The emperor appeared moved; he, however, insisted on the dangers to which a sudden invasion would inevitably expose Louis XVI., he showed the letters of this prince, and intimated that the Marquis de Noailles and M. de Montmorin--the one French ambassador at Vienna, the other minister for Foreign Affairs at Paris, who were both devoted to the king--held out hopes to the court of Vienna of the speedy re-establishment of order and monarchical modifications of the constitution in France; and he demanded the right of suspending his decision until the month of September, although in the mean while military preparations should be made by both powers. The scene was changed the next morning by the Count d'Artois. This young prince had received from the hand of nature all the exterior qualifications of a chevalier: he spoke to the sovereigns in the name of the thrones; to the emperor in the name of an outraged and dethroned sister. The whole emigration, with its misfortunes, its nobility, its valour, its illusions, seemed personified in him. The Marquis de Bouille and M. de Calonne, the genius of war and the genius of intrigue, had followed him to these conferences. He obtained several audiences of the two sovereigns, he inveighed with respect and energy against the temporising system of the emperor, and violently roused the Germanic sluggishness. The emperor and the king of Prussia authorised the Baron de Spielman for Austria, the Baron de Bischofswerden for Prussia, and M. de Calonne for France, to meet the same evening, and draw up a declaration for the signature of the monarchs. The Baron de Spielman, under the immediate dictation of the emperor, drew up the document. M. de Calonne in vain combated, in the name of the Count d'Artois, the hesitation that disconcerted the impatience of the emigres. The next day, on their return from a visit to Dresden, the two sovereigns, the Count d'Artois, M. de Calonne, the Marechal de Lascy, and the two negotiators, met in the emperor's apartment, where the declaration was read and discussed, every sentence weighed, and some expressions modified; and at the proposal of M. de Calonne, and the entreaties of the Count d'Artois, the emperor and the king of Prussia consented to the insertion of the last phrase, that threatened the Revolution with war. Subjoined is the document that was the date of a war of twenty-two years' duration.
