In a Diet held at Ratisbon, at which Ferdinand was present in person (in 1630), the necessity of taking some measures for the immediate restoration of a general peace to Germany, and for the removal of all grievances, was debated. The complaints of the Roman Catholics were scarcely less numerous than those of the Protestants, although Ferdinand had flattered himself that by the Edict of Restitution he had secured the members of the League, and its leader by the gift of the electoral dignity, and the cession of great part of the Palatinate. But the good understanding between the Emperor and the princes of the League had rapidly declined since the employment of Wallenstein. Accustomed to give law to Germany, and even to sway the Emperor's own destiny, the haughty Elector of Bavaria now at once saw himself supplanted by the imperial general, and with that of the League, his own importance completely undermined. Another had now stepped in to reap the fruits of his victories, and to bury his past services in oblivion. Wallenstein's imperious character, whose dearest triumph was in degrading the authority of the princes, and giving an odious latitude to that of the Emperor, tended not a little to augment the irritation of the Elector. Discontented with the Emperor, and distrustful of his intentions, he had entered into an alliance with France, which the other members of the League were suspected of favouring. A fear of the Emperor's plans of aggrandizement, and discontent with existing evils, had extinguished among them all feelings of gratitude. Wallenstein's exactions had become altogether intolerable. Brandenburg estimated its losses at twenty, Pomerania at ten, Hesse Cassel at seven millions of dollars, and the rest in proportion. The cry for redress was loud, urgent, and universal; all prejudices were hushed; Roman Catholics and Protestants were united on this point. The terrified Emperor was assailed on all sides by petitions against Wallenstein, and his ear filled with the most fearful descriptions of his outrages. Ferdinand was not naturally cruel. If not totally innocent of the atrocities which were practised in Germany under the shelter of his name, he was ignorant of their extent; and he was not long in yielding to the representation of the princes, and reduced his standing army by eighteen thousand cavalry. While this reduction took place, the Swedes were actively preparing an expedition into Germany, and the greater part of the disbanded Imperialists enlisted under their banners.
