On the Antietam Campaign
At South Mountain, MGen Burnside was in command of the "Wing" of the Army of the Potomac consisting of the I Corps (MGen Hooker) and the IX Corps (MGen Reno). When General Reno was killed on September 14th, BGen Cox, of the Kanawha Division, was placed in command of the IX Corps.
At Antietam the two corps of the Wing were widely seperated, and Gen Hooker's I Corps was removed from Gen Burnside's control. Under those circumstances, though it was still nominally under Gen Cox, the IX Corps was effectively commanded by Gen Burnside.
