In 1823, captaining the frigate "Guerrière", he cruised off Spain during the invasion by the Hundred Thousand Sons of Saint Louis. On 9 August, he was sent off Algeciras with "Galathée", taking part in the capture of the city, and later in the capture of Cadix. At the end of the campaign, he was promoted to contre-amiral and made a Baron in reward of his conduct.
