demanded the evacuation of Thuringia, Halberstadt, and Magdeburg. Philipsburg, the military depot of France, was surprised by the Austrians, with all the stores it contained; and this severe loss checked the activity of France. To complete the embarrassments of Sweden, the truce with Poland was drawing to a close. To support a war at the same time with Poland and in Germany, was far beyond the power of Sweden; and all that remained was to choose between them. Pride and ambition declared in favour of continuing the German war, at whatever sacrifice on the side of Poland. An army, however, was necessary to command the respect of Poland, and to give weight to Sweden in any negotiations for a truce or a peace.
The mind of Oxenstiern, firm, and inexhaustible in expedients, set itself manfully to meet these calamities, which all combined to overwhelm Sweden; and his shrewd understanding taught him how to turn even misfortunes to his advantage. The defection of so many German cities of the empire deprived him, it is true, of a great part of his former allies, but at the same time it freed him from the necessity of paying any regard to their interests. The more the number of his enemies increased, the more provinces and magazines were opened to his troops. The gross ingratitude of the States, and the haughty contempt with which the Emperor behaved, (who did not even condescend to treat directly with him about a peace,) excited in him the courage of despair, and a noble determination to maintain the struggle to the last. The continuance of war, however unfortunate it might prove, could not render the situation of Sweden worse than it now was; and if Germany was to be evacuated, it was at least better and nobler to do so sword in hand, and to yield to force rather than to fear.
In the extremity in which the Swedes were now placed by the desertion of their allies, they addressed themselves to France, who met them with the greatest encouragement. The interests of the two crowns were closely united, and France would have injured herself by allowing the Swedish power in Germany to decline. The helpless situation of the Swedes, was rather an additional motive with France to cement more closely their alliance, and to take a more active part in the German war. Since the alliance with Sweden, at Beerwald, in 1632, France had maintained the war against the Emperor, by the arms of Gustavus Adolphus, without any open or formal breach, by furnishing subsidies and increasing the number of his enemies. But alarmed at the unexpected rapidity and success of the Swedish arms, France, in anxiety to restore the balance of power, which was disturbed by the preponderance of the Swedes, seemed, for a time, to have lost sight of her original designs. She endeavoured to protect the Roman Catholic princes of the empire against the Swedish conqueror, by the treaties of neutrality, and when this plan failed, she even meditated herself to declare war against him. But no sooner had the death of Gustavus Adolphus, and the desperate situation of the Swedish affairs, dispelled this apprehension, than she returned with fresh zeal to her first design, and readily afforded in this misfortune the aid which in the hour of success she had refused. Freed from the checks which the ambition and vigilance of Gustavus Adolphus placed upon her plans of aggrandizement, France availed herself of the favourable opportunity afforded by the defeat of Nordlingen, to obtain the entire direction of the war, and to prescribe laws to those who sued for her powerful protection. The moment seemed to smile upon her boldest plans, and those which had formerly seemed chimerical, now appeared to be justified by circumstances. She now turned her whole attention to the war in Germany; and, as soon as she had secured her own private ends by a treaty with the Germans, she suddenly entered the political arena as an active and a commanding power. While the other belligerent states had been exhausting themselves in a tedious contest, France had been reserving her strength, and maintained the contest by money alone; but now, when the state of things called for more active measures, she seized the sword, and astonished Europe by the boldness and magnitude of her undertakings. At the same moment, she fitted out two fleets, and sent six different armies into the field, while she subsidized a foreign crown and several of the German princes. Animated by this powerful co-operation, the Swedes and Germans awoke from the consternation, and hoped, sword in hand, to obtain a more honourable peace than that of Prague. Abandoned by their confederates, who had been reconciled to the Emperor, they formed a still closer alliance with France, which increased her support with their growing necessities, at the same time taking a more active, although secret share in the German war, until at last, she threw off the mask altogether, and in her own name made an unequivocal declaration of war against the Emperor.
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 circumstances 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 Cassel, 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 bloody; 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 accumulation 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 assistance 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 bloody 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
