At the approach of the new French levies, Eugene Beauharnais retreated from Magdeburg, and joined them on the Saale. The Allies and Napoleon now lay face to face, the Allies cutting off his advance towards Leipsic and thence to Dresden. He resolved to make a determined attack upon them, and demoralise them by a blow which should make him master of Leipsic, Dresden, and Berlin at once, and give its impression to the whole campaign. In the skirmishes which took place previous to the general engagement at Weissenfels and Poserna on the 29th of April and the 1st of May, Buonaparte gained some advantages; but in the latter action his old commander of the Imperial Guard, Marshal Bessières, was killed. His death was deeply lamented, both by his men, who had served under him from the very commencement of Buonaparte's career, and by Buonaparte himself. The first great battle was destined to be fought on the very ground where Gustavus Adolphus fell, 1632. Buonaparte marched upon Leipsic, expecting to find the Allies posted there; but he was suddenly brought to a stand by them at Lützen. The Allies, who were on the left bank of the Elster, crossed to the right, and impetuously attacked the French, whose centre was at the village of Kaya, under the command of Ney, supported by the Imperial Guard, and their fine artillery drawn up in front of the town of Lützen; the right wing, commanded by Marmont, extending as far as the defile of Poserna, and the left stretching from Kaya to the Elster. Napoleon did not expect to have met the Allies on that side of Leipsic, and was pressing briskly forward when the attack commenced. Ney was first stopped at Gross-Görschen. Had Wittgenstein made a decided charge with his whole column, instead of attacking by small brigades, he would assuredly have broken the French lines. But Buonaparte rode up, and galloped from place to place to throw fresh troops on the point of attack, and to wheel up both of his wings so as to enclose, if possible, both flanks of the Allies. The conflict lasted some hours, during which it was uncertain whether the Allies would break the centre of the French, or the French would be able to outflank the Allies. Blucher was late on the field; the officer who was sent overnight to him with orders from Wittgenstein is said to have put them under his pillow and slept on them till roused by the cannon. At length, after a desperate attack by Napoleon to recover the village of Kaya, out of which he had been driven, the Allies observing that the firing of Macdonald and Bertrand, who commanded the two wings, was fast extending along their flanks, skilfully extricated themselves from the combat, and led back their columns so as to escape being outflanked by the French. Yet they did not even then give up the struggle for the day. The Allied cavalry made a general attack in the dark, but it failed from the mighty masses of the French on which they had to act. The Allies captured some cannon, the French none.
