Battle of Corellia

The Sith Empire's invasion of the planet Corellia was carefully planned over a number of years by the Sith Lord Darth Decimus during the Cold War between the Empire and the Galactic Republic. Agents of Imperial Intelligence identified potential turncoats in the highest levels of the planet's government and secretly recruited them, promising the politicians lifetime power in return for loyalty, and the Empire soon had almost the entirety of the planet's ruling Corellian Council in its pocket. Darbin Sull, one of the youngest individuals ever elected to the council, was quick to pledge loyalty to the Empire when they promised him the position of prime minister in return—something they refrained from informing the current Imperial-allied prime minister, Cal Falcone. Councilor Belos agreed to aid the Empire out of a belief that their superior military might would inevitably overwhelm the Republic, while Councilor Caicos used a combination of bribes, blackmail, and threats to convince the other council members to back the Empire when the Imperial admiral known as the Voidwolf called in a debt. The First Son of the Sith Emperor helped convince the Council to join the Empire by revealing his identity as Syo Bakarn, a Jedi Master and member of the Jedi Council, to Secretary Nadien as an example of his power.

Around 3642 BBY, the tenuous peace brought by Treaty of Coruscant shattered under the stress of multiple conflicts, both internal and external, amongst the Republic and the Empire. Seeing an opening, Decimus put his plans in motion: Imperial Intelligence agents attempted to infiltrate the offices of the Corellian Engineering Corporation in order to seize control of the complex's powerful defense systems and halt any possible resistance. However, Intelligence's operatives disappeared after entering the offices, and CEC's defenses remained under the corporation's control when Decimus ordered the invasion to proceed as planned around 3640 BBY. Launching a fleet from the heart of the Empire, he signaled the Corellian Council to make their move. The politicians declared a fake emergency that cleared all hyperlanes into the Corellian system, shut down the planet's spaceports, and convened in the Government District of Coronet City for a meeting. There, the Council unanimously voted to submit to Imperial control just as Darth Decimus's fleet arrived above the capital city.

While the Corellian Council capitulated to the Empire, Decimus's forces attempted to conquer the planet anyway as a show of force. All communications were immediately cut, leaving the Republic unaware of the Imperial invasion. An initial attack on the capital of Coronet City shattered sections of the fabled Coronet Zoo, releasing alien wildlife into the streets of the city. One of the Empire's primary targets was the district known as the Incorporation Islands. A series of towers occupied by Corellia's largest corporate entities, the sector quickly became a battleground as corporate security forces fought back against the Empire aided by armies of droids.

The Bastion, a massive military complex in Coronet City, was a stronghold of resistance that served as the center of operations for the entire Republic military. Therefore, it was a prime target for Imperial conquest in the eyes of General Arkos Rakton, and part of the Imperial invasion involved the reformation of an elite black ops team under the command of Lieutenant Pierce. Pierce's unit, including Captain Lorant, Sergeant Arlos, Lieutenant Tanido, and several other soldiers, infiltrated a Republic shuttle carrying reinforcements to the Bastion mere hours before Darth Decimus's forces arrived in-system, and the team had complete control of the complex a few hours later. Axial Park was the target of an Imperial force led by the Sith Emperor's own personal Guard, and the captured Museum Republica quickly became an Imperial base of operations in the park. One of the city's high-rise towers was clipped by a damaged Imperial warship, and the near-collapse of the structure killed the founder of the Beharen Droid Factory. Fortunately for the Republic, Syo Bakarn was able to fortify several buildings known as Guardian Holds with elite Republic troops, munition stores, bunkers, and other military assets, and the Holds withstood all Imperial attacks through the long invasion. However, the First Son used his identity of Bakarn to place several Children of the Emperor within the Holds.

However, the Corellians were not a culture to submit to Imperial dominance so quickly. As Darth Decimus made his headquarters in the offices of Corellia's Trade Tariff Service at the advice of his lieutenant, Moff Tarandon, the Corellian Security Force immediately realized it would not survive an all-out war with the invaders. Therefore, CorSec commissioner Jonah Carter and his lieutenants sent out a panic alert to all officers, sending them underground, and began to prepare for war. However, some CorSec officers, like Raddus Venn, willingly submitted to the Empire and began to aid the planet's new rulers. Coronet Durasteel immediately joined the Empire at the beginning of the invasion, and it was followed by corporations like Horizon Enterprises, led by its Senior Executive President Erin Kaldo. However, while the Board of Directors and the rest of the company's upper management were willing to work with the Empire, Horizon's workforce had begun to rebel the moment they learned the Empire arrived. Kaldo and the directors were forced to call in Imperial help to "reduce" the workforce, hoping that the elimination of a number of workers would convince the others to see reason and submit to Imperial rule.

Normal citizens began to band together with freighter crews and unemployed mercenaries in an effort to strike back against their new rulers, and with coordination and training by CorSec the rebels proved highly successful in the early days of the occupation. Over a dozen high-ranking Imperial officers were assassinated, and the group bombed many of the shipyards that the Empire was using as landing pads; rebels would often pretend to cooperate with the invaders in order to access Imperial bases and wreak havoc. A major target of the Empire's first strikes was the enclave of the Green Jedi, a group of Corellian Jedi who wore green cloaks to symbolize the fact that they valued their loyalty to their native world over that of the Republic. A first attempt to bombard the structure was halted by the Enclave's powerful shields, powered by internal reactors, and the Green Jedi quickly erected offensive weapons emplacements. The Imperial warship sent to attack the Enclave a second time was shot down by the base's defenses, and the section of the vessel that did strike the structure failed to weaken it or inflict heavy casualties. The Green Jedi's leader, Arfan Ramos, quickly allied with the resistance and the group began aiding their fellow Corellians in the fight against the Empire.

Another stronghold of resistance was the CorSec Maximum Security Prison. CorSec forces under the command of Wolroff had secured the facility for use as a staging area for attacking the Empire, and many of the prisoners had agreed to aid the police in exchange for a shortened sentence. However, the Empire had gained intelligence on the prison's extensive security systems from a captured program—the systems now ignored CorSec personnel and only attacked Imperial forces, but an assault team could reprogram the systems at certain control nodes. This covert assault was successful in their mission, causing the prison security systems to inflict heavy enough losses to drive out the CorSec presence, and the unit also managed to eliminate Wolroff in the process.

Despite small errors, the Imperial invasion was progressing almost perfectly until rebels knocked out Coronet City's rocket tram system, which the invaders had been using to quickly move their troops. The Corellian Engineering Corporation targeted the trams with ion weaponry, freezing the invasion and stranding different sections of the Imperial forces across the city. Fighting soon began to erupt in the Incorporation Islands as powerful companies began aiding those Corellians who resisted the Empire.

Upon learning of the situation with the rocket trams, Darth Decimus ordered his subordinate Darth Charnus to rectify the problem. At the Sith Lord's directive, Imperial operatives struck a blow against the Czerka Corporation by eliminating several of its weapon caches in the Incorporation Islands as part of an operation to seize the company's hull-cracker explosive weapon. Charnus continued to direct operations from orbit aboard his flagship, the Tears of Taris, and directed a strike force to aid Commander Jastal at Imperial Outpost Alpha in the Imperial Guard's attempt to retrieve the hull-cracker. After retrieving the codes for the weapon from the Czerka employee Brall Tavar, the strike team seized the hull-cracker and prepared to use it against the Corellian Engineering Corporation.

