The Thirty Years War — Volume 03

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. 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 freedom 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. But great as the advantages were, which Frederick had promised himself from the power and good fortune of his protector; and high as were the expectations he had built on his justice and magnanimity, the chance of this unfortunate prince's reinstatement in his kingdom was as distant as ever. The inactivity and contradictory politics of the English court had abated the zeal of Gustavus Adolphus, and an irritability which he could not always repress, made him on this occasion forget the glorious vocation of protector of the oppressed, in which, on his invasion of Germany, he had so loudly announced himself.

The terrors of the king's irresistible strength, and the near prospect of his vengeance, had also compelled George, Landgrave of Hesse Darmstadt, to a timely submission. His connection with the Emperor, and his indifference to the Protestant cause, were no secret to the king, but he was satisfied with laughing at so impotent an enemy. As the Landgrave knew his own strength and the political situation of Germany so little, as to offer himself as mediator between the contending parties, Gustavus used jestingly to call him the peacemaker. He was frequently heard to say, when at play he was winning from the Landgrave, "that the money afforded double satisfaction, as it was Imperial coin." To his affinity with the Elector of Saxony, whom Gustavus had cause to treat with forbearance, the Landgrave was indebted for the favourable terms he obtained from the king, who contented himself with the surrender of his fortress of Russelheim, and his promise of observing a strict neutrality during the war. The Counts of Westerwald and Wetteran also visited the King in Frankfort, to offer him their assistance against the Spaniards, and to conclude an alliance, which was afterwards of great service to him. The town of Frankfort itself had reason to rejoice at the presence of this monarch, who took their commerce under his protection, and by the most effectual measures restored the fairs, which had been greatly interrupted by the war.

The Swedish army was now reinforced by ten thousand Hessians, which the Landgrave of Casse commanded. Gustavus Adolphus had already invested Koenigstein; Kostheim and Floersheim surrendered after a short siege; he was in command of the Maine; and transports were preparing with all speed at Hoechst to carry his troops across the Rhine. These preparations filled the Elector of Mentz, Anselm Casimir, with consternation; and he no longer doubted but that the storm of war would next fall upon him. As a partisan of the Emperor, and one of the most active members of the League, he could expect no better treatment than his confederates, the Bishops of Wurtzburg and Bamberg, had already experienced. The situation of his territories upon the Rhine made it necessary for the enemy to secure them, while the fertility afforded an irresistible temptation to a necessitous army. Miscalculating his own strength and that of his adversaries, the Elector flattered himself that he was able to repel force by force, and weary out the valour of the Swedes by the strength of his fortresses. He ordered the fortifications of his capital to be repaired with all diligence, provided it with every necessary for sustaining a long siege, and received into the town a garrison of 2,000 Spaniards, under Don Philip de Sylva. To prevent the approach of the Swedish transports, he endeavoured to close the mouth of the Maine by driving piles, and sinking large heaps of stones and vessels. He himself, however, accompanied by the Bishop of Worms, and carrying with him his most precious effects, took refuge in Cologne, and abandoned his capital and territories to the rapacity of a tyrannical garrison. But these preparations, which bespoke less of true courage than of weak and overweening confidence, did not prevent the Swedes from marching against Mentz, and making serious preparations for an attack upon the city. While one body of their troops poured into the Rheingau, routed the Spaniards who remained there, and levied contributions on the inhabitants, another laid the Roman Catholic towns in Westerwald and Wetterau under similar contributions. The main army had encamped at Cassel, opposite Mentz; and Bernhard, Duke of Weimar, made himself master of the Maeusethurm and the Castle of Ehrenfels, on the other side of the Rhine. Gustavus was now actively preparing to cross the river, and to blockade the town on the land side, when the movements of Tilly in Franconia suddenly called him from the siege, and obtained for the Elector a short repose.

The danger of Nuremberg, which, during the absence of Gustavus Adolphus on the Rhine, Tilly had made a show of besieging, and, in the event of resistance, threatened with the cruel fate of Magdeburg, occasioned the king suddenly to retire from before Mentz. Lest he should expose himself a second time to the reproaches of Germany, and the disgrace of abandoning a confederate city to a ferocious enemy, he hastened to its relief by forced marches. On his arrival at Frankfort, however, he heard of its spirited resistance, and of the retreat of Tilly, and lost not a moment in prosecuting his designs against Mentz. Failing in an attempt to cross the Rhine at Cassel, under the cannon of the besieged, he directed his march towards the Bergstrasse, with a view of approaching the town from an opposite quarter. Here he quickly made himself master of all the places of importance, and at Stockstadt, between Gernsheim and Oppenheim, appeared a second time upon the banks of the Rhine. The whole of the Bergstrasse was abandoned by the Spaniards, who endeavoured obstinately to defend the other bank of the river. For this purpose, they had burned or sunk all the vessels in the neighbourhood, and arranged a formidable force on the banks, in case the king should attempt the passage at that place.

