In reality, the King did not desire war, but the bellicose current had become irresistible. The court of Vienna had shown itself intractable. It forbade the princes who owned possessions in Lorraine and Alsace to receive the indemnities offered by France in exchange for their feudal rights, and threatened to have the Diet of Ratisbonne annul any private treaties they might conclude concerning them. The electors of Trèves, Cologne, and Mayence undisguisedly favored the levying of troops by the emigrant {127} princes, and even paid subsidies toward their support. They refused to recognize the official ambassadors of Louis XVI., while recognizing the plenipotentiaries of these princes. There was talk of holding a Congress at Aix-la-Chapelle for the purpose of intimidating the National Assembly. The successor of the Emperor Leopold, Francis II., who, before his election to the Empire, had assumed the title of King of Hungary and Bohemia, displayed extremely martial sentiments. Austria, which had sent forty thousand men to the Low Countries and twenty thousand to the Rhine, had just signed a treaty of alliance with Prussia, "to put an end to the troubles in France." Dumouriez urgently demanded the court of Vienna to explain itself. It finally sent the French Ambassador, Marquis de Noailles, a dry, curt, and formal note, naming the only conditions on which peace could be preserved. These were: the re-establishment of the French monarchy on the bases of the royal declaration of June 23, 1789, and, consequently, the restoration of the nobility and clergy as orders; the restitution of Church property; the return of Alsace to the German princes, with all their sovereign and feudal rights; and, finally, the surrender of Avignon and the county of Venaisson to the Holy See.
