Noble Team is ordered to destroy Sword Base in a torch-and-burn op. During the operation, Noble Team makes their way inside Sword Base where they encounter Dr. Halsey, who asks them to protect her lab. Noble Team is then given direct orders to escort a fragment of Cortana holding crucial data from the Babd Catha Forerunner complex to the Pillar of Autumn. Halsey is then escorted back to CASTLE Base by Jun-A266.

August 30

Cortana has ONI James Ackerson illicitly transferred to the front. This is her revenge for his attempts to eliminate both her and John-117.

Due to the course of the battle on Reach, Operation: RED FLAG is postponed and the Spartan-IIs are prepared for imminent deployment.

The UNSC Pillar of Autumn deploys John-117, Linda-058, and James-005 to Reach Station Gamma to destroy the navigation database of the ONI Prowler, UNSC Circumference, docked in Bay 9, after complications arose for the local AI to implement the Cole Protocol.

First Lieutenant Jake Chapman, along with most of Charlie Company is killed during the Fall of Reach.

The Covenant, despite sustaining heavy losses, wins a crushing victory at the Fall of Reach. Many of the remaining Spartan-IIs are killed.

The surviving Spartan-IIs on Reach are separated into two groups. One recovers Vice Admiral Whitcomb and goes into hiding at Camp Independence. The others are admitted into CASTLE Base by Dr. Halsey and receive parts for the Mjolnir Mark V upgrade and new weapons.

Dr. Halsey learns of Colonel Ackerson's mysterious plans that seem to involve "her" Spartans.

The three surviving members of Noble Team arrive at Aszod; Carter's Pelican becomes too badly damaged to continue carrying them all, so Noble Six and Emile-A239 deploy to the ground.

Battle of Aszod: The Covenant forces throughout Aszod attempt to stop Noble Six and Emile from reaching the Pillar of Autumn , going so far as to deploy Scarab Walkers against them. Carter sacrificially collides his damaged Pelican into a Scarab engaging Emile and Six, destroying it. Emile and Six proceed to push towards the ship breaking yards (now almost totally controlled by the Covenant, who begin making preparations to destroy it) and rendezvous with the scant UNSC forces still attempting to defend the facility. After clearing most of the facility, Six, Emile, and several Trooper squads meet up with Captain Jacob Keyes, successfully delivering the fragment of Cortana. However, Emile is killed by a Sangheili Zealot's Energy Sword.

The Spartan makes a last stand against several Sangheili warriors soon after, during which they met their end. With Spartan-II Red Team currently unrecoverable, the Autumn jumps away from the system, with Cortana using Forerunner navigation data from the Sigma Octanus IV artifact as well as the Babd Catha Forerunner Complex.

September Edit

The planet Coral is reported glassed by the Covenant.

The Battle of New Jerusalem takes place. After a chain of events involving a group of ODSTs attempting to steal gold from a bank vault (Treason),[12] the 26th Marine Expeditionary Force is nearly wiped out, leaving the Rookie as one of few survivors. Eventually, the UNSC forces cut their losses and fall back to Earth.[13]

September 14

Earth's Orbital Defense Platforms are scheduled to come online.[14]

September 19

The UNSC Pillar of Autumn arrives at Alpha Halo. [15]

John-117 is awoken from cryo sleep and tasked with preventing Cortana's capture by the Covenant.

John-117 and Cortana escaped the ship aboard a Bumblebee escape pod, which later crashed on the ring.

The UNSC Pillar of Autumn is forced to crash land on the ring. A significant portion of its crew survives to continue the fight on the ground.

Captain Keyes and the others in his escape pod are captured by the Covenant. Only Keyes escapes summary execution and is taken to CCS-class battlecruiser, the Truth and Reconciliation.

September 20

John-117 leads a Marine force to board the Truth and Reconciliation . They recover Keyes and escape aboard a Spirit Dropship. Keyes orders John-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.

. They recover Keyes and escape aboard a Spirit Dropship. Keyes orders John-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 John-117 to stop Keyes from accessing the 'weapons cache', really a Forerunner research and quarantine facility on the Flood.

John-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 together they 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 with the surviving members.

September 21

The Monitor takes John-117 to the ring's "Library" to retrieve the "Activation Index," a device needed to activate the ring's primary weapon. Having retrieved the Index, the Monitor teleports the Spartan-II back to the Control Room where an irate Cortana confiscates the Index and prevents the ring from firing. John-117 and Cortana flee a now-hostile 343 Guilty Spark and Sentinels.

To forestall the ring from being activated manually, John-117 disables the ring's three Pulse Generators. This is to buy time to destroy the ring by activating the auto-destruct on the UNSC Pillar of Autumn. Only Keyes neural interface can activate the ship's self-destruct, and John-117 embarks once more to rescue the captain.

September 22

September 23

A Time/Date Record Anomaly continues from this point in the narrative, resolved below on Sept 7, 2552.

