Ambrose Burnside advanced into East Tennessee as part of a campaign to secure saltworks in southwest Virginia and control transport and communications in that region. On October 10, 1863 Brig. Gen. Samuel Carter’s Cavalry Division (XXIII Corps) engaged Confederate forces on the East Tennessee and Virginia railroad commanded by Brig. Gen. John Williams near Bull’s Gap at Blue Springs, Tennessee. Later in the day, Brig. Gen. Edward Ferrero’s 1st Division, IX Corps broke the Confederate line and advanced to the enemy’s rear before being checked.