By disabling two of CEC's signal towers, the Imperial operatives shut down the corporation's massive army of security droids, and Commander Jastal initiated his siege of the CEC complex. A CEC employee by the name of Benton Maas desperately attempted to save himself by offering the Empire access to the complex's back door in exchange for safety, but Charnus's forces chose to continue the original plan—blasting through the building's main door with the hull-cracker. Commander Krade and Charnus's forces defended Imperial explosives experts while they planted charges, and the Sith Lord's operatives stormed the company board room itself. After defeating the prototype C-9X droid sent by Maas, the Imperial forces killed the CEC board and overloaded the ion cannons targeting the rocket trams.

A major rebel assault on the occupation forces was averted when the Imperial agent Hazeen, who had infiltrated the resistance, managed to alert other Imperials through the probe droid G-05 to the rebels' dead drops of intel and thereby put a stop to the attack. As they had in several other regions, the Empire offered bounties on groups of rebel saboteurs in the Incorporation Islands when the resistance members became especially troublesome. When Raddus Venn learned that groups of heavily-armed CorSec officers were still resisting Imperial control in the Incorporation Islands, he helped an Imperial strike team draw out and kill several of them, hoping that his former comrades would see reason and surrender to Imperial rule. However, CorSec continued to resist—an elite CorSec unit gained access to high-grade explosives and used them to bomb Incorporation Spaceport, destroying an entire squadron of Imperial transports and forcing the Empire to use the nearby Coronet Spaceport instead. An Imperial squad under Randun Ard were ordered by Junia Tavrak to eliminate the CorSec officers, but when the squad failed Tavrak was forced to enlist the help of other agents of the Empire in order to stop an attack on Coronet Spaceport.

A group of Drall—a species native to the planet of the same name in the Corellian system—under the leadership of a Drall named Aerowynn resisted initial attempts by Lieutenant Veet's squad to take their weapons factory, but further attacks by the Empire allowed the invaders to successfully take control of the explosive mines and munitions stored in the factory. A unit under Captain Helricks encountered a group of Wookiee factory workers within the magnogravitics plant in the Labor Valley. The Wookiees quickly decimated the squad, and Helricks was forced to retreat and seek help from other Imperial operatives. Despite their size and ferocity, the Wookiees eventually fell in battle, and the Imperials gained control of most of the planet's industry.

When the Republic finally restored communications with Corellia and learned of the situation there, they immediately mobilized a significant military force to aid the besieged planet. Arriving on the planet, the military under General Aves quickly established a foothold at the Shipwright Auxiliary Spaceport in Coronet's Blastfield Shipyards and withstood all Imperial attempts to force them off the planet. Before long, the shipyards served as the main entry point for Republic forces, and their presence survived the numerous bombing runs made by the Imperials across the sector. The Empire established its own foothold in the area by seizing the Coronet Shipping trade hub, destroying the main ground approach to the facility's landing pads and maintaining constant aerial patrols to dissuade Republic assault shuttles. The Imperials also restricted Republic troop movements when they began use modified neutron emitters to blockade the Blastfield Shipyards. The emitters, which were targeted at the rocket trams and killed all organic lifeforms aboard, deadlocked Aves's forces and prevented him from moving any large detachments to most of Coronet other than Axial Park.

However, fighting with the resistance primarily spilled over into the Labor Valley region, where Imperial forces under Major Tradik fought rebel guerrillas amidst burning factories and devastated structures. As the fighting increased across Corellia, arms dealers came to the planet in order to ply their trade to the occupation forces. One of these arms dealers, Jerris Rez, set up shop in the Labor Valley and began to supply military-grade ordnance and other weapons to Major Tradik. However, when groups of Wookiees, Drall, and Selonians began to attack his shipments, Rez hired several mercenaries to eliminate the aliens in exchange for some of his stock. Corellia StarDrive, a hyperdrive manufacturer, began to funnel credits and supplies to the resistance, but the Empire soon learned of this and had Captain Corgan Sturm's troops detonate explosives throughout the company's complex. The Republic forces aiding StarDrive were killed in the explosion, and the company's buildings were reduced to rubble.

What few Republic forces that could get through to Axial Park soon managed to gain a foothold, and both the Empire and the Republic quickly erected shield generators and weapons emplacements to secure the region. Fighting also spilled over into the Government District, and a Republic command center was established in the Drall Library as the resistance and military besieged the Legislature building. The heavy fighting for Axial Park soon came to be called the "Battle of Axial Park" by the natives, as both the Republic and the Empire deployed significant portions of their forces and their military hardware to the fight for control of the region.

In response to continued resistance in the Labor Valley region, the Empire bombed several factories known to harbor Corellian rebels. However, many Corellians escaped the attack and were aided by Republic doctors, and the Sith Lord Velash ordered the execution of the survivors as a warning to the resistance. The Empire also began to offer a bounty on rebel Selonians in an effort to cull the aliens' numbers. Tradik's forces gained significant ground against the resistance when information from Councilor Sull allowed the Imperials to destroy several of the rebels' supply stores, striking a heavy blow against the Corellians. However, the resistance forces fled into the Selonian tunnel network underneath Coronet, forcing an Imperial strike team to follow and eliminate the Selonian den mother Murthil and her warriors. As the resistance began to draw back from the region, Lieutenant Bregor ordered attacks on several of the rebels' remaining supply caches in order to deprive the Corellians of further resources in the fighting.

The forces under Generals Hesker and Adele Konya in Axial Park were forced to defend against Republic infiltrators when their turrets came under attack, and the Republic quickly deployed jump troopers, walkers, commandos, and artillery batteries in an effort to maintain their foothold in the area. Ambushes by Green Jedi soon became common in the park, and mercenary teams hired by the Empire to eliminate the ambushers failed repeatedly until the alien Grud enlisted the help of Imperial operatives. After drawing out the ambushers near the park's rocket tram tunnels, the Imperials overwhelmed the Green Jedi and ended the threat they posed. The Republic employed its elite rocket-jumpers as another method of ambushing Imperial forces, but the alien Thadd convinced Imperial squads to move the rocket-jumpers' landing beacons, drawing the Republic soldiers into ambushes themselves. When an Imperial weapons transport was shot down over the park, Lord Karvus led a munitions recovery team to retrieve the craft's newly designed high-yield explosives, but Republic forces ambushed the unit. Lieutenant Ogden, the squad's only survivor, was forced to seek help from other Sith and Imperials in the area in order to recover the bombs before the Republic.

As fighting in Axial Park reached its height, the Republic released several jaggalors from the Coronet Zoo upon the advancing Imperials. Despite the protests of zoo staff, Lieutenant Boonan's men exterminated the rare Corellian predators in order to end the threat they posed. When a Selonian warren in Axial Park began to threaten the Imperial occupation forces there, Lord Kanno's forces invaded their den and eradicated the natives. General Dane's position in Axial Park was threatened when the Republic began to deploy sapper droids against the shield generators protecting the Imperial Garrison there. Fortunately for the Empire, a combined Imperial and Sith offensive drove back the Republic troops from the generators, and the Imperial Garrison remained secure against the Republic. Hesker's forces eventually managed to push back the enemy into their command center, where an elite strike force stormed the compound and eliminated the Republic commander Jedi Master Corin Tok and his apprentices, killing many Republic wounded in the process. The loss of Tok was a grievous blow to the Republic presence in Axial Park, and they were forced to retreat from the region and regroup.

