Battle of Bastion The Battle of Bastion was fought between the forces of the Imperial Remnant Grand Admiral Gilad Pellaeon and those of the Yuuzhan Vong Commander B ' shith Vorrik . It resulted in the loss of the Imperial capital Bastion . The Battle . While aware that a Yuuzhan Vong force was approaching their space , Imperial spies reported that the attack was aimed at the Hand of Thrawn at Nirauan . When Vorrik ' s forces instead arrived in the Bastion system , the Imperial Navy was caught completely off guard as the Yuuzhan Vong destroyed planetary defenses with ease . Despite this , the Starfleet was able to hold its own at first , until the Yuuzhan Vong pulled back . What the Remnant expected to be a retreat was soon revealed to be the launch of a swarm of thousands of grutchin s . The fleet responded to the grutchins with appalling disorganization ; only Pellaeon ' s own Star Destroyer , the " Chimaera " , responded with appropriate efficiency and effectiveness on short notice . The resulting losses forced Pellaeon to order the evacuation of Bastion . As separated elements of the fleet fought and attempted to regroup , a small Jedi expedition that included Luke and Mara Jade Skywalker , arrived aboard the " Jade Shadow " . After assessing the situation , they jumped toward the gas giant where a force composed of the " Chimaera " , the Imperial Star Destroyer " Superior " , and their support craft were pinned against planet ' s gravity mass shadow by a powerful enemy contingent . The Jedi provided Pellaeon with information on the location of the enemy ' s yammosk before departing for Yaga Minor . Pellaeon dispatched TIE Fighters to deal with the yammosk carrier and then attempted to break out of the gas giant ' s mass shadow . The " Superior " was critically damaged and Pellaeon ordered its evacuation as it fell into the depths of the planet . The " Chimaera " had also taken considerable damage by the time a coralskipper rammed its bridge . The suicide run nearly killed Pellaeon , but a junior officer pulled the Grand Admiral from the bridge and loaded him aboard a medical frigate carrying survivors from " Superior " . Under the cover of wreckage from the dying Star Destroyer , and the brave sacrifices made by a dozen of the " Superior ' s " TIE Fighter pilots , the frigate was able to escape for Yaga Minor . Toward the end of the battle , a Yuuzhan Vong slaveship arrived over Bastion and began to harvest Imperial citizens who had been unable to escape in time . Aftermath . While caught off guard , the efforts of the Imperial Navy enabled most of Bastion ' s population to escape in time . Upon arrival in the Yaga system , the shuttle ' s pilot , a Human male named Vitor Reige , ferried Pellaeon to the Imperial frigate " Widowmaker " . The Grand Admiral ' s life was saved due thanks to surgery from the Chadra - Fan Jedi healer Tekli . Pellaeon ' s survival restored the Imperial chain of command . Despite the evacuation of their commander , the crew of the " Chimaera " successfully managed to retreat from Bastion and afterward limped into Yaga Minor . Now provoked , the Imperial Remnant chose to ally with the Galactic Alliance against the Yuuzhan Vong empire .
