I remember a Mansa AW forum game (NC maybe) where an Ottoman leader could only enter through 1 hill tile. As soon as I fortified it with a unit he didn't attack any more, just incidentally when some unit(s) wandered too close.
Have you seen that one? I used to play it on Immortal.

As you can see on the starting screen (highly cooked map), the opponents can only enter by one forested hill tile. But this did not prevent them from attacking at all. I took so many fights on that hill, that my best Samurai ended up with 280 exp points
