This sealed the fate of Ypres, the key of maritime Flanders, the chief support of the right flank of the Allies, the bulwark which protected the British communications with Ostend. The Duke of York pleaded hard for a last effort to save it, by a march of the whole army to join Clerfaye; but without success. “The truth is,” wrote Craig, “that the Austrian army is incapable of further action. The men are disheartened and the officers disgusted and disunited.” It was finally decided that, to cover Ostend and the Dutch frontier, Clerfaye should take up a position between the Lys and the Scheldt about Deynse, some ten miles to the south-west of Ghent; keeping half of his force between Bruges and Ostend, and sending the Eighth Light Dragoons, Thirty-eighth and Fifty-fifth, which had formed part of his force, to Ostend. “We are too weak by ten thousand men to hold this defensive position,” wrote Craig; “if the French see their chance and push Clerfaye, they will force us to abandon this position about Tournai and will pass the Scheldt in spite of us; and then ten to one we shall find ourselves separated from him and beaten in detail.... Sooner than hold the defensive position I would concentrate the whole army, eighty thousand men, march to the Sambre, attack them at any risk and march back again.... You may expect to hear from us soon in Holland.” Clearly there was one among the despised British officers who could have taught the Austrians a lesson.[249] The situation was indeed a desperate one. The Austrians, having taken no pains to restore the fortifications of Tournai, had thrown up an entrenched camp for its protection on the western side. These lines extended from the city southward along the Scheldt to Maulde, and required so many men for their defence that few could be spared for active operations. Some seven thousand Frenchmen at Mons-en-Pévèle kept the left of the Allies in continual alarm for the safety of Orchies, which was the key of Maulde and of the passage of the Scheldt at Mortagne; for if that passage were forced, the communication between Coburg and the army of the Sambre would be endangered. A little to the north of Mons-en-Pévèle was the entire garrison of Lille, and still further to the north, between Lille and Menin, stood from twenty to thirty thousand more French troops. Behind this screen to westward, from fifty thousand to sixty thousand of the enemy were engaged as the besieging and covering armies at Ypres; and far beyond them to the north lay the right wing of the Allies under Clerfaye, stretched in a weak attenuated line from Ostend to the Lys, and only maintaining communication with Tournai by the circuitous route of the Scheldt. On the eastern flank the French had now some seventy-five thousand men on the Sambre, with a capable leader in Jourdan, albeit one still hampered by the interference of St. Just; and this was the only quarter in which recent events had gone favourably for the Allies. Such a situation could
