The '''Battle of Trove''' was an engagement fought between the crew of the {{UNSCShip|Spirit of Fire}}, the [[Covenant]], the [[Flood]], and [[Forerunner]] forces on the [[Forerunner]] shield world known as the [[Trove]] during the [[Human-Covenant War]] from [[2531|February 23 to 25, 2531]].<ref>'''[[Halo: The Essential Visual Guide]]''', ''page 174''</ref><ref name="timeline">'''Halo Wars''' ''[[Halo Wars Timeline Events|Timeline Events]]''</ref><ref name="Assembly">'''Halo: Reach''', ''[[Data pads|data pad 15]]''</ref>

==Background==
The [[Trove]] or "Trove" had been discovered by the [[Covenant]] some time prior to the battle,<ref name="OSG">'''[[Halo Wars: Official Strategy Guide]]''', ''page 50''</ref> but despite their reverse-engineering attempts, they had not been able to activate the shield world's most prized artifact: the [[Apex Site]], an installation which contained numerous Forerunner {{Class|Sojourner|dreadnought}}s. With the [[Human-Covenant War]] ongoing, the Covenant started their search for a key to activate the Forerunner ships in order to bring a swifter end to the [[Human|human race]]. After seeing [[Ellen Anders]] activate a [[Relic (location)|Forerunner structure]] on [[Harvest]], the Covenant discovered that [[Reclaimer|they could use a human to activate]] the Apex installation.<ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=96LZ6gGQS5Y&feature=player_embedded "Walk in The Park"]''</ref>

[[Arbiter]] [[Ripa 'Moramee]] captured Professor Anders after the [[Battle of Arcadia]], planning to use her to activate the Forerunner dreadnoughts' systems. The UNSC ''Spirit of Fire'' pursued the Covenant to the shield world without reinforcements to rescue Anders.<ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=yAwbJN6DzL4&feature=player_embedded "She is Not My Girlfriend"]''</ref> Upon entering the system they followed Anders' transponder signal the best that they could. Captain Cutter launched several Marine teams, as well as [[Sergeant]] [[John Forge]] to begin surface operations to locate Professor Anders.<ref name="signal">'''[[Halo Wars]]''' campaign level, ''[[Anders' Signal]]''</ref>

==The battle==
===Initial actions===
Recon Teams [[Recon Team Echo|Echo]] and [[Recon Team India|India]] deployed on the shield world's surface, along with a small force led by Forge. Using [[M312 Heavy Recovery Vehicle|Elephants]] and Marine infantry, together with [[carpet bombing|air support]] from [[B-65 Shortsword|Shortsword]] bombers and help from SPARTAN [[Red Team]], Forge's force cleared an area of [[Jiralhanae]] around a beacon, awaiting the arrival of reinforcements and the Recon Teams.{{Ref/Reuse|signal}}

===First encounter===
Shortly after this, however, the force received an ominous message from Echo Team, stating that they were under attack from "[[Flood|things]]," before dropping out of contact. India Team sent a similar message before dropping out of contact.{{Ref/Reuse|signal}}

Forge's team and the Spartans moved to investigate, encountering the Flood for the first time, including dozens of [[Pod infector|infection forms]] that resulted in a large number of Marines being lost. However, they successfully recovered both teams' Elephants and retreated back to the [[Firebase]] being constructed at the beacon site.{{Ref/Reuse|signal}} UNSC forces began to have problems with air transport, as the exterior surface's atmosphere was thick with dust, which caused the engines on [[D77-TC Pelican|Pelican dropships]] to fail within three flights.{{Ref/Reuse|timeline}}

Red Team discovered that a [[proto-Gravemind]] was coordinating the Flood forces and was also jamming Anders' transponder signal. However, before they could destroy the Gravemind, their [[M12 Force Application Vehicle|Warthog]] was overturned and they had to be rescued by Forge's Marines. After contending with [[Flood swarm]]s and [[Flood thrasher form|Thrasher Forms]], the Marines were able to rescue the Spartans and destroy the proto-Gravemind.<ref>'''Halo Wars''' campaign level, ''[[The Flood (level)|The Flood]]''</ref>

