Chabert was sent to Spain as a brigade commander in 1808. When Pierre Dupont de l'Etang's corps was surrounded after the Battle of Bailén, Chabert was one of the French generals who negotiated the capitulation. For this, Napoleon threw him in prison after the Spanish released him. After some time, he was released but remained unemployed and watched by the police. Yet, in 1809 he was appointed Baron of the Empire. In 1814 Chabert volunteered his services and fought at Saint-Julien. During the Hundred Days Napoleon promoted him general of division and appointed him to lead the 5th National Guard Division in Marshal Louis Gabriel Suchet's corps in the Alps. Under the Bourbon Restoration he was demoted. His surname is one of the names inscribed under the Arc de Triomphe, on Column 26.
