Fortune favoured him at the commencement of his reign, and his arms were victorious against the Swedes. The latter, under the command of the victorious Banner, had, after their success at Wittstock, taken up their winter quarters in Saxony; and the campaign of 1637 opened with the siege of Leipzig. The vigorous resistance of the garrison, and the approach of the Electoral and Imperial armies, saved the town, and Banner, to prevent his communication with the Elbe being cut off, was compelled to retreat into Torgau. But the superior number of the Imperialists drove him even from that quarter; and, surrounded by the enemy, hemmed in by rivers, and suffering from famine, he had no course open to him but to attempt a highly dangerous retreat into Pomerania, of which, the boldness and successful issue border upon romance. The whole army crossed the Oder, at a ford near Furstenberg; and the soldiers, wading up to the neck in water, dragged the artillery across, when the horses refused to draw. Banner had expected to be joined by General Wrangel, on the farther side of the Oder in Pomerania; and, in conjunction with him, to be able to make head against the enemy. But Wrangel did not appear; and in his stead, he found an Imperial army posted at Landsberg, with a view to cut off the retreat of the Swedes. Banner now saw that he had fallen into a dangerous snare, from which escape appeared impossible. In his rear lay an exhausted country, the Imperialists, and the Oder on his left; the Oder, too, guarded by the Imperial General Bucheim, offered no retreat; in front, Landsberg, Custrin, the Warta, and a hostile army; and on the right, Poland, in which, notwithstanding the truce, little confidence could be placed. In these circumstances, his position seemed hopeless, and the Imperialists were already triumphing in the certainty of his fall. Banner, with just indignation, accused the French as the authors of this misfortune. They had neglected to make, according to their promise, a diversion upon the Rhine; and, by their inaction, allowed the Emperor to combine his whole force upon the Swedes. "When the day comes," cried the incensed General to the French Commissioner, who followed the camp, "that the Swedes and Germans join their arms against France, we shall cross the Rhine with less ceremony." But reproaches were now useless; what the emergency demanded was energy and resolution. In the hope of drawing the enemy by stratagem from the Oder, Banner pretended to march towards Poland, and despatched the greater part of his baggage in this direction, with his own wife, and those of the other officers. The Imperialists immediately broke up their camp, and hurried towards the Polish frontier to block up the route; Bucheim left his station, and the Oder was stripped of its defenders. On a sudden, and under cloud of night, Banner turned towards that river, and crossed it about a mile above Custrin, with his troops, baggage, and artillery, without bridges or vessels, as he had done before at Furstenberg. He reached Pomerania without loss, and prepared to share with Wrangel the defence of that province.
But the Imperialists, under the command of Gallas, entered that duchy at Ribses, and overran it by their superior strength. Usedom and Wolgast were taken by storm, Demmin capitulated, and the Swedes were driven far into Lower Pomerania. It was, too, more important for them at this moment than ever, to maintain a footing in that country, for Bogislaus XIV. had died that year, and Sweden must prepare to establish its title to Pomerania. To prevent the Elector of Brandenburg from making good the title to that duchy, which the treaty of Prague had given him, Sweden exerted her utmost energies, and supported its generals to the extent of her ability, both with troops and money. In other quarters of the kingdom, the affairs of the Swedes began to wear a more favourable aspect, and to recover from the humiliation into which they had been thrown by the inaction of France, and the desertion of their allies. For, after their hasty retreat into Pomerania, they had lost one place after another in Upper Saxony; the princes of Mecklenburg, closely pressed by the troops of the Emperor, began to lean to the side of Austria, and even George, Duke of Lunenburg, declared against them. Ehrenbreitstein was starved into a surrender by the Bavarian General de Werth, and the Austrians possessed themselves of all the works which had been thrown up on the Rhine. France had been the sufferer in the contest with Spain; and the event had by no means justified the pompous expectations which had accompanied the opening of the campaign. Every place which the Swedes had held in the interior of Germany was lost; and only the principal towns in Pomerania still remained in their hands. But a single campaign raised them from this state of humiliation; and the vigorous diversion, which the victorious Bernard had effected upon the Rhine, gave quite a new turn to affairs.
