NCR-Enclave War

The NCR-Enclave War was a military conflict between the New California Republic and the Enclave, that began at some point after the Oil Rig's destruction and ended sometime after with the destruction of Navarro. Precisely when this occurred is unknown.

War
Several years after the destruction of the Oil Rig by the Chosen One, The NCR decided Navarro and the remaining Enclave forces were a threat to the security of the region and attacked. The NCR proved victorious, either capturing or destroying the base. The surviving Enclave forces fled into hiding, hunted by both the NCR and the Brotherhood Of Steel

Outcome
Pockets of remnants were located around California and Nevada. There were often stories of remnants being arrested for war crimes from time to time or having managed to live in the NCR territory by hiding their identity.

At least one last bunker is known to remain in good condition in the Mojave Wasteland (The NCR failed to find this area).
