Nuremberg had exerted itself, almost beyond its power, to subsist for eleven weeks the vast crowd which was compressed within its boundaries;but its means were at length exhausted, and the king's more numerous party was obliged to determine on a retreat. By the casualties of war and sickness, Nuremberg had lost more than 10,000 of its inhabitants, and Gustavus Adolphus nearly 20,000 of his soldiers. The fields around the city were trampled down, the villages lay in ashes, the plundered peasantry lay faint and dying on the highways; foul odours infected the air, and bad food, the exhalations from so dense a population, and so many putrifying carcasses, together with the heat of the dog-days, produced a desolating pestilence which raged among men and beasts, and long after the retreat of both armies, continued to load the country with misery and distress. Affected by the general distress, and despairing of conquering the steady determination of the Duke of Friedland, the king broke up his camp on the 8th September, leaving in Nuremberg a sufficient garrison. He advanced in full order of battle before the enemy, who remained motionless, and did not attempt in the least to harass his retreat. His route lay by the Aisch and Windsheim towards Neustadt, where he halted five days to refresh his troops, and also to be near to Nuremberg, in case the enemy should make an attempt upon the town. But Wallenstein, as exhausted as himself, had only awaited the retreat of the Swedes to commence his own.
Five days afterwards, he broke up his camp at Zirndorf, and set it on fire.
A hundred columns of smoke, rising from all the burning villages in the neighbourhood, announced his retreat, and showed the city the fate it had escaped. His march, which was directed on Forchheim, was marked by the most frightful ravages; but he was too far advanced to be overtaken by the king. The latter now divided his army, which the exhausted country was unable to support, and leaving one division to protect Franconia, with the other he prosecuted in person his conquests in Bavaria.
In the mean time, the imperial Bavarian army had marched into the Bishopric of Bamberg, where the Duke of Friedland a second time mustered his troops. He found this force, which so lately had amounted to 60,000 men, diminished by the sword, desertion, and disease, to about 24,000, and of these a fourth were Bavarians.
Thus had the encampments before Nuremberg weakened both parties more than two great battles would have done, apparently without advancing the termination of the war, or satisfying, by any decisive result, the expectations of Europe. The king's conquests in Bavaria, were, it is true, checked for a time by this diversion before Nuremberg, and Austria itself secured against the danger of immediate invasion;but by the retreat of the king from that city, he was again left at full liberty to make Bavaria the seat of war. Indifferent towards the fate of that country, and weary of the restraint which his union with the Elector imposed upon him, the Duke of Friedland eagerly seized the opportunity of separating from this burdensome associate, and prosecuting, with renewed earnestness, his favourite plans. Still adhering to his purpose of detaching Saxony from its Swedish alliance, he selected that country for his winter quarters, hoping by his destructive presence to force the Elector the more readily into his views.
No conjuncture could be more favourable for his designs. The Saxons had invaded Silesia, where, reinforced by troops from Brandenburgh and Sweden, they had gained several advantages over the Emperor's troops.
Silesia would be saved by a diversion against the Elector in his own territories, and the attempt was the more easy, as Saxony, left undefended during the war in Silesia, lay open on every side to attack.
The pretext of rescuing from the enemy an hereditary dominion of Austria, would silence the remonstrances of the Elector of Bavaria, and, under the mask of a patriotic zeal for the Emperor's interests, Maximilian might be sacrificed without much difficulty. By giving up the rich country of Bavaria to the Swedes, he hoped to be left unmolested by them in his enterprise against Saxony, while the increasing coldness between Gustavus and the Saxon Court, gave him little reason to apprehend any extraordinary zeal for the deliverance of John George.
Thus a second time abandoned by his artful protector, the Elector separated from Wallenstein at Bamberg, to protect his defenceless territory with the small remains of his troops, while the imperial army, under Wallenstein, directed its march through Bayreuth and Coburg towards the Thuringian Forest.
An imperial general, Holk, had previously been sent into Vogtland with 6,000 men, to waste this defenceless province with fire and sword, he was soon followed by Gallas, another of the Duke's generals, and an equally faithful instrument of his inhuman orders. Finally, Pappenheim, too, was recalled from Lower Saxony, to reinforce the diminished army of the duke, and to complete the miseries of the devoted country. Ruined churches, villages in ashes, harvests wilfully destroyed, families plundered, and murdered peasants, marked the progress of these barbarians, under whose scourge the whole of Thuringia, Vogtland, and Meissen, lay defenceless.
Yet this was but the prelude to greater sufferings, with which Wallenstein himself, at the head of the main army, threatened Saxony.
After having left behind him fearful monuments of his fury, in his march through Franconia and Thuringia, he arrived with his whole army in the Circle of Leipzig, and compelled the city, after a short resistance, to surrender. His design was to push on to Dresden, and by the conquest of the whole country, to prescribe laws to the Elector.
