Achilles -
Thanks for the input. Unfortunately I think you may over-estimate the game engine. It can't be a perfect representation of CW warfare, but obviously it can continue to evolve into a better simulation as it continues to be tweaked. Obviously guns can be deployed as you have described - I have done it myself in MP games. However, the damage inflicted by guns unsupported by infantry at 200 yards nor the "fear" they created on the battlefield is currently simulated in the game.
In game, if you have a four-gun battery at 200 yards facing infantry, the max casualties you can inflict is anywhere from 80-200 depending on the situation (open field, hills, forest, etc) before the guns will be over-run by infantry. Opposing players can quickly switch their units into column, double time right in front of the guns, deploy into line and charge often after the guns fire 1 round and before they can fire another or limber/move. The limber/unlimber times are much much slower in game than IRL and that impacts this type of strategy as well. Simply put, rolling guns up out in the open, unsupported by infantry, in game will get those guns taken very quickly.
At Fredricksburg, Pelham held up the Union attack on the left with 2 guns. The example of Forrest at Brice's Crossroads is a good example as well as 11th Ohio Battery at the Battle of Iuka. HOWEVER, the game engine doesn't simulate these types of events. Because infantry can be TC'd and ordered - while under fire - to deploy from line into column, double time up to the guns, re-deploy into line, charge without a morale loss/check, artillery is basically a sitting duck providing none of the benefits you have ascribed in game. Perhaps IF the deployment into/out of formations were more realistic, damage/morale/fatigue hits to charging columns more accurately depicted, limber/unlimber speeds improved, what you are describing could be possible.
Finally, everyone agrees that the majority of casuaulties are going to be caused by artillery 200 yards and in. However the casualty/fatigue/morale malus currently inflicted by guns at greater than 200 yards makes them somewhat useless. I have seen players move their guns out in the open and I can't hit them with my arty at 350 yards after 15 minutes of fire. I have seen 12 pd guns inflict ZERO casualties of massed infantry at 250 yards after 10 minutes of fire from an enfilade position. And these are not isolated incidents - this is the norm.
