Insurrection

''This article is about the civil war. For the loosely organized insurrectionist factions, see Insurrectionist''.

The Insurrection is the proper name given to an undeclared civil war fought between Earth's primary military, scientific, and exploratory agency, the United Nations Space Command and various loosely organized groups of rebels, collectively known as the Insurrectionists, over control of the Outer Colonies, beginning in the year 2494.

Originally, the breakaway movements started as disquiet against the Colonial Administration Authority's oversight of the Outer Colonies, with the colonists tired of the organization's often overbearing bureaucracy. It first started as peaceful protests, and after years of frustrating negotiations, some groups began to use more forceful methods, eventually abandoning diplomacy in favor of terrorist tactics.

Initially confined to a few systems, the fighting spread across human-controlled space in only several years; as the conflict escalated, even some Inner Colonies were targeted by rebel militants and terrorists. What had once been widespread support for the Insurrectionists quickly dried up at the outbreak of violence. Though they started out targeting only military and Colonial Administration targets, as the UNSC counterinsurgency operations began more and more innocent people were caught in the crossfire.

The Insurrection claimed millions of lives between the late 2490's and the mid-2520's. The various rebel groups had become extremely adept at creating improvised explosive devices difficult for the UNSC to detect, and therefore stop, and had struck many high profile targets, even in orbit above Reach itself. Some opponents of the war believed the simplest solution was to simply give the rebels their autonomy - for the UNSC to pull out, and let the rebels have their independence. However, the value of the colonies made them simply too important to abandon.

The Insurrection quickly died down after the onset of the Human-Covenant War in 2525. However, isolated insurgent groups staged operations against the UNSC throughout the war, whittling down humanity's precious resources from the war effort against the genocidal hegemony. After the end of the war, some of the surviving Insurrectionist groups—as well as all-new ones—proceeded to resume their fight against Earth, leading to a resurgence of the conflict.

Origins
The beginnings of the Insurrection are closely intertwined with the socioeconomic composition and role of humanity's Outer Colonies as well as the realities of interstellar expansion.

The Unified Earth Government's first wave of extrasolar colonization took place between 2362 and 2390, resulting in the formation of the prestigious Inner Colonies. During the century that followed, new colonies were established at an even more rapid pace as the technologies involved became more widely available and affordable; the worlds settled during this period would become the Outer Colonies. Many of the Outer Colonies were established to supply goods for the Inner Colonies and Earth and entire worlds were established for the purposes of agriculture or mining. Earth and the Inner Colonies became exceedingly dependent on resources produced by the Outer Colonies, prompting Earth to take steps to ensure they stayed loyal to its authority.

From the beginning, the Outer Colonies were bound to become more unstable than the Inner Colonies. Whereas the original settlers of the latter had been carefully selected from Earth's finest, by the time the Outer Colonies were created the recruitment standards had loosened considerably and were no longer as strictly supervised. Many of the corporations contracted for off-world colonization had their interests in obtaining rights to valuable resources, colonial personnel being a secondary consideration: this led to the illegal conscription of colonists or acquiring them from among pardoned criminals. The Outer Colonies also became a haven for Earth and Inner Colony citizens unhappy with the Earth government or otherwise looking for a fresh start, and many fled to the Outer Colonies through both legal and illegal means.

In the early days of human colonization, UNSC Naval escorts and shipboard Marine complements had accompanied the outbound colony ships in order to maintain security as well as to justify the continued upkeep of the UNSC's massive military, which had not been needed in its original capacity for well over a century. As colonization became more affordable and widespread following the settlement of the Inner Colonies, the nascent Outer Colonies initially lacked a pervasive military presence—apart from the Colonial Military Administration, whose true loyalties ultimately lay with the colonies over Earth. As piracy began to plague the colony systems, some of the colonies appealed to the UNSC for protection, which began the UNSC's involvement in the Outer Colonies.

