Crush the White Legs Crush the White Legs is a in the " " , " Honest Hearts " . It is the opposing quest to Flight from Zion , in which the Courier chooses to help the Sorrows and Dead Horses flee Zion Canyon . Detailed walkthrough . The Courier must speak with Daniel and tell him that they wish to fight and wipe out the White Legs with Joshua Graham . Daniel initially expresses some anger at the decision and will hastily disagree with it . The Courier then appears at the Caterpillar ' s Mound with Joshua Graham and he will provide details of the situation , explaining that he , the Courier , and a combination of Sorrows and Dead Horse warrior s will assault the White Legs encampment at Three Marys . After talking to Joshua Graham , the Courier joins Joshua and the latter provides the The Way of the Canaanite follower perk . Fast traveling is disabled during this quest , so they have to trek to Three Marys while fighting many White Legs along the way . The White Legs mainly seem to appear in groups of three at predetermined locations . The Courier must then follow the river south - west towards The Bend Bridge , continue along the river south - east towards the Virgin River , but keep going south . The entrance to Three Marys is just south of the Red Rapids docks along the river . After arriving at the entrance to Three Marys , they must fight their way through to the center of the camp . After reaching Three Marys ' caverns , the White Legs detonate mines from an above rock formation , blocking the direct way to the camp ' s center ( this obstruction will not be cleared , even after the ending ) . Following this brief cut - scene , Joshua will say that the Courier and he will end this no matter what . He leaves and his follower perk is lost . The Courier must then go through Three Marys ' caverns to reach the other side of the blockade , reaching the innermost parts of the camp . After reaching the destination , a cut - scene initiates with Joshua Graham executing two White Legs . He then makes a brief declaration to Salt - Upon - Wounds , mentioning the fall of New Canaan , Syracuse and Caesar ' s Legion . He also quotes the Bible , less now than before and speaks in the language of the White Legs . After this speech , Salt - Upon - Wounds will cry out to the Courier asking for help , claiming that they are the only one who will listen to reason . A choice can then be made to either talk to Joshua or fight Salt - Upon - Wounds . To talk Joshua out of executing Salt - Upon - Wounds , two high level speech checks must be passed . With a Speech level of 75 , Joshua can be talked down enough to at least let Salt - Upon - Wounds fight back before he is executed . Passing this speech check but failing the next one results in Salt - Upon - Wounds and two more White Legs attacking after dialog is exited . With a Speech level of 90 , the Courier can talk Joshua out of killing Salt - Upon - Wounds entirely . The ending received will be slightly different than if only one speech check is passed . With the Sneering Imperialist perk , he / she can tell Joshua to " put a cap in General Gobbledigook " . After either killing or sparing Salt - Upon - Wounds , the ending cinematic plays , involving all of the appropriate character choices that were made . After completing this quest the player receives the " O Daughter of Babylon " achievement / trophy . Despite this being the staying option , Daniel , Joshua Graham , Waking Cloud , Follows - Chalk , and White Bird will not remain in Zion . Their clothes and other ending gear ( such as Joshua Graham ' s scripture ) can be found in the final footlocker , just before the Courier enters the southern passage to return to the Mojave Wasteland .
