To leave Sweden at full liberty to act against Austria, France commenced her operations by liberating it from all fear of a Polish war.
By means of the Count d"Avaux, its minister, an agreement was concluded between the two powers at Stummsdorf in Prussia, by which the truce was prolonged for twenty-six years, though not without a great sacrifice on the part of the Swedes, who ceded by a single stroke of the pen almost the whole of Polish Prussia, the dear-bought conquest of Gustavus Adolphus. The treaty of Beerwald was, with certain modifications, which circ.u.mstances rendered necessary, renewed at different times at Compiegne, and afterwards at Wismar and Hamburg. France had already come to a rupture with Spain, in May, 1635, and the vigorous attack which it made upon that power, deprived the Emperor of his most valuable auxiliaries from the Netherlands. By supporting the Landgrave William of Ca.s.sel, and Duke Bernard of Weimar, the Swedes were enabled to act with more vigour upon the Elbe and the Danube, and a diversion upon the Rhine compelled the Emperor to divide his force.
The war was now prosecuted with increasing activity. By the treaty of Prague, the Emperor had lessened the number of his adversaries within the Empire; though, at the same time, the zeal and activity of his foreign enemies had been augmented by it. In Germany, his influence was almost unlimited, for, with the exception of a few states, he had rendered himself absolute master of the German body and its resources, and was again enabled to act in the character of emperor and sovereign.
The first fruit of his power was the elevation of his son, Ferdinand III., to the dignity of King of the Romans, to which he was elected by a decided majority of votes, notwithstanding the opposition of Treves, and of the heirs of the Elector Palatine. But, on the other hand, he had exasperated the Swedes to desperation, had armed the power of France against him, and drawn its troops into the heart of the kingdom.
France and Sweden, with their German allies, formed, from this moment, one firm and compactly united power; the Emperor, with the German states which adhered to him, were equally firm and united. The Swedes, who no longer fought for Germany, but for their own lives, showed no more indulgence; relieved from the necessity of consulting their German allies, or accounting to them for the plans which they adopted, they acted with more precipitation, rapidity, and boldness.
Battles, though less decisive, became more obstinate and b.l.o.o.d.y; greater achievements, both in bravery and military skill, were performed; but they were but insulated efforts; and being neither dictated by any consistent plan, nor improved by any commanding spirit, had comparatively little influence upon the course of the war.
Saxony had bound herself, by the treaty of Prague, to expel the Swedes from Germany. From this moment, the banners of the Saxons and Imperialists were united: the former confederates were converted into implacable enemies.
The archbishopric of Magdeburg which, by the treaty, was ceded to the prince of Saxony, was still held by the Swedes, and every attempt to acquire it by negociation had proved ineffectual. Hostilities commenced, by the Elector of Saxony recalling all his subjects from the army of Banner, which was encamped upon the Elbe. The officers, long irritated by the acc.u.mulation of their arrears, obeyed the summons, and evacuated one quarter after another. As the Saxons, at the same time, made a movement towards Mecklenburg, to take Doemitz, and to drive the Swedes from Pomerania and the Baltic, Banner suddenly marched thither, relieved Doemitz, and totally defeated the Saxon General Baudissin, with 7000 men, of whom 1000 were slain, and about the same number taken prisoners.
Reinforced by the troops and artillery, which had hitherto been employed in Polish Prussia, but which the treaty of Stummsdorf rendered unnecessary, this brave and impetuous general made, the following year (1636), a sudden inroad into the Electorate of Saxony, where he gratified his inveterate hatred of the Saxons by the most destructive ravages. Irritated by the memory of old grievances which, during their common campaigns, he and the Swedes had suffered from the haughtiness of the Saxons, and now exasperated to the utmost by the late defection of the Elector, they wreaked upon the unfortunate inhabitants all their rancour.
Against Austria and Bavaria, the Swedish soldier had fought from a sense, as it were, of duty; but against the Saxons, they contended with all the energy of private animosity and personal revenge, detesting them as deserters and traitors; for the hatred of former friends is of all the most fierce and irreconcileable. The powerful diversion made by the Duke of Weimar, and the Landgrave of Hesse, upon the Rhine and in Westphalia, prevented the Emperor from affording the necessary a.s.sistance to Saxony, and left the whole Electorate exposed to the destructive ravages of Banner"s army.
