I'm kind of baffled by the comments of oh, those poor besieged soldiers. Really? Her kingdom was invaded and she and her people became refugees in the wilderness unwanted by any other country. She's fighting back. And for those that are saying, well, yes, but Kosuke taught her and her officers this and that, they know better--he doesn't rule them, Sylphy does. She can take his advice or leave it. If he were by her side (which is a stupid idea for a number of reasons), he might be able to pressure her into doing things his way, but he isn't. Besides, the other side has no clue about these rules of war. I see Sylphy as adapting what she thinks will work on the battlefield and leaving the rest by the wayside as good if only the other side would fight war by the same rules. She's been through a war, Kosuke hasn't.
