he Elector addressed the
most pressing entreaties to the Emperor and the Duke of Friedland to
assist him, were it only with 5,000 men. Seven messengers in succession
were despatched by Ferdinand to Wallenstein, who promised immediate
succours, and even announced to the Elector the near advance of 12,000
men under Gallas; but at the same time forbade that general, under pain
of death, to march. Meanwhile the Bavarian commandant of Ratisbon, in
the hope of speedy assistance, made the best preparations for defence,
armed the Roman Catholic peasants, disarmed and carefully watched the

The possession of Ratisbon, enlarged the projects of the duke, and

and the river Iser, while his rear was covered by no tenable position,
and no entrenchment could be made in the frozen ground, and threatened
by the whole force of Wallenstein, who had at last resolved to march to
the Danube, by a timely retreat he escaped the danger of being cut off
from Ratisbon, and surrounded by the enemy. He hastened across the Iser
to the Danube, to defend the conquests he had made in the Upper
Palatinate against Wallenstein, and fully resolved not to decline a
