General Mack had entered Ulm, and the emperor was still at Saint-Cloud. The movements of our troops were quietly going forward, when Napoleon conceived the idea of surrounding the enemy in Suabia by cutting off his communications with Austria. A note in his own handwriting, written on the 22nd of September, indicates beforehand the positions of all the corps of the army. On the 27th he arrived at Strasburg, prolonging his residence there in order to deceive the Austrian general, who kept his attention constantly fixed upon the Black Forest. On the 30th, at Strasburg, the emperor addressed to his troops a simple and firm proclamation, animated by that martial spirit which always inspired the army when he addressed it. "Soldiers, the war of the third coalition has commenced. The Austrian army has passed the Inn, broken the treaties, attacked our ally, and sent him from his capital. You yourselves have been compelled to hasten, by forced marches, to the defence of our frontiers. But already you have passed the Rhine. We will not stay our progress until we have assured the independence of the Germanic state, succored our allies, and confounded the pride of the unjust aggressors. We will have no more peace without a guarantee. Our generosity shall not again deceive our policy. Soldiers, your emperor is in the midst of you; you are only the vanguard of the great people. If it is necessary, they will rise as one man, to confound and dissolve this new league woven by the hatred and the gold of England. But, soldiers, we have forced marches to make, fatigues and privations of every kind to endure. Whatever obstacles maybe opposed to us we shall be victorious, and we will take no rest till we have planted our eagles upon the territory of our enemies."
Napoleon had said, "I reckon on making more use of the legs of my soldiers than even of their bayonets." The fatal circle was narrowing round General Mack by the rapid movements of the French troops, without his appearing to comprehend their aim, or divine the danger which threatened him. On the 8th of October he still wrote, that never had an army been posted in a manner more fitted to assure its superiority. On the same day, advancing upon Günzburg, Marshals Lannes and Murat encountered at Wutingen an Austrian corps, which was tardily marching to the succor of General Kienmayer, already dislodged from the bridges of the Danube and the Lech. The engagement was short and brilliant; the fugitives bore at length to Ulm the conviction of the overwhelming forces which menaced the Austrian army. The Emperor Napoleon had arrived at Donauwerth. The first bulletin from the Grand Army was dated October 7th, explaining all the military operations: "This grand and vast movement has carried us in a few days to Bavaria; has enabled us to avoid the Black Mountains, the line of parallel rivers which fall into the Danube, and the inconvenience of a system of operations which would have always had the defiles of the Tyrol on the flank; and lastly, has placed us several marches in the rear of the enemy, who has no time to lose, to avoid his entire destruction."
Napoleon was particularly watchful with respect to the Tyrol, for he had settled in his own mind that General Mack would seek an outlet on this side, to escape from the blockade with which he was menaced. The little German princes, terrified or won over, had submitted to the yoke of Napoleon, and accepted his alliance; the French troops had violated neutral territories with impunity; the Russian armies were at last making forced marches, and had just entered into Germany. At one moment Mack appeared to discover the feeble point in the enemy's line; the left bank of the Danube at Albech, was occupied by the divisions of Dupont and Baraguey d'Hilliers, insufficient for resisting a violent attack. Murat, who commanded the three divisions posted near Ulm, ordered Ney to recall all the troops posted on the left bank. The marshal was indignant and furious, but obeyed; but General Dupont had not accomplished his movement when he was assailed by a corps of 25,000 Austrians, commanded by the Archduke Ferdinand. The heroic resistance of the French troops enabled them to fall back upon Albech with 1500 prisoners. The enemy contented themselves with occupying the little town of Elchingen, and burning the bridge.
Napoleon had quitted Augsburg, and Marshal Soult had just effected the capitulation of Meiningen. The emperor ordered Ney to retake the positions of Elchingen. The piles of the bridge had not been burnt, and under the fire of the Austrians the platform was replaced, and the troops rushed forward to the attack on the village. The convent which crowned the height was taken at the bayonet's point. Always pushing the enemy before him, Ney seized upon the heights of Michelsberg; the fire of his cannons commanded the grand square in Ulm. The emperor in person had just arrived at the camp.
The Archduke Ferdinand had succeeded in escaping during the night. In spite of a frightful tempest he gained Biberach, and rejoined Wernek in Bohemia. Murat pursued him, while Marshal Soult occupied Biberach.
Henceforth Mack found himself without resources. "The general-in-chief was in the city," said the sixth bulletin of the grand army. "It is the destiny of generals opposed to the emperor to be taken in town. It will be remembered that after the splendid manoeuvres of the Brenta, the old Field-Marshal Wurmser was made prisoner at Mantua; Melas was taken in Alexandria; so is Mack in Ulm."
The emperor caused the Prince of Lichtenstein, major-general of the Austrian army, to be summoned. "I desire" said he "that the place capitulate; if I take it by assault, I shall he compelled to do what I did at Jaffa, where the garrison was put to the sword. It is the sad law of war. I desire that the necessity for such a frightful act should he spared to me, as well as to the brave Austrian nation. The place is not tenable."
Mack consented to surrender if he was not succored before the 25th of October. The rain fell in torrents. For eight days the emperor had not taken off his boots. The Austrian prisoners were astonished to see him, "soaked, covered with mud, as much fatigued as the lowest drummer in his army, and even more so." An aide-de-camp repeated to Napoleon the remarks of the enemy's officers. Napoleon replied quickly, "Your master has been desirous of making me remember that I am a soldier," said he. "I hope he will be convinced that the throne and the imperial purple have not made me forget my first business."
Wernek had laid down his arms at Nordlingen; the archduke was fleeing into Bohemia before the cavalry of Murat: the corps of Jellachich in the Tyrol, and that of Kienmayer beyond the Inn, could send no succors to General Mack. Urged to escape the horror of the situation, he forestalled the day fixed for the capitulation: on the 20th of October, 1805, the garrison at Ulm, which still counted 24,000 or 25,000 men, defiled slowly before the conqueror. The troops were prisoners of war, the cannons and flags had been abandoned; seven lieutenant-generals, eight generals, and the general-in-chief, Mack, kept at the emperor's side, were present with death in their souls at the ceremonial which proved their defeat. "In fifteen days we have finished a campaign," said the proclamation of Napoleon to his soldiers. "That which we proposed is completed. We have driven the troops of the House of Austria from Bavaria, and re-established our ally in the sovereignty of his States. That army which, with as much ostentation as imprudence, came forward to place itself on our frontiers, is annihilated. But what matters it to England? Her purpose is answered; we are not at Boulogne, and the subsidy which she grants to Austria will be neither larger nor smaller."
England resented the defeat of her ally more keenly than Napoleon acknowledged in the bitterness of his hate. The rumor of the capitulation of Ulm had reached London. On November 2nd, Lord Malmesbury was seated at table beside Pitt, and spoke to him of the rumors he had heard. "Don't believe a word of it; it is simply a lie," said Pitt, roughly, raising his voice so as to make himself heard by those around him. "But the next day, Sunday, the 3rd," continues Lord Malmesbury in his journal, "he entered my house with Lord Mulgrave, about one o'clock, and they brought with them a Dutch journal which contained at full length the capitulation of Ulm. Neither of them knew that language, and all the officials were away. I translated the article as well as I could, and I saw very clearly the effect that it produced upon Pitt, in spite of the efforts he made to hide it. This was the last time that I saw him. This visit left upon me a profound impression, his manners and countenance were so altered; I conceived from it, in spite of myself, the sad presentiment of the misfortune which threatened us."
