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 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 assistance.
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.
