As part of Pierre Anton Courtot's eighth division at Mainz on 29 October 1795, he was under the command of Pierre Marie Barthélemy Ferino in the Army of the Rhine and Moselle on 30 December 1795 and Guillaume Philibert Duhesme's sixth division in April 1796. As commander at Landau on 27 April 1796, he crossed the Rhine to watch Philippsburg on 19 July 1796. Throughout the summer of 1796 he remained at Bruchsal, responsible for observation of the garrisons of Mannheim and Philippsburg. In September 1796, it appeared that he would be cut off from the corps of Jean-Baptiste Jourdan, which was retreating toward France north of the Mainz, and Jean Victor Marie Moreau, who was retreating through the Black Forest; he withdrew toward Kehl. During the withdrawal he skirmished with Franz Petrasch until he was cut off from Kehl by the Austrian corps.
