The '''Raid on Installation 04B''' was a small engagement between the [[United Nations Space Command|UNSC]]-[[Fleet of Retribution|Sangheili]] alliance, [[the Flood]] and later the [[Forerunner]] [[Sentinel]]s acting under [[343 Guilty Spark]]'s orders. It took place immediately after the [[Raid on High Charity|raid]] on [[High Charity]] and marked the end of both the [[Battle of Installation 00]] and the [[Human-Covenant War]].<ref>'''[[Halo 3]]''', campaign level ''[[Halo (Halo 3 level)|Halo]]''</ref>

After realizing that the [[Prophet of Truth]] had gained access to the Ark, a joint UNSC-Sangheili attack force was sent through the [[Portal at Voi]] to combat the Prophet of Truth's Covenant force there, and stop the Covenant form activating the [[Halo Array]] and destroying all sentient life in the galaxy.

John-117 landed in High Charity and combated Flood forces deep into their hive. After fighting through waves of Flood forms, he retrieved Cortana, and therefore, the activation index she acquired during the events of the original [[Battle of Installation 04]]. The SPARTAN then set High Charity's secondary reactors to explode. He met up with [[Thel 'Vadam]], who had also ventured into the hive to help him, and they took off in a [[D77H-TCI Pelican|Pelican]] to activate Installation 04B and destroy the [[Flood]]. As they left, ''High Charity exploded'', killing nearly all of the Flood there. Meanwhile, the human and Sangheili survivors from Installation 00 were evacuated to the [[CAS-class assault carrier|assault carrier]] ''[[Shadow of Intent]]'' which headed back to Earth through the portal.

John-117 crash-landed the damaged Pelican near the Installation's [[control room]]. At the same time, [[Avery Junior Johnson|Sergeant Major Avery Johnson]] landed the {{UNSCShip|Forward Unto Dawn}} on the Installation, far away from the control room. On foot, John, along with Cortana and Thel 'Vadam, made their way to the control room. The [[Gravemind]], having survived ''High Charity'''s explosion, sent waves of [[Flood dispersal pod]]s to prevent the activation of the Installation. The SPARTAN and the Arbiter fought through the Flood forces as they progressed to the top of the tower, with some assistance from the [[Sentinel]]s and Sergeant Johnson. Once at the top, the team met up with the sergeant, secured the area and entered the control room.

Once inside, the team hesitantly tried to activate the Installation immediately. [[343 Guilty Spark]], after realizing that firing the partially-completed Installation would destroy the megastructure as well as the Ark, turned against the team. His initial attack mortally wounded the sergeant and blasted the former Arbiter out of the control room. John-117 was severely injured by the initial blast to the point of draining his shield. The SPARTAN was locked into a battle with the rampant Monitor and struggled to destroy it. The mortally wounded Sergeant Johnson took the rogue Monitor by surprise with his [[M6 Grindell/Galilean Nonlinear Rifle|Spartan Laser]], temporarily incapacitated the Forerunner construct. John, seizing the moment, used the sergeant's Spartan Laser to destroy Guilty Spark. John tended to the grievously wounded Johnson, whose dying words were  ''"send me out, with a bang."'' Cortana gave her condolences to John, briefly mourning the death of his friend, before firing the Installation using the Activation Index.

As the remaining members of the team exited the control room, they found themselves fighting against both Sentinels and the Flood. During the battle, the team were addressed telepathically by the Gravemind, who warned them that their efforts would only delay the Flood's ultimate goal of consuming the galaxy. The team made their way out of the vicinity of the tower and commandeered an abandoned [[Warthog]] left behind by Sergeant Johnson. With the vehicle, the team rode to the ''Forward Unto Dawn'' as fast as they could, passing through a labyrinth of construction tunnels, and collapsing platforms. The team eventually made it to the ''Dawn'' by crash-landing into the ship's cargo bay. Thel quickly climbed to the bridge and started piloting the ship to safety, while John struggled to hold on in the cargo bay of the vessel. As they approached the Portal, the incomplete Installation fired, causing it to explode and severely damage the Ark. Master Chief John-117, Cortana, and Arbiter Thel 'Vadam had escaped.

This battle apparently marked the end of the Flood threat. As the incomplete Installation 04B fired, it obliterated itself, along with presumably all Flood and Sentinel forces, as well as any surviving Covenant forces on it or the Ark, which being directly below the installation, was severely damaged.<ref name="Array"/>

While ''Forward Unto Dawn'' was entering the Portal the field collapsed, severing the ship in two. The bow, with Thel inside, made it to the exit coordinates above Earth and crashed into the Indian Ocean. The stern section was less fortunate, being thrown out of the collapsing slipspace field on the way. John and Cortana were trapped in the wreckage as it drifted in space for several years, eventually being caught in the gravity of [[Requiem]], a Forerunner [[shield world]], in [[2557]]. This led to a series of [[Battle of Requiem|series of skirmishes]] as the Master Chief and Cortana struggled to find a way back to human space, opposed by a [[Jul 'Mdama's Covenant|reformed Covenant faction]] which had sought out Requiem and the [[Ur-Didact]]'s [[Promethean#Mechancical_Prometheans|Promethean]] forces within the shield world.<ref>'''Halo 4'''</ref>

Some time after the battle, the UNSC dispatched a number of scouting groups to the wreckage of the Ark. While it was originally assumed that 343 Guilty Spark was destroyed by John-117, it was later found that he survived his damages, albeit in an irreversibly damaged state. He sent a distress signal that was heard by the UNSC teams. In response, a scout vessel, {{UNSCShip|Rubicon}}, was sent to investigate. The crew discovered the remains of Guilty Spark's monitor shell among the wreckage and brought him back to the ship,<ref>'''[[Eleventh Hour reports|Eleventh Hour report 4]]'''</ref> where he told them [[Halo: Primordium|his life story]]. Afterward, his crippled shell was jettisoned into space. Just before this, however, he uploaded his consciousness into the ship's computer, purged its AI, rendered the crew unconscious, and set a course for where he believed the [[Librarian]] to be.<ref>'''Halo: Primordium'''</ref>

In mid [[2559]], the [[Banished]] and the crew of the UNSC ''Spirit of Fire'' fought for control over the Ark, which by then had fully repaired itself and finished constructing [[Installation 04C|a second replacement ring]]. At some point during the conflict, the Banished encountered a number of surviving Flood forms in an underground chamber, inadvertently starting a second Flood outbreak on the Ark, and validating the Gravemind's final warning.<ref name="WN">[https://www.halowaypoint.com/en-us/news/introducing-halo-wars-2-awakening-the-nightmare '''Halo Waypoint''' ''- Introducing Halo Wars 2: Awakening the Nightmare'']</ref>
