Well it sounds like you can muster a small army. Woods craft and hunting skills will help you a lot. See but don’t be seen and all that…
Well I’m no expert but this is not rocket science. Switch rolls and think about how to attack your place. Then solve your attacks. Night or day, one, two or three points of attack. Distractions and feints, fakery. Fire bombs. I’l be backers.
As I write this I think you could use hedge rows of green brier and wild rose to steer traffic to fire zones. Stuff with big nasty thorns. Labyrinths are the in thing anyway.
