Community:Fanfiction/Haddon War

Haddon War is a large conflict taking place across the former United States of America from the years 2301 to 2308.

Background
Belligerents in the Conflict included the New California Republic, Khanic Empire, Enclave, United Commonwealth Government, New Haven Federation, and Appalachia Coalition. Canada entered the war in 2307, and their contribution was responsible for a large portion of late-war gains. The war caused a vast amount of upheaval societally, politically, and economically, and, thanks to its devastation, was responsible for a period of peace shortly afterwards.

History
While the war itself only began in 2301, the circumstances and tensions behind it had existed for centuries. The beginning of the war, however, was spurred on by a diplomatic misunderstanding, and could potentially have been avoided.

In 2300, at the dawn of the 24th century, the New California Republic expanded yet again, eager for more land, resources, and influence. Spurred on by their recent successes in the Mojave, the NCR moved northeast, to Wyoming. There, however, Republic troops encountered what could be considered the greatest threat to their regional supremacy since the Legion: The Khanic Empire. The end product of the Khan's lineage, the Khanic Empire had carved out a vast swath of the midwest, establishing dominion over thousands of individuals. Thanks to the Khan's previous experiences with the NCR, having feuded with them since the Republic was merely a tiny farming community, first contact was tense, and the Californian troops were forced to leave. Tensions continued to rise, however, when the NCR discovered that a small border settlement, by the name of TwoTree, was sitting on a large gold stockpile. The Republic began positioning troops around the border, agitating the Khanic Army. Both sides began to move troops into entrenched locations, with increasing numbers being called up from the militaries of the opposing nations.

However, the true spark that ignited the powder keg that the situation had become was a single misunderstanding. The NCR President, hoping to distinguish themself from previous administrations, requested to send a diplomatic party to TwoTree to resolve the situation. The Khanic government was made aware and allowed this. For a time, it seemed as though both sides were willing to come to a peaceful resolution to the situation. However, none of the plans of the upcoming diplomatic summit were told to the head of TwoTree's militia, one Joseph Haddon. When the NCR diplomatic party of 20 arrived at TwoTree's gates, Haddon viewed it as an invasion force and opened fire.

Out of the diplomatic party, only 3 people survived. In retaliation, NCR Rangers attacked a Khanic border station 3 days later. Following this event, all negotiations were called off. Less than 24 hours later, the NCR declared war on the Khanic Empire. The New Haven Federation, having been wary of the Khanic Empire for some time now, and viewing the massacre of the NCR diplomatic party as an unprovoked act of aggression, declared war shortly after.

On the 23rd of January, 2301, NCR troops invaded TwoTree, taking control of the town and killing any who resisted. The invasion that Haddon had assumed the diplomatic party to be had arrived, and rapidly secured the town's borders. Khanic warriors attempted to retake the town repeatedly, but the entrenched position of the NCRA made such an act impossible. Under the command of General Lee Oliver, the NCR used TwoTree as a staging ground, rapidly transporting troops to the surrounding areas. With Khanic troops being repeatedly routed, the empire could provide little organised defense of major areas. Pushing towards Chay-yen, the Republic seemed unstoppable.

However, another party had been watching the situation with more than a veiled interest. The Enclave, having reestablished itself in the north, feared as to what would happen should the NCR conquer the Khanic Empire, due to the Republic's prior war with the organization. Knowing that the Republic could not be defeated by the Khans alone, the Enclave declared war on the NCR, entering the conflict on the side of the Khanic Empire.

Enclave troops proved to be a boon to the embattled Khans, rapidly arriving and helping to stabilise the situation. This, paired with the Khan's usage of irradiated metal in bullets and their cavalry divisions, swiftly turned the previous power dynamic on its head. The NCR and NHF were forced back to numerous strongholds, their positions rapidly overrun by Enclave soldiers equipped with Power Armour. The New Haven Federation itself had particular strain placed on it, with its supply lines being used by the NCR to supply its army. That, paired with an increasing subsidization of the NHF's military by the NCRA, led to certain questions as to whether the Republic respected the Federation's territorial integrity. Ultimately, the alliance between the two nations held, and the combined armies of both sides held the line, with the front lines becoming stagnant and unmoving for multiple months on end.

Meanwhile, on the opposite coast, a similar conflict had been ongoing for the past decade. The Brotherhood of Steel detachment on the East Coast had existed in an uneasy peace with the United Commonwealth Government for a few years following the destruction of the Institute, and despite there being occasional tense periods, the peace had held for as long as Arthur Maxson lived. But due to the peace only existing on a single condition, it fell apart rapidly after the Elder's death.

