foe, made the most formidable preparations for the strife, and soon took
the field with an army which he supposed would certainly triumph over
any force which Rhodolph could raise. He even succeeded in drawing Henry

German allies, and that they could present no effectual resistance to so
powerful an army as was approaching, and terrified in view of a siege,
and the capture of the city by storm, urged a capitulation, and even
