The aged Kutusoff having died, the command of the Russian army was now given to Witgenstein; while that of the Prussians was entrusted to a leader, whose name was hailed as the sure pledge of unremitting activity and indomitable perseverance. This was Blucher, an officer originally trained under the great Frederick, whose exemplary conduct after the battle of Jena has already been mentioned. The brave old man had, since that catastrophe, lived in utter retirement. The soldiery had long before bestowed on him the nom-de-guerre of Marshal Forwards, and they heard of his appointment with universal delight. Addicted to drinking, smoking, and gambling, and little conversant with the higher branches of war as an art, Blucher was at first despised by Napoleon. But his technical deficiencies were abundantly supplied by the skill of Scharnforst, and afterwards of Gneisenau; and he himself possessed such influence over the minds of his men in the day of action, and was sure to rally them so rapidly after defeat, and to urge them on so keenly when fortune was more favourable, that ere long the Emperor was forced to confess that no one gave him so much trouble as that "debauched old dragoon." Blucher hated the very names of France and Buonaparte with a perfect hatred; and, once more permitted to draw his sword, he swore never to sheathe it until the revenge of Prussia was complete.

The Crown Prince of Sweden landed with 35,000 men at Stralsund, and advanced through Mecklenburg, while the sovereigns of Russia and Prussia were concentrating their armies in Silesia. It was announced and expected that German troops would join Bernadotte, so as to enable him to open the campaign on the lower Elbe with a separate army of 100,000. Lord Wellington was about to advance once more into Spain, with his victorious veterans. Three great armies, two of which might easily communicate with each other, were thus taking the field against him at once; and yet, such was Napoleon's pride or obstinacy, that he would make no sacrifice whatever to secure the assistance of Austria. He still adhered to his resolution of entering into no general peace which should not recognise Joseph as King of Spain; and refused absolutely to listen to any proposals which included the cession either of Illyria or the Tyrol. Ere he once more left Paris, he named Maria Louisa Regent in his absence; but this was a circumstance not likely to have much weight with the wavering counsels of the Austrian.

While Napoleon's military preparations were in progress, he made an effort to conciliate that large party of his subjects, who had hitherto looked on him with coldness as the oppressor of the head of the Catholic church. During his absence in Russia, the Pope had been removed once more to Fontainebleau, where he now occupied apartments in the palace, under strict surveillance of the police. The Emperor presented himself suddenly in his hunter's dress before the holy father on the 13th of January; and exerted his talents with such success, that preliminary articles of a new concordat were at length drawn up. But in his eagerness to produce a favourable impression on the Catholic public, Napoleon published these preliminary articles, as if they had formed a definite and ratified treaty; and Pius, indignant at this conduct, which he considered as equally false and irreverent, immediately announced his resolution to carry the negotiation no further.

The Pope, however, was the only man in France who as yet durst openly confront the rage of Buonaparte. As the time when he was expected to assume once more the command of his army in the field drew near, the addresses of his apparently devoted subjects increased in numbers, and still more in the extravagance of their adulations.

Napoleon quitted Paris in the middle of April, and on the 18th reached the banks of the Saale; where the troops he had been mustering and organising in France had now been joined by Eugene Beauharnois and the garrison of Magdeburg. The Czar and his Prussian ally were known to be at Dresden; and it soon appeared that, while they meditated a march westwards on Leipsig, the French intended to move eastwards with the view of securing the possession of that great city. Of the armies thus about to meet each other's shock in the heart of Saxony, there is no doubt that Buonaparte's was considerably the more numerous. His activity had been worthy of his reputation; and a host nearly 200,000 strong was already concentrated for action, while reserves to nearly a similar extent were gradually forming behind him on the Rhine. The Russians had not as yet pushed forward more than half their disposable troops beyond the Vistula—wherever the blame lay, such was the fact; the Prussians, unanimous as their patriotism was, had had only three months to reorganise their establishments. Under such circumstances, the advance of the allies beyond the Elbe, could only have proceeded from their ardent wish to stimulate the spirit of insurrection in the kingdom of Saxony and the neighbouring states. It was obviously Napoleon's interest to bring them to action while their numbers were thus unequal, and ere the sole object of their hazardous advance could be realised.

The armies met sooner than he had ventured to hope, on the first of May, near the town of Lutzen, celebrated already as the scene of the battle in which King Gustavus Adolphus died. The allies crossed the Elster suddenly, under the cover of a thick morning fog, and attacked the left flank of the French, who had been advancing in column, and who thus commenced the action under heavy disadvantages. But the Emperor so skilfully altered the arrangement of his army, that, ere the day closed, the allies were more afraid of being enclosed to their ruin within his two wings, than hopeful of being able to cut through and destroy that part of his force which they had originally charged and weakened, and which had now become his centre. Night interrupted the conflict. They retreated next morning, leaving Napoleon in possession of the field. But here the advantage stopped. The slain of the one army were not more numerous than those of the other; and the allies, convinced of their mistake, but neither broken nor discouraged, fell back leisurely on Leipsig, thence on Dresden, and finally across the Elbe to Bautzen, without leaving either prisoners or guns in the hands of the French. The victory of Lutzen was blazoned abroad, as having restored all its glory to the eagle of Napoleon; but he clearly perceived that the days were no more in which a single battle determined the fate of a campaign, and an empire. It was at Lutzen that Marshal Bessieres died.

