Dec 27, 1861 Wrote Brig. Gen. Don Carlos Buell, commander of the Army of the Ohio, “I enclose herewith an order defining the limits of my command. The object is that you may know its extent, and to express to you a desire to cooperate with you as far as practicable, especially in suppressing the smuggling that is now being carried on along the Ohio, to some extent, with the enemy.
I would respectfully request a Copy of such orders as you may have published on the subject.”
