we threw up temporary fortifications a short distance in the rear of the line which had been our reserve in the morning. We remained here until near 4 o'clock in the afternoon, not knowing that the right had given way. About this time we were heavily attacked. The line who seemed to be determined to break our lines. Our brigade was constantly cheering and encouraging the line in front of us, though we were exposed to a terrible fire of artillery and musketry. This was kept up about an hour, when an officer came up and ordered us back. We would not reiter until we heard from you. In a moment you came in person, giving the order to fall back; this we did in the best possible manner, and after getting back to the hill assisted in getting the brigade together, and, under your direction, moved back to Rossville.

On the 21st I formed my regiment on the extreme right of the brigade and threw up breastworks, where it remained until 1 o'clock next morning, when, by your order, we moved back to Chattanooga. I will not eulogize my officers and men one by one, but it is sufficient to say they are good and true. The above is as near a correct history of the part the Seventy-ninth Illinois took in the battle as I can remember. I submit it for your consideration, and have the honor to remain your obedient servant,