The misunderstandings between France and Sweden were now at last adjusted, and the old treaty between these powers confirmed at Hamburg, with fresh advantages for Sweden. In Hesse, the politic Landgravine Amelia had, with the approbation of the Estates, assumed the government after the death of her husband, and resolutely maintained her rights against the Emperor and the House of Darmstadt. Already zealously attached to the Swedish Protestant party, on religious grounds, she only awaited a favourable opportunity openly to declare herself. By artful delays, and by prolonging the negociations with the Emperor, she had succeeded in keeping him inactive, till she had concluded a secret compact with France, and the victories of Duke Bernard had given a favourable turn to the affairs of the Protestants. She now at once threw off the mask, and renewed her former alliance with the Swedish crown. The Electoral Prince of the Palatinate was also stimulated, by the success of Bernard, to try his fortune against the common enemy. Raising troops in Holland with English money, he formed a magazine at Meppen, and joined the Swedes in Westphalia. His magazine was, however, quickly lost; his army defeated near Flotha, by Count Hatzfeld; but his attempt served to occupy for some time the attention of the enemy, and thereby facilitated the operations of the Swedes in other quarters. Other friends began to appear, as fortune declared in their favour, and the circumstance, that the States of Lower Saxony embraced a neutrality, was of itself no inconsiderable advantage.
Under these advantages, and reinforced by 14,000 fresh troops from Sweden and Livonia. Banner opened, with the most favourable prospects, the campaign of 1638. The Imperialists who were in possession of Upper Pomerania and Mecklenburg, either abandoned their positions, or deserted in crowds to the Swedes, to avoid the horrors of famine, the most formidable enemy in this exhausted country. The whole country betwixt the Elbe and the Oder was so desolated by the past marchings and quarterings of the troops, that, in order to support his army on its march into Saxony and Bohemia, Banner was obliged to take a circuitous route from Lower Pomerania into Lower Saxony, and then into the Electorate of Saxony through the territory of Halberstadt. The impatience of the Lower Saxon States to get rid of such troublesome guests, procured him so plentiful a supply of provisions, that he was provided with bread in Magdeburg itself, where famine had even overcome the natural antipathy of men to human flesh. His approach spread consternation among the Saxons; but his views were directed not against this exhausted country, but against the hereditary dominions of the Emperor. The victories of Bernard encouraged him, while the prosperity of the Austrian provinces excited his hopes of booty. After defeating the Imperial General Salis, at Elsterberg, totally routing the Saxon army at Chemnitz, and taking Pirna, he penetrated with irresistible impetuosity into Bohemia, crossed the Elbe, threatened Prague, took Brandeis and Leutmeritz, defeated General Hofkirchen with ten regiments, and spread terror and devastation through that defenceless kingdom. Booty was his sole object, and whatever he could not carry off he destroyed. In order to remove more of the corn, the ears were cut from the stalks, and the latter burnt. Above a thousand castles, hamlets, and villages were laid in ashes; sometimes more than a hundred were seen burning in one night. From Bohemia he crossed into Silesia, and it was his intention to carry his ravages even into Moravia and Austria. But to prevent this, Count Hatzfeld was summoned from Westphalia, and Piccolomini from the Netherlands, to hasten with all speed to this quarter. The Archduke Leopold, brother to the Emperor, assumed the command, in order to repair the errors of his predecessor Gallas, and to
raise the army from the low ebb to which it had fallen.
