France had once more disappointed the expectations of Sweden; and the army of Turenne, disregarding the remonstrances of Wrangel, had remained upon the Rhine. The Swedish leader revenged himself, by drawing into his service the cavalry of Weimar, which had abandoned the standard of France, though, by this step, he farther increased the jealousy of that power. Turenne received permission to join the Swedes; and the last campaign of this eventful war was now opened by the united armies. Driving Melander before them along the Danube, they threw supplies into Egra, which was besieged by the Imperialists, and defeated the Imperial and Bavarian armies on the Danube, which ventured to oppose them at Susmarshausen, where Melander was mortally wounded. After this overthrow, the Bavarian general, Gronsfeld, placed himself on the farther side of the Lech, in order to guard Bavaria from the enemy. But Gronsfeld was not more fortunate than Tilly, who, in this same position, had sacrificed his life for Bavaria. Wrangel and Turenne chose the same spot for passing the river, which was so gloriously marked by the victory of Gustavus Adolphus, and accomplished it by the same means, too, which had favoured their predecessor. Bavaria was now a second time overrun, and the breach of the truce punished by the severest treatment of its inhabitants. Maximilian sought shelter in Salzburgh, while the Swedes crossed the Iser, and forced their way as far as the Inn. A violent and continued rain, which in a few days swelled this inconsiderable stream into a broad river, saved Austria once more from the threatened danger. The enemy ten times attempted to form a bridge of boats over the Inn, and as often it was destroyed by the current. Never, during the whole course of the war, had the Imperialists been in so great consternation as at present, when the enemy were in the centre of Bavaria, and when they had no longer a general left who could be matched against a Turenne, a Wrangel, and a Koenigsmark. At last the brave Piccolomini arrived from the Netherlands, to assume the command of the feeble wreck of the Imperialists. By their own ravages in Bohemia, the allies had rendered their subsistence in that country impracticable, and were at last driven by scarcity to retreat into the Upper Palatinate, where the news of the peace put a period to their activity.
