The conditions, accordingly, upon which he offered to adopt the neutrality towards Bavaria were severe, and suited to these views. He required of the whole League a full and entire cessation from all hostilities; the recall of their troops from the imperial army, from the conquered towns, and from all the Protestant countries; the reduction of their military force; the exclusion of the imperial armies from their territories, and from supplies either of men, provisions, or ammunition. Hard as the conditions were, which the victor thus imposed upon the vanquished, the French mediator flattered himself he should be able to induce the Elector of Bavaria to accept them. In order to give time for an accommodation, Gustavus had agreed to a cessation of hostilities for a fortnight. But at the very time when this monarch was receiving from the French agents repeated assurances of the favourable progress of the negociation, an intercepted letter from the Elector to Pappenheim, the imperial general in Westphalia, revealed the perfidy of that prince, as having no other object in view by the whole negociation, than to gain time for his measures of defence. Far from intending to fetter his military operations by a truce with Sweden, the artful prince hastened his preparations, and employed the leisure which his enemy afforded him, in making the most active dispositions for resistance. The negociation accordingly failed, and served only to increase the animosity of the Bavarians and the Swedes.
Tilly's augmented force, with which he threatened to overrun Franconia, urgently required the king's presence in that circle; but it was necessary to expel previously the Spaniards from the Rhine, and to cut off their means of invading Germany from the Netherlands. With this view, Gustavus Adolphus had made an offer of neutrality to the Elector of Treves, Philip von Zeltern, on condition that the fortress of Hermanstein should be delivered up to him, and a free passage granted to his troops through Coblentz. But unwillingly as the Elector had beheld the Spaniards within his territories, he was still less disposed to commit his estates to the suspicious protection of a heretic, and to make the Swedish conqueror master of his destinies. Too weak to maintain his independence between two such powerful competitors, he took refuge in the protection of France. With his usual prudence, Richelieu profited by the embarrassments of this prince to augment the power of France, and to gain for her an important ally on the German frontier. A numerous French army was despatched to protect the territory of Treves, and a French garrison was received into Ehrenbreitstein. But the object which had moved the Elector to this bold step was not completely gained, for the offended pride of Gustavus Adolphus was not appeased till he had obtained a free passage for his troops through Treves.
Pending these negociations with Treves and France, the king's generals had entirely cleared the territory of Mentz of the Spanish garrisons, and Gustavus himself completed the conquest of this district by the capture of Kreutznach. To protect these conquests, the chancellor Oxenstiern was left with a division of the army upon the Middle Rhine, while the main body, under the king himself, began its march against the enemy in Franconia.
The possession of this circle had, in the mean time, been disputed with variable success, between Count Tilly and the Swedish General Horn, whom Gustavus had left there with 8,000 men; and the Bishopric of Bamberg, in particular, was at once the prize and the scene of their struggle. Called away to the Rhine by his other projects, the king had left to his general the chastisement of the bishop, whose perfidy had excited his indignation, and the activity of Horn justified the choice. In a short time, he subdued the greater part of the bishopric; and the capital itself, abandoned by its imperial garrison, was carried by storm. The banished bishop urgently demanded assistance from the Elector of Bavaria, who was at length persuaded to put an end to Tilly's inactivity. Fully empowered by his master's order to restore the bishop to his possessions, this general collected his troops, who were scattered over the Upper Palatinate, and with an army of 20,000 men advanced upon Bamberg. Firmly resolved to maintain his conquest even against this overwhelming force, Horn awaited the enemy within the walls of Bamberg; but was obliged to yield to the vanguard of Tilly what he had thought to be able to dispute with his whole army. A panic which suddenly seized his troops, and which no presence of mind of their general could check, opened the gates to the enemy, and it was with difficulty that the troops, baggage, and artillery, were saved. The reconquest of Bamberg was the fruit of this victory; but Tilly, with all his activity, was unable to overtake the Swedish general, who retired in good order behind the Maine. The king's appearance in Franconia, and his junction with Gustavus Horn at Kitzingen, put a stop to Tilly's conquests, and compelled him to provide for his own safety by a rapid retreat.
