The Lost Patrol

The Lost Patrol is a Brotherhood of Steel side quest in Fallout 4.

Detailed walkthrough
The player character will detect a distress signal once they are near any one of the three locations where Brotherhood of Steel followers perished. To complete the objective, the player must loot holotapes from the fallen soldiers, then play them from their Pip-Boy.

Knight Varham's Battlefield holotape is located in a ruined house north of Relay Tower 0MC-810, south of Greentop Nursery and east of Taffington boathouse.

Knight Astlin can be found behind a table in the recruitment office inside the National Guard training yard.

Scribe Faris is found at the Revere satellite array. He is in a metal and wood structure above the ground connected to the southeast array tower. This area is inhabited by super mutants.

Once all three holotapes have been played, a quest marker will appear at Recon Bunker Theta which is otherwise inaccessible. Once there, one will be accosted by Paladin Brandis who will demand to know why the Sole Survivor is there. If the player character tells him the fate of the soldiers, he will allow the Sole Survivor to loot the items in his home, which includes a fusion core.

The Sole Survivor has the option of persuading him to rejoin the Brotherhood of Steel. They must pass three conversation checks and if any of them fail, he will remain where he is. If successful, they will find him aboard the The Prydwen where he will reward them with the Survivor's Special.

To complete the quest, the Sole Survivor must report to Paladin Danse, or Captain Kells if the quest Shadow of Steel has been started and the Prydwen entered the Commonwealth.
