Brotherhood-Enclave War

The Brotherhood-Enclave War was a military conflict in 2277 between the Brotherhood of Steel and the Enclave.
==Prelude==
===Brotherhood-Enclave conflict on the West Coast===
The Brotherhood of Steel first entered into conflict with the Enclave on the West Coast during the year 2241. As the Enclave begin to reveal its presence to the post-nuclear world, the Brotherhood of Steel reopened several observation outposts in New California to monitor their activity and learn their motives.The Chosen One: "You said 'at one time.' What about now?"
Matthew: "Several months ago we came across a group known as the Enclave. Much to our surprise their level of technology surpassed even our own. We found this quite disturbing and considered contacting them. However, we decided on a more cautious course of action until we could determine exactly who the Enclave was, and the underlying purpose of their organization."
"To this end, we have reactivated small outposts near areas of Enclave activity from which we can safely observe them. Currently, we have activated such outposts in the Den, the NCR, and here in San Francisco."
The Chosen One: "Sounds interesting. What have you learned?"
Matthew: "We have found that the Enclave deals heavily in drugs, weapons, and slaves. However, these are simply trivial pursuits leading up to some higher purpose, which we have failed to uncover. We are still watching them."
(Matthew's dialogue) During this time period, the Brotherhood of Steel tasks the Chosen One with infiltrating Navarro Air Base and retrieving schematics for the Enclave's modified vertibird's.The Chosen One: "What happened to Matt?"
ACE: "Loading sequence..."
Matthew: "You and your so-called President will not succeed."
Frank Horrigan: "Is that so?"
Matthew: "The Chosen One has come, and he will rid the world of your evil."
Frank Horrigan: "I care nothing for your pathetic prophecies. Worse, you have become a nusiance  through your meddling. That ends today!"
Matthew: "Killing me will stop nothing."
Frank Horrigan: "That may be, but seeing your body rotting on the ground will bring a smile to my face."
(ACE's information)
Note: This is the transcript of a cutscene in the San Francisco Brotherhood outpost, at the conclusion of the vertibird plans quest. Following the events of Navarro's destruction at the hands of the NCR sometime after 2246, the Brotherhood of Steel openly began to hunt down and annihilate remnants of the Enclave on the West Coast.The Courier: "What happened to Navarro?" Arcade Gannon: "After the Enclave's command structure fell apart, it was only a matter of time before Navarro was overrun by NCR forces. My mother and I left with some of the troopers from my father's old unit, the same people I've kept in contact with over the years. Anyone who didn't get out was killed by the NCR. Even some of the ones who escaped were eventually hunted down by the Brotherhood of Steel."
===The Brotherhood arrives on the East Coast===
When the Brotherhood arrived in the Capital Wasteland area in 2255, they did not yet know that the Enclave, the corrupt remnants and self-proclaimed continuation of the United States of America who were defeated by the Brotherhood of Steel and the New California Republic fifteen years ago in New California, had fled to the Columbia Commonwealth (Capital Wasteland), establishing a headquarters at the pre-war U.S military installation Raven Rock. Under the leadership of Elder Owyn Lyons the Brotherhood began combating the local super mutants, unaware of the rebuilding Enclave.
==War==
In 2257, the Enclave commenced an indirect propaganda campaign against the Brotherhood. The Enclave, now under the leadership of President John Henry Eden, plotted in secret at Raven Rock. For twenty years, there was no interaction between the two factions, leading many to suspect that the Enclave radio broadcasts were on an old loop. However, in 2277, Colonel Augustus Autumn led an attack on the Jefferson Memorial, and took over Project Purity, as part of their plan to "purify" the wasteland. James was among those killed, but the Lone Wanderer and other survivors escaped to the Citadel.
After the capture of the Jefferson Memorial, the Enclave begin their conquest of the Capital Wasteland, establishing many small outposts and checkpoints throughout the region. They even try to access Vault 101, only to be denied entry by its isolationist overseer.
