As William Butler Yeats said: 'The center cannot hold.' 
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 over control of the Outer Colonies for some 43 years, between the year 2494 and 2537. 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 bureaucracy. It first began with peaceful protests, but after years of frustrating negotiations, some groups began to use more forceful methods ultimately abandoning diplomacy in favor of all-out war.
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.
By 2524, the Insurrection had claimed millions of lives. 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. 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 Outer Colony InsurgencyEdit
While the widespread fighting in the Outer Colonies did not start until 2494, there had been multiple isolated rebellions for some time. This led the UNSC to resurrect the ORION Project in 2491, to combat the increasing threat posed by civil uprisings. In 2492, the UNSC used Nuclear Weapons to put down a rebellion on the colony of Far Isle. In the end, there were many separate cases that led the insurrectionists to adopt more aggressive tactics.
The Callisto IncidentEdit
- Main article: Callisto Incident
The Callisto Incident was what effectively started the war between the UNSC and Insurrectionists. The UNSC Callisto, 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 UNSC Jericho, the UNSC Buenos Aires, and the UNSC Las Vegas.
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 launched the ship's last Ares Missile, which had been moved by the crew to the docking bay, directly into the Callisto, 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.
Preston Cole and the BellicoseEdit
In June 2501, an insurgent captured UNSC frigate, the Bellicose was pursued for the third time by the UNSC Gorgon, commanded by Preston Cole, into the Theta Ursae Majoris System. After a chase and battle, in which the Bellerphon managed to dodge a MAC round using excellent tactics, the Gorgon was contacted by the Bellerphon, 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 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.
- Main article: Operation: TREBUCHET
Operation: TREBUCHET was one of the largest operations in UNSC history, spanning a timeline of ten years. The goal was to counter the Insurrectionists, which was eventually successful, but at the cost of hundreds of thousands of lives.
Kidnapping at Eridanus secundusEdit
- Main article: Operation: TALON
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 on board, 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, leaving dozens of civilians dead.
Raid on Camp New HopeEdit
- Main article: Raid on Camp New Hope
By 2531 United Rebel Front had repeatedly had its operations disrupted by a four-man team of Spartan-II supersoldiers known as Blue Team. The team disrupted URF operations including Station Jefferson, the destroyer URF 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.
- Main article: Battle of the Rubble
In 2528, the Outer Colony Madrigal is glassed and the survivors are evacuated to a nearby Insurrectionist base called the Rubble, a collection of asteroids connected together orbiting the gas giant Hesiod in the same system as Madrigal. On the Rubble, a collection of Insurrectionists, refugees from Madrigal and miners make a life for themselves free of the UNSC and the Covenant until a Jackal ship discovers the base and agrees to trade as part of a plan by the Prophet of Truth to locate more human worlds and Earth. The people of the Rubble are content with the arrangement while the Covenant weapons are smuggled into the colonies to arm Insurrectionists there while the Jackal Reth builds an army of Grunts on nearby Metisette to take over the Rubble and use the Exodus habitat to invade Earth. This weapons smuggling draws the attention of the Prophet of Regret and the UNSC with Regret sending Thel Vadam to deal with what he believes are heretics while the UNSC sends the UNSC Midsummer Night to chase down a potential violation to the Cole Protocol. This leads to the battles of the Rubble and Metisette in which the UNSC forces, supported by Spartan Gray Team (sent to destroy navigation data behind enemy lines) destroy Reth's army and lead the inhabitants of the Rubble, around a million people, back to UNSC controlled space. While the Rubble's inhabitants had planned to leave UNSC and Covenant controlled space forever, the Exodus didn't have the engine power so they were forced to travel to an Inner Colony where most of the people were reintergrated into the population while some, presumably Insurrectionists, fled.
Massacre at Eridanus secundusEdit
- Main article: Massacre at Eridanus Secundus
On September 12, 2552, Admiral Whitcomb, Fred, John-117, 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. Afterwards the rebels, knowing they couldn't face what was coming alone, set to work on repairing the ships. The two ships are repaired enough that they have some ability to fight back, but a Covenant fleet showed up before repairs could be finished. Whitcomb, feeling it was his duty to warn Earth first and being unable to take on a whole fleet, initiated a Slipspace jump, leaving the helpless rebels behind for the Covenant. Presumably the Covenant destroyed the base and the rebels.
History looks upon this time as an unfortunate (and perhaps inevitable?) misunderstanding between Earth and her colonies, but those fighting for the last decade also realize that it was the most amazing piece of blind fortune the human race has ever stumbled upon. Had we not been armed and learning how to fight in space... what would have happened in the years that followed, when we faced an enemy a hundred times worse? Oblivion, no doubt.
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, ships with Titanium-A armor, advances in ship-to-ship warfare tactics, and above all, the SPARTAN-IIs, all of which would prove crucial in humanity's fight against the Covenant
Though, by and large, the Insurrection was over by the end of the Human-Covenant war, several planets continued to defy the UNSC, either by refusing to return to the UNSC fold or by armed hostility. The colony of Venezia, for example, refused to assist the damaged UNSC Ariadne in its orbit, and opened fire on the UNSC Monte Cassino. Venezia would escalate to be a hub of black market trading and Innies living together with Covenant species. At some point however it seems as though the Insurrection resurged evidence being the actions of the New Colonial Alliance.
Known Star Systems of Insurrection ActivityEdit
- Epsilon Eridani System
- Eridanus system 
- 111 Tauri system
- 23 Librae System
- 26 Draconis system
- Epsilon Indi System
- Charybdis System
- Theta Ursae Majoris System
- Alpha Aurigae System
- The ORION Project is reinitialized by the UNSC to combat rebels.
