— Sarah Palmer discussing Jul 'Mdama's Covenant presence on Requiem to the SPARTAN-IVs

The Requiem Campaign, also known as the Second Battle of Requiem or the Requiem Conflict, was the second, larger-scale engagement fought on the Forerunner shield world Requiem in February 2558. It was waged between the Prometheans and their Jul 'Mdama's Covenant religious followers and the returning United Nations Space Command.

Background

Main article: Battle of Requiem

Six months before the onset of the battle in July 2557, the Forerunner Promethean supreme commander known as the Didact had been inadvertently awakened from his Cryptum on Requiem and immediately initiated a campaign against humanity, which he saw as unworthy of taking on the Mantle. Revering the Forerunner as a living god, a new "Covenant" faction under the leadership of Jul 'Mdama, allied themselves with the Didact and his mechanical Promethean armies. The Didact was eventually defeated by Spartan John-117 above Earth, leaving the Prometheans without a leader, yet still hostile to humanity. The Prometheans and 'Mdama's Covenant continued to occupy Requiem, which humanity recognized as a site of great value due to the abundance of Forerunner artifacts contained therein, particularly a digital personality impression of the Librarian encountered by the Master Chief during the initial foray on the shield world. As a result, the UNSC Infinity, the most advanced warship in the Navy, was dispatched to establish research facilities on the Forerunner construct and eliminate any opposition from the occupying Promethean and 'Mdama's Covenant forces.

Battle

Infinity's return

In February 2558, the UNSC Infinity returned to Requiem, destroying an Maugen-pattern armored cruiser immediately upon arrival. Strident-class heavy frigates were deployed to protect the ship and establish a position in orbit. SPARTAN-IV fireteams were sent into Requiem to support the Marine, Army, and Air Force assets deployed within the shield world. UNSC forces set up several research bases: Copernicus Base, Galileo Base, and Magma Base. Other locations, such as areas designated "Quarry", "Fortress", and "Sniper Alley", were often contested for control.

During an interception on one of 'Mdama's Covenant archaeological dig sites, Fireteam Crimson discovered one of the three Requiem slipspace artifacts on Requiem in "the Cauldron". The artifact was brought onboard Infinity, where it was examined by Henry Glassman. Glassman, who accidentally activated it, was translocated to Requiem and became a prisoner of 'Mdama's Covenant. There, he was brought to Jul 'Mdama and was forced to find a method to activate the device containing the Librarian AI in "Librarian's Rest". Captain Lasky requested Doctor Catherine Halsey to be brought onboard Infinity to study the artifact. Halsey found out that the artifact was communicating with the ship's system's, notably the engine, and transmitting signal to a location in Requiem. On Requiem, Sangheili terrorist Parg Vol, an associate of 'Mdama, was hunted and eventually assassinated by Fireteam Crimson. During another engagement, a Zanar-pattern light cruiser was destroyed by Infinity Sub-Vessel 3 while it was meeting Crimson who were investigating a Forerunner structure at "Two Giants".

Jul 'Mdama's plan

During their flight to Copernicus Base, Fireteam Castle was shot down by Covenant forces led by Jul 'Mdama. This attack drew Infinity's attention to hunt down 'Mdama. UNSC scientists had discovered that 'Mdama's Covenant were using Requiem's portal systems, and Fireteam Crimson was deployed to assist in the investigation. Incidentally, 'Mdama was detected traversing through the portals, so Fireteam Majestic and Crimson were sent to give chase. After discovering a way to activate Requiem's portal systems, Crimson followed 'Mdama to "the Cauldron", where he purposely left an artifact known as the "Didact's Gift" for Crimson, prompting the team to bring the artifact to Galileo Base.

Fireteam Majestic recovering the "Didact's Gift" from Galileo Base.

