I had a great game of Cossacks vs Swedes using FK&P with the "eastern front" variations from the Tales from the Wargaming Shed blog.
This would be an interesting clash, as the two armies were very different: essentially a western pike & shot army (the Swedes) against an eastern pike & shot army (the Cossacks). Indeed, so different were the Cossacks that Bevan, my opponent, asked if he could use the Swedes despite the dice initially saying otherwise as he wasn’t sure how to fight with the Cossacks.
In short, the game was epic: click on the link below to see all...
