The '''Battle of Onyx''' was a very large and prolonged military engagement between the [[Forerunner]] [[Sentinel]]s of the planet Onyx, [[United Nations Space Command]] and the [[Covenant Separatists]].
The '''Onyx Conflict'''<ref>[https://www.halowaypoint.com/en-us/universe/characters/kelly-087 '''Halo Waypoint''': ''Kelly-087'']</ref> was a military engagement between the [[Forerunner]] [[Onyx Sentinel|Sentinels]] of the planet [[Onyx]], the [[United Nations Space Command]], and a [[Joyous Exultation Covenant|fledgling Covenant splinter group]]. The UNSC [[operation]] to reinforce the stranded UNSC forces on Onyx was codenamed '''Operation: CIRRUS'''.{{Ref/Game|Id=H5GLtd|Halo 5: Guardians Limited Edition|[[Halo 5: Guardians Limited Edition dossiers#Frederic-104|Dossier files]] - Frederic-104}}
 
==Battle==
===The Sentinel activation===
When [[Installation 04|Alpha Halo]] was almost activated,{{Ref/Novel|GoO|Page=175|Quote=Halsey: That timing coincides with the activation of an alien weapon world - before John thankfully destroyed it. It is no coincidence that the Sentinels appeared then. It must be part of a larger Forerunner plan.}} it emitted a signal that placed all other [[Forerunner]] installations in standby mode, including the Sentinels guarding the [[Sarcophagus|shield world]] located within the artificial world of [[Onyx]]. The Sentinels themselves first appeared on the morning of [[2552#September|September 21, 2552]].{{Ref/Novel|GoO|Page=175}} On [[2552#October|October 31, 2552]], the first of these Sentinels to awaken suddenly began attacking [[United Nations Space Command|UNSC]] forces on and near [[Onyx]]. Coincidentally, [[SPARTAN-III Gamma Company|Gamma Company]] was participating in the top honors exercise at the time.<ref>'''Halo: Ghosts of Onyx''', ''pages 117-120''</ref>


==Events==
Almost immediately, [[Team Gladius]] and the orbiting {{UNSCShip|Agincourt (frigate)}} were destroyed and [[Team Katana]] lost after passing to Zone 67. The [[SPARTAN-III program|SPARTAN-III]] trainers, save for [[Franklin Mendez|SCPO Mendez]] and [[Kurt Ambrose]] were all killed as well. In accordance with emergency protocols, Zone 67's AI [[Endless Summer]] assumed complete command of all UNSC forces on Onyx.<ref>'''Halo: Ghosts of Onyx''', ''pages 122''</ref> Shortly afterward, [[Team Saber]] regrouped with Kurt-051, [[Tom-B292]], [[Lucy-B091]] and [[Franklin Mendez|SCPO Mendez]], although they had no means of summoning reinforcements from the rest of the UNSC. [[Franklin Mendez|Mendez]] declared [[Bloody Arrow]] via UNSC E-Band.<ref>'''Halo: Ghosts of Onyx''', ''page 159''</ref>
===Sentinel Activation===
When [[Alpha Halo]] was destroyed, it emitted a signal that placed all other Forerunner installations in standby mode, including the [[Sentinels]] guarding the [[Shield World]] located within the artificial world of [[Onyx]]. On October 31, [[2552]], the first of these Sentinels to awaken suddenly began attacking UNSC forces on or near Onyx. Coincidentally, [[Gamma Company]] was participating in the Top Honors exercise at the time.