On this occasion, the king's impetuosity exposed him to great danger of falling into the hands of the enemy. In order to reconnoitre the opposite bank, he crossed the river in a small boat; he had scarcely landed when he was attacked by a party of Spanish horse, from whose hands he only saved himself by a precipitate retreat. Having at last, with the assistance of the neighbouring fishermen, succeeded in procuring a few transports, he despatched two of them across the river, bearing Count Brahe and 300 Swedes. Scarcely had this officer time to entrench himself on the opposite bank, when he was attacked by 14 squadrons of Spanish dragoons and cuirassiers. Superior as the enemy was in number, Count Brahe, with his small force, bravely defended himself, and gained time for the king to support him with fresh troops. The Spaniards at last retired with the loss of 600 men, some taking refuge in Oppenheim, and others in Mentz. A lion of marble on a high pillar, holding a naked sword in his paw, and a helmet on his head, was erected seventy years after the event, to point out to the traveller the spot where the immortal monarch crossed the great river of Germany.

Gustavus Adolphus now conveyed his artillery and the greater part of his troops over the river, and laid siege to Oppenheim, which, after a brave resistance, was, on the 8th December, 1631, carried by storm. Five hundred Spaniards, who had so courageously defended the place, fell indiscriminately a sacrifice to the fury of the Swedes. The crossing of the Rhine by Gustavus struck terror into the Spaniards and Lorrainers, who had thought themselves protected by the river from the vengeance of the Swedes. Rapid flight was now their only security; every place incapable of an effectual defence was immediately abandoned. After a long train of outrages on the defenceless citizens, the troops of Lorraine evacuated Worms, which, before their departure, they treated with wanton cruelty. The Spaniards hastened to shut themselves up in Frankenthal, where they hoped to defy the victorious arms of Gustavus Adolphus.

The king lost no time in prosecuting his designs against Mentz, into which the flower of the Spanish troops had thrown themselves. While he advanced on the left bank of the Rhine, the Landgrave of Hesse Cassel moved forward on the other, reducing several strong places on his march. The besieged Spaniards, though hemmed in on both sides, displayed at first a bold determination, and threw, for several days, a shower of bombs into the Swedish camp, which cost the king many of his bravest soldiers. But notwithstanding, the Swedes continually gained ground, and had at last advanced so close to the ditch that they prepared seriously for storming the place. The courage of the besieged now began to droop. They trembled before the furious impetuosity of the Swedish soldiers, of which Marienberg, in Wurtzburg, had afforded so fearful an example. The same dreadful fate awaited Mentz, if taken by storm; and the enemy might even be easily tempted to revenge the carnage of Magdeburg on this rich and magnificent residence of a Roman Catholic prince. To save the town, rather than their own lives, the Spanish garrison capitulated on the fourth day, and obtained from the magnanimity of Gustavus a safe conduct to Luxembourg; the greater part of them, however, following the example of many others, enlisted in the service of Sweden.

On the 13th December, 1631, the king made his entry into the conquered town, and fixed his quarters in the palace of the Elector. Eighty pieces of cannon fell into his hands, and the citizens were obliged to redeem their property from pillage, by a payment of 80,000 florins. The benefits of this redemption did not extend to the Jews and the clergy, who were obliged to make large and separate contributions for themselves. The library of the Elector was seized by the king as his share, and presented by him to his chancellor, Oxenstiern, who intended it for the Academy of Westerrah, but the vessel in which it was shipped to Sweden foundered at sea.

After the loss of Mentz, misfortune still pursued the Spaniards on the Rhine. Shortly before the capture of that city, the Landgrave of Hesse Cassel had taken Falkenstein and Reifenberg, and the fortress of Koningstein surrendered to the Hessians. The Rhinegrave, Otto Louis, one of the king's generals, defeated nine Spanish squadrons who were on their march for Frankenthal, and made himself master of the most important towns upon the Rhine, from Boppart to Bacharach. After the capture of the fortress of Braunfels, which was effected by the Count of Wetterau, with the co-operation of the Swedes, the Spaniards quickly lost every place in Wetterau, while in the Palatinate they retained few places besides Frankenthal. Landau and Kronweisenberg openly declared for the Swedes; Spires offered troops for the king's service; Manheim was gained through the prudence of the Duke Bernard of Weimar, and the negligence of its governor, who, for this misconduct, was tried before the council of war, at Heidelberg, and beheaded.

