Count Wallenstein, afterward Duke of Friedland, was an experienced officer, and the richest nobleman in Bohemia. From his earliest youth he had been in the service of the house of Austria, and several campaigns against the Turks, Venetians, Bohemians, Hungarians, and Transylvanians had established his reputation. He was present as colonel at the battle of Prague, and afterward, as major-general, had defeated a Hungarian force in Moravia. The emperor’s gratitude was equal to his services, and a large share of the confiscated estates of the Bohemian insurgents was their reward. Possessed of immense property, excited by ambitious views, confident of his own good fortune, and still more encouraged by the existing state of circumstances, he offered, at his own expense and that of his friends, to raise and clothe an army for the emperor, and even undertook the cost of maintaining it if he were allowed to augment it to fifty thousand men. The project was universally ridiculed as the chimerical offering of a visionary brain; but the offer was highly valuable, if its promises should be but partly fulfilled. Certain circles in Bohemia were assigned to him as depots, with authority to appoint his own officers. In a few months he had twenty thousand men under arms, with which, quitting the Austrian territories, he soon afterward appeared on the frontiers of Lower Saxony with thirty thousand. The emperor had lent this armament nothing but his name. The reputation of the general, the prospect of rapid promotion, and the hope of plunder, attracted to his standard adventurers from all quarters of Germany, and even sovereign princes, stimulated by the desire of glory or of gain, offered to raise regiments for the service of Austria.
