In 1864 General McPherson assumed command of the Army of the Tennessee and for a short time no officer was appointed to command the corps. Eventually Major General Francis P. Blair, Jr. took command. Sherman transferred the rest of the corps to Georgia to take part in the Atlanta campaign. Only the 3rd and 4th Divisions took part in the campaign and these divisions missed much of the early battles but played a major role in the Battle of Kennesaw Mountain and the Battle of Atlanta. The 3rd Division under Mortimer D. Leggett had a particularly hard fight on Bald Hill. Bald Hill would be renamed Leggett's Hill in honor of the division commander. After the fall of Atlanta, General Blair took a leave of absence from the army and General Thomas E. G. Ransom commanded the XVII Corps. When Ransom died of exposure during the pursuit of John Bell Hood's army Blair returned shortly after to command of the corps.