The king made a general review of his troops at Aschaffenburg. After his junction with Gustavus Horn, Banner, and Duke William of Weimar, they amounted to nearly 40,000 men. His progress through Franconia was uninterrupted; for Tilly, far too weak to encounter an enemy so superior in numbers, had retreated, by rapid marches, towards the Danube. Bohemia and Bavaria were now equally near to the king, and, uncertain whither his victorious course might be directed, Maximilian could form no immediate resolution. The choice of the king, and the fate of both provinces, now depended on the road that should be left open to Count Tilly. It was dangerous, during the approach of so formidable an enemy, to leave Bavaria undefended, in order to protect Austria; still more dangerous, by receiving Tilly into Bavaria, to draw thither the enemy also, and to render it the seat of a destructive war. The cares of the sovereign finally overcame the scruples of the statesman, and Tilly received orders, at all hazards, to cover the frontiers of Bavaria with his army.
Nuremberg received with triumphant joy the protector of the Protestant religion and German freedom, and the enthusiasm of the citizens expressed itself on his arrival in loud transports of admiration and joy. Even Gustavus could not contain his astonishment, to see himself in this city, which was the very centre of Germany, where he had never expected to be able to penetrate. The noble appearance of his person, completed the impression produced by his glorious exploits, and the condescension with which he received the congratulations of this free city won all hearts. He now confirmed the alliance he had concluded with it on the shores of the Baltic, and excited the citizens to zealous activity and fraternal unity against the common enemy. After a short stay in Nuremberg, he followed his army to the Danube, and appeared unexpectedly before the frontier town of Donauwerth. A numerous Bavarian garrison defended the place; and their commander, Rodolph Maximilian, Duke of Saxe Lauenburg, showed at first a resolute determination to defend it till the arrival of Tilly. But the vigour with which Gustavus Adolphus prosecuted the siege, soon compelled him to take measures for a speedy and secure retreat, which amidst a tremendous fire from the Swedish artillery he successfully executed.
The conquest of Donauwerth opened to the king the further side of the Danube, and now the small river Lech alone separated him from Bavaria. The immediate danger of his dominions aroused all Maximilian's activity; and however little he had hitherto disturbed the enemy's progress to his frontier, he now determined to dispute as resolutely the remainder of their course. On the opposite bank of the Lech, near the small town of Rain, Tilly occupied a strongly fortified camp, which, surrounded by three rivers, bade defiance to all attack. All the bridges over the Lech were destroyed; the whole course of the stream protected by strong garrisons as far as Augsburg; and that town itself, which had long betrayed its impatience to follow the example of Nuremberg and Frankfort, secured by a Bavarian garrison, and the disarming of its inhabitants. The Elector himself, with all the troops he could collect, threw himself into Tilly's camp, as if all his hopes centred on this single point, and here the good fortune of the Swedes was to suffer shipwreck for ever.
Gustavus Adolphus, after subduing the whole territory of Augsburg, on his own side of the river, and opening to his troops a rich supply of necessaries from that quarter, soon appeared on the bank opposite the Bavarian entrenchments. It was now the month of March, when the river
, swollen by frequent rains, and the melting of the snow from the mountains of the Tyrol, flowed full and rapid between its steep banks. Its boiling current threatened the rash assailants with certain destruction, while from the opposite side the enemy's cannon showed their murderous mouths. If, in despite of the fury both of fire and water, they should accomplish this almost impossible passage, a fresh and vigorous enemy awaited the exhausted troops in an impregnable camp; and when they needed repose and refreshment they must prepare for battle. With exhausted powers they must ascend the hostile entrenchments, whose strength seemed to bid defiance to every assault. A defeat sustained upon this shore would be attended with inevitable destruction, since the same stream which impeded their advance would also cut off their retreat, if fortune should abandon them.
