During the crossing of Sand Mountain and Lookout Mountain, in September 1863, General David S. Stanley fell ill. On the 18th, he "went to the rear," leaving General Mitchell in (temporary) command (see source). He continued to be ailing for the next two months, and finally asked to be relieved from duty to recruit his health. This source (presented via Perseus Digital Library) is from an extract of Civil War field notes, as published in The Dispatch on September 16, 1863.

General Stanley is relieved of command, replaced by (permanent replacement) Washington Lafayette Elliott, Nov. 1863:
On November, 16 1863, Stanley was relieved of command and replaced by Washington LaFayette Elliott (W.R. Carter, History of the First Tennessee Volunteers). Dennis W. Belcher, in The Cavalry of the Army of the Cumberland (Jefferson: McFarland, 2016) cites the date as November 12, 1863; see pg. 175. William Randolph Carter, author of History of the First Regiment of Tennessee Volunteer Cavalry, states this fact and gives an exact date. Carter, of the First Tennessee Vols, was under Stanley's command and crossed Lookout Mountain with Stanley's Corps.
16 November 1863: General D. S. Stanley (Davis S. Stanley): "relieved from duty as chief of cavalry, Army of the Cumberland, and General W. L. Elliott placed in command."

In an 1883 letter from General D.S. Stanley to Marshall P. Thatcher, author of A Hundred Battles in the West: St. Louis to Atlanta, 1861-1865, the general identifies his illness as acute dysentery, contracted ten days before the Battle of Chickamauga. That would make the date of the beginning of his illness about September 9th or 10th. The battles happened on the 19th and 20th. He recuperated at Stevenson, Alabama. (Thatcher, p.249, letter from D.S. Stanley).

Quote from this source: "Brigadier-General Elliott was, October 3, 1863, ordered to duty in the Department of the Cumberland..." (Date given here is later than dates above and may refer to a different event; the date is before the date he relieved Stanley, and is when he was first transferred to the Dept. of the Cumberland, if the date is accurate--it is being mentioned two years later in this recommendation for promotion).

ROBERT B. MITCHELL ASKS TO BE RELIEVED OF COMMAND, OCT. 1863
About a month after Robert B. Mitchell takes (temporary) command of cavalry, he, too, asks to be relieved for reasons of health, citing the exacting conditions of the command itself.
