Battle of Corellia ( Second Galactic Civil War ) The Battle of Corellia took place in 40 ABY during the Second Galactic Civil War . It resulted in the withdrawal of Galactic Alliance forces from the Blockade of Corellia and the formation of the Corellian Confederation , which was soon renamed the Confederation at the insistence of Bothawui and Commenor . Prelude . The Blockade of Corellia was taking its toll on the system and supplies were very low . But the recent assassinations of Bothans on Coruscant turned Bothawui into a potential ally of the Five Worlds . The Galactic Alliance frigate " Shamunaar " coordinated all reconnaissance in the Both system to ensure that they wouldn ' t come to Corellia ' s aid . But the Sith Lady Lumiya manipulated former Galactic Alliance Admiral Matric Klauskin into taking control of the " Shamunaar " and killing the crew by opening the ship to vacuum . He then turned over the frigate to Tathak K ' roylan , who would lead Bothan forces to help break the blockade . The battle . Surprise attack . When the Bothan and Commenorian fleets arrived at the Corellian Exclusion Zone , Corellian forces throughout the system immediately launched from the surface and attacked the Galactic Alliance Second Fleet in an all - out effort to break the blockade . Aboard the " Dodonna " Admiral Limpan immediately recognized the poor odds of defeating the combined enemy fleets and ordered the majority of Galactic Alliance forces to attack Centerpoint Station . Soon the " Dodonna " , " Blue Diver " , and the " Anakin Solo " were en route to deal as much damage as possible before retreating . Escorting the " Errant Venture " . As the battle continued Wedge Antilles and Corran Horn launched from the " Errant Venture " to protect it from attacking Corellian forces before it entered Hyperspace . They were soon joined by Luke and Mara Jade Skywalker in their StealthX s and formed Ganner Squadron which was named after Ganner Rhysode . The " Dodonna " ordered the " Errant Venture " to launch all spaceworthy fighters before leaving , which meant more time that the under armed Star Destroyer was vulnerable . They managed to fight off a EF76 Nebulon - B escort frigate and six I - 7 Howlrunner s before the " Errant Venture " safely entered hyperspace . Attack on Centerpoint Station . At this point there was no hope to defeat the rebel forces so the best option was for the Galactic Alliance task force to focus the majority of their firepower on Centerpoint Station . The " Blue Diver " engaged two " Carrack " - class gunships while the " Dodonna " and " Anakin Solo " assaulted the station . The Bothans used this to their advantage by inflicting a devastating amount of damage to the " Dodonna " while all it ' s turbolasers were occupied . The Alliance forces managed to leave two large gashes in Centerpoint Station before retreating . Aftermath . Overall the battle was a disaster for the Galactic Alliance . Now there was no chance for a negotiated peace with the Corellians . Along with Commenor and Bothawui , Fondor , Bespin and Adumar also joined the newly formed Confederation . The loss of planets with major shipyards such as Corellia and Fondor were a critical loss to Alliance ship production . The " Galactic " - class battle carrier " Dodonna " was heavily damaged during the battle and spent the rest of the war out of commission being repaired . The Galactic Alliance and Confederation spent the next few weeks of the war launching a series of minor attacks on each other ' s shipyards such as the Raid on the Gyndine Shipyards .
