<Li> Cleburne's Division, MG Patrick R. Cleburne (brigades of BG Lucius E. Polk, BG St. John R. Liddell, BG Bushrod R. Johnson and BG Sterling A.M. Wood). </Li> <Li> McCown's Division, MG John P. McCown (brigades of BG Mathew D. Ector, BG James E. Rains, BG Evander McNair and BG Sterling A.M. Wood). </Li> <P> The Cavalry Corps, (BG Joseph Wheeler), consisted of brigades under BG Joseph Wheeler, BG Abraham Buford, BG John Pegram and BG John A. Wharton . </P> <P> At dawn on December 31, about 6 a.m., Confederate William J. Hardee struck first, attacking the Union's right flank with the division of Maj. Gen. John P. McCown, before many in Union Brig. Gen. Richard W. Johnson's division had finished their breakfast . This was the third major battle, after Fort Donelson and Shiloh, in which an early morning attack caught a Union army by surprise . The 10,000 Confederates who massed on their left attacked in one massive wave . McCook's deceptive campfires and the relative inexperience of McCown caused his division to drift away to the left, which left a gap in the front, but the gap was filled seamlessly by the division coming up from his rear, under Maj. Gen. Patrick R. Cleburne . These two divisions swept all resistance aside . Several artillery batteries were captured without having time to fire a shot . Johnson's division, on the right, suffered over 50% casualties . His neighboring Union division to the left, under Brig. Gen. Jefferson C. Davis, was able to hold only briefly . </P>
