landrecies itself to St Amand is 30 miles as the crow flies; and though, of course, the mass of the troops which the Arch-Duke Charles had been thus commanded to bring up northward in such haste were most of them well on the right side of Landrecies when the order to advance reached them, yet the average march undertaken by his men in little more than twenty-four hours was a full twenty miles, and some of his units must have covered nearer thirty. I will not delay further on this point here; its full importance will appear when we come to talk of the action itself. The Arch-Duke Charles being only as far as St Amand on the evening of Thursday the 15th, and his rendezvous, that of the fifth column in the great plan, being Pont-à-Marcq, a further good sixteen miles north-westward, it was evident that the inception of that plan and the simultaneous advance of all the five columns from their five starting-points of Warcoing, Bailleul, Templeuve, Froidmont, and Pont-à-Marcq, could not begin even upon the 16th. It would take the best part of a day to bring the Arch-Duke Charles up to Pont-à-Marcq; his men were in imperative need of rest during a full night at St Amand, and it is probable, though I have no proof of it, that he had not even fully concentrated there by the evening of the 15th, and that his last units only joined him during the forenoon of the 16th. The whole of that day, therefore, the 16th, was consumed so far as the first, second, third, and fourth columns were concerned, in merely gathering and marshalling their forces, and occupying, before nightfall, the points from which they were to depart simultaneously in the combined advance of the morrow. They _had_ to wait thus for the dawn of the 17th, because they had to allow time for the fifth column to come up.
