All Protestant Germany hailed Gustavus as the liberator. John George, the Swedish general Horn and the Swedish chancellor Oxenstierna united in advising Gustavus to march straight upon.
Vienna. Richelieu was of the same mind. But Gustavus de liberately chose to move into South Germany, there to organize the cities and the princes in a new and stronger Protestant Union the Corpus Evangelicorum, and to place himself in a country full of resources whence he could strike out against the emperor, Tilly and the Rhine Spaniards in turn. The Swedish army pushed on to Mainz, where it wintered in luxury. The Palatinate was re organized under Swedish officials and the reformed religion estab lished again. In March 1632 the campaign was resumed. Nurem berg and Donauworth welcomed Gustavus. Tilly's army, reorgan ized for the defence of Bavaria, stood to fight on the Lech, but the passage was forced (April 4-14) and Tilly himself was mor tally wounded. Augsburg, Munich and all the country south of the Danube were occupied without resistance. At the same time John George's Saxons, advancing into Bohemia, entered Prague without firing a shot.
Swedish king had now to meet Wallenstein's new army of 6o,000, composed of the men immortalized by Schiller's play, excellent in war and in plundering, destitute of all home and national ties, and owning allegiance to its general alone. While Gustavus in Fran conia was endeavouring with little success to consolidate his Cor pus Evangelicorum Wallenstein came upon the scene. Gustavus offered him battle. But as in 1625 Wallenstein would risk no battle until his army had gained confidence. He entrenched him self near Fiirth, while Gustavus camped his army about Nurem berg and a contest of endurance ensued. Wallenstein, aided by his superiority in irregular cavalry, was able to starve for three days longer than the king, and at last Gustavus furiously attacked the entrenchments (battle of the Alte Veste, Aug. 24–Sept. 3, 1632) and was repulsed with heavy losses. Thereupon he retired, endeavouring in vain to tempt Wallenstein out of his stronghold by making his retreat openly and within striking distance of the imperialists. Wallenstein had other views than simple military success. Instead of following Gustavus he marched into Saxony, his army plundering and burning even more thoroughly than usual in order to force the Saxons into peace. Gustavus followed with the swiftness that was peculiar to the Swedish system, and concentrated at Erfurt when Wallenstein had scarcely mastered Leipzig. But it was now late in the season, and Wallenstein hoped to spin out the few remaining weeks of the campaign in an en trenched position. Gustavus, without waiting for Arnim's Saxons to join him, suddenly moved forward, and on Nov. 6-16 the battle of Liitzen (q.v.) was fought, a battle as fierce even as Breitenfeld. Gustavus was slain, but Wallenstein's army was driven from the field.
