Napoleon's first instinct of treachery was that of the general, and it was sound. His suspicions were fully aroused as soon as he reached Dresden; for Bubna began at once to stickle for antiquated formalities in negotiation, and stung Napoleon to exasperation by his evident determination to procrastinate. Accordingly the Emperor summoned Metternich to a personal meeting. The minister could not well explain. Since Castlereagh's return to power in January, 1812, Great Britain had kept at Berlin, St. Petersburg, and Vienna able diplomats ready, with purse in hand, to pay almost any sum for a strong coalition. It had been the appearance of Sir Charles Stewart from Berlin, and of Lord Cathcart from St. Petersburg, at the allied headquarters which accounted for the arrogant firmness of Shuvaloff and Kleist, and determined the character of the armistice. On June fourteenth and fifteenth those envoys further concluded treaties with Prussia and Russia respectively which explain the performances of Bubna at Dresden, and of the congress which later met at Prague. Prussia promised, in return for a subsidy of two thirds of a million pounds sterling, to cede a certain portion of lower Saxony, with the bishopric of Hildesheim, to the electorate of Hanover, and agreed to keep on foot eighty thousand men; Russia was to maintain a hundred and sixty thousand men, in return for one and a third million pounds, and for the care of English vessels in her harbors she was to receive a further sum of half a million. Great Britain and Russia were in conjunction to emit an issue of paper money to the amount of five millions sterling, and this loan was to be guaranteed by England, Prussia, and Russia conjointly. In conclusion it was solemnly stipulated that neither Russia nor Great Britain should negotiate separately with France.
