Clerfayt had first advanced—but far too late to save the centre—and then retreated. The Archduke Charles, upon the left, was four hours late in marching to the help of the Duke of York; the right wing of the Allies was not even late: it spent the morning in an orderly artillery duel with the French force opposed to it. By five in the afternoon defeat was admitted and a general retreat of the Allies ordered.
I have said that many reasons are given to account for the disaster of Tourcoing, one of the very few in which a British force has been routed upon the Continent; but I confess that if I were asked for an explanation of my own, I would say that it was simply due to the gross lack of synchrony on the part of the Allies, and that this in its turn was taken advantage of by the power both of vigil and of marching which the French troops, still inferior in most military characteristics, had developed and maintained, and which (a more important matter) their commanders knew how to use.
This heavy blow, delivered on the 18th of May, in spite of a successful rally a week later, finally convinced the Emperor that the march on Paris was impossible. Eleven days later, on the 29th, it was announced in the camp of Tournay, upon which the Allied army had fallen back, that the Emperor had determined to return to Vienna. The Allied army was indeed still left upon that front, but the French continued to pour up against it. It was again their numbers that brought about the next and the final victory.
Far off, upon the east of that same line, the army which is famous in history and in song as that of the Sambre et Meuse was violently attempting to cross the Sambre and to turn the line of the Allies. Coburg reinforced his right opposite the French left, but numbers had begun to bewilder him. The enthusiasm of Saint-Just, the science of Carnot, decided victory at this eastern end of the line.
Six times the passage of the Sambre had failed. Reinforcements continued to reach the army, and the seventh attempt succeeded.
Charleroi, which is the main fortress blocking the passage of the Sambre at this place, could be, and was, invested when once the river was crossed by the French. It capitulated in a week. But the evacuation of Charleroi was but just accomplished when Coburg, seventy thousand strong, appeared in relief of the city.
Showing effect of Ypres, Charleroi and Fleurus in wholly throwing back the Allies in June 1794.
Ypres captured on June 19 by the French, they march on Oudenarde and pass it on June 25 to 27. Meanwhile Charleroi has also surrendered to the French, and when, immediately afterwards, the Austrians try to relieve it, they are beaten at Fleurus and retire on Brussels.
Thus the English at Tournai and all the Allied Forces at Condé, Valenciennes, Landrecies, and Mons are imperilled and must surrender or retire.
