Bitter Springs Massacre

The Bitter Springs massacre is an event mentioned in the graphic novel All Roads and referenced many times throughout Fallout: New Vegas. During the story and game it is revealed that the New California Republic, most notably the 1st reconnaissance unit, massacred a large number of Great Khan women, children and even the elderly as they tried to flee the battle at Bitter Springs.

The NCR snipers setup on Coyote Tail ridge and were ordered to fire until they had exhausted their ammunition on the retreating non-combatants. The stories differ greatly from character to character due to variations in personality and state of mind.

The characters with dialogue in the game include Craig Boone, Manny Vargas, Papa Khan, Major Dhatri, Bitter-Root and Oscar Velasco.

Craig Boone's account
A number of Khans were tracked to Bitter Springs by the NCR many years ago, when the NCR were first expanding their role in the Mojave. The NCR believed it to be the Khans base of operations, and sent a large detachment of troops to bring the raids to an end. The 1st Recon sniper squad, Boone included, were sent to cut off escape at Bitter Springs' only other exit. Little did the NCR realize that Bitter Springs was primarily the home of Khan families, and not (as NCR command believed) a bastion of resistance. When the Khans were then pushed out, 1st Recon was ordered to fire on the ones retreating from the area. Radio contact with the NCR was sketchy at best, command not understanding that the situation involved unarmed civilians. Their superiors ordered them to "fire until you're out of ammunition.", 1st Recon obeyed and what happened at Bitter Springs has had a large psychological impact on Boone, motivating him to leave the New California Republic military behind him.

Chance's account
The history through the eyes of Chance differs from that of Boone, in that the NCR are portrayed as being just as brutal as Caesar's Legion when it comes to pursuing their political agenda for a given area. There was no miscommunication with command, and the NCR soldiers simply rode into the town and opened fire. 1st Recon is not seen at all during Chance's flashback, and none of the survivors had any difficulty in retreating. It had a significant psychological impact on Chance, driving him to the use of drugs and leaving him mute.

Papa Khan's account
Papa Khan states that the Great Khans had been flaunting the NCR's demands, carrying out raids under the assumption that NCR vows to retaliate were simply bluffs. Tensions rose higher, and eventually the NCR tracked what they believed was a large raiding party back to Bitter Springs. Having been harassed continuously by the Khans, the NCR troops did not expect Bitter Springs to be anything but a war camp. Fueled by anger and frustration, goaded by the Great Khan's audacity, and lacking appropriate orders, the NCR's 1st Recon opened fire on what they were told were retreating Khan troops.
