Mack, as we have seen, was one of those men who easily surrender their will-power to bolder spirits. Accordingly, Schulmeister, who possessed the Austrian's complete confidence and who was well assisted by his Austrian fellow-spies, Wend and Rulski, acting on the instructions transmitted to him by Napoleon's headquarters, kept the Field-Marshal, by means of forged communications purporting to come from traitors in the French camp, falsely informed as to the movements of the three advancing imperial armies. As an aristocrat and a convinced supporter of all feudalistic forms and ideals, Mack was easily led to believe that the newly established throne of the Corsican received but half-hearted adherence from the French people. Napoleon even had newspapers especially printed which were to be shown to Mack in order to strengthen this impression. According, also, to letters supplied by the spy, Napoleon, who had left Paris with Vienna as his objective, had been forced to return with the greater part of his armies in order to quell a revolution which had broken out against his throne on his departure from the French capital. Coincident reports, supplied by Schulmeister's paid collaborants, seemed to point to the truth of the Alsatian's startling intelligence, and acting upon it, the Austrian Field-Marshal, with an army of 30,000 men, issued from the city of Ulm in pursuit of what he thought to be the retreating French armies only to find himself surrounded by a ring of steel, or what Napoleon was wont to term his "necklace" manœuvre, Soult, Marmont, Lannes, Ney, Dupont and Murat closing him in on all sides. The memorable capitulation of the city, a pivotal point in the set strategy of Austria's military plans for the campaign of 1805, followed at once, Mack paying the penalty of what was for long thought to be an act of treachery, by being deprived of his rank, with a further punishment of two years in a military fortress. As for Schulmeister himself, his audacity never showed itself more conspicuously than in the immediate sequel. Not content with having practically assured to Napoleon the success of what is known as the Austerlitz campaign, admittedly the most spectacular of all the Emperor's military exploits, the spy, after Mack's disgrace, repaired to Vienna, where in the chief military councils, which were attended by the Emperor Francis and the Emperor of Russia, he is said to have counselled plans which were sure, he said, to enable the Allies to offset the disaster of Ulm and redeem the situation. Strange though it appears, his views, supported as usual by forged letters of intelligence, were applauded by the military commanders present, and the result was the shattering of the Austro-Russian armies at Austerlitz on 2nd December 1805. On the morrow of that memorable conflict, the spy was arrested at the instance of highly placed persons in Vienna who had long suspected him. The
