archbishopric of Magdeburg; and field-marshal Arnheim, his new favourite and minister, spared no pains to increase the resentment of his master. Arnheim had formerly been an imperial general under Wallenstein, and being still zealously attached to him, he was eager to avenge his old benefactor and himself on the Emperor, by detaching Saxony from the Austrian interests. Gustavus Adolphus, supported by the Protestant states, would be invincible; a consideration which already filled the Emperor with alarm. The example of Saxony would probably influence others, and the Emperor's fate seemed now in a manner to depend upon the Elector's decision. The artful favourite impressed upon his master this idea of his own importance, and advised him to terrify the Emperor, by threatening an alliance with Sweden, and thus to extort from his fears, what he had sought in vain from his gratitude. The favourite, however, was far from wishing him actually to enter into the Swedish alliance, but, by holding aloof from both parties, to maintain his own importance and independence. Accordingly, he laid before him a plan, which only wanted a more able hand to carry it into execution, and recommended him, by heading the Protestant party, to erect a third power in Germany, and thereby maintain the balance between Sweden and Austria.
This project was peculiarly flattering to the Saxon Elector, to whom the idea of being dependent upon Sweden, or of longer submitting to the tyranny of the Emperor, was equally hateful. He could not, with indifference, see the control of German affairs wrested from him by a foreign prince; and incapable as he was of taking a principal part, his vanity would not condescend to act a subordinate one. He resolved, therefore, to draw every possible advantage from the progress of Gustavus, but to pursue, independently, his own separate plans. With this view, he consulted with the Elector of Brandenburg, who, from similar causes, was ready to act against the Emperor, but, at the same time, was jealous of Sweden. In a Diet at Torgau, having assured himself of the support of his Estates, he invited the Protestant States of the empire to a general convention, which took place at Leipzig, on the 6th February 1631. Brandenburg, Hesse Cassel, with several princes, counts, estates of the empire, and Protestant bishops were present, either personally or by deputy, at this assembly, which the chaplain to the Saxon Court, Dr. Hoe von Hohenegg, opened with a vehement discourse from the pulpit. The Emperor had, in vain, endeavoured to prevent this self-appointed convention, whose object was evidently to provide for its own defence, and which the presence of the Swedes in the empire, rendered more than usually alarming. Emboldened by the progress of Gustavus Adolphus, the assembled princes asserted their rights, and after a session of two months broke up, with adopting a resolution which placed the Emperor in no slight embarrassment. Its import was to demand of the Emperor, in a general address, the revocation of the Edict of Restitution, the withdrawal of his troops from their capitals and fortresses, the suspension of all existing proceedings, and the abolition of abuses; and, in the mean time, to raise an army of 40,000 men, to enable them to redress their own grievances, if the Emperor should still refuse satisfaction.
A further incident contributed not a little to increase the firmness of the Protestant princes. The King of Sweden had, at last, overcome the scruples which had deterred him from a closer alliance with France, and, on the 13th January 1631, concluded a formal treaty with this crown. After a serious dispute respecting the treatment of the Roman Catholic princes of the empire, whom France took under her protection, and against whom Gustavus claimed the right of retaliation, and after some less important differences with regard to the title of majesty, which the pride of France was loth to concede to the King of Sweden, Richelieu yielded the second, and Gustavus Adolphus the first point, and the treaty was signed at Beerwald in Neumark. The contracting parties mutually covenanted to defend each other with a military force, to protect their common friends, to restore to their dominions the deposed princes of the empire, and to replace every thing, both on the frontier and in the interior of Germany, on the same footing on which it stood before the commencement of the war. For this end, Sweden engaged to maintain an army of 30,000 men in Germany, and France agreed to furnish the Swedes with an annual subsidy of 400,000 dollars. If the arms of Gustavus were successful, he was to respect the Roman Catholic religion and the constitution of the empire in all the conquered places, and to make no attempt against either. All Estates and princes whether Protestant or Roman Catholic, either in Germany or in other countries, were to be invited to become parties to the treaty; neither France nor Sweden was to conclude a separate peace without the knowledge and consent of the other; and the treaty itself was to continue in force for five years.
