The Duke of Candale, of whom Saint-Évremond has left a very severe portrait, gave him a command in Guienne after he had reached the grade of maréchal de camp, and he is said to have pocketed 50,000 livres in less than three years from this office.

His letter to Marshal Créquy on the Treaty of the Pyrenees, which is said to have been discovered by Colbert's agents at the seizure of Fouquet's papers, seems a very inadequate cause for his disgrace.

He died aged ninety on 9 September 1703[2] and was buried in Westminster Abbey, where his monument is in Poets' Corner, close to that of Prior.

His masterpiece in irony is the so-called Conversation du maréchal d'Hocquincourt avec le père Canaye (the latter a Jesuit and Saint-Évremond's master at school), which has been frequently classed with the Lettres provinciales.

His correspondence with Ninon de l'Enclos, whose fast friend he was, was published in 1752; La Comédie des académistes, written in 1643, was printed in 1650.
