Bitter Springs Massacre

The Bitter Springs Massacre is an event mentioned in the graphic novel All Roads which came with the Collector's Edition of Fallout:New Vegas. During the story it is revealed that the New California Republic, most notably the 1st recon reconnaissance unit, massacred local tribals at Bitter Springs, including the women and children in their bid to secure the Mojave Wasteland.

Many of those massacred belonged to the Great Khans, which is the driving force behind their hatred of the NCR and desire to see Bitter Springs destroyed. Chance, a survivor of the massacre is psychologically scarred by the events and becomes a mute junkie while the remainder of the Khans become forever hostile against the NCR.

During several portions of the graphic novel the Khans mention wanting to attack Bitter Springs or the NCR, setting the stage for any conflict during gameplay.
