Detailed walkthrough

After building an artillery piece at a settlement and becoming hostile with the Brotherhood of Steel, this quest can be periodically obtained when talking to Preston Garvey or listening to Radio Freedom. The Sole Survivor is informed that the artillery at an allied settlement is under threat of a Brotherhood attack. Alternatively, the quest may be obtained directly from a settler at a settlement with active artillery.

To proceed with the quest the Sole Survivor must travel to the settlement and talk to their leader, who will give the details: a Brotherhood vertibird has been spotted near the settlement, scoping out the artillery. They will ask the Sole Survivor to help build up the settlement's defenses to protect against the upcoming attack.

After reaching the settlement, the Sole Survivor has 30 (in-game) minutes to prepare for the attack. Regardless of any defenses built, a squad of Brotherhood soldiers will spawn after the 30 minutes have expired and begin attacking the settlement. The Sole Survivor can help eliminate the attackers or let the settlement's defenses handle it. Either way, if the artillery is destroyed the quest will fail.

With the threat neutralized, the Sole Survivor can talk to the settler from before to receive thanks and a reward of ~100 caps. If the quest was given by Preston Garvey, the Sole Survivor must report back to him to turn in the quest; it will be completed immediately upon receiving the reward otherwise.

  • This quest will only be given for settlements with active artillery. The following requirements must be met for the artillery to be active:
    • The Sole Survivor must have ownership of the settlement
    • The artillery piece must not be in need of repair due to a previous attack
    • A settler must be assigned to the artillery piece
  • With the Nuka-World add-on installed, this quest will not be given for settlements that have been captured or subdued by the Nuka-World raiders.
  • This quest will only be given if the player is both a member of the Minutemen and hostile to the Brotherhood of Steel.
  • This quest will not be given if The Prydwen has been destroyed.
  • If the Sole Survivor leaves the settlement before the Brotherhood attack spawns, the attack plays out in the same fashion as a normal off-screen settlement attack. If the settlers win, the Sole Survivor receives the caps and the quest completes immediately. If the attackers win, the quest fails.
  • The death of the settlement leader will result in the quest failing; it will not prevent the Brotherhood attack from spawning. If Preston gave the quest, the Sole Survivor must report their failure to him before the quest is removed from the quest log.


PCPC In certain locations, NPCs might spawn in inaccessible locations (for instance, Roger Warwick at Warwick homestead might spawn inside the water cistern). This bug is shared with the other settlement quests.[verified]

  • PCPC This can be resolved by using the console command targetID.moveto player to teleport the NPC in question.
  • The Warwick homestead example can be resolved by building stairs into the cistern and a bell outside of it. Using the bell and waiting for an in-game hour (using the Wait option) will cause the NPCs to spawn near the bell.
