If Gustavus Adolphus owed his success chiefly to his own genius, at the same time, it must be owned, he was greatly favoured by fortune and by circumstances. Two great advantages gave him a decided superiority over the enemy. While he removed the scene of war into the lands of the League, drew their youth as recruits, enriched himself with booty, and used the revenues of their fugitive princes as his own, he at once took from the enemy the means of effectual resistance, and maintained an expensive war with little cost to himself. And, moreover, while his opponents, the princes of the League, divided among themselves, and governed by different and often conflicting interests, acted without unanimity, and therefore without energy;while their generals were deficient in authority, their troops in obedience, the operations of their scattered armies without concert;while the general was separated from the lawgiver and the statesman;these several functions were united in Gustavus Adolphus, the only source from which authority flowed, the sole object to which the eye of the warrior turned; the soul of his party, the inventor as well as the executor of his plans. In him, therefore, the Protestants had a centre of unity and harmony, which was altogether wanting to their opponents. No wonder, then, if favoured by such advantages, at the head of such an army, with such a genius to direct it, and guided by such political prudence, Gustavus Adolphus was irresistible.
With the sword in one hand, and mercy in the other, he traversed Germany as a conqueror, a lawgiver, and a judge, in as short a time almost as the tourist of pleasure. The keys of towns and fortresses were delivered to him, as if to the native sovereign. No fortress was inaccessible;no river checked his victorious career. He conquered by the very terror of his name. The Swedish standards were planted along the whole stream of the Maine: the Lower Palatinate was free, the troops of Spain and Lorraine had fled across the Rhine and the Moselle. The Swedes and Hessians poured like a torrent into the territories of Mentz, of Wurtzburg, and Bamberg, and three fugitive bishops, at a distance from their sees, suffered dearly for their unfortunate attachment to the Emperor.
It was now the turn for Maximilian, the leader of the League, to feel in his own dominions the miseries he had inflicted upon others.
Neither the terrible fate of his allies, nor the peaceful overtures of Gustavus, who, in the midst of conquest, ever held out the hand of friendship, could conquer the obstinacy of this prince.
The torrent of war now poured into Bavaria. Like the banks of the Rhine, those of the Lecke and the Donau were crowded with Swedish troops.
Creeping into his fortresses, the defeated Elector abandoned to the ravages of the foe his dominions, hitherto unscathed by war, and on which the bigoted violence of the Bavarians seemed to invite retaliation.
Munich itself opened its gates to the invincible monarch, and the fugitive Palatine, Frederick V., in the forsaken residence of his rival, consoled himself for a time for the loss of his dominions.
While Gustavus Adolphus was extending his conquests in the south, his generals and allies were gaining similar triumphs in the other provinces.
Lower Saxony shook off the yoke of Austria, the enemy abandoned Mecklenburg, and the imperial garrisons retired from the banks of the Weser and the Elbe.
In Westphalia and the Upper Rhine, William, Landgrave of Hesse, rendered himself formidable; the Duke of Weimar in Thuringia, and the French in the Electorate of Treves; while to the eastward the whole kingdom of Bohemia was conquered by the Saxons.
The Turks were preparing to attack Hungary, and in the heart of Austria a dangerous insurrection was threatened. In vain did the Emperor look around to the courts of Europe for support; in vain did he summon the Spaniards to his assistance, for the bravery of the Flemings afforded them ample employment beyond the Rhine; in vain did he call upon the Roman court and the whole church to come to his rescue.
The offended Pope sported, in pompous processions and idle anathemas, with the embarrassments of Ferdinand, and instead of the desired subsidy he was shown the devastation of Mantua.
On all sides of his extensive monarchy hostile arms surrounded him.
With the states of the League, now overrun by the enemy, those ramparts were thrown down, behind which Austria had so long defended herself, and the embers of war were now smouldering upon her unguarded frontiers.
His most zealous allies were disarmed; Maximilian of Bavaria, his firmest support, was scarce able to defend himself. His armies, weakened by desertion and repeated defeat, and dispirited by continued misfortunes had unlearnt, under beaten generals, that warlike impetuosity which, as it is the consequence, so it is the guarantee of success. The danger was extreme, and extraordinary means alone could raise the imperial power from the degradation into which it was fallen.
The most urgent want was that of a general; and the only one from whom he could hope for the revival of his former splendour, had been removed from his command by an envious cabal.
So low had the Emperor now fallen, that he was forced to make the most humiliating proposals to his injured subject and servant, and meanly to press upon the imperious Duke of Friedland the acceptance of the powers which no less meanly had been taken from him.