The Swedish council of war, which the king now assembled, strongly urged upon him all these considerations, in order to deter him from this dangerous undertaking. The most intrepid were appalled, and a troop of honourable warriors, who had grown gray in the field, did not hesitate to express their alarm. But the king's resolution was fixed. "What!" said he to Gustavus Horn, who spoke for the rest, "have we crossed the Baltic, and so many great rivers of Germany, and shall we now be checked by a brook like the Lech?" Gustavus had already, at great personal risk, reconnoitred the whole country, and discovered that his own side of the river was higher than the other, and consequently gave a considerable advantage to the fire of the Swedish artillery over that of the enemy. With great presence of mind he determined to profit by this circumstance. At the point where the left bank of the Lech forms an angle with the right, he immediately caused three batteries to be erected, from which 72 field-pieces maintained a cross fire upon the enemy. While this tremendous cannonade drove the Bavarians from the opposite bank, he caused to be erected a bridge over the river with all possible rapidity. A thick smoke, kept up by burning wood and wet straw, concealed for some time the progress of the work from the enemy, while the continued thunder of the cannon overpowered the noise of the axes. He kept alive by his own example the courage of his troops, and discharged more than 60 cannon with his own hand. The cannonade was returned by the Bavarians with equal vivacity for two hours, though with less effect, as the Swedish batteries swept the lower opposite bank, while their height served as a breast-work to their own troops. In vain, therefore, did the Bavarians attempt to destroy these works; the superior fire of the Swedes threw them into disorder, and the bridge was completed under their very eyes. On this dreadful day, Tilly did every thing in his power to encourage his troops; and no danger could drive him from the bank. At length he found the death which he sought, a cannon ball shattered his leg; and Altringer, his brave companion-in-arms, was, soon after, dangerously wounded in the head. Deprived of the animating presence of their two generals, the Bavarians gave way at last, and Maximilian, in spite of his own judgment, was driven to adopt a pusillanimous resolve. Overcome by the persuasions of the dying Tilly, whose wonted firmness was overpowered by the near approach of death, he gave up his impregnable position for lost; and the discovery by the Swedes of a ford, by which their cavalry were on the point of passing, accelerated his inglorious retreat. The same night, before a single soldier of the enemy had crossed the Lech, he broke up his camp, and, without giving time for the King to harass him in his march, retreated in good order to Neuburgh and Ingolstadt. With astonishment did Gustavus Adolphus, who completed the passage of the river on the following day behold the hostile camp abandoned; and the Elector's flight surprised him still more, when he saw the strength of the position he had quitted. "Had I been the Bavarian," said he, "though a cannon ball had carried away my beard and chin, never would I have abandoned a position like this, and laid open my territory to my enemies."
Bavaria now lay exposed to the conqueror; and, for the first time, the tide of war, which had hitherto only beat against its frontier, now flowed over its long spared and fertile fields. Before, however, the King proceeded to the conquest of these provinces, he delivered the town of Augsburg from the yoke of Bavaria; exacted an oath of allegiance from the citizens; and to secure its observance, left a garrison in the town. He then advanced, by rapid marches, against Ingolstadt, in order, by the capture of this important fortress, which the Elector covered with the greater part of his army, to secure his conquests in Bavaria, and obtain a firm footing on the Danube.
Shortly after the appearance of the Swedish King before Ingolstadt, the wounded Tilly, after experiencing the caprice of unstable fortune, terminated his career within the walls of that town. Conquered by the superior generalship of Gustavus Adolphus, he lost, at the close of his days, all the laurels of his earlier victories, and appeased, by a series of misfortunes, the demands of justice, and the avenging manes of Magdeburg. In his death, the Imperial army and that of the League sustained an irreparable loss; the Roman Catholic religion was deprived of its most zealous defender, and Maximilian of Bavaria of the most faithful of his servants, who sealed his fidelity by his death, and even in his dying moments fulfilled the duties of a general. His last message to the Elector was an urgent advice to take possession of Ratisbon, in order to maintain the command of the Danube, and to keep open the communication with Bohemia.
