The plan of the campaign is said to have been laid down by Bernadotte, and adopted, after some slight revision, by General Moreau. That general, whom the jealousy of Buonaparte had expelled from France, and who had retired to America, now returned in the hope of seeing the fall of Buonaparte effected, and peace and a liberal constitution given to his country. He came not to fight against France, but against Buonaparte. The plan showed that they who devised it knew Napoleon's art of war. It was to prevent him from attacking and beating them in detail. Whichever party was first assailed was to retire and draw him after them, till the other divisions could close round him, and assail him on all sides. Blucher was the first to advance against Macdonald and Ney. As had been foreseen, Buonaparte hastened to support these generals with the Imperial Guard and a numerous cavalry, under Latour-Maubourg. But Blucher then retired, and, crossing the Katzbach, sat down near Jauer, so as to cover Breslau. The purpose was served, for Schwarzenberg, accompanied by the sovereigns of Russia and Prussia, as well as by Moreau, had rushed forward on Dresden, driving St. Cyr and twenty thousand men before them, who took refuge in Dresden. The Allies were at his heels, and on the 25th of August began to attack the city. They hoped to win it before Buonaparte could return, in which case they would cut off his line of communication with France--stopping the advance both of his supplies and reinforcements. But the very next day, whilst they were in vigorous operation against the city, and had already carried two redoubts, Buonaparte was seen advancing in hot haste over the bridges into Dresden. Warned of its danger, he had left Macdonald to defend himself, and now led his troops across the city and out at two different gates upon the enemies. The battle continued that day, and was resumed the next, by Buonaparte pushing forward immense bodies of troops from different gates, and concentrating them on the Allies. The attempt to take the city in Buonaparte's absence had failed, and now they saw themselves in danger of being enclosed by Murat--who had again been induced to join the Emperor--on the Freiberg road, and by Vandamme on the road to Pirna, by the Elbe. They were, therefore, compelled to fall back, and the withdrawal soon proved a flight. Napoleon pursued them hotly amid torrents of wind and rain, and made great slaughter, especially of the Austrians, who were seized with a panic of the enemy who had so often beaten them. Seven or eight thousand French were killed and wounded; but of the Allies, chiefly Austrians, more than twenty thousand were killed or disabled. During the engagement Moreau had both his legs shot away by a cannon ball, and died in a few days. [Illustration: VIEW IN DRESDEN.]
