Meanwhile, the war along the Rhine assumed more and more the savage character that made it so destructive to the land. Mansfeld, driven from the Palatinate, supported his ferocious troops almost entirely by plundering. Tilly, the chief general of the Catholic League, followed similar tactics, and, wherever they passed, the land lay ruined behind them. Some of the lesser Protestant princes joined Mansfeld, but Tilly proved a great military leader, and his opponents were slowly crowded back into Northern Germany. The Emperor forced his religion upon the Rhine districts, as he had upon Bohemia and Austria. The Protestant world at last began to take alarm. Both England and Holland lent Mansfeld support. The King of Denmark, drawing as many of the Protestant German princes as possible to his side, joined vigorously in the contest.
This Danish struggle may be considered the third period of the war. It lasted from about 1625 to 1629, and introduces one of the two most remarkable men of the period.
Albert of Waldstein, or Wallenstein, as he is generally called, was a native of Bohemia, who joined the Catholics, and won military fame and experience fighting on the imperial side in the Bohemian war. He acquired vast wealth through marriage and the purchase of the confiscated Protestant estates. Proving a remarkably capable financial manager, he was soon the richest subject in the empire, and was created Duke of Friedland, a district of Bohemia.
All of these successes were to Wallenstein mere preliminary steps to an even more boundless ambition. He studied the political outlook, and his keen eye saw the possibility of vastly expanding Mansfeld's barbaric system of supporting his soldiers by plunder. The Emperor Ferdinand had but few troops of his own, and they were needed for quelling rebellion within his personal domains. For carrying on the war along the Rhine, he was entirely dependent upon the princes of the Catholic League and their army under Tilly.
Wallenstein now came forward and offered to supply the Emperor with a powerful imperial army which should not cost him a penny. This offer, coming from a mere private gentleman, sounded absurd; and for a time Wallenstein was put aside with contemptuous laughter. At last the Emperor told him, if he thought he could raise as many as ten thousand men, to go ahead. "If I have only ten thousand," said Wallenstein, "we must accept what people choose to give us. If I have thirty thousand, we can take what we like."
The answer makes plain his whole system. His troops supported and paid themselves at the expense of the neighborhood where they were quartered. If it was a district which upheld the Emperor they took "contributions to the necessity of the empire." If the land opposed him, no polite words were needed to justify its pillage. Within three months Wallenstein had nearly fifty thousand men under his standard, drawn to him by the tempting offers of plunder that his agents held out. If the war had been terrible before, imagine the awful phase it now assumed, and the blighting curse that fell upon unhappy Germany!
Modern justice can find little to choose thereafter between the methods of the opposing armies. We speak, therefore, only of the martial genius which Wallenstein displayed. He completely outmanœuvred Mansfeld, defeated him, and drove him to flight and death. Then Wallenstein and Tilly proceeded to destroy the high military reputation of the Danish King. He was overcome in battle after battle, and his land so completely devastated that he prayed for peace on any terms.
Peace seemed indeed at hand. The remaining Lutheran states of Saxony and Brandenburg, which had been neutral and were as yet almost unharmed, dared not interfere. The Emperor Ferdinand might have arranged everything as he chose had he used his power with moderation. But his hopes had grown with his fortunes, and he seems to have planned the establishment of such an absolute power over Germany as had been the aim of his ancestor, Charles V. Ferdinand passed laws and gave decrees, without any pretence of calling a council or seeking the approval of the princes. His general, Wallenstein, was given one of the conquered states as his dukedom; and Wallenstein declared openly that his master had no further need of councils; the time had come for Germany to be governed as were France and Spain.
The Catholic princes, with Maximilian of Bavaria at their head, became frightened by the giant they themselves had created, and began to take measures for their own preservation. They demanded that Wallenstein be removed from his command. The Emperor, perhaps himself afraid of his too powerful general, finally consented.
There still remained, however, the serious question whether Wallenstein would accept his dismissal. His huge and ever-growing army was absolutely under his control. His influence over the troops was extraordinary. A firm believer in astrology, he asserted that the stars promised him certain success, and his followers believed him. Tall and thin, dark and solemn, silent and grim, wearing a scarlet cloak and a long, blood-red feather in his hat, he was declared by popular superstition to be in league with the devil, invulnerable and unconquerable. No evil act of his soldiery did he ever rebuke. Only two things he demanded of them—absolute obedience and unshaken daring. The man who flinched or disobeyed was executed on the instant. Otherwise the marauders might desecrate God's earth with whatsoever hideous crimes they would. His troops laughed at the idea of being Catholics or Protestants, Germans or Bohemians; they were "Wallensteiners" and nothing else.
