We had a great Napoleonic game at the Newbury Historical Study Association with about 5-6 players per side. We used Dave’s General d’Armee 2 rules which are now cemented as our rules of choice.
Personally, it was a pleasure to play against Dom from the “Boots on the Table” YouTube channel – who was a lovely guy and a skilful commander (especially given his lack of familiarity with the rules).
He made a YouTube video of the game – which you can find HERE
