But what did he presume that the allied forces in Bohemia would be doing while he overwhelmed Blücher in Silesia? Would not Dresden and his communications with France be left open to their blows? He decided to run this risk. He had 100,000 men among the Lusatian hills between Bautzen and Zittau. St. Cyr's corps was strongly posted at Pirna and the small fortress of Königstein, while his light troops watched the passes north of Teplitz and Karlsbad. If the allies sought to invade Saxony, they would, so Napoleon thought, try to force the Zittau road, which presented few natural difficulties. If they threatened Dresden by the passages further west, Vandamme would march from near Zittau to reinforce St. Cyr, or, if need be, the Emperor himself would hurry back from Silesia with his Guards. If the enemy invaded Bavaria, Napoleon wished them _bon voyage_: they would soon come back faster than they went; for, in that case, he would pour his columns down from Zittau towards Prague and Vienna. The thought that he might for a time be cut off from France troubled him not: "400,000 men," he said, "resting on a system of strongholds, on a river like the Elbe, are not to be turned." In truth, he thought little about the Bohemian army. If 40,000 Russians had entered Bohemia, they would not reach Prague till the 25th; so he wrote to St. Cyr On the 17th, the day when hostilities could first begin; and he evidently believed that Dresden would be safe till September. Its defence seemed assured by the skill of that master of defensive warfare, St. Cyr, by the barrier of the Erz Mountains, and still more by Austrian slowness. Of this characteristic of theirs he cherished great hopes. Their finances were in dire disorder; and Fouché, who had just returned from a tour in the Hapsburg States, reported that the best way of striking at that Power would be "to affect its paper currency, on which all its armaments depend."[346] And truly if the transport of a great army over a mountain range had depended solely on the almost bankrupt exchequer at Vienna, Dresden would have been safe until Michaelmas; but, beside the material aid brought by the Russians and Prussians into Bohemia, England also gave her financial support. In pursuance of the secret article agreed on at Reichenbach, Cathcart now advanced £250,000 at once; and the knowledge that our financial support was given to the federative paper notes issued by the allies enabled the Court of Vienna privately to raise loans and to wage war with a vigour wholly unexpected by Napoleon.[347] Certainly the allied Grand Army suffered from no lack of advisers. The Czar, the Emperor Francis, and the King of Prussia were there; as a compliment to Austria, the command was intrusted to Field-Marshal Schwarzenberg, a man of diplomatic ability rather than of military genius. By his side were the Russians, Wittgenstein, Barclay, and Toll, the Prussian Knesebeck, the Swiss Jomini, and, above all, Moreau.
