Meantime, this defeat of the French was calculated to prove highly disastrous to Sweden, as the whole power of the Emperor might now act against them, while the number of their enemies was increased by a formidable accession.
Torstensohn had, in September, 1643, suddenly left Moravia, and moved into Silesia. The cause of this step was a secret, and the frequent changes which took place in the direction of his march, contributed to increase this perplexity. From Silesia, after numberless circuits, he advanced towards the Elbe, while the Imperialists followed him into Lusatia. Throwing a bridge across the Elbe at Torgau, he gave out that he intended to penetrate through Meissen into the Upper Palatinate in Bavaria;at Barby he also made a movement, as if to pass that river, but continued to move down the Elbe as far as Havelburg, where he astonished his troops by informing them that he was leading them against the Danes in Holstein.
The partiality which Christian IV. had displayed against the Swedes in his office of mediator, the jealousy which led him to do all in his power to hinder the progress of their arms, the restraints which he laid upon their navigation of the Sound, and the burdens which he imposed upon their commerce, had long roused the indignation of Sweden; and, at last, when these grievances increased daily, had determined the Regency to measures of retaliation. Dangerous as it seemed, to involve the nation in a new war, when, even amidst its conquests, it was almost exhausted by the old, the desire of revenge, and the deep-rooted hatred which subsisted between Danes and Swedes, prevailed over all other considerations;and even the embarrassment in which hostilities with Germany had plunged it, only served as an additional motive to try its fortune against Denmark.
Matters were, in fact, arrived at last to that extremity, that the war was prosecuted merely for the purpose of furnishing food and employment to the troops; that good winter quarters formed the chief subject of contention; and that success, in this point, was more valued than a decisive victory. But now the provinces of Germany were almost all exhausted and laid waste. They were wholly destitute of provisions, horses, and men, which in Holstein were to be found in profusion. If by this movement, Torstensohn should succeed merely in recruiting his army, providing subsistence for his horses and soldiers, and remounting his cavalry, all the danger and difficulty would be well repaid. Besides, it was highly important, on the eve of negotiations for peace, to diminish the injurious influence which Denmark might exercise upon these deliberations, to delay the treaty itself, which threatened to be prejudicial to the Swedish interests, by sowing confusion among the parties interested, and with a view to the amount of indemnification, to increase the number of her conquests, in order to be the more sure of securing those which alone she was anxious to retain. Moreover, the present state of Denmark justified even greater hopes, if only the attempt were executed with rapidity and silence. The secret was in fact so well kept in Stockholm, that the Danish minister had not the slightest suspicion of it;and neither France nor Holland were let into the scheme. Actual hostilities commenced with the declaration of war; and Torstensohn was in Holstein, before even an attack was expected. The Swedish troops, meeting with no resistance, quickly overran this duchy, and made themselves masters of all its strong places, except Rensburg and Gluckstadt.
Another army penetrated into Schonen, which made as little opposition;and nothing but the severity of the season prevented the enemy from passing the Lesser Baltic, and carrying the war into Funen and Zealand.
The Danish fleet was unsuccessful at Femern; and Christian himself, who was on board, lost his right eye by a splinter. Cut off from all communication with the distant force of the Emperor, his ally, this king was on the point of seeing his whole kingdom overrun by the Swedes;and all things threatened the speedy fulfilment of the old prophecy of the famous Tycho Brahe, that in the year 1644, Christian IV. should wander in the greatest misery from his dominions.
But the Emperor could not look on with indifference, while Denmark was sacrificed to Sweden, and the latter strengthened by so great an acquisition.
Notwithstanding great difficulties lay in the way of so long a march through desolated provinces, he did not hesitate to despatch an army into Holstein under Count Gallas, who, after Piccolomini's retirement, had resumed the supreme command of the troops. Gallas accordingly appeared in the duchy, took Keil, and hoped, by forming a junction with the Danes, to be able to shut up the Swedish army in Jutland. Meantime, the Hessians, and the Swedish General Koenigsmark, were kept in check by Hatzfeldt, and the Archbishop of Bremen, the son of Christian IV.; and afterwards the Swedes drawn into Saxony by an attack upon Meissen. But Torstensohn, with his augmented army, penetrated through the unoccupied pass betwixt Schleswig and Stapelholm, met Gallas, and drove him along the whole course of the Elbe, as far as Bernburg, where the Imperialists took up an entrenched position. Torstensohn passed the Saal, and by posting himself in the rear of the enemy, cut off their communication with Saxony and Bohemia. Scarcity and famine began now to destroy them in great numbers, and forced them to retreat to Magdeburg, where, however, they were not much better off. The cavalry, which endeavoured to escape into Silesia, was overtaken and routed by Torstensohn, near Juterbock;the rest of the army, after a vain attempt to fight its way through the Swedish lines, was almost wholly destroyed near Magdeburg.
