In it, he wrote radical denunciations of counter-revolutionaries much like those written by Jean-Paul Marat and Camille Desmoulins, and in fact the three of them aided each other in editing their papers.

Soon after, he was elected as representative to the Bonne-Nouvelle district of the newly formed Paris Commune, where it seems he was minimally active before returning to his role as a journalist.

He acted as a collaborator for L’Ami des citoyens for a brief period before starting his own paper L'Orateur du Peuple, under the pseudonym Martel, which consisted of 8 pages and was distributed every other day, with Marcel Enfantin serving as editor.

Nonetheless, both he and Barras joined the Thermidorian Reaction in its clash with Robespierre; L'Orateur du Peuple became the mouthpiece of anti-Jacobins, and Fréron incited the Muscadins to attack the sans-culottes with clubs.

General Charles Leclerc, who had married Pauline Bonaparte, also received a command in Saint Domingue in 1801 (during the last stage of the Haitian Revolution), and died the same year.