Almost immediately, [[Team Gladius]] and the orbiting {{UNSCShip|Agincourt}} were destroyed and [[Team Katana]] captured. The SPARTAN-III trainers, save for [[SCPO Mendez]] and [[Kurt-051]] were all killed as well. [[Team Saber]] regrouped with Kurt-051, [[Tom-B292]], [[Lucy-B091]] and SCPO Mendez, although they had no means of summoning reinforcements from the rest of the UNSC. Mendez declared [[Bloody Arrow]].
On November 3, [[Catherine Halsey|Dr. Halsey]], [[Kelly-087]] and [[Artificial intelligence|AI]] [[Jerrod]] arrived at Onyx aboard ''[[Beatrice]]''. Attacking Sentinels forced the ship to crash land on the planet, although all three passengers survived to link up with Kurt-051's group. Halsey proceeded to convince the resident [[Office of Naval Intelligence|ONI]] AI, Endless Summer, to send a distress message to Earth using the [[Slipspace COM launcher]]. In the signal Halsey requested the deployment of [[SPARTAN-II Program|SPARTAN-IIs]] to Onyx.<ref name="goo182">'''Halo: Ghosts of Onyx''', ''page 182-184''</ref> The launcher was destroyed shortly after firing.<ref>'''Halo: Ghosts of Onyx''', ''page 313''</ref>


[[Dr. Catherine Elizabeth Halsey]], [[Kelly-087]] and [[AI]] [[Jerrod]] arrived aboard ''[[Beatrice]]''. Attacking Sentinels forced the ship to crash land on the planet, although all three passengers survived to link up with [[Kurt-051]]'s group. Halsey proceeded to convince the resident [[ONI]] AI, [[Endless Summer]], to send a distress message to the UNSC using the [[Slipspace COM Launcher]]. In the signal Halsey requested the deployment of [[SPARTAN-II|SPARTAN-II's]] to Onyx. The launcher was destroyed shortly after firing.
Using Cortana's distress signal from Installation 05 as a "carrier wave",{{Ref/Reuse|goo182}} the message succeeded in reaching a [[Battle of Earth|besieged Earth]] in mere hours and diverting [[Blue Team]] to [[Onyx]].<ref>'''Halo: Ghosts of Onyx''', ''page 211-213''</ref> However, en route the message had been intercepted by the [[Joyous Exultation Covenant|Covenant]]. The newly promoted [[Sangheili]] [[Fleet Master]] [[Voro Nar 'Mantakree]] of the [[Second Fleet of Homogeneous Clarity]] was deployed to Onyx under orders to destroy all UNSC forces and recover any Forerunner artifacts, as the Sangheili had not yet made a formal alliance with the UNSC.<ref>'''Halo: Ghosts of Onyx''', ''page 243''</ref>


The message succeeded in reaching a [[Battle of Earth|besieged Earth]] and diverting [[Blue Team]] to Onyx. However, en route the message had been intercepted by the [[Covenant]]. The newly promoted [[Fleet Master]] [[Voro Nar 'Mantakree]] of the [[Second Fleet of Homogeneous Clarity]] was deployed to Onyx under orders to destroy all UNSC forces and recover any Forerunner artifacts.
===Blue Team and the Covenant arrive===
Blue Team, composed of [[William-043]], [[Linda-058]], and [[Frederic-104]], arrived at Onyx aboard the commandeered ''[[Bloodied Spirit]]'', but were forced to make their way down to the surface in a [[Dextro Xur-pattern Spirit|Spirit]] when their ship was attacked by Sentinels. Linking up with [[Kurt-051]]'s group they planned to attack [[Zone 67]]. Using the Spirit, they flew into a crater and discovered a Forerunner city.<ref>'''Halo: Ghosts of Onyx''', ''pages 267-274''</ref>