When the Sith Lord Darth Tormen learned of the Corellian resistance to the occupation, he transferred his forces under General Krau from the recently conquered planet Rabaan to Corellia. He also utilized a bounty hunter, who had been publicly disgraced and criminalized by Supreme Chancellor Dorian Janarus and the Jedi Master Jun Seros, to advance the Imperial cause on the embattled Core World. Tormen intended to crush the Corellian resistance before the Republic could marshal a full military response, which would force the Republic to recognize a treaty declaring Corellia an official subject of the Empire, and therefore draw out the Chancellor so that the bounty hunter could eliminate him.

On Corellia, the hunter was employed by Tormen to capture several influential leaders of the rebellion so that the Empire could force them to publicly surrender. Working with Tormen's forces, the mercenary successfully captured Chairman Harlon Fane of the Corellian Corporate Council from his stronghold in the executive offices of the Corporate Council's tower in the Incorporation Islands. The bounty hunter also captured the Selonian Shrona Bel-Il, a raider who was aiding the resistance in breaking the Imperial lines, and delivered her to Tormen in the Sith Lord's headquarters in Axial Park. Tormen's third assignment was to capture Commissioner Carter from the CorSec Headquarters itself, and Prime Minister Falcone broadcast the trio's surrender from the Grand Assembly of the Legislature Building itself. To Falcone's surprise, Tormen killed the Prime Minister immediately after the address as punishment for allowing the Corellian resistance to take shape.

Tormen's plan worked perfectly—the Republic responded to the surrender by mobilizing a fleet to the Corellian system that included the Supreme Chancellor's personal Valor-class cruiser Founder. In the midst of the renewed fighting, the bounty hunter's enemy Jun Seros—the Jedi Order's own renowned battlemaster—landed a small force of Jedi in the Green Gardens outside of the Green Jedi Enclave, intending to lead the Green Jedi against the Empire in concert with the Republic's planned offensives. However, the hunter infiltrated Seros's headquarters and killed the experienced Jedi Master before he could complete his preparations. Not long after Janarus arrived in the Corellian system, he and Jedi Master Syo Bakarn learned that an Imperial fleet composed of over thirty troop transports, carrying thousands of reinforcements, was on its way to Corellia, led by a dreadnaught named the Javelin. Fortunately for the Republic, the Javelin was captured by a strike team led by the Jedi Master who held the title of Barsen'thor, or Warden of the Order.

However, Tormen detected the Chancellor's transmission and gave the bounty hunter the assignment of assassinating Janarus himself. While the Founder was still in orbit, the hunter traveled to the Corellia Orbital Station, fought the security and stole an unmarked starship, the Firewing, from a group of smugglers. Pursued by Imperial fighters, the bounty hunter gained access to the Founder using a fake emergency signal. Once inside the Republic cruiser, the hunter battled the security forces and destroyed every shuttles and escape pods in order to ensure that the Supreme Chancellor has no means of escape. The hunter then cut a path through the Supreme Guard and finally confronted the Supreme Chancellor. Although the chief of state was sincerely willing to grant amnesty to the bounty hunter, the latter killed Janarus as ordered. The bounty hunter eventually escaped the cruiser and returned to Darth Tormen's flagship, the Harrower-class dreadnought Tyrant, that was leading the assault against the Founder.

The loss of Janarus dealt a great political blow to the Republic, but in the days that followed his assassination the battle for Corellia continued. Leontyne Saresh, the former governor of the resettlement initiative on the ruined world of Taris, was elected as Supreme Chancellor, and she continued to send resources and men to aid the Corellian resistance. The Barsen'thor, meanwhile, traveled to Corellia to recover one of the members of the Javelin strike team, who had been ejected in an escape pod that had crashed in the Blastfield Shipyards. The Jedi Consular was engaged in a hunt for the mysterious Children of the Emperor, and the companion who had crashed had managed to recover data vital to the search from the Javelins computers before ejection.

Furious that Darth Tormen was stealing his moment of triumph, Darth Decimus began making plans to personally lead an elite force of Sith and Imperial operatives in an assault against the Green Jedi Enclave. After his agents defeated a team of Republic commandos and the Jedi Master Bedoch in the Republic Foundation Museum in order to recover the Enclave's access codes, Decimus's forces and a team of Imperial Guards under General Hesker's leadership stormed the structure and fought a brutal battle against the army of Green Jedi within. Within the Enclave, the Sith forces killed Master Arfan Ramos and the other members of the Green Jedi Council in a battle in the Council's chamber, and Decimus's agents eliminated Darbin Sull since the man had outlived his usefulness. After taking the Green Jedi enclave, the Imperials established a garrison in the structure, but the Republic employed stealth troopers in an attempt to drive out the invaders. The Imperial tech specialist Shorn determined that the Republic was utilizing an incredibly advanced cloaking technology, but managed to modify a stealth field generator to disrupt other fields. As a result, Imperial forces were able to strip the stealth troopers' advantages, leveling the playing field and allowing the more numerous Imperials to secure their control of the enclave.

During the fighting in the Government District, Captain Zender's unit managed to corner a sizable resistance force, but the rebels managed to construct several repeating blasters to halt the Imperial advance. However, Zender's forces were able to overwhelm the rebel defenses with the aid of Sith and Imperial operatives, and significantly reduced the resistance's numbers in the area. Admiral Hestun enlisted the help of an Imperial strike team to target the Republic's anti-air defenses so that his fleet could bombard the emplacements, as Hestun was not permitted to bomb the entire sector—the Emperor himself wanted the Legislature intact. The team was successful in its mission, allowing Hestun to accurately target the emplacements, but the Republic would retain a foothold in the Drall Library despite their loss.

The Republic was able to establish an encampment in the Coronet Arms Hotel near the Legislature, and after repeated Imperial assaults failed to dislodge them the Sith Lord Malichose was personally selected by Darth Decimus to rectify the situation. Malichose's operatives stormed the hotel, massacring the Republic troopers and resistance members inside before destroying the heavy artillery set up there. The Imperial Ministry of War also offered bounties on Green Jedi after an enclave was discovered in the Government District, in an effort to thin the ranks of the native Jedi. Captured Green Jedi were brought to interrogation expert Emma Thex, but she was forced to employ the aid of other Imperial operatives in order to recover CorSec interrogation droids from a Republic storage facility when her captives proved resilient.

As the conflict escalated, certain high-ranking Sith Lords decided to take advantage of the chaos to pursue their own ends. Darth Baras, who was attempting to declare himself Voice of the Emperor, had tried to kill his apprentice in order to silence the younger Sith. Baras's apprentice had been appointed to the position of Emperor's Wrath by the servants of the Emperor, and the Emperor's Hand had ordered the Sith to protect the Dark Councilor Darth Darth Vowrawn from Baras's assassins on Corellia. The Wrath foiled several assassins in the Incorporation Islands before making contact with Vowrawn in the elder Sith's base within one of the nearby towers. Allying with Vowrawn, the Wrath began to target Baras's subordinates on Corellia, starting with Colonel Senks, a spy planted in the Corellian resistance. After killing the spy in a resistance stronghold located in the Labor Valley, the Wrath exposed the traitorous Jedi Master Injaye to her comrades Rubatin, Tatham, and Joce before killing all four of the Jedi in their secret bunker. The Sith Warrior's final actions against Baras involved storming the Sith Lord's secret base on the planet, defeating Baras's servant Lord Draahg and releasing the mysterious Entity the elder Sith used to gain visions of the future.

Around the same time, the Dark Councilor Darth Thanaton declared a Kaggath—an ancient Sith rite that involved a battle between two Sith and their power bases—against a young Sith Lord named Kallig, and declared Corellia to be their battlefield. On Corellia, Kallig's first strike was to kill Thanaton's apprentice Lord Skar in the Incorporation Islands, and Thanaton responded by trying to destroy a fuel refinery needed to refuel Kallig's fleet. Thanaton briefly confronted the younger Sith as Kallig raced to disarm the explosives in the refinery, but instead of fighting he sprung a trap that would have destroyed the structure with a series of explosions if Kallig had not shut down the refinery.

