Ferdinand had perceived too late the errors of that policy, which reduced the Elector of Saxony to extremities, and forcibly driven this powerful monarch into an alliance with Sweden. By moderation, equally ill-timed, he now wished to repair if possible the consequences of his haughtiness; and thus committed a second error in endeavouring to repair the first. To deprive his enemy of so powerful an ally, he had opened, through the intervention of Spain, a negociation with the Elector; and in order to facilitate an accommodation, Tiefenbach was ordered immediately to retire from Saxony. But these concessions of the Emperor, far from producing the desired effect, only revealed to the Elector the embarrassment of his adversary and his own importance, and emboldened him the more to prosecute the advantages he had already obtained. How could he, moreover, without becoming chargeable with the most shameful ingratitude, abandon an ally to whom he had given the most solemn assurances of fidelity, and to whom he was indebted for the preservation of his dominions, and even of his Electoral dignity? The Saxon army, now relieved from the necessity of marching into Lusatia, advanced towards Bohemia, where a combination of favourable circumstances seemed to ensure them an easy victory. In this kingdom, the first scene of this fatal war, the flames of dissension still smouldered beneath the ashes, while the discontent of the inhabitants was fomented by daily acts of oppression and tyranny. On every side, this unfortunate country showed signs of a mournful change. Whole districts had changed their proprietors, and groaned under the hated yoke of Roman Catholic masters, whom the favour of the Emperor and the Jesuits had enriched with the plunder and possessions of the exiled Protestants. Others, taking advantage themselves of the general distress, had purchased, at a low rate, the confiscated estates. The blood of the most eminent champions of liberty had been shed upon the scaffold; and such as by a timely flight avoided that fate, were wandering in misery far from their native land, while the obsequious slaves of despotism enjoyed their patrimony. Still more insupportable than the oppression of these petty tyrants, was the restraint of conscience which was imposed without distinction on all the Protestants of that kingdom. No external danger, no opposition on the part of the nation, however steadfast, not even the fearful lessons of past experience could check in the Jesuits the rage of proselytism; where fair means were ineffectual, recourse was had to military force to bring the deluded wanderers within the pale of the church. The inhabitants of Joachimsthal, on the frontiers between Bohemia and Meissen, were the chief sufferers from this violence. Two imperial commissaries, accompanied by as many Jesuits, and supported by fifteen musketeers, made their appearance in this peaceful valley to preach the gospel to the heretics.
