already played this quest in assassin's creed black flag. start in the cove in the center of the map, make your way west through the densely packed trees (watch out for the natives and that stupid panther), sneak around the secret british naval camp until all of the sailors are dead, cut the alarm bell so they can't alert anyone and then plunder and loot from the old caves on the left side of the map. quite simple really if you stock up on throwing knives.
