I am playing BtS version 3.17 (both patches). I was attacked by a large enemy stack of horse archers, swordsmen, chariots, catapults and trebuchets. I attacked the stack with knights. All of my knights won their battles, all of them had movement left to move away, but I inflicted no flanking damage on the enemy.
Is this a glitch, or is there something in the rules that I am missing?
