After the [[Battle of the Citadel|collapse]] of the Covenant and the Battle of Installation 00, the [[Great Schism]] would continue as the [[Sangheili-Jiralhanae war]] and still ongoing as of [[2559]], after the [[Created]] [[Created conflict|uprising]] in [[2558#October|late 2558]].{{Ref/Novel|Evo|Section=The Return}}

{{Main|Battle for Earth}}

While [[Terrence Hood|Lord Terrence Hood]] was suspicious of Cortana's warning and objected to going through the portal, Commander Keyes, John-117, and Rtas 'Vadum all indicated their wish to proceed through the Portal. Unwilling to leave Earth defenseless against the incoming Flood threat, Lord Hood remained on Earth. He gave Miranda Keyes command of the {{UNSCShip|Forward Unto Dawn}} for the human commitment to the mission and the fleet of ships chased after the High Prophet of Truth.{{Ref/Reuse|floodgate}}

The Fleet of Retribution exited slipspace in the vicinity of the Ark on [[2552#December|December 11, 2552]], where they found [[Truth's fleet|the Prophet of Truth's fleet]] waiting for them. Despite being outnumbered three-to-one, Rtas 'Vadum declared that they were fairly matched, and the Sangheili ships and the ''Forward Unto Dawn'' promptly engaged Truth's fleet. In the ensuing [[space warfare|space battle]], the Jiralhanae and Sangheili cruisers blended into each other.{{Ref/Level|H3|The Ark (level)|The Ark|Quote=Their cruisers mixed with ours! Watch your fire!|Quotee=Jiralhanae Commander}} 'Vadum and Keyes coordinated their attacks against the Covenant fleet; whereas the Sangheili ships and the ''Dawn'' focused their attacks on the Covenant cruisers,{{Ref/Level|H3|The Ark (level)|The Ark|Quote=Let the Elites handle those cruisers!|Quotee=Miranda Keyes}} the ''Dawn''{{'}}s Longsword fighters engaged the Seraphs.{{Ref/Level|H3|The Ark (level)|The Ark|Quote=Stay away from those cruisers!|Quotee=Rtas 'Vadum}}{{Ref/Level|H3|The Ark (level)|The Ark|Quote=Understood. Engage those Seraphs!|Quotee=Miranda Keyes}} However, the ''Dawn'' was ill-equipped to fight against large opponents like ''CAS''-class assault carriers and ''CCS''-class battlecruisers. Thus, at the start of the battle, the ''Dawn'' deployed six [[D77H-TCI Pelican]]s to the surface to search for a landing zone for the ''Dawn'' and gather intelligence on Truth's location.{{Ref/Reuse|theark}}

While John-117 and his team traveled to the first tower, 'Vadam and Johnson, along with their teams, touched down at the second and third towers, respectively. Although John-117 and 'Vadam succeed in disabling two of the three towers, Johnson was ambushed by enemy reinforcements, and lost contact with the UNSC soon after. The Jiralhanae captured Johnson, and took him to the Citadel. The UNSC-Sangheili forces launched a second assault on the third tower, with John-117 escorting the dropships in an AV-14 Hornet. They first destroyed Covenant Banshees and a Phantom, securing air control outside the barrier. The third tower was heavily defended by a pair of AA Wraiths, Shades, another standard Wraith, and a huge group of Jiralhanae led by War Chieftain. Destroying the Brute defenders outside the third tower, John-117, Thel 'Vadam, and a team of five Sangheili proceeded inside, where they discovered the corpses of Johnson's team, except for Johnson. After the defending forces of Mgalekgolo, Yanme'e and Jiralhanae were eliminated, John-117 disabled the barrier tower, finally deactivating the barrier. The ''Shadow of Intent'' advanced towards the Citadel, but 'Vadum's attack was interrupted by the arrival of the Flood-infested ''High Charity'', which arrived via slipspace. ''High Charity'' launched debris that crippled the carrier and its weapons systems, forcing the ''Shadow of Intent'' to retreat. It also launched [[Flood dispersal pod]]s and began spreading Flood across the Ark. Keyes insisted that the Flood's arrival would only pressure Truth into activating the rings, and ordered the remaining ground forces to attack the Citadel.{{Ref/Reuse|cov}}

