Changing their intentions, they left two thousand horse in front of his camp, making believe that they intended to attack him, then marched with all haste to the Lech and advanced against Landsberg, which they took by assault.

In the city were the principal magazines of the Imperialist army, and the allies, finding sufficient provisions there to last for six months, encamped round the city and decided to winter there unless attacked, in the meantime sending out bodies of cavalry, which levied contributions up to the very gates of Munich.

Leopold, thus deprived of his magazines, retired with the Austrian contingent, and the Bavarians returned home.
The Duke of Bavaria, finding that his whole dominions would be captured unless he made terms, therefore opened negotiations, and on the 14th of March, 1646, peace was signed, the terms being that he should separate himself entirely from the empire and deliver five of his fortresses to the allies, who would thus, should he again break his word, have means of access into his dominions.

The allied forces were now in a condition to march upon Vienna.

They had during the winter plundered a large portion of Bavaria; they and their horses had recovered from their fatigue, and their force now amounted to fourteen thousand foot and twenty thousand horse.
