The '''Battle of the Quarantine Zone''' was a [[battle]] which took place on [[Installation 05]] in [[2552]], as the [[Covenant Empire|Covenant]] and [[United Nations Space Command|UNSC]] fought through the [[Quarantine Zone]] in search of the [[Activation Index]], known to the Covenant as the Sacred Icon. The battle encompassed an extended conflict between [[Flood]] and [[Forerunner]] [[Sentinels]] that stretched back nearly 100,000 years.

==Background==
The establishment of the Quarantine Zone is rooted in ancient history - approximately 3,000 years after the [[Great Purification|activation]] of the [[Halo Array]], the Flood under containment on [[Installation 05]] were released. Under normal circumstances [[Sentinel]] guards would have been able to keep the parasite under control. Unfortunately, the Flood had access to [[Flood combat form|hosts]], and were able to hold off the constructs.

At some point, Installation 05's [[Monitor]] [[2401 Penitent Tangent]] was warned by [[Unidentified ancilla (Installation 05)|a Forerunner ancilla]] of a pending outbreak in one the installation's [[Flood]] [[Flood containment facility|containment facilities]]. The monitor continued to ignore this warning, and those that followed, for millennia. Within [[2552|99,779 years]], the containment facility had been overrun by the Flood, with lockdown protocols in effect within the Halo's [[teleportation grid]] to prevent further infestation.<ref>'''[[Halo 3]]''', [[multiplayer]] map ''[[Cold Storage]]'' [[Cold Storage Reports|transmissions]]</ref> Eventually, the full force of the installation's [[Sentinel]]s and [[Enforcer]]s was mobilized, and a [[Quarantine Zone]] was established, surrounded by an enormous [[Sentinel Wall|wall]] projecting a powerful [[Containment Shield]].<ref name="icon">'''[[Halo 2]]''', campaign level, ''[[Sacred Icon]]''</ref><ref name="zone">'''Halo 2''', campaign level, ''[[Quarantine Zone]]''</ref>

The establishment of the Quarantine Zone was too late to prevent the formation of a [[Gravemind]]. Over the centuries, the Gravemind's reach spread throughout the installation,<ref name="ReferenceA">'''Halo 2''', campaign level ''[[Regret (Halo 2 level)|Regret]]''</ref> eventually capturing the [[monitor]] of the installation, [[2401 Penitent Tangent]], giving him access to the [[teleportation grid]] and causing the structures on the Installation to fall into disrepair.<ref name="gravemind">'''Halo 2''', campaign level, ''[[Gravemind (level)|Gravemind]]''</ref> 

In [[2551]], a small [[Covenant]] team found a [[Luminary]] on [[Meridian]] after a [[Battle of Meridian|battle]] on the moon.This Luminary was delivered to the [[Prophet of Regret]], one of the three ruling [[Hierarchs]] of the Covenant. By late 2552, two [[Steward]]s assigned to decrypt the Luminary finally revealed its content to the Prophet of Regret: the locations of the Halo rings, including Installation 05. Hastily assembling a [[Fleet of Sacred Consecration|fleet]] of fifteen warships, the Prophet made his way toward the [[Earth|planet]] that housed the [[Portal at Voi|gateway portal]] to the [[Installation 00|Ark]], unaware that the planet was in fact [[human]]ity's heavily defended homeworld.<ref>'''[[Halo 2: Anniversary]]''' - ''[[Terminal (Halo 2: Anniversary)|Terminal]] "Beholden"''</ref> After a failed [[Battle of Earth|invasion]] of Earth, [[Prophet of Regret|Regret]] fled to Installation 05 aboard his [[flagship]] ''[[Solemn Penance]]'', pursued by the {{UNSCShip|In Amber Clad}}.<ref>'''Halo 2''', campaign level, ''[[Metropolis]]''</ref>

==The Battle==
===UNSC Incursion===
{{Quote|Proceed to the [[Index|objective]], we'll hold out as long as we can!|Gunnery Sergeant [[Marcus Stacker]], as the released flood overwhelm UNSC forces inside the Sentinel Wall.}}

[[File:H2A-In Amber Clad Quarantine Zone.png|thumb|left|300px|The {{UNSCShip|In Amber Clad}} holds position near Delta Halo's library.]]