Seeking to claim victory, Kallig enlisted the help of Major Ilun's forces after defeating a Republic strike force in Axial Park, and with the support of Ilun's troops the Sith Inquisitor stormed Thanaton's headquarters in the Museum of Corellian Industry. After destroying the DP-6 Guard Droid Thanaton left to defend his headquarters, Kallig deactivated the museum's shields so that Moff Valion Pyron and the Inquisitor's fleet could bombard the structure. However, Thanaton took advantage of his opponent's absence to attack Moff Pyron's headquarters in Capitol Square, forcing Kallig to defend the Moff before meeting the elder Sith for a final duel. But instead of facing Kallig himself, Thanaton first unleashed his subordinate Darth Kallous and cyborg soldiers upon his opponent, and when Kallig succeeded in defeating Thanaton in combat the Dark Councilor fled the planet. Fleeing to Korriban to seek aid from the Dark Council, Thanaton was pursued by Kallig, who fought and killed him in a final confrontation in the Council chambers.

After his victories in Axial Park and the Government District, Darth Decimus soon turned his attention to the continued Republic presence in the Blastfield Shipyards, and his forces began to press the offensive against their trapped opponents. Several bombing runs were attempted, but the Republic's anti-aircraft emplacements in the region soon forced the Empire to switch to a more conventional ground assault. An Imperial transport was shot down over the shipyards by Republic anti-aircraft emplacements, but it crashed near the Shipwright Auxiliary Spaceport with several active warheads still attached.

Fortunately for the civilians and military in the area, Sergeant Larus's explosives experts managed to disarm the ordnance before they ignited the gas conduits underground and ripped apart half of Coronet City. With the Republic's help, CorSec established a command center in the Gilded Descent Casino, and the casino's owner Hannak Vrish turned to betting on the conflict as a new source of revenue. However, he was still willing to aid the Republic war effort out of both loyalty and desire for profit, so he helped the Republic rewire several of his hidden cameras in the region to spy on Imperial movements. When the Empire seized the Rendili Vehicle Corporation's facility in the Blastfield Shipyards, the company's personnel managed to evacuate but left behind several newly developed shuttles. A recovery attempt led by Sergeant Herron failed to retrieve the shuttles when a large group of mercenaries hired by the Empire was discovered guarding them, and Herron was forced to seek aid from other Republic and Jedi forces. A strike team was able to infiltrate the warehouse and open an access tunnel for Herron's men, and the sergeant and his subordinate Yung led the unit in stealing the shuttles while the strike team blew up a fuel depot outside as a diversion.

When Republic forces attempted to ship Councilor Haronn, one of the last pro-Republic Council members, off-world, his transport was shot down over Imperial territory in the eastern shipyards. Agent Halloway of the Republic Strategic Information Service enlisted the aid of both resistance members and Republic forces to successfully recover the Councilor before the Imperials could locate him in the Production Park region. The Blastfield Shipyards' gang-ridden Blue Sector became a battlefield when the criminal Coronas began to shake down resistance-friendly Corellians. When Ben Kahob was murdered by the Coronas for the medkits he was stockpiling for the Republic, Officer Danod of CorSec requested the Republic's aid in putting a stop to it. Answering Danod's request, a Republic and Jedi strike force attacked the Corona hideout, driving the gang out of the sector. One of Aves's subordinates, Lieutenant Bokete, discovered that the Empire was preparing to deploy special forces against the trapped Republic military, but died in the process of gaining the information. However, Aves's CorSec allies managed to gain information on the neutron emitters' location, and the general employed groups of Jedi and Republic operatives to take out the Empire's supply camps in the area so that he could reach the CorSec base in the Red Light Sector. There, the general and his allies learned that the emitters were located in the Imperial-held Coronet Shipping, but CorSec suspected that some of the Selonian tunnels ran underneath the Imperial base.

However, the CorSec officer who was meeting with the Selonians, Cole Cantarus, had been captured by the Empire and imprisoned in an Imperial-held CorSec station in the nearby Entertainment Plaza. Aves's forces assaulted the facility and rescued both Cantarus and his Selonian contact Gosse. With Gosse's information, the Republic began preparing for an assault on Coronet Shipping, but also freed her trapped den-mates from the Imperials at her request. The capture of Gosse's sept, or den-family, was part of the Empire's crackdown on the Selonians, whose efforts in aiding the resistance had greatly frustrated the Empire. The Imperials hired a bounty hunter named Vermilion, who had learned to fight Selonians during an earlier contract on one of their den mothers, and began to deploy specially-programmed war droids that targeted Selonians—regardless of whether they aided the resistance or not. However, the Selonian scout Lachei was able to locate the droids' command unit in the tunnels below the shipyards, and Republic forces were able to destroy the unit and thereby end the threat. As General Aves mobilized his forces in preparation for boarding the rocket trams, a Republic strike force attacked Coronet Shipping using the tunnels and inflicted heavy casualties on the surprised Imperials. After defeating the Imperial commander Captain Granta and his elite shock troopers, the strike force prepared to shut down the neutron emitters, but Aves informed his forces that the Imperials were already aboard the trams—they were going to attack the Republic forces in an attempt to stop them from moving out into the city. However, Cantarus protested that several dozen civilians were aboard the trams, and instead of using the emitters against the Imperials the strike team simply shut down the trams. Aves's men were forced to defeat the Imperials aboard the trams before they could board themselves, but the general later acknowledged that it was the right decision.

With the rocket trams accessible to the Republic once again, Aves's forces were able to further reinforce the resistance fighters in Labor Valley and renew their offensive in Axial Park. To the general's surprise, he and Captain Cantarus were contacted by Councilor Belos, one of the Council members who had helped the Empire in the invasion. Belos claimed to have had a change of heart, and was quick to explain to the general that his forces in Labor Valley were in danger—the Empire was utilizing prototype droids capable of bringing down any short-range vehicle, a technology developed under duress by Corellia's best scientists and technicians. Despite his suspicions about Belos's loyalty, Aves agreed to send some of his forces to aid the Councilor's assistant Deena Behar in stopping the droids. The Empire was producing the prototype droids in a secure facility with prison-grade vault doors, and since the doors would only open in an emergency, Behar directed Aves's forces to the captured Beharen Droid Factory, which specialized in disaster relief droids capable of triggering the doors. The assault on the factory was successful, with the disaster relief droids allowing the Republic forces to break down the doors on the Empire's lab. The chief scientist working on the prototype droids, Danison Varik, activated his droids in an attempt to kill the Republic forces, but he was taken into custody after his droids were defeated.

As the Republic's forces moved into Labor Valley and began to aid the beleaguered resistance members still in the area, the Corellian Chemical Corporation factory became a war zone when Republic forces tried to force the Imperials out of the structure. During the fighting, the factory took heavy damage, and a CorSec officer named Lanius Carr was forced to begin evacuation when it was discovered the factory was going to explode. Fortunately for the civilians in the area, Jedi and Republic forces were able to fight past the Imperial battle droids in the factory to shut down the chemical refining equipment, averting the disaster and hundreds of civilian casualties. Not long afterwards, the Drall doctor and environmental specialist Ernisto Misar discovered that the fighting in the factory had ruptured its main pipelines, causing toxic chemicals to spill into one of the city's aquifers. His clan was able to repair the pipelines thanks to the efforts of the Republic, whose agents recovered the specialized materials necessary for the repairs from the battlefield in the Labor Valley.

