'''Tactical Flood Victory'''

*Quarantine Zone fails

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.

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>  

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}}

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}}

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}}

===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.
