I've been focusing on playing the Union in the 1862: Struggle for the Heartland as my beginning campaign game. The west essentially starts similarly as the Shiloh scenario which means I've got around half of the campaign's command issues and initial opening strategy already figured out.

Now what to do about that mess that is McClellen and the Army of the Potomac? The best I can get the command penalties down to are:
2 Corp at 0% CP.
3 Corp at 5% CP
1 Corp (that's Franklin's who doesn't start with any supporting divisional generals) at 25%.
I accomplished this by essentially breaking down a division in most of the corps and attaching as many of its units as possible to the remaining divisions in the Corp--leaving its former general unattached to supply extra command points (and bring me coffee doughnuts).
I think I ended up with 2 unused brigades and a couple of divisional HQ's which I sent to the spare artillery detachment to await further generals looking for a command a few turns down the road.
I'd be thankful to hear if anyone has done better with getting the CP's under control with the Army of the Potomac at the start of this campaign!
Best
