Guys, for those of you who never considered it, there is a fun novel called "Stonewall Goes West" by R.E Thomas about this.
In "Stonewall Goes West," the fabled Jackson survives his wounding at Chancellorsville in 1863 to assume command of the South's Army of Tennessee. In a final bid to reverse the failing fortunes of the Confederacy, a maimed but unbowed General Jackson confronts not only Sherman's Union armies on the western front, but his own recalcitrant generals. "Stonewall Goes West" gives the classic "what if" a fresh, new answer in a fast-paced tale, rich with authentic detail, filled with battle and strategy, and populated by the Civil War's most colorful personalities.
