mounted to nearly 40,000 men. His progress through Franconia was
uninterrupted; for Tilly, far too weak to encounter an enemy so superior
in numbers, had retreated, by rapid marches, towards the Danube.
Bohemia and Bavaria were now equally near to the king, and, uncertain
whither his victorious course might be directed, Maximilian could form
no immediate resolution. The choice of the king, and the fate of both
provinces, now depended on the road that should be left open to Count
Tilly. It was dangerous, during the approach of so formidable an enemy,
to leave Bavaria undefended, in order to protect Austria; still more
dangerous, by receiving Tilly into Bavaria, to draw thither the enemy
also, and to render it the seat of a destructive war. The cares of the
sovereign finally overcame the scruples of the statesman, and Tilly
received orders, at all hazards, to cover the frontiers of Bavaria with
his army.

Nuremberg received with triumphant joy the protector of the Protestant
religion and German freedom, and the enthusiasm of the citizens
expressed itself on his arrival in loud transports of admiration and
joy. Even Gustavus could not contain his astonishment, to see himself

completed the impression produced by his glorious exploits, and the
condescension with which he received the congratulations of this free
city won all hearts. He now confirmed the alliance he had concluded
with it on the shores of the Baltic, and excited the citizens to zealous
activity and fraternal unity against the common enemy. After a short
stay in Nuremberg, he followed his army to the Danube, and appeared
unexpectedly before the frontier town of Donauwerth. A numerous
Bavarian garrison defended the place; and their commander, Rodolph
Maximilian, Duke of Saxe Lauenburg, showed at first a resolute
determination to defend it till the arrival of Tilly. But the vigour
with which Gustavus Adolphus prosecuted the siege, soon compelled him to
take measures for a speedy and secure retreat, which amidst a tremendous
fire from the Swedish artillery he successfully executed.

The conquest of Donauwerth opened to the king the further side of the
Danube, and now the small river Lech alone separated him from Bavaria.
The immediate danger of his dominions aroused all Maximilian's activity;
and however little he had hither