Jul 'Mdama's Covenant then staged an attack on the base to show that they were attempting to recover the artifact. While Fireteam Crimson defended the base, Fireteam Majestic extracted "the Didact's Gift" and brought it back to Infinity, where it was analyzed by Halsey. By giving Halsey the "soul of a Promethean Knight", 'Mdama had gained Halsey's interest in cooperating to find the Librarian. Their partnership, however, was discovered by Captain Lasky and Commander Palmer, who then took Halsey into custody. Spartan Gabriel Thorne, during his examination of the artifact, was taken to Requiem like Glassman. On Requiem, 'Mdama's Covenant and Promethean forces attacked UNSC research bases "the Refuge" and Magma Base, but both of these attacks were successfully repelled by Fireteam Crimson with the assistance of Fireteam Shadow in "the Refuge," resulting in the destruction of another cruiser. Additionally, the UNSC gained vital intelligence on Requiem's portal system and was able to control it before Crimson destroyed a device at "the Refuge" that allowed the portals to open in order to limit the movement of 'Mdama's Covenant and Prometheans. During their search for Spartan Gabriel Thorne in the Quarry, members of Crimson were captured by 'Mdama's Covenant forces.

Spartan Thorne was captured by Jul 'Mdama's Covenant and was brought to where Glassman was. Glassman, on the other hand, managed to activate the Librarian's device, and used the opportunity to escape. Glassman's escape distracted the Sangheili who took Thorne prisoner, giving Thorne the chance to retaliate. Together, the duo ran away, heading for Galileo Base, being chased by a vengeful Gek 'Lhar. At the same time, Fireteam Crimson also escaped 'Mdama's Covenant and hijacked a Phantom in the process. Using the captured Phantom, Crimson was able to infiltrate Covenant bases at "Control" and the "Warrens" where they hacked into 'Mdama's Covenant systems and uncovered vital intel on a nearby Covenant supply depo and an archeological dig. Crimson attacked and destroyed the supply depot at "Cyclone," discovering in the process HAVOK nuclear missiles missing their warheads while Fireteam Switchback was sent to disable a Harvester at the archeological dig site. After Switchback disappeared, Crimson was sent to investigate and ensure that the Harvester was permanently disabled. Crimson only found Switchback's blank IFF tags and destroyed two consoles aboard the Harvester to ensure its permanent disabling.

Second attack on the Infinity

Main article: Invasion of the UNSC Infinity

Promethean Knights boarding Infinity

Meanwhile, as Dr. Halsey sat in the brig of the UNSC Infinity, Roland appeared and asked why she attempted to communicate with an unknown intelligence about classified material. After a brief interchange, Halsey used the passphrase override "undid iridium" to gain control of the AI and then use him to move unsuspected to the captain's ready room. Once there she perused all the material she could find for information on the Librarian and Jul 'Mdama, also discovering that John-117 was still alive and had survived the destruction of Installation 00. She then used the terminal to communicate with Jul 'Mdama. She offered her assistance in exchange for what they both wanted: the Librarian's secrets. At that moment, though, Roland regained control of his confused matrices, pulled the plug, and immediately alerted Lasky. Just as the captain was about to have Halsey interred in a cryo tube, alarms sounded across the ship: the Prometheans had gained access to the Infinity and taken all hands by surprise. Most Spartan and Marine fireteams were deployed on Requiem and the Prometheans quickly overran most of the ship. All UNSC assets were recalled to the ship, but at that moment the rest of 'Mdama's Covenant fleet arrived, composed primarily of Zanar-pattern light cruisers, and attacked the Infinity.

