I am amidst a stellar victory, playing as CSA:
1st phase - all VPs taken, 3,500 CSA casualties and 5,300 Union casualties
2nd phase - all VPs taken, 2,900 CSA casualties, 5,900 Union casualties
3rd phase - the VP taken, 2,600 CSA casualties, 10,000 Union casualties.
Could such casualties even be possible during the actual battle? In that battle during day 1 my ANV units completely devastated their AoP enemies with the AoP suffering almost as many losses as it did during the whole battle of Gettysburg from July 1 tp 3.
