NCR-Khan War

The NCR-Great Kahns War was a conflict between the New California Republic Army and the Great Khans, that began shortly after the NCR entered the Mojave Wasteland and ended shortly after the massacre that occurred at Bitter springs.

Prelude
As supplies and fresh water began to dwindle, overcrowding was becoming more and more apparent. The New California Republic sent it's elite Rangers and scouts into the Mojave Wasteland in search of fertile lands, resources and to expand their borders for their ever growing population.

War
Aaron Kimball, the anti-tribal president of the NCR, gave orders to annex the local tribals (including the Khans), the New Vegas area and secure Hoover Dam as an excuse to hunt down the Khans for raiding NCR settlements. The Khans had recently lost a major conflict against Mr.House and the three tribes that had joined with him, making the Great Khans extremely vulnerable to attack and were licking their wounds when the NCR showed up. This proved disastrous for the Khans, as with an already weakened fighting force against the well equipped and powerful NCR. And as a result, were forced into a full retreat. Despite the fact the Khans didn't put up a fight, the NCR still opened fire upon the retreating Khans, causing the Khans to despise the NCR. Despite all this, the Khans continued to fight, attacking supply caravans, settlers, NCR troopers and taking their supplies whenever they could to better arm themselves. The height of the war came when the Great Khans were hanging onto the last of their ropes and were losing, as the NCR burned their settlements and killed most of the Great Khans main forces, the Khans were forced into one of their last settlements, known as Bitter Springs.

Bitter Springs was where most of the Khans remaining fighting forces were, but proved to be a mistake as it was surrounded by hills, making a high vantage point around the base, making the entire settlement a giant kill zone. This was soon realized during the Bitter Springs Massacre.

In 2278, the NCR sent 1st Recon reconnaissance unit to attack the Great Khan encampment and "fire until you're out of ammo". At the same time, most of the Great Khan attack force was out. First Recon opened fire and obeyed their orders, firing at anyone who ran towards the only exit out of the settlement but in a tragic twist of fate, communications were not relayed in time for the soldiers to not open fire and most of those who were killed were either women, children, or local tribals. The actual fighting force was out in another unknown location and came back to find the village had been turned into a blood bath. With no where else to go the Great Khans turned to the dangerous, but resource rich, Red Rock Canyon.

After this final assault, the NCR couldn't figure out how to work a surrender with an enemy they couldn't reach, so they simply declared victory.

Outcome
With the NCR declaring "victory" over the Great Khans, the NCR turned its attention to the Caesar's Legion, during this time the Great Khans turned its attention to regaining their numbers. After the Khans arrived at Red Rock Canyon they met the Followers of the Apocalypse, who taught them in survival skills. The Khans took advantage of this and now create drugs from their newly acquired skills. They then gave these chems to their biggest customers and allies, the Fiends, who now give the NCR even more trouble than the Khans. After the war, and most notably the massacre at Bitter Springs, many Khans switched over to the NCR (for example Sergeant Bitter-Root) while on the NCR side, many discharged soldiers decided not to re-enlist when they were offered to join (for example Craig Boone and Manny Vargas). Since the war, the NCR has left the Great Khan alone, mostly out of regret for the massacre at Bitter springs and for lack of resources.
