Battle of Rocrin The Battle of Rocrin was a bloody conflict that occurred during the operations of Task Force Vengeance in the Airam sector . Prelude . The Empire had acquired reliable information that a large Rebel convoy would be transiting through the Rocrin system . In response to this , the " Imperial " - class Star Destroyer " Rage " and interdictor " Compellor " readied an ambush there . Unlike previous engagements , there was a modification to their standard search - and - destroy orders . Admiral Wooyou Senn , desirous of learning what cargoes were being carried so as to better cripple the Rebellion ' s forces , issued the command that all ships be scanned before destruction . To carry out such a task , the Empire ' s pilots were reminded , speed was life . The Battle . Star Destroyer " Rage " and interdictor " Compellor " arrived undetected at the chosen interception point . Once again , starfighter support was provided by Avenger Squadron in its shielded TIE / IN interceptors , Beta Squadron in its TIE / sa bombers , and Gamma Squadron in its TIE / LN starfighter s . To better facilitate Gamma Squadron ' s protection role , its fighters were modified to carry and fire concussion missiles . Soon the Rebel convoy arrived , unceremoniously torn from hyperspace by " Compellor " ' s gravity well projectors . Recognizing their immediate foes in the bombers of Beta Squadron , the Rebel A - wing escort , Oro Squadron , turned on them with missiles and lasers . " Rage " ordered Gamma to intercept while Avenger Squadron closed in on the freighters and corvettes . The dividing kilometers were crossed and the fight began . Avenger Squadron , dodging missiles and laserfire from the lead ship , " Assassin " - class corvette " Croisade " , established that it held technicians of some kind . In quick succession , the other ships were inspected . Modular conveyor " Rakan 1 " held a fabricator ; " Rakan 2 " , to the Imperials ' astonishment , had a large reactor aboard . Other goods fit for the construction of a base were also found . Beta moved in on the convoy . However , the Rebels had placed a distress call and no sooner had the first cargo ship was destroyed did X - wings from Ulan Squadron began to arrive . Knowing that the Empire trapped them through interdictor " Compellor " alone , the X - wings had been equipped with proton torpedos and were given the cruiser as their target . Avenger Squadron , its inspections complete , joined Gamma in facing this new threat . Meanwhile , the convoy continued to suffer torpedo hits . Its troubles worsened when " Rage " came into range and added its own bombardment . With its Oro Squadron escort being destroyed around it , the Rebel starships were eradicated . Ulan Squadron failed to drive off the " Compellor " , and the Imperial starfighters hunted down the X - wings one by one and destroyed the Rebels to the man . Aftermath . Although Task Force Vengeance had scored another victory , its commanders , including Admiral Senn , were not without concern . Even as Imperial success mounted , so did the evidence of the Rebellion ' s substantial buildup in the sector . Furthermore , despite the convoy ' s loss , the Rebellion stepped up its efforts and matched the Empire ' s pressure . Not only did it construct " Soren " , a starship component factory , in the Mobetta system , but it also assembled " Calenz " , a shipyard capable of producing medium - sized warships , in the Nocto system . It was clear to both sides that the campaign was far from over .
