Battle of Thyferra The Battle of Thyferra marked the end of the Bacta War between Rogue Squadron and the Thyferran government , which was backed by Ysanne Isard . Having collectively resigned their commissions in the New Republic Defense Force , Rogue Squadron waged a campaign for several months to undermine Isard ’ s rule , remove her monopoly on bacta , and free the prisoners held on Isard ' s flagship , the " Lusankya " . The campaign ended with the Battle , which achieved all of the objectives except the last , and Isard , unknown to Rogue Squadron , escaped . Prelude . Although Rogue Squadron ’ s hit - and - fade tactics had been highly effective against Isard ’ s bacta convoys and processing stations , Wedge Antilles and Tycho Celchu knew that sooner or later they would have to directly confront Isard ’ s superior forces . To that end , their objectives were to augment their own forces as much as possible , while reducing Isard ’ s . Both objectives were furthered during the Second ambush in the Graveyard , when the sudden appearance of the Thranta - " class " War Cruiser " Valiant " allowed Rogue Squadron to destroy the " Victory II " - class Star Destroyer " Corrupter " ( thus killing Isard ’ s most aggressive commander , Ait Convarion ) , and add the " Valiant " to its forces . Prior to the battle itself , Antilles recruited a large fleet of smuggler freighters to participate in the final campaign , and bribed Captain Sair Yonka to desert Isard and bring his ship , the " Imperial II " - class Star Destroyer " Avarice " with him . The Battle . Phase One : Yag ' Dhul . Having exposed Talon Karrde ’ s employee , Melina Carniss , as a spy for Isard , Rogue Squadron allowed her to inform Isard of the location of Rogue Squadron ’ s base of operations at Yag ' Dhul . Isard immediately dispatched the " Lusankya " and the " Virulence " to destroy the space station . Just as the " Lusankya " arrived , Rogue Squadron entered hyperspace at the edge of the system , bound for Thyferra . " Lusankya " ' s commander , Captain Joak Drysso , deployed his fighters and prepared to destroy the station . Booster Terrik , in command of the station , trapped the " Lusankya " using a gravity well projector and the station ’ s heavy - lift tractor beams . He then locked over three hundred proton torpedo targeting systems onto the ship . In reality , the actual launch systems had been mounted on the freighters , but the bluff was enough to give Drysso pause . At that moment , the " Virulence " wedged itself between the " Lusankya " and the station , breaking the target locks . Drysso ordered the ship to immediately retreat back to Thyferra , leaving its fighters behind . Unplanned by either Booster or Wedge , Pash Cracken ’ s Ace Squadron then arrived , completing the illusion that the New Republic had set a trap . The " Virulence " ’ s captain , Lakwii Varrscha , immediately surrendered . In one stroke , the Rogue forces had deprived the " Lusankya " of its fighter complement , and Isard of her last remaining " Imperial II " - class Star Destroyer . Phase Two : Thyferra ( Space ) . Rogue Squadron rendezvoused with its allied freighters , which then jumped to Thyferra . The squadron ’ s X - wings had just begun to engage the interceptors of the Thyferran Home Defense Corps , led by Erisi Dlarit , when the " Lusankya " arrived back . The battle was complicated by the arrival of the " Valiant " and the " Avarice " ( re - named the " Freedom " ) . The two capital ships engaged the " Lusankya " , while the Rogues unleashed massive salvos of proton torpedoes and concussion missiles , using the freighters as launch platforms slaved to the starfighters ’ telemetry . The " Lusankya " ’ s bow shields were overwhelmed . The " Lusankya " shifted its fire to the freighters , hoping to take them out of the fight . Phase Three : Thyferra ( Ground Assault ) . At the same moment as the Rogue forces arrived , Elscol Loro and Iella Wessiri led a force of Ashern and Zaltin rebels in an assault on Isard ’ s palace . When they managed to penetrate the defenses , Isard escaped in Fliry Vorru ’ s personal shuttle " Thyfonian " ( or so it appeared ) . Vorru was left behind and captured , to be returned to Kessel . Phase Four : Thyferra ( Space ) . It was at this time that Isard commanded the " Lusankya " to cover the escape of the " Thyfonian " , before both were lost in the battle . By this time , Rogue Squadron and the freighters had run out of missiles , and the " Freedom " was badly damaged . Captain Drysso disobeyed Isard ' s order to flee , believing he would win the battle and take her place on Thyferra . When the " Virulence " reappeared , he thought that he finally had the reinforcements he needed to win the battle . However , the " Virulence " was now under the command of Booster , and it contained three New Republic A - wing interceptor squadrons , including Ace Squadron . The assault on the " Lusankya " was redoubled , and fighters began taking out whole sections of the ship with their strafing runs . Drysso threatened to ram the ship into Thyferra , but he was executed by Lieutenant Waroen , who then surrendered the ship and her crew to Rogue Squadron . Outbound from Thyferra , Isard also ordered Erisi ’ s TIE squadron to cover her exit . Corran Horn engaged Erisi one - on - one , and shot her down over one of Thyferra ’ s moons . He then engaged Isard ’ s shuttle , and , with Tycho ’ s help , managed to destroy it before it entered hyperspace . This ended the battle . Aftermath . Rogue Squadron was disappointed to find that the prisoners on board " Lusankya " , including General Jan Dodonna , had been evacuated to another location before the battle . It would be several years before they were finally found and liberated . In recognition of his contribution to Isard ’ s downfall , Ooryl Qrygg was made " janwuine " , an honor in Gand culture which allowed him to refer to himself in the first person . Rogue Squadron was invited to rejoin the New Republic military . Through negotiations mediated by Talon Karrde , the New Republic reluctantly allowed Booster to keep ownership of the " Virulence " . The ship was renamed the " Errant Venture " . As temporary captain of the " Lusankya " , Wedge performed an impromptu marriage of Corran Horn and Mirax Terrik . Xucphra Corporation was disbanded , and Zaltin Corporation became the dominant Human faction on Thyferra . Isard was believed dead . It was not until after the Thrawn campaign that she re - appeared , revealing that she had not been on the shuttle , which was remotely controlled , and had survived the battle .
