During Lt. Gen. James Longstreet 's Knoxville Campaign that winter against Union-held Knoxville, Tennessee, Leadbetter was sent by army commander Gen. Braxton Bragg to aid the Confederate planning against the Federal positions. Leadbetter arrived on November 25 and consulted with Longstreet, using his prior knowledge of the fortifications in Knoxville he had designed the year before.