Escalation
Following the rapid volumetric growth of the region of space controlled by the human race throughout the 25th century, the UEG found it increasingly difficult to maintain its hold over the Outer Colonies, hundreds of which were scattered across exceedingly large swathes of space. By 2490, the Outer Colonies surpassed the core worlds in number by several hundred. Despite their more discrete composition, the Outer Colonies proved an ample breeding ground for a strong nationalist sentiment among their citizens which in turn led to their perceiving the Earth government—and the UNSC which imposed its will—as a draconian outside force. Civil disobedience was not uncommon, often taking the form of refusal to pay taxes and the establishment of unauthorized settlements outside government oversight. On some cases, the Colonial Administration Authority made concessions to ameliorate the situation; for example, the registration of births to government records was kept voluntary. On the other hand, most Outer Colony citizens took advantage of the benefits offered to them by the CAA, including the free vaccination program.

As a result of the growing rumblings of discontent, many inhabitants of Earth and the Inner Colonies began to feel threatened by the Outer Colonies surrounding them. The UEG and its colonial governing and military entities—the CAA and initially the Colonial Military Administration—continued to maintain their military presence and economic control over the colonies with trade restrictions and taxes, engendering further dissatisfaction among the colonists and provoking the more radical secessionist elements. While outspoken and violent resistance against Earth was initially confined to separate insurgent organizations, even the leadership of some Outer Colonies would eventually be sympathetic to the insurrectionist cause. As well, as these sentiments spread, even elements of the CMA became increasingly sympathetic to the rebels, eventually providing them with information, funding and equipment. The CMA's involvement with the rebels went public in 2497, leading to the organization's gradual dismantling and its replacement with the UNSC as the primary force patrolling the colonies.

In 2491, Dr. Elias Carver presented a set of theories known as the Carver Findings to the UNSC High Command. According to a projection algorithm devised by Dr. Carver, social order in the Outer Colonies would break down completely in the near future. To stabilize the colonies, Carver recommended a swift and extensive military action on part of the UNSC. Carver's critics asserted that the situation between the core worlds and the Outer Colonies could be stabilized through diplomacy over enough time; however, the UNSC military adopted the Carver Findings as their standard model for the years to come and sought to curb any major unrest with military intervention. In the same year, the UNSC resurrected the mothballed ORION Project, creating the first generation of supersoldiers designed to surgically remove rebel leadership. Carver's proposal also informed the creation of the subsequent SPARTAN-II Program, although by the time of its creation the predicted scenario was even bleaker: an endless, apocalyptic civil war between the Inner and Outer Colonies. After the onset of the Human-Covenant War, the Spartans were re-prioritized to deal with the new alien enemy, becoming exceedingly successful and well-publicized in this role.

Perhaps the most notorious incident often cited as one of the reasons for the outbreak of the Insurrection is the fate of Far Isle in 2492, when the UNSC used nuclear weapons to put down a major rebellion on the colony.

The Callisto Incident
The Callisto Incident was a pivotal event which is often considered to have started the Insurrection, widening the scope of the conflict from occasional, disparate colonial rebellions into hostilities on a larger scale. The, a corvette, was captured by Insurrectionists when boarding merchant vessels, and all UNSC crew aboard it were killed. In response, the UNSC sent a battle group of three destroyers: the, the , and the.

On March 2, 2494, the battle group eventually found the Callisto in the 26 Draconis System. All of the ships fired six Ares missiles at the renegade destroyer. However, the Callisto managed to avoid destruction by maneuvering behind an asteroid. The insurrectionists then detonated a nuke hidden inside the asteroid before hand, launching the debris toward the UNSC ships.

The Buenos Aires was engulfed in the explosion and destroyed, and the other two ships were seriously damaged. Second Lieutenant Preston Cole, as the only living or conscious officer aboard the bridge of the Las Vegas, took control of the vessel. He signaled the Callisto, activating the ship's distress signal and requested medical aid for the wounded. When the Callisto docked with the Las Vegas in order to take command of the ship, Cole detonated the ships last Ares missile, which had been planted inside the docking bay, critically damaging the Callisto. Cole then bluffed by opening the empty missile silos on his ship and ordered the Callisto to surrender and allow Las Vegas's AI to take control.

