Thanks for the information about the western armies McNaughton. I inadvertently fell into the "Virginia-centric" mentality. Shame on me, since I should know better.
However, I'm not entirely convinced about the East. The Peninsula Campaign was almost a full year into the war, and I do think that it says something that the Confederate army (not the ANV until just before the Seven Days) was still organized into big blobby divisions. Lee had an excellent plan of attack, but command confusion and inefficiency greatly contributed to the limited success of the operation. Yes, I'm serious. The Union won almost every battle of the Seven Days, but McClellan retreated anyway. He did so not because of the brilliantly organized, well-oiled machinery that was the ANV, but because he had already decided that he was defeated, and made it happen (who says that he couldn't set and meet goals?

).
I would not rate Longstreet and Jackson as Corps commanders until just before the campaign to suppress Pope. Ok, maybe, maybe Jackson, but definitely not Longstreet. Officially they still weren't corps commanders even during Second Manassas/Antietam, but I grant that for all intents and purposes they were commanding corps by then.
The wing arrangement during the Seven Days was an ad hoc attempt by Lee to rectify the obvious deficiency of the Army's command structure. It didn't work very well, and the Confederates paid the price for it. Is it really just because Jackson slept during most of the Seven Days that the troops under his command contributed almost nothing to the battles that was the result of this wing/corps arrangement? If it was a corps, I would rate it as a pretty lousy one.
Is it just a coincidence that the divisions of Longstreet's wing/corps couldn't seem to find the right road to march on to save their lives, and resembled more closely the Keystone Cops than a well organized corps?
On a bit of a tangent, but related to command and leadership, how can the game represent the particularly prickly pride of southern officers? Had Jackson lived longer, he would have eventually arrested every officer under his command, and I suspect not always without reason. "General Garnett, you are under arrest! General Hill, you are under arrest! General Hood, you are under arrest! Captain, you may move your division."
McNaughton, I do like your suggestions regarding the Confederate starting orders of battle. Should maybe look to see if something similar should apply to the Union as well.
