The Battle for Wesnoth Forums

Now I am stuck with Villagers in tumult: I killed all the enemies and occupied all villages, except the ones already occupied by the allies and I don't know what to do next. Is there a hidden village, or bandit? If so, where?

Eureka!
I found the answer:

there is a small hidden island in the middle chasm, the Troll key opens a gate, and on the island you can find another key and a chest of gold!

I am stuck too, I found a key but it doesn't open the last door. What can we do? Has anybody gone throught this scenario and finished the " An innocent man" campaign?
