On the first advance of the Swedish cavalry a panic seized them, and they were driven without difficulty from their cantonments in Wurtzburg;the defeat of a few regiments occasioned a general rout, and the scattered remnant sought a covert from the Swedish valour in the towns beyond the Rhine. Loaded with shame and ridicule, the duke hurried home by Strasburg, too fortunate in escaping, by a submissive written apology, the indignation of his conqueror, who had first beaten him out of the field, and then called upon him to account for his hostilities. It is related upon this occasion that, in a village on the Rhine a peasant struck the horse of the duke as he rode past, exclaiming, "Haste, Sir, you must go quicker to escape the great King of Sweden!"The example of his neighbours' misfortunes had taught the Bishop of Bamberg prudence. To avert the plundering of his territories, he made offers of peace, though these were intended only to delay the king's course till the arrival of assistance. Gustavus Adolphus, too honourable himself to suspect dishonesty in another, readily accepted the bishop's proposals, and named the conditions on which he was willing to save his territories from hostile treatment. He was the more inclined to peace, as he had no time to lose in the conquest of Bamberg, and his other designs called him to the Rhine. The rapidity with which he followed up these plans, cost him the loss of those pecuniary supplies which, by a longer residence in Franconia, he might easily have extorted from the weak and terrified bishop. This artful prelate broke off the negotiation the instant the storm of war passed away from his own territories. No sooner had Gustavus marched onwards than he threw himself under the protection of Tilly, and received the troops of the Emperor into the very towns and fortresses, which shortly before he had shown himself ready to open to the Swedes. By this stratagem, however, he only delayed for a brief interval the ruin of his bishopric.
A Swedish general who had been left in Franconia, undertook to punish the perfidy of the bishop; and the ecclesiastical territory became the seat of war, and was ravaged alike by friends and foes.
The formidable presence of the Imperialists had hitherto been a check upon the Franconian States; but their retreat, and the humane conduct of the Swedish king, emboldened the nobility and other inhabitants of this circle to declare in his favour. Nuremberg joyfully committed itself to his protection; and the Franconian nobles were won to his cause by flattering proclamations, in which he condescended to apologize for his hostile appearance in the dominions. The fertility of Franconia, and the rigorous honesty of the Swedish soldiers in their dealings with the inhabitants, brought abundance to the camp of the king.
The high esteem which the nobility of the circle felt for Gustavus, the respect and admiration with which they regarded his brilliant exploits, the promises of rich booty which the service of this monarch held out, greatly facilitated the recruiting of his troops; a step which was made necessary by detaching so many garrisons from the main body.
At the sound of his drums, recruits flocked to his standard from all quarters.
The king had scarcely spent more time in conquering Franconia, than he would have required to cross it. He now left behind him Gustavus Horn, one of his best generals, with a force of 8,000 men, to complete and retain his conquest. He himself with his main army, reinforced by the late recruits, hastened towards the Rhine in order to secure this frontier of the empire from the Spaniards;to disarm the ecclesiastical electors, and to obtain from their fertile territories new resources for the prosecution of the war.
Following the course of the Maine, he subjected, in the course of his march, Seligenstadt, Aschaffenburg, Steinheim, the whole territory on both sides of the river. The imperial garrisons seldom awaited his approach, and never attempted resistance. In the meanwhile one of his colonels had been fortunate enough to take by surprise the town and citadel of Hanau, for whose preservation Tilly had shown such anxiety. Eager to be free of the oppressive burden of the Imperialists, the Count of Hanau gladly placed himself under the milder yoke of the King of Sweden.
Gustavus Adolphus now turned his whole attention to Frankfort, for it was his constant maxim to cover his rear by the friendship and possession of the more important towns. Frankfort was among the free cities which, even from Saxony, he had endeavoured to prepare for his reception; and he now called upon it, by a summons from Offenbach, to allow him a free passage, and to admit a Swedish garrison.
Willingly would this city have dispensed with the necessity of choosing between the King of Sweden and the Emperor; for, whatever party they might embrace, the inhabitants had a like reason to fear for their privileges and trade. The Emperor's vengeance would certainly fall heavily upon them, if they were in a hurry to submit to the King of Sweden, and afterwards he should prove unable to protect his adherents in Germany. But still more ruinous for them would be the displeasure of an irresistible conqueror, who, with a formidable army, was already before their gates, and who might punish their opposition by the ruin of their commerce and prosperity.
In vain did their deputies plead the danger which menaced their fairs, their privileges, perhaps their constitution itself, if, by espousing the party of the Swedes, they were to incur the Emperor's displeasure.
