The largest battle fought in Kentucky, Perryville, had a large number of Kentuckians on the Union side, but only a few companies of Kentucky cavalry on the Confederate side. Most of the Confederate Kentuckians were down in Mississippi with Maj. Gen. Breckinridge's Corps. He did not get along with Gen. Bragg, the Confederate commander of the invasion of Kentucky, so his force was sent down to fight at Baton Rouge.
Did anybody?