At length, the Elector, having formed a junction with the Imperial General Hatzfeld, advanced against Magdeburg, which Banner in vain hastened to relieve. The united army of the Imperialists and the Saxons now spread itself over Brandenburg, wrested several places from the Swedes, and almost drove them to the Baltic.
But, contrary to all expectation, Banner, who had been given up as lost, attacked the allies, on the 24th of September, 1636, at Wittstock, where a b.l.o.o.d.y battle took place. The onset was terrific; and the whole force of the enemy was directed against the right wing of the Swedes, which was led by Banner in person. The contest was long maintained with equal animosity and obstinacy on both sides.
There was not a squadron among the Swedes, which did not return ten times to the charge, to be as often repulsed; when at last, Banner was obliged to retire before the superior numbers of the enemy. His left wing sustained the combat until night, and the second line of the Swedes, which had not as yet been engaged, was prepared to renew it the next morning.
But the Elector did not wait for a second attack. His army was exhausted by the efforts of the preceding day; and, as the drivers had fled with the horses, his artillery was unserviceable. He accordingly retreated in the night, with Count Hatzfeld, and relinquished the ground to the Swedes.
About 5000 of the allies fell upon the field, exclusive of those who were killed in the pursuit, or who fell into the hands of the exasperated peasantry. One hundred and fifty standards and colours, twenty-three pieces of cannon, the whole baggage and silver plate of the Elector, were captured, and more than 2000 men taken prisoners.
This brilliant victory, achieved over an enemy far superior in numbers, and in a very advantageous position, restored the Swedes at once to their former reputation; their enemies were discouraged, and their friends inspired with new hopes. Banner instantly followed up this decisive success, and hastily crossing the Elbe, drove the Imperialists before him, through Thuringia and Hesse, into Westphalia. He then returned, and took up his winter quarters in Saxony.
But, without the material aid furnished by the diversion upon the Rhine, and the activity there of Duke Bernard and the French, these important successes would have been unattainable. Duke Bernard, after the defeat of Nordlingen, reorganized his broken army at Wetterau; but, abandoned by the confederates of the League of Heilbronn, which had been dissolved by the peace of Prague, and receiving little support from the Swedes, he found himself unable to maintain an army, or to perform any enterprise of importance. The defeat at Nordlingen had terminated all his hopes on the Duchy of Franconia, while the weakness of the Swedes, destroyed the chance of retrieving his fortunes through their a.s.sistance.
Tired, too, of the constraint imposed upon him by the imperious chancellor, he turned his attention to France, who could easily supply him with money, the only aid which he required, and France readily acceded to his proposals.
Richelieu desired nothing so much as to diminish the influence of the Swedes in the German war, and to obtain the direction of it for himself. To secure this end, nothing appeared more effectual than to detach from the Swedes their bravest general, to win him to the interests of France, and to secure for the execution of its projects the services of his arm.
From a prince like Bernard, who could not maintain himself without foreign support, France had nothing to fear, since no success, however brilliant, could render him independent of that crown.
Bernard himself came into France, and in October, 1635, concluded a treaty at St. Germaine en Laye, not as a Swedish general, but in his own name, by which it was stipulated that he should receive for himself a yearly pension of one million five hundred thousand livres, and four millions for the support of his army, which he was to command under the orders of the French king. To inflame his zeal, and to accelerate the conquest of Alsace, France did not hesitate, by a secret article, to promise him that province for his services; a promise which Richelieu had little intention of performing, and which the duke also estimated at its real worth. But Bernard confided in his good fortune, and in his arms, and met artifice with dissimulation. If he could once succeed in wresting Alsace from the enemy, he did not despair of being able, in case of need, to maintain it also against a friend. He now raised an army at the expense of France, which he commanded nominally under the orders of that power, but in reality without any limitation whatever, and without having wholly abandoned his engagements with Sweden.
