French general and marshal of France under Napoleon (1768-1835) who was made duke of Treviso in 1808. Two untranslated letters in French: an ALS signed “Ed: Mortier,” one page, 4.5 x 7.25, November 12, 1802; and an LS signed “Le Mal. Duc de Trevise,” one page, 7.75 x 9.5, Legion d'Honneur letterhead, June 18, 1834. In overall very good to fine condition, with some staining and paper loss to the central horizontal fold of one of the letters.