A team of Institute remnant synths had assaulted the Prydwen in 2290, succeeding in killing the Elder along with Lancer Captain Kells. With the Brotherhood lacking leadership, Knight Rhys seized power, and ordered the Commonwealth to be brought to heel. While some within the Brotherhood's ranks had protested, most had stayed silent, with the few who disagreed with Rhys' new campaign of aggression choosing to form a new order led by the exiled Paladin Danse. However, Rhys' campaign of extermination was met with one factor that he hadn't accounted for: the UCG.

The war between the two factions began when Rhys', flush with his victories in exterminating mutants and ghouls in the region, decided to remove the UCG from its position in Nordhagen Beach, sending Brotherhood troops to take control of the location. When the family occupying the farm fought back, the Brotherhood soldiers, on Rhys' orders, gunned them down. Only the young boy survived, and this incident caused a wave of defections within the Brotherhood. Rhys, however, viewed the destruction of Nordhagen Beach as a victory for the Brotherhood.

It wasn't.

On February 28th, 2291, UCG troops assaulted the Cambridge police station, massacring the BOS troops stationed there and seizing their Power Armour for themselves. Scribe Haylen, thanks to both her prior connection with Danse and Recon Squad Gladius, and her constant objections to Rhys' doctrine, was spared and put to work developing new technologies for the UCG. Thanks to both a combination of her work, the UCG's elite troops, and overall resentment for the Brotherhood, Rhys was forced to withdraw to the southernmost regions of the Commonwealth, where the UCG's presence was weakest. The Brotherhood who did not withdraw were wiped out when UCG artillery at Fort Independence destroyed the Prydwen and Liberty Prime, leaving Rhys' options minimal. By 2302, he had almost completely exhausted his supplies and soldiers, and was having trouble repelling even minor UCG incursions.

Rhy's salvation, however, came in the form of an unexpected alliance. Due to the Brotherhood's proximity to the embattled Gunners, another target of the UCG, the two groups entered an uneasy alliance, with Rhys effectively hiring the Gunners as privateers, giving them leave to raid settlements under UCG control, in exchange for their support of the Brotherhood. Despite this, Rhys manipulated the Gunners, treating them more as servants than allies, and eventually had the Gunner leaders covertly assassinated, effectively subsidizing them into the Brotherhood. Simultaneously, contact was made with a scouting party from the other BOS division on the East Coast: The Appalachian chapter. Convincing them that he had suffered a mutiny, Rhys convinced the Appalachian Brotherhood of Steel to come to his aid, which in turn convinced the loose alliance of merchants and settlers that governed the region to march on the Commonwealth. In a few weeks, Rhys had gone from losing a war, to leading one of the greatest threats to the stability of the Commonwealth since the Institute.

The Appalachian Army, led by the Brotherhood of Steel, marched through the Capital Wasteland, causing some amount of panic among its citizens. The coalition formed by Megaton, Rivet City, Big Town, Lincoln, Underworld, and other, smaller settlements decided not to intervene, fearing the Appalachian's firepower. However, the government of the New Republic of Dave, knowing what allying with the army could bring them, welcomed the coalition, supplying them with provisions and ammunition. In exchange, the Appalachians granted them a coalition detachment, along with a supply of advanced weapons and armour, allowing the New Republic of Dave to further secure and expand their borders. The Appalachian Army arrived in UCG territory on the 3rd of March, 2303, signaling the beginning of a new chapter in the Commonwealth war.

In Wyoming, the situation had gone from bad to worse for the Common Defense bloc. Enclave troops, backed by Khanic cavalry units, had arrived in larger numbers, driving the NCR and NHF from their fortified positions. The twin armies were pushed back to TwoTree, with almost none of their number existing outside the town. Promoting the now Captain Craig Boone to Colonel, General Lee Oliver proceeded to order an evacuation, before destroying his office and himself with planted explosive charges to avoid being captured by the Enclave. Reluctantly, the Common Defense bloc left TwoTree.

Boone's methodology differed from that of previous leaders, especially in regards to Power Armour. While other organizations and leaders had used Power Armour as an infantry support platform, this strategy was flawed. As Power Armour units were often spread thin, this resulted in the Power Armoured individual eventually being overwhelmed, as even with Power Armour a single individual could only contribute so much. However, Boone developed a new troop formation that was rapidly copied by most organizations with access to the technology: The Power Armour Division.

By placing all of his remaining heavy troopers in a single location, along with those who had the skills to maintain or use power armour, Boone created a bulwark, a way to break enemy formations, thus allowing for troops without Power Armour to safely advance and eliminate the stragglers. With this plan in mind, Boone proceeded to wait, requisitioning tanks, artillery, vertibirds, and Power Armour from the NCR. Working in cooperation with the NHF, Boone created a new, unified front across the entirety of the shared border, completing this restructuring by September 7th, 2303.

