After a few turns, the Union is threatening Winchester VA. I chose to move Johnstons army up North to grow stronger in Winchester and hold off Union incursions. Johnstons army was not at full strength, let's say average 80% with some brigades at 75% - but most at full strength.
Battle resolution = a division scaled unit is battling wiht Johnstons force - he loses 6 brigades during the battle - oh help! A second battle occurs during this battle resolution - a second Union division seems to have joined the dance - total mayhem - and Johnston loses the remainder of his army of Shenandoah. All brigades destroyed !!!
So an entire army (or corps in reality) destroyed in one "early" game turn.
This can't be true ! Isn't there any way to tone down this massive brigade destruction ?
I had changed the chance to hit from 150 to 125 before I had this battle (but I started this campaign at 150 and later had it reduced to 125 before this battle).
- so I think this crazy battle happened with a 125 chance to hit. I still find this to be the only real game breaker in this game !

even if the setting is 150, there's really no justification that a corps is totally destroyed in an open field battle by another corps.