At this point, Fireteam Crimson reached the battle, still in the captured Phantom. Infinity's automated point-defense turrets could not differentiate between the thousands of incoming enemy spacecraft and Crimson was hit. Lieutenant Murphy barely guided the out-of-control dropship into one of Infinity's hangars, the bay's vacuum shields decelerating the dropship enough to allow all of its passengers to survive. Fireteam Crimson promptly went to work, clearing the hangar. However, interference from the artifact prevented Roland from closing the bay doors so Crimson was forced to power cycle the Server Room and reboot the ship-wide data link before the hanger bay could be fully secured. At that moment though, teams on board made two discoveries: Jul 'Mdama's Covenant had internally disabled the all port defenses, leaving Infinity open to attacks from 'Mdama's Covenant fleet, and that 'Mdama's Covenant had stolen UNSC HAVOK tactical nuclear weapons and had armed the warheads in the Server Room and the Engine Room. Despite 'Mdama's Covenant protecting the warheads with active camouflage, Fireteam Crimson, managed to disarm all seven and secure both rooms. With the nukes disarmed and back in UNSC control, Crimson reactivated the ship's port defenses, which promptly destroyed all adjacent ships, including at least one light cruiser. The remainder of 'Mdama's Covenant fleet fled as the UNSC regrouped and repelled the remaining boarders. But the Infinity was not safe yet. As Lasky escorted Halsey to the bridge, it was brought to his attention that Infinity was unable to move from its current spot because it was trapped by a sort of Slipspace anchor. As he turned his back, a Promethean Knight appeared, knocked Commander Palmer to the deck, grabbed Dr. Halsey, and disappeared again.

Fireteam Majestic arrive in time to save Thorne and Glassman.

As the massive battle waged hundreds of miles over their heads, Spartan Thorne and Dr. Glassman trekked through the dusty canyons near "Sniper Alley" to reach Galileo Base. Glassman sat down to take a rest and Thorne stopped to glance around. Realizing that something was amiss, he told Glassman to get to safety just as Gek 'Lhar emerged from invisibility, swinging his energy sword and slicing Thorne's Storm Rifle in half. Gek tossed Glassman aside like a ragdoll and attempted to truncate Thorne, who disarmed him in the process. Thorne managed to knock the Elite assassin to the ground. The Spartan then tried to break Gek's skull with a boulder, but the Elite caught it, flipped Thorne to the ground and brought the stone down on his chest and head, stunning him. Glassman was attempting to reach the fallen energy sword, but was stopped when Gek stepped on his outstretched arm, breaking it. Just as the Elite was preparing to execute the downed Spartan, he was shot in the head three times by DeMarco, who had shown up with the rest of Majestic. The Spartans looted his body, taking Gek's energy sword and active camouflage module before Madsen located a map of Requiem.

Disrupting Covenant Operations

Following the end of the attack on the UNSC Infinity, the human forces were redeployed to continue disrupting 'Mdama's Covenant operations on the planet. Having been interrupted in their mission to deactivate the portals at "Apex" and capture the site by the attack on the Infinity, Fireteam Crimson were sent back to "Apex" to complete their original mission and secure the area. Crimson succeeded in closing the portals and Infinity sent Fireteam Lancer to hold "Apex". In addition, Spartan Jared Miller picked up an SOS coming over 'Mdama's Covenant frequencies in Morse code. Getting a distress call from Fireteam Majestic, Crimson and Fireteam Kodiak were sent to "Cyclone" to take down three Covenant plasma artilleries stationed there that Majestic was under fire from. During the mission, 'Mdama's Covenant displayed an inexplicable ability to predict the UNSC's movements.

With Fireteam Lancer having discovered a nest occupied by Jul 'Mdama's Covenant in the "Warrens" near "Apex," Crimson was sent to aid Lancer in taking out the Covenant position. Fighting through 'Mdama's Covenant base, the SOS was detected again and Crimson followed it to the imprisoned Fireteam Switchback who had mysteriously vanished while disrupting one of 'Mdama's Covenant dig sites. Crimson and Lancer rescued Switchback while elsewhere Poker Squad captured a wounded Sangheili who offered up the location of one of 'Mdama's Covenant listening posts in exchange for his own life. After extracting Crimson and Switchback, Sarah Palmer ordered Crimson redeployed to destroy the listening post. Crimson returned to "Lockup" where the Sangheili revealed 'Mdama's Covenant listening post was. Fighting their way through 'Mdama's Covenant forces stationed there, Crimson discovered a captured Army Pelican that had been shot down in "the Cauldron" and thought destroyed. 'Mdama's Covenant were able to tap into the Pelican's communications systems and use them to spy on UNSC comm traffic, explaining their inexplicable ability to predict the UNSC's movements. Crimson deactivated the energy tethers hooked into the Pelican's communications systems and Robert Dalton conducted an orbital strike on the Pelican, destroying it and permanently depriving the Covenant of their ability to spy on the Infinity's communications with her forces.

