Back in the seventies, with wargames not nearly as readily available as they are now, I wrote a set of rules for playing with some of my friends, using quite large(ish) battalions of about 20-25 miniatures.
Later, I adopted Warmaster for playng this era, and we started out with units of 12 models, but later reduced the battalions/cavalry regiments to eight soldiers.
I think we can easily adapt those small battalions for Black Powder, counting the shown formations as 'Attack Columns', and forming a single rank for 'Lines' (and two files for 'March Columns').
Eight models is the minimum required for forming a 'Square', so that should work fine. Of course, we can later enlarge infantry unit size by doubling the models, or even more - but we shall have to see about that.
I know Michael has a sizeable Austrian force, and I have nicely sized French army (although some of the paintjobs are WIP, as it shows in the photos).
|French Line and Light Infantry. I shall have to pull out some red and blue, at least.|
|Fench Line and Old Guard Infantry.|
Again, some units are not quite finished...
|French Dragoon Regiment, some Line Chasseurs in early (Hussar-style) uniforms,|
and a single Italian Infantry Regiment
|French Cuirassiers, the Chevaux-Légers de Berg (too many models - I painted them back in the 'big unit' days,|
and the Lanciers Hollandais of the Guard
|Some Artillery and Staff|
