 Headquarters Department of East Tennessee
Knoxville, Tenn., April 13, 1862
   On the 11th General Mitchel, with a Federal force, well ascertained to be about 8,000, with four batteries, entered Huntsville, capturing twenty-one engines and three trains of cars {on the Memphis & Charleston RR}. They came from Murfreesborough via Shelbyville and Fayetteville, and were followed by two additional regiments, making a force between 8,000 and 10,000 strong. Pushing their trains on beyond Stevenson, they destroyed the bridge over Widden's Creek, 4 miles west of Bridgeport, and secured their flank against any movement by rail from Chattanooga. I have two regiments at Bridgeport and two at Chattanooga, under the command of General Leadbetter; one of the latter, the Forty-third Georgia, is awaiting the arrival of arms from Richmond.
   General Maxey, with three regiments and a battalion, passed through Huntsville the day previous to its occupation by the enemy. The three armed regiments between Bridgeport and Chattanooga were to have completed the re-enforcements intended for General Beauregard. My own command not being large enough for offensive movements, and feeling that on the fate of the army at Corinth hung the fate of East Tennessee, I felt justified in ordering this force to General Beauregard even before being called upon by him for re-enforcements.

   General Beauregard telegraphs that six regiments from Pemberton's command are en route for Chattanooga. He suggests a movement from that point, taking the enemy in reverse at Huntsville. I could add four regiments, making a force of between 5,000 and 6,000 effective men, but the destruction of the road west from Bridgeport renders the operation of artillery on that line now impracticable. A demonstration of 5,000 infantry toward Huntsville might alarm Mitchel, but no decisive results could be reasonably anticipated. The advance of a force from Kingston by Sparta on Nashville is the strategic move, offering the greatest results and the most practicable in operation. I so telegraphed General Beauregard, notifying him of the destruction of the bridges on the Memphis road, and giving him an opportunity to countermand the order to the South Carolina regiments and to direct them to re-enforce him by [the] Montgomery and the Mobile and Ohio road.

   The Eufaula Artillery, which was ordered here with its battery, is still without guns. The pieces, with ammunition, should be sent from Richmond as soon as practicable.
   I am, sir, respectfully, your obedient servant,
E. Kirby Smith
Major-General Commanding
