and the Imperialists were, in a short time, totally driven
from Saxony. The united army again divided: the Saxons marched towards
Lusatia and Silesia, to act in conjunction with Count Thurn against the
Austrians in that quarter; a part of the Swedish army was led by the
Duke of Weimar into Franconia, and the other by George, Duke of
Brunswick, into Westphalia and Lower Saxony.

The conquests on the Lech and the Danube, during Gustavus's expedition
into Saxony, had been maintained by the Palatine of Birkenfeld, and the
Swedish General Banner, against the Bavarians; but unable to hold their
ground against the victorious progress of the latter, supported as they
were by the bravery and military experience of the Imperial General
Altringer, they were under the necessity of summoning the Swedish
General Horn to their assistance, from Alsace. This experienced general
having captured the towns of Benfeld, Schlettstadt, Colmar, and Hagenau,
committed the defence of them to the Rhinegrave Otto Louis, and hastily
crossed the Rhine to form a junction with Banner's army. But although
the combined force amounted to more than 16,000, they could not prevent
the enemy from obtaining a strong position on the Swabian frontier,
taking Kempten, and being joined by seven regiments from Bohemia. In
order to retain the command of the important banks of the Lech and the
Danube, they were under the necessity of recalling the Rhinegrave Otto
Louis from Alsace, where he had, after the departure of Horn, found it
difficult to defend himself against the exasperated peasantry. With his
army, he was now summoned to strengthen the army on the Danube; and as
even this reinforcement was insufficient, Duke Bernard of Weimar was
earnestly pressed to turn his arms into this quarter.

Duke Bernard, soon after the opening of the campaign of 1633, had made
himself master of the town and territory of Bamberg, and was now
threatening Wurtzburg. But on receiving the summons of General Horn,
without delay he began his march towards the Danube, defeated on his way
a Bavarian army under John de Werth, and joined the Swedes near
Donauwerth. This numerous force, commanded by excellent generals, now
threatened Bavaria with a fearful inroad. The bishopric of Eichstadt
was completely overrun, and Ingoldstadt was on the point of being
delivered up by treachery to the Swedes. Altringer, fettered in his
movements by the express order of the Duke of Friedland, and left
