On the 18th of January, 1742, Frederick visited Dresden, to confer with Augustus III., King of Poland, who was also Elector of Saxony, and whose realms were to be increased by the annexation of Moravia. His Polish majesty was a weak man, entirely devoted to pleasure. His irresolute mind, subjected to the dominant energies of the Prussian king, was as clay in the hands of the potter. “You are now,” said Frederick, “by consent of the allies, King of Moravia. Now is the time, now or never, to become so in fact. Push forward your Saxon troops. The Austrian forces are weak in that country. At Iglau, just over the border from Austria, there is a large magazine of military stores, which can easily be seized. Urge forward your troops. The French will contribute strong divisions. I will join you with twenty thousand men. We can at once take possession of Moravia, and perhaps march directly on to Vienna.” Frederick, in describing this interview, writes: “Augustus answered _yes_ to every thing, with an air of being convinced, joined to a look of great _ennui_. Count Brühl,[61] whom this interview displeased, interrupted it by announcing to his majesty that the Opera was about to commence. Ten kingdoms to conquer would not have kept the King of Poland a minute longer. He went, therefore, to the Opera; and the King of Prussia obtained at once, in spite of those who opposed it, a final decision.”[62] The next morning, in the intense cold of midwinter, Frederick set out several hours before daylight for the city of Prague, which the French and Bavarians had captured on the 25th of November. Declining all polite attentions, for business was urgent, he eagerly sought M. De Séchelles, the renowned head of the commissariat department, and made arrangements with him to perform the extremely difficult task of supplying the army with food in a winter’s campaign. The next morning, at an early hour, he again dashed off to the east, toward Glatz, a hundred miles distant, where a portion of the Prussian troops were in cantonments, under the young Prince Leopold. Within a week he had ridden over seven hundred miles, commencing his journey every morning as early as four o’clock, and doing a vast amount of business by the way.
