The time-table imposed upon the great plan by these delays is now apparent. The moment when all the strings of the net were to be pulled together round Souham was the space between midnight and dawn of Saturday the 17th of May. And the hour when all the six bodies of the allies were to join hands at "R" near Tourcoing was the noon of that day. Before day broke upon the 17th, Clerfayt was to find himself at Wervicq upon the River Lys and across that stream, while of the five southern columns the Arch-Duke Charles was to be attacking the French troops just in front of Pont-à-Marcq with the fifth column at the same moment; Kinsky, with the fourth, was to be well on the way from Froidmont to Bouvines where he was to attack the French also and cross the bridge; the Duke of York, with the third, was to be well on the way from Templeuve to Lannoy; Otto, with the second, was to be equally advanced upon his line, somewhere by Wattrelos in his march upon Tourcoing; while Bussche, with his small first column, on the extreme north, was to be getting into contact with the French posts south of Courtrai, which it was his duty to "hold," impressing upon Souham the idea that a main attack might develop in that quarter, and so deluding the French into maintaining their perilously advanced stations until they were cut off from Lille by the rest of the allies. The morning would be filled by the advance of Clerfayt from Wervicq southward upon Mouveaux and Tourcoing, while the corresponding fighting advance northward upon Mouveaux and Tourcoing also, of Otto, York, Kinsky, and the Arch-Duke Charles, should result somewhere about noon in their joining hands with Clerfayt and forming one great body: a body cutting off Courtrai from Lille, and the 40,000 under Souham from their fellows in the main French line. With such a time-table properly observed, the plan should have succeeded, and between the noon and the evening of that Saturday, the great force which Souham commanded should have been at the mercy of the allies. * * * * * Such was the plan and such the time-table upon which it was schemed. Its success depended, of course, as I have said, upon an exact keeping of that time-table, and also upon the net being drawn round Souham before he had guessed what was happening. The second of these conditions, we shall see when we come to speak of "The Preliminaries of the Action," was successfully accomplished. The first was not; and its failure is the story of the defeat suffered by the Duke of York in particular, and the consequent break-down of the whole strategical conception of the allies. * * * * * But before dealing with this it is necessary to establish a disputed point.
