The message board offered a recently published book on Champion Hill, which has not received the same level of attention as most major battles. Perhaps you have that book.

General Buford had equal numbers of Alabama and Kentucky units in his brigade. Each regiment, whether Alabama and Kentucky, carried the same kind of battleflag and used similar shoulder arms. Each regiment, whether Alabama and Kentucky, followed his orders and went wherever he directed. I have no doubt that each regimental commander, whether Kentucky or Alabama, collected his troops and followed General Buford to camp at Jackson MS.

War Department guidelines called for separate state brigades, so after the campaign Buford's Brigade was divided accordingly. He retained command of the Kentucky contingent.