===Descent===
[[File:ShieldWorldOpening.png|thumb|250px|The ''Spirit of Fire'' being pulled into the Shield World.]]
After destroying the proto-Gravemind, the ''Spirit of Fire's'' AI [[Serina]] located Anders' signal, which was apparently in the middle of an ocean. While the ''Spirit'' was hovering over the sea, the doors of a huge submerged entry into the planet opened and several [[Forerunner]] [[Sentinel]]s flew out. The ''Spirit of Fire'' became locked into a powerful docking mechanism and inevitably began a controlled 'fall' into the rift.<ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=z0dXxJaGbPM&feature=player_embedded "Open Sesame Part Two"]''</ref>
The remaining UNSC forces on the Shield World's surface, composed of [[Alpha Platoon]], [[Bravo Platoon]], and [[Charlie Platoon]], had less than twenty minutes to fight their way past hundreds of Flood forms before being airlifted back to the ''Spirit of Fire''. [[Flood swarm]]s made air support almost useless, forcing the Marines to use large numbers of [[M9 Main Anti-Aircraft Tank|Wolverines]] to clear the air before tanks and infantry could clear landing zones of Flood growths. They managed to slow down the ''Spirit of Fire's'' descent by disabling Forerunner pylon towers powering the docking system with [[XRP12 Gremlin]]s, giving them a little longer. After evacuating the first two platoons, the team had to escort the final platoon back to the firebase for extraction after their [[D77-TC Pelican|Pelican]] was forced to abort its run. After extracting all UNSC forces, the firebase was abandoned to the Flood and the ''Spirit of Fire'' began her descent.<ref>'''Halo Wars''' campaign level, ''[[Shield World (level)|Shield World]]''</ref><ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=RKbH5aXZgbw&feature=player_embedded "Descent"]''</ref>

Fighting their way down through a service conduit inside the Shield World, the ''Spirit of Fire'' was attacked by even more Flood forms. Flood growths began to sprout on the ship's hull, and Marines and aircraft were forced to fight on the hull of the ship to remove the Flood forms. Furthermore, [[Sentinel]]s attacked the Flood, and while they initially provided some support to the UNSC, after passing through the first decontamination ring, the Sentinels identified them as possible infection vectors and relabeled them as targets. The UNSC forces managed to clear the hull of growths, removing the Flood and thus allowing the Sentinels to withdraw.<ref>'''Halo Wars''' campaign level, ''[[Cleansing]]''</ref> After this, the ''Spirit of Fire'' accelerated out of the tunnel, and emerged into the interior of the Shield World.<ref name="freefall">'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=YcczaSAH4lU&feature=player_embedded "Freefall"]''</ref>

===Interior===
{{Quote|The Ancients have granted us the power to doom your race. Let the deconstruction of our gifts begin! The majesty of our new fleet will be unparalleled!|The Arbiter to Anders.<ref name="judgement">'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=iXZbTCmSeSI&feature=player_embedded "Judgement Day"]''</ref>}}
In the inner [[Dyson sphere]] of the Shield World, the ''Spirit of Fire'' immediately entered a collision course with the Covenant destroyer ''[[Proclamation's Tithe]]''. Despite hard course corrections, the two ships impacted, with a large section of the ''Spirit'' being violently sheared off.{{Ref/Reuse|freefall}} The collision also destroyed half of the ''Spirit''{{'}}s complement of [[D20 Heron]]s. Dozens of Marines, vehicles, and aircraft were deployed onto the ''Spirit''{{'}}s hull to fend off boarding parties who were trying to prevent technicians in [[Cyclops]] exoskeletons from repairing the ship's power core, while at the same time the ship was raked by [[plasma]] fire. Escaping from the destroyer, the ''Spirit''{{'}}s AI, [[Serina]], detected Anders' signal.<ref>'''Halo Wars''' campaign level, ''[[Repairs]]''</ref> Sergeant Forge, along with other forces, were deployed to the signal's apparent source on the Shield World's inner surface.{{Ref/Reuse|judgement}}

Imprisoned in the Apex, Anders was forced by the Arbiter to activate the ancient artifact, powering up its fleet of {{Class|Sojourner|dreadnought}}s. In their religious fervor, her guards were distracted and Anders used a [[teleporter]] to return to the surface, where she was rescued by Forge.{{Ref/Reuse|judgement}} Anders was then evacuated back to the ''Spirit'', while Sergeant Forge and Spartan [[Red Team]] proceeded to lock the area down, for a safe place to the ''Spirit'' to put down. Anders theorized that they would have to capture four base sites to begin an effective resistance. Through the use of armor, air support, and a [[Deutoros-pattern Scarab|Scarab]] captured by a Spartan, the UNSC captured the bases and prepared to attack the Apex itself.<ref>'''Halo Wars''' campaign level, ''[[Beachhead (Halo Wars level)|Beachhead]]''</ref>

On the ''Spirit of Fire'', Anders devised a plan to stop the Covenant from using the Forerunner ships. The UNSC forces would have to sacrifice the ''Spirit''{{'}}s [[Shaw-Fujikawa Translight Engine]] to create an explosion so powerful, it would collapse the miniature [[Astroengineering#Stars|artificial star]] inside the Shield World, completely obliterating the installation, though it meant that they would have no way to return home.<ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=8GAyuG2g_Cg&feature=player_embedded "I doomed Humanity"]''</ref> To accomplish this, they would need to assault the Apex Site and use an [[elevator]] on the main platform, to take the slipspace drive right into the star.<ref name="reactor">'''Halo Wars''' campaign level, ''[[Reactor (Halo Wars level)|Reactor]]''</ref>

===Assault on the Apex===
When the UNSC forces had secured the area, the ''Spirit'' put down close to the surface, to deliver Slipspace drive to the ground. It was attached to two [[D77-TC Pelican|Pelicans]], which were to be used to transport it to the Apex main platform. On their way however, they were shot down, just under a towering hill comprised of a series of ramps, on top of which there was a teleporter which led to the Apex's control center.{{Ref/Reuse|reactor}}

After an attempt at airlifting the drive failed, the mission was changed into a ground operation, with the intent of using an [[M312 Elephant]] to tow the reactor to the [[teleporter]] on the top of the hill, which was full of Covenant and Flood forces. The UNSC established a [[firebase]] on the bottom of the hill, and gradually ascended the towering hill up to the Apex Base Site, meeting determined resistance from the Covenant. They eventually reached a [[Slipspace translocation|teleporter]] that took [[John Forge|Sergeant John Forge]], a Marine lieutenant, and Red Team to the Apex's control center with the slipspace drive.{{Ref/Reuse|reactor}}

[[File:Hw-prima-blog-04-01.jpg|thumb|250px|Red Team ready for combat at the Apex.]]
Upon arriving at the Apex Site's control center, the lieutenant, Forge and the Red Team proceeded with the mission. The lieutenant went to open the door of the elevator, Forge started to unload the reactor from its transport, while the Red Team guarded them. However, the Arbiter, who had previously been [[Active camouflage|cloaked]], appeared and killed the lieutenant just after the latter had activated the lift to the inner star. Simultaneously, multiple [[Sangheili]] warriors emerged from cloaking from the other end of the platform and charged the Spartans. Forge decided to take on the Arbiter himself, while the Red Team would hold off the Elites.<ref name="monsters">'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=nlNHT57SbkA&feature=player_embedded "Monsters"]''</ref>

Forge released the locks holding the FTL drive on to the trailer, causing it to slide at the Arbiter. The Spartans engaged the Honor Guards in frantic and acrobatic close combat, dispatching them with ease. The Arbiter was gaining the upper hand in the duel with Forge, but the sergeant managed to take advantage of his opponent's hubris, wounding him with a combat knife and delivering a killing blow to the Arbiter with his own [[Type-1 Energy Weapon/Sword|energy sword]].{{Ref/Reuse|monsters}}

After the duel, the Arbiter's body was pushed off the platform, and the reactor was loaded onto the elevator. The reactor had already started overheating and could no longer be detonated remotely, leaving manual detonation as the only option. [[Jerome-092]] offered to activate the reactor, sacrificing himself. Forge declined, saying that the UNSC would need every last Spartan left in the fight. Jerome agreed, commenting on the honor of serving with Forge. Forge began his ascent to the star, while the Red Team reported back to the ''Spirit of Fire''.{{Ref/Reuse|monsters}}

===Escape===
[[File:ShieldWorldDestruction2.png|thumb|The destruction of the Shield World.]]

