In 1823, the French Spanish Expedition was formed to invade the Kingdom of Spain and dispose the Trienio Liberal in support of King Ferdinand VII. As part of this expedition, the regiment was mobilised on 8 February 1823 when it left its station in Épinal for Bayonne. At the end of March, the regiment joined the Reserve Corps under command of General Étienne Tardif de Pommeroux, Comte de Bordesoulle. As the campaign began, the regiment was based around Orthez originally, later crossing the Bidasoa on 27 April. As the campaign progressed, the regiment was based in several towns including many which former soldiers resented the names of, like Vitoria, Burgos, Valladolid, and Madrid, and finally Toledo towards the end of May. Following the end of the successful invasion, the army was withdrawn via Madrid, Talavera, and Aranjuez before finally returning to Bayonne never seeing any major combat.
