NCR-Legion War

The NCR-Legion War is an ongoing military conflict in 2281 between the New California Republic and Caesar's Legion.

Prelude
As the NCR started to subject the Mojave Wasteland, Caesar decided to add the NCR as another notch to the Legion's belt and conquer the area.

War
In 2277, the Legion went into the Mojave to conquer the area. To their surprise, the NCR had made a hold on the area six years ago. Angry at the profligate's invasion on the area, Caesar readied the Legion to destroy the NCR and conquer the Mojave.

Establishing their main Mojave base at Fortification Hill, Caesar ordered Malpais Legate to storm Hoover Dam. The NCR fended off the attack well, but they could not afford the Legion to set up positions near the Dam, so, the NCR led the Legion to Boulder City, a trap. When the Legion stormed the city they were unaware that the NCR had rigged explosives and C4 across the entire town. When the NCR detonated the explosives it killed a large portion of the Legion Strike Team. The NCR then mopped up what was left of the strike team.

Caesar was furious at Malpais' humiliating defeat at the Dam. At the Grand Canyon, he order his men to covered Malpais with pitch, burn him alive, and toss his flaming body into the canyon. He then bestowed the rank of Legate on Lanius.

From then on, the Legion stayed to themselves on the other side of the Colorado River, although occasionally popping over the other side to establish camps and bases, and raiding NCR bases. In 2281, they opened the radioactive waste containers from San Onofre in the firehouse within Camp Searchlight, and established the Cottonwood Cove outpost, and raiding bases such as Ranger Station Charlie, and the towns of Nipton and Nelson. They also sent spies into the New Vegas Strip. They secretly plotted the second invasion of the Dam at The Fort.

At the start of the game, the tactical situation for the NCR is not good.

The legion currently have control of Camp Nelson, Techatticup mine, Legate's Camp, the Legion Raid Camp and Nipton, the area around Camp Forlorn Hope is also heavy with Legion activity.

Legion Side
When the Courier entered the Lucky 38, Vulpes Inculta noticed this. He informed Caesar, who then asked him to invite the Courier over. When the Courier arrived, Caesar ordered him to enter the underground bunker and destroy it, and execute Robert House. If the Courier accepts this, he will be asked to receive alliances from factions such as the Boomers, the White Glove Society, Enclave Remnants, the Omertas, and the Great Khans. The outcome of the alliance missions are unknown. They then destroyed the Brotherhood of Steel, and even killed President Kimball.

NCR Side
When the Courier entered the Lucky 38, Ambassador Crocker noticed this. He invites him over and asks him to do work for him. When the Courier arrived, Crocker asked him to receive alliances from the Boomers, and the Great Khans. It is unknown if the alliance missions were successful. He then asks the Courier to destroy the Brotherhood of Steel, but a truce can be signed too. (Player choice). They then required defense of Kimball during the visit. (Player choice).

Outcome
Working for the Legion, the NCR are beaten out of the Mojave back to California. If working for the NCR, the Legion flee east to their territory. The sub-war in the Mojave is over, but the entire war has just begun. Oliver says the war will be finished when they invade the Legion territory.

Alternatively, for an independent or House Vegas, the Legion is destroyed and the NCR will never be able to annex Vegas, and the outcomes of those storylines are added.
