Yeah that's the one where he leads you up into a village so he can ransack some hut looking for evidence(?) while you fend off a heavy attack.
The fort I attacked is the one nearest the other side which is (for now) verboten. I could have avoided the mine fields completely by following a path to the right that leads up a hill overlooking the backside of the fort (the one part, you'd think, that would be most heavily defended, except it's totally undefended). AFAICT, the main doors to the fort never open, and there's no other way in, unless it's through some cave somewhere.
From there you can just drop in behind a big building and climb a ladder to the roof. The bad news is, once you're spotted, or even if you're not, they can climb the roof too. Bait, and the lions, tigers and bears it brings are your friend.
For my next foray, I'm taking the suppressed sniper rifle and try to get the two main snipers up top before going in, even though they were mostly not a problem -- I killed one with an arrow after he wandered down the stairs inside the fort, and the other had an unfortunate encounter with a jaguar. I'll leave the RPG home, and pray I won't need it.