Doctor Tan Kirin, a Republic medical officer, sought help from the Jedi and Republic military in order to destroy smokescreen, a gaseous toxin that had been developed by Ardus Industries. Kirin was able to recruit a team of Jedi and troopers to liberate the company's factories and destroy the toxin, which was captured by the Empire when the factories had been seized. Amidst the continuing looting of resistance supply caches by Imperial forces, a Jedi by the name of Palla Mazlin attempted to defend one of the caches but was injured in the fighting. She was forced to seek help from other Jedi and Republic forces to retrieve the stolen medkits, shield emitters, barricades, and other equipment, and with the supplies the resistance was able to retain a foothold in the region as Republic aid continued to arrive.

Republic Captain Ranneth's patrol unit was ambushed by Imperial forces in the Advanced Product Research Sector of the Labor Valley, and he was the only member of his team to escape. A Republic rescue team was able to liberate the injured soldiers and deliver much-needed medical assistance before extracting them to the Republic's tram station. The Empire's continued bombing campaigns in the Labor Valley also damaged a munitions factory that was storing starship torpedoes, and Lieutenant Kallum's attempts to put out the fires and remove the detonite charges from the torpedoes failed when they were attacked by damaged and rampaging droids. Fortunately for the civilians and military forces in the area, reinforcements were able to fight through the droids to reach the torpedoes and disarm the charges, preventing the torpedoes from destroying the sector.

Pushing into Axial Park, the Republic was able to establish a safe house near the Leisure Garden, and General Aves's forces engaged the Imperial soldiers, Sith, and Imperial Guardsmen who had set up long-range artillery and defensive trenches across the Garden. Further offensives by the Republic resulted in the destruction of most of the Empire's walkers in Axial Park using their own heavy ordnance, the elimination of Imperial snipers in the Coronet Zoo, and the destruction of several long-range artillery pieces in the Leisure Garden. Aves's forces continued to press their advantage, attacking the Imperial Command Center in Archival Square and recovering vital information from the Empire's computer systems. An early action by General Aves's forces in Axial Park was to send a unit under Lieutenant Rufar to reclaim the Cross of Glory Walk, a memorial path in the Leisure Garden that honored the heroes of the Jedi Civil War, but the Empire's deployment of Mandalorian rocket-troopers allowed them to recapture the Walk and strike a blow to the Republic's morale. Imperial forces made a sport out of blasting Republic war memorials, and a group of CorSec officers were killed trying to protect the Carth Onasi monument. However, additional Republic and Jedi forces were able to drive the Mandalorians out of the area, reclaiming the holo statues and boosting morale. Sergeant Tanye Trila was among the officers who commanded troops in Axial Park during the fighting.

However, the Empire would not let the rocket trams out of their grasp without a fight. With the help of Imperial forces to fight off the Republic's snipers and troopers, the expert demolitionist Kapp Zyman detonated bombs along the rocket tram's green line and deprived the Republic of a vital route into Coronet.

But fortunately for the Republic, repair teams sent by Sia Norrin were able to repair a second line that had been damaged during an Imperial attack, giving the Republic an alternate route into Axial Park. An attempt to reprogram the Imperial artillery in the area failed when the astromech B3-RD was destroyed by Imperial snipers, but Republic forces recovered the targeting program from the broken droid and managed to install it in the Imperial artillery. As a result, the artillery began to target any Imperial bombers that approached nearby residential zones.

The Corellian Security Force Academy in Axial Park was captured by the Empire early during the invasion so that they could make use of SurvNet, a network of security cameras that covered Coronet City and fed back to the Academy. CorSec and the Republic made repeated efforts to reclaim the Academy throughout the battle, but it was not until Republic forces were recruited by Officer Silas to attack the Academy while he and his squad distracted the Imperials. The attack was a success, and additional forces rescued Silas, Hanley, Davit, Crissom, and the rest of his squad before they were overrun by the Empire. An Imperial unit under Commander Rigby captured the nearby Daoba Hotel and held the dozens of civilians inside hostage for several days while they installed heavy artillery atop the building. The Republic's Colonel Tott was unable to call in any airstrikes because of the civilians, but a combined Jedi and military effort freed the hostages so that an airstrike could remove the threat of the artillery.

Sergeant Gelens's Manka-class armored transport was attacked by Imperial forces and disabled, leaving his unit trapped inside the damaged walker in the middle of the battle-torn Axial Park. Republic forces were able to locate a distress beacon on one of his unit's body nearby, and Gelens managed to communicate his predicament so that the squad could be rescued. As the fighting continued, the data from the Imperial command center allowed the Republic to locate Commander Tainor, the head of the Imperial Guard, in the Imperial-occupied Museum Republica. A subsequent assault by an elite strike team resulted in Tainor's capture, and the Imperial forces in Axial Park were thrown into disarray with their commander in Republic hands, and Aves was able to push forward into the Government District itself.

Among the first reinforcements who would turn the battle in the Republic's favor was the group of Jedi under the command of the Jedi Knight known as the Hero of Tython. The Hero, who was attempting to foil the plans of the Sith Emperor and prevent him from completing a dark ritual that would allow the Emperor to consume the life of the entire galaxy, had learned that the corrupted Jedi Master Tol Braga was aiding the Sith forces on Corellia, and Grand Master Satele Shan immediately ordered the young Jedi to the planet. Suspecting that Braga would be able to block the Republic's efforts using his knowledge, the Grand Master began gathering reinforcements from the Outer Rim Territories and appointed the Hero as Supreme Commander of all Jedi forces on the planet. The Hero was the second to take that title; the previous Supreme Commander had been killed a short time earlier. With help from Captain Rikdine of the Republic Military, the Hero was able to gather the few remaining Jedi in the Blastfield Shipyards, battling through Mandalorians, war droids, and Imperial troopers while the Grand Master's reinforcements arrived. The Hero and the Jedi Unaw Aharo were able to fight off an attack on the apartment building of several resistance-friendly families, and the Knight then rescued fellow Jedi Bengel Morr from a group of Mandalorian mercenaries who had been pursuing the Nautolan across the shipyard's Entertainment Plaza. An attack on resistance forces in the tunnels beneath the western shipyards was also halted by the former Sith Lord Praven and the Hero, allowing the resistance fighters to push back the enemy in that area.

By the time the Jedi reinforcements arrived, General Aves's forces had successfully broken out of the Blastfield Shipyards, and the Hero's old ally General Var Suthra was able to establish a forward base in the Labor Valley before summoning the Knight to the region. In the Labor Valley, Suthra and the Hero strategized on how to locate Braga's forces in the area, and the Knight diverted the Outer Rim Jedi to recapture several weapons factories belonging to the wealthy businesswoman Magremme Thrakus. Thanks to the efforts of SIS Agent Helver, the Hero was able to locate a Sith strike force constructing a chemical bomb in the Saxan Chemical Refinery, and a subsequent attack on the refinery ended the Sith threat while the Outer Rim Jedi successfully retook Thrakus's weapons factories so that they could continue to supply the Republic war effort. Suthra was able to establish a base in the Corellian Science Museum near the Republic's main base in Axial Park, and his scientific advisor Doctor Nasan Godera identified Operation Firestorm, the Sith's next attempt to kill civilians: a set of advanced weapons known as Firestorm Turbolasers that had been adapted from the world-killing Desolator superweapon. While the Outer Rim Jedi freed prisoners from Imperial internment camps, the Hero of Tython destroyed the weapons in the Gowix Corp superstructure, Korvalus Tower, and Tyrelli Habitat around Axial Park's Archival Square.

