COLUMBUS,
October 12, 1861.

Colonel TERRY, Nashville:
The enemy are advancing on Bowling Green. Take all your men to that place by rail, if possible. If there are no cars, march. If Colonel Tilghman's armed Kentucky troops have not left Nashville, give them this as General Johnston's order to go at once, by rail or afoot. Assume command of any other armed troops, except city guards, at Nashville, the commanders of which you may rank, and order them to follow you. If ranked by the commanders, you exhibit this as General Johnston's order for their movement. Order transportation from Colonel Stevenson, by rail or for the march. Your letter received this morning and answered by mail.

W. W. MACKALL,
Assistant Adjutant-General.
