20. Orders have been issued, and to-morrow a great battle will be fought. May God be with our army and favor us with a substantial victory! My brigade will move at daylight. It is now getting ready.
22. The day is delightful. Lookout and Moccasin are furious. The Eleventh Corps (Howard's) is now crossing the pontoon bridge, just below and before us, to take position for to-morrow's engagement. Sherman is also moving up the river on the north side, with a view to getting at the enemy's right flank. My brigade will be under arms at daylight, and ready to move. Our division will operate with Sherman on the left. Hitherto I have gone into battle almost without knowing it; now we are about to bring on a terrible conflict, and have abundant time for reflection. I can not affirm that the prospect has a tendency to elevate one's spirits. There are men, doubtless, who enjoy having their legs sawed off, their heads trepanned, and their ribs reset, but I am not one of them. I am disposed to think of home and family--of the great suffering which results from engagements between immense armies. Somebody--Wellington, I guess--said there was nothing worse than a great victory except a great defeat.
Rode with Colonel Mitchell four miles up the river to General Davis' quarters; met there General Morgan, commanding First Brigade of our division; Colonel Dan McCook, commanding Third Brigade, and Mr. Dana, Assistant Secretary of War.
23. It is now half-past five o'clock in the morning. The moon has gone down, and it is that darkest hour which is said to precede the dawn. My troops have been up since three o'clock busily engaged making preparation for the day's work. Judging from the almost continuous whistling of the cars off beyond Mission Ridge, the rebels have an intimation of the attack to be made, and are busy either bringing reinforcements or preparing to evacuate.
Noon. There has been a hitch in affairs, and I am still in my tent at the old place.
About 2 P. M. a division or more was sent out to reconnoiter the enemy's front. The movement resulted in a sharp fight, which lasted until after sunset. Both artillery and infantry were engaged. As night grew on we could see the flash of the enemy's guns all along the crest of Mission Ridge, and then hear the report, and the prolonged reverberations as the sound went crashing among ridges, hills, and mountains. Rumor says that our troops captured five hundred prisoners.
