That there you should be an editor for historical battles and campaigns, and that you should be able to make fictional ones

Is there software for such things?

Aside from regular modding I dont think so. Besides making a fictional Historical campaign is sort of an oxymoron isnt it? Like military intellegence.

Check in the Dungeon forum. There have been several historical battles done. I don't know about campaigns though.
