I hope you will close down upon our left as soon as possible, and at once throw cavalry in that direction to cover our flank. I have much evidence to show that Johnston is re-enforcing Bragg with a considerable force.

If you come this way you can draw supplies from here or McMinnville. Let me hear from you frequently.

Colonel FOSTER:

You will, in order to avoid all risk of surprise on your return, employ reliable citizens at all stations and other points on the road to scout the country in their vicinity, and make arrangements with them to give you notice before running into any place of danger.

Also use the citizens in moving up the road, if necessary, taking them with you. In case only of absolute necessity, you can leave the cars and take care of your party on foot. At some of the more important points you can leave some of your own men to gain information.

In case you are compelled to leave the cars, return on the track and obstruct it in the direction of this place.

It is presumed you will take all necessary precaution of you own
