NCR-Enclave War

The NCR-Enclave conflict was a military conflict of unknown proportions waged between the temporarily aligned New California Republic and the Brotherhood of Steel against the remaining Enclave in New California. The conflict began some time after Control Station Enclave's destruction and ended sometime after with the decisive Sacking of Navarro.

War
Several years after the destruction of the Oil Rig by the Chosen One, the NCR, convinced that the remaining Enclave forces were a threat to security of the region, aligned their military forces with Brotherhood of Steel and attacked Camp Navarro. The NCR proved victorious, either capturing or destroying the base. The surviving Enclave personnel scattered across the west coast, being cut off from their leadership entirely, hunted by both the NCR and the Brotherhood of Steel.

Outcome
The few remaining Enclave personnel in California that did not retreat with the rest of the Enclave either were recruited by the NCR, went rogue from the Enclave entirely, fled east or remained in the west and went into hiding and those that integrated into the NCR did so by hiding their identities. As any that were discovered were arrested and tried for war crimes and either imprisoned indefinitely or executed. Some were able to reach as far as Nevada, where the NCR's more tenuous presence along the frontier gave them the opportunity to quietly blend into large towns.

The majority of the Enclave's remaining personnel were able to relocate to other parts of post-war America.The most noteworthy examples would be in the Capital Wasteland and Chicago.

At least one Enclave installation, a former Vertibird refueling station in the Mojave Wasteland, managed to avoid being discovered by the NCR and local Brotherhood of Steel.

Ultimately, the NCR-Brotherhood alliance was short-lived, as not long after, the NCR-Brotherhood War began. After sacking Navarro, the NCR recovered an item with the markings of the Divide's military installations, alongside lots more advanced technology they couldn't even begin to understand. This package was a detonator that contained missile launch codes that merely needed to get within range and activate the launch computers within a silo. When the Courier delivered this package to the Divide, the detonation signal activated the ICBMs below ground, causing the earthquakes and radioactive storms that shaped the Divide into what it is in the 2280s.

Appearances
The NCR-Enclave conflict and/or the attack on Navarro is mentioned in Fallout: New Vegas (in the quest For Auld Lang Syne) and its add-on Lonesome Road.
