You can Recruit them, but to do this you have to meet more conditions than normal...
>You have to meet one of the standard 3 conditions, and in addition, you have to finish them off with a warlord leader of your own to recruit an enemy warlord leader.
Another thing to note is that you cant get most of them until post-game....
>You have to get most of them in the post-game episodes, not in the main story.
>And also, if they're not in their last city then you can't either. If it says "Retreated to xxx" at the end screen, then they weren't, you have to push them back to their last city and then try recruit them.