Following the Callisto Incident, the Insurrection began to spread to other systems, including the Eridanus system which became embroiled in a local insurrection in the same year. The rebellion was crushed two years later, at the cost of four destroyers, though the rebels in the system retreated into the asteroid belt and would continue to operate for several decades onward.

Preston Cole and the Bellicose
As the fighting spread, the Outer Colonies became a battleground between the UNSC Navy and the rebels' makeshift fleets. In June 2501, an insurgent captured UNSC frigate, the Bellerophon, was pursued for the third time by the, commanded by Preston Cole, into the Theta Ursae Majoris system. After a chase and battle, in which the Bellerophon managed to dodge a MAC round using excellent tactics, the Gorgon was contacted by the Bellerophon, renamed the Bellicose. A short exchange of taunting messages followed, and then Cole let the Bellicose escape. After laying traps in five systems over a course of three months, Cole had yet to find the captured ship. Several months later, Cole was married to Lyrenne Castilla, who was also pregnant.

In June of 2503, eight months after Cole's marriage to Castilla, Admiral Harold Stanforth sent Cole a transmission telling him that ONI uncovered the civilian identity of the captain of the Bellicose - Lyrenne Castilla, spying on Cole. Cole went to confirm this, and found that Castilla had robbed him of everything, leaving only a printout of the exchange they had between the Bellicose and Gorgon. In January of the next year, four destroyers engaged the Bellicose in the Theta Ursae Majoris system, and reported that the ship was caught in the gravitational pull of the gas giant, and destroyed.

Cole faced a court-martial for conspiring with the enemy and giving Castilla knowledge of UNSC slipspace upgrades, and possible execution. However, Harold Stanforth stepped in and vouched for him, and Cole was merely relocated to Earth with a desk job. The Bellicose survived, however, and remained in the shadows until eventually reappearing with an Insurrectionist fleet, dealing the Covenant a crippling blow in the Battle of Psi Serpentis.

Operation: TREBUCHET


In 2513, the UNSC initiated Operation: TREBUCHET, one of the largest operations in UNSC history; spanning ten years and costing hundreds of thousands of lives, the goal was to root out the Insurrectionists and impose order in the Outer Colonies.

Fighting broke out in the Eridanus system, particularly at Eridanus II and the space around it, as rebels supporting the system's breakaway from the UNSC built a small navy of civilian craft and attempted to take over the system. The disorganized Eridanus rebels were eventually brought together by Colonel Robert Watts. The UNSC responded harshly, sending a fleet of destroyers and carriers to the system to combat the rebel fleet. The resulting battle pitted the UNSC against at least one hundred smaller rebel craft. The UNSC forces defeated their rebel counterparts with little difficulty. During the battle, the rebels were routed and the remnants of their fleet fled into the asteroid belt to Eridanus Secundus. They would eventually establish a fully functional asteroid base and began conducting raids again by 2525.

A ground campaign also began on Eridanus II, as units from the 9th Marine Expeditionary Force were sent to the planet in force, hoping to capture leaders of the rebel movement and pacify the population. One of these units, the first Battalion of the 21st Marine Division commanded by Lieutenant Colonel Ponder, was involved in a disastrous mission to try and capture a rebel leader - the second in command - in Elysium City, which ended in the leader's family being killed and Ponder wounded and demoted.

The fighting eventually spread to the Epsilon Eridani system. By 2524, the fighting involved in Operation: TREBUCHET alone had taken over a million lives, the majority of which being civilians. In that year, a Marine battalion was posted at the colony world of Tribute, commanded by Lieutenant Colonel Aboim and supported by the corvette and air support from Hornets. The battalion attempted to put a stop to rebel bomb makers near the city of Casbah. Two special warfare squads, led by Staff Sergeants Avery Johnson and Nolan Byrne, were involved in disastrous operation in June. Byrne's team was killed during a hostage situation at a Jim Dandy restaurant near Casbah city; thirty-eight civilians, three Marines, and two rebels were killed in the bombing. Byrne and Johnson were pulled from the system, and were later sent to Harvest.

