One thing is sure: the Confeds would have been 12/12 in having higher losses than the Union. That's not good, especially if you are, supposedly, the "defender," and even worse if you have no other strategic material advantages.
If Burnside had listened to Hancock... (I mean as long as we are doing the what-if game) Perhaps, Lee would have listened to Jackson, who wanted the line to be on the North Anna River so he could have room to manuever, which was denied him at Fredericksburg because of the Union guns on Stafford Height.
True. I’m just finishing a book on the German economy during WWII. It was maddening reading how they were trying to maximize production against a coalition they could never hope to defeat.
