Battle of the Bajic Shipyards The Battle of the Bajic Shipyards was a battle that took place at the Vergesso Asteroids some time after the Battle of Hoth , in which a major Rebel / Smuggler base was destroyed by the Empire . Prelude . Ororo Transportation , a front company for the Tenloss Syndicate , had long operated the shipyard in Vergesso Asteroids . The Rebel Alliance had established a key base there some time after the Battle of Yavin . The Galactic Civil War had resulted in strange bedfellows , as some Rebel personnel had questioned working with a corporation that had ties to organized crime . However , the arrangement was mutually beneficial to both the Rebels and Tenloss , as the resource - strapped Alliance was fortunate to have such a facility at their disposal , while the presence of Rebel forces augmented the defenses of the syndicate ' s shipyard and discouraged reprisals from rival criminal organizations . Nebulon - B frigates regularly lurked among the asteroids . They often shut down all but the most essential systems , drifting among the planetoids so they could save consumables and attract even less attention , though it often took 45 minutes to get into a combat - ready stage . Aeron and Ace Azzameen learned from friend and Rebel pilot Olin Garn that the Alliance base in the Vergesso Asteroids was critically short on supplies . The siblings teamed up to raid supplies from the Viraxo , a rival shipping family . During the raid , Black Sun Supa Fighter s came to the assistance of the Viraxo " Razor " - class Starfighters . The Azzameen craft managed to escape to the Vergesso Asteroids , but were tracked by a couple of Supa Fighters . Though the fighters were destroyed , the Rebel outpost was compromised to the Black Sun organization . In an attempt to gain favor with Emperor Palpatine ( and embarrass Darth Vader at the same time ) , Prince Xizor provided the location of the outpost in the Bajic sector , saying that a large number of Rebel vessels were currently undergoing repair at the facility . The Emperor tasked Vader with the responsibility of personally overseeing the shipyard ' s destruction , against Vader ' s own preference as he did not consider it necessary that he go along for the assault , believing any half - competent line officer could see it through to successful completion . He selected Admiral Okins to join him in command of the Executor for the expedition . This act served a double purpose for Xizor . Not only did it allow him to gain more favor in the eyes of Palpatine , but it would serve as a fitting punishment for the Tenloss Syndicate who had recently incurred the wrath of Black Sun . The battle . Nearly a standard week after Xizor disclosed the location of the shipyard , the Imperials exited hyperspace at the base . Vader brought his flagship , " Executor " , " Imperial II " - class Star Destroyer " Avenger " and two " Victory II " - class Star Destroyers for battle . The Rebel shipyard was a giant asteroid housing hundreds of docked starships undergoing repair , less than a challenging operation . Before Okins could bring his task force to engage the shipyard , however , several Rebel capital ships emerged from behind the asteroid , and suddenly Okins was faced with a considerably greater opposition . The Rebels immediately deployed over a dozen starfighters to meet the Imperial task force , to the annoyance of Okins . He ordered the " Executor " TIE operations officer to scramble their own fighters in response , not caring to waste the " Executor " firepower on such insignificant targets . Still , the presence of Rebel fighters proved enticing to Vader , who chose to join the battle in his own custom TIE fighter , despite Okins ' voiced reservations , leaving the destruction of the shipyard solely in Okins ' hands . Aeron Azzameen , who recently arrived at the base , put out a distress call to her younger sibling Ace , who departed from the nearby Mon Calamari Star Cruiser " Liberty " aboard " Otana " . Meanwhile , the attack continued on the base uninterrupted . Vader himself entered the battle in his personal fighter and easily destroyed seven enemy fighters . However , sensing none of the excitement he had experienced in his fight against Luke Skywalker at Bespin , he withdrew from the battle in disgust . In the meantime , with the defending Rebel fighters being overwhelmed by TIEs , the Star Destroyers easily dealt with the Rebel frigates . The Imperial Fleet then commenced its attack on the shipyard itself . As the battle neared its conclusion , " Otana " arrived , dodged the swarms of TIE / LN starfighter s and other craft in the area , and docked with Vergesso Prime , Ace intent on rescuing his sister . Aeron eventually boarded " Otana " , which disembarked from the station shortly before its destruction and joined the other survivors in fleeing the area . As soon the assault concluded , the " Executor " immediately returned to Coruscant so that Vader could return to his domestic affairs . Although 65 % of the station ' s personnel had escaped , very few Rebel fighters and warships survived , so this was a serious loss for the Alliance . It also dealt a heavy blow to the Tenloss Syndicate and taught them a lesson : never to cross Black Sun again . Behind the scenes . In a glaring contradiction of both the description of the battle from the " Shadows of the Empire " novel and the level depicting the battle in the video game " " , the depicts the Rebels ' asteroid base as a verdant , inhabited planet , rather than an asteroid , which the " Executor " fires upon .
