Meanwhile, the Austrian siege work had begun, and Condé was the first object of its attention. Upon July 10 Condé fell. Meanwhile Custine had been recalled to Paris, and Valenciennes was invested. Custine was succeeded by Kilmaine, a general of Irish extraction, who maintained his position for but a short time, and was unable while he maintained it to do anything. The forces of the Allies continually increased. The number at Coburg’s disposal free from the business of besieging Valenciennes was already larger than the force required for that purpose. And yet another fifteen thousand Hessian troops marched in while the issue of that siege was in doubt. This great advantage in numbers permitted him to get rid of the main French force that was still present in front of him, though not seriously annoying him. This force lay due south-west of Valenciennes, and about a day’s march distant. He depended for the capture of it upon his English and Hanoverian Allies under the Duke of York, but that general’s march failed. The distance was too much for his troops in the hot summer weather, and the French were able to retreat behind the line of the Scarpe and save their army intact. The Duke of York’s talents have been patriotically exaggerated in many a treatise. He always failed: and this was among the most signal of his failures. Kilmaine had hardly escaped from York, drawn up his army behind the Scarpe and put it into a position of safety when he in his turn was deprived of the command, and Houchard was taken from the Rhine just as Custine had been, and put at the head of the Army of the North. Before the main French army had taken up this position of safety, Valenciennes had fallen. It fell on the 28th of July, and its fall, inevitable though it was and, as one may say, taken for granted by military opinion, was much the heaviest blow yet delivered. Nothing of importance remained to block the march of the Armies of the Allies, save Maubeuge. At about the same moment occurred three very important changes in the general military situation, which the reader must note if he is to understand what follows. The first was the sudden serious internal menace opposed to the Republican Government; the second was the advent of Carnot to power; the third was the English diversion upon Dunquerque.
