His army amounted to 40,000 men, while to oppose him the allies had only 24,000. They nevertheless resolved to give him battle, and marched to Munsterberg, where he had formed an intrenched camp. But Wallenstein remained inactive for eight days; he then left his intrenchments, and marched slowly and with composure to the enemy's camp. But even after quitting his position, and when the enemy, emboldened by his past delay, manfully prepared to receive him, he declined the opportunity of fighting. The caution with which he avoided a battle was imputed to fear; but the well-established reputation of Wallenstein enabled him to despise this suspicion. The vanity of the allies allowed them not to see that he purposely saved them a defeat, because a victory at that time would not have served his own ends. To convince them of his superior power, and that his inactivity proceeded not from any fear of them, he put to death the commander of a castle that fell into his hands, because he had refused at once to surrender an untenable place.
For nine days, did the two armies remain within musket-shot of each other, when Count Terzky, from the camp of the Imperialists, appeared with a trumpeter in that of the allies, inviting General Arnheim to a conference. The purport was, that Wallenstein, notwithstanding his superiority, was willing to agree to a cessation of arms for six weeks. "He was come," he said, "to conclude a lasting peace with the Swedes, and with the princes of the empire, to pay the soldiers, and to satisfy every one. All this was in his power; and if the Austrian court hesitated to confirm his agreement, he would unite with the allies, and (as he privately whispered to Arnheim) hunt the Emperor to the devil." At the second conference, he expressed himself still more plainly to Count Thurn. "All the privileges of the Bohemians," he engaged, "should be confirmed anew, the exiles recalled and restored to their estates, and he himself would be the first to resign his share of them. The Jesuits, as the authors of all past grievances, should be banished, the Swedish crown indemnified by stated payments, and all the superfluous troops on both sides employed against the Turks." The last article explained the whole mystery. "If," he continued, "HE should obtain the crown of Bohemia, all the exiles would have reason to applaud his generosity; perfect toleration of religions should be established within the kingdom, the Palatine family be reinstated in its rights, and he would accept the Margraviate of Moravia as a compensation for Mecklenburg. The allied armies would then, under his command, advance upon Vienna, and sword in hand, compel the Emperor to ratify the treaty."
Thus was the veil at last removed from the schemes, over which he had brooded for years in mysterious silence. Every circumstance now convinced him that not a moment was to be lost in its execution. Nothing but a blind confidence in the good fortune and military genius of the Duke of Friedland, had induced the Emperor, in the face of the remonstrances of Bavaria and Spain, and at the expense of his own reputation, to confer upon this imperious leader such an unlimited command. But this belief in Wallenstein's being invincible, had been much weakened by his inaction, and almost entirely overthrown by the defeat at Lutzen. His enemies at the imperial court now renewed their intrigues; and the Emperor's disappointment at the failure of his hopes, procured for their remonstrances a favourable reception. Wallenstein's whole conduct was now reviewed with the most malicious criticism; his ambitious haughtiness, his disobedience to the Emperor's orders, were recalled to the recollection of that jealous prince, as well as the complaints of the Austrian subjects against his boundless oppression; his fidelity was questioned, and alarming hints thrown out as to his secret views. These insinuations, which the conduct of the duke seemed but too well to justify, failed not to make a deep impression on Ferdinand; but the step had been taken, and the great power with which Wallenstein had been invested, could not be taken from him without danger. Insensibly to diminish that power, was the only course that now remained, and, to effect this, it must in the first place be divided; but, above all, the Emperor's present dependence on the good will of his general put an end to. But even this right had been resigned in his engagement with Wallenstein, and the Emperor's own handwriting secured him against every attempt to unite another general with him in the command, or to exercise any immediate act of authority over the troops. As this disadvantageous contract could neither be kept nor broken, recourse was had to artifice. Wallenstein was Imperial Generalissimo in Germany, but his command extended no further, and he could not presume to exercise any authority over a foreign army. A Spanish army was accordingly raised in Milan, and marched into Germany under a Spanish general. Wallenstein now ceased to be indispensable because he was no longer supreme, and in case of necessity, the Emperor was now provided with the means of support even against him.
The duke quickly and deeply felt whence this blow came, and whither it was aimed. In vain did he protest against this violation of the compact, to the Cardinal Infante; the Italian army continued its march, and he was forced to detach General Altringer to join it with a reinforcement. He took care, indeed, so closely to fetter the latter, as to prevent the Italian army from acquiring any great reputation in Alsace and Swabia; but this bold step of the court awakened him from his security, and warned him of the approach of danger. That he might not a second time be deprived of his command, and lose the fruit of all his labours, he must accelerate the accomplishment of his long meditated designs. He secured the attachment of his troops by removing the doubtful officers, and by his liberality to the rest. He had sacrificed to the welfare of the army every other order in the state, every consideration of justice and humanity, and therefore he reckoned upon their gratitude. At the very moment when he meditated an unparalleled act of ingratitude against the author of his own good fortune, he founded all his hopes upon the gratitude which was due to himself.
The leaders of the Silesian armies had no authority from their principals to consent, on their own discretion, to such important proposals as those of Wallenstein, and they did not even feel themselves warranted in granting, for more than a fortnight, the cessation of hostilities which he demanded. Before the duke disclosed his designs to Sweden and Saxony, he had deemed it advisable to secure the sanction of France to his bold undertaking. For this purpose, a secret negociation had been carried on with the greatest possible caution and distrust, by Count Kinsky with Feuquieres, the French ambassador at Dresden, and had terminated according to his wishes. Feuquieres received orders from his court to promise every assistance on the part of France, and to offer the duke a considerable pecuniary aid in case of need.
But it was this excessive caution to secure himself on all sides, that led to his ruin. The French ambassador with astonishment discovered that a plan, which, more than any other, required secrecy, had been communicated to the Swedes and the Saxons. And yet it was generally known that the Saxon ministry was in the interests of the Emperor, and on the other hand, the conditions offered to the Swedes fell too far short of their expectations to be likely to be accepted. Feuquieres, therefore, could not believe that the duke could be serious in calculating upon the aid of the latter, and the silence of the former. He communicated accordingly his doubts and anxieties to the Swedish chancellor, who equally distrusted the views of Wallenstein, and disliked his plans. Although it was no secret to Oxenstiern, that the duke had formerly entered into a similar negociation with Gustavus Adolphus, he could not credit the possibility of inducing a whole army to revolt, and of his extravagant promises. So daring a design, and such imprudent conduct, seemed not to be consistent with the duke's reserved and suspicious temper, and he was the more inclined to consider the whole as the result of dissimulation and treachery, because he had less reason to doubt his prudence than his honesty.
