For timelines of Confederate cavalry commands east of the Mississippi, May through October 1862, consult Ken Hafendorfer's They Died by Twos and Tens: The Confederate Cavalry in the Kentucky Campaign of 1862.

Don't let the title mislead anyone -- the book runs close to 1,000 pages and the detailed review of operations begins in May 1862.

It's out of print, so you may need to use interlibrary loan.