The result justified the change, and the campaign of 1640 appeared to take a most unfortunate turn for the Swedes. They were successively driven out of all their posts in Bohemia, and anxious only to secure their plunder, they precipitately crossed the heights of Meissen. But being followed into Saxony by the pursuing enemy, and defeated at Plauen, they were obliged to take refuge in Thuringia. Made masters of the field in a single summer, they were as rapidly dispossessed; but only to acquire it a second time, and to hurry from one extreme to another. The army of Banner, weakened and on the brink of destruction in its camp at Erfurt, suddenly recovered itself. The Duke of Lunenburg abandoned the treaty of Prague, and joined Banner with the very troops which, the year before, had fought against him. Hesse Cassel sent reinforcements, and the Duke of Longueville came to his support with the army of the late Duke Bernard. Once more numerically superior to the Imperialists, Banner offered them battle near Saalfeld; but their leader, Piccolomini, prudently declined an engagement, having chosen too strong a position to be forced. When the Bavarians at length separated from the Imperialists, and marched towards Franconia, Banner attempted an attack upon this divided corps, but the attempt was frustrated by the skill of the Bavarian General Von Mercy, and the near approach of the main body of the Imperialists. Both armies now moved into the exhausted territory of Hesse, where they formed intrenched camps near each other, till at last famine and the severity of the winter compelled them both to retire. Piccolomini chose the fertile banks of the Weser for his winter quarters; but being outflanked by Banner, he was obliged to give way to the Swedes, and to impose on the Franconian sees the burden of maintaining his army.
At this period, a diet was held in Ratisbon, where the complaints of the States were to be heard, measures taken for securing the repose of the Empire, and the question of peace or war finally settled. The presence of the Emperor, the majority of the Roman Catholic voices in the Electoral College, the great number of bishops, and the withdrawal of several of the Protestant votes, gave the Emperor a complete command of the deliberations of the assembly, and rendered this diet any thing but a fair representative of the opinions of the German Empire. The Protestants, with reason, considered it as a mere combination of Austria and its creatures against their party; and it seemed to them a laudable effort to interrupt its deliberations, and to dissolve the diet itself.
Banner undertook this bold enterprise. His military reputation had suffered by his last retreat from Bohemia, and it stood in need of some great exploit to restore its former lustre. Without communicating his designs to any one, in the depth of the winter of 1641, as soon as the roads and rivers were frozen, he broke up from his quarters in Lunenburg. Accompanied by Marshal Guebriant, who commanded the armies of France and Weimar, he took the route towards the Danube, through Thuringia and Vogtland, and appeared before Ratisbon, ere the Diet could be apprised of his approach. The consternation of the assembly was indescribable; and, in the first alarm, the deputies prepared for flight. The Emperor alone declared that he would not leave the town, and encouraged the rest by his example. Unfortunately for the Swedes, a thaw came on, which broke up the ice upon the Danube, so that it was no longer passable on foot, while no boats could cross it, on account of the quantities of ice which were swept down by the current. In order to perform something, and to humble the pride of the Emperor, Banner discourteously fired 500 cannon shots into the town, which, however, did little mischief. Baffled in his designs, he resolved to penetrate farther into Bavaria, and the defenceless province of Moravia, where a rich booty and comfortable quarters awaited his troops. Guebriant, however, began to fear that the purpose of the Swedes was to draw the army of Bernard away from the Rhine, and to cut off its communication with France, till it should be either entirely won over, or incapacitated from acting independently. He therefore separated from Banner to return to the Maine; and the latter was exposed to the whole force of the Imperialists, which had been secretly drawn together between Ratisbon and Ingoldstadt, and was on its march against him. It was now time to think of a rapid retreat, which, having to be effected in the face of an army superior in cavalry, and betwixt woods and rivers, through a country entirely hostile, appeared almost impracticable. He hastily retired towards the Forest, intending to penetrate through Bohemia into Saxony; but he was obliged to sacrifice three regiments at Neuburg. These with a truly Spartan courage, defended themselves for four days behind an old wall, and gained time for Banner to escape. He retreated by Egra to Annaberg; Piccolomini took a shorter route in pursuit, by Schlakenwald; and Banner succeeded, only by a single half hour, in clearing the Pass of Prisnitz, and saving his whole army from the Imperialists. At Zwickau he was again joined by Guebriant; and both generals directed their march towards Halberstadt, after in vain attempting to defend the Saal, and to prevent the passage of the Imperialists.
