The first thing was to crush military opposition. At the end of March the Swedes were again in the field. On the 31st Gustavus entered Nuremberg in triumph and received an enthusiastic welcome. On April 5th he captured Donauwörth, on the 14th he found Tilly entrenched behind the Lech, forced the passage of the river, stormed the enemies’ position, and drove back the old marshal to Ingolstadt wounded to death. Bavaria was at his feet. Side by side with the Elector Palatine he rode into Munich on the 7th of May. There was now no enemy left to be dealt with except the Emperor, and the dominions of the Hapsburgs were still in far too disorganised a state to be able to offer much opposition. Even the Saxons had marched unopposed into Bohemia, and when Gustavus was celebrating his triumph with the winter-king at Munich, John George, who had done more than any one else to oust Frederick from Bohemia, was keeping high festival himself at Prague. [Sidenote: =Wallenstein appealed to by the Emperor.=] It was not for long. There was but one man in all wide Europe who could save Ferdinand from the storm just breaking upon his head, for there was but one capable of drawing to himself and binding together into an organised army the soldiers of fortune who were scattered all over the civilised world. In December, Eggenberg, Ferdinand’s most trusted counsellor, had been sent to Wallenstein to ask him to forgive the past and strike one more blow for the defence of the House of Austria. Wallenstein eagerly seized the opportunity, for circumstances had played singularly into his hand. The victories of Gustavus had drawn the teeth of Maximilian and the League. The necessities of the Emperor must force him to agree to whatever terms were demanded. The long wished for moment had arrived when he at the head of an army, wholly his own, owing no allegiance to the Emperor, might become the dictator of Germany, and, ousting from her soil all foreigners except himself, might impose peace upon Germany on the basis of religious toleration. [Sidenote: =His terms.=] The terms which he exacted from the Emperor forbid any doubt as to his intentions. No army was to be allowed in the Empire except under his command, he alone was to have the right of pardoning offenders and confiscating lands. [Sidenote: =Appointed dictator.=] The Edict of Restitution was to be withdrawn. In other words, he was to be the military and political dictator of Germany. The terms were accepted, his standard raised. From Italy, Scotland, Ireland, as well as from every part of Germany, flocked to him men eager for distinction and more eager for plunder, without distinction of nationality and without distinction of religion. In May 1632, his organisation was completed. [Sidenote: =His plan of campaign.=] Falling suddenly upon the Saxons at Prague he drove them headlong out of Bohemia, then turning swiftly to the left directed his main army upon the rich and Protestant Nuremberg, while Pappenheim
