wife and two children, Marie Françoise, born November 28, 1731, and Jean-François, baptized in New Orleans on January 2, 1733. He took up residence in Port-Louis, Morbihan, the port from which he had sailed to Louisiana. As captain of the gates in the citadel of Port-Louis, he again quarreled with his superior officers. In 1747, he wrote out a 443-page memoir of his life, dedicated to Belle-Isle. By 1750, he was back in Paris, developing a reputation as an expert on Louisiana by drawing maps and publishing essays in learned journals. It appears that he may have collaborated with Antoine-Simon Le Page du Pratz, who published a series of articles on Louisiana in the Journal Œconomique, a periodical devoted to science and commercial topics. Dumont also published two brief pieces in the journal and wrote a book about his experiences in the New World, Mémoires historiques sur la Louisane. Dumont's book relates one of the two earliest accounts of Moncacht-Apé's journey across North America; the other is in Le Page du Pratz's Histoire de la Louisiane. After publishing his book, Dumont obtained another commission as a lieutenant in the colonial Company of the Indies, and he sailed in 1754 with his wife for Mauritius and then to Pondicherry, a French outpost in India. He died there in 1760. References Further reading By Dumont de Montigny De Montigny, Dumont. Historical Memoirs of M. Dumont de Montigny in B. F. French, ed.