- A large uprising occurs on the UEG colony of Far Isle. Unable to control the rebellion, the UNSC declares code: Bandersnatch and uses Nuclear Weapons to raze the colony.
- Callisto Incident - A group of insurrectionists board a UNSC Corvette, Callisto and kill the crew. A naval engagement ensues as three UNSC light destroyers are sent to hunt down the captured ship.
- Insurrectionist forces take control of Eridanus II, establishing their own secessionist government in the wake of the coup d'état.
- UNSC forces begin their campaign to retake Eridanus II, deploying a battle group of unknown size to engage the makeshift Insurrectionist defense fleet. Despite the UNSC's best attempts at removing the entrenched rebellion, ONI fails to discover the location of their base. This hollowed-out asteroid would remain a safe haven for Insurrectionists for another three decades.
- Operation: CHARLEMAGNE marks a decisive strike on the Secessionist Union.
- Skirmish at Theta Ursae Majoris - The UNSC Gorgon engages the Bellicose in the Theta Ursae Majoris System. The battle ends in a draw.
- Operation: KALEIDOSCOPE - Jerald Mulkey Ander, the leader of the Secessionist Union on Harvest is assassinated by Avery Johnson.
- Skirmish at Capella - UNSC Gorgon is damaged in a skirmish with Insurrectionist forces, resulting in the deaths of 32 crew members and requiring her to be laid up in space dock for one month for repairs.
- Battle of Theta Ursae Majoris System - Four UNSC destroyers are sent to hunt down the Bellicose, which is reported destroyed in the battle.
- Haven arcology bombing - A terrorist with the Freedom and Liberation Party detonates a commercial nuclear explosive in the Haven arcology on Mamore.
- Operation: TREBUCHET. Fighting breaks out in the Eridanus system first, particularly at Eridanus II and the space around it, as rebels supporting the system's breakaway from the UNSC build a small navy of civilian craft and attempt to take over the system. The disorganized Eridanus Rebels are eventually brought together by Colonel Robert Watts.
- The UNSC responds 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 begins on Eridanus II, as units from the 9th Marine Expeditionary Force are sent to the planet in force, hoping to capture leaders of the 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 SPARTAN-II Program is created by Dr. Halsey and initiated by the UNSC to counter Insurrectionist activity.
- Fighting continues, now in Epsilon Eridani. By this point, the war has taken over a million lives, the majority of which being civilians. A Marine Battalion is posted at the colony world of Tribute, commanded by Lieutenant Colonel Aboim and supported by the corvette UNSC Bum Rush and air support from Hornets. The battalion attempts to put a stop to rebel bomb makers. Two special warfare squads, led by Staff Sergeants Avery Johnson and Nolan Byrne, are involved in disastrous operation in June. Byrne's team is killed during a hostage situation at a Jim Dandy restaurant near Casbah city. Thirty-Eight civilians, three Marines, and two rebels are killed in the bombing. Byrne and Johnson are pulled from the system, and later sent to Harvest.
- Luxury liner National Holiday is destroyed by Insurrectionists above Reach. The Office of Naval Intelligence successfully covered up the bombing as a freak accident.
- Operation: TALON - A team of SPARTAN-IIs are sent to Eridanus secundus to capture Colonel Robert Watts. They succeed in doing so, crippling but not destroying the rebel infrastructure in the Eridanus system. Further plans to attack rebel base apparently abandoned due to Human-Covenant war.
- Shortly afterward, the Spartans were sent to halt a rebellion on Jericho VII.
- Operation: TREBUCHET is abruptly concluded with the start of the Human-Covenant war after the First Battle of Harvest. Though the Insurrection continued for a long time, the rebel threat in the system was rapidly decreased with the threat of the Covenant present. In the meantime, many of the rebels, seeing that the UNSC offered the only real protection against the overwhelming Covenant force, cease to resist, and either submit to the UNSC's control or hide themselves away from both UNSC and Covenant.
- Raid on Camp New Hope: SPARTAN-II Blue Team assaults Camp New Hope on the planet Victoria, recover three stolen nuclear warheads, and eliminate General Howard Graves, a prominent Insurrectionist leader.
- Scyllion Warehouse District Riot: Food riots led by Insurrectionist Jason Kincaide who is smuggling Covenant weapons from The Rubble. Kincaide leads a massive assault upon ONI forces and Jacob Keyes after telling them about the Kestrel, but is killed by Keyes. Riot put down by ODSTs from Midsummer Night.
- Battle of the Rubble: The Rubble, an insurrectionist asteroid habitat, is destroyed, but over a million civilians manage to escape with the help of a UNSC stealth frigate, the Midsummer Night. Also a major UNSC victory against the Covenant.
- Insurrection of Mamore, Spartan-III Alpha Company successfully puts down the rebellion.
- Insurrectionists disable a communications relay on Harmony, and steal two Freighters from a drydock.
- Insurrection activity on Reach continues. In one instance, two insurgents trying to hijack a supply transport are surprised by Noble Team.
- Massacre at Eridanus Secundus: A group of Insurrectionists still hiding in Eridanus secundus are killed by the Covenant after helping a group of UNSC forces. In this case, both the UNSC and the Insurrectionists were united, but the UNSC was forced to abandon them due to a greater threat to Earth.
- Insurrections cause entire planets to go dark and continue smaller operations on Venezia resulting in the destruction of UNSC Ariadne.
