Feudal War Question

How do you win the game on this map? I thought that in order to win you had to simply control all 6 casteles (because that's what it says in the map legend) - but I've just found out, much to my chagrin, that this must not be the case because I just deployed and attacked all my troops, grabbed all 6 castles, and the game is still going on.
Do I need to control all 3 villages also? Or is it like a conventional CC game where I have to eliminate all of my opponents?
