Gustavus Adolphus had not completed his seventeenth year, when the Swedish throne became vacant by the death of his father. But the early maturity of his genius enabled the Estates to abridge in his favour the legal period of minority. With a glorious conquest over himself he commenced a reign which was to have victory for its constant attendant, a career which was to begin and end in success. The young Countess of Brahe, the daughter of a subject, had gained his early affections, and he had resolved to share with her the Swedish throne. But, constrained by time and circumstances, he made his attachment yield to the higher duties of a king, and heroism again took exclusive possession of a heart which was not destined by nature to confine itself within the limits of quiet domestic happiness.
Christian IV. of Denmark, who had ascended the throne before the birth of Gustavus, in an inroad upon Sweden, had gained some considerable advantages over the father of that hero. Gustavus Adolphus hastened to put an end to this destructive war, and by prudent sacrifices obtained a peace, in order to turn his arms against the Czar of Muscovy. The questionable fame of a conqueror never tempted him to spend the blood of his subjects in unjust wars; but he never shrunk from a just one. His arms were successful against Russia, and Sweden was augmented by several important provinces on the east.
In the meantime, Sigismund of Poland retained against the son the same sentiments of hostility which the father had provoked, and left no artifice untried to shake the allegiance of his subjects, to cool the ardour of his friends, and to embitter his enemies. Neither the great qualities of his rival, nor the repeated proofs of devotion which Sweden gave to her loved monarch, could extinguish in this infatuated prince the foolish hope of regaining his lost throne. All Gustavus's overtures were haughtily rejected. Unwillingly was this really peaceful king involved in a tedious war with Poland, in which the whole of Livonia and Polish Prussia were successively conquered. Though constantly victorious, Gustavus Adolphus was always the first to hold out the hand of peace.
This contest between Sweden and Poland falls somewhere about the beginning of the Thirty Years' War in Germany, with which it is in some measure connected. It was enough that Sigismund, himself a Roman Catholic, was disputing the Swedish crown with a Protestant prince, to assure him the active support of Spain and Austria; while a double relationship to the Emperor gave him a still stronger claim to his protection. It was his reliance on this powerful assistance that chiefly encouraged the King of Poland to continue the war, which had hitherto turned out so unfavourably for him, and the courts of Madrid and Vienna failed not to encourage him by high-sounding promises. While Sigismund lost one place after another in Livonia, Courland, and Prussia, he saw his ally in Germany advancing from conquest after conquest to unlimited power. No wonder then if his aversion to peace kept pace with his losses. The vehemence with which he nourished his chimerical hopes blinded him to the artful policy of his confederates, who at his expense were keeping the Swedish hero employed, in order to overturn, without opposition, the liberties of Germany, and then to seize on the exhausted North as an easy conquest. One circumstance which had not been calculated on -- the magnanimity of Gustavus -- overthrew this deceitful policy. An eight years' war in Poland, so far from exhausting the power of Sweden, had only served to mature the military genius of Gustavus, to inure the Swedish army to warfare, and insensibly to perfect that system of tactics by which they were afterwards to perform such wonders in Germany.
After this necessary digression on the existing circumstances of Europe, I now resume the thread of my history.
Ferdinand had regained his dominions, but had not indemnified himself for the expenses of recovering them. A sum of forty millions of florins, which the confiscations in Bohemia and Moravia had produced, would have sufficed to reimburse both himself and his allies; but the Jesuits and his favourites soon squandered this sum, large as it was. Maximilian, Duke of Bavaria, to whose victorious arm, principally, the Emperor owed the recovery of his dominions; who, in the service of religion and the Emperor, had sacrificed his near relation, had the strongest claims on his gratitude; and moreover, in a treaty which, before the war, the duke had concluded with the Emperor, he had expressly stipulated for the reimbursement of all expenses. Ferdinand felt the full weight of the obligation imposed upon him by this treaty and by these services, but he was not disposed to discharge it at his own cost. His purpose was to bestow a brilliant reward upon the duke, but without detriment to himself. How could this be done better than at the expense of the unfortunate prince who, by his revolt, had given the Emperor a right to punish him, and whose offences might be painted in colours strong enough to justify the most violent measures under the appearance of law. That, then, Maximilian may be rewarded, Frederick must be further persecuted and totally ruined; and to defray the expenses of the old war, a new one must be commenced.