But while the Jedi were gone, the Republic base in the museum was attacked by Imperial forces. Despite the death of Godera, his research enabled the Jedi forces to locate Tol Braga aboard the Imperial battle cruiser Eclipse above the Government District. Braga was attempting to detonate the Eclipses engines—an action that would destroy most of the district and spread radiation across most of Coronet—but the Hero was able to access the Eclipse via the secure turbolift that connected the cruiser to one of the government buildings. While General Suthra led the Jedi forces and his troopers in attacks on Imperial command centers across the region to distract the Imperials, the Hero boarded the cruiser and confronted Braga, defeating him and deactivating the engines before the Kel Dor was brought back to the light side of the Force.

However, in the midst of the battle, the Imperial Intelligence agent Cipher Nine pursued a third power that had been manipulating both the Republic and the Empire for ages: the secret society known as the Star Cabal. The Star Cabal sought to destroy both the Jedi and the Sith and thus end Force-users' control over the galaxy. The organization had managed to arrange for the dissolution of Intelligence's Operations Division after Cipher Nine and other agents had discovered the existence of the cabal, and the Cipher had been conscripted into the Imperial Military as a result. Cipher Nine was transferred into the unit under the Kaleesh Lord Razer, and the agent was ordered to contact Major Nedecca in the Incorporation Islands around the same time the Hero's Jedi forces were arriving on the planet.

Lord Razer was responsible for much of the bombing over the last six weeks, and twenty wings of B28 Extinction-class bombers were preparing to destroy Aegis Base—the Republic Army's main base in the region. Cipher Nine's assignment was to infiltrate the outer base and designate targets for the bombers as the first and second stages of the attack, and finally to plant a miniature baradium warhead in the heart of the structure. The agent's training and expertise proved essential in the assault, and the overall attack by Razer's bomber wings, led by Vynock and Kilit Squadrons, resulted in the total destruction of the Republic base.

During the attack, Cipher Nine was contacted by Keeper, the agent's former supervisor in Intelligence, and the two hacked into Republic communications to discover that Republic reinforcements were incoming. They also discovered that the Star Cabal was manipulating both militaries—hiding news of reinforcements and doctoring records so that both the Empire and the Republic would devote more forces than necessary and annihilate each other in the process. Keeper's assignment for the Cipher was to retrieve an undoctored record of the Empire's forces on the planet from Moff Alvon Zamar, who had been ordered to survey the occupation by the Dark Council. Therefore, the agent planted several landing beacons across Labor Valley in order to force Zamar's skyhopper to land, and Cipher Nine then rescued the Moff from the Republic Special Forces who were attacking his downed ship. With the report, Keeper was able to compare the two military forces and found that they were evenly matched, despite the recent use of Imperial troops by Thanaton, Kallig, Baras, and Vowrawn, but the Republic's reinforcements were about to tip the scale. This contradicted the Empire's belief that they had a numerical advantage, putting the Imperial offensive at a severe risk. The Cipher was then forced to travel to Lord Razer's new base in Axial Park when it came under attack by Jedi, but failed to arrive in time to prevent Razer's death.

During the attack, Keeper was able to determine that an airship above the city was being used by the Star Cabal, but it was defended by a group of mercenaries. To the Cipher's surprise, Keeper's plan to take down the Star Cabal required that Cipher Nine be "captured" and interrogated. To that end, the agent recovered access codes to a private shuttle and boarded the ship to carry out the plan, only to find that the Apocalypse Barge was a private ship owned by Corellia's wealthy so that they could watch their planet burn from above. Finding a hologram of Hunter, the Star Cabal member who had infiltrated the Strategic Information Service and manipulated Cipher Nine over the last year, the agent learned that Hunter had arranged the party to keep the party guests occupied and prevent them from aiding either side in the war. When Hunter's operatives captured the Imperial agent, Cipher Nine carried out Keeper's plan perfectly and convinced the Star Cabal that Imperial reinforcements were incoming—news that threw the cabal's carefully calculated plans into disarray. The Cipher Agent then escaped from Hunter's men to the Government District, where the intelligence operative followed Keeper's advice and staged a series of explosions in the Military History Museum to convince the Star Cabal that Cipher Nine was dead so that the agent could pursue the conspirators in earnest.

With the information gained from Master Braga, Grand Master Shan and General Suthra began to withdraw a significant part of the Republic's forces from Corellia in a risky gamble—an attack on the Imperial capital of Dromund Kaas itself, as a way of buying time for the Hero of Tython to confront the Sith Emperor in his Dark Temple. However, the Hero's Jedi forces remained on the planet to aid the military, and Supreme Commander Rans directed reinforcements to Corellia so that the Republic would not lose its advantage—the reinforcements that Cipher Nine had learned of during the assault on Aegis Base. The first of the two waves of reinforcements was a significant deployment of armor and infantry, led by General Elin Garza and the elite Special Forces unit Havoc Squad. The commander of Havoc Squad arrived not long after General Garza, and the general immediately ordered the major to prepare for their objective: taking out the recently arrived General Rakton, one of the Empire's greatest strategists and military leaders as well as a personal enemy of the commander. Rakton had taken command of the Bastion, which had remained in Imperial control ever since the black ops unit under Pierce had captured it early in the invasion, and the Republic would need a significant amount of troops to breach the compound.

With help from Officer Locke of CorSec and the pilot Captain Phaeris, Havoc Squad located a hangar in the Blastfield Shipyards that some of the squad's reinforcements could use to land, and also halted an Imperial firebombing campaign in a nearby civilian apartment district. The squad then rallied several resistance cells across the Labor Valley, led by Hendrick, Oudon, and Sherro, and led them in "blazing spear"—a coordinated attack on a nearby Imperial-held factory that would deprive Rakton of a contingent of his troops. The squad also secured an additional landing pad in the Corellian Museum of Starships by moving the historic assault shuttle Lucky Lancer, and with the support of Captain Lesher's Fifty-third Armored Platoon, Captain Marshall's Eighty-first Infantry, and the Special Forces Safecrackers under Lieutenant Coria, Havoc Squad began their assault on the Bastion.

Infiltrating the Bastion's main gate using a stolen Imperial crawler tank, Havoc Squad eliminated the outer defenses and opened the gate to allow the reinforcements in. The combined assault force then proceeded to attack the Bastion from three separate directions, overwhelming the prototype battle droids, Imperial walkers, infantry, and automated turrets defending the compound, and Havoc Squad proceeded deeper into the Bastion itself to locate Rakton while Lieutenant Coria and the others held the perimeter. Despite heavy resistance from the Imperial personnel within the fortress, the squad was able to fight through the defenders and capture Rakton himself, severely demoralizing the Imperial military. The Republic forces were then forced to evacuate the Bastion as Imperial fighters began to bomb the structure, but Rakton was successfully transferred into military custody and taken to Coruscant. Havoc Squad was summoned to meet with the Chancellor herself, though the rest of the assault force remained to aid the rest of the military on Corellia.

