The fourth column, under Kinsky, about 11,000 strong, was also ready on that Friday, the 16th of May, concentrated at its point of departure, Froidmont, and ready to move at the same moment as all the others, shortly after midnight. But unlike the other three commanders upon his right, Kinsky was unfortunately handicapped by the position of the fifth column, that great body of 18,000 to 20,000 men, under the Arch-Duke Charles, which lay at St Amand, which was to advance next day parallel with Kinsky and upon his left, and which it was his duty to keep in touch with, and to link up with the Duke of York's upon the other side. He was handicapped, I say, by the situation of the fifth column, under the Arch-Duke Charles, the heavy strain already imposed upon which, and the accumulating difficulties it was about to encounter, largely determining the unfortunate issue of the battle. Kinsky got news on that Friday from the Arch-Duke at St Amand that it was hardly possible for his great body of men to reach the appointed post of Pont-à-Marcq at the arranged hour of daybreak the next morning. I have already suggested that this delay cannot only have been due to the very long march which had been imposed upon the Arch-Duke's command when it had been hurriedly summoned up from the south to St Amand, forty-eight hours before. It must also have been due to the fact that not all its units reached St Amand by the evening of Thursday the 15th. It seemed certain that there must have been stragglers or bad delays on the morning of the 16th, for it was not until long after nightfall--indeed not until ten o'clock in the evening--of Friday the 16th that the Arch-Duke was able to set out from St Amand and take the Pont-à-Marcq road. This unfortunate body, therefore, the fifth column, which had all the hardest work before it, which had but one road by which to march (although it was double any of the others in size), was compelled, after the terrible fatigue of the preceding days, to push forward sixteen miles through the night in a vain attempt to reach Pont-à-Marcq, not indeed by daybreak, for that was obviously impossible, but as soon after as haste and anxiety could command. Kinsky was tied to Froidmont and unable to move forward until that fifth column upon his left was at least approaching its goal. For he had Bonnaud's 20,000 Frenchmen at Sainghin right in front of him, and further, if he had moved, his left flank would have been exposed, and, what is more, he would have failed in his purpose, which was to link up the Arch-Duke on one side with the Duke of York upon the other. This first mishap, then, must be carefully noted as one prime lack of synchrony in the origins of the combined movement, and a first clear cause of the misfortune that was to attend the whole affair. The delay of the fifth column was the chief cause of the disaster.
