River defense

[lightbrave]

Thinking about a post i did a while back about spliting up coastal artillary in the southern forts, I thought of another idea based on a situation im in at the moment. I have a Corps sitting on the west side of the Mississippi river just below Cairo. I moved some ships down towards Nashville (im playing Union this time) so i anticipated the southern river fleet to come and engage and i was sure that they were down south of the mississippi. Since I was in no real threat to be attacked I split my Corps into 3 divisions to bombard the fleet as it went by. Would it be better for 3 divisions to separately engage (if they can) than all 3 at once (as a Corps)? Maybe this has already been addressed but haven't seen it in the forums. What are your thoughts guys?

You would have more chances to do less damages and receive more

Although there is a cap on how much damages you can deal or take, but still (and no, I don't remember the cap)