Banner, at length, terminated his career at Halberstadt, in May 1641, a victim to vexation and disappointment. He sustained with great renown, though with varying success, the reputation of the Swedish arms in Germany, and by a train of victories showed himself worthy of his great master in the art of war. He was fertile in expedients, which he planned with secrecy, and executed with boldness; cautious in the midst of dangers, greater in adversity than in prosperity, and never more formidable than when upon the brink of destruction. But the virtues of the hero were united with all the railings and vices which a military life creates, or at least fosters. As imperious in private life as he was at the head of his army, rude as his profession, and proud as a conqueror; he oppressed the German princes no less by his haughtiness, than their country by his contributions. He consoled himself for the toils of war in voluptuousness and the pleasures of the table, in which he indulged to excess, and was thus brought to an early grave. But though as much addicted to pleasure as Alexander or Mahomet the Second, he hurried from the arms of luxury into the hardest fatigues, and placed himself in all his vigour at the head of his army, at the very moment his soldiers were murmuring at his luxurious excesses. Nearly 80,000 men fell in the numerous battles which he fought, and about 600 hostile standards and colours, which he sent to Stockholm, were the trophies of his victories. The want of this great general was soon severely felt by the Swedes, who feared, with justice, that the loss would not readily be replaced. The spirit of rebellion and insubordination, which had been overawed by the imperious demeanour of this dreaded commander, awoke upon his death. The officers, with an alarming unanimity, demanded payment of their arrears; and none of the four generals who shared the command, possessed influence enough to satisfy these demands, or to silence the malcontents. All discipline was at an end, increasing want, and the imperial citations were daily diminishing the number of the army; the troops of France and Weimar showed little zeal; those of Lunenburg forsook the Swedish colours; the Princes also of the House of Brunswick, after the death of Duke George, had formed a separate treaty with the Emperor; and at last even those of Hesse quitted them, to seek better quarters in Westphalia. The enemy profited by these calamitous divisions; and although defeated with loss in two pitched battles, succeeded in making considerable progress in Lower Saxony.
At length appeared the new Swedish generalissimo, with fresh troops and money. This was Bernard Torstensohn, a pupil of Gustavus Adolphus, and his most successful imitator, who had been his page during the Polish war. Though a martyr to the gout, and confined to a litter, he surpassed all his opponents in activity; and his enterprises had wings, while his body was held by the most frightful of fetters. Under him, the scene of war was changed, and new maxims adopted, which necessity dictated, and the issue justified. All the countries in which the contest had hitherto raged were exhausted; while the House of Austria, safe in its more distant territories, felt not the miseries of the war under which the rest of Germany groaned. Torstensohn first furnished them with this bitter experience, glutted his Swedes on the fertile produce of Austria, and carried the to
rch of war to the very footsteps of the imperial throne.
In Silesia, the enemy had gained considerable advantages over the Swedish general Stalhantsch, and driven him as far as Neumark. Torstensohn, who had joined the main body of the Swedes in Lunenburg, summoned him to unite with his force, and in the year 1642 hastily marched into Silesia through Brandenburg, which, under its great Elector, had begun to maintain an armed neutrality. Glogau was carried, sword in hand, without a breach, or formal approaches; the Duke Francis Albert of Lauenburg defeated and killed at Schweidnitz; and Schweidnitz itself with almost all the towns on that side of the Oder, taken. He now penetrated with irresistible violence into the interior of Moravia, where no enemy of Austria had hitherto appeared, took Olmutz, and threw Vienna itself into consternation.
But, in the mean time, Piccolomini and the Archduke Leopold had collected a superior force, which speedily drove the Swedish conquerors from Moravia, and after a fruitless attempt upon Brieg, from Silesia. Reinforced by Wrangel, the Swedes again attempted to make head against the enemy, and relieved Grossglogau; but could neither bring the Imperialists to an engagement, nor carry into effect their own views upon Bohemia. Overrunning Lusatia, they took Zittau, in presence of the enemy, and after a short stay in that country, directed their march towards the Elbe, which they passed at Torgau. Torstensohn now threatened Leipzig with a siege, and hoped to raise a large supply of provisions and contributions from that prosperous town, which for ten years had been unvisited with the scourge of war.