Napoleon entered Dresden on the 6th, and on the 12th was joined there by the King of Saxony, who certainly had been individually a gainer by his alliance, and who still adhered to it, in opposition to the wishes both of his people and his army. The Saxon troops, who had been wavering, once more submitted to act in concert with the French; and Hamburg, which city had partaken in the movement of Prussia, and all the country to the left of the Elbe, fell back, for the moment, into their hands. The cruelty with which the defection of Hamburg, in particular, was now revenged on the inhabitants by Marshal Davoust, has consigned to lasting abhorrence the name of that able but heartless satellite of Napoleon. All the atrocities of Junot and Massena, in Portugal, in 1808 and 1809, were equalled on the banks of the Elbe, by Davoust, in the summer of 1813.

While the Emperor paused at Dresden, Ney made various demonstrations in the direction of Berlin, with the view of inducing the allies to quit Bautzen; but it soon became manifest that they had resolved to sacrifice the Prussian capital, if it were necessary, rather than forego their position; by adhering to which they well knew Buonaparte must ultimately be compelled to carry his main force into a difficult and mountainous country, in place of acting in the open plains of Saxony and Brandenburg. They were, moreover, desirous to remain in the neighbourhood of Bohemia for another reason. The Austrian Emperor had again renewed his negotiation with Napoleon; urging him to accept his mediation for the conclusion of a general peace, and at the same time giving him to understand that such a peace could not be obtained, unless he would consent to be satisfied with the frontier of the Rhine, and restore effectively the independence of the German nation. Napoleon's conferences with Bubna, the Austrian envoy, were frequent and long; but they ended where they began. He was well aware, however, that the Emperor Francis was increasing his military establishment largely, and that a great body of troops was already concentrated behind the mountainous frontier of Bohemia. He could not but see that Austria regarded herself as enabled and entitled to turn the scale on whichsoever side she might choose; and he determined to crush the army which had retreated from Lutzen, ere the ceremonious cabinet of Vienna should have time to come to a distinct understanding with the headquarters of Alexander and Frederick William. Victory, he clearly saw, could alone serve his interests with the Austrian.

Having replaced by woodwork some arches of the magnificent bridge over the Elbe, at Dresden, which the allies had blown up on their retreat, Napoleon now moved towards Bautzen, and came in sight of the position on the morning of the 21st of May. Its strength was obviously great. In their front was the river Spree: wooded hills supported their right, and eminences well fortified their left. The action began with an attempt to turn their right, but Barclay de Tolly anticipated this movement, and repelled it with such vigour, that a whole column of 7000 dispersed and fled into the hills of Bohemia for safety. The Emperor then determined to pass the Spree in front of the enemy, and they permitted him to do so, rather than come down from their position. He took up his quarters in the town of Bautzen, and his whole army bivouacked in presence of the allies. The battle was resumed at daybreak on the 22nd; when Ney on the right, and Oudinot on the left, attempted simultaneously to turn the flanks of the position; while Soult and Napoleon himself directed charge after charge on the centre. During four hours the struggle was maintained with unflinching obstinacy; the wooded heights, where Blucher commanded, had been taken and retaken several times—the bloodshed, on either side, had been terrible—ere, the situation of both flanks being apparent, the allies perceived the necessity either of retiring, or of continuing the fight against superior numbers on disadvantageous ground. They withdrew accordingly; but still with all the deliberate coolness of a parade: halting at every favourable spot, and renewing their cannonade. "What," exclaimed Napoleon, "no results! not a gun! not a prisoner!—these people will not leave me so much as a nail." During the whole day he urged the pursuit with impetuous rage, reproaching even his chosen generals as "creeping scoundrels," and exposing his own person in the very hottest of the fire. By his side was Duroc, the grand master of the palace, his dearest—many said, ere now, his only friend. Bruyeres, another old associate of the Italian wars, was struck down in their view. "Duroc," whispered Napoleon, "fortune has a spite at us this day." A few minutes afterwards, Duroc himself was mortally wounded. The Emperor instantly ordered a halt, and remained all the afternoon in front of his tent, surrounded by the guard, who did not witness his affliction without tears. From this time he would listen to no reports or suggestions.—"Everything to-morrow," was his invariable answer. He stood by Duroc while he died; drew up with his own hand an epitaph to be placed over his remains by the pastor of the place, who received 200 napoleons to defray the expense of a fitting monument; and issued also a decree in favour of his departed friend's children. Thus closed the 22nd. The allies being strongly posted during most of the day, had suffered less than the French; the latter had lost 15,000, the former 10,000 men.

They continued their retreat into Upper Silesia; and Buonaparte advanced to Breslau, and released the garrison of Glogau. Meanwhile the Austrian having watched these indecisive though bloody fields, once more renewed his offers of mediation. The sovereigns of Russia and Prussia expressed great willingness to accept it; and Napoleon also appears to have been sincerely desirous for the moment of bringing his disputes to a peaceful termination. He agreed to an armistice, and in arranging its conditions agreed to fall back out of Silesia; thus enabling the allied princes to re-open communications with Berlin. The lines of country to be occupied by the armies, respectively, during the truce, were at length settled, and it was signed on the 1st of June. The French Emperor then returned to Dresden, and a general congress of diplomatists prepared to meet at Prague.