Believing that the map Anthony Madsen had recovered from Gek 'Lhar could hold the key to freeing Infinity from Requiem, Dr. Henry Glassman had Crimson redeployed to "Control" to test his ability to read the map. Glassman guided the fireteam in activating Forerunner heavy weapon caches, beam turrets and anti-aircraft guns. With the help of the activated defenses, Crimson destroyed several Phantoms and wiped out 'Mdama's Covenant forces in the area, proving Glassman's interpretation of the map to be correct. Shortly thereafter, Glassman, still on Requiem with Fireteam Majestic, was extracted back to Infinity by a Pelican.

The Janus Key and Halsey

Dr. Catherine Halsey meets the Librarian in the shrine at "Librarian's Rest".

With the abduction of Dr. Catherine Halsey by enemy forces, Admiral Serin Osman, head of the Office of Naval Intelligence, ordered Lasky to assassinate the doctor before 'Mdama's Covenant could glean any sensitive intel from her. Sarah Palmer was deployed from Infinity despite Lasky's admonishments to the contrary. As soon as she was out of earshot, Lasky contacted Fireteam Majestic and asked them to rescue Dr. Halsey without telling them that Palmer was en route. The Spartans returned to 'Mdama's Covenant's base and engaged the sentries outside while Thorne used his recently-acquired cloaking unit to slip inside. At the same time, Dr. Halsey unlocked the shield set up by Glassman and entered the Librarian's shrine. Inside she was greeted by the Librarian's imprint, which presented to her the two pieces of the Janus Key, an artifact that would reveal the location of every piece of Forerunner technology in the galaxy. Once she reappeared outside the shrine, Jul 'Mdama snatched one of the halves away from her, not noticing the second piece in Halsey's hand. At that moment Thorne broke a nearby sentry's back, killing the other with his assault rifle. Halsey tossed the other half of the Janus Key to Thorne. Just as a sword-wielding warrior was about to kill him from behind, it was felled by Palmer. A pair of Promethean Knights appeared to protect 'Mdama and Halsey, but not before Palmer shot the doctor in the left shoulder. The rest of Majestic appeared and fought through the army of Prometheans alongside Palmer. Before they could reach the cornered 'Mdama, a Knight appeared and teleported away with him and the injured doctor.

Following Halsey's abduction, Infinity dispatched all fireteams from both Infinity itself and three Vindication-class light battleships to search for her. Fireteam Crimson was dispatched to "Cyclone" where Halsey had been routing communications through the area before she was snatched. With the help of beam turrets and Aggressor Sentinels under the Librarian's control, Crimson was able to access 'Mdama's Covenant data terminal with the Librarian aiding Roland and Dr. Lani Truman with the decryption as she prepared to transmit herself to the Absolute Record. Both the decryption and transmission became stalled at 99%, resulting in Crimson opening the breaker on the power source in the area. The Librarian's imprint was broadcast to the Absolute Record in the form of a massive data stream while Halsey's signal was determined to have bounced to "Control". At "Control", where Boa Squad had been wiped out by 'Mdama's Covenant, Crimson fought off the occupying forces and activated the comm terminals in the area. 'Mdama's Covenant received backup in the form of Prometheans, but Crimson was able to hold them off long enough for Roland to determine that the signal next bounced to "Apex". Once Crimson got to a safe location, Robert Dalton commenced an aerial bombardment of "Control," wiping out the remaining Promethean forces. At "Apex," Crimson discovered the area protected by multiple Covenant shields and heavily fortified by infantry troops supported by Phantoms. Using Scorpion tanks, Crimson fought through the occupying forces of 'Mdama's Covenant and Prometheans, allowing Roland to determine the signal next bounced to "Lockup".

