Wallenstein fulfilled his promises, and raised in an incredibly short time an immense army, composed of outlaws and robbers and adventurers from all nations. He advanced rapidly against the allied Protestant forces, levying enormous contributions wherever he appeared; as imperious to friends as to foes, mistrusted and feared by both, yet supremely indifferent to praise or censure; resting on the power of brute force and his ability to enrich his soldiers. Possessing a fine military genius, unbounded means, and unscrupulous rapacity, and assisted by such generals as Tilly, Pappenheim, and Piccolomini, seconded by Maximilian, Duke of Bavaria, he soon reduced his enemies to despair. The King of Denmark was unequal to the contest, and sued for peace. The Elector Frederic again became a fugitive, the Duke of Brunswick was killed, and the intrepid Mansfeld died. The Electors of Saxony and Brandenburg, the natural defenders of Protestantism and the leading princes of the league, were awed into an abject neutrality. The old protectors of Lutheranism were timid and despairing. The monarchs of Europe trembled. Germany lay prostrate and bleeding. Christendom stood aghast at the greatness of the calamities which afflicted Germany and threatened neighboring nations. But the Emperor at Vienna was overjoyed, and swelled with arrogance and triumph. He divided among the members of his imperial house the rich benefices of the Church, and bestowed upon his victorious general the revenues of provinces. He now resolved to pursue the King of Denmark into his remotest territories, to dethrone the King of Sweden, to give away the crown of Poland, to aid the Spaniards in the recovery of the United Provinces, to exterminate the Protestant religion, to subvert the liberties of the German nations, and reign as a terrible incarnation of imperial tyranny. He would even revive the dreams of Charlemagne and Charles V., and make Vienna the centre of that power which once emanated from Borne. He would ally himself more strongly with the Pope, and extend the double tyranny of priests and kings over the whole continent of Europe. Fines, imprisonments, tortures, banishments, and executions were now added to the desolations which one hundred and fifty thousand soldiers inflicted on villages and cities that had been for generations increasing in wealth and prosperity. In that dark hour of calamity and fears, Providence raised up a greater hero than Wallenstein, a noble protector and intrepid deliverer, even Gustavus Adolphus, King of Sweden; and the third act of the political tragedy opens with his brilliant career.
