Spreading the Rebellion Spreading the Rebellion was a Rebel Alliance military campaign designed to win the support of the Airam sector that turned into a quest to destroy Imperial Task Force Vengeance . The Imperial force had been sent to pacify the sector , as well as to destroy the Rebel shipyard established in the Nocto system . The campaign occurred at roughly the same time as the Sepan campaign . Origins . The campaign was planned in order to counteract the formation of Task Force Vengeance by the Galactic Empire , which was deployed in neighboring Elrood sector . The Alliance , being no match for a task force of this size , ultimately decided to give up their permanent assets in Elrood in favor of the more remote and less strictly controlled Airam sector . Withdrawal from Elrood . In the opening days of the campaign , many assets in Elrood sector were evacuated , most notably XQ5 Platform - turned - hospital " Hormuuz " in the Gelgelar system . Most places were able to avoid Imperial attention , but " Hormuuz " attracted the attention of Admiral Senn , who deployed a strike team to capture any Rebels in the system . Even when the wounded escaped with the help of Rogue and Gold Squadrons , they were not safe , as Senn ruthlessly pursued the escaping transports and the assisting medical frigate " Redemption " . Eventually , the Rebel Forces managed to regroup in the border regions of Airam sector . Rebel High Command decided this area to be of increased strategic importance and directed more equipment towards the sector fleet around Calamari Cruiser " Liberty " . The first convoy would be a shipment of B - wing starfighters , increasing the overall strike capability of the Rebel Fleet in Airam sector , with material for construction and maintenance of a capital - class shipyard following in the subsequent weeks . At some point the Alliance tried to regain the initiative over Task Force Vengeance and struck at their former base at Gelgelar to retrieve vital supplies left behind during the evacuation . The gravity well technology . Stocked up on consumables and warheads , the Alliance went on to find out their enemies strength — many reconnaissance missions were flown by Rogue Squadron in order to scan the ships of Task Force Vengeance and destroy any freighter carrying warhead supplies . This culminated in a diversionary strike by the Cruiser " Liberty " herself , intended to lure away some of the Imperial warships into an ambush set in the Goff system . The ambush nearly became a trap when the Imperial warships were accompanied by the Interdictor Cruiser " Compellor " , pinning the Alliance ships in realspace . Once the Interdictor had been driven off , however , the Alliance ambush prevailed , and Rebel High command had a new goal in their sights : getting their hands on the gravity well technology . Rogue Squadron led a strike team to capture the Interdictor while it was undergoing repairs . The attempt was successful , and despite the Empire ' s attempts to scuttle the " Compellor " , the Rogues were able to bring the ship safely to the Mobetta system . By maintaining tight patrols around the factory , " Gallofree " , the Rebels managed to keep the modifications performed on the Strike Cruiser " Peregrine " a secret , prepping the " Compellor " for its final mission as well . The baptism of fire for the " Peregrine " came shortly thereafter in the Derilyn system , where it assisted " Liberty " in pinning down and destroying a reinforcement and resupply fleet headed for Task Force Vengeance . Meanwhile , an Imperial strike force " found " the " Compellor " - which blew up in full view of the Star Destroyers " Titan " and " Juggernaut " , according to Rebel plan , leading the Imperials to believe that neither they nor the Alliance had access to gravity well technology anymore . The end of Task Force Vengeance . The destruction of the " Compellor " caused the two Star Destroyers to attack the factory which had assisted in the modification of the " Peregrine " , and Alliance forces responded to the distress call , helping in the evacuation process . Being grateful for the quick rescue of his people , clan leader Tamaron of the Airam sector agreed to supply the Alliance with much - needed warheads . The transfer was accomplished with relatively little interruption in the Kuras Drift . In the closing days of the campaign , Task Force Vengeance was already showing the effects of raids against their supply lines . In a last ditch effort , Senn tried to acquire supplies from the traitorous Airam clan leader Ilay , but was foiled by the efforts of Rogue and Green Squadrons . The Alliance , intent on wearing down the remainders of the Imperial Task Force slowly but steadily , did not expect Admiral Senn to know the location of their most crucial asset in the Airam sector by this time : The shipyard " Calenz " . The Super Star Destroyer " Vengeance " , accompanied by the Star Destroyer " Rage " , launched a direct attack against the facility ( Battle of Nocto ) . The ultimate outcome is unclear , although it is believed that both the shipyard and the Super Star Destroyer were destroyed in the climactic battle .
