Travelling by different routes in two columns the army marched to Wurtzburg, the capital of Franconia, a rich and populous city, the Imperialist garrison having withdrawn to the strong castle of Marienburg, on a lofty eminence overlooking the town, and only separated from it by the river Maine. The cathedral at Wurtzburg is dedicated to a Scottish saint, St. Kilian, a bishop who with two priests came from Scotland in the year 688 to convert the heathen of Franconia. They baptized many at Wurtzburg, among them Gospert, the duke of that country. This leader was married to Geilana, the widow of his brother; and Kilian urging upon him that such a marriage was contrary to the laws of the Christian church, the duke promised to separate from her. Geilana had not, like her lord, accepted Christianity, and, furious at this interference of Kilian, she seized the opportunity when the latter had gone with his followers on an expedition against the pagan Saxons to have Kilian and his two companions murdered.
