Louis Antoine Juchereau de St. Denis, a settler in New France, was only ten years old when René-Robert Cavelier, Sieur de La Salle met his violent end in the woods of East Texas. Even so, this event would chart the course of his life.
As the young Saint Denis grew toward manhood, his parents shipped him to France to complete his education. By 1699, at age twenty-four, St. Denis held a commission in the army and led a company of troops. He joined the command of Pierre Le Moyne, Sieur d’Iberville gathering at La Rochelle heading to La Louisiane to consolidate French control over the lower Mississippi River. There, St. Denis managed outposts on the great river as well as Biloxi Bay before leading expeditions that contacted the Caddos and Karankawas in Spanish Tejas. Two of his soldiers, Pierre and John-Baptiste Talon, survivors of La Salle’s expedition, proved invaluable as guides and translators.
By 1714, St. Denis had established a trading post, Fort St. Jean Baptiste de Natchitoches, on the Red River. From here, the intrepid Frenchman continued his inroads among the Caddoan nations before pushing on to the Spanish settlements springing up on the Rio Grande in response to the French presence on the Red River. St. Denis, guided by two of the Talon brothers, reached Presidio San Juan Bautista with a variety of trade goods but the Spanish remained suspicious of his intentions and held him under house arrest to await orders from Mexico City on how to proceed. While he waited, the thirty-eight-year-old became betrothed to the teenaged Manuela Sanchez-Navarro, a granddaughter of the Spanish garrison commander, Diego Ramón. Ordered to Mexico City to explain his presence on the frontera, St. Denis convinced Spanish officials to reoccupy East Texas. Returning to the Rio Grande, he guided Ramon’s expedition back toward La Louisiane, helping found six missions and a presidio between the Neches and Red rivers. This chore finished, he returned to San Juan Bautista in 1717 and got married.
Events in Europe heightened tensions between the Spanish and French, so he returned to Natchitoches where he received orders to head to Mexico City as an envoy. Reluctantly obeying, he learned of a plot to have him imprisoned and sent to Spain. He dodged the trap and returned to La Louisiane in 1719. His wife joined him soon after under special passport.
He spent the rest of his career between Le Poste de Cadodaquoius, a trading station on the Red River in present-day Bowie County, Texas, and the village of Natchitoches. In the meantime, the Spanish missions and presidio he helped lure into East Texas became economically and socially dependent on the French trade network and fostered a robust contraband trade. St. Denis died in 1744, just shy of his seventieth birthday.
