Gustavus Adolphus, naturally apprehensive of the consequences which the defection of so powerful an ally would produce on his future prospects in Germany, spared no pains to avert so pernicious an event; and his remonstrances had hitherto had some effect upon the Elector. But the formidable power with which the Emperor seconded his seductive proposals, and the miseries which, in the case of hesitation, he threatened to accumulate upon Saxony, might at length overcome the resolution of the Elector, should he be left exposed to the vengeance of his enemies; while an indifference to the fate of so powerful a confederate, would irreparably destroy the confidence of the other allies in their protector. This consideration induced the king a second time to yield to the pressing entreaties of the Elector, and to sacrifice his own brilliant prospects to the safety of this ally. He had already resolved upon a second attack on Ingoldstadt; and the weakness of the Elector of Bavaria gave him hopes of soon forcing this exhausted enemy to accede to a neutrality. An insurrection of the peasantry in Upper Austria, opened to him a passage into that country, and the capital might be in his possession, before Wallenstein could have time to advance to its defence. All these views he now gave up for the sake of an ally, who, neither by his services nor his fidelity, was worthy of the sacrifice; who, on the pressing occasions of common good, had steadily adhered to his own selfish projects; and who was important, not for the services he was expected to render, but merely for the injuries he had it in his power to inflict. Is it possible, then, to refrain from indignation, when we know that, in this expedition, undertaken for the benefit of such an ally, the great king was destined to terminate his career? Rapidly assembling his troops in Franconia, he followed the route of Wallenstein through Thuringia. Duke Bernard of Weimar, who had been despatched to act against Pappenheim, joined the king at Armstadt, who now saw himself at the head of 20,000 veterans. At Erfurt he took leave of his queen, who was not to behold him, save in his coffin, at Weissenfels. Their anxious adieus seemed to forbode an eternal separation.