===Blue Team and the Covenant Arrive===
At the same time, 'Mantakree's forces formed around the flagship ''[[Incorruptible]]'' and began nearing Onyx. The destroyer ''[[Far Sight Lost]]'' was sent ahead to scout the environs but was quickly engaged and destroyed by Sentinels. Another scout, ''[[Absolution]]'', was ordered to perform a precision [[Slipstream space|Slipspace]] jump to the northern polar areas of Onyx, but the Sentinels followed it through Slipspace and the ''Absolution'' was destroyed upon exiting Slipspace.<ref>'''Halo: Ghosts of Onyx''', ''pages 280-283''</ref> However, sufficient information had been gathered and 'Mantakree ordered his ground troops, including [[Sangheili]] from the [[E'Toro Warrior Crèche|E’Toro]], [[R'Lan Warrior Crèche|R’Lan]] and [[N'Noro Warrior Crèche|N’Nono]] warrior crèches, to converge on Zone 67.<ref>'''Halo: Ghosts of Onyx''', ''pages 350''</ref>

Linking up with [[Kurt-051]]'s group they planned to attack [[Zone 67]]. Using the Spirit they flew into a crater and discovered a Forerunner city.  
===Patterson's battlegroup arrives===
Shortly after 'Mantakree had engaged the Sentinels, the {{UNSCShip|Dusk}} arrived by Slipspace from [[Earth]], having utilized the ''Bloodied Spirit''<nowiki>'</nowiki>s [[Slipstream space#Slipspace wake|slipspace wake]]. The prowler provided advanced intelligence for a [[Patterson's battle group|battlegroup]] under the command of [[Admiral]] [[Carl Patterson]] that arrived shortly thereafter. Intending to catch the enemy off guard, the UNSC force homed in on a group of Covenant destroyers and destroyed all but one destroyer. The {{UNSCShip|Glasgow Kiss}} was sacrificed to preserve the {{UNSCShip|Stalingrad}} from plasma fire from the lone destroyer. The ''Glasgow Kiss'' intercepted three of the four lances of fire and launched 12 escape pods before it was destroyed.<ref>'''Halo: Ghosts of Onyx''', ''page 294''</ref>


At the same time, [['Mantakree|'Mantakree's]] forces formed around the flagship ''[[Incorruptible]]'' and began nearing Onyx. The destroyer ''[[Far Sight Lost]]'' was sent ahead to scout the environs but was quickly engaged and destroyed by Sentinels. Another scout, ''[[Absolution]]'', was ordered to perform a precision [[Slipspace]] jump to the northern polar areas of Onyx, but the Sentinels followed it through Slipspace and the ''Absolution'' was destroyed upon exiting Slipspace. However, sufficient information had been gathered and 'Mantakree ordered his ground troops, including [[Elite]]s from the [[E’Toro]], [[R’Lan]] and [[N’Nono]] warrior crèches, to converge on Zone 67.
Despite taking multiple hits, the Covenant destroyer fled to the other side of Onyx, leading the UNSC force into a trap of twenty additional Covenant warships. Several more Covenant destroyers were eliminated, but the launch of a massive plasma volley forced the UNSC ships to accelerate into the attack and close the distance to forestall a second volley. Only five UNSC ships survived the charge, of which one, the {{UNSCShip|Iwo Jima}}, was destroyed when she detonated a [[nuclear weapon]] and her [[Fusion drive|engine]], destroying a further two Covenant warships and damaging six more in the ensuing explosion.<ref name="g298">'''Halo: Ghosts of Onyx''', ''page 298''</ref>


===Battlegroup Stalingrad===
Defeated once more, the remaining Covenant ships withdrew again to the opposite side of the planet but were there attacked by Sentinels who used plasma capture to destroy yet another three destroyers. Realizing their peril, the Covenant ships began to withdraw from Onyx's gravity well. Two ships were used as a rearguard and one was destroyed. 16 ships escaped in all.<ref>'''Halo: Ghosts of Onyx''', ''page 299-300''</ref>


