But the demon of despotism, who never sleeps, raised up to his assistance a great military genius. This was Wallenstein, Duke of Friedland, the richest noble in Bohemia. The person whom he most resembled, in that age of struggle and contending forces, when despotism sought unscrupulous agents, was Thomas Wentworth, Earl of Strafford,--the right hand of Charles I., in his warfare against the liberties of England. Like Stratford, he was an apostate from the principles in which he had been educated; like him, he had arisen from a comparatively humble station; like him, his talents were as commanding as his ambition,--devoted first to his own exaltation; and, secondly, to the cause of absolutism, with which he sympathized with all the intensity that a proud and domineering spirit may be supposed to feel for the struggles of inexperienced democracy. Like the English statesman, the German general was a Jesuit in the use of tools, jealous of his authority, liberal in his rewards, and fearful in his vengeance. Though greedy of admiration and fond of display, he surrounded himself with mystery and gloom. Like Strafford, he was commanding in his person, dignified, reserved, and sullen; with an eye piercing and melancholy, a brow lowering with thought and care, and a lip compressed into determination and twisted into a smile of ironical disdain. This nobleman had fought with distinction as a colonel at the battle of Prague, when Bohemian liberties had been prostrated, and had signally distinguished himself in his infamous crusade against his own countrymen. He offered, at his own expense, to raise and equip an army of fifty thousand men in the service of the Emperor; but demanded as a condition, that he should have the appointment of all his officers, and the privilege of enriching himself and army from the spoils and confiscations of conquered territories. These terms were extraordinary and humiliating to an absolute sovereign, yet, at the crisis in which Ferdinand was placed, they were too tempting to be refused.
