e 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
in this city, which was the very centre of Germany, where he had never
expected to be able to penetrate. The noble appearance of his person,
completed the impression produced by his glorious exploits, and the
condescension with which he received the congratulations of this free

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

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 hitherto disturbed the enemy's progress to his
frontier, he now determined to dispute as resolutely the remainder of
their course. On the opposite bank of the Lech, near the small town of
Rain, Tilly occupied a strongly fortified camp, which, surrounded by
three rivers, bade defiance to all attack. All the bridges over the
Lech were destroyed; the whole course of the stream protected by strong
garrisons as far as Augsburg; and that town itself, which had long
betrayed its impatience to follow the example of Nuremberg a
