Career
He is most notable for the influence he had on the work of his great-grandson, author William Faulkner. Although born in Knox County, Tennessee, Falkner lived with his family in Ste. Genevieve, Missouri and Pontotoc, Mississippi before settling at the age of 17 in Ripley, Tippah County, Mississippi.
He served in the Mexican-American War and, when the American Civil War broke out, he raised a company of men and was made colonel in the Second Mississippi Infantry of the Confederate Army.
Later, he was demoted in an election of officers. He subsequently formed a unit known as the 1st Mississippi Partisan Rangers.
He never regained a prominent role in the Confederate Army, but he was forever known as "Colonel Falkner" or just "The Old Colonel" after the war. During Reconstruction, he was active in rebuilding northern Mississippi and founded the Ship Island, Ripley, and Kentucky Railroad Company.
The first and only station on the line was located in what is now the community of Falkner.
He died the next day. As a child, Falkner"s great-grandson William Faulkner is reported to have said, "I want to be a writer like my great-granddaddy." Whether or not young William actually said this, the elder Falkner served as the model for the character of Colonel John Sartoris, who appeared in the novels Sartoris (1929) (reissued in an expanded edition as Flags in the Dust (1973)) and The Unvanquished (1938) as well as a number of short stories. Thus, Colonel Falkner is the inspiration for an integral part of the history of Faulkner"s fictional Yoknapatawpha County.
