Elector of
Bavaria silently undertook the same task with the Emperor his ally, and
determined, by prudently dealing out his aid, to hold the fate of
Austria in his own hands. And now that the power of the Emperor
threatened once more to attain a dangerous superiority, Maximilian at
once ceased to pursue the Swedes. He was also afraid of reprisals from
France, who had threatened to direct Turenne's whole force against him
if he allowed his troops to cross the Weser.

Melander, prevented by the Bavarians from further pursuing Wrangel,
crossed by Jena and Erfurt into Hesse, and now appeared as a dangerous
enemy in the country which he had formerly defended. If it was the
desire of revenge upon his former sovereign, which led him to choose
Hesse for the scene of his ravage, he certainly had his full
gratification. Under this scourge, the miseries of that unfortunate
state reached their height. But he had soon reason to regret that, in
the choice of his quarters, he had listened to the dictates of revenge
rather than of prudence. In this exhausted country, his army was
oppressed by want, while Wrangel was recruiting his strength, and
remounting his cavalry in Lunenburg. Too weak to maintain his wretched
quarters against the Swedish general, when he opened the campaign in the
winter of 1648, and marched against Hesse, he was obliged to retire with
disgrace, and take refuge on the banks of the Danube.

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