Shortly after [['Mantakree]] had engaged the Sentinels, the {{UNSCShip|Dusk}} arrived by Slipspace from [[Earth]]. The Prowler provided advanced intelligence for [[Battlegroup Stalingrad]] that arrived shortly thereafter. Intending to catch the enemy off guard, the UNSC force homed in on a group of Covenant destroyers and destroyed all but one destroyer. The {{UNSCShip|Glasgow Kiss}} was sacrificed to preserve the {{UNSCShip|Stalingrad}} from plasma fire from the lone destroyer. Escape pods from the ''Glasgow Kiss'' were used to intercept three of the four lances of fire.<ref>''[[Halo: Ghosts Of Onyx]]'', page 294</ref>
The intervention of the Sentinels allowed the UNSC ships time to regroup around Onyx's [[XF-063 IV-1|moon]]. There ''Dusk'' laid a minefield of 14 [[HORNET Mine|HORNETs]], each rating at thirty-megatons with vacuum-enhanced loads. The UNSC warships then opened fire from behind the moon, hitting some of the enemy but causing negligible damage, but drawing the Covenant's attention. As the Covenant closed to engage and entered the field the HORNETs were detonated, destroying all but four of the remaining Covenant warships. Two of these were immediately set upon by the UNSC and destroyed. The remaining two whipped around the moon and as battle was about to be joined again, a [[Covenant fleet]] of 32 ships arrived from slipspace. Patterson's battle group was completely destroyed, except for ''Dusk'', in the one-sided engagement that followed. The UNSC battle group amazingly destroyed a total of 20 Covenant ships throughout the battle before being totally annihilated by the arrival of the new Covenant fleet.<ref>'''Halo: Ghosts of Onyx''', ''page 332-333''</ref>

Only five UNSC ships survived the charge, of which one, the {{UNSCShip|Iwo Jima}}, was destroyed when she detonated a nuclear weapon in her engine, destroying a further two Covenant warships and damaging six more in the ensuing explosion.
===Retreat to the shield world===
While the UNSC and Covenant fleets traded space-borne crossfire whilst in orbit, in the Forerunner city [[Kurt-051]]'s group of survivors was engaged by Covenant troops led personally by Voro Nar 'Mantakree. The SPARTAN-IIs and IIIs held off the enemy advance while Halsey, aided by [[Kelly-087]] and [[Franklin Mendez|Mendez]], configured Onyx's [[teleportation grid]], their means of escape. [[Dante-G188]] was killed rescuing [[Frederic-104]] from plasma and [[Type-33 Guided Munitions Launcher|Needler]] fire. Once the teleportation grid was functioning, the humans moved to the [[Sentinel manufacturing facility]] near the north pole in the aim of destroying it. At the advice of AI [[Endless Summer]], this would save Admiral Patterson's battle group. Halsey identified three key structures in the facility and they were destroyed by tricking Sentinels into firing on them.<ref>'''Halo: Ghosts of Onyx''', ''pages 313-324''</ref> Moving on, Kurt-051's group came upon [[Team Katana]] trapped in [[slipspace field pod]]s. Unable to free the prisoners, the [[human]]s were forced to bring the sarcophagi with them as they traveled to the [[core room antechamber]] where they prepared a stand against pursuing Covenant troops.<ref>'''Halo: Ghosts of Onyx''', ''pages 346-348''</ref>


Defeated once more, the remaining Covenant ships withdrew again to the opposite side of the planet but were there attacked by Sentinels who used plasma capture to destroy yet another three destroyers. Realizing their peril, the Covenant ships began to withdraw from Onyx's gravity well. Two ships were used as a rearguard and one was destroyed. 16 ships escaped in all.
While two [[legion]]s of [[Unggoy]] attacked [[Lieutenant Commander]] Kurt-051 and his forces atop the stepped structure, the remainder of the attackers set up [[stationary shield generator]]s and placed three groups of thirty Sangheili and one [[Mgalekgolo]] pair behind each shield. From this jump-off point, the Sangheili formed a wall using [[Kig-Yar point defense gauntlet]]s and began to advance through grenade and sniper fire. When the Covenant reached the first step, redeployed [[Lotus Anti-Tank Mine|Lotus mines]] killed several Sangheili and dazed Mgalekgolo. One Mgalekgolo was dispatched by Kurt-051 before they could recover. Kelly-087 engaged and killed three [[type-1 Energy Weapon/Sword|energy sword]]-wielding Sangheili and was then flanked by two more Mgalekgolo but was saved by [[Holly-G003]], who was killed in the effort.<ref name="goo360">'''Halo: Ghosts of Onyx''', ''page 360-362''</ref>


