  • The Time/Date Record Anomaly of Sept 23, 2552 most likely rejoins the timeline here.
  • Dr. Halsey and members of Red Team discover an enigmatic shard in a Forerunner installation below CASTLE Base. They are besieged by Covenant forces who seek to possess the shard.

September 2552

The remaining Spartans, Admiral Whitcomb, Dr. Halsey, Sgt.

September 19, 2552

September 20, 2552

  • SPARTAN-117 leads a Marine force to board the Truth and Reconciliation. They recover Keyes and escape aboard a Covenant dropship. Keyes orders SPARTAN-117 to find the "Silent Cartographer", a map room that will reveal the location of the Control Room. Keyes leaves to lead an assault on a Covenant weapons cache.
  • Having found the map room and the pertinent information, Cortana directs a Pelican to take them to the area where the ring's Control Room is. Upon reaching the Control Room, Cortana transfers to the Control Room's computer and directs SPARTAN-117 to stop Keyes from accessing the 'weapons cache', really a Forerunner quarantine facility.
  • SPARTAN-117, without Cortana, enters the facility but is unable to locate Keyes. Instead, he discovers the "Flood" and is forced to retreat. He links up with marines and takes command of the surviving members of Keyes' team and fight their way to the extraction point. However, the Spartan is conscripted by the "Monitor of Installation 04" and teleported away before he can be evacuated the surviving members.

September 21, 2552

  • The Monitor takes SPARTAN-117 to the ring's "Library" to retrieve the "Index", a device needed to activate the ring's primary weapon. Having retrieved the Index, the Monitor teleports the Spartan back to the Control Room where an irate Cortana confiscates the Index and prevents the ring from firing. SPARTAN-117 and Cortana flee a now-hostile 343 Guilty Spark and Sentinels.
  • To forestall the ring from being activated manually, SPARTAN-117 disables the ring's three Pulse Generator. This is to buy time to destroy the ring by activating the auto-destruct on the Pillar of Autumn. Only Keyes neural interface can activate the ship's self-destruct, and SPARTAN-117 embarks once more to rescue the captain.
  • Cortana teleports the Spartan to the Flood-overrun Covenant cruiser where Keyes is being held. Alas, the pair arrives too late to save Keyes, who has been merged into a Brain Form. SPARTAN-117 retrieves the neural interface by punching in the former-captain's head. Cortana downloads the necessary codes, and the duo returns to the Pillar of Autumn on a captured Banshee.
  • 343 Guilty Spark overrides the auto-destruct codes, forcing SPARTAN-117 to manually destabilize the ship's still-functioning fusion cores. SPARTAN-117 and Cortana then escape the resulting explosion and the fragmentation of the ring aboard a Longsword.
  • Sergeant Johnson, Lieutenant Haverson, Warrant Officer Polaski, Corporal Locklear also escape the destruction of the ring aboard a Pelican.
  • The Battle of Installation 04 ends. Gunnery Sergeant Stacker, Survives but is unknown how he does.

SPARTAN-117 and Cortana rendezvous with Johnson's group in Installation 04's debris field. They also recover a set of cryotubes, one which contains SPARTAN-058.

September 23, 2552

  • As the Longsword and Pelican are not jump capable, the UNSC survivors assault and capture the Ascendant Justice, a Covenent warship and apparently the flagship of the covenant fleet sent to Instalation 04, They then set course for Reach.
  • A Time/Date Record Anomaly continues from this point in the narrative, resolved above on Sep 7, 2552.

October 20, 2552

  • The High Prophet of Regret's assault carrier breaks through the orbital defenses and initiates a ground assault on New Mombasa and the surrounding area.
  • SPARTAN-117 deploys to New Mombasa in an attempt to capture the High Prophet of Regret. Before this can happen, the assault carrier initiates a slipspace jump within the city, escaping Earth and destroying the city in the process. The UNSC In Amber Clad, with SPARTAN-117 aboard, successfully pursues the carrier through slipspace.
  • The First Battle of Earth ends.

October 21, 2552

October 22, 2552

  • Gravemind sends SPARTAN-117 and the Arbiter to secure the Index and prevent the installation from being activated. SPARTAN-117 is teleported to High Charity while the Arbiter is teleported close to the Control Room. Both are aided by the chaos of the Covenant civil war.
  • SPARTAN-117 is unable to prevent the Index from leaving High Charity with Tarturus. Instead, on the advice of Cortana, the Spartan stows away aboard the Forerunner ship that is carrying the High Prophet of Truth to Earth. Cortana remains behind to ensure the destruction of Installation 05, should that become necessary.
  • Cortana sends a slipspace message to Earth informing them that SPARTAN-117 is on route.
  • The Arbiter reaches the Control Room but is unable to prevent Tarturus from activating the ring. With the help of humans and the Elites the Arbiter kills Tarturus. This allows Commander Keyes to physically remove the Index from the Core, temporarily interrupting the firing sequence.
  • Due to the interruption, Installation 05 automatically sends a signal to all other Forerunner installations in the galaxy, activating and placing them in stand-by mode.