September's Anomaly Edit

After the recovery of a Forerunner crystal on Reach, the members of an organized resistance comprised of Spartans from Reach and survivors of the Battle of Installation 04 are in some sort of time anomaly, causing them not to be in the "correct timeline."[16] What is known is that the events taken place with the possession of the device take place after September 7.

September 7

The Time/Date Record Anomaly of Sept 23, 2552 most likely rejoins the correct timeline.

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.

Dr. Halsey initiates Operation: WHITE GLOVE, destroying CASTLE Base, thus preventing the Covenant forces above from capturing any UNSC and/or Forerunner technology. Halsey and members of Red Team are protected from the resulting detonation when they hide in the caves of Menachite Mountain beneath the base.

John-117, Cortana, Sgt. Johnson, Lieutenant Haverson, Warrant Officer Polasky, and Corporal Locklear aboard the captured Covenant flagship Ascendent Justice make a slipspace jump to Reach, a temporal anomaly sending them over two weeks into the past, twelve days before the UNSC Pillar of Autumn carrying John-117 would emerge from slipspace at Installation 04.

September 13

UNSC forces aboard the Gettysburg/Ascendant Justice win a crucial victory at the Battle of the Unyielding Hierophant. Grace-093, Lieutenant Haverson of ONI and Vice Admiral Whitcomb are killed. The survivors, now aboard the singular UNSC Gettysburg and with a captured Covenant slipspace drive, depart for Earth to warn of the impending Covenant invasion.

October Edit

Unknown Date

An Edict from the Office of the High Prophet of Truth orders that in the virtue of the Jiralhanae, all Sangheili posted with the Fleet of Profound Solitude, the Fleet of Tranquil Composure, and the Fleet of Inner Knowledge to be completely replaced by Jiralhanae. Each removed Sangheili to be assigned other duties. In celebration, all imprisoned or criminal Jiralhanae were released, rehabilitated, and pardoned. [17]

The UNSC Red Horse is sent to Installation 04's debris field in the Soell System to scout the area for survivors. They detect the prison ship Mona Lisa and deploy Marines into the ship. Soon after, it is revealed that the ship is infested by the Flood and was used by the Office of Naval Intelligence as a laboratory to test the parasite on prisoners. The infestation is contained as the Red Horse unleashes a Shiva-class Nuclear Missile on the Mona Lisa, destroying it.[18]

October 8

Installation 03 is discovered by the freighter Floral Express while fleeing the destruction of Tribute.[19]

October 10[20]

Battle Group Rhino finds twelve unidentified large ships broadcasting outdated civilian IFF codes near Enceladus. Eleven ships immediately jump to slipspace and Rhino engages the remaining ship. UNSC Totem Lake is subsequently lost with all hands and Rhino disengages.

October 20

October 20 through November 2

The Spartan-II Blue Team is deployed to defend Earth during the two weeks that follow the initial Covenant invasion. They participate in numerous combat missions on and around Earth, including Battle of Ross Island in the Antarctica and an underwater operation in the Yucatan Peninsula.

October 21

Sadie Endesha and Mike Branley manage to escape New Mombasa.

The Battle of Mombasa ends with a Covenant victory.

In the dawn, Covenant reinforcements sent by the Prophet of Truth continue arriving at Earth to uncover the Portal.

Alpha-Nine recovers Vergil and escapes from the data facility.

Covenant forces attempt to capture Vergil from the Squad during the Battle of the Waterfront Highway. The Squad manages to hold out and eventually escapes New Mombasa as the city, along with its surroundings are glassed by the Covenant excavation fleet.

October 31

November Edit

November 2

The Battle of Installation 05 begins.

The UNSC In Amber Clad arrives at Installation 05, following the High Prophet of Regret's assault carrier. John-117, aided by ODSTs and Marines, pursue the High Prophet to a Forerunner temple and assassinate him. However, orbital bombardment from the escorting fleets of the newly arrived High Charity destroys the temple. John-117 is thrown into a lake and captured by Gravemind.

November 3

November 3 through November 7

Cortana sends a slipspace message to Earth informing them that John-117 is en route.

The Arbiter reaches the Control Room but is unable to prevent Tartarus from activating the ring. With the help of humans and the Sangheili, 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 standby mode.

November 4

The Sangheili ships holding position around Installation 05 glass the surface of the ring.[19]

November 8

The Prophet of Truth arrives in the Sol system aboard the Forerunner dreadnought, and proceeds on course towards Earth at near-relativistic speeds.[21]

November 8 through November 17

slips in, crashing in Voi. Lieutenant Commander Miranda Keyes orders her troops to fight to the core of the Flood battlecruiser and overload its reactors, destroying the ship and the town and any Flood along with it. The Fleet of Retribution, having followed the Flood infected ship from their blockade at Installation 05 to its arrival at Earth, begins to drop forces to push towards the ship, seeking something that lay within it. It isn't until they come back into Traxus Facility that the Sangheili tell the UNSC that Cortana, the AI formally attached to the Spartan-IIs, the UNSC Pillar of Autumn , and companion of John-117, is supposedly on the downed ship.

