The Battle of Augusta was an engagement during the American Civil War that took place on September 27, 1862, in Augusta, Kentucky, between the Bracken County Home Guard (Union) and the Confederate Second Kentucky Cavalry Regiment under command of Colonel Basil W. Duke, a brother-in-law of John H. Morgan. The skirmish resulted in a victory for the Confederacy but the number of Confederate casualties and lack of ammunition for his artillery caused Colonel Duke to abandon plans to cross over the Ohio River into Ohio. A result of the fighting was that twenty buildings were set on fire and destroyed.
