We played a Skirmish level battle of By Fire & Sword at the club yesterday, a demo of the rules for Andreas and actually my first Skirmish battle experience (since I have been playing division battles only up to this point).
I took the time to compile information on how a Skirmish battle works in By Fire & Sword as well as a short AAR of the action between my Polish skirmish force and the Swedish detachment Andreas fielded.
You can read all about it on my blog:
