Something for the weekend. Kentucky Battle Song, sung by Bobby Horton who has waged a one man crusade to bring Civil War music to modern audiences.. The Civil War in border states was often literally a war of brother against brother. Some 100,000 men of the Blue Grass State fought for the Union, while 25,000-40,000 served the Confederacy. Written in 1863, lyrics and music by Charlie L. Ward, the song celebrates the Orphan Brigade and other Kentucky Confederate units who left their homes in Union controlled Kentucky to battle for the South.