Fighting through the Flood to exit the third tower, John-117 and the Sangheili regrouped with Gunnery Sergeant Stacker's Marines, now supported by a Scorpion, a Gauss Warthog, and a Mongoose. The humans and Sangheili fought through the cliffs to the area outside the Citadel, where the Covenant have set up lookout towers, Shade turrets, and ground vehicles. The Covenant attempted to reinforce their troops by a large amount of Banshees, but the UNSC air forces counterattacked with Hornets and Pelican gunships. The ground forces led by John-117 punched through the remaining Covenant armor on the mountainside. With the UNSC's arrival imminent, the Covenant deployed two final Scarabs, each commanded by a Jiralhanae War Chieftain, at the entrance to the Citadel, further supported by Prowlers, Ghosts, and Banshees. However, their efforts were in vain, and, with the Scarabs destroyed by John-117, any remaining Covenant stragglers were soon moped up by the UNSC.{{Ref/Reuse|cov}}

Johnson attempted to goad the Chieftain that was holding him into killing him, but Truth, realizing this, stopped the Chieftain. With John-117 and the Arbiter too far away to stop Truth, Commander Keyes took her Pelican dropship and crashed it directly into the facility in an attempt to rescue Johnson, but she was killed by Truth himself when she hesitated to kill Johnson and herself to deny Truth a means to activate the rings. Johnson, struck by grief and shock, was easily made to activate the Array. However, Keyes' actions delayed Truth long enough for John-117 and the Arbiter to stop him. The Gravemind dispatched a swarm of [[Pod infector]]s and [[Flood combat form]]s, led by two [[Flood tank form]]s, to assist the UNSC-Sangheili force in preventing the Halos' activation. They were met by the Jiralhanae Chieftain and his Unggoy, Kig-Yar and Jiralhanae.{{Ref/Reuse|cov}}

With the index secured, Thel 'Vadam ordered Rtas 'Vadum to take the human and Sangheili survivors to leave the Ark, using the slipspace portal to Earth. 'Vadam accompanied John-117 and Cortana to the incomplete Halo. Sergeant Major Johnson piloted the UNSC ''Forward Unto Dawn'', which was left behind for their escape, to a safe location near the control room, then drove a Warthog to the control room. The Gravemind, meanwhile, had begun to rebuild itself on the new ring, and sent [[Flood dispersal pod]]s to stop the three interlopers. John-117, 'Vadam, and Johnson, with the assistance of local Sentinels, fought through the Flood and entered the Control Room. Inside, Spark explained that the new Halo would be ready to fire within days, to which the group, particularly Johnson, protested. When Guilty Spark informed the three 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.{{Ref/Reuse|halo}}

==Aftermath==

===The Covenant===

{{Main|Covenant loyalists|Covenant remnants}}

Although the Battle of Installation 00 marked the end of the Human-Covenant War, numerous new [[Covenant remnants|splinter factions from the Covenant]] were created in its wake. These factions ranged from pragmatic mercenaries to fanatical religious cultists.{{Ref/Comic|Halo: Escalation|Issue=[[Halo: Escalation Issue 5|5]]}} These factions would come into [[Post-Covenant War conflicts|conflict with each other]], with notable conflictslike [[Sangheili-Jiralhanae war|a war between the Sangheili and the Jiralhanae]] following the Great Schism, and [[Blooding Years|numerous civil conflicts]] fought between the Swords of Sanghelios and various other Sangheili factions.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/universe/locations/sanghelios|Site=Halo Waypoint|Page=Universe - Locations - Sanghelios|D=20|M=10|Y=2021}}

==Legacy==

The wreckage from the Battle of Installation 00 remained on the surface of the Ark.{{Ref/Level|Id=HW2|HW2|A New Enemy}}{{Ref/Level|Id=wrong|HW2|What Could Go Wrong?}} Over two years later on [[2555|March 20, 2555]], during [[Operation: FAR STORM]], [[Luther Mann]] and [[N'tho 'Sraom]] arrived at the Citadel to stop the Halos from firing. Scattered around the basin were the remains of human and Covenant vehicles left over from the battle, including the empty husks of the two [[Type-47B Scarab|Scarabs]].{{Ref/Reuse|HitD252}} The firing of the Halo ring caused unprecedented damage to the Ark while sterilizing most of the Flood forces around and on the installation, including the Gravemind commanding the massing Flood amid the battle. Installation 00 was severely damaged,{{Ref/Reuse|epi}} and its monitor [[000 Tragic Solitude]], although inflicted with a state of [[rampancy]] from the ring's explosion, began repairing the installation.{{Ref/Book|Halo Mythos: A Guide to the Story of Halo|Page=154-155}}  

In [[2558#September|September 2558]], the [[Jiralhanae Chieftain]] [[Hekabe]] attempted to unleash the [[Sharquoi]] on the planet [[Carrow]], having retrieved the Sharquoi control device, the ''[[vertex]]'', from the Ark during the Battle of Installation 00. Hekabe's plan was narrowly foiled by [[Gray Team]], [[Rojka 'Kasaan]] and elements of the [[Surakan Militia Volunteers]].{{Ref/Reuse|envoy}}
