Brigadier General Thomas Flournoy (1775–1857) was a prominent 19th-century American lawyer, planter, and U.S. Army officer. After studying at the prestigious Litchfield Law School, he established a highly successful legal practice and plantation in Augusta, Georgia, where he became famously known for killing a rival in an 1804 duel. Despite having no prior military experience, President James Madison commissioned him as a Brigadier General at the outbreak of the War of 1812. He ultimately assumed command of the Seventh Military District in New Orleans, overseeing operations across Louisiana, Tennessee, and the Mississippi Territory. However, his tenure was plagued by political friction, passive defensive strategies during the Creek War, and a breakdown in relations with local leaders, leading to his resignation in 1814 and subsequent replacement by Andrew Jackson. Following a brief postwar stint as a U.S. Indian commissioner, Flournoy retired to his Georgia estate, where he managed his plantation and large family until his death in 1857.