When Crimson arrived at "Lockup," they faced off against Jul 'Mdama's fierce resistance including Ghosts, Wraiths and Hunters. Following the signal being emanated by IFF tags, Crimson fell into 'Mdama's Covenant trap, but managed to fight their way out of it. Crimson succeeded in clearing the area, but 'Mdama's Covenant and Prometheans sent further reinforcements to "Lockup". Crimson managed to eliminate the initial waves of Prometheans and assist Poker Squad in fighting off more attackers. With Poker Squad safe, Crimson was sent to find Hawk Squad whose IFF tags were detected nearby. The signal eventually lead Crimson to a gravity lift the UNSC was never able to activate before leading to the roof of the main structure. On the roof, Hawk Squad's IFF tags were found, revealing that they were being used by 'Mdama's Covenant forces as Reclaimers in an attempt to activate a Forerunner device. After they couldn't activate it, the Sangheili killed them in frustration. With the device being where Halsey's signal ended up before bouncing off into 'Mdama's Covenant battlenet, Crimson activated the device while fighting off more of 'Mdama's Covenant and Promethean forces. The Forerunner device proved to be a large map of Requiem which, combined with the map recovered from Gek 'Lhar, was believed by Roland to possibly be the key to freeing Infinity from Requiem. With the search for Halsey having reached a dead end, Crimson was extracted from the area.

Requiem's end

Requiem and it's sun are destroyed in the conclusion of the battle.

Believing to have obtained what they were looking for, Jul 'Mdama activated Requiem's self-destruct system which set the shield world to collide with its sun. All of 'Mdama's Covenant ships were ordered to evacuate from Requiem; the crew of Infinity took note of this mass exodus and soon realized that Requiem was steadily moving towards the system's star. Infinity could not move, being still firmly anchored to the shield world due to the anchor generated by the slipspace artifact on board resulting in the ship getting pulled along with Requiem towards the sun. Using the map obtained by Fireteam Majestic from Gek 'Lhar, Dr. Henry Glassman was able to determine that there were three artifacts generating the anchor and that deactivating the two located on Requiem would set the ship free. Commander Sarah Palmer decided to take Fireteam Majestic after one artifact while sending Fireteam Crimson after the other. As Requiem got closer to its sun, the planet began experiencing frequent earthquakes from the gravitational disturbance created by the sun causing the shield world to begin shaking itself apart.

Following the coordinates from the map, Crimson was redeployed to the area where they had previously stopped 'Mdama's Covenant archeological dig. Eliminating 'Mdama's Covenant forces around the area, Crimson discovered that the coordinates pointed to inside of a rock wall and realized that the excavation they had interrupted was to find the artifact. With the artifact beyond their reach, Spartan Jared Miller decided to reactivate the disabled Harvester and use its plasma drill to bore a hole through the rock. However, Covenant drop pods deployed more troops while the Harvester, which had been retaken by 'Mdama's Covenant, had an energy shield protecting its entrance. While Crimson required air support to blast through the shield, anti-air defenses in the area prevented that. Though the weapons were shielded, Roland managed to take down the shields, allowing Crimson to destroy the guns. Lieutenant TJ Murphy was able to take out the shield with a Pelican's guns and Crimson were able to board the Harvester, eliminate the crew and rescue several scientists who had been kidnapped by 'Mdama's Covenant to repair the Harvester. However, Dr. Dennis Russell revealed that the Harvester's power supply had been destroyed and the Harvester was inoperable. Roland was able to come up with a plan to retrieve a replacement power supply for the Harvester and had Crimson extracted.

