The right wing stood as follows:  General Pat Cleburn’s Division on right of Stewart, with Breckenridge’s on the extreme right of the infantry, under the command of Lieutenant General D.H.  Hill, with Cheatham’s Division of Folk’s Corps to the left and rear of Cleburn as support, with General Walker’s Corps acting as reserve.  Two divisions of Forrest’s Cavalry, one dismounted, were on the right of Breckenridge, to guard that flank, while far out to the left of Longstreet were two brigades of Wheeler’s Cavalry.  The extreme left of the army, Preston’s Division, rested on Chickamauga Creek, the right thrown well forward towards the foot hills of Mission Ridge.

In the alignment of the two wings it was found that Longstreet’s right overlapped Folk’s left, and fully one-half mile in front, so it became necessary to bend Stewart’s Division back to join to Cleburn’s left, thereby leaving space between Bushrod Johnson and Stewart for Hood to place his three brigades on the firing line.

Longstreet having no artillery, he was forced to engage all of the thirty pieces of Buckner’s.  In front of Longstreet lay a part of the Twentieth Corps, Davis’ and Sheridan’s Divisions, under Major General McCook, and part of the Twenty-first Corps, under the command of General Walker.  On our right, facing Polk, was the distinguished Union General, George H. Thomas, with four divisions of his own corps, the Fourteenth, Johnson’s Division of the Twentieth, and Van Cleve’s of the Twenty-first Corps.

General Thomas was a native Virginian, but being an officer in the United States Army at the time of the secession of his State, he preferred to remain and follow the flag of subjugation, rather than, like the most of his brother officers of Southern birth, enter into the service of his native land and battle for justice, liberty, and States Rights.  He and General Hunt, of South Carolina, who so ably commanded the artillery of General Meade at Gettysburg, were two of the most illustrious of Southern renegades.

In the center of Rosecrans’ Army were two divisions, Woods’ and Palmer’s, under Major General Crittenden, posted along the eastern slope of Mission Ridge, with orders to support either or both wings of the army, as occasions demanded.

General Gordon Granger, with three brigades of infantry and one division of cavalry, guarded the Union left and rear and the gaps leading to Chattanooga, and was to act as general reserve for the army and lay well back and to the left of Brannan’s Division that was supporting the front line of General Thomas.

The bulk of the Union cavalry, under General Mitchell, was two miles distant on our left, guarding the ford over Chickamauga at Crawfish Springs.  The enemy’s artillery, consisting of two hundred and forty-six pieces, was posted along the ridges in our front, giving exceptional positions to shell and grape an advancing column.

Bragg had only two hundred pieces, but as his battle line occupied lower ground than that of the enemy, there was little opportunity to do effective work with his cannon.
