Clerans must protect his village. It's the easiest thing ever. All he has to do is fire the cannons, and no one ever gets past the Entwerp battery.

But now he must board a highly explosive fire-ship to steer it away from the battery. How hard could that be? I mean, the only time the battery is vulnerable is during the lowest tide of the year. Oh wait, it IS the lowest tide of the year. And if Clerans can't stop the fire-ship, then Longfinch's pirates will murder everyone in the village. Perhaps it wouldn't be so bad if the reinforcements weren't tied up trying to prevent the strikers from burning down the National Bank...
