- Inform the citizens that you have succeeded.
- Talk to Preston Garvey
Meeting with the locals
This quest should be added to your journal at the end of the When Freedom Calls main mission. During your final conversation with Preston Garvey you'll find out that settlers from Tenpines Bluff might need your assistance as well. Leave Sanctuary and head east. Once you've located Tenpines Bluff search the small encampment and talk to one of the Settlers. You'll find out about the bandits and you'll be asked to get rid of them.
Killing the thugs
The hideout of the bandits is a random location from the game's world. It may be one of the factories, a large house or an underground area. Use your Pip-Boy to learn where you need to go. Depending on the location you'll be able to start attacking the bandits as soon as you've arrived or you'll be forced to find the entrance to their base of operations first. You must eliminate all enemy units.
Go back to Tenpines Bluff and inform the Settler about your success (you will receive bottlecaps from him). There's one more thing to do - travel to Sanctuary and talk to Preston Garvey. He will give you a flare gun with some ammo. He'll also tell you about wanting you to lead the Minutemen and give you a new random task.
Quest rewards: Experience points, bottlecaps, flare gun, new random side quest.
