In 1792, as one of the most distinguished of the emperor's generals, he received the command of the Austrian contingent in army of the duke of Brunswick, and at Croix-sous-Bois his corps inflicted a reverse on the troops of the French Revolution. In the Netherlands, he commanded the center at the Battle of Jemappes on 6 November. He opened the campaign of 1793 with the victory of Aldenhoven and the relief of Maastricht, and on 18 March 1793 proved instrumental in causing the complete defeat of Charles Dumouriez at the Battle of Neerwinden. In October, however, his victorious career suffered a reverse at the Battle of Wattignies.
