Sacking of Navarro

The Sacking of Navarro was a battle waged between the combined forces of the New California Republic and the Brotherhood of Steel against the Enclave's military forces stationed at Camp Navarro.

Prelude
After the destruction of Control Station ENCLAVE, Autumn Senior led a contingency of the Enclave's military to the Capital Wasteland, including the majority of Navarro's personnel, and the base was left fairly undefended.

The New California Republic and the Brotherhood of Steel alligned their military forces to track down and eradicate the remnants of the Enclave on the west coast and from New California completely and entirely, after the NCR decided that they would 'pose a threat to the region'.

Battle
The NCR and the Brotherhood sent forward a widespread offensive. Despite suffering horrendous casualties, Navarro's Enclave personnel were completely wiped out, and the NCR occupied the region.

Aftermath
According to Arcade Gannon, the survivors of the attack relocated to a wide array of locations. The advanced technology left behind at Navarro by the Enclave was recovered by the NCR, although it proved far too advanced for them to understand. Navarro's loss was apparently unknown to the Enclave forces on the east coast as Whitley makes reference to "Navarro scientists" in his audio-logs, but is oblivious to whether or not it had been sacked yet.

As it is unknown when the sacking took place, and it is unknown when Autumn Senior's contingency relocated to the Capital Wasteland... this would seem only natural.

The Fallout: New Vegas endings for ED-E in which its memory is not wiped will show it traveling to Navarro and vanish, leaving its fate and the current state of Navarro unknown. If ED-E's divide clone is rescued and Ulysses' missiles were launched, it will continue its journey and eventually reach Navarro. However, it is never stated what the clone found at Navarro, stating that the journey was more important than the destination.
