Napoleon landed in the Gulf of Juan, and his rapid march upon Paris excited the greatest alarm in the Congress of Vienna. The activity of the French ambassador redoubled its vehemence, for Napoleon had outlawed him in his decrees dated from Lyons, and he in his turn revenged himself by causing Buonaparte to be placed at the ban of the empire. He took great pains to obtain this result, the declaration of the Congress of Vienna was his work, and it was he that induced Lord Castlereagh and Metternich to sign it. From this moment the coalition was in motion, and France was again threatened with an irruption of myriads of armed men, when the battle of Waterloo a second time terminated the sway of Napoleon. When a power is at an end, all attempts to restore it are in vain, it is merely the flash that precedes the extinction of an expiring light. Talleyrand returned to Paris with the Bourbons, but his authority was no longer what it had been. Louis XVIII. had discovered that his plenipotentiary, and the Duc de Dalberg, in his name, had received overtures concerning the possibility of the younger branch of the Bourbons succeeding to the throne of France, and it was not likely he should forget it. The king, with his habitual sagacity and experience, would never have chosen for his minister the man who had been plenipotentiary at Vienna; but the influence of the Duke of Wellington, which placed Fouché at the head of the police, also restored to Talleyrand the direction of foreign affairs. The cabinet of July 1815 was entirely favourable to English ideas and interests.