October 31, 2552

  • Battlegroup Stalingrad arrives to retrieve the survivors, but is unsuccessful due to the Covenant presence. Despite superior tactical skill, the UNSC battlegroup is destroyed.
  • Halsey and the other survivors hold off pursuing Covenant troops long enough to flee to the safety of the Shield World and seal the entrance.
  • Sentinels annihilate the remaining Covenant forces as Onyx 'disintegrates'.
  • Kurt dies after destroying Onyx by detonation of 2 FENRIS warheads.
  • The Battle of Onyx ends.

Late November/December

The tail end of 2552 saw the bloodiest period of the Great War and the beginning of the end. The Prophet of Truth was killed in the later months along with a sizable covenant armada, leaving the Covenant forces crippled and leaderless as well as the full destruction of Gravemind and it's Flood forces.

Second Battle of Earth

Main article: Second Battle of Earth

At the beginning of the year, Covenant Loyalist forces assaulted the Human city of Cleveland, Ohio in the United States on Earth. The Loyalists were looking for the Key of Osanalan, a mysterious Forerunner device related to the Halo Installations.

Later during the Second Battle of Earth, a battle at Pawas in Afghanistan took place. There, UNSC Marine Corps forces battled Loyalist forces for control of a Satellite installation. Numerous Marines of the 2nd ODST Battalion targeted the Forerunner Dreadnought entering Earth's atmosphere. Onboard was one of the last SPARTAN-II Commandos, Master Chief Petty Officer John-117.

Battle for Kenya

Main article: Battle of the Crow's Nest

During the Battle for Earth, the Crow's Nest was an Underground Facility used by the UNSC Defense Force to coordinate local Army, Navy, and Marine forces.

Shortly after John-117's arrival in Kenya, Loyalist forces attacked the facility in force, supported by a CCS-class Battlecruiser orbiting above the savannah.

SPARTAN-117, SgtMaj Avery Johnson, the Arbiter, GySgt Pete Stacker, and GySgt Reynolds then organized a defense of the base. First, they attacked infantry in a large roadway containing numerous supply trucks and armament. Then, they engaged one of the bases hangars in control by Jiralhanae forces, with support by Type-52 "Phantom" Troop Carriers. When they took control of that hangar, it allowed Marines to escape from the base.

Soon after the short skirmishes, they detonated a large bomb in the Operations Center, effectively destroying the base and all enemy forces within it.

Main article: Battle of Voi

The Battle of Voi was the last battle in the long and bloody Second Battle of Earth.

The Prophet of Truth's fleet of twenty-odd CCS-class Battlecruisers and two Assault Carriers led by Truth in the Forerunner Dreadnought had committed all their forces to Africa, specifically Voi, Kenya and the surrounding regions.

At Kenya, Brute-led Covenant infantry and vehicular detachments overwhelmed ground-based UNSC defending forces while Truth's cruisers deployed to Voi, glassing a savannah in pursuit of a presumed Forerunner artifact hidden underground there, presumed to be the Ark.

SPARTAN-117 led a UNSC counterattack to regain lost UNSC ground, retaking a jungle near Mount Kilimanjaro and securing the area around the Crow's Nest. Commander Miranda Keyes and Sergeant Major Avery J. Johnson then organized a small UNSC strike force led by SPARTAN-117 to attack the Covenant Loyalist-held Tsavo Highway, and thus have a platform for a strike at Voi.

The UNSC Marine Corps was able to retake the Tsavo Highway, and it served for a staging ground for the battalion that would retake Voi. The UNSC forces stationed already at Voi had already suffered severe casualties, with only pockets of Marines drawn in a scattered last defense against numerically superior and vehicularly-supported Loyalist forces.

Fleet Admiral Sir Terrence Hood declared that it was imperative that SPARTAN-117's attack force retake Voi. Lord Hood's plan was that he would launch a low-level aerial strike on Truth's fleet above the Forerunner artifact, and prevent him from activating the presumed Ark. However, a Loyalist anti-aircraft emplacement stationed at Voi prevented Hood fleet from advancing; SPARTAN-117 was to retake Voi and destroy the anti-aircraft emplacement to allow Hood to attack Truth's fleet, and prevent him from activating the Ark.

They later defeated the AA guns, opening up a pocket in the Loyalist Defenses for the Home Fleet to come in and engage Truth's forces. They were successful in damaging the Dreadnought, though it was allowed to escape through the Portal.

Flood on Earth

The victorious UNSC forces were now encountering unknown hostiles all over the Town and the splintered and weary forces were no match. The Flood had found their way to Earth and begun to infect and spread.

Commander Keyes gave a single order, which was to fight to the core of the ship and overload its reactors, destroying the ship and the town and any Flood along with it.