Great as was the struggle to the King of Sweden to receive subsidies from France, and sacrifice his independence in the conduct of the war, this alliance with France decided his cause in Germany. Protected, as he now was, by the greatest power in Europe, the German states began to feel confidence in his undertaking, for the issue of which they had hitherto good reason to tremble. He became truly formidable to the Emperor. The Roman Catholic princes too, who, though they were anxious to humble Austria, had witnessed his progress with distrust, were less alarmed now that an alliance with a Roman Catholic power ensured his respect for their religion. And thus, while Gustavus Adolphus protected the Protestant religion and the liberties of Germany against the aggression of Ferdinand, France secured those liberties, and the Roman Catholic religion, against Gustavus himself, if the intoxication of success should hurry him beyond the bounds of moderation.
The King of Sweden lost no time in apprizing the members of the confederacy of Leipzig of the treaty concluded with France, and inviting them to a closer union with himself. The application was seconded by France, who spared no pains to win over the Elector of Saxony. Gustavus was willing to be content with secret support, if the princes should deem it too bold a step as yet to declare openly in his favour. Several princes gave him hopes of his proposals being accepted on the first favourable opportunity; but the Saxon Elector, full of jealousy and distrust towards the King of Sweden, and true to the selfish policy he had pursued, could not be prevailed upon to give a decisive answer.
The resolution of the confederacy of Leipzig, and the alliance betwixt France and Sweden, were news equally disagreeable to the Emperor. Against them he employed the thunder of imperial ordinances, and the want of an army saved France from the full weight of his displeasure. Remonstrances were addressed to all the members of the confederacy, strongly prohibiting them from enlisting troops. They retorted with explanations equally vehement, justified their conduct upon the principles of natural right, and continued their preparations.
Meantime, the imperial generals, deficient both in troops and money, found themselves reduced to the disagreeable alternative of losing sight either of the King of Sweden, or of the Estates of the empire, since with a divided force they were not a match for either. The movements of the Protestants called their attention to the interior of the empire, while the progress of the king in Brandenburg, by threatening the hereditary possessions of Austria, required them to turn their arms to that quarter. After the conquest of Frankfort, the king had advanced upon Landsberg on the Warta, and Tilly, after a fruitless attempt to relieve it, had again returned to Magdeburg, to prosecute with vigour the siege of that town.
The rich archbishopric, of which Magdeburg was the capital, had long been in the possession of princes of the house of Brandenburg, who introduced the Protestant religion into the province. Christian William, the last administrator, had, by his alliance with Denmark, incurred the ban of the empire, on which account the chapter, to avoid the Emperor's displeasure, had formally deposed him. In his place they had elected Prince John Augustus, the second son of the Elector of Saxony, whom the Emperor rejected, in order to confer the archbishopric on his son Leopold. The Elector of Saxony complained ineffectually to the imperial court; but Christian William of Brandenburg took more active measures. Relying on the attachment of the magistracy and inhabitants of Brandenburg, and excited by chimerical hopes, he thought himself able to surmount all the obstacles which the vote of the chapter, the competition of two powerful rivals, and the Edict of Restitution opposed to his restoration. He went to Sweden, and, by the promise of a diversion in Germany, sought to obtain assistance from Gustavus. He was dismissed by that monarch not without hopes of effectual protection, but with the advice to act with caution.
Scarcely had Christian William been informed of the landing of his protector in Pomerania, than he entered Magdeburg in disguise. Appearing suddenly in the town council, he reminded the magistrates of the ravages which both town and country had suffered from the imperial troops, of the pernicious designs of Ferdinand, and the danger of the Protestant church. He then informed them that the moment of deliverance was at hand, and that Gustavus Adolphus offered them his alliance and assistance. Magdeburg, one of the most flourishing towns in Germany, enjoyed under the government of its magistrates a republican freedom, which inspired its citizens with a brave heroism. Of this they had already given proofs, in the bold defence of their rights against Wallenstein, who, tempted by their wealth, made on them the most extravagant demands. Their territory had been given up to the fury of his troops, though Magdeburg itself had escaped his vengeance. It was not difficult, therefore, for the Administrator to gain the concurrence of men in whose minds the rememberance of these outrages was still recent. An alliance was formed between the city and the Swedish king, by which Magdeburg granted to the king a free passage through its gates and territories, with liberty of enlisting soldiers within its boundaries, and on the other hand, obtained promises of effectual protection for its religion and its privileges.
