There he conducted the negotiations in regard to the marriage of Napoleon with the archduchess Maria Louisa. He gave a ball in honor of it, which was broken up by a terrible conflagration resulting in the death of his sister-in-law the princess Pauline of Schwarzenberg, and the empress barely escaped with her life. In the campaign of 1812 against Russia, he commanded the Austrian contingent of the French army; and at the request of Napoleon the emperor Francis created him a marshal.

After his return he received the supreme command of the allied troops of Russia, Austria, and Prussia, gained the victory of Leipsic, and marched to Paris. On the return of Napoleon from Elba he received the command of the allied army on the upper Rhine, and a second time entered France after the battle of Waterloo. At the end of the campaign he was made president of the imperial military council, and was presented with several estates in Hungary.
