I can start on a Warve map for this mod. It's a battle I was always thinking about doing. Also, I probably could answer any questions you have regarding the Brunswick faction. They were always a favorite army of mine as they all looked like they were going to an enormous funeral.
Brunswick Army List would look as follows:
Lieb Battalion
Avantgard (2 co Jagers, 2 co Light Infantry)
Line Battalions (1st, 2nd, 3rd)
Light Battalions (1st, 2nd, 3rd)
Hussar regiment
Uhlan squadron
Horse Arty Battery
Foot Arty Battery
Faction Leader- The Duke of Brunswick
