The Mojave Campaign is a move by the New California Republic to annex the entire Mojave Wasteland. The campaign, which started in 2271, erupted after the massacre of 38 NCR citizens at the hands of Mojave raiders in the same year. President Tibbet subsequently lost a motion of no confidence. Her replacement, Wendell Peterson, ordered three battalions of NCR infantry into the Mojave, beginning the campaign.[2] The campaign's main objectives are to remain in control of the Hoover Dam and prevent Caesar's Legion from advancing across the Colorado River, keeping them from endangering the Republic to the west.[3]


To secure transportation routes from the Mojave to the NCR in the west, the Mojave outpost was established in 2272.[2] As early as 2273, the New California Republic sent Rangers out east to scout for anything of interest.[4] Most importantly, the Rangers discovered that the pre-War city of Las Vegas (now renamed "New Vegas") had been relatively untouched by the Great War, and that Hoover Dam was in repairable condition. Realizing the militaristic and economic values of these locations, the Republic quickly sent a detachment of their army in 2274 to take control of the New Vegas region in hopes of using the rich resources there to their advantage[5] The NCR, after having moved in the Mojave area, seized other nearby areas such as Bullhead City in what came to be known as the "Pacification of the Mojave".[2]

Once they were able to mobilize a sizable force, the NCR occupied the Hoover Dam before any other party could claim it. If not for the Treaty of New Vegas the NCR reluctantly signed in 2274, the Republic would have marched on the city and taken it soon after occupying the dam. With the treaty, the NCR was given control of Hoover Dam and was allowed to divert 95% of the electricity generated to the Republic's core regions, while diverting the remaining 5% to the Strip. Also, the NCR was allowed to deploy their military forces in the region and allow NCR citizens to visit the Strip without interference, but would have to recognize New Vegas' independence. To ensure Mr. House stayed true to the treaty, the NCR Embassy was established on the Strip mere weeks after the treaty was signed.[2][5]

The city took off when Hoover Dam was started up again and began providing power to the Strip. The upper class citizens of the Republic trickled in to see the city, curious of such a place.[2] Even so, the New California Republic is having difficulties administering such a large region. The campaign is a logistical nightmare, with supplies and troops being slow to get anywhere and Republic funds for both are tied up in the Los Angeles Boneyard, where Senate elections are underway.[6] The Mojave Campaign is so unpopular with NCR citizens, that senators do not want to ruin their chances at election by diverting funds into a desert that many will never see and and have their brothers, sisters, sons and daughters die there.[7] In addition, defending Hoover Dam, keeping it operational, and bolstering defenses against Caesar's Legion is a tall order to fill; to date, only the former two can be accomplished.[6]

First conflict with the Legion

See NCR-Legion War and First Battle of Hoover Dam for further information.

The NCR's new founded wealth and territory would soon come under threat however, from the looming power of Caesar's Legion. Under the command of the Malpais Legate, Legion forces marched against the NCR garrison at Hoover Dam, in an attempt to take the strategic asset and river crossing, in what became known as the First Battle of Hoover Dam.[2] The Legate advanced against the NCR defenders but his forces were unable to penetrate the Republic's defenses. The NCR First Reconnaissance Battalion and NCR Rangers, under the command of Chief Hanlon, executed a tactical retreat west into Boulder City after using their prowess in marksmanship to kill the Legion's Centurions and Decanii from afar, an act that prompted the Malpais Legate to order the Legion's elite forces to push forward in pursuit of the enemy sharpshooters. He realized too late that the Rangers and First Recon had booby-trapped Boulder City, laying explosives all along their route of retreat and throughout the city itself. When the Legion's elite forces entered the city, the Rangers and First Recon detonated the explosives and inflicted severe casualties on the enemy, crippling their offensive. Shortly after the few survivors of the trap at Boulder City were finished off, NCR Troopers under the command of General Lee Oliver then counter-attacked, pushing back and eventually routing the Legion's main force after having successfully held the Dam.

New conflict with the Legion

See NCR-Legion War and Battle of Nelson for further information.