Shortly after arriving in the [[Coelest system]] in pursuit of the ''[[Solemn Penance]]'', Commander [[Miranda Keyes]] of the {{UNSCShip|In Amber Clad}} demanded the AI [[Cortana]] provide her with all information from the [[Installation 04|installation]] her father had discovered a month prior.<ref>'''Halo 2''', campaign level ''[[Delta Halo]]''</ref> Keyes was able to locate [[Installation 05]]'s Library, and set out to reach it and secure it's [[Activation Index]] before the Covenant could do so. Marine forces lead by [[Sergeant Major]] [[Avery Johnson]] were ordered to extract from their positions on the ring's surface and rendezvous with the ''In Amber Clad'' at the Library while [[SPARTAN-II program|Spartan]] [[John-117]] proceeded on his mission to [[Assassination of the Prophet of Regret|assassinate]] the Prophet of Regret.{{Ref/Reuse|ReferenceA}}

Upon arriving at the [[Sentinel Wall]] surrounding the Library and the [[Containment Shield]] it projected, the In Amber Clad searched for a way around the obstacle.<ref>'''Halo 2''', campaign level, ''[[Regret (Halo 2 level)|Regret]]''</ref> After failing to gain access to the Library, the frigate deployed a platoon-sized force of Marines to an entrance in the wall, led by Gunnery Sergeant [[Marcus Stacker]] and Staff Sergeant [[Banks]]. The Marines moved through the outer wall with ease, unmolested by local Sentinel defenses - possibly due to being recognized by the automated guardians as [[Reclaimers]]. As the Marines moved through the inner wall, the outer wall became besieged by [[Jiralhanae]]-led Covenant forces deployed from the recently arrived [[High Charity]]. Eventually, the Arbiter [[Thel 'Vadamee]] was able to deactivate the Containment Shield, and the inner wall quickly became overrun with [[Flood]] from the nearby [[quarantine zone]]. Spread throughout the wall in small [[fireteam]]s and completely unaware of the nature of enemy they were facing, most of the platoon was quickly assimilated by the parasite, proceeding to take up arms against their former comrades. Additionally, the local Sentinel forces became hostile to the surviving Marines, likely due to the immediate presence of the Flood. With his forces decimated, but the Containment Shield now disabled, Stacker radioed ''In Amber Clad'' suggesting Keyes proceed straight to the Library while his troops attempted to hold their position. A short time later, Stacker made contact with Keyes once again, confirming their engagement with non-Covenant hostile lifeforms, while Banks could be heard organizing other Marine survivors as they staged a desperate defense.{{Ref/Reuse|icon}}

The ''In Amber Clad'' swiftly took advantage of the lowered Containment Shield, entering the Quarantine Zone as battle raged between hostile Sentinel forces and the Flood. The Frigate took position above the east-most of three large structures in the center of the zone, each containing a gondola leading to the Library. Multiple [[M808 Scorpion]]s and [[M12 Warthog]]s were deployed via [[D77-TC Pelican|dropship]], and the UNSC forces secured the east and cetral gondolas, and established several defensive positions throughout the central Quarantine Zone. UNSC superiority would be short-lived, as the Flood's acquisition of vehicles brought by the In Amber Clad and arriving Covenant forces swung the battle in their favor. With the subsequent destruction of a [[Sentinel manufacturing facility]] reinforcing the Quarantine Zone, the Flood presence quickly became overwhelming. A sizable UNSC force made a final stand outside the western gondola structure, utilizing multiple stationary [[M247 machine gun]] turrets. Despite receiving reinforcements during the battle from a stray UNSC Pelican carrying a Scorpion, the position was overrun, the Pelican shot down and the Scorpion left abandoned. Meanwhile at the western structure, Commander Keyes lead Sergeant Johnson and a squad of Marines aboard the eastern Gondola. Moments later, [[Covenant Special Operations]] forces launched the western gondola, in close pursuit.{{Ref/Reuse|zone}}

As Johnson and Keyes arrived at the Library, four Marines were killed by a horde of Flood combat forms. After securing the facility, Johnson left Corporal [[Perez (Marine)|Perez]] and [[McKenzie (Marine)|McKenzie]] to guard the exit while he escorted Keyes to retrieve the Index, however the Marines would be killed by a swarm of [[Pod infector]]s. Johnson and Keyes thus had no warning as a cloaked Thel 'Vadamee ambushed them, and arriving Jiralhanae forces led by the Chieftain [[Tartarus]] subsequently captured the index, taking the unconscious Johnson and Keyes as prisoners.{{Ref/Reuse|zone}}

With the majority of the ship's Marine complement killed in action, the ''In Amber Clad'' was eventually overrun by the surging Flood presence, and it's entire crew presumably killed. A number of Marine survivors from the battle were captured by Covenant forces,{{Ref/Reuse|gravemind}} including Sergeants Banks and Stacker.<ref>'''Halo 2''', campaign level, ''[[The Great Journey (level)|The Great Journey]]''</ref>

