In the wake of the Union victories at Corinth and Memphis, Lincoln gave Halleck command of the entire states of Kentucky and Tennessee.
WASHINGTON, June 8, 1862.
Major-General HALLECK, Corinth, Miss.:
We are changing one of the departmental lines, so as to give you all of Kentucky and Tennessee. In your movement upon Chattanooga I think it probable that you include some combination of the force near Cumberland Gap under General Morgan. Do you?
