Meantime, the imperial generals, deficient both in troops and money,
found themselves reduced to the disagreeable alternative of losing sight
either of the King of Sweden, or of the Estates of the empire, since
with a divided force they were not a match for either. The movements of
the Protestants called their attention to the interior of the empire,
while the progress of the king in Brandenburg, by threatening the
hereditary possessions of Austria, required them to turn their arms to
that quarter. After the conquest of Frankfort, the king had advanced
upon Landsberg on the Warta, and Tilly, after a fruitless attempt to
relieve it, had again returned to Magdeburg, to prosecute with vigour
the siege of that town.

The rich archbishopric, of which Magdeburg was the capital, had long
been in the possession of princes of the house of Brandenburg, who
introduced the Protestant religion into the province. Christian
William, the last administrator, had, by his alliance with Denmark,
incurred the ban of the empire, on which account the chapter, to avoid
the Emperor's displeasure, had formally deposed him. In his place they

Saxony, whom the Emperor rejected, in order to confer the archbishopric
on his son Leopold. The Elector of Saxony complained ineffectually to
the imperial court; but Christian William of Brandenburg took more
active measures. Relying on the attachment of the magistracy and

chapter, the competition of two powerful rivals, and the Edict of

Scarcely had Christian William been informed of the landing of his
protector in Pomerania, than he entered Magdeburg in disguise.
Appearing suddenly in the town council, he reminded the magistrates of
the ravages which both town and country had suffered from the imperial
troops, of the pernicious designs of Ferdinand, and the danger of the
Protestant church. He then informed them that the moment of deliverance
was at hand, and that Gust
