This is the proper line of advance, but will require a very large force, certainly fifty thousand men, as their railroad facilities south enable them to concentrate at Munfordsville the entire strength of the South. General McCook's command is divided into four brigades, under Generals Wood, R. W. Johnson, Rousseau, and Negley. General Thomas's line of operations is from Lexington, toward Cumberland Gap and Ford, which are occupied by a force of rebel Tennesseeans, under the command of Zollicoffer.
