Lunsford Lindsay Lomax (November 4, 1835 – May 28, 1913) was an officer in the United States Army who resigned his commission to join the Confederate Army at the outbreak of the American Civil War. He had maintained a close friendship with his West Point classmate Fitzhugh Lee, and served under him as a brigadier in the Overland Campaign. He was then given command of the Valley District, where he supervised intelligence-gathering operations by Mosby’s Rangers.
