Immediately after this engagement Blucher was joined by part of the grand army, under the Prince of Würtemberg; he therefore determined to attack Napoleon, and on the 1st of February drew out his forces. Napoleon would have declined the engagement; but he had the deep river Aube in his rear, and only the bridge of Lesmont by which to pass it. He preferred, on this account, to risk the battle, rather than retreat in such circumstances. Blucher attacked at once from the villages of La Rothière, Dienville, and Chaumont. The battle was severely contested for the whole day, the Prince of Würtemberg greatly distinguishing himself in it. In the end Buonaparte was wholly defeated, lost four thousand prisoners and seventy-three guns, and must have been captured himself, had not the Austrians, by surprising slowness, allowed him to escape over the bridge. He then retreated towards Troyes, where he was joined by his Imperial Guard; but his losses had been very heavy. Had Blucher and Schwarzenberg, who had now met, marched on united, they must have been in Paris in a very short time; but, with the German fatality of dividing, they had no sooner experienced the benefit of a powerful union than they called a council at the château of Brienne, and agreed to separate again. Blucher, joining to his own the divisions of Yorck and Kleist, proceeded towards Paris by the Marne, and Prince Schwarzenberg followed the course of the Seine. Buonaparte saw his opportunity, and, making a movement by a body of troops on Bar-sur-Seine, he alarmed Schwarzenberg, who thought he was intending to attack him in full force, and therefore changed his route, separating farther from Blucher. This point gained, Buonaparte marched after Blucher. That general had driven Macdonald from Château Thierry, and had established his headquarters at Vertus. Sacken was in advance as far as Ferté-sous-Jouarre, and Yorck at Meaux, much nearer Paris than Buonaparte himself. Paris was in great alarm. But Napoleon, taking a cross-country road, and dragging his artillery by enormous exertions over hedges, ditches, and marshes, came upon Blucher's rear, to his astonishment, at Champaubert. Driving in the Russians, Napoleon defeated him, taking two thousand prisoners, and most of his artillery; and being thus posted between Sacken and Blucher, he first attacked and defeated Sacken, destroying or squandering five thousand men--about one-fourth of his division--and then turned to attack Blucher himself, who was marching rapidly up to support Sacken. Blucher, finding himself suddenly in face of the whole army of Buonaparte, in an open country, fell back, but conducted his retreat so admirably that he cut his way through two strong bodies of French, who had posted themselves on the line of his march, and brought off his troops and artillery safe to Châlons. Napoleon then turned against Schwarzenberg, and on the 17th of February he met and defeated him at Nangis. Such were the immediate