The Sangheili Fleet of Retribution, had followed the Flood infected ship from their blockade at Installation 05 to its arrival at Earth. They began to drop forces to push towards the ship, seeking a prize that lay within it. It wasn't until they came back into Traxus Facility that the Sangheili told the UNSC. Cortana, the AI formally attached to the Spartan-IIs, the UNSC Pillar of Autumn and companion of John-117 was upon that downed ship.

The joint UNSC/Separatist force pressed on, still giving their all to getting to the crash site. They eventually broke through, fighting past Flood Pure Forms. With the remaining forces giving cover to the Chief, he entered its Floodformed carcass and retrieved Cortana. After the ground forces were evacuated safely the Elites began to glass the immediate area, annihilating any chance of further Flood infection, effectively ending the Battle of Voi.

Battle of Installation 00

Main article: Battle of Installation 00

The Prophet of Truth, having successfully activated the artifact in Kenya, left Earth through a Slipspace portal to the Ark, a Forerunner structure that can be used to fire all of the Halo installations at once.

Despite Lord Hood's urging, Commander Keyes took ships from the Home Fleet with a small fleet of Separatist cruisers lead by the carrier Shadow of Intent and proceeded through the Slipspace portal and arrived at the Ark.

The Separatists on arrival immediately engaged the Loyalist fleet stationed to protect the Prophet while the Dawn deployed Marine Shock Troopers to locate Truth. Despite being outnumbered 3-to-1 in space, the Separatist fleet made short work of the Loyalist space forces, likely due to the Elites' superior tactical skills or their weapons being upgraded by humans. The Covenant Loyalist Fleet had been destroyed and the only Loyalists left alive were Truth and his forces on the Ark. 343 Guilty Spark, now working with the UNSC-Separatist Alliance, led SPARTAN-117 and the Arbiter to the Ark's Cartographer where they pinpoint the Prophet's location. By then Truth had already holed himself in a secure facility in the core of the Ark and had activated a large barrier around the entire core to ward off the attacking forces.

The UNSC ground forces, along with Separatist reinforcements, assaulted three emitter pylons that powered a small section of the barrier. When the defending forces were eliminated and the pylons shut down, the Shadow of Intent began its attack on Truth. At the same time the former Covenant city ship High Charity arrived from Slipspace and crashed on the Ark. Debris spread from the city ship heavily damaged the Shadow of Intent and helped spread a new Flood infestation on the Ark as a means to stop Truth and to be safe from the Halo activation array. Without any heavy support, SPARTAN-117 and the Arbiter personally attacked the facility where Truth was to activate the Halo installations.

Sergeant Major Johnson, who had disappeared during the assault, was in fact captured by Truth's forces and was being tortured into pressing the final switch to activate the other Halos. With SPARTAN-117 and the Arbiter too far away to stop Truth, Commander Keyes grabbed a Pelican dropship and crashed into the facility to rescue Johnson, but was killed soon after by Truth himself. The Gravemind dispatched Flood forces to assist SPARTAN-117 and the Arbiter in preventing the Halos' activation and the Arbiter personally killed Truth. However, the Gravemind betrayed them and while Johnson managed to escape with Commander Keyes' body in the Pelican, SPARTAN-117 and the Arbiter had to fight their way outside.

Elimination of the Flood

Main article: Second Battle of High Charity

343 Guilty Spark had managed to facilitate the making of a new Halo through the Ark, explaining that a tactical pulse from it would eliminate the Flood infestation. However, this new Halo lacked an Activation Index. The only way they could get another Index was to rescue Cortana from High Charity since she still possessed the Index from Installation 04. Through a tough battle, SPARTAN-117 and the Arbiter successfully entered the ruins of High Charity and recovered Cortana, using a partly-damaged Pelican to escape while High Charity was destroyed as its reactors went critical after the Spartan blasted them.

End of the War

With the Index secure, the Arbiter ordered that the remaining UNSC forces relocate to the Separatist ships and escape back through the Slipspace portal to Earth while he, SPARTAN-117 and Sergeant Major Johnson moved in on the Control Room of the incomplete Halo. The Dawn was left behind for them to use to escape. By now what was left of the Gravemind had relocated to the new Halo. The three heroes with 343 Guilty Spark made it through waves of Flood to the Control Room. 343 Guilty Spark explained that the new Halo would be ready to fire within days, but with Flood moving in all around them Johnson wanted to fire the ring now. When Guilty Spark protested that activating Halo now would destroy both the Ark and the installation, Johnson told him to "deal with it" and prepared to activate the ring.

Unwilling to let "his" ring be destroyed again, Spark went rampant, killing Johnson and attacking SPARTAN-117 and the Arbiter. However, by the help of a dying Johnson and his laser, SPARTAN-117 managed to destroy Guilty Spark and start the firing sequence for the new Halo. They escaped the control room by taking Johnson's Warthog to the Forward Unto Dawn.

However, the Slipspace portal collapsed as the Dawn entered it and while the forward half with the Arbiter made it to Earth, the rear half fell out of Slipspace with Cortana and SPARTAN-117 becoming missing in action.
