Command Post Games has just come out with a Pub Battles Battalion scale Waterloo scenario. It is primarily intended as a Kriegspiel tool, and gives a link to Too Fat Lardies copy of the Kriegspiel rules.
It does include Pub Battles battalion scale rules, and you can order a paper map to use for playing on. it is a different, closer scale, map of just the area where the battle was fought. The regular Pub Battles map won’t have the details that are desired at battalion scale.
I enjoy the current Pub Battles scale, and am not interested in battalion scale or Kriegspiel, but if that’s your thing, go for it!
