He lingered at Dresden at least three weeks after all rational hope of holding that river was gone; and even at the last, when he perceived the necessity of transferring his person to Leipsig, he could not be persuaded to call in his garrisons scattered down the valley, which he still hoped some turn of events would enable him to revisit in triumph.
Towards Leipsig, however, as on a common centre, the forces of France, and all her enemies, were now at length converging. Napoleon reached that venerable city on the 15th of October, and almost immediately the heads of Schwartzenberg's columns began to appear towards the south. It was necessary to prepare on the northern side also, in case Bernadotte and Blucher should appear ere the grand army was disposed of; and, lastly, it was necessary to secure effectually the ground to the west of Leipsig;—a series of marshy meadows interfused with the numerous branches of the Pleiss and the Elster, through which lies the only road to France. Napoleon having made all his preparations, reconnoitred every outpost in person, and distributed eagles, in great form, to some new regiments which had just joined him. The ceremonial was splendid: the soldiers knelt before the Emperor, and in presence of all the line: military mass was performed, and the young warriors swore to die rather than witness the dishonour of France. Upon this scene the sun descended; and with it the star of Napoleon went down for ever.
At midnight three rockets, emitting a brilliant white light, sprung into the heavens to the south of the city; these marked the position on which Schwartzenberg (having now with him the Emperor of Austria, as well as Alexander and Frederick William) had fixed his headquarters. They were answered by four rockets of a deep red colour, ascending on the instant from the northern horizon; and Napoleon doubted not that he was to sustain on the morrow the assault of Blucher and Bernadotte, as well as of the grand army of the Allies. Blucher was indeed ready to co-operate with Schwartzenberg; and though the Crown Prince had not yet reached his ground, the numerical superiority of the enemy was very great. Buonaparte had with him, to defend the line of villages to the south and north of Leipsig, 136,000 men; while, even in the absence of Bernadotte, who might be hourly looked for, the Allies mustered not less than 230,000.
The battle commenced on the southern side, at daybreak of the 16th. The Allies charged the French line there six times in succession, and were as often repelled. Napoleon then charged in his turn, and with such effect, that Murat's cavalry were at one time in possession of a great gap between the two wings of the enemy. The Cossacks of the Russian imperial guard, however, encountered the French horse, and pushed them back again. The combat raged without intermission until nightfall: three cannon shots, discharged at the extremity of either line, then marked as if preconcertedly, the pause of battle; and both armies bivouacked exactly where the morning light had found them. Such was the issue on the south, where Napoleon himself commanded. Marmont, his lieutenant on the northern side, had been less fortunate. Blucher attacked him with a vast superiority of numbers: nothing could be more obstinate than his defence; but he lost many prisoners and guns, was driven from his original ground, and occupied, when the day closed, a new line of positions, much nearer the walls of the city.
Gallant as the behaviour of his troops had been, the result satisfied Napoleon that he must finally retreat from Leipsig; and he now made a sincere effort to obtain peace. General Mehrfeldt, the same Austrian officer who had come to his headquarters after the battle of Austerlitz, to pray for an armistice on the part of the Emperor Francis, had been made prisoner in the course of the day, and Napoleon resolved to employ him as his messenger. Mehrfeldt informed him that the King of Bavaria had at length acceded to the alliance. This intelligence added to his perplexities, already sufficiently great, the prospect of finding a new enemy stationed on the line of his march to France. He entreated the Austrian to request for him the personal intercession of Francis. "I will renounce Poland and Illyria," said he, "Holland, the Hanse Towns, and Spain. I will consent to lose the sovereignty of the kingdom of Italy, provided that state remain as an independent one—and I will evacuate all Germany. Adieu! Count Mehrfeldt, when on my part you name the word armistice to the two Emperors, I doubt not the sound will awaken many recollections."
It was now too late: the Allied Princes had sworn to each other to entertain no treaty while one French soldier remained on the Eastern side of the Rhine. Napoleon received no answer to his message; and prepared for the difficult task of retreating with 100,000 men, through a crowded town, in presence of an enemy already twice as numerous, and in early expectation of being joined by a third great and victorious army.
During the 17th the battle was not renewed, except by a distant and partial cannonade. The Allies were resolved to have the support of Bernadotte in the decisive contest.
At eight in the morning of the 18th it began, and continued until nightfall without intermission. Buonaparte had contracted on the south, as well as on the north, the circuit of his defence; and never was his generalship, or the gallantry of his troops, more brilliantly displayed than throughout this terrible day. Calm and collected, the Emperor again presided in person on the southern side, and again, where he was present, in spite of the vast superiority of the enemy's numbers, the French maintained their ground to the end. On the north, the arrival of Bernadotte enabled Blucher to push his advantages with irresistible effect; and the situation of Marmont and Ney (now also stationed on that side) was further perplexed by the shameful defection of 10,000 Saxons, who went over with all their artillery to the enemy, in the very midst of the battle. The two marshals, therefore, were compelled to retire from point to point, and at nightfall lay almost close to the walls of Leipsig. Three cannon shot, as before, marked the general termination of the battle.
The loss on either side had been great. Napoleon's army consisted chiefly of very young men—many were merely boys—the produce of his forestalled conscriptions: yet they fought as bravely as the guard. The behaviour of the Germans, on the other hand, at length considering their freedom and independence as hanging on the fortune of a single field, had been answerable to the deep enthusiasm of that thoughtful people. The burghers of Leipsig surveyed from their towers and steeples one of the longest, sternest, and bloodiest of battles: and the situation of the King of Saxony, who remained all the while in the heart of his ancient city, may be imagined.
Napoleon gave orders at midnight for the commencement of the inevitable retreat; and while the darkness lasted, the troops continued to file through the town, and across the two bridges, over the Pleisse, beyond its walls. One of these bridges was a temporary fabric, and it broke down ere daylight came to show to the enemy the movement of the French. The confusion necessarily accompanying the march of a whole army, through narrow streets and upon a single bridge, was fearful. The Allies stormed at the gates on either side, and, but for the heroism of Macdonald and Poniatowski, to whom Napoleon entrusted the defence of the suburbs, it is doubted whether he himself could have escaped in safety. At nine in the morning of the 19th, he bade farewell for ever to the King of Saxony, who remained to make what terms he could with the allied sovereigns. The battle was ere then raging all round the walls.
