Attack on the Compellor During the Galactic Civil War , Imperial forces turned back a Rebel starfighter hit - and - fade against the interdictor " Compellor " . Background . In the wake of Task Force Vengeance ' s destruction of their construction convoy in the Rocrin system , the Rebel Alliance began to see just how dependent the Empire ' s campaign was on the Immobilizer 418 cruiser " Compellor " . Accordingly , the Rebels plotted a retaliation attack on it , timed for when both the " Compellor " and , unavoidably , its companion the " Imperial " - class Star Destroyer " Rage " were docked at the former Airam space platform Goff . The Empire too acknowledged the importance of " Compellor " , for at that stage should it suffer significant damage of any kind , further offensive moves would be forestalled for an indeterminate time — time unable to be lost . The Battle . The Rebels entered the Goff system with two squadrons of starfighters , Viper Squadron in its A - wings and Phoenix Squadron in its B - wings . The chosen attack profile was their standard hit - and - run tactic of missile - armed dogfighters out front and heavy assault fighters behind . Viper was to engage Imperial starfighters while Phoenix attacked the " Compellor " with a mix of proton torpedoes and mag pulse warheads . Against them were foes Avenger Squadron in its shielded TIE / IN interceptors , Beta Squadron in its TIE / sa bombers , and Gamma Squadron in its TIE / LN starfighter s . The Imperial starfighters were quick to move onto an intercept course , Avenger Squadron being ordered to redirect power to its engines so as to meet Viper Squadron before Phoenix Squadron came within range of Goff Platform . When the two sides met , Avenger and Viper Squadrons began a fight of missile locks and laserfire . Phoenix Squadron moved on but was , in turn , intercepted by Beta and Gamma Squadrons . A series of starfighter - to - starfighter battles ensued . Phoenix Squadron was able to launch some of its torpedoes at the " Compellor " . The Imperials were then ordered to shoot down the warheads . In the end , swarmed by multiple TIE craft , the B - wings were gradually shot down , as were the A - wings . At this point , the second flight groups of both Rebel squadrons made their entry . They found not a bloodied defense force , but instead a robust Imperial armada amidst their comrades ' wreckage and debris . The Imperials , who had been gloating at the losses the Rebels were already suffering over their comm channels , switched their attention to warning their pilots that even more desperate attacks could be expected from their foes . The TIE pilots rose to the challenge , and the Rebel second wave went the way of the first . The " Compellor " was , for now , saved . Aftermath . Although the Rebellion ' s strike had been thwarted , the Empire was forced to admit that their enemies had caught on to them . The tactic of pairing an " Imperial " - class Star Destroyer with an interdictor cruiser was causing the Rebels great concern . Further attacks against the " Compellor " could be and were expected as Task Force Vengeance proceeded . As was typical in battles , a number of pilots survived the destruction of their craft and were rescued . Many of the Rebels so captured , despite their loyalties , were found to be quite eager to mitigate their situations by providing valuable information . What they reported unsettled the Imperials still further and set the stage for the next encounter at Mobetta .