, and companion of John-117, is supposedly on the downed ship. The joint UNSC/Separatist force press on to the crash site and eventually break through, fighting past hordes of Flood. With the remaining forces giving cover to John, he enters its Flood created carcass and, with surprise assistance from 343 Guilty Spark, the former Monitor of Installation 04, retrieves what is believed to be Cortana. After the ground forces are evacuated safely the Sangheili begin to glass the immediate area, annihilating the Flood and eliminating any chance of further Flood infection, effectively ending the Battle of Tsavo.

December Edit

The Prophet of Truth was killed in the later months of 2552 along with a sizable Covenant armada, leaving the remaining Covenant forces crippled and leaderless as well as the full destruction of the Gravemind and its Flood forces.

December 11

Battle of Installation 00 Edit

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 could be used to fire all of the Halo installations at once.

After returning to the Sangheili carrier Shadow of Intent with a construct believed to be Cortana, John-117 discovers that it is not Cortana after all, but a looped message from her. It contains vital information nonetheless: the message states that the Gravemind has firmly entrenched itself and the Flood on High Charity but that there is also a way to destroy it without lighting the Halo rings.

with a construct believed to be Cortana, John-117 discovers that it is not Cortana after all, but a looped message from her. It contains vital information nonetheless: the message states that the Gravemind has firmly entrenched itself and the Flood on High Charity but that there is also a way to destroy it without lighting the Halo rings. Despite Lord Hood's urging, Commander Miranda Keyes, along with John-117, Arbiter Thel 'Vadam, Shipmaster Rtas 'Vadum, and 343 Guilty Spark, joined the Separatist Fleet of Retribution through the Slipspace portal to the Ark.

The Separatists on arrival immediately engaged the Loyalist fleet stationed to protect the Prophet while UNSC Forward Unto 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 Sangheili superior tactical skills. 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 John-117 and the Arbiter to the Ark's Cartographer where they pinpointed the Prophet's location. By then Truth had already holed himself in a secure facility near the core of the Ark and had activated a large barrier around the entire core to ward off the attacking forces.

By then Truth had already holed himself in a secure facility near 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, 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 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, John-117 and the Arbiter personally attacked the facility where Truth was to activate the Halo installations.

began its attack on Truth. At the same time the former Covenant city ship arrived from slipspace and crashed on the Ark. Debris, spread from the city-ship, heavily damaged 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, John-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 on the towers, was in fact captured by Truth's forces and was being tortured into pressing the final switch to activate the other Halos, as fail-safes within the structure prevented anyone other than a Forerunner or a Reclaimer to do so. With John-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 thereafter by Truth himself. The Gravemind dispatched Flood forces to assist John-117 and the Arbiter in order to prevent the activation of the Halo Array system; their support enabled John-117 and the Arbiter to reach Truth in time. The Arbiter personally killed Truth with his sword. However, the Gravemind betrayed the two of them after knocking them out of Keyes' Pelican (then piloted by Johnson and also carrying the Commander's body), thwarting their plan of escape and forcing John-117 and the Arbiter to fight their way outside.

Raid on High Charity Edit

343 Guilty Spark, John-117 and the Arbiter learned that the Ark's Forge had created a replacement for the destroyed Installation 04. Realizing that they could use it to fire a tactical pulse which would eliminate the Flood infestation, they decided to light it. 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. John-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.

End of Human-Covenant war Edit

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, John-117 and Sergeant Major Avery Junior Johnson moved in on the Control Room of the incomplete Halo, the latter coming in alone aboard the Forward Unto Dawn. The Dawn was left behind as the only means of escape. By now what was left of the Gravemind had relocated to the new Halo. The Arbiter, Johnson, and John-117, along 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 a few days, but with Flood moving in all around them Johnson explained the necessity of firing the ring immediately, prompting Guilty Spark's protest that activating Halo now would destroy both the Ark and the installation, and Johnson's subsequent reply of, "deal with it," as he prepared to activate the ring. Unwilling to let "his" ring be destroyed again, Spark went rampant, attacking Johnson, John-117, and the Arbiter. However, with the help of mortally-wounded Johnson and his Spartan Laser, John-117 managed to destroy Guilty Spark and start the firing sequence for the new Halo. Just after Johnson's final remarks to John-117, he died. John-117 and the Arbiter then escaped the control room by taking Johnson's Warthog to the Forward Unto Dawn. Due to the unstable, incomplete nature of the ring as it fired, the Slipspace portal collapsed as the Dawn entered it, causing it to be sheared in two. The forward half with the Arbiter made it to Earth, crashing into an ocean (presumably the Indian Ocean). Cortana and John-117 were in the hangar area at the time of the separation, and were thus left in the aft section of the ship, which fell out of Slipstream space at an unknown location, eventually drifting towards Requiem.
