Downing’s Civil War Diary.–Alexander G. Downing.

Sunday, 20th–We had dress parade this evening at 5 o’clock and important orders were read to the command. The first is, that our division is now to be known as the First Division of the Seventeenth Army Corps; second, that on a march we are to carry only nineteen pounds, and third, that we are to be ready to form a line of battle at a moment’s notice. The reason for the last is that the rebels have driven in our pickets on the right and may make a raid. News came that a battle is being fought on the Chickamauga river, to the south of Chattanooga, with heavy loss on both sides.
