General S. COOPER:
Our advance last night was at Tunnel Hill, the enemy just this side of Ringgold. We hope to maintain this position. Our inferiority in numbers, heavy loss in artillery, small-arms, organization, and morale, renders an earlier halt impossible; and should the enemy press on promptly we may have to cross Oostenaula. I have tried to communicate with Longstreet; by prompt movement he can be saved. Burnside’s force is far inferior to him. If necessary, he can go on and join Jones forces. Communication may be opened with him by the East Tennessee route. My first estimate of our disaster was not too large, and time only can restore order and morale. All possible aid should be pushed on to Resaca, and I deem it due to the cause and to myself to ask for relief from command and an investigation into the causes of the defeat.
