From the 24th of September till the commencement of October Buonaparte continued to maintain himself at Dresden, though the Allies were fast gathering round him. Occasionally he made a rush from the city, and on one occasion pursued Blucher as far as Nollendorf, beyond Kulm; but these expeditions only served to exhaust his troops, without producing any effect on the enemy. As he chased one body on one side, others were closing up on other sides. Seeing that he could not remain long at Dresden, and that Bernadotte and Bülow had quitted the neighbourhood of Berlin, he suddenly conceived the design of marching rapidly on that city, and taking up his headquarters there; but this scheme met with universal disapprobation from his officers, and he was compelled to abandon it. He then continued for days, and even weeks, in a state of listless apathy, for hours together mechanically making large letters on sheets of paper, or debating some new schemes with his generals; but the only scheme to which they would listen was that of retreating to the left bank of the Rhine. In fact, they and the army were completely worn out and dispirited. The Allies now determined to close in on all sides, and compel the French to a surrender. But Buonaparte, after some manœuvres to bring Blucher to action--that general and the Crown Prince of Sweden having crossed to the left bank of the Elbe--found it at length necessary to retreat to Leipsic. He reached that city on the 15th of October, and learned, to his great satisfaction, that whilst his whole force would be under its walls within twenty-four hours, the Austrians were advancing considerably ahead of the Prussians; and he flattered himself that he should be able to beat the Austrians before the other Allies could reach them.