The intervention of the Sentinels allowed the UNSC ships time to regroup around Onyx's moon. There ''Dusk'' laid a minefield of 14 [[HORNET Mine|HORNETs]], each rating at thirty-megatons with vacuum enhanced loads. The UNSC warships then opened fire from behind the moon, hitting some of the enemy but causing negligible damage, but drawing the Covenant's attention. As the Covenant closed to engage and entered the field the HORNETs were detonated, destroying all but four of the remaining Covenant warships. Two of these were immediately set upon by the UNSC and destroyed. The remaining two whipped around the moon and as battle was about to be joined again, a [[Covenant Fleet]] of 32 ships arrived from Slipspace. Battlegroup Stalingrad was completely destroyed, except for ''Dusk'', in the one-sided engagement that followed. Battlegroup Stalingrad amazingly destroyed a total of 20 Covenant ships throughout the battle before being totally annihilated by the arrival of the covenant fleet.
The Spartans piled onto the two Mgalekgolo. Kurt-051 was wounded. Will-043 killed one Mgalekgolo, that had been shot by Linda-058, in hand-to-hand combat but was in turn shot and killed by the second. The last Mgalekgolo was killed by Fred-104 with a [[M41 Surface-to-Surface Rocket Medium Anti-Vehicle/Assault Weapon|Jackhammer]] missile mainly for efficiency reasons, as it could take down a Mgalekgolo with one hit.{{Ref/Reuse|goo360}}


===Retreat to the Shield World===
[[File:HM OnyxDestruction.jpg|250px|thumb|Onyx disintegrating into trillions of sentinels.]]
However, the main Covenant assault with hundreds of Sangheili, [[Type-26 Ground Support Aircraft|Banshees]] and Unggoy, was yet to come. Realizing it was futile for his diminished force to resist further, Kurt-051 ordered the survivors into the shield world while opting to remain behind to prevent the Covenant from reopening the portal. 'Mantakree ordered his troops to not fire upon the center of the chamber, while sending in Huragok with [[slipspace field shunt]]s to reopen the portal. With 'Mantakree approaching to finish off the wounded Spartan personally, Kurt-051 detonated two [[FENRIS nuclear warhead|FENRIS warheads]], killing himself and the entire enemy force in the antechamber as well as triggering the Sentinels of Onyx to "erupt" through the surface of the planet. With the portal closed, his comrades who had escaped into shield world were trapped, but unharmed.<ref>'''Halo: Ghosts of Onyx''', ''page 372''</ref>


While the UNSC and Covenant [[Fleet]]s traded space-borne crossfire whilst in orbit, in the Forerunner city [[SPARTAN-051|Kurt-051]]'s group of survivors was engaged by Covenant troops led personally by Voro Nar 'Mantakree. The Spartans (both II's and III's) held off the enemy advance while Halsey, aided by [[Kelly-087]] and [[Mendez]], configured Onyx's teleportation grid, their means of escape. [[Dante-G188]] was killed rescuing [[Fred-104]] from plasma and Needler fire. Once the teleportation grid was functioning, the humans moved to the [[Sentinel Production Facility]] near the north pole in the aim of destroying it. At the advice of AI [[Endless Summer]], this would save Battlegroup Stalingrad. Halsey identified three key structures in the facility and they were destroyed by tricking Sentinels into firing on them. Moving on, [[Kurt-051]]'s group came upon [[Team Katana]] trapped in some sort of Slipspace stasis pods. Unable to free the prisoners, the [[human]]s were forced to bring the sarcophagi with them as they traveled to the [[Core Room Antechamber]] where they prepared a stand against pursuing Covenant troops.
===Destruction of Onyx===
With the shield world closed and gated, Onyx disintegrated into its trillions of component Forerunner Sentinels. The Covenant fleet, so recently victorious against the humans, were finally obliterated by the swarm of vigilant constructs. Only the {{UNSCShip|Dusk}} managed to escape alive and intact.<ref>'''Halo: Glasslands''', ''page 48''</ref>


