One more question! Thanks so much for your help.
On page 73 the rules for Retiring Units say: "A retire move is a normal move in every respect but must be made entirely within the confines of the unit's rear (or opposing) quarter ....... A unit that is unable to retire as required will break instead. Remove the unit as if it had been destroyed. This can happen because enemy units or impassable terrain block its rearward movement."
But the movement rules are very forgiving in Black Powder. Therefore if, for example, enemy cavalry are sitting in a block in the middle of my rear quarter could I just say my unit retreats backward around them?
How about if they are just two or three inches away from my rear, but not wide enough to cover the span of my fear quarter. Can I still argue that my retreating troops just snake around them, around the edges (as long as I'm not in a very chunky formation)?
I appreciate that "fair play" might be the best guide here. But it seems very open to interpretation. It would be much easier to decide if the rule instead said that retreating troops retire directly backwards, not just into the rear (or opposing) arc.
Thanks for any views!
Mike
