his eye was upon everything going on in Germany, and indeed in Europe. He was watching for a favorable moment for revenge, and the retrieving of his fortunes.
The opportunity which Wallenstein, inspired by faith in his star, was so confidently awaiting was not long delayed. Only a few months before his dismissal from the Imperial service, Gustavus Adolphus, king of Sweden, with a veteran and enthusiastic army of 16,000 Swedes, had appeared in Northern Germany as the champion of the dispirited and leaderless Protestants. The Protestant princes, however, through fear of the emperor, as well as from lack of confidence in the disinterestedness of the motives of Gustavus, were shamefully backward in rallying to the support of their deliverer. But through an alliance formed just now with France, the Swedish king received a large annual subsidy from that country, which, with the help he was receiving from England, made him a formidable antagonist.
The wavering, jealous, and unworthy conduct of the Protestant princes now led to a most terrible disaster. At this moment Tilly was besieging the city of Magdeburg, which had dared to resist the Edict of Restitution (see p. 583). Gustavus was prevented from giving relief to the place by the hindrances thrown in his way by the Electors of Brandenburg and Saxony, both of whom should have given him every assistance. In a short time the city was obliged to surrender, and was given up to sack and pillage. Everything was burned, save two churches and a few hovels. 30,000 of the inhabitants perished miserably.
The cruel fate of Magdeburg excited the alarm of the Protestant princes. The Elector of Saxony now at once united his forces with those of the Swedish king. Tilly was defeated with great loss in the celebrated battle of Leipsic (1631), and Gustavus, emboldened by his success, pushed southward into the very heart of Germany. Attempting to dispute his march, Tilly's army was again defeated, and he himself received a fatal wound. In the death of Tilly, Ferdinand lost his most trustworthy general (1632).
