That's true, but do not confuse Kentucky with command of the Western theatre. After being relieved in Kentucky, Sherman went on to command just a division at Shiloh, not a corps or an army, in 1862. Further, the game starts in July 1861, when Sherman was in fact in command of a brigade in Virginia/Maryland.
Edit - Historically, Sherman didn't command an army in the field until late in 1863, when Grant left him in charge of the Army of the Tennessee. His time in Kentucky was mainly a desk job, as I understand it primarily concerned with the immediate defense of Louisville, and the organizing of new forces within the state. The completed forces were eventually organized into the Army of the Ohio, under Buell. While Sherman and Buell were brigadiers of equal seniority in late 1861, by March of 1862 Buell was promoted to Major General of Volunteers, while Sherman was sent on leave, and then given a lesser assignment under Grant.