While two [[legions]] of [[Grunt]]s attacked [[Lieutenant Commander]] Kurt-051 and his forces atop the stepped structure, the remainder of the attackers setup stationary shield generators and placed three groups of thirty Elites and one [[Hunter]] pair behind each shield. From this jump-off point, the Elites formed a wall using shields taken from [[Jackal]]s and began to advance through grenade and sniper fire. When the Covenant reached the first step, redeployed [[Lotus Anti-Tank Mine|Lotus mines]] killed several Elites and dazed Hunters. One Hunter was dispatched by Kurt-051 before they could recover. Kelly-087 engaged and killed three [[Energy Sword|sword]]-wielding Elites and was then flanked by two more Hunters but was saved by [[Holly-G003]], who was killed in the effort.
==Aftermath==
Kelly, Fred, Ash, and the other remaining Spartans (including Dr. Halsey and Mendez) were transported from the portal to a Dyson sphere.


The Spartans piled onto the two Hunters. Kurt-051 was wounded. Will-043 killed one Hunter, that had been shot by Linda-058, in hand-to-hand combat but was in turn shot and killed by the second. The last Hunter was killed by Fred-104 with a [[M19 SSM Rocket Launcher|Jackhammer]] missile.

With the [[Shield World]] closed and gated by Kurt-051, Onyx 'disintegrated' into its trillions of component Sentinels. The Covenant Fleet, so recently victorious against the Humans, were finally obliterated by the swarm of vigilant constructs. Only the {{UNSCShip|Dusk}} managed to escape alive and intact. It is not known whether the data the {{UNSCShip|Dusk}} carried ever reached Earth.

==Trivia==
==List of appearances==
*It is interesting to note that the Separatists are fighting Humans despite the Arbiter's alliance with the UNSC. This is likely due to the amount of time for a message to be received from near Installation 05. Which, although the Incorruptible was present during the [[Battle of Installation 05]], a message would not have been sent at the time.

The Onyx Conflict[2] was a military engagement between the Forerunner Sentinels of the planet Onyx, the United Nations Space Command, and a fledgling Covenant splinter group. The UNSC operation to reinforce the stranded UNSC forces on Onyx was codenamed Operation: CIRRUS.[3]

Battle[edit]

The Sentinel activation[edit]

When Alpha Halo was almost activated,[4] it emitted a signal that placed all other Forerunner installations in standby mode, including the Sentinels guarding the shield world located within the artificial world of Onyx. The Sentinels themselves first appeared on the morning of September 21, 2552.[5] On October 31, 2552, the first of these Sentinels to awaken suddenly began attacking UNSC forces on and near Onyx. Coincidentally, Gamma Company was participating in the top honors exercise at the time.[6]

Almost immediately, Team Gladius and the orbiting UNSC Agincourt (frigate) were destroyed and Team Katana lost after passing to Zone 67. The SPARTAN-III trainers, save for SCPO Mendez and Kurt Ambrose were all killed as well. In accordance with emergency protocols, Zone 67's AI Endless Summer assumed complete command of all UNSC forces on Onyx.[7] Shortly afterward, Team Saber regrouped with Kurt-051, Tom-B292, Lucy-B091 and SCPO Mendez, although they had no means of summoning reinforcements from the rest of the UNSC. Mendez declared Bloody Arrow via UNSC E-Band.[8]

