Efforts by the French Revolutionary government to remove him from his command failed when his soldiers refused to give him up. A big, loud-voiced man, he led from the front of his troops. Although the failure of his cavalry to deploy at the Battle of Stockach (1799) resulted in a court martial, he was exonerated and went on to serve in the Swiss campaign in 1799, at the Second Battle of Stockach, the Battle of Biberach, and later at Battle of Hohenlinden. He served under Michel Ney and Joachim Murat. He was killed in Murat's massive cavalry charge of the Battle of Eylau in 1807.
