TULLAHOMA, August 3, 1862.

General D. C. BUELL:

Arrived here after a march of thirty-six hours from Murfreesborough. Enemy are 13 miles hence, with two roads to retreat on, one directly across the mountain, the other on Sparta. That to Sparta is by this time blocked up by General Johnson. The railroad wants but two days labor to put in complete order.

I march to-morrow in pursuit and will not stop till I drive the enemy across the mountain. I marched by way of Woodbury; Johnson by way of Liberty.

NELSON,

Major-General.

General NELSON:

It is said that Bragg crossed the river at Chattanooga about the 30th with a large force. He has certainly been repairing the Anderson road. He may design to march against Battle Creek and Decherd or in less
