B.O. Holman attended the University of Virginia from 1850 to 1852. After leaving, he studied law in Tennessee and practiced in Alabama. When the war broke out he enlisted in the 13th Regiment Alabama Volunteers. Holman was captured at Gettysburg, probably when Michigan's "Iron Brigade" overran McPherson's Woods on July 1, 1863. He was incarcerated at Ft. Delaware where he contracted smallpox and died January 1864.
Holman's University of Virginia autograph album was signed by future Confederate Brigadier General Lucius E. Polk. Wounded four times in the war, Polk returned to his home in Columbia, Tennessee, on crutches. There, despite his handicap, he successfully defied and routed a group of Klansman attempting to whip a local field hand. Later he served as a delegate to the Democratic Convention of 1884 and was elected to the Tennessee Senate in 1887.
