This last weekend was the annual Battle Day run bythe Society of Ancients. The aim is to fight one historical battle with as many rules sets as possible. The objective, partly to see how different rules cope with the events of history, mainly to have an enjoyable game with like-minded people. I have posted a description and photos of the Piquet game here:
