The '''Battle of Mombasa''', also known as the '''Battle of New Mombasa''',{{Ref/Reuse|opa}} was a large-scale engagement of the [[Battle for Earth]], taking place in late [[2552#October|October 2552]]. Over the course of the battle, [[Covenant Empire|Covenant]] forces attempted to capture the city of [[Mombasa]], [[Kenya]] before it was quickly retaken in a matter of hours by the [[United Nations Space Command|UNSC]].<ref name="outskirts">''[[Halo 2]]'', campaign level, [[Outskirts]]</ref><ref name="metropolis">''Halo 2'', campaign level, [[Metropolis]]</ref> However, after the [[High Prophet of Regret]]'s retreat, the city was occupied by another, larger Covenant force sent by the [[Prophet of Truth]].<ref name="bnet">[http://halo.bungie.net/News/content.aspx?type=topnews&cid=16989 ''Bungie.net'': Bungie Weekly Update: 01/23/09]</ref> In the aftermath of the battle, [[Portal at Voi|the Portal]] to [[Installation 00|the Ark]] was eventually found by the Covenant, which would prove to be a major determining factor in the final outcome of the [[Human-Covenant War]].<ref name="coastal">''[[Halo 3: ODST]]'', campaign level, [[Coastal Highway]]</ref><ref name="waypoint">''[[Halo Waypoint]]'', "Ten Twenty" history article</ref> Years after the war's end, a movement known as "[[Project Rebirth]]" emerged to endorse the eventual rebuilding of Mombasa in the aftermath of the War.{{Ref/Reuse|pointprizes}}

==Prelude==
===Covenant===
After discovering and decrypting a [[Forerunner]] [[Luminary]] found on [[Meridian]], the [[High Prophet of Regret]] of the [[Covenant]] was given [[Slipstream space|Slipspace]] coordinates to a planet called "Erde-Tyrene", which was home to a Forerunner [[Portal at Voi|slipspace portal]] leading to the [[Installation 00|Ark]]—a facility highly important to the initiation of their [[Covenant religion|"Great Journey"]]. Unknown to Regret, Erde-Tyrene was [[human]]ity's homeworld, [[Earth]].<ref>''[[Halo 2: Anniversary]]'', [[Terminal (Halo 2: Anniversary)|Terminal 14 - Beholden]]</ref> In his characteristic brash and ambitious manner, the Prophet of Regret, wishing to proceed with securing the Portal, took [[Fleet of Sacred Consecration|a hastily-assembled force]] of 15 warships to Earth. Though surprised to find not only a human presence on the planet, but a planet more fortified than any previously encountered human-held world, the [[Hierarchs|High Prophet]] deemed his mission important enough to proceed and utilized many tactics to ensure his safe arrival on the surface. The coordinates provided by the Forerunner information indicated that his quarry was around the area of [[Mombasa]], [[Kenya]]. Immediately after the [[Prophet of Truth]] learned of Regret's move, he sent [[Truth's fleet|a massive fleet]] he had collected in secrecy to pick up where Regret had left off.{{Ref/Reuse|bnet}}{{Ref/Reuse|waypoint}}

===Mombasa===
The city was relatively lightly defended, with only [[New Mombasa Police Department|NMPD forces]] as well as some Marine units present, including the [[17th Marine Regiment]].<ref>''Halo Graphic Novel'', p. 86-98</ref> Some additional military units had been transferred to the city, along with Earth's other tether cities, following the [[Fall of Reach]] to bolster their defenses in case of a Covenant invasion. These included [[E2-BAG/1/7]] as well as some [[UNSC Army]] forces.<ref name="palace">''[[Halo: Evolutions - Essential Tales of the Halo Universe]]'', "[[Palace Hotel]]", p. 367</ref>

Just prior to the Covenant's attack, [[Sadie Endesha]] was on her way to [[Magongo]] to enlist in the UNSC.<ref>''Sadie's Story'', Circle 1, Arc 1</ref> As well, photographer and journalist [[Benjamin Giraud]] was on a train heading to [[Old Mombasa]].<ref>''Halo Graphic Novel'', [[Second Sunrise Over New Mombasa]]</ref>

==The battle==
===Surprise Covenant invasion===
{{Quote|No parking, violators will be ticketed and towed!|The Superintendent discussing the assault carrier hovering over New Mombasa with Sadie Endesha.{{Ref/Reuse|sscirc1arc3}}}}
On October 20, during the opening stages of the [[Battle for Earth]], a single {{Class|CAS|assault carrier}}, the ''[[Solemn Penance]]'', broke through the [[UNSC Home Fleet]]'s defensive lines and headed towards Earth's atmosphere.<ref>''[[Halo 2]]'', campaign level, [[Cairo Station]]</ref><ref>''[[Halo Graphic Novel]]'', p. 90</ref> The ship slipspace jumped down to the city of [[New Mombasa]] in the [[East African Protectorate]].{{Ref/Reuse|sscirc1arc2}} There, the ship came to rest over the [[Uplift Nature Reserve]] deploying infantry and mechanized support.{{Ref/Reuse|upliftreserve}} One of the Covenant's first targets was the Mombasa [[Maglev train]] network.<ref>''[[Halo 2]]'', multiplayer map, [[Terminal (map)|Terminal]] level description</ref>

At the time of the ship jumping down to the city, Sadie Endesha and numerous civilians had been kicked off a train in [[Old Mombasa]].{{Ref/Reuse|sscirc1arc2}} Covenant tanks that were very quickly deployed into the city,<ref name="sscirc1arc3">''Sadie's Story'', Circle 1, Arc 3</ref> bombarded and destroyed the train in the vicinity of [[Makupa Station]].<ref name="sscirc2arc1">''Sadie's Story'', Circle 2, Arc 1</ref> NMPD Commissioner [[Kinsler]] and officer [[Mike Branley]] soon arrived on the scene, taking Sadie away from the crowd and headed for a police bunker outside the city.{{Ref/Reuse|sscirc2arc1}}

The Mombasa Tether was shut down, forcing citizens to escape the city on foot or by car.<ref name="sscirc5arc2">''Sadie's Story'', Circle 5, Arc 2</ref>

Over the course of the battle, some civilians took up arms in an attempt to defend their city, joining the Marines under command of a [[unidentified Marine officer (Mombasa)|Marine officer]].<ref>''Halo Graphic Novel'', p. 92-93</ref> These "militias" were used as a [[propaganda]] tool by the NMPD, broadcasting their exploits over PA systems.{{Ref/Reuse|sscirc5arc2}} Though a number of the stories of the militias appear to have been fabricated by [[Stephen (Mombasa)|Stephen]] at NMPDHQ, including that of "Harris 'Two-Shot' Kibaki.<ref>''Sadie's Story'', Circle 8, Arc 3</ref> These militias and armed citizens allowed for most of the people of New Mombasa to evacuate from the city to Old Mombasa using boats destined for other surrounding cities.<ref>''Halo Graphic Novel'', p. 97 & 98</ref> 

More [[UNSC Marine Corps]] and [[UNSC Army]] units later poured into the region after the initial attack, some of which arriving from [[Diego Garcia]] near India.<ref>''Halo Encyclopedia'', p. 296 (2011 edition)</ref>

====UNSC insertion====

He's on that carrier, and he's calling for help.|Sgt. Avery Johnson and Cortana discussing a Covenant distress signal, while flying in on a [[Pelican]].{{Ref/Reuse|outskirts}}}}
[[File:H2A - Pelicans.jpg|thumb|left|250px|UNSC reinforcements from the {{UNSCShip|In Amber Clad}} arrive in New Mombasa.]]
Some time after the Covenant insertion to the city and the civilian evacuation, the {{Class|Stalwart|light frigate}} {{UNSCShip|In Amber Clad}} descended near Mombasa to reinforce the ground troops already present. Intercepted transmission from the Covenant forces lead the UNSC to correctly believe that it was the High Prophet of Regret in command of the opposing force, making his capture their utmost priority. Three [[D77-TC Pelican|Pelicans]], one of them with [[John-117|SPARTAN-117]] on board, were deployed by the ''In Amber Clad'' to reclaim the city and board the ''[[Solemn Penance]]'' hovering near the [[Mombasa Tether]]. However, before they could get near the carrier, the formation ran across a [[Type-47A Scarab]] which shot down all of the Pelicans. The first was destroyed by the Scarab's main cannon, the second, carrying [[Gunnery Sergeant]] [[Stacker]] and an [[Orbital Drop Shock Trooper|ODST]] [[Second Squad#Battle of Mombasa|squad]], was shot down and landed on the beach. A third carrying [[Sergeant Major]] [[Avery Junior Johnson|Avery J. Johnson]] and the Master Chief was hit hard, crashing into a building, upside down.{{Ref/Reuse|outskirts}}

Over the course of the battle, the Covenant deployed several [[Type-47B Scarab|Scarab]] assault platforms in both the old and new sections of Mombasa, with many of them targeting the city's space elevator.<ref>''[[Halo: Evolutions - Essential Tales of the Halo Universe]]'', "[[Palace Hotel]]", p. 363</ref> The UNSC managed to trap and destroy many of them in the narrow streets of the city.<ref>''Halo 2'', multiplayer map, [[Turf]] level description</ref>

====Outskirts====
{{Quote|Here, let me give him my "Welcome to Earth" gift basket.|[[Walpole]], an ODST about to fire on a group of Covenant at Hotel Zanzibar.{{Ref/Game|H2|Detail=''[[Another Day at the Beach]]''}}}}
Both teams suffered few casualties from their respective crashes. The Spartan's team moved into a nearby bunker while Stacker's team moved up the beach to the [[Hotel Zanzibar]] and set up a command post, eliminating several Covenant units in the process. Both teams then waited in their respective locations for extraction.{{Ref/Reuse|outskirts}}

After [[John-117|Spartan-117]] and his allies repelled several waves of Covenant including a pair of [[Mgalekgolo]], a Pelican found the group and gave them coordinates of an extraction point. [[Commander]] [[Miranda Keyes]] ordered Johnson to regroup with the ''In Amber Clad'' so that he could coordinate further deployment of infantry and armor units while the Spartan continued on foot through the city to find the second squad.{{Ref/Reuse|outskirts}}

[[File:HtT John in New Mombasa original.jpg|thumb|left|A picture of John-117 during the battle taken by [[Benjamin Giraud]].|250px]]
After fighting his way through multiple alleyways filled with [[Kig-Yar Sniper]]s, John-117 found and assisted the [[Orbital Drop Shock Trooper|ODSTs]] pinned down at Hotel Zanzibar.  He then took a Warthog and spearheaded a counterattack, destroying Covenant infantry, armor, and [[Covenant artillery|Covenant artillery emplacements]] on the beaches facing [[New Mombasa]].{{Ref/Reuse|outskirts}} 

John-117 and his makeshift Marine unit entered a blown-out hole in a tunnel where they intercepted and destroyed a Covenant convoy, made up primarily of [[Type-29 Shadow]]s that had been attempting to rendezvous with the regrouping Covenant ground forces still stationed in that sector of the city. Along the way they engaged and neutralized several barricades the Covenant had assembled to fortify the tunnel network. After the engagement in the tunnels, they advanced towards the bridge connecting Old and New Mombasa. Before the Spartan got there, the Marine unit at the bridge had already exhausted itself fighting the Scarab.{{Ref/Reuse|outskirts}}{{Ref/Reuse|metropolis}}

====The Conduit====
{{Main|Operation: WINDOW PANE}}
As the ''In Amber Clad''{{'}}s force pressed towards New Mombasa, the Covenant brought the [[Conduit]]—a Forerunner device capable of opening [[slipspace portal]]s—to New Mombasa.<ref name="opa">''[[Halo: Spartan Strike]]'', [[Operation A: Orphic Spear]]</ref> A [[Type-28 Spirit|Spirit]] [[dropship]] carrying a [[data pad]] with information pertaining to the Conduit was shot down by [[UNSC]] forces.<ref name="ss1">''Halo: Spartan Strike'', campaign level, [[Mission 1: New Mombasa Nightmare|New Mombasa Nightmare]]</ref> When the data pad's relevance to the Conduit was realized by the UNSC, a [[squad]] of Orbital Drop Shock Troopers was [[Operation: WINDOW PANE|sent to recover it.]]{{Ref/Reuse|opa}} Covenant forces awaiting extraction at the crashed Spirit were attacked by the ODST squad and the [[Sangheili]] [[Field Master]] carrying the data pad was killed. With the data pad, the UNSC used the information gained to pinpoint the location of the Conduit in the city.<ref name="ss2">''Halo: Spartan Strike'', campaign level, [[Mission 2: On Top of the World|On Top of the World]]</ref> The ODST squad was directed to a Sangheili task force carrying the Conduit. After a brief engagement, the ODSTs managed to procure the Conduit from the Covenant and the device was delivered to a nearby UNSC convoy.<ref name="ss3">''Halo: Spartan Strike'', campaign level, [[Mission 3: Conduit|Conduit]]</ref>

The Covenant responded by assaulting the convoy with waves of infantry. Though the ODST squad and several Marines attempted to defend the convoy from attacking Covenant forces, a Sangheili Field Master dropped down from his Spirit into the [[M313 Elephant|Elephant]] carrying the Conduit, retrieved the device, and escaped the engagement aboard the dropship. The ODSTs gave chase and,<ref name="ss4">''Halo: Spartan Strike'', campaign level, [[Mission 4: Reversal of Fortune|Reversal of Fortune]]</ref> eventually, the Spirit was shot down. The squad located the dropship's crash site and attacked its surviving occupants. When the Field Master and his [[Kig-Yar]] bodyguards were eventually eliminated, the Conduit was reclaimed by the UNSC.<ref name="ss5">''Halo: Spartan Strike'', campaign level, [[Mission 5: Wounded Quarry|Wounded Quarry]]</ref> The ODSTs took the Conduit aboard a [[M12 Warthog|Warthog]] and were ordered to leave the city.{{Ref/Reuse|ss6}}

====Forerunner glyphs====
[[File:HSS ODST.png|thumb|left|250px|A squad during their mission to recover Forerunner intel.]]
Concurrent with the search for the Conduit, an [[unidentified ODST squad]] participated in the battle with orders to retrieve information the Covenant were interested in. Commandeering a [[Grizzly]] tank, the squad rescued marines who had recovered an emergency broadcast from a downed [[AV-14 Hornet]], stating that its crew had captured a series of [[Forerunner symbols|Forerunner glyphs]] from the Covenant. The squad then trekked their way to the site, recovered the glyphs, and escaped the city before the ''[[Solemn Penance]]'' jumped into slipspace.<ref name="ope">''[[Halo: Spartan Strike]]'', [[Operation E: Brother’s Keeper]]</ref>

====Battling for New Mombasa====
{{Quote|no=two|Sergeant [[Banks]]|Corporal [[Perez]]|q1=That thing is really starting to PISS ME OFF! Marines, time to kill us a Scarab!|q2=It's over here, sir!|Sergeant Banks and Corporal Perez talking about a Scarab heading towards the canals in New Mombasa.{{Ref/Reuse|metropolis}}}}
The Master Chief arrived at the bridge to assess the situation while Sergeant Johnson reinforced the Marines with weaponry, including a [[M808B Main Battle Tank|Scorpion tank]]. The Chief traveled across the bridge with the armored unit, clearing it of both Covenant armored and mechanized forces. These forces included [[Type-32 Rapid Attack Vehicle|Ghost]]s, [[Type-26 Wraith|Wraith]]s, [[Type-52 Troop Carrier|Phantom]]s, and [[Type-26 Ground Support Aircraft|Banshee]]s.{{Ref/Reuse|metropolis}}

[[File:scarabcannon.jpg|thumb|right|250px|The [[Type-47A Scarab|Scarab]] fires upon a [[M808B Main Battle Tank|Scorpion]] tank, destroying it instantly.]]
After the engagement on the bridge, UNSC forces entered New Mombasa in large numbers. They linked up with various squads of Marines as they moved through the city, eliminating Covenant forces that were setting up positions. The Master Chief's team worked their way into the [[Kilindini Park Cultural Center]] through the sewer system, and then towards the city center via [[Shimanzi Road]] and [[Beria Plaza]], finding that the Scarab had, likewise, taken a similar path.{{Ref/Reuse|metropolis}}{{Ref/Reuse|palace}}

Once in the heart of the [[New Mombasa industrial zone|industrial zone]] near the city center, John-117's team found a Marine outpost holed in a corporate building,{{Ref/Note|In the original version of ''Halo 2'', the building was owned by the [[Mtangulizi Kampuni]]. However, in ''Halo 2: Anniversary'', this building is now depicted under the ownership of [[Lethbridge Industrial]].}} commanded by [[Staff Sergeant]] [[Banks]] of [[A Company|"A" Company]] under siege by a unit of [[Type-26 Wraith|Wraiths]]. The UNSC forces, with the help of John-117, destroyed the Wraiths, and secured a landing zone for reinforcements. The Pelicans then dropped a platoon of Marine infantry and a Scorpion tank.{{Ref/Reuse|metropolis}}

The lumbering Scarab appeared from the other end of the plaza the Marine outpost was facing and the Scorpion tank opened fire on it, with no effect. After the Scarab destroyed the tank with its main gun, Marines opened fire on the walker, but it was unaffected and impervious to the weak rounds and climbed over their position and moved into the canals of the city. However, it soon found itself trapped inside of the walls of the canal, giving the Marines a chance to attack it openly with Pelicans.{{Ref/Reuse|metropolis}}

The Master Chief and A Company followed the Scarab through the canals and the Spartan boarded the walker. While the Marines provided some cover fire, John defeated the forces manning the Scarab walker. After defeating its command crew, he managed to destroy the Scarab from the inside. All Covenant forces soon began retreating to Regret's carrier. The Master Chief was extracted by Sergeant Johnson's Pelican and taken back to ''In Amber Clad'' along with the remaining members of A Company.{{Ref/Reuse|metropolis}}

====Regret's withdrawal====
{{Quote|no=two|[[Remi]]|[[Miranda Keyes]]|q1=Ma'am, without a destination solution—|q2=We are ''not'' losing that ship!|Miranda Keyes ordering the pursuit of the ''Solemn Penance''.{{Ref/Reuse|metropolis}}}}
[[File:H2A In Amber Clad intercept.png|thumb|right|250px|The {{UNSCShip|In Amber Clad}} gives chase as Regret's flagship prepares to flee New Mombasa.]]
The Pelicans carrying Spartan-117 and the Marines entered the ''In Amber Clad'', just as the carrier was preparing to flee. [[Fleet Admiral]] [[Terrence Hood]] was hesitant to let ''In Amber Clad'' engage Regret's assault carrier, still above Mombasa and beside the Mombasa space elevator. He instead opted to call in two heavier vessels to intercept the carrier if it returned to space. However, when the carrier initiated its slipspace drive, preparing to jump while still in the atmosphere, Hood gave the ship the green light to give chase.{{Ref/Reuse|metropolis}} The {{UNSCShip|Paris}}, {{UNSCShip|Redoutable}}, and {{UNSCShip|Coral Sea}}, and the {{UNSCShip|Dusk}} followed in the wake of the slipspace jump, with the latter ship losing contact with its companions in the slipstream.<ref name="goo22">'''[[Halo: Ghosts of Onyx]]''', ''Chapter 22''</ref>

[[File:The Drop.png|right|250px|thumb|HEV pods falling into New Mombasa moments before Regret's retreat.]]
Just before the carrier jumped, remaining ships of the UNSC Home Fleet deployed dozens of [[Single Occupant Exoatmospheric Insertion Vehicle|SOEIVs]] down to the city in [[Operation: BUMRUSH|an effort to infiltrate the carrier]], only to be caught by the [[Electromagnetic pulse|EMP]] blast in mid-flight, destroying their navigational and safety systems, plunging them and their [[Orbital Drop Shock Trooper]] occupants to almost certain death. It is likely that only [[Alpha-Nine|one Squad]] survived, having changed their course away from the carrier at the last moment. Many of the city's buildings were heavily damaged but remained standing, including the Mombasa Tether. The rupture also created a large crater in the mainland, north of New Mombasa, revealing a section of the Forerunner portal.<ref name="preparetodrop">'''[[Halo 3: ODST]]''', campaign level ''[[Prepare To Drop]]''</ref> This event would later become referred to as the New Mombasa Slipspace Event, and would lead to the reactivation of the old [[NATO]] [[Outpost C9]].<ref>'''[[Halo 3]]''', multiplayer map, ''[[High Ground]]'' map description</ref>

===Covenant reinforcements arrive===
{{Quote|We need to get above this crap, link up with the [[UNSC battle network|bee-net]]. One of our drones must have seen where they hit.|[[Edward Buck]] to [[Kojo Agu]] after meeting in Tayari Plaza.}}
[[File:Main phantom.jpg|right|250px|thumb|A [[Type-52 Troop Carrier|Phantom]] dropping troops in New Mombasa just after the Slipspace event.]]
Large numbers of Covenant troops remained in the city even after Regret's withdrawal. While most of Regret's troops evacuated into the carrier, there was still a significant Covenant presence both on the ground and in orbit. Moments after Regret jumped however, a large fleet of [[Jiralhanae]]-led Covenant reinforcements sent by the [[Prophet of Truth]] arrived, and seized control of the battle. The remaining Jiralhanae from Regret's forces were simultaneously given orders to execute the [[Sangheili]] forces on the ground while the reinforcement fleet would do the same with the remaining Sangheili ships in orbit. During the course of the battle, more and more Covenant reinforcements commanded by the Jiralhanae started arriving at Earth. This was a part of the Prophet of Truth's personal scheme for the Covenant, which would come to its conclusion two weeks later when the Sangheili were officially removed from their positions as the main warrior caste of the Covenant.{{Ref/Reuse|bnet}}{{Ref/Reuse|waypoint}}

However, a sizeable number of UNSC Marines and [[New Mombasa Police Department|NMPD]] forces remained in the city. They organized an effective resistance, and fought for control of the city throughout the remainder of the day. The city's [[Artificial intelligence|Urban Infrastructure AI]] [[Superintendent]] also had a vital role in the defense of the city.

Knocked off their course by the slipspace rupture, two ODST drop pods made rough landings: Gunnery Sergeant [[Edward Buck]]'s pod in [[Lumumba]], and Captain [[Veronica Dare]]'s in nearby [[Tayari Plaza (location)|Tayari Plaza]]. At this point in the battle, large groups of Brute led forces were being deployed into the city. Buck fought his way to Tayari Plaza to help Dare, killing large numbers of Covenant troops including a [[Mgalekgolo]] pair, but upon making it to her pod, he discovered that the Captain had disappeared. Meeting with another of his [[Kojo Agu|squad mates]] and with no idea what his objective was now, Buck took the decision to reunite with his squad and then extract them from the city as fast as possible.<ref name="tayariplaza">''Halo 3: ODST'', campaign level, [[Tayari Plaza]]</ref>

=====UNSC forces regroup=====
{{Quote|Good hunting, boys... I'm keepin' my boots on the ground.|ODST [[Taylor Miles]] commenting on a Wombat flyover of the Uplift Reserve.{{Ref/Reuse|upliftreserve}}}}
[[File:Uplift_battle.jpg|right|250px|thumb|The battle for the Covenant LZ in the Uplift Reserve.]]
Around thirty minutes after the slipspace event, the UNSC was beginning to regroup, following the orders of a [[unidentified colonel|Marine Colonel]]. The Marines' orders were to reach the Colonel's position near the city center, and take control of Regret's carrier's former landing zone in the [[Uplift Nature Reserve]] in an effort to seize an unidentified enemy asset.{{Ref/Reuse|upliftreserve}}

Remote-controlled [[F-99 Unmanned Combat Aerial Vehicle|F-99 UCAVs]] were sent to the city to maintain air supremacy over the [[Type-52 Troop Carrier|Phantom]]s and [[Type-26 Ground Support Aircraft|Banshee]]s. Meanwhile, Marines at the Uplift Reserve, led by a [[Taylor H. Miles|surviving ODST]] began to take out [[Type-26 Wraith|Wraith]]s blocking their way to the rendezvous point. Eventually, the Mombasa Tether, already damaged by the jump, collapsed, with miles of debris from the tether scattered across East Africa. The collapse also killed the Colonel.<ref name="upliftreserve">''Halo 3: ODST'', campaign level, [[Uplift Reserve]]</ref>

=====Fallback to ONI Alpha Site=====
After the UNSC reclaimed the Covenant landing zone in Uplift Reserve, defending the [[Office of Naval Intelligence]]'s [[ONI Alpha Site (location)|local headquarters]] became the top priority. Ninety minutes after the slipspace event, Marines began falling back to the building as advancing Covenant Wraith convoys prepared to lay siege to Alpha Site. The Marines were forced to fight through enemy forces in the [[Kizingo Boulevard|Boulevard]] that led to the ONI site before falling back further into the ONI complex.<ref name="kizingoboulevard">''Halo 3: ODST'', campaign level, [[Kizingo Boulevard]]</ref>

[[File:Alphas destro.png|thumb|left|250px|The Alpha Site is destroyed.]]
Within the ONI compound, the Marines and the NMPD forces destroyed the bridge leading to the base, in hopes of slowing down the advancing Covenant forces. This did not, however, stop the incoming dropships, but slowed the advance. The human forces fell back to the base's courtyard, which they defended against waves of Covenant attackers, before falling back into the interior of the main building. Again, they fended off multiple waves of Covenant. They then planted [[M168 Demolition Charge|explosives]] inside the complex, to destroy it in order to prevent the Covenant from accessing the Superintendent's data facility deep under the building. The Marines and the police forces evacuated to the roof, where they were picked up by an [[D77C-NMPD Pelican|NMPD Pelican dropship]]. Once on board, they detonated the explosives and watched as the ONI building was completely destroyed. Six hours later, the building was still burning from the explosions.<ref name="ONIalphasite">''Halo 3: ODST'', campaign level, [[ONI Alpha Site]]</ref>  At the time, the survivors of the siege were unaware that destroying the building had alerted a newly-constructed [[Yanme'e]] hive beneath the building in the Superintendent's data facility, making it much more difficult for UNSC forces to reach the data core later on.<ref name="data">''Halo 3: ODST'', campaign level, [[Data Hive]]</ref>

=====Skirmish at NMPD Headquarters=====
[[File:H3ODST-CrashedD77C.jpg|thumb|left|Dutch, Mickey, and a police officer at the crash site of their D77C-Pelican.|200px]]
While the Alpha Site was destroyed, Edward Buck and his squad's sniper, [[Kojo Agu]], made their way to the top floors of the [[NMPD headquarters]] building, where they were to be picked up by Pelican with two other ODSTs already onboard. However, the dropship was shot down before landing, and it crashed on another rooftop killing the pilot on impact. Buck and Agu fought their way across the rooftops, and eventually reached the crash site, where they fought off waves of attacking Covenant using heavy weapons from the Pelican. Finally, a [[Jiralhanae Chieftain]] dropped off from a [[Type-52 Troop Carrier|Phantom]], killed an NMPD officer and severely wounded Agu. The squad managed to kill the Chieftain, after which they decided to evacuate through the train tunnels which led into Old Mombasa.<ref name="nmpdhq">''Halo 3: ODST'', campaign level, [[NMPD HQ|NMPD HQ]]</ref>

=====Nightfall=====
[[File:H3ODST NewMombasa.jpg|thumb|right|The rainy streets of New Mombasa, reduced to a ghost town.|200px]]
By nightfall, nearly all human forces in the city had either been evacuated or destroyed. Among the few survivors were the members of Buck's ODST squad, who arrived at [[Kikowani Station (location)|Kikowani Station]] near the city's northeastern seawall, only to realize that the station, as well as [[Kikowani|its surroundings]] had been flooded by [[water]], making escape through train tunnels impossible. The squad decided to hijack a Phantom dropship, in which they succeeded. Buck escorted the rest of the squad through the flooded sections of the city in a [[Type-26 Ground Support Aircraft|Banshee]]. The area was filled with Covenant forces, including a [[Type-47B Scarab|Scarab]]. After destroying the Scarab, they managed to fly out of the city, when Buck suddenly realized he knew where Captain Dare was and decided to go back to find her, inside the Superintendent's [[New Mombasa Data Center|data center]]. During the battle, arriving Covenant cruisers began excavating the area around the crater created by the slipspace rupture.<ref name="kikowanistation">''Halo 3: ODST'', campaign level, [[Kikowani Station]]</ref>

Around the same time, a lone ODST only known as "[[the Rookie]]", thought dead by the rest of the squad, woke up in his pod, on the edge of a rooftop in [[Mbaraki]]. The city was already occupied by the Covenant, with no UNSC resistance left. The Superintendent aided the Rookie to survive in the city and look for clues for what happened to his squad. Upon finding objects related to his squad, he envisioned what had happened to them over the course of the day. After wandering around the city for a while, the Rookie received a distress message from Dare, who was inside the Superintendent's data facility deep under the city. He made his way to a subway entrance, and descended down an elevator shaft, to Sublevel 7 of the data center.<ref name="mombasastreets">''Halo 3: ODST'', campaign level, [[Mombasa Streets]]</ref> At this point, the underground tunnels had become infested with [[Yanme'e]], who had built massive hives in the area.{{Ref/Reuse|data}}

=====Extracting the asset=====

[[File:Hurag_encounter.png|thumb|left|250px|Dare and the Rookie meet [[Quick to Adjust]], who "saved" Vergil inside the Superintendent's Data Center.]]
Eventually, the Rookie managed to meet up with Dare inside the [[New Mombasa Data Center|Superintendent's Data Center]]. Inside, they discovered a [[Huragok]] called [[Quick to Adjust]],{{Ref/Reuse|Catalog}} who had combined the Superintendent, namely its [[Vergil]] subroutine, with itself. As Quick disconnected from the core, the AI shut itself down, as all of its data had been transferred into the creature. At this point, Buck arrived into the complex and the ODSTs escaped back to the surface through the tunnels filled with Covenant, while protecting the critically important Huragok.{{Ref/Reuse|data}}

In the final hours of the day, the area was already full of arriving Covenant capital ships. Buck, Dare and the Rookie made their way to the surface, through a Covenant outpost in the city, and eventually took an elevator to the city's [[New Mombasa Waterfront Highway|Waterfront Highway]]. They then pushed through the Highway and made a stand at the entrance to Uplift Reserve. The Phantom captured by the rest of the squad arrived and picked them up, and they made it out just as an assault carrier appeared from slipspace and glassed the area.{{Ref/Reuse|coastal}}

==Aftermath==
[[File:Portal odst.png|thumb|250px|right|The Covenant fleet uncovering the Portal.]]
===New Mombasa and Earth===
Immediately after the occupation, more and more Covenant ships started arriving at Earth. They started uncovering the Forerunner structure which would later be revealed to be [[Portal at Voi|the Portal]] to [[Installation 00|the Ark]].{{Ref/Reuse|coastal}}

The UNSC would not discover the actual purpose of the Covenant's arrival on Earth until two weeks after the [[Battle of Installation 05]]; most of the information was presumably received from the Huragok that had absorbed [[Vergil]]'s data. By this point, the [[Prophet of Truth]] had already arrived in Sol System on the [[Forerunner Dreadnought]] with the remainder of [[Truth's fleet|his fleet]] with him.<ref name="odstepilogue">'''[[Halo 3: ODST]]''', campaign level ''[[Coastal Highway]]''</ref><ref>'''[[Halo 3]]'''</ref> 

The remnants of New Mombasa were liberated after Truth's fleet retreated to [[Installation 00|the Ark]] and were subsequently defeated, with [[Operation: MARSH FLASH]] beginning as part of the [[URNA Southwest Campaign]]. Years after the war's end, a movement known as "[[Project Rebirth]]" emerged to endorse the eventual rebuilding of Mombasa in the aftermath of the War.<ref name="pointprizes">''[[McFarlane Toys/Halo Point Prizes]]'', Campaign Master Chief</ref>

Some of the refugees of the battle ended up on the planet [[Oban]].<ref>'''[[Halo: Envoy]]''', ''Chapter 16''</ref>

===''Solemn Penance'' and UNSC ''In Amber Clad''===
The ''Solemn Penance'' would arrive at [[Installation 05]] on [[2552#November|November 3]], the Prophet of Regret having learned of the ring's location from the [[Luminary]] on [[Meridian]].<ref>'''[[Halo 2: Anniversary]]''' - ''[[Terminal (Halo 2: Anniversary)|Terminal]] "Beholden"''</ref> The assault carrier was followed by ''In Amber Clad'', who deployed a [[First Platoon (ODST)|contingent]] of [[Orbital Drop Shock Troopers|ODSTs]] led by [[John-117]] on a [[Assassination of the Prophet of Regret|mission to capture or kill the Prophet]], an objective they would accomplish.<ref>'''[[Halo 2]]''', campaign level ''[[Delta Halo]]''</ref><ref>'''[[Halo 2]]''', campaign level ''[[Regret (Halo 2 level)|Regret]]''</ref> The ''Coral Sea'', ''Dusk'' and ''Redoubtable'' all arrived as well, but at different times. The last ship to arrive, the ''Dusk'', appeared in time to witness the outbreak of the [[Great Schism]].{{Ref/Reuse|goo22}}

===Alpha-Nine, Vergil, and Sadie Endesha===
Alpha-Nine was assigned to guard Quick to Adjust.<ref>''[[Halo: New Blood]]'', Chapter 9</ref> Eventually, the Huragok was interrogated by Avery Johnson.{{Ref/Reuse|odstepilogue}} A transcript of the interrogation of Vergil was given to [[Terrence Hood]] in a document titled "Vergil".<ref>''Halo Legendary Crate'', Vergil</ref>

A timeline of events in the Battle of Mombasa and the CSV of Edward Buck were compiled for [[Margaret Parangosky]] by [[Black Box]] titled "First Twelve Hours".{{Ref/Reuse|firsttwelvehours}}

===Forerunner glyphs and the Conduit===
In the summer of [[2557]], nearly five years after the battle, the Forerunner glyphs recovered by several ODSTs in the city were finally decoded, pointing to a region on [[Gamma Halo]] containing an [[unidentified Forerunner machine]].{{Ref/Reuse|ope}}

==Trivia==
*The multiplayer levels [[Turf]], [[Terminal (map)|Terminal]], [[District]] in ''Halo 2'' and [[Longshore]] in ''Halo 3'' take place during the Battle of Mombasa. The ''Halo 2'' level [[Tombstone]] apparently takes place late in the battle, (roughly concurrent with ''Halo 3: ODST'') as the city is largely in ruins.
*[[Sadie's Story]] depicts Regret's assault carrier arriving in the city via slipspace. The carrier's descent to the atmosphere is never shown in any other source, but it may have made a short, pinpoint jump to get away from the UNSC forces.
*Judging by the timeline, New Mombasa was supposed to be over a thousand kilometers further south than Old Mombasa due to geographical latitude placement. This could be an oversight by Bungie due to geographical emplacement; by 1900 hours, near the equator line, the sun has already set, while on the level NMPD HQ, at 1936 hours the sun is still setting.{{Ref/Reuse|nmpdhq}}<ref>''Halo Timeline year 2552'', [[2552]]</ref>
