Gustavus Adolphus expressed to them his astonishment that, when the liberties of Germany and the Protestant religion were at stake, the citizens of Frankfort should talk of their annual fairs, and postpone for temporal interests the great cause of their country and their conscience. He had, he continued, in a menacing tone, found the keys of every town and fortress, from the Isle of Rugen to the Maine, and knew also where to find a key to Frankfort;the safety of Germany, and the ******* of the Protestant Church, were, he assured them, the sole objects of his invasion;conscious of the justice of his cause, he was determined not to allow any obstacle to impede his progress. "The inhabitants of Frankfort, he was well aware, wished to stretch out only a finger to him, but he must have the whole hand in order to have something to grasp."At the head of the army, he closely followed the deputies as they carried back his answer, and in order of battle awaited, near Saxenhausen, the decision of the council.
If Frankfort hesitated to submit to the Swedes, it was solely from fear of the Emperor; their own inclinations did not allow them a moment to doubt between the oppressor of Germany and its protector. The menacing preparations amidst which Gustavus Adolphus now compelled them to decide, would lessen the guilt of their revolt in the eyes of the Emperor, and by an appearance of compulsion justify the step which they willingly took.
The gates were therefore opened to the King of Sweden, who marched his army through this imperial town in magnificent procession, and in admirable order.
A garrison of 600 men was left in Saxenhausen; while the king himself advanced the same evening, with the rest of his army, against the town of Hoechst in Mentz, which surrendered to him before night.
While Gustavus was thus extending his conquests along the Maine, fortune crowned also the efforts of his generals and allies in the north of Germany. Rostock, Wismar, and Doemitz, the only strong places in the Duchy of Mecklenburg which still sighed under the yoke of the Imperialists, were recovered by their legitimate sovereign, the Duke John Albert, under the Swedish general, Achatius Tott.
In vain did the imperial general, Wolf Count von Mansfeld, endeavour to recover from the Swedes the territories of Halberstadt, of which they had taken possession immediately upon the victory of Leipzig;he was even compelled to leave Magdeburg itself in their hands.
The Swedish general, Banner, who with 8,000 men remained upon the Elbe, closely blockaded that city, and had defeated several imperial regiments which had been sent to its relief. Count Mansfeld defended it in person with great resolution; but his garrison being too weak to oppose for any length of time the numerous force of the besiegers, he was already about to surrender on conditions, when Pappenheim advanced to his assistance, and gave employment elsewhere to the Swedish arms.
Magdeburg, however, or rather the wretched huts that peeped out miserably from among the ruins of that once great town, was afterwards voluntarily abandoned by the Imperialists, and immediately taken possession of by the Swedes.
Even Lower Saxony, encouraged by the progress of the king, ventured to raise its head from the disasters of the unfortunate Danish war.
They held a congress at Hamburg, and resolved upon raising three regiments, which they hoped would be sufficient to free them from the oppressive garrisons of the Imperialists. The Bishop of Bremen, a relation of Gustavus Adolphus, was not content even with this;but assembled troops of his own, and terrified the unfortunate monks and priests of the neighbourhood, but was quickly compelled by the imperial general, Count Gronsfeld, to lay down his arms.
Even George, Duke of Lunenburg, formerly a colonel in the Emperor's service, embraced the party of Gustavus, for whom he raised several regiments, and by occupying the attention of the Imperialists in Lower Saxony, materially assisted him.
But more important service was rendered to the king by the Landgrave William of Hesse Cassel, whose victorious arms struck with terror the greater part of Westphalia and Lower Saxony, the bishopric of Fulda, and even the Electorate of Cologne. It has been already stated that immediately after the conclusion of the alliance between the Landgrave and Gustavus Adolphus at Werben, two imperial generals, Fugger and Altringer, were ordered by Tilly to march into Hesse, to punish the Landgrave for his revolt from the Emperor. But this prince had as firmly withstood the arms of his enemies, as his subjects had the proclamations of Tilly inciting them to rebellion, and the battle of Leipzig presently relieved him of their presence. He availed himself of their absence with courage and resolution; in a short time, Vach, Muenden and Hoexter surrendered to him, while his rapid advance alarmed the bishoprics of Fulda, Paderborn, and the ecclesiastical territories which bordered on Hesse.
The terrified states hastened by a speedy submission to set limits to his progress, and by considerable contributions to purchase exemption from plunder. After these successful enterprises, the Landgrave united his victorious army with that of Gustavus Adolphus, and concerted with him at Frankfort their future plan of operations.
In this city, a number of princes and ambassadors were assembled to congratulate Gustavus on his success, and either to conciliate his favour or to appease his indignation. Among them was the fugitive King of Bohemia, the Palatine Frederick V., who had hastened from Holland to throw himself into the arms of his avenger and protector. Gustavus gave him the unprofitable honour of greeting him as a crowned head, and endeavoured, by a respectful sympathy, to soften his sense of his misfortunes.