A second wave of reinforcements came from the Rift Alliance, a coalition of worlds considering secession that had recently returned to the Republic fold thanks to the Barsen'thor. Around the same time as Havoc Squad arrived on the planet, not long after the Hero of Tython's arrival, the Barsen'thor and crew landed on Corellia in search of their missing companion and attempted to triangulate the escape pod using emergency broadcasts. A broadcast from Captain Drizan in the private shipyard Zone Twelve caught the Consular's attention. Drawing from the Alliance's forces—Esh-kha warriors, Voss commandos, and Balmorran droids—the Barsen'thor dispatched aid to Drizan and Zone Twelve, and met with Drizan and the Selonian Quil. A recent Imperial bombing and the presence of Imperial XR-32 hunter droids prevented any attempts to track the pod, so the Jedi Master and a companion destroyed enough droids to break holes in the Empire's patrol routes in the shipyards. The Consular then reactivated two comm towers that the resistance had converted into anti-aircraft towers before locating the escape pod, and the Consular brought the missing companion back to the resistance's shelter so that the sentient holographic program Holiday could repair one of the files from the Javelin.

With the help of the Jedi Archives, Holiday was able to repair the file and reveal the identity of the First Son as Syo Bakarn. Horrified, the Consular contacted Bakarn and questioned the truth of the recording, but the First Son revealed that he would not relinquish control of the Jedi Master's body—and that the Guardian Holds were now under the Children's control. Tai Cordan, a Rift Alliance official, contacted the Consular not long after to report that the Guardian Holds had fallen. However, a few soldiers had escaped the Imperial capture of the nearby walker factory designated Guardian Hold Six, and the Consular rendezvoused with Alliance forces at the soldiers' camp in Labor Valley. After convincing their leader, the Jedi Jari Orez, that the Alliance forces were allies, the Barsen'thor learned from Orez that the soldier Aelan Kalder was the Child responsible for the Hold's capture. With aid from the Rift Alliance forces, the Barsen'thor led a counterattack on the Guardian Hold and defeated Kalder in battle before reactivating the factory.

The Rift Alliance's forces then moved onward into Axial Park, where Guardian Hold Four had been taken by the Children. The Barsen'thor and the Rift Alliance held a war council in the Republic's main base there, where they learned that the Guardian Hold—which used to be Bakvalen Hall, the home of Syo Bakarn's family, had a series of sensors across the park that would seal the manor's force field and blast doors. At the suggestion of the Voss Mystic Gaden-Ko, the Barsen'thor and the Rift Alliance again split their forces to take out each objective, and the Consular was able to break into the fortress. After defeating several members of the Imperial Guard, including their captain, the Jedi finally located the Child responsible for the Hold's fall—a corporal named Daresha—and defeated her in battle, after which the Consular captured the Hold's commanders, Generals Grann and Merion. Grann revealed that many of Corellia's top officials would be hiding in Guardian Hold One, a bunker in the Government District, but the First Son interrupted their meeting with a warning that the Consular's efforts would fail.

The Consular followed Grann's intelligence to the Government District and met with Sergeant Rossiker near Capitol Square, who was able to help the Barsen'thor triangulate the bunker's position using communication points around the Square. The Rift Alliance's forces captured several of the rooftop points while the Consular retook those guarded by Imperial Guards and Sith nearby, and with Rossiker's help the Jedi located the entrance to the Hold. Fighting through the Imperial defenders inside, the Consular found Secretary Nadien and Councilors Delquis and Saiak, two of the politicians who had joined the Empire willingly. However, Saiak soon revealed himself to be a Child of the Emperor, killing Delquis and forcing the Consular to defeat him in battle. A terrified Nadien urged the Jedi to use the tunnels in the Guardian Hold to follow the First Son into the caves beneath Coronet, and the Barsen'thor descended to confront what was left of Bakarn. In a final battle with the First Son, the Consular was able to redeem Bakarn and purge the First Son from the Jedi Master's mind, exposing all of the Children of the Emperor to the Jedi in the process. Not long afterward, the Hero of Tython's mission to confront the Emperor met with success as the Grand Master distracted the Imperial Navy in a battle above Dromund Kaas, and the Emperor was driven into a deep sleep to heal from his injuries.

Around the time that the Barsen'thor, Havoc Squad, and the Hero were on Corellia, a smuggler going by the callsign "Ace" became embroiled in the battle while pursuing a vendetta against the information broker Darmas Pollaran and Senator Bevera Dodonna, both of whom were actually traitors working for the Imperial admiral Harridax Kirill—the Voidwolf. The smuggler joined forces with Jedi Master Sumalee after rescuing a group of resistance fighters from a trap that Pollaran had led them into in the Blastfield Shipyards, and with Sumalee's help the smuggler tracked Pollaran to a factory owned by the corrupt Councilor Caicos. After capturing the traitor, the smuggler infiltrated the Corellian Museum of Alien History and capturing Dodonna before learning that the Voidwolf was gathering a massive pirate fleet to attack the Republic's main shipyards. To stop the Voidwolf, the smuggler broke into Caicos's mansion and used the Councilor's shuttle to access Kirill's flagship, the Regnant, and defeated the admiral in single combat before a holo-audience of the underworld's most powerful figures, thereby eliminating the threat to the Republic and turning the pirate fleet against the Empire.

Throughout all of these events, the fighting on Corellia continued, though the Republic gradually gained the upper hand. When the Republic discovered that the Empire had procured a Republic warhead from a classified source and were planning to detonate it underneath the Government District, "Operation Black Haze" was put into effect: an elite Republic squad was charged with locating and disarming the warhead with ion charges. However, the squad was ambushed before they could reach their object, and after learning of the operation from one of the fallen soldiers' datapad other Republic forces descended into the tunnels to complete the mission themselves. One particularly humiliating defeat for the Empire was the loss of the Coronet Ion Works, which had been converted into a major communications command post. Floor-by-floor, Republic forces under Colonel Rian Darok systemically eradicated the Imperial forces stationed there. During the fighting in Coronet, the Republic Medical Corps's Second Battalion did their best to evacuate civilians and deliver aid to those trapped on the battlefield, and a group of Corellian orphans who were saved by the unit nicknamed them the "Protectors"—a name that the noncombatant unit adopted. Colonel Marclonus of the Fourth Infantry was charged with securing the Republic's position in the western section of the Records and Communication Sector, but the Imperial Guard ambushed his troops and kidnapped several non-Human officers. Marclonus, who had spent ten years as a Hutt's slave messenger, was furious to learn that his men had been placed in shock collars, and enlisted the help of other Republic and Jedi forces when his commanding officer refused to send him any additional squads. At Marclonus's request, the reinforcements attacked the Imperial Guards and their shocktroopers, freeing the captive officers and driving the Empire out of that sector.

As the battle in the Government District heated up, the Empire began to deploy mortar cannons to blast the Republic forces out of the area. Sergeant Volos, his squads, and CorSec's Tactical Response Teams made progress against the Empire's forces near the main rocket tram station, but they were unable to proceed until Republic strike teams managed to eliminate the Imperial shock troopers guarding the mortar cannons and destroy the weapons. The supply frigate Fortress was vital to the Imperial supply chain on Corellia, and its loss would deal a severe blow to Imperial operations on the planet. Therefore, the Republic Military formulated plans for an assault on the craft, but the plans were stolen and brokered to Imperial Intelligence before the attack could take place. Fortunately for the Republic, operatives from both the military and the SIS managed to infiltrate the Imperial Intelligence headquarters in the occupied Corellian Communications Center. The recovery effort's secondary objective—to override the center's listening posts and relay Imperial data straight to the Republic—was also successful, allowing SIS operative Talash to intercept vital information on Imperial movements.

