If one is trying to produce ECW rules I am sure there needs to be a mechanism to produce the uncontrolled advances to which undisciplined horse were prone. I am not keen on the ideal hat simply says, Royalist cavalry did this, Parliamentarian didn't. But I think, particularly if reproducing a historical encounter, there should be a simple way of doing this. In the rules at present, units successful in melee must occupy the ground of their defeated foe, so we have a start. Perhaps the simplest thing would be that for troops prone to uncontrolled advance (identified in the scenario),if they draw a card of 5 or higher in their next activation, they must continue straight ahead and engage any enemy unit in their way. Anything lower they remain under control. Picking up on an idea posted elsewhere, victorious cavalry units MUST be the first ones activated in a command. For a second move it would be 4 or higher, and so on. That is, once you have started to pursue, it becomes increasingly difficult to stop. If pursue off the field, then normal rules for re-entry apply. Does anyone have any thoughts as to this idea? The first card number could be adjusted as a result of play testing. Troops engaged in pursuit could be identified with a suitable marker, an extra one added for each move they continue to pursue.
