The secret how Wallenstein had purposed to fulfill his extravagant designs was now manifest. He had learned the lesson from Count Mansfeld,[25] but the scholar surpassed his master. On the principle that war must support war, Mansfeld and the Duke of Brunswick had subsisted their troops by contributions levied indiscriminately on friend and enemy; but this predatory life was attended with all the inconvenience and insecurity which accompany robbery. Like fugitive banditti, they were obliged to steal through exasperated and vigilant enemies; to roam from one end of Germany to another; to watch their opportunity with anxiety, and to abandon the most fertile territories whenever they were defended by a superior army. If Mansfeld and Duke Christian had done such great things in the face of these difficulties, what might not be expected if the obstacles were removed; when the army raised was numerous enough to overawe in itself the most powerful states of the empire; when the name of the emperor insured impunity to every outrage; and when, under the highest authority, and at the head of an overwhelming force, the same system of warfare was pursued which these two adventurers had hitherto adopted at their own risk, and with only an untrained multitude? Wallenstein was at the head of an army of nearly a hundred thousand men, who adored him, when the sentence of his dismissal arrived. Most of the officers were his creatures--with the common soldiers his hint was law. His ambition was boundless, his pride indomitable, his imperious spirit could not brook an injury unavenged. One moment would now precipitate him from the height of grandeur into the obscurity of a private station. To execute such a sentence upon such a delinquent seemed to require more address than it cost to obtain it from the judge. Accordingly, two of Wallenstein’s most intimate friends were selected as heralds of these evil tidings, and instructed to soften them as much as possible by flattering assurances of the continuance of the emperor’s favor.
