In 1816, Moncey was given back his title of marshal by the king and he re-entered the Chamber of Peers three years later. He continued his military career as his last active service was as commander of an army corps in the short war with Spain in 1823. From 1833 to 1842, Moncey became governor of the prestigious Hôtel des Invalides (a home for veterans in Paris). Present at the return of Napoleon's remains in December 1840, he said after the ceremony, "Now, let's go home to die".