The UNSC forces located one of the shield world's exit portals, but Serina found that the portal had been sealed off. Red Team and groups of Marines had to deal with massive Covenant and [[Flood]] resistance before they could disengage the [[door interlock]]s. Using tanks, [[AC-220 Vulture|Vultures]], [[carpet bombing]], [[cryo bomb]]s, and [[Magnetic Accelerator Cannon#MAC Blast|orbital bombardment]] to destroy the Covenant and Flood bases, they successfully opened the doors.<ref>'''Halo Wars''' campaign level, ''[[Escape (Halo Wars level)|Escape]]''</ref>

As the sun slowly went supernova, the ''Spirit of Fire'' was caught in its increasing [[Gravity well (physics)|gravity well]]. By performing a gravitational slingshot maneuver around the sun, the ''Spirit'' was able to break away from the gravity well and escape through the portal, and far enough from the Shield World not to be caught in the supernova's blast radius. Moments after the ''Spirit of Fire'' escaped from the planet, it exploded, destroying Trove and all Covenant and Flood forces upon its surface.<ref>'''Halo Wars''' ''cutscene [http://www.youtube.com/watch?v=Rw449I95UHY&feature=player_embedded "One Less Sun in The Universe"]''</ref>

==Aftermath==
With no ability to enter [[Slipstream space]], and the journey back to UNSC space likely to take years, if not decades, the ''Spirit of Fire's'' crew went into [[Cryo chamber|cryostasis]]. The UNSC [[Office of Naval Intelligence]] declared the ''Spirit'' and crew to be [[missing in action]]. In [[2534]], the ''Spirit of Fire'' was declared to be "lost with all hands" by the UNSC. The reason for this change was kept top secret. A memorial service was held for the people aboard the vessel, but many of the crew's family members chose not to attend, holding out hope that their loved ones are still alive.{{Ref/Reuse|timeline}} The ship would not make contact with the outside world until [[2559]], when it was unexpectedly transported to [[Installation 00]].<ref>'''Halo Wars 2''', campaign level ''[[The Signal]]''</ref>

The [[The Assembly|Assembly]], having intercepted transmissions from the [[proselytization network]], noted the presence of the Flood as a "third variable". Due to the third participant being a terrifying opponent to the Covenant, the [[Assembly Minority]] suggested the possibility of forming an association - even a union - with it. However, due to the risks involved, the Assembly chose not to attempt contact with the Flood.{{Ref/Reuse|Assembly}}

In early [[2557]], nearly twenty-six years after the shield world's destruction, the ''[[Ace of Spades]]'', a [[salvager]] vessel captained by Sergeant John Forge's daughter [[Rion Forge]], visited the debris field and recovered [[Little Bit|a fragment]] of the shield world's custodian AI.<ref>'''Halo: Smoke and Shadow'''</ref> Several months later, ONI conducted a [[Mission to the Korinth Prior system|mission]] within its debris field to search for evidence of the ''Spirit of Fire'',<ref>'''[[Halo Legendary Crate]]''', ''[[Halo Legendary Crate/Data Drops|Data Drop #4]]''</ref> having learned of it from data stolen from the ''Ace of Spades''. Shortly after the ''Ace of Spades'' was returned to the debris field by [[343 Guilty Spark]], a massive UNSC fleet emerged from slipspace and nuked the debris field. The nuclear bombardment was expected to blow the field to bits and disrupt its orbit around the system's star. Anything that survived would most likely be pulled into the star's gravity well and destroyed, completely eradicating the remnants of Trove.<ref>'''[[Halo: Renegades]]'''</ref>