The Brotherhood set out on collecting evidence that Project Purity could function, in order for them to reclaim the Memorial. The Enclave caught onto this, kidnapping the Lone Wanderer in Vault 87 and confiscating the G.E.C.K.. The Lone Wanderer awoke in captivity inside Raven Rock and was interrogated by Colonel Autumn. President Eden then distracted Autumn and sent him elsewhere, summoning the Lone Wanderer to his office. It was here that the President was revealed to be a ZAX supercomputer. The former recruited the Lone Wanderer to act on his behalf, giving them a vial of Modified FEV to insert into the purifier which would cleanse the wasteland of all life forms that had been exposed to too much radiation. Eden then facilitated their departure from Raven Rock.
After the Brotherhood received word that the Enclave possessed the means to activate the purifier, they launched an offensive to reclaim the Memorial with the support of Liberty Prime, a pre-War super weapon restored to working condition by Doctor Madison Li and her team of scientists. The Brotherhood forces and the Lone Wanderer stormed the memorial and confronted Colonel Autumn, although his fate is not known. The purifier was then started. Two weeks later, the Brotherhood started delivering the water throughout the wasteland. 
The Enclave, after its defeat, made a last stand at Adams Air Force Base. When the Brotherhood invaded the Enclave's satellite relay station, the base was destroyed, but Liberty Prime was also eliminated by an orbital missile strike, a major blow for the Brotherhood. The Lone Wanderer scoured the ruins of Old Olney to retrieve a Tesla coil to assist in the scribes' research in Tesla cannons - the Brotherhood's last chance of countering the Enclave's Vertibirds. After creating the Tesla cannons, they launched a final attack on Adams AFB. The Enclave put up a tenacious final stand but were ultimately annihilated by the Brotherhood's forces.
The launch terminal for the Bradley-Hercules orbital satellite indicates that the Enclave had given themselves the means to eradicate the settlements of Megaton and Rivet City. They also had Project Purity and the Citadel selected as potential targets. The Lone Wanderer can target Adams' mobile base crawler and decimate the Enclave. (Alternatively, the Citadel can be targeted resulting in the destruction of both the Brotherhood's headquarters and the majority of their forces in the Capital Wasteland, as well as the destruction of the Enclave at Adams Air Force Base).
In Fallout 4, it is confirmed that the Brotherhood of Steel has taken control over Adams Air Force Base, the Enclave's mobile base crawler having been destroyed. As a result of this, the Brotherhood has gained access to all of the facility's resources.
==Aftermath==
The Brotherhood of Steel would win the war against the Enclave in the east, their mobile base crawler being destroyed by the actions of the Lone Wanderer; its destruction being a decisive blow. Adams Air Force Base would become a major staging area for the Brotherhood where they would construct the airship The Prydwen, a process which would take a total of 8 years. As well as this, the Brotherhood now had access to what remained of the Enclave's VB-02 Vertibird fleet, upgrading them for transit aboard their newly built airship.
The Maxson bloodline would continue into the late 23rd century, as Arthur Maxson is alive by 2287; now holding the rank of elder of the Brotherhood of Steel in the east. That same year, he would mobilize his forces and carry out an expedition north towards the Commonwealth, with the aim of destroying the Institute, previously discovered by Brotherhood recon teams sent into the ruins.
The Enclave would survive, but would pull out of the Capital Wasteland. They are known to still operate somewhere around Chicago, but their exact status following their defeat is unknown.Whitley: "Subject E: Diagnosis complete. Begin Recording.My name is Whitley. I'm a researcher at Adams Air Force base. Until recently I was in charge of the Duraframe reinforcement project for the combat model Eyebots.Eyebot Duraframe Subject E is both the prototype, and the last functional model in this test group.I was prepared to make several significant upgrades to the machines.However, as the project was canceled and all Duraframe assets are being diverted to Hellfire Armor, I am sending this model to the Navarro outpost.If you are listening to this log from one of our Enclave Outposts in Chicago, give this unit whatever repairs it needs so it can continue to Navarro."
