Couple questions

[Richrd]

I haven't played since the old BG Gettysburg. I decided to start a campaign as the rebels. The first scenario is brandy station. I started up the scenario and found myself wondering; 'Whats the point?' I counldn't find any instructions as to what I was supposed to accomplish. Also is there any way to combine all those artillery sections into batteries and is there a hotkey for entrenching? Thank you. Richard.
