Tilly would soon rally his fugitives, and, reinforced by the numerous Imperialist garrisons from the towns, would be able to overrun North Germany in his absence, and to force the Saxons to join him even if the elector were unwilling to do so. Thus the little Swedish force would be isolated in the heart of Germany; and should Ferdinand abandon Vienna at his approach and altogether refuse to treat with him—which his obstinacy upon a former occasion when in the very hands of his enemy rendered probable—the Swedes would find themselves in a desperate position, isolated and alone in the midst of enemies.

There was another consideration. An Imperialist diet was at that moment sitting at Frankfort, and Ferdinand was using all his influence to compel the various princes and representatives of the free cities to submit to him. It was of the utmost importance that Gustavus should strengthen his friends and overawe the waverers by the approach of his army. Hitherto Franconia and the Rhine provinces had been entirely in the hands of the Imperialists, and it was needful that a counterbalancing influence should be exerted. These considerations induced Gustavus to abandon the tempting idea of a march upon Vienna. The Elector of Saxony was charged with carrying the war into Silesia and Bohemia, the Electors of Hesse and Hesse-Cassel were to maintain Lower Saxony and Westphalia, and the Swedish army turned its face towards the Rhine.

On the 20th of September it arrived before Erfurt, an important fortified town on the Gera, which surrendered at discretion. Gustavus granted the inhabitants, who were for the most part Catholics, the free exercise of their religion, and nominated the Duke of Saxe-Weimar to be governor of the district and of the province of Thuringen, and the Count of Lowenstein to be commander of the garrison, which consisted of Colonel Foulis's Scottish regiment, 1500 strong.

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the army marched to Wurtzburg, the capital of Franconia, a rich and populous city, the Imperialist garrison having withdrawn to the strong castle of Marienburg, on a lofty eminence overlooking the town, and only separated from it by the river Maine.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.

The cathedral was naturally an object of interest to the Scotch soldiers in the time of Gustavus, and there was an animated argument in the quarters of the officers of Munro's regiment on the night of their arrival as to whether St. Kilian had done well or otherwise in insisting upon his new convert repudiating his wife. The general opinion, however, was against the saint, the colonel summing up the question.

“In my opinion,” he said, “Kilian was a fool. Here was no less a matter at stake than the conversion of a whole nation, or at least of a great tribe of heathens, and Kilian imperilled it all on a question of minor importance; for in the first place, the Church of Rome has always held that the pope could grant permission for marriage within interdicted degrees; in the second place, the marriage had taken place before the conversion of the duke to Christianity, and they were therefore innocently and without thought of harm bona fide man and wife. Lastly, the Church of Rome is opposed to divorce; and Kilian might in any case have put up with this small sin, if sin it were, for the sake of saving the souls of thousands of pagans. My opinion is that St. Kilian richly deserved the fate which befell him. And now to a subject much more interesting to us—viz, the capture of Marienburg.

“I tell you, my friends, it is going to be a warm business; the castle is considered impregnable, and is strong by nature as well as art, and Captain Keller is said to be a stout and brave soldier. He has 1000 men in the garrison, and all the monks who were in the town have gone up and turned soldiers. But if the task is a hard one the reward will be rich; for as the Imperialists believe the place cannot be taken, the treasures of all the country round are stored up there. And I can tell you more, in the cellars are sixty gigantic tuns of stone, the smallest of which holds twenty-five wagon loads of wine, and they say some of it is a hundred years old. With glory and treasure and good wine to be won we will outdo ourselves tomorrow; and you may be sure that the brunt of the affair will fall upon the Scots.”

“Well, there is one satisfaction,” said Nigel Graheme—who after Leipzig had been promoted to the rank of major—“if we get the lion's share of the fighting, we shall have the lion's share of the plunder and wine.”

“For shame, Graheme! You say nothing of the glory.”

“Ah! well,” Graheme laughed, “we have already had so large share of that, that I for one could do without winning any more just at present. It's a dear commodity to purchase, and neither fills our belly nor our pockets.”
