I've been toying with the idea of several Confederate Timelines in the past but I never get very far. My lack of in depth knowledge in general hampers such a endeaver as well as my generally lackadaisical personallity which I have been unable to anything about despite my best efforts.
This is more a general consensus thing.
Stonewall Jackson was an Army Commander briefly in 1862 in his famous Valley Campaign and Early was Briefly an Army Commander in 1864 when he marched to the gates of Washington and then contested the Valley with Sheridan. You could argue that they were merely detached Corps from the main Army but through those campaign Early and Jackson acted independently from the main Army in Virginia so I do not see that they could be considered anything other than commanders of their own smaller armies during those time.