The Empire also began to deploy droids that took control of Corellian models, turning them against the resistance, but the plot was quickly discovered and stopped before it incurred many casualties. However, the Empire resorted to utilizing signal scramblers against Republic ships in the area, causing the Republic to target their own ships. After three medical transports were shot down over the Government District and killed their several hundred passengers, General Aves and the other commanders grounded all flights across the region. Fortunately for the Republic, Private Vekker of the Second Infantry recruited the help of other Republic operatives in taking out the Imperial forces guarding the control tower with the jammers, and after the scramblers were disabled Republic air traffic could resume. The Empire soon began deploying starfighters on bombing runs across the Government District against Republic troops, but Captain Bathens refused to authorize a military strike against the starfighters' hangar out of the belief that the structure was too well defended. However, the mercenary Trigo Shane, who had been hired by the Republic as a consultant, managed to convince several Jedi and Republic operatives to launch a concentrated assault on the hangar, and the strike team successfully ended the Imperial threat when they blew up the building with demolition charges.

In the Government District, Captain Cantarus was informed by Councilor Belos that the Empire had a surprise in store for the Republic: the Ion Wall. The destructive weapon would deactivate all electronics in its target area, rendering the Republic's forces helpless, but Belos alerted Cantarus to the location of the Ion Wall's emitters. With that information, the Republic was able to realign the emitters and target the Legislature instead, and a strike team infiltrated the Intra-Corellian Intelligence building to reach the Ion Wall's controls. In the process, the strike team encountered and defeated Darth Acharon, a member of the Dark Council who had been sent to Corellia after Tormen's success with the Chancellor cast doubts on Decimus's ability to lead the battle. The successful activation of the Ion Wall stripped away a significant amount of the Imperial defenses around the Legislature, allowing General Aves's forces to enter the Legislature itself.

With reinforcements from CorSec and the Green Jedi, Republic forces were able to fight through the heavy Imperial presence in the Legislature and reach the building's holdout room, where a strike force defeated the Dark Councilor Darth Hadra and arrested the members of the Corellian Council who were still aiding the Empire. The Sith Lord Savik was defeated by Republic forces and left for dead, though she was rescued by her droid servants and clung to life. A final push into the Speaker's Courtyard saw the death of Darth Decimus himself—an event that was broadcast across the entire planet, throwing the Empire's forces into disarray. General Aves, Cantarus, and Belos capitalized on their success by contacting Supreme Chancellor Saresh from the Legislature's Press Room, and Saresh delivered a resounding victory speech before the Galactic Senate.

With the death of Darth Decimus and the public declaration of a Republic victory, Imperial forces were thrown into confusion across Corellia. The Dark Councilor Darth Marr, recognizing that the loss of the Emperor, the turmoil in Hutt Space, and the ongoing attempt to capture Denova had left the Empire vulnerable and unable to sustain the Core offensive, appointed General Adele Konya as acting commander and ordered her to withdraw all Imperial forces, redirecting them with General Hesker to Ilum. During the fighting on Corellia, the SIS discovered that the Empire had been mining Adegan crystals from the Jedi's holy world for quite some time in order to develop a stealth armada, and the Republic immediately gathered its allies in order to stop the Empire on Ilum. However, Konya was also given the assignment of staying behind with a task force on a suicide mission—to take control of the Black Hole hypermatter refinery. The victory on Corellia greatly helped Republic morale, as it turned back the Imperial Core offensive and gave the Republic hope of winning the war. The loss of five Dark Councilors, three of whom fell at Corellia, weakened the Empire's power structure, and the fighting had cost the Empire a tenth of its military upon Corellia. During the mop-up actions led by General Suthra and the newly promoted Jedi Master Unaw Aharo, Aharo came across a group of Imperial and Republic officers who were planning to sabotage their own forces by ramming their vessels into their respective fleets' flagships; he was unable to prevent the traitors from doing so, and their actions deeply troubled the Jedi. The culprits had secretly been members of the fanatical Order of Revan, which had members among both the Republic and the Empire.

The Battle of Corellia appears throughout the video game Star Wars: The Old Republic, released by BioWare and LucasArts. The events of the invasion are detailed throughout the in-game Codex, while the events of the occupation and the battle are described through the Imperial and then Republic world and class missions. All missions can be completed by a group of players, and any class can complete both the world missions and side missions. Therefore, this article refers to the player characters in each quest as a group of Imperial or Republic operatives, and assumes that each faction completes their respective missions according to their respective alignments. The ultimate outcome of the battle is confirmed to be a Republic victory by both Imperial and Republic NPCs in the mission series for the Black Hole PvP area, and the short story The Last Battle of Colonel Jace Malcom also states that the loss at Corellia forced the Empire to abandon its Core offensive.

The events of the Imperial Agent storyline on Corellia tie into several of the other class storylines, placing the Sith Warrior and Inquisitor storylines before the Agent and the Jedi Knight, and the Trooper and then the Jedi Consular after the Agent's. The Bounty Hunter storyline takes place earlier than any of the other classes, as the Republic is largely not present on the planet in the class missions until Darth Tormen's broadcast. Chancellor Janarus is removed from office during the conflict, with Governor Saresh replacing him and receiving General Aves's victory speech at the end of the battle. Comments made throughout the various missions also confirm that the battle lasted a significant amount of time, with Lord Razer's forces having conducted a bombing campaign for the last six weeks at the time of the Agent storyline. The Jedi Knight storyline takes place before the Trooper and Consular classes, as there are few Jedi on the planet at the time, though the Consular storyline must end before the Knight defeats the Emperor. This is because a companion mission for Kira Carsen, a companion character for the Knight class and a former Child herself, reveals that the Children of the Emperor are barely able to continue without the guidance of the Emperor and the addition of his incoherent raging while he sleeps. The Smuggler class, however, has no information on where it occurs in relation to the rest of the classes, so this article only assumes that it occurred sometime during the other classes' storylines.

While the Battle of Corellia was first hinted at in Corellia's entry in the HoloNet section of The Old Republics official site, it did not appear until the release of The Art and Making of Star Wars: The Old Republic in November 2011. The game itself was released December 20, 2011, and the battle was a major part of the story on Corellia, which is a level 48-50 planet. Characters, missions, and locations in the battle appeared in the Star Wars: The Old Republic Explorer's Guide, which was released concurrently with the game, and the short story "The Last Battle of Colonel Jace Malcom" revealed the canonical outcome of the battle upon its release in Star Wars Insider 137 in October 2012. The novel The Old Republic: Annihilation, released in November 2012, further confirmed some of the events of the battle, including Darth Hadra's death.

In the Jedi Knight mission "Firestorm," the three buildings can be visited in any order during the mission, so this article refrains from specifying the order, though Doctor Godera's comments to the player at the beginning of the mission erroneously indicate that there are only two buildings in which the Sith are working. According to the game's conversation files, the mission "Firestorm" originally had the player accompanied by Unaw Aharo, and the shuttle would be damaged by Republic artillery on the way to the first turbolaser. Aharo would repair the shuttle while the player took out the second turbolaser, though players could leave T7-O1 to repair the shuttle and take Aharo. However, this version of the mission was ultimately cut from the game. The Jedi Consular, Jedi Knight, and Trooper classes all see players commanding military forces, and most of their class missions on Corellia feature alignment choices as to how to commit those forces. As these three classes are Republic classes and are thus considered to follow the light side alignment choices, this article details those outcomes above. The dark side alignment choices, where one's forces are committed to goals such as attacking Imperial medical camps or working for bribes rather than aiding the resistance, result in the loss of the forces under the player's command. Some class missions deal with other choices, such as the Trooper class's decision whether to destroy the Lucky Lancer or to allow the resistance to fly it away. The Bounty Hunter class can choose to not kill Janarus and instead kill Darth Tormen, after which Janarus will resign due to corruption charges.