The king had protracted the campaign into the depth of winter, and the severity of the season was perhaps one cause of the advantage his soldiers gained over those of the enemy. But the exhausted troops now stood in need of the repose of winter quarters, which, after the surrender of Mentz, Gustavus assigned to them, in its neighbourhood. He himself employed the interval of inactivity in the field, which the season of the year enjoined, in arranging, with his chancellor, the affairs of his cabinet, in treating for a neutrality with some of his enemies, and adjusting some political disputes which had sprung up with a neighbouring ally. He chose the city of Mentz for his winter quarters, and the settlement of these state affairs, and showed a greater partiality for this town, than seemed consistent with the interests of the German princes, or the shortness of his visit to the Empire. Not content with strongly fortifying it, he erected at the opposite angle which the Maine forms with the Rhine, a new citadel, which was named Gustavusburg from its founder, but which is better known under the title of Pfaffenraub or Pfaffenzwang. — [Priests' plunder; alluding to the means by which the expense of its erection had been defrayed.]

While Gustavus Adolphus made himself master of the Rhine, and threatened the three neighbouring electorates with his victorious arms, his vigilant enemies in Paris and St. Germain's made use of every artifice to deprive him of the support of France, and, if possible, to involve him in a war with that power. By his sudden and equivocal march to the Rhine, he had surprised his friends, and furnished his enemies with the means of exciting a distrust of his intentions. After the conquest of Wurtzburg, and of the greater part of Franconia, the road into Bavaria and Austria lay open to him through Bamberg and the Upper Palatinate; and the expectation was as general, as it was natural, that he would not delay to attack the Emperor and the Duke of Bavaria in the very centre of their power, and, by the reduction of his two principal enemies, bring the war immediately to an end. But to the surprise of both parties, Gustavus left the path which general expectation had thus marked out for him; and instead of advancing to the right, turned to the left, to make the less important and more innocent princes of the Rhine feel his power, while he gave time to his more formidable opponents to recruit their strength. Nothing but the paramount design of reinstating the unfortunate Palatine, Frederick V., in the possession of his territories, by the expulsion of the Spaniards, could seem to account for this strange step; and the belief that Gustavus was about to effect that restoration, silenced for a while the suspicions of his friends and the calumnies of his enemies. But the Lower Palatinate was now almost entirely cleared of the enemy; and yet Gustavus continued to form new schemes of conquest on the Rhine, and to withhold the reconquered country from the Palatine, its rightful owner. In vain did the English ambassador remind him of what justice demanded, and what his own solemn engagement made a duty of honour; Gustavus replied to these demands with bitter complaints of the inactivity of the English court, and prepared to carry his victorious standard into Alsace, and even into Lorraine.

A distrust of the Swedish monarch was now loud and open, while the malice of his enemies busily circulated the most injurious reports as to his intentions. Richelieu, the minister of Louis XIII., had long witnessed with anxiety the king's progress towards the French frontier, and the suspicious temper of Louis rendered him but too accessible to the evil surmises which the occasion gave rise to. France was at this time involved in a civil war with her Protestant subjects, and the fear was not altogether groundless, that the approach of a victorious monarch of their party might revive their drooping spirit, and encourage them to a more desperate resistance. This might be the case, even if Gustavus Adolphus was far from showing a disposition to encourage them, or to act unfaithfully towards his ally, the King of France. But the vindictive Bishop of Wurtzburg, who was anxious to avenge the loss of his dominions, the envenomed rhetoric of the Jesuits and the active zeal of the Bavarian minister, represented this dreaded alliance between the Huguenots and the Swedes as an undoubted fact, and filled the timid mind of Louis with the most alarming fears. Not merely chimerical politicians, but many of the best informed Roman Catholics, fully believed that the king was on the point of breaking into the heart of France, to make common cause with the Huguenots, and to overturn the Catholic religion within the kingdom. Fanatical zealots already saw him, with his army, crossing the Alps, and dethroning the Viceregent of Christ in Italy. Such reports no doubt soon refute themselves; yet it cannot be denied that Gustavus, by his manoeuvres on the Rhine, gave a dangerous handle to the malice of his enemies, and in some measure justified the suspicion that he directed his arms, not so much against the Emperor and the Duke of Bavaria, as against the Roman Catholic religion itself.
