Pausing but a short while, we passed on, the road filled with broken wagons and abandoned caissons, till night.  Just as the head of the column emerged from a dark, miry swamp, we encountered the rear-guard of the retreating enemy.  The fight was sharp, but the night closed in so dark that we could not move.  General Grant came up to us there.  At daylight we resumed the march, and at Graysville, where a good bridge spanned the Chickamauga, we found the corps of General Palmer on the south bank, who informed us that General Hooker was on a road still farther south, and we could hear his guns near Ringgold.

As the roads were filled with all the troops they could possibly accommodate, I turned to the east, to fulfill another part of the general plan, viz., to break up all communication between Bragg and Longstreet.

We had all sorts of rumors as to the latter, but it was manifest that we should interpose a proper force between these two armies.  I therefore directed General Howard to move to Parker’s Gap, and thence send rapidly a competent force to Red Clay, or the Council-Ground, there to destroy a large section of the railroad which connects Dalton and Cleveland.  This work was most successfully and fully accomplished that day.  The division of General Jeff.  C. Davis was moved close up to Ringgold, to assist General Hooker if needed, and the Fifteenth Corps was held at Grayeville, for any thing that might turn up.  About noon I had a message from General Hooker, saying he had had a pretty hard fight at the mountain-pass just beyond Ringgold, and he wanted me to come forward to turn the position.  He was not aware at the time that Howard, by moving through Parker’s Gap toward Red Clay, had already turned it.  So I rode forward to Ringgold in person, and found the enemy had already fallen back to Tunnel Hill.  He was already out of the valley of the Chickamauga, and on ground whence the waters flow to the Coosa.  He was out of Tennessee.

I found General Grant at Ringgold, and, after some explanations as to breaking up the railroad from Ringgold back to the State line, as soon as some cars loaded with wounded men could be pushed back to Chickamauga depot, I was ordered to move slowly and leisurely back to Chattanooga.

On the following day the Fifteenth Corps destroyed absolutely and effectually the railroad from a point half-way between Ringgold and Graysville, back to the State line; and General Grant, coming to Graysville, consented that, instead of returning direct to Chattanooga, I might send back all my artillery-wagons and impediments, and make a circuit by the north as far as the Hiawasaee River.

Accordingly, on the morning of November 29th, General Howard moved from Parker’s Gap to Cleveland, General Davis by way of McDaniel’s Gap, and General Blair with two divisions of the Fifteenth Corps by way of Julien’s Gap, all meeting at Cleveland that night.  Here another good break was made in the Dalton & Cleveland road.  On the 30th the army moved to Charleston, General Howard approaching so rapidly that the enemy evacuated with haste, leaving the bridge but partially damaged, and five car-loads of flour and provisions on the north bank of the Hiawassee.