He began his operations upon the Rhine, where another French army, under Cardinal Lavalette, had already, in 1635, commenced hostilities against the Emperor.
Against this force, the main body of the Imperialists, after the great victory of Nordlingen, and the reduction of Swabia and Franconia had advanced under the command of Gallas, had driven them as far as Metz, cleared the Rhine, and took from the Swedes the towns of Metz and Frankenthal, of which they were in possession. But frustrated by the vigorous resistance of the French, in his main object, of taking up his winter quarters in France, he led back his exhausted troops into Alsace and Swabia.
At the opening of the next campaign, he pa.s.sed the Rhine at Breysach, and prepared to carry the war into the interior of France.
He actually entered Burgundy, while the Spaniards from the Netherlands made progress in Picardy; and John De Werth, a formidable general of the League, and a celebrated partisan, pushed his march into Champagne, and spread consternation even to the gates of Paris.
But an insignificant fortress in Franche Comte completely checked the Imperialists, and they were obliged, a second time, to abandon their enterprise.
The activity of Duke Bernard had hitherto been impeded by his dependence on a French general, more suited to the priestly robe, than to the baton of command; and although, in conjunction with him, he conquered Alsace Saverne, he found himself unable, in the years 1636 and 1637, to maintain his position upon the Rhine. The ill success of the French arms in the Netherlands had cheated the activity of operations in Alsace and Breisgau; but in 1638, the war in that quarter took a more brilliant turn. Relieved from his former restraint, and with unlimited command of his troops, Duke Bernard, in the beginning of February, left his winter quarters in the bishopric of Basle, and unexpectedly appeared upon the Rhine, where, at this rude season of the year, an attack was little antic.i.p.ated.
The forest towns of Laufenburg, Waldshut, and Seckingen, were surprised, and Rhinefeldt besieged. The Duke of Savelli, the Imperial general who commanded in that quarter, hastened by forced marches to the relief of this important place, succeeded in raising the siege, and compelled the Duke of Weimar, with great loss to retire.
But, contrary to all human expectation, he appeared on the third day after, (21st February, 1638,) before the Imperialists, in order of battle, and defeated them in a b.l.o.o.d.y engagement, in which the four Imperial generals, Savelli, John De Werth, Enkeford, and Sperreuter, with 2000 men, were taken prisoners. Two of these, De Werth and Enkeford, were afterwards sent by Richelieu"s orders into France, in order to flatter the vanity of the French by the sight of such distinguished prisoners, and by the pomp of military trophies, to withdraw the attention of the populace from the public distress.
The captured standards and colours were, with the same view, carried in solemn procession to the church of Notre Dame, thrice exhibited before the altar, and committed to sacred custody.
The taking of Rhinefeldt, Roeteln, and Fribourg, was the immediate consequence of the duke"s victory. His army now increased by considerable recruits, and his projects expanded in proportion as fortune favoured him.
The fortress of Breysach upon the Rhine was looked upon as holding the command of that river, and as the key of Alsace. No place in this quarter was of more importance to the Emperor, and upon none had more care been bestowed.
To protect Breysach, was the princ.i.p.al destination of the Italian army, under the Duke of Feria; the strength of its works, and its natural defences, bade defiance to a.s.sault, while the Imperial generals who commanded in that quarter had orders to retain it at any cost. But the duke, trusting to his good fortune, resolved to attempt the siege.
Its strength rendered it impregnable; it could, therefore, only be starved into a surrender; and this was facilitated by the carelessness of the commandant, who, expecting no attack, had been selling off his stores.
As under these circ.u.mstances the town could not long hold out, it must be immediately relieved or victualled. Accordingly, the Imperial General Goetz rapidly advanced at the head of 12,000 men, accompanied by 3000 waggons loaded with provisions, which he intended to throw into the place. But he was attacked with such vigour by Duke Bernard at Witteweyer, that he lost his whole force, except 3000 men, together with the entire transport. A similar fate at Ochsenfeld, near Thann, overtook the Duke of Lorraine, who, with 5000 or 6000 men, advanced to relieve the fortress. After a third attempt of general Goetz for the relief of Breysach had proved ineffectual, the fortress, reduced to the greatest extremity by famine, surrendered, after a blockade of four months, on the 17th December 1638, to its equally persevering and humane conqueror.
