Double Bonus?

[GrudgeBringer]

I just won my first game (on normal ect ect) but at least I feel like I can do most (not all)stuff now.

Seems if as CSA if you take Alexandria and put 'Ol'Stonewall" there with a GOOD Corps they can't phase him much less MOVE him.

Then the AI for some stupid reason will head for Harpers Ferry (where I have my second Corps) eventually and Washington is left fairly open....Game over at turn 33.

I feel like I'm cheating, and think I will have to impose some 'House Rules' about taking Washington before a certain turn.

But to my Question....IF you put 1 Artillerest with a Corp everyone gets 20% bonus on Art.

If you put another Artillerest as a Division commander will the whole Corps get a Double Bonus of 40%?

Will the Division only get 40%?

You can't stack Bonus like that and it stays at 20%?

Any info would be appreciated.....THANKS Guys

no stacking.
its 20% even with 50 artillerists.

I believe this is true for the 'cavalry' ability too. Maybe all of them.
So in general, the effects of abities like these are not cumulative.
Can anyone verify?