The Legion would not stay quiet for long. One of the NCR's forward bases, Camp Nelson, was completely obliterated by a Legion task force in an eerie repeat of Fort Aradesh's loss. Another camp, Searchlight, was heavily irradiated in a Legion feint, which transformed all the survivors of that base into feral ghouls. Led by President Kimball and General Lee Oliver, morale among the soldiers is at an all-time low, and desertion rates are high. The main camp on the front lines is Camp Forlorn Hope, though nicknamed by the soldiers and citizens of the Mojave, which as its nickname suggests, is full of depressed and constantly embattled soldiers. They are holding a defensive line across the Colorado River and preparing for the upcoming battle on the Hoover Dam that could decide the fate of the entire area. The soldiers are spread far too thin across the front thanks in no small part to both Oliver's insistence on massing troops and resources at Hoover Dam at the expense of the rest of the front lines and bureaucratic red tape to prevent the Legion from crossing the river, as is illustrated by the attacks on Nipton and Ranger Station Charlie.

The NCR's gold-backed currency lost much of its value after the Brotherhood of Steel ambushed and destroyed their gold deposits, so the NCR's dollar is now backed by water. They hold an iron fist over Hoover Dam's production capabilities, and lease electricity and drinking water to the Strip and other nearby communities in exchange for military supplies and a firm foothold in the region.

The NCR aims to wrestle control of the Strip from Mr. House eventually, but cannot do so while Caesar's Legion remains a threat. While the NCR does openly engage Legion patrols upon sight of them, such efforts have proved futile in any sort of long-term damage to the Legion. The Securitron armies possessed by House pose a threat to both the NCR and the Legion at the moment, but this uneasy stalemate between the three factions is threatened by the arrival of the Platinum Chip. In addition, the Mojave campaign has become increasingly unpopular among NCR citizens, mostly in regions far away from Vegas, to whom the campaign is nothing but taxes and lost children. Senators opposed to the war leverage this unrest to their advantage in the upcoming Senate elections of 2281.

Conflict with the Brotherhood of Steel

See: Brotherhood War and Operation Sunburst for more information.

Even before entering the Mojave, the NCR and the Brotherhood of Steel staged a long and bloody war spurred by disagreements on how technology should be regulated in the wasteland. Despite having far superior technology and training, the Brotherhood has gone into retreat after having lost many battles on the front lines. When the New California Republic established Camp McCarran as its base of operations in the Mojave region in 2275, it spurred sporadic guerrilla attacks from the Mojave chapter of the Brotherhood of Steel.[2] The outcome of the war is best illustrated by the Mojave Chapter of the Brotherhood of Steel. After taking heavy losses in 2276 in a battle for control of Helios One, dubbed Operation Sunburst, the Brotherhood retreated to Hidden Valley and have remained in exile.[2]

Conflict with the Great Khans

See NCR-Great Khan War and Bitter Springs Massacre for further information.

In the early parts of the war, the Great Khans took to raiding NCR military outposts and civilian settlements. The NCR then stated launch counter-attacks against the Khans. They eventually traced a group of Khan raiders to their settlement at Bitter Springs, leading to the Bitter Springs massacre.[2] The Khan leader Papa Khan now holds resentment against the NCR and is contemplating joining an alliance with Caesar's Legion. He has also forged an economic alliance with the Fiends, selling them chems so they will harass the NCR in return.


  1. Note: The dates provided in the Guide do not correspond with actual in-game statements (and there are other chronological errors present, eg. the Brotherhood War in the Mojave is dated at 2256). For example, Corporal Sterling clearly states that he was one of the first Rangers sent east, before the Army came. Dates have been adjusted to match.