The capture of Breysach opened a boundless field to the ambition of the Duke of Weimar, and the romance of his hopes was fast approaching to reality. Far from intending to surrender his conquests to France, he destined Breysach for himself, and revealed this intention, by exacting allegiance from the vanquished, in his own name, and not in that of any other power. Intoxicated by his past success, and excited by the boldest hopes, he believed that he should be able to maintain his conquests, even against France herself.
At a time when everything depended upon bravery, when even personal strength was of importance, when troops and generals were of more value than territories, it was natural for a hero like Bernard to place confidence in his own powers, and, at the head of an excellent army, who under his command had proved invincible, to believe himself capable of accomplishing the boldest and largest designs. In order to secure himself one friend among the crowd of enemies whom he was about to provoke, he turned his eyes upon the Landgravine Amelia of Hesse, the widow of the lately deceased Landgrave William, a princess whose talents were equal to her courage, and who, along with her hand, would bestow valuable conquests, an extensive princ.i.p.ality, and a well disciplined army.
By the union of the conquests of Hesse, with his own upon the Rhine, and the junction of their forces, a power of some importance, and perhaps a third party, might be formed in Germany, which might decide the fate of the war. But a premature death put a period to these extensive schemes.
"Courage, Father Joseph, Breysach is ours!" whispered Richelieu in the ear of the Capuchin, who had long held himself in readiness to be despatched into that quarter; so delighted was he with this joyful intelligence. Already in imagination he held Alsace, Breisgau, and all the frontiers of Austria in that quarter, without regard to his promise to Duke Bernard. But the firm determination which the latter had unequivocally shown, to keep Breysach for himself, greatly embarra.s.sed the cardinal, and no efforts were spared to retain the victorious Bernard in the interests of France.
He was invited to court, to witness the honours by which his triumph was to be commemorated; but he perceived and shunned the seductive snare.
The cardinal even went so far as to offer him the hand of his niece in marriage; but the proud German prince declined the offer, and refused to sully the blood of Saxony by a misalliance.
He was now considered as a dangerous enemy, and treated as such.
His subsidies were withdrawn; and the Governor of Breysach and his princ.i.p.al officers were bribed, at least upon the event of the duke"s death, to take possession of his conquests, and to secure his troops. These intrigues were no secret to the duke, and the precautions he took in the conquered places, clearly bespoke the distrust of France. But this misunderstanding with the French court had the most prejudicial influence upon his future operations.
The preparations he was obliged to make, in order to secure his conquests against an attack on the side of France, compelled him to divide his military strength, while the stoppage of his subsidies delayed his appearance in the field. It had been his intention to cross the Rhine, to support the Swedes, and to act against the Emperor and Bavaria on the banks of the Danube. He had already communicated his plan of operations to Banner, who was about to carry the war into the Austrian territories, and had promised to relieve him so, when a sudden death cut short his heroic career, in the 36th year of his age, at Neuburgh upon the Rhine (in July, 1639).
He died of a pestilential disorder, which, in the course of two days, had carried off nearly 400 men in his camp. The black spots which appeared upon his body, his own dying expressions, and the advantages which France was likely to reap from his sudden decease, gave rise to a suspicion that he had been removed by poison -- a suspicion sufficiently refuted by the symptoms of his disorder. In him, the allies lost their greatest general after Gustavus Adolphus, France a formidable compet.i.tor for Alsace, and the Emperor his most dangerous enemy. Trained to the duties of a soldier and a general in the school of Gustavus Adolphus, he successfully imitated his eminent model, and wanted only a longer life to equal, if not to surpa.s.s it. With the bravery of the soldier, he united the calm and cool penetration of the general and the persevering fort.i.tude of the man, with the daring resolution of youth; with the wild ardour of the warrior, the sober dignity of the prince, the moderation of the sage, and the conscientiousness of the man of honour.
Discouraged by no misfortune, he quickly rose again in full vigour from the severest defeats; no obstacles could check his enterprise, no disappointments conquer his indomitable perseverance. His genius, perhaps, soared after unattainable objects; but the prudence of such men, is to be measured by a different standard from that of ordinary people.