With the restructuring completed, the first Power Armour Division, backed by paratroopers and veteran rangers, reentered Wyoming on the 1st of October, 2303. Rapidly shattering Enclave and Khanic defense lines, the NCRA swiftly recaptured TwoTree and the surrounding area. Boone proceeded to order bombing runs on the retreating Enclave forces, reinforced by artillery. Captured Enclave soldiers were stripped of their Power Armour and advanced weaponry, which were sent back to the NHF to be reverse engineered. With the NCRA advancing rapidly, the Khanic Empire's commanding officers were at a loss, unable to find a way to counter the Republic's assault.

Eventually, a plan was formulated. There was no way for the Empire to repulse the NCR from the entirety of it's territory. The situation was too far gone. Instead, the Khanic officers created an alternative: Withdraw to their cities and fortified enclaves, evacuating the surrounding countryside. The herds of Radbuffalo inhabiting the plains were almost entirely killed off, with only a few small populations being taken behind the fortified lines. Similar fates met the Brahmin and Bighorner herds, and the supplies of crops were either taken back to the cities or burned. Following these actions, the Khanic army littered the plains with mines, both military issue and improvised.

Supply lines between isolated communities were kept open via way of Pre-War infrastructure such as underground railroads and hidden, mine-free trails. Additionally, these routes were used to deliver troops to harrass the NCR forces, which were assisted by Enclave vertibirds. Ultimately, the Khanic Empire secured their remaining territory, and the minefields, paired with the Khans knowledge of the plains and trails, created a thorn in the Republic's side that bogged down their advance, until it eventually ground to a halt.

In the Commonwealth, Appalachian forces were wreaking havoc, backed by Rhys' Brotherhood. The sheer size of the Appalachian army, paired with its access to technology that wasn't widely available elsewhere, had been the cause of numerous defeats for the UCG, which had been forced to retreat from almost all of its southern positions. With troops from Diamond City being frequently called to the front, and the city's effective conversion into a UCG military base, resentment began to grow among the residents of the Upper Stands. While Sanctuary Hills, the UCG Capital, along with the majority of it's military installations in the north were safe, the residents of Diamond City, Bunker Hill and Goodneighbour were effectively on the front lines of the war, putting the most populous areas at risk. This resentment eventually burst with the Diamond City Revolution.

Diamond City had been annexed by the UCG years prior, putting an end to the city's ruling council's interference in UCG affairs. Still, many of the city's residents still held a belief in their supremacy over other citizens of the Commonwealth. This belief was compounded by the fact that many Diamond City citizens were of the opinion that the Commonwealth War was caused by the UCG, and that they had nothing to do with it. While some UCG loyalties were held by field residents, the Upper Stands loathed the government, with this loathing leading to them attempting to revolt.

On the 27th of August, 2303, several prominent Upper Stands residents, backed by a group of disgruntled ex-security, expelled the UCG-appointed government, forcing their soldiers to leave the city. The flag of the UCG was torn down, with the sign of the Green Jewel taking its place. The reformed ruling council decreed that Diamond City was an independent settlement, and that it would heretofore after be neutral. Any attempt at diplomacy within this time period was met with hostility, with UCG envoys being shot before they could even reach the city gates. However, despite their pride at what they had done, the ruling council's Independent State of Diamond City would not last long.

UCG artillery in Hangman's Alley was fired on August 29th, 2303, severely damaging the Upper Stands. Following this, UCG troops from surrounding settlements marched into Diamond City, and demanded the surrender of the ruling council. When they refused, the UCG stormed the old mayor's office, quickly dispatching the inferiorly equipped security. Despite the ruling council's attempt to surrender following this, the UCG executed the entire council, along with any Upper Stands residents who resisted. The city flag was burned, with the entire Diamond City security force being imprisoned, and a strict curfew was enacted. Additionally, the UCG leveled harsh taxes on the entire city, and confiscated any weapons more lethal than a pipe gun possessed by the populace. In attempting to secure their city's independence, the ruling council had made the entire population much worse off than they were initially.

The Diamond City Revolution was a boon for Rhys, as the chaos that it caused amidst the UCG ranks led to them abandoning several crucial positions, allowing the Brotherhood to seize control. Additionally, the view of the UCG among Commonwealth citizens plummeted following this event, allowing for Rhys to frame himself as the Commonwealth's saviour. However, the majority of his campaign's successes were the result of his Appalachian troops. And shortly after the Diamond City Revolution, they would have far bigger concerns than fighting a war.

The UCG still maintained a silent outpost within the territory that Rhys had conquered: Vault 88. The moment that the Appalachian Coalition arrived in the Commonwealth, the UCG military command ordered Vault 88 to seal its door, and not open them until an all-clear signal was sent via radio. There, in the undisturbed darkness, the Vault Dwellers were given an important project: the end of the Appalachian Coalition's war effort. While researching, however, the inhabitants of Vault 88 discovered something that could not only destroy Appalachia's war effort, but Appalachia itself.
