Great update! The point of revisionism and counter-revisionism was a pretty funny one to see. I remember reading some McClellan apologism in the 1920s-30s from some anti-Radical Republican historians. The historiography of this war would be an interesting one:
- McDowell would be a martyr for the Union and since everyone in the pre-war officer corps liked him (including Grant and Sherman), they'd probably have everything good to say about him in their memoirs. Funnily enough, I actually imagine that he's treat like a Lyons figure from OTL, great potential but cut short, which would be subject to revision and counterrevisionism over whether Baltimore and Second Maryland were actually competently handled.
- Hooker would probably be largely the same as OTL. Someone who helped build up the Eastern Army's army but dropped the ball.
- Doubleday is a matter of: is he good or just lucky? Napoleon would of course say the latter is better, but Doubleday's critics (Meade, conservative officers and politicians) would probably argue that Doubleday was lucky in getting "glorious" assignments at Washington and Union Mills and that the more ugly and inconclusive slugfests at Mine Run and North Anna were proof of his mediocrity.
Cheatham is widely considered the second best division commander in the Army of Tennessee, second only to Cleburne. He was a hard fighter and his career as corps commander was controversial. While he did have initiative in his first battle that only failed due to a lack of coordination on Hood's end (Atlanta, July 22), Hood's Tennessee adventure didn't offer many opportunities to distinguish any Confederate generals. There was the Spring Hill fiasco where Cheatham failed to block the critical road used by Schofield to escape an encirclement, but there was plenty of blame to go around. A more unforgivable event was Stone River, where Cheatham was allegedly drunk and got his division butchered in an attack.And with the removal of Johnston, I wonder how much better Cheatham will do? I know very little of this figure, but somehow feel that he will do worse, though perhaps not as badly as Hood in OTL when he fought Sherman.
