Cheatham’s Division (Polk’s Corps); Longstreet’s Corps (under Maj. Gen. John B. Hood); and Buckner’s Corps. On the east side of the stream and forming the right were Maj. Gen. Patrick R. Cleburne’s Division (Hill’s Corps), preparing to cross at Tedford’s Ford; Maj. Gen. T. C. Hindman’s Division (Polk’s Corps) opposite Lee and Gordon’s Mills; and Maj. Gen. John C. Breckinridge’s Division (Hill’s Corps) forming the extreme left opposite Glass’ Mill. Maj. Gen. Joseph Wheeler’s cavalry, stationed at the upper fords of the Chickamauga, held the left flank.
