I've had a lot of games where I'm devastating an opponent after getting ahead in a long war, and they suddenly capitulate to a third-party I'd only brought in as a bribed ally a few turns earlier and who didn't seem to be getting much of their territory. A little different scenario than what I've been describing. But is that just my perception? Did that third party have to have achieved some major success points that I'm just overlooking for this to happen? Also, does the overall history of the war shape the success evaluation, so that if I took heavy losses early, but now have the initiative, I may not be viewed as all that successful? Guess in the Victoria/Wash scenario above, I may want to bribe Wash to make peace with her before she can Capitulate to him. Since they hate each other, that should also proclude her Vassaling to him before I can get her to bow to me.
