Rosecrans had not been mistaken in Bragg's intention. About nine o'clock the next morning at Crawfish Spring, where the general headquarters were, we heard firing on our left, and reports at once came in that the battle had begun there, Bragg being in command of the enemy. Thomas had barely headed the Confederates off from Chattanooga. We remained at Crawfish Springs on this day until after one o'clock, waiting for the full proportions of the conflict to develop. When it became evident that the battle was being fought entirely on our left, Rosecrans removed his headquarters nearer to the scene, taking a little house near Lee and Gordon's Mills, known as the Widow Glenn's. Although closer to the battle, we could see no more of it here than at Crawfish Springs, the conflict being fought altogether in a thick forest, and being invisible to outsiders. The nature of the firing and the reports from the commanders alone enabled us to follow its progress.
That we were able to keep as well informed as we were was due to our excellent telegraphic communications. By this time the military telegraph had been so thoroughly developed that it was one of the most useful accessories of our army, even on a battlefield. For instance, after Rosecrans had taken Crawfish Springs as his headquarters, he had given orders, on September 17th, to connect the place with Chattanooga, thirteen miles to the northwest. The line was completed after the battle began on the 19th, and we were in communication not only with Chattanooga, but with Granger at Rossville and with Thomas at his headquarters. When Rosecrans removed to the Widow Glenn's, the telegraphers went along, and in an hour had connections made and an instrument clicking away in Mrs. Glenn's house. We thus had constant information of the way the battle was going, not only from the orderlies, but also from the wires.
This excellent arrangement enabled me also to keep the Government at Washington informed of the progress of the battle. I sent eleven dispatches that day to Mr. Stanton. They were very brief, but they reported all that I, near as I was to the scene, knew of the battle of September 19th at Chickamauga.
It was not till after dark that firing ceased and final reports began to come in. From these we found that the enemy had been defeated in his attempt to turn and crush our left flank and secure possession of the Chattanooga roads, but that he was not wholly defeated, for he still held his ground in several places, and was preparing, it was believed, to renew the battle the next day.
That evening Rosecrans decided that if Bragg did not retreat he would renew the fight at daylight, and a council of war was held at our headquarters at the Widow Glenn's, to which all the corps and division commanders were summoned. There must have been ten or twelve general officers there. Rosecrans began by asking each of the corps commanders for a report of the condition of his troops and of the position they occupied; also for his opinion of what was to be done. Each proposition was discussed by the entire council as it was made. General Thomas was so tired—he had not slept at all the night before, and he had been in battle all day—that he went to sleep every minute. Every time Rosecrans spoke to him he would straighten up and answer, but he always said the same thing, "I would strengthen the left," and then he would be asleep, sitting up in his chair. General Rosecrans, to the proposition to strengthen the left, made always the same reply, "Where are we going to take it from?"
After the discussion was ended, Rosecrans gave his orders for the disposition of the troops on the following day. Thomas's corps was to remain on the left with his line somewhat drawn in, but substantially as he was at the close of the day. McCook was to close on Thomas and cover the position at Widow Glenn's, and Crittenden was to have two divisions in reserve near the junction of McCook's and Thomas's lines, to be able to succor either. These orders were written for each corps commander. They were also read in the presence of all, and the plans fully explained. Finally, after everything had been said, hot coffee was brought in, and then McCook was called upon to sing the Hebrew Maiden. McCook sang the song, and then the council broke up and the generals went away.
This was about midnight, and, as I was very tired, I lay down on the floor to sleep, beside Captain Horace Porter, who was at that time Rosecrans's chief of ordnance. There were cracks in the floor of the Widow Glenn's house, and the wind blew up under us. We would go to sleep, and then the wind would come up so cold through the cracks that it would wake us up, and we would turn over together to keep warm.
At daybreak we at headquarters were all up and on our horses ready to go with the commanding general to inspect our lines. We rode past McCook, Crittenden, and Thomas to the extreme left, Rosecrans giving as he went the orders he thought necessary to strengthen the several positions. The general intention of these orders was to close up on the left, where it was evident the attack would begin. We then rode back to the extreme right, Rosecrans stopping at each point to see if his orders had been obeyed. In several cases they had not been obeyed, and he made them more peremptory. When we found that McCook's line had been elongated so that it was a mere thread, Rosecrans was very angry, and sent for the general, rebuking him severely, although, as a matter of fact, General McCook's position had been taken under the written orders of the commander in chief, given the night before.
About half past eight or nine o'clock the battle began on the left, where Thomas was. At that time Rosecrans, with whom I always remained, was on the right, directing the movements of the troops there. Just after the cannon began I remember that a ten-pound shell came crashing through our staff, but hurting nobody. I had not slept much for two nights, and, as it was warm, I dismounted about noon and, giving my horse to my orderly, lay down on the grass and went to sleep. I was awakened by the most infernal noise I ever heard. Never in any battle I had witnessed was there such a discharge of cannon and musketry. I sat up on the grass, and the first thing I saw was General Rosecrans crossing himself—he was a very devout Catholic. "Hello!" I said to myself, "if the general is crossing himself, we are in a desperate situation."
I was on my horse in a moment. I had no sooner collected my thoughts and looked around toward the front, where all this din came from, than I saw our lines break and melt away like leaves before the wind. Then the headquarters around me disappeared. The gray-backs came through with a rush, and soon the musket balls and the cannon shot began to reach the place where we stood. The whole right of the army had apparently been routed. My orderly stuck to me like a veteran, and we drew back for greater safety into the woods a little way. There I came upon General Porter—Captain Porter he was then—and Captain Drouillard, an aide-de-camp infantry officer attached to General Rosecrans's staff, halting fugitives. They would halt a few of them, get them into some sort of a line, and make a beginning of order among them, and then there would come a few rounds of cannon shot through the tree-tops over their heads and the men would break and run. I saw Porter and Drouillard plant themselves in front of a body of these stampeding men and command them to halt. One man charged with his bayonet, menacing Porter; but Porter held his ground, and the man gave in. That was the only case of real mutiny that I ever saw in the army, and that was under such circumstances that the man was excusable. The cause of all this disaster was the charge of the Confederates through the hiatus in the line caused by the withdrawal of Wood's division, under a misapprehension of orders, before its place could be filled.
