In 22 BBY , the Galactic Republic and Jedi Order sought to capture Confederate Head of State Count Dooku in order to bring the Clone Wars to a quicker end . High Jedi General Obi - Wan Kenobi and Jedi General Anakin Skywalker devised a plan to capture the Sith Lord : Skywalker would sneak aboard Dooku ' s frigate and purposely allow himself to be captured so that he could disable the ship ' s security systems and enable Kenobi to join him on the craft . In order to make his ruse appear convincing , Skywalker intentionally damaged his Delta - 7B starfighter with assistance from his astromech droid , R2 - D2 . General Skywalker then planned to be dropped off in his starfighter from his personal ship , the " Twilight " , in an ice field , where the Confederate frigate would find him and pull him aboard . The operation . Upon arriving in the ice field , Skywalker was deployed in his starfighter . Picking up the Jedi ' s life - sign , the Confederate frigate ' s battle droid captain ordered the Jedi fighter to be towed aboard . As B1 and B2 battle droids surrounded the starfighter , Skywalker exited his ship , and , wielding a fake lightsaber , fought the battle droids . After a B2 super battle droid destroyed the Jedi ' s weapon , the droids apprehended Skywalker , placing their prisoner in one of the frigate ' s holding cells . While Skywalker ' s Padawan , Jedi Commander Ahsoka Tano , returned with the " Twilight " to the cruiser , Kenobi donned a spacesuit to protect himself from the vacuum of space and infiltrated Dooku ' s frigate , which was in space near the planet Vanqor . Thanks to Skywalker ' s deactivation of the ship ' s security systems , Kenobi was able to board the ship through a hatch . Kenobi left his suit behind and used a burst of Force speed to sneak past a B1 battle droid manning one of the frigate ' s controls . Kenobi eventually located and freed Skywalker , returning his lightsaber to him , and the two Jedi found Dooku ' s quarters . As Skywalker and Kenobi confronted the Sith Lord , the Republic " Venator " - class Star Destroyer " Resolute " — being commanded by Tano and Clone Captain CT - 7567 — opened fire on Dooku ' s frigate . With his ship outgunned and targeted for boarding , Dooku dropped into an escape hatch and headed to his frigate ' s hangar . While Skywalker followed Dooku through the ship ' s interior , Kenobi left to cut the Sith Lord off in the hangar bay . Dooku shot Force lightning at Skywalker , and although the latter was able to deflect the bolts with his lightsaber , the glare caused him to lose sight of his quarry at a junction where the hatch took two different routes . Dooku arrived in the hangar bay and fled his frigate in his " Punworcca 116 " - class sloop . Kenobi entered the room in time to see Dooku depart with a Vulture droid escort . Kenobi dispatched several battle droids near a " Sheathipede " - class transport shuttle , stole the vessel , and was soon joined by Skywalker , who had found his way to the hangar . As the hangar door began to close shut , Skywalker took control of the shuttle and piloted the vessel out of the frigate in time to avoid being trapped . Kenobi told Tano to follow in whatever reinforcements she could find . Pursuing Dooku , Kenobi managed to land a shot on Dooku ' s solar sailer , forcing the count to crash - land on Vanqor . As the Vulture droid starfighters attacked the Jedi ' s stolen shuttle , Kenobi returned fire on the enemy fighters , but one of the droids hit the shuttle . The Jedi were forced to crash - land on Vanqor as well . Upon finding Dooku ' s ship with the Sith Lord nowhere in sight , Skywalker destroyed a homing beacon that Dooku had activated to call for help . Continuing their search for the Sith Lord , the pair of Jedi Generals entered a cave , sensing Dooku ' s presence , among several other lifeforms . Using their lightsabers for illumination , Skywalker and Kenobi looked for Dooku before the Sith Lord himself began a rockfall above the two Jedi . Kenobi jumped out of the way in time , but Skywalker was trapped beneath the stalactites . Dooku stole Skywalker ' s lightsaber and caused an avalanche as he left the cave , blocking the cavern entrance with the Force . As Skywalker freed himself from the rocks and found Kenobi , a gundark beast appeared and attacked Skywalker . Because Kenobi ' s lightsaber had been rendered defunct with its crystals knocked loose , he and Skywalker pelted rocks at the gundark with the Force , and the creature was eventually crushed . While telekinetically moving rocks to form a barrier between themselves and the fallen gundark , the two Jedi accidentally opened a fissure in the cave , releasing toxic gas that could kill them within minutes . Attempting to clear the blocked cavern entrance , Skywalker and Kenobi collapsed from the effects of the gas . The duo were saved when Tano and a squad of clone troopers — who had arrived on Vanqor aboard a " Nu " - class attack shuttle — blasted the entrance open . The explosion repelled the gas , and Skywalker and Kenobi were able to escape from the cave . With the two Jedi Generals freed , Tano ordered the clone troopers to seal the entrance once more as the gundark returned . Aftermath . While the Jedi were occupied with fighting the gundark , a gang of Weequay pirates tricked Count Dooku into traveling to the planet Florrum to escape the " dangers " that befell Vanqor after nightfall . On Florrum , the pirates managed to take Dooku hostage and took him to their outpost . Contacting Supreme Chancellor Palpatine , Hondo Ohnaka — the chief of the pirate band — set Dooku ' s ransom at one million credits . Senator Padmé Amidala requested that two Jedi be allowed to verify that Dooku was in the pirates ' captivity so that the Republic could finally apprehend the Sith Lord . Since Skywalker and Kenobi were in a system close to Florrum , Jedi Masters Yoda and Mace Windu assigned the two to the mission . The two Jedi Generals took the " Twilight " to the Outer Rim planet .
