Halleck went to Washington as general-in-chief, Pope was transferred to Virginia, Grant, with his own Army of the Tennessee and Rosecrans's (lately Pope's) Army of the Mississippi, was entrusted with operations on the latter river, while Buell's Army of the Ohio was ordered to east Tennessee to relieve the inhabitants of that district, who, as Unionist sympathizers, were receiving harsh treatment from the Confederate and state authorities.
Buell's successor retained the positions about Nashville, whilst a new Army of the Ohio prepared to operate in east Tennessee.
Burnside and the new Army of the Ohio had now cleared east Tennessee and occupied Knoxville (September 2), and meanwhile Rosecrans by a brilliant movement, in which he displayed no less daring in execution than skill in planning, once more manoeuvred Bragg out of his position and occupied Chattanooga.
This latter route began at Inglis's Ferry, on the New river, in what is now West Virginia, and proceeded west by south to the Cumberland Gap. The " Wilderness Road," as marked by Daniel Boone in 1775, was a mere trail, running from the Watauga settlement in east Tennessee to the Cumberland Gap, and thence by way of what are now Crab Orchard, Danville and Bardstown, to the Falls of the Ohio, and was passable only for men and horses until 1795, when the state made it a wagon road.
In East Tennessee most of the people were small farmers, while West Tennessee was a land of great slave plantations.
