The first post in my French and Indian War I wanted to show of my rather small force of British forces.
I intended to use the Black Powder rules. By switching all the ranges from inches to cm I found out that it worked rather nicely in 15mm.
The basing size I have used is one 4cm base of 4men is a tiny unit, 2 bases a small, 3 for a standard and so on. For skirmish formations I have based the miniatures 2 on a 4cm base and used double the amount of bases compare to a line formation, that means the same amount of miniature.
My tiny British force is now up to a officer, 2 standard size line formations, and small and a tiny skirmish formation.