    Note: The Guide erroneously states that the NCR attacked Red Rock Canyon.
  3. The Courier: "Why is the NCR interested in this desert?"
    Hayes: "It is no secret. Our interest here is two fold. First, we want to remain in control of Hoover Dam. It supplies the Republic with power, and is a source of fresh water. Second, we want to prevent the Legion from advancing across the Colorado River and endangering the home states."
    (Hayes' dialogue)
  4. The Courier: "Have you always been with the First Recon?"
    Sterling: "Used to be a Ranger... one of the first they sent out east, back before we took the Dam. Observation and reconnaissance. We took the lay of the land, checked out the locals, and kept ourselves inconspicuous. Couple friends of mine were the first to scout the Dam. That was back in '73, if I recall. Lot of those Rangers are dead now. Vegas always chewed men up... it's just a little more literal, nowadays."
    (Sterling's dialogue)
  5. 5.0 5.1 The Courier: "I'd like to know more about the NCR."
    Dennis Crocker: "I can provide a quick history lesson, if that's what you're looking for. In 2274, President Kimball sent the NCR army into the Mojave in force, with the objective of occupying and repairing Hoover Dam. Rangers and army scouts had confirmed that the dam was basically unoccupied and could be restored to an operable condition. Upon arriving at the dam, however, they discovered that a large force of tribals and robots had occupied it. This was our introduction to the Three Families, the Securitrons, and, of course, Mr. House. Using his Securitrons as intermediaries, Mr. House called for parlay. He claimed his forces had occupied Hoover Dam in order to safeguard it for our arrival. And that he was ready to turn it over to us, so long as we could agree to terms. Those terms became the Treaty of New Vegas. The Treaty recognized Mr. House's sovereignty over the Strip and granted us rights to establish military bases at the Dam and McCarran Airport. The NCR is legally permitted to send 95% of the electricity produced by the dam to our home states. The remaining 5% goes to the Strip. The treaty actually makes it illegal for the NCR to prevent its citizens, or troops on furlough, from visiting the Strip. Once on the Strip, our citizens are subject to arrest - or punishment - by House's Securitrons, though that's a rare occurrence. Our troops enjoy a different status. It's illegal for the Securitrons to take action against them. Of course, it's also illegal for our troops to carry firearms on the Strip, so there isn't much trouble they can get into. Our military police does an adequate job of keeping the troops on furlough in line. I don't envy them that task. The embassy was established a few weeks after the Treaty was signed. Basically Mr. House handed us a dumpy little building he had no interest in renovating. I'm the third ambassador to hold this post. And the first, I think, to accept its limitations. My predecessors had ambitions of engineering the annexation of the Mojave. They thought they'd convince Mr. House to join up. I've never even spoken to the man - or whatever he is. Maybe the situation will change once we've beaten the Legion once and for all."
    The Courier: "Go on."
    Dennis Crocker: "Now we mostly just keep track of the NCR citizens and troopers around and make sure they don't get in trouble, but that's Captain Pappas' job. I keep myself busy with paperwork and reports that get sent back to the NCR. It's mostly busy work, but every once in awhile, we make progress."
    (Dennis Crocker's dialogue)
  6. 6.0 6.1 The Courier: "How is NCR doing?"
    Hanlon: "It's no secret that we've had better campaigns. Holding this whole length of river isn't easy. We're stretched thin and the Long 15 just keeps getting longer. Slow to get supplies. Slower to get reinforcements. NCR's senate has got funds tied up at the Boneyard and President Kimball ordered our most experienced rangers to chase ghosts down in Baja. Even Caesar knows that General Oliver's coming back to Hoover. Colonel Moore's doing a fine job of running things over at the dam. In her own way, of course, when she's not trying to wrangle my rangers into helping her. But just keeping that dam secure and operational day to day is enough work for one person, never mind building a defense against the Legion."
    The Courier: "How is NCR doing?"
    Hanlon: "Mojave Outpost sent word through the stations. The rangers coming up from Baja moved through Dayglow a week ago. Some of the patrol rangers have reported that Oliver's power armor heavy troopers are starting to reinforce the front lines. Wish they got here a bit earlier, but that's the senate for you."
    (Hanlon's dialogue)
  7. The Courier: "Why are funds tied up at the Boneyard?"
    Hanlon: "Senate elections are coming up. Local representatives don't want to push any more funding to the Mojave campaign because it's unpopular. Most of the folks around the Boneyard haven't been to New Vegas and probably never will. All they know is that their money gets sucked away to this desert and their brothers, sisters, sons, and daughters die here."
    (Hanlon's dialogue)