On Roland's direction, Crimson was sent back to "Apex" to get the power supply, but due to the anti-air defenses being too heavy, Crimson was instead dropped in the "Warrens" to make their way to "Apex" through an alternate route. Outside the main cavern, Crimson was aided by an orbital bombardment sent in by Robert Dalton. Battling 'Mdama's Covenant and Promethean forces, Crimson was forced to activate three energy sources in the "Warrens" to overload a locked door, but managed to make it to "Apex". In "Apex," Crimson met up with Fireteam Forest whose Pelican had been shot down in the area and the two fireteams combined forces, using Warthogs to push up "Apex" towards a structure indicated by Roland. After taking down the shield generators blocking off the structure and eliminating 'Mdama's Covenant and Promethean forces, Crimson activated a Covenant comm terminal which set off an alarm that drew a Lich to the area. Roland revealed his plan to be to steal the Lich's engine core to replace the Harvester's power supply. Crimson and Forest managed to eliminate all the forces dropped by the Lich which eventually retreated to a cliffside to pepper the area with turret fire. Crimson managed to board the Lich and steal the power supply, destroying the Lich in the process. With the area still too dangerous for Pelican evac, Crimson retreated to the "Warrens" using the available vehicles in the area to escape the same way they came in. In the "Warrens," with the quakes getting worse, Crimson was forced to contend with 'Mdama's Covenant and Promethean forces, aided by Mantises from crashed Pelicans. With the "Apex" guns active and preventing a Pelican extraction as well as an energy shield blocking the way out, Crimson destroyed the three energy sources they had activated on their previous trip through the area, disabling the shields and guns. After eliminating 'Mdama's Covenant forces on the beach outside, including Wraiths, Crimson was extracted to finish their mission to shut down the artifact.

Returning to the artifact site, Crimson battled their way back onto the Harvester which had once again been retaken by Jul 'Mdama's Covenant. By this point, Requiem was starting to fall apart with pieces of the outer shell crashing to the inner surface and Infinity had evacuated all forces but Fireteam Crimson and Fireteam Majestic. After eliminating the minimal crew, Crimson used the Lich's stolen power supply to restore power to the Harvester. Using the Harvester's plasma drill, Crimson bored a hole through the rock wall into the cavern system beyond where the artifact they were after was located in a hidden Forerunner structure. Fighting through defending Promethean forces, Crimson was finally able to enter the structure and deactivate the artifact. As Requiem grew dangerously close to the sun, localized gravity fluctuations started affecting the shield world's surface. Near the exit, Crimson encountered some religiously devoted Sangheili who were determined to reactivate the artifact. Crimson eliminated the Sangheili and were extracted by Murphy's Pelican outside to a make an escape from the falling apart planet.

At the same time Crimson was fighting to deactivate their artifact, Palmer and Fireteam Majestic fought to reach and deactivate the other one. By the time Crimson's artifact was deactivated, the Spartans had managed to reach the structure containing the remaining artifact, but faced determined 'Mdama's Covenant forces who continued to try to prevent them from freeing Infinity despite being left behind to die with Requiem. Palmer and Majestic managed to eliminate the remaining enemy forces and Gabriel Thorne deactivated the artifact. On Infinity, the third artifact rose from where it had been stuck to the floor, showing its deactivation and Lieutenant James discovered that the ship was now free to move once more. After Crimson and Majestic's Pelicans made a rough but safe landing, Infinity quickly fled Requiem and jettisoned the artifact into the sun. Requiem was consumed by the sun which then went supernova. Infinity made an emergency slipspace jump to avoid the supernova, followed through the jump by some of the sun's plasma. Though injuries were reported on all decks when the ship exited slipspace, the crew suffered no major casualties and celebrated their successful escape.

Aftermath

"Not only would Requiem and the important history it possessed be lost forever, but many Spartans would sacrifice their lives during the occupation."

— Curator on the Requiem Campaign

With one half of the Janus Key in possession of each belligerent, the artifact remained divided and could thus not be used for its intended purpose. Aboard Infinity, Lasky and Palmer joined Dr. Glassman as he studied one half of the Key. Meanwhile, Dr. Halsey—now missing her left arm—seemingly agreed to collaborate with Jul 'Mdama, claiming that she wanted revenge.
