[2] Louis served as a military officer until 1736, when his father asked the Governor of Louisiana, Jean-Baptiste Le Moyne de Bienville, to promote him to lieutenant and commander of Fort Vincennes, replacing François-Marie Bissot, who was killed in an Indian raid.
[4] On October 10, 1765, he surrendered Fort de Chartres to the British.
He took his regiment to Saint-Louis, Missouri, a part of French Louisiana that had been yielded to the Spanish, who were not yet in control of the full territory.

The club's previous location (1910–1959) near Normandy is now a village called Bellerive.