But a still stronger motive combined to enforce the first. Hitherto Ferdinand had been contending for existence alone; he had been fulfilling no other duty than that of self-defence. But now, when victory gave him freedom to act, a higher duty occurred to him, and he remembered the vow which he had made at Loretto and at Rome, to his generalissima, the Holy Virgin, to extend her worship even at the risk of his crown and life. With this object, the oppression of the Protestants was inseparably connected. More favourable circumstances for its accomplishment could not offer than those which presented themselves at the close of the Bohemian war. Neither the power, nor a pretext of right, were now wanting to enable him to place the Palatinate in the hands of the Catholics, and the importance of this change to the Catholic interests in Germany would be incalculable. Thus, in rewarding the Duke of Bavaria with the spoils of his relation, he at once gratified his meanest passions and fulfilled his most exalted duties; he crushed an enemy whom he hated, and spared his avarice a painful sacrifice, while he believed he was winning a heavenly crown.
In the Emperor's cabinet, the ruin of Frederick had been resolved upon long before fortune had decided against him; but it was only after this event that they ventured to direct against him the thunders of arbitrary power. A decree of the Emperor, destitute of all the formalities required on such occasions by the laws of the Empire, pronounced the Elector, and three other princes who had borne arms for him at Silesia and Bohemia, as offenders against the imperial majesty, and disturbers of the public peace, under the ban of the empire, and deprived them of their titles and territories. The execution of this sentence against Frederick, namely the seizure of his lands, was, in further contempt of law, committed to Spain as Sovereign of the circle of Burgundy, to the Duke of Bavaria, and the League. Had the Evangelic Union been worthy of the name it bore, and of the cause which it pretended to defend, insuperable obstacles might have prevented the execution of the sentence; but it was hopeless for a power which was far from a match even for the Spanish troops in the Lower Palatinate, to contend against the united strength of the Emperor, Bavaria, and the League. The sentence of proscription pronounced upon the Elector soon detached the free cities from the Union; and the princes quickly followed their example. Fortunate in preserving their own dominions, they abandoned the Elector, their former chief, to the Emperor's mercy, renounced the Union, and vowed never to revive it again.
But while thus ingloriously the German princes deserted the unfortunate Frederick, and while Bohemia, Silesia, and Moravia submitted to the Emperor, a single man, a soldier of fortune, whose only treasure was his sword, Ernest Count Mansfeld, dared, in the Bohemian town of Pilsen, to defy the whole power of Austria. Left without assistance after the battle of Prague by the Elector, to whose service he had devoted himself, and even uncertain whether Frederick would thank him for his perseverance, he alone for some time held out against the imperialists, till the garrison, mutinying for want of pay, sold the town to the Emperor. Undismayed by this reverse, he immediately commenced new levies in the Upper Palatinate, and enlisted the disbanded troops of the Union. A new army of 20,000 men was soon assembled under his banners, the more formidable to the provinces which might be the object of its attack, because it must subsist by plunder. Uncertain where this swarm might light, the neighbouring bishops trembled for their rich possessions, which offered a tempting prey to its ravages. But, pressed by the Duke of Bavaria, who now entered the Upper Palatinate, Mansfeld was compelled to retire. Eluding, by a successful stratagem, the Bavarian general, Tilly, who was in pursuit of him, he suddenly appeared in the Lower Palatinate, and there wreaked upon the bishoprics of the Rhine the severities he had designed for those of Franconia. While the imperial and Bavarian allies thus overran Bohemia, the Spanish general, Spinola, had penetrated with a numerous army from the Netherlands into the Lower Palatinate, which, however, the pacification of Ulm permitted the Union to defend. But their measures were so badly concerted, that one place after another fell into the hands of the Spaniards; and at last, when the Union broke up, the greater part of the country was in the possession of Spain. The Spanish general, Corduba, who commanded these troops after the recall of Spinola, hastily raised the siege of Frankenthal, when Mansfeld entered the Lower Palatinate. But instead of driving the Spaniards out of this province, he hastened across the Rhine to secure for his needy troops shelter and subsistence in Alsace. The open countries on which this swarm of maurauders threw themselves were converted into frightful deserts, and only by enormous contributions could the cities purchase an exemption from plunder. Reinforced by this expedition, Mansfeld again appeared on the Rhine to cover the Lower Palatinate.