On November 3, Dr. Halsey, Kelly-087 and AI Jerrod arrived at Onyx aboard Beatrice. Attacking Sentinels forced the ship to crash land on the planet, although all three passengers survived to link up with Kurt-051's group. Halsey proceeded to convince the resident ONI AI, Endless Summer, to send a distress message to Earth using the Slipspace COM launcher. In the signal Halsey requested the deployment of SPARTAN-IIs to Onyx.[9] The launcher was destroyed shortly after firing.[10]

Using Cortana's distress signal from Installation 05 as a "carrier wave",[9] the message succeeded in reaching a besieged Earth in mere hours and diverting Blue Team to Onyx.[11] However, en route the message had been intercepted by the Covenant. The newly promoted Sangheili Fleet Master Voro Nar 'Mantakree of the Second Fleet of Homogeneous Clarity was deployed to Onyx under orders to destroy all UNSC forces and recover any Forerunner artifacts, as the Sangheili had not yet made a formal alliance with the UNSC.[12]

Blue Team and the Covenant arrive[edit]

Blue Team, composed of William-043, Linda-058, and Frederic-104, arrived at Onyx aboard the commandeered Bloodied Spirit, but were forced to make their way down to the surface in a Spirit when their ship was attacked by Sentinels. Linking up with Kurt-051's group they planned to attack Zone 67. Using the Spirit, they flew into a crater and discovered a Forerunner city.[13]

At the same time, 'Mantakree's forces formed around the flagship Incorruptible and began nearing Onyx. The destroyer Far Sight Lost was sent ahead to scout the environs but was quickly engaged and destroyed by Sentinels. Another scout, Absolution, was ordered to perform a precision Slipspace jump to the northern polar areas of Onyx, but the Sentinels followed it through Slipspace and the Absolution was destroyed upon exiting Slipspace.[14] However, sufficient information had been gathered and 'Mantakree ordered his ground troops, including Sangheili from the E’Toro, R’Lan and N’Nono warrior crèches, to converge on Zone 67.[15]

Patterson's battlegroup arrives[edit]

Shortly after 'Mantakree had engaged the Sentinels, the UNSC Dusk arrived by Slipspace from Earth, having utilized the Bloodied Spirit's slipspace wake. The prowler provided advanced intelligence for a battlegroup under the command of Admiral Carl Patterson that arrived shortly thereafter. Intending to catch the enemy off guard, the UNSC force homed in on a group of Covenant destroyers and destroyed all but one destroyer. The UNSC Glasgow Kiss was sacrificed to preserve the UNSC Stalingrad from plasma fire from the lone destroyer. The Glasgow Kiss intercepted three of the four lances of fire and launched 12 escape pods before it was destroyed.[16]

Despite taking multiple hits, the Covenant destroyer fled to the other side of Onyx, leading the UNSC force into a trap of twenty additional Covenant warships. Several more Covenant destroyers were eliminated, but the launch of a massive plasma volley forced the UNSC ships to accelerate into the attack and close the distance to forestall a second volley. Only five UNSC ships survived the charge, of which one, the UNSC Iwo Jima, was destroyed when she detonated a nuclear weapon and her engine, destroying a further two Covenant warships and damaging six more in the ensuing explosion.[17]

Defeated once more, the remaining Covenant ships withdrew again to the opposite side of the planet but were there attacked by Sentinels who used plasma capture to destroy yet another three destroyers. Realizing their peril, the Covenant ships began to withdraw from Onyx's gravity well. Two ships were used as a rearguard and one was destroyed. 16 ships escaped in all.[18]

