This may well be ASB territory, but I wanted to have a go at it because I'm curious as to the consequences. Every battle meaning EVERY battle. Even Henry and Donelson. Every skirmish. Every everything, including Antietam and Shiloh. Albert Johnston beats Grant back over Pittsburgh Landing. Lee's orders are never lost and so he crushes McClellan. How long before Lincoln decides to stop sending soldiers into a Southern meat grinder?