An armed insurgency also occurred on the colony of Epsilon Eridani IV, which the legendary Admiral Preston Cole was sent to put down.

Kidnapping at Eridanus Secundus
In the year 2525, a SPARTAN-II team, led by John-117, went on a mission to infiltrate and capture rebel leader Colonel Robert Watts. The Spartans sneaked on board via the Laden. Once onboard, they located a cargo that contained luxury items such as Sweet William cigars and champagne, verifying Watts' presence.

After boarding the rebel base, they neutralized the guards in their path and eventually found their way to Watts. They successfully killed his guards, and sedated Watts long enough for them to escape. Using explosives, they blasted their way out, killing dozens of civilians, much to the regret of the team.

During the Human-Covenant War
Following the Covenant attack on Harvest and the onset of the Human-Covenant War in 2525, Operation: TREBUCHET was put on halt by the UNSC. The Office of Naval Intelligence Section II sent emissaries with full disclosure on events at Harvest to warn Outer Colony leaders. The UNSC made the offer that they would cease hostilities toward the Insurrectionists if they worked to bolster their planetary defenses and ended their attacks on UNSC ships. The rebels believed it to be a trap and responded with laughter, only to face a harsh dose of reality as the Covenant began laying waste to colony after colony.

As the new threat became apparent, many of the rebels, seeing that the UNSC offered the only real protection against the overwhelming Covenant force, ceased to resist and either submitted to the UNSC's control or hid themselves away from both UNSC and Covenant in remote locations such as habitats like the Rubble or Outer Colony worlds, many of which were eventually glassed. However, not all insurrectionists stopped their attacks against the UNSC, and continued their aggression for years after the beginning of the war with the Covenant.

As the war progressed, insurrectionist activity continued to decrease, apart from isolated conflicts such as the insurrections on Mamore and incidents on Harmony and Reach. This was in part due to the common enemy of the Covenant and the desperate situation humanity found itself in, but also the near-total decimation of the Outer Colonies which had served as the rebels' bases of operations. However, the desire for independence continued to linger on many remaining colony worlds. Using the situation to their advantage, entire colonies under Insurrectionist control intentionally cut themselves off the UNSC's communications relay network during the war, anticipating to resume their operations later on. By 2552, Insurrectionist activity on Reach was still common enough for the UNSC to suspect rebel sabotage when a local relay hub went dark, although this turned out to be the work of a Covenant pre-invasion party instead.

Although Insurrection activity continued over the entirety of the Human-Covenant War, the high-profile operations and major battles which characterized the early years all but subsided after the beginning of the war. Any engagements between the UNSC and the rebels following the Covenant attack appear to have been relatively low-key, often involving covert missions carried out by special forces such as Spartans. As a result, the generation that had grown up during the war had no knowledge of the Insurrection's persistence and considered the entire civil war as having occurred long before their time.

Raid on Camp New Hope
By 2531, Insurrectionists had repeatedly had its operations disrupted by a four-man team of Spartan-II supersoldiers known as Blue Team. The team disrupted Insurrectionist operations including Station Jefferson, the destroyer Origami and a saboteur cell on Reach, as well as an incident in Micronesia, and a high-explosives manufacturing facility at an unspecified location.

In response, the rebels gathered together three stolen FENRIS nuclear warheads at Camp New Hope in a way so sloppy that the Office of Naval Intelligence could not help but notice, then contacted the UNSC and offered to trade the nukes in exchange for medicines for their people suffering from Boren's Syndrome. They then set a trap for Blue Team, whom they anticipated would be sent. They successfully ambushed John-117, Frederic-104, Kelly-087 and Linda-058 using an antigravity plate, however were unaware of the presence of a fifth Spartan and new addition to the team, Kurt-051, who had avoided the trap. Kurt was able to free the other members of Blue Team and they then retreated from the camp with the recovered warheads before the camp could launch a proper counterattack. Rebel leader General Howard Graves was killed in the process.

