Hon. C. A. Dana, Chattanooga.

Your dispatches of yesterday are received. I am rejoiced that you have got safely back. My anxiety about you for several days had been very great. Make your arrangements to remain in the field during the winter. Continue your reports as frequently as possible, always noting the hour.

Colonel Wilson and I reached Chattanooga on November 17th. As soon as I arrived I went to Grant's and Thomas's headquarters to find out the news. There was the greatest hopefulness everywhere. Sherman, they told me, had reached Bridgeport, and a plan for attacking Bragg's position was complete and its execution begun by moving a division of Sherman's army from Bridgeport to Trenton, where it ought to arrive that day, threatening the enemy by Stevens's Gap. The remainder of that army was to move into Lookout Valley by way of Whiteside, extending its lines up the valley toward Trenton, as if to repeat the flanking movement of Rosecrans when he followed Bragg across the Tennessee. Having drawn the enemy's attention to that quarter, Sherman was to disappear on the night of the 18th and encamp his forces behind the ridge of hills north of the Tennessee, opposite to Chattanooga, and keep them there out of sight of the enemy during the 19th. That same night a bridge was to be thrown across the river just below the mouth of Chickamauga Creek, so that on Saturday morning, November 20th, Sherman's command would be across before daylight, if possible. As soon as over he was to push for the head of Missionary Ridge, and there engage the enemy.

At the same time that Sherman's wing advanced, Granger, with about eighteen thousand men, was to move up on the left of the Chattanooga lines and engage the Confederate right with all possible vigor. Hooker, who had been in the Lookout Valley ever since he joined the army in November, was to attack the head of Lookout Mountain simultaneously with Sherman's attack at the head of Missionary Ridge, and, if practicable, to carry the mountain.

It is almost never possible to execute a campaign as laid out, especially when it requires so many concerted movements as this one. Thus, instead of all of Sherman's army crossing the Tennessee on the night of the 18th, and getting out of sight as expected behind the hills that night, a whole corps was left behind at daylight, and one division had to march down the valley on the morning of the 20th in full view of the enemy, who now understood, of course, that he was to be attacked. Bragg evidently did not care to risk a battle, for he tried to alarm Grant that afternoon by sending a flag over, and with it a letter, saying, "As there may still be some non-combatants in Chattanooga, I deem it proper to notify you that prudence would dictate their early withdrawal." Of course, we all knew this was a bluff.

On the morning of the 20th a heavy rain began, which lasted two days and made the roads so bad that Sherman's advance was almost stopped. His march was still further retarded by a singular blunder which had been committed in moving his forces from Bridgeport. Instead of moving all the troops and artillery first, the numerous trains which had been brought from West Tennessee were sent in front rather than in rear of each division. Grant said the blunder was his; that he should have given Sherman explicit orders to leave his wagons behind; but no one was so much astonished as Grant on learning that they had not been left, even without such orders.

Owing to these unforeseen circumstances, Sherman's rear was so far behind on the morning of the 23d, three days after Grant had planned for the attack, that it was doubtful whether he could be ready to join the movement the next day, November 24th. It was also feared that the enemy, who had seen the troops march through Lookout Valley and then disappear, might have discovered where they were concealed, and thus surmise our movements.

On account of these hitches in carrying out the operations as speedily as Grant had hoped, it was not until November 23d that the first encounter in the battle of Chattanooga occurred. It was the beginning of the most spectacular military operations I ever saw—operations extending over three days and full of the most exciting incidents.

Our army lay to the south and east of the town of Chattanooga, the river being at our back. Facing us, in a great half circle, and high above us on Lookout Mountain and Missionary Ridge, were the Confederates. Our problem was to drive them from these heights. We had got our men well together, all the re-enforcements were up, and now we were to strike.
