Military service
He served in the Mexican–American War as First Lieuteant of the 2nd Regiment of Mississippi Volunteers. 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.
Falkner was also an author, writing novels, poems, a travelogue, and at least one play. His most famous work was a novel entitled The White Rose of Memphis, a murder mystery set on board a steamboat of the same name. This work was popular enough to be reprinted several times through the early 20th century, selling over 160,000 copies. Partial source: Mississippi Writers and Musicians

Influence
WC Falkner's oldest child John Wesley Thompson Falkner was the father of Murry Cuthbert Falkner. Murry's oldest child was Nobel laureate author William Faulkner. As a child, William reportedly said, "I want to be a writer like my great-granddaddy." The elder Falkner served as the model for the character of Colonel John Sartoris, who appeared in the novels Sartoris and The Unvanquished 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.