Massacre at Eridanus Secundus
On September 12, 2552, Vice Admiral Danforth Whitcomb, Fred, the Master Chief, Cortana, Dr. Halsey, and Lieutenant Haverson, aboard the Gettysburg-Ascendant Justice, encountered a small rebel base in an asteroid - the same base John had raided 27 years earlier.

After a tentative agreement, Whitcomb convinced Jiles, the governor, to house their battered ships and repair them. Soon, a Covenant ship arrived. Whitcomb quickly destroyed it, but at the loss of their last functional turret, showing that there was most likely more Covenant ships coming. Whitcomb, feeling it was his duty to warn Earth first, initiated a Slipspace jump, leaving the rebels behind, helpless against the soon to arrive Covenant.

Post-war
After the end of the Human-Covenant War, many insurrectionist movements which had ceased their operations during the war began to resurface. Following the ceasefire, the UNSC began attempts to broker peace with the surviving Outer Colonies and Fleet Admiral Hood embarked on a diplomatic mission to discuss reconstruction. A number of colonies refused this offer and cut all ties with the UNSC, which, according to them, had abandoned them during the war. Many insurrectionist cells were also able to acquire copious amounts of Covenant and UNSC weapons and equipment circulating on the black market.

Of particular significance to the reemerging insurrectionist movement was the colony of Venezia, which had become a major center for rebel operations during the war, when its insurrectionist government had declared itself sovereign and eliminated the local CAA authorities.

Another formidable force to resurge was the United Rebel Front. After the war, they had multiple planets under their control like Talitsa and Terceira, which compelled the UNSC to conduct raids using Spartan forces.

Insurrectionist attack on the Infinity


Also of major significance was the rise of the New Colonial Alliance founded by rogue UNSC Admiral Mattius Drake, which in early 2553 attempted to hijack the newly-commissioned. In this attack, former SPARTAN-IV candidate Ilsa Zane and her NCA combatants staged a mutiny on the vessel and managed to briefly seize control of the bridge. The attack was foiled by Spartan forces aboard the Infinity and the boarders were all killed or captured, leading to the UNSC's discovery of the new movement's existence.

Battle of Ealen
As of 2558 the movement remained active and became increasingly militant. They attempted a direct attack on the UNSC during peace negotiations with the Jiralhanae led by Chieftain Lydus on Ealen IV in 2558. Having orchestrated the attack through a double agent later identified as Spartan-IV supersoldier Vladimir Scruggs, the NCA contracted Sangheili mercenaries led by Shipmaster Vata 'Gajat to assassinate the delegation. However, the UNSC successfully repelled this attack, but not before the peace process was once again stalled.

Infinity ambushed
Later that year, Captain Daniel Clayton of the NCA sought revenge against Fleet Admiral Terrence Hood aboard the for the loss of his father Captain James Cutter and the  decades earlier, ambushing the vessel at Oth Lodon with the help of Gajat's mercenary faction. Utilizing a Covenant Station's glassing cannon, Clayton managed to cripple the Flagship and kill a significant portion of the Infinity's crew. However, Spartan forces saved the Infinity by succeeding in killing Vata 'Gajat and apprehending Captain Clayton. With Daniel Clayton captured, Lord Hood visited the turncoat captain in his cell, querying Clayton about the intentions of the NCA's leader, Admiral Drake. Clayton only told Hood the NCA was stronger than before and had agents on every colony, even Earth, before being shipped to Midnight Facility on Hood's orders.

Legacy
Ironically, the Insurrection may have contributed to the UNSC's victory in the Human-Covenant War. As Codename: SURGEON stated in his 2552 report on Admiral Preston Cole:

While the reason for the UNSC's eventual victory was arguably the Great Schism within the Covenant, from the Insurrection came the Magnetic Accelerator Cannon, Titanium-A armor, advances in ship-to-ship warfare tactics, the incorporation of the Illegal Entry Protocols and Counter-Illegal Entry Protocols into smart AIs, and above all, the SPARTAN-IIs, all of which would prove crucial in humanity's fight against the Covenant.