Capable of accomplishing more, he might venture to form more daring plans.
Bernard affords, in modern history, a splendid example of those days of chivalry, when personal greatness had its full weight and influence, when individual bravery could conquer provinces, and the heroic exploits of a German knight raised him even to the Imperial throne.
The best part of the duke"s possessions were his army, which, together with Alsace, he bequeathed to his brother William. But to this army, both France and Sweden thought that they had well-grounded claims; the latter, because it had been raised in name of that crown, and had done homage to it; the former, because it had been supported by its subsidies.
The Electoral Prince of the Palatinate also negociated for its services, and attempted, first by his agents, and latterly in his own person, to win it over to his interests, with the view of employing it in the reconquest of his territories. Even the Emperor endeavoured to secure it, a circ.u.mstance the less surprising, when we reflect that at this time the justice of the cause was comparatively unimportant, and the extent of the recompense the main object to which the soldier looked; and when bravery, like every other commodity, was disposed of to the highest bidder. But France, richer and more determined, outbade all compet.i.tors: it bought over General Erlach, the commander of Breysach, and the other officers, who soon placed that fortress, with the whole army, in their hands.
The young Palatine, Prince Charles Louis, who had already made an unsuccessful campaign against the Emperor, saw his hopes again deceived.
Although intending to do France so ill a service, as to compete with her for Bernard"s army, he had the imprudence to travel through that kingdom.
The cardinal, who dreaded the justice of the Palatine"s cause, was glad to seize any opportunity to frustrate his views. He accordingly caused him to be seized at Moulin, in violation of the law of nations, and did not set him at liberty, until he learned that the army of the Duke of Weimar had been secured. France was now in possession of a numerous and well disciplined army in Germany, and from this moment began to make open war upon the Emperor.
But it was no longer against Ferdinand II. that its hostilities were to be conducted; for that prince had died in February, 1637, in the 59th year of his age. The war which his ambition had kindled, however, survived him. During a reign of eighteen years he had never once laid aside the sword, nor tasted the blessings of peace as long as his hand swayed the imperial sceptre. Endowed with the qualities of a good sovereign, adorned with many of those virtues which ensure the happiness of a people, and by nature gentle and humane, we see him, from erroneous ideas of the monarch"s duty, become at once the instrument and the victim of the evil pa.s.sions of others; his benevolent intentions frustrated, and the friend of justice converted into the oppressor of mankind, the enemy of peace, and the scourge of his people. Amiable in domestic life, and respectable as a sovereign, but in his policy ill advised, while he gained the love of his Roman Catholic subjects, he incurred the execration of the Protestants. History exhibits many and greater despots than Ferdinand II., yet he alone has had the unfortunate celebrity of kindling a thirty years" war; but to produce its lamentable consequences, his ambition must have been seconded by a kindred spirit of the age, a congenial state of previous circ.u.mstances, and existing seeds of discord.
At a less turbulent period, the spark would have found no fuel; and the peacefulness of the age would have choked the voice of individual ambition; but now the flash fell upon a pile of acc.u.mulated combustibles, and Europe was in flames.
His son, Ferdinand III., who, a few months before his father"s death, had been raised to the dignity of King of the Romans, inherited his throne, his principles, and the war which he had caused. But Ferdinand III.
had been a closer witness of the sufferings of the people, and the devastation of the country, and felt more keenly and ardently the necessity of peace. Less influenced by the Jesuits and the Spaniards, and more moderate towards the religious views of others, he was more likely than his father to listen to the voice of reason.
He did so, and ultimately restored to Europe the blessing of peace, but not till after a contest of eleven years waged with sword and pen; not till after he had experienced the impossibility of resistance, and necessity had laid upon him its stern laws.
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 circ.u.mstances, 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 t.i.tle to Pomerania. To prevent the Elector of Brandenburg from making good the t.i.tle 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 princ.i.p.al 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, a.s.sumed 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 circ.u.mstance, 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, a.s.sumed 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 Ca.s.sel 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.
