Last night Ian and I played a game of Tercios, based on the Polish assault on the Muscovite redoubt at Lubar, 16 September 1660. The scenario is here. It was our first full game so I kept it to a manageable ten units or so a side. The rules came back easily and we referred only rarely to the reference sheet.
it was a cracker! As the Pole, Ian pinned the redoubt from the front and sent his cavalry deep around the left flank. Polish Hussars met Muscovite Dyeti Boyarskies almost behind the Muscovite lines, smashing them and following up into supporting Muscovite horse. For a time the outcome seemed uncertain but the Muscovite horse were unable to catch their breath and a persistent Polish pursuit tipped them over into rout. To crown the moment, a Polish foot regiment broke into the redoubt and with that, they won a Clear victory (one level down from decisive). The victory conditions are straightforward: the game stops when the disparity in victory points reaches a given level.
I love these rules. The core system is so elegant and effective and feels like a Pike and Shot system ought to. Frontal assaults tend to be slow going and indecisive, but once flanks are exposed or a unit becomes disordered, things can go wrong very fast. Ian did a great job of unhinging my position and rolling up my line. A great game.
