Lieutenant Colonel William D. Lannom
When the 7th Kentucky Infantry was formed in 1861, William D. Lannom was commissioned as the Lieutenant Colonel and second in command. He fought with the regiment at Shiloh, where he took command on April 7 after Colonel Wickliffe fell. Shortly after the battle, the 7th moved to the area around Corinth, Mississippi. Lieutenant Colonel Lannom fell ill and felt he was unfit for duty. Therefore, he resigned his commission in May of 1862.
In September of 1863, he would reenter the war, being given a commission again as Lieutenant Colonel of the 12th Kentucky Cavalry and would fight with that regiment until the war's end in the same brigade as the 7th Kentucky, under General Forrest.