The intervention of the Sentinels allowed the UNSC ships time to regroup around Onyx's moon. There Dusk laid a minefield of 14 HORNETs, each rating at thirty-megatons with vacuum-enhanced loads. The UNSC warships then opened fire from behind the moon, hitting some of the enemy but causing negligible damage, but drawing the Covenant's attention. As the Covenant closed to engage and entered the field the HORNETs were detonated, destroying all but four of the remaining Covenant warships. Two of these were immediately set upon by the UNSC and destroyed. The remaining two whipped around the moon and as battle was about to be joined again, a Covenant fleet of 32 ships arrived from slipspace. Patterson's battle group was completely destroyed, except for Dusk, in the one-sided engagement that followed. The UNSC battle group amazingly destroyed a total of 20 Covenant ships throughout the battle before being totally annihilated by the arrival of the new Covenant fleet.[19]

Retreat to the shield world[edit]

While the UNSC and Covenant fleets traded space-borne crossfire whilst in orbit, in the Forerunner city Kurt-051's group of survivors was engaged by Covenant troops led personally by Voro Nar 'Mantakree. The SPARTAN-IIs and IIIs held off the enemy advance while Halsey, aided by Kelly-087 and Mendez, configured Onyx's teleportation grid, their means of escape. Dante-G188 was killed rescuing Frederic-104 from plasma and Needler fire. Once the teleportation grid was functioning, the humans moved to the Sentinel manufacturing facility near the north pole in the aim of destroying it. At the advice of AI Endless Summer, this would save Admiral Patterson's battle group. Halsey identified three key structures in the facility and they were destroyed by tricking Sentinels into firing on them.[20] Moving on, Kurt-051's group came upon Team Katana trapped in slipspace field pods. Unable to free the prisoners, the humans were forced to bring the sarcophagi with them as they traveled to the core room antechamber where they prepared a stand against pursuing Covenant troops.[21]

While two legions of Unggoy attacked Lieutenant Commander Kurt-051 and his forces atop the stepped structure, the remainder of the attackers set up stationary shield generators and placed three groups of thirty Sangheili and one Mgalekgolo pair behind each shield. From this jump-off point, the Sangheili formed a wall using Kig-Yar point defense gauntlets and began to advance through grenade and sniper fire. When the Covenant reached the first step, redeployed Lotus mines killed several Sangheili and dazed Mgalekgolo. One Mgalekgolo was dispatched by Kurt-051 before they could recover. Kelly-087 engaged and killed three energy sword-wielding Sangheili and was then flanked by two more Mgalekgolo but was saved by Holly-G003, who was killed in the effort.[22]

The Spartans piled onto the two Mgalekgolo. Kurt-051 was wounded. Will-043 killed one Mgalekgolo, that had been shot by Linda-058, in hand-to-hand combat but was in turn shot and killed by the second. The last Mgalekgolo was killed by Fred-104 with a Jackhammer missile mainly for efficiency reasons, as it could take down a Mgalekgolo with one hit.[22]

Onyx is destroyed.

However, the main Covenant assault with hundreds of Sangheili, Banshees and Unggoy, was yet to come. Realizing it was futile for his diminished force to resist further, Kurt-051 ordered the survivors into the shield world while opting to remain behind to prevent the Covenant from reopening the portal. 'Mantakree ordered his troops to not fire upon the center of the chamber, while sending in Huragok with slipspace field shunts to reopen the portal. With 'Mantakree approaching to finish off the wounded Spartan personally, Kurt-051 detonated two FENRIS warheads, killing himself and the entire enemy force in the antechamber as well as triggering the Sentinels of Onyx to "erupt" through the surface of the planet. With the portal closed, his comrades who had escaped into shield world were trapped, but unharmed.[23]

Destruction of Onyx[edit]

With the shield world closed and gated, Onyx disintegrated into its trillions of component Forerunner Sentinels. The Covenant fleet, so recently victorious against the humans, were finally obliterated by the swarm of vigilant constructs. Only the UNSC Dusk managed to escape alive and intact.[24]

Aftermath[edit]

Kelly, Fred, Ash, and the other remaining Spartans (including Dr. Halsey and Mendez) were transported from the portal to a Dyson sphere.
