The Third Corps was re-constituted four more times following its abolition. First it was re-constituted when Edmund Kirby Smith's command from East Tennessee was attached to the Army of Tennessee. Kirby Smith's corps consisted of Carter Stevenson's division, the largest at 10,000 men, John McCown's division of 5,500, Henry Heth commanded a division of 4,500 men and lastly Thomas Churchill commanded a division of 6,500 men all in all 26,500. The corps never was fully engaged in any major battle, at Cumberland Gap the corps was lightly engaged. The corps would have fought at Stones River but Stevenson's division was ordered to Vicksburg, Heth and Churchill went to Knoxville which left only John McCown and his small division. This proved to be a key factor in the battle and many say if Braxton Bragg had Smith and his four divisions, he may have won decisively, not only tactically.