===Covenant intervention===
{{Quote|We shall cut into the heart of this infestation, retrieve the Icon, and burn any Flood that stand in our way!| Special Operations Commander Rtas 'Vadumee after learning of the Arbiter's mission}}
[[File:H2A - Rtas rallying troops.jpg|thumb|250px|left|Rtas rallying his troops]]
After numerous waves of [[Jiralhanae]]-led forces failed to breach the outer wall, Thel 'Vadamee, the Arbiter of the Covenant, was personally ordered by the Prophets to journey to the surface of the ring to retrieve the [[Sacred Icon]]. Dropped directly to the wall by a [[Type-52 Troop Carrier|Phantom]] transport, the Arbiter encountered a small number of surviving [[Unggoy]] and [[Kig-Yar]] from the earlier assault. After battling through numerous Forerunner constructs to reach the control center for the Containment Shield, the Arbiter deactivated the shield, proceeding to the inner wall. After his evac Phantom was driven off by a Sentinel Enforcer, 'Vadamee was forced to travel through the now-Flood infested inner-wall. He picked up multiple transmissions from the dwindling human forces that had made it through the wall first, observing two small fireteams of Marines being overwhelmed by Flood forms.{{Ref/Reuse|icon}}

As the Arbiter moved through the Sentinel Wall, Covenant Special Operations forces were deployed to the Quarantine Zone, along with vehicular support, unfortunately exacerbating the Flood outbreak. The Flood's numbers swelled as they assimilated both humans from the {{UNSCShip|In Amber Clad}} and Covenant warriors. With these new hosts, the Flood gained access to more sophisticated equipment, [[weapons]] and combat vehicles, magnifying the danger the outbreak presented immeasurably. The Flood used numerous [[Wraith]] tanks to destroy one of the Forerunner [[Sentinel manufacturing facility|Sentinel manufacturing plants]], bringing it crashing down on the surface and slowing the production of Sentinels and Enforcers, swinging the tide further in their favor.{{Ref/Reuse|icon}}

The Arbiter exited the Sentinel Wall as [[Covenant drop pod|drop pods]] containing [[Special Operations Sangheili]] arrived in the quarantine zone. 'Vadamee moved to assist his brothers in repelling the local Flood forces in the valley. One of the Sangheili told 'Vadamee that they needed to rendezvous with their [[Special Operations Commander|commander]], [[Rtas 'Vadum]]ee who had landed deeper into the zone. The group made their way through the valley, fighting off numerous Flood forms before locating 'Vadumee who, along with other Elites, was defending a small Covenant camp, repelling the Flood until more vehicles could be delivered. With the assistance of Thel 'Vadamee, the group was able to secure the camp and use it as a staging area for their push towards the installation's [[Library]]. The group traversed the war-torn wastes of the quarantine zone, facing massive numbers of Flood forms controlling both UNSC and Covenant vehicles as well as surviving Forerunner constructs before reaching the gondola entrance points to the Library of Delta Halo. After noticing human forces had already departed, 'Vadumee boarded a gondola alongside a squad of Special Operations troops while Rtas 'Vadumee stayed behind to defend the Gondola station.{{Ref/Reuse|zone}}

Human forces had gained access to the Library first, but only by a matter of minutes. The Arbiter exited the Gondala while his fellow Sangheili warriors stayed aboard to guard it, as it was the only entrance/exit. Upon exploring the interior of the Library, it was clear that the humans had faced stiff opposition, all but two of their forces had died combating the Flood and Sentinels already within its walls. Thel 'Vadamee found Commander [[Miranda Keyes]] and [[Avery Junior Johnson|Sergeant Johnson]] within the Index Chamber, having retrieved the Index seconds before his arrival. Sergeant Johnson was ready, armed with a [[BR55 Battle Rifle|Battle Rifle]], along with Miranda Keyes who was reaching for the Index holding on to a large wire from a downed enforcer. Miranda secured the Index and drew two [[M7/Caseless Submachine Gun|SMGs]]. Johnson called for his Marines, but received no answer and armed his weapon. An active-camouflaged Arbiter ambushed the pair, incapacitating both in a matter of moments. The arrival of [[Tartarus]] and his hostile Jiralhanae forces within the Chamber, after making their way through the Sangheili forces guarding the Gondala, signified the beginning of the [[Great Schism]]. Tartarus briefly told the Arbiter how the Sangheili had been expelled from the Covenant  under the orders of the High Prophet of Truth, and proceeded to attack the Arbiter, sending him plummeting to his doom deep within the Library, towards the [[Gravemind]].{{Ref/Reuse|zone}}

===Conclusion===
The battle itself was a decisive Covenant victory. They succeeded in obtaining the Index, captured the UNSC leadership as well as all surviving Marines, providing them with the [[Reclaimers]] required to activate the Installation. The Flood also won a tactical victory, securing an immense number of hosts, weapons and vehicles, escaping the Quarantine Zone, and capturing a slipspace-capable starship in the {{UNSCShip|In Amber Clad}}, which they would later use to begin their [[Fall of High Charity|infestation]] of [[High Charity]].<ref>'''Halo 2''', campaign level, ''[[High Charity (level)|High Charity]]''</ref> UNSC forces failed to recover the Index, lost the ''In Amber Clad'' and it's crew to Flood, and suffered total casualties, aside from the small number of survivors captured by the Covenant from the Library and Sentinel Wall.