With the confidence which was the natural fruit of so many victories, Gustavus Adolphus commenced the siege of Ingolstadt, hoping to gain the town by the fury of his first assault. But the strength of its fortifications, and the bravery of its garrison, presented obstacles greater than any he had had to encounter since the battle of Breitenfeld, and the walls of Ingolstadt were near putting an end to his career. While reconnoitring the works, a 24-pounder killed his horse under him, and he fell to the ground, while almost immediately afterwards another ball struck his favourite, the young Margrave of Baden, by his side. With perfect self-possession the king rose, and quieted the fears of his troops by immediately mounting another horse.
The occupation of Ratisbon by the Bavarians, who, by the advice of Tilly, had surprised this town by stratagem, and placed in it a strong garrison, quickly changed the king's plan of operations. He had flattered himself with the hope of gaining this town, which favoured the Protestant cause, and to find in it an ally as devoted to him as Nuremberg, Augsburg, and Frankfort. Its seizure by the Bavarians seemed to postpone for a long time the fulfilment of his favourite project of making himself master of the Danube, and cutting off his adversaries' supplies from Bohemia. He suddenly raised the siege of Ingolstadt, before which he had wasted both his time and his troops, and penetrated into the interior of Bavaria, in order to draw the Elector into that quarter for the defence of his territories, and thus to strip the Danube of its defenders.
The whole country, as far as Munich, now lay open to the conqueror. Mosburg, Landshut, and the whole territory of Freysingen, submitted; nothing could resist his arms. But if he met with no regular force to oppose his progress, he had to contend against a still more implacable enemy in the heart of every Bavarian -- religious fanaticism. Soldiers who did not believe in the Pope were, in this country, a new and unheard-of phenomenon; the blind zeal of the priests represented them to the peasantry as monsters, the children of hell, and their leader as Antichrist. No wonder, then, if they thought themselves released from all the ties of nature and humanity towards this brood of Satan, and justified in committing the most savage atrocities upon them. Woe to the Swedish soldier who fell into their hands! All the torments which inventive malice could devise were exercised upon these unhappy victims; and the sight of their mangled bodies exasperated the army to a fearful retaliation. Gustavus Adolphus, alone, sullied the lustre of his heroic character by no act of revenge; and the aversion which the Bavarians felt towards his religion, far from making him depart from the obligations of humanity towards that unfortunate people, seemed to impose upon him the stricter duty to honour his religion by a more constant clemency.
The approach of the king spread terror and consternation in the capital, which, stripped of its defenders,
and abandoned by its principal inhabitants, placed all its hopes in the magnanimity of the conqueror. By an unconditional and voluntary surrender, it hoped to disarm his vengeance; and sent deputies even to Freysingen to lay at his feet the keys of the city. Strongly as the king might have been tempted by the inhumanity of the Bavarians, and the hostility of their sovereign, to make a dreadful use of the rights of victory; pressed as he was by Germans to avenge the fate of Magdeburg on the capital of its destroyer, this great prince scorned this mean revenge; and the very helplessness of his enemies disarmed his severity. Contented with the more noble triumph of conducting the Palatine Frederick with the pomp of a victor into the very palace of the prince who had been the chief instrument of his ruin, and the usurper of his territories, he heightened the brilliancy of his triumphal entry by the brighter splendour of moderation and clemency.
The King found in Munich only a forsaken palace, for the Elector's treasures had been transported to Werfen. The magnificence of the building astonished him; and he asked the guide who showed the apartments who was the architect. "No other," replied he, "than the Elector himself." -- "I wish," said the King, "I had this architect to send to Stockholm." "That," he was answered, "the architect will take care to prevent." When the arsenal was examined, they found nothing but carriages, stripped of their cannon. The latter had been so artfully concealed under the floor, that no traces of them remained; and but for the treachery of a workman, the deceit would not have been detected. "Rise up from the dead," said the King, "and come to judgment." The floor was pulled up, and 140 pieces of cannon discovered, some of extraordinary calibre, which had been principally taken in the Palatinate and Bohemia. A treasure of 30,000 gold ducats, concealed in one of the largest, completed the pleasure which the King received from this valuable acquisition.
