In June 1793, Turreau was brought into the Army of the coasts of La Rochelle, remaining so until 8 October though the post did not please him. He wrote to a friend, "I would move heaven and earth not to go to Poitou. This kind of war displeases me." Even so, he fought for two months in the Vendée. He served as head of the Army of the Eastern Pyrenees from 12 October until 27 November 1793. During that period, he was defeated by Spanish General Antonio Ricardos at the Battle of the Tech (Pla-del-Rey) on 13–15 October. In January 1794, he denounced fellow general Eustache Charles d'Aoust to the Committee of Public Safety, leading to d'Aoust's execution in July. He became commander in chief of the Armée de l'Ouest from 29 December, but he again regarded this post with little enthusiasm. Before he arrived at his post, the last elements of the Armée catholique et royale were erased by Jean-Baptiste Kléber and François Séverin Marceau at the Battle of Savenay on 23 December.
