Destruction of the Separatist supply storage base During the Clone Wars , the Galactic Republic mounted a mission to capture a strategic Separatist supply storage base . The Republic and Jedi Order had received intelligence that the asteroid contained medications , weapons , ship repair materials , and foodstuffs which would be vital to worlds in desperate need . A joint Jedi and Republic force when to capture these supplies . However , the facility and all of its supplies were destroyed thanks to the efforts of Jedi Master Quinlan Vos , who was secretly serving as an agent of Count Dooku . Prelude . Towards the end of the Clone Wars , the Jedi Order received a tip about the location of a Separatist supply storage base . The base was massive and concealed within the interior of a asteroid . According to the source , the asteroid contained medications , weapons , ship repair parts , and foodstuff s which were of vital help to worlds in desperate need . Upon learning of this storage base , the Jedi High Council hatched a mission to seize the base and distribute the supplies to needy worlds . By seizing these supplies , the Jedi also planned to deny them to the Confederacy of Independent Systems . Jedi Master Mace Windu placed Masters Obi - Wan Kenobi and Quinlan Vos in charge of the mission . He also instructed the two masters to bring two other Jedi with them and enough Clone trooper s to transport the supplies . For this mission , Kenobi picked his former Padawan Anakin Skywalker and another Jedi Knight named Akar - Deshu , who was a friend of Vos . Unknown to the Jedi and Galactic Republic , Vos had turned to the dark side of the Force and was Count Dooku ' s secret apprentice . Vos had joined forces with Dooku in order to learn the identity of his secret Sith master Darth Sidious and destroy both Sith Lord s . To gain Dooku ' s trust , he supplied the Separatists with intelligence about the planned Jedi and Republic operation . The mission . Expecting resistance from Separatist starfighter s Kenobi , Anakin , Vos , and Desh flew to the asteroid base in their Eta - 2 " Actis " - class interceptors . Sure enough , six vulture droids emerged from the asteroid base to engage them . The Jedi starfighters quickly eliminated the droid fighters and managed to penetrate the tunnel leading to the base . There , the found a large stockpile of supplies . While Anakin , Kenobi , and Vos landed their starfighters , Desh returned in his Jedi starfighter to their " Arquitens " - class light cruiser to tell the clone troopers to bring transports . Before the Jedi could begin exploring or surveying the cavern , the Clone Commander Cody arrived with three transports . Before the Jedi and clones could begin loading the supplies , Vos discovered that the Separatists had rigged the entire asteroid to blow up . There was no chance of disarming them because there were at least six bombs and they all had been timed to explode in three minutes . Unable to disarm the bombs , the Jedi and clones were forced to abandon the asteroid storage base . They managed to escape minutes before an explosion ripped through the asteroid , destroying most of the supplies . Following the explosion , Master Kenobi instructed Desh to keep a single transport in the vicinity to search for any salvageable debris . Since the explosion had failed to shatter the asteroid . Kenobi thought that there would be some salvageable supplies there . While Desh stayed behind to salvage supplies , Kenobi , Skywalker , and Vos returned to Coruscant to inform the Council of the failed mission . Aftermath . To reward Master Vos for saving many lives on the failed asteroid salvage mission , the Jedi Council assigned him to lead an attack on a Separatist listening post on the planet Vanqor . However , Vos informed Count Dooku about the planned Jedi and Republic operation . As a result , the Separatists were able to evacuate the facility before the arrival of the Jedi and clone troopers . Suspecting that this incident was no coincidence , Vos ' Jedi colleagues and the Council came to suspect that they had a traitor was leaking information to the Separatists . Their suspicions of treason were confirmed when Desh uncovered evidence among the asteroid debris that the bombs were Republic - issue weapons . As a result , the Jedi deduced that there was a traitor within their ranks . While Windu suspected that Vos had planted those bombs , Kenobi urged for caution until they had enough evidence to either prove or disprove Vos ' treason . Agreeing with Kenobi , Yoda decided to talk with Vos in private . After Yoda discerned that Vos had indeed fallen to the dark side , the Council sent him on a mission to kill Count Dooku in order to test his loyalty to the Jedi and Republic . This led to the events of the Second battle of Christophsis .
