I understand that if I were to lose the battle, I would not be able to retreat the defeated knight back to KL without exceeding supply limits, since that would otherwise put me at 2/2/2/2. I would think if that did occur I would have to destroy the defeated knight that went into the battle. In this case, it is not possible for me to lose the battle so it's not a concern for me but otherwise I see how that's a risk.
Thanks in advance for the help.
