Battle of Utapau The Battle of Utapau acted as one of the last decisive large - scale battles of the Confederacy of Independent Systems against the Galactic Republic in the Clone Wars , and was fought between the Separatist Droid Army and Grand Army of the Republic . After intelligence reports suggested General Grievous had fled to Utapau following the Battle of Coruscant , Jedi General Obi - Wan Kenobi and the 212th Attack Battalion were dispatched to deal with Grievous . After landing on Utapau alone ahead of the main clone force , Kenobi was directed by Tion Medon to the tenth level , where Grievous and other Separatist leaders were hiding . Kenobi , after waiting for the Separatist Councilors to leave , had the Republic forces move in and engaged Grievous in a fierce and lengthy duel , eventually shooting him to death . Not long after the general ' s death , Order 66 was issued to the clone troopers and Kenobi was forced to escape Utapau aboard Grievous ' own starfighter . Prelude . After three years of fighting , the Galactic Republic began to gain an advantage over the Confederacy of Independent Systems , many of whose high ranking leaders were captured or dead , with the most recent being Head of State Count Dooku . Republic Clone Intelligence soon managed to discover the location of General Grievous , who had succeeded Dooku as Head of State and informed the Jedi Council , who asked Jedi Master Obi - Wan Kenobi to lead the battle . After saying farewell to Anakin Skywalker , he organized a fleet of " Venator " - class Star Destroyers carrying an army of clone trooper s , led by clone Commander Cody . Kenobi arrived on Utapau in his Eta - 2 " Actis " - class interceptor under the pretense of refueling his ship . He was greeted by Tion Medon , the Port Administrator of Pau City , observed from a distance by one of Grievous ' MagnaGuards . Medon discreetly revealed information that the CIS were occupying the city and were forced to accept their presence by being held as hostages so that they could use Pau City as a hiding place for the Separatist Council , Grievous and his army of Battle droid s . Kenobi sent the droid R4 - G9 fly back to his fleet to inform the clones of the situation , but he stayed in city to engage Grievous . Kenobi commandeered a varactyl beast named Boga as a mount , and rode in secret to infiltrate the hangar of a modified Core ship and went onto a platform overlooking the hangar where he witnessed a meeting of the Separatist leadership . Where Grievous informed them that an attack by the Republic was expected , and was therefore moving them to the planet Mustafar where he claimed that they would be safe . Though Nute Gunray and the other Council members , began to doubt the abilities of their new leader to keep them safe , they nevertheless followed his orders , leaving just moments before Kenobi ' s arrival . The battle . Engaging Grievous . After the Separatist Council departed Utapau , Kenobi revealed himself by dropping from the catwalk above the hangar , and was immediately surrounded by battle droids and found himself confronted by four of Grievous ' IG - 100 MagnaGuard s . Kenobi defeated them quickly , using The Force to dislodge a cargo module hanging from the ceiling and crushed three of them , casually decapitating the sole survivor . Grievous ' s droids were preparing to open fire on Kenobi , but were called off as Grievous decided to challenge Kenobi himself . Drawing four lightsaber s at once , he then spun them rapidly in a buzzsaw motion and advanced on Kenobi . Kenobi slowly retreated before thrusting his lightsaber into the swirling energy blades , engaging Grievous in a spectacular , though brief , display of swordsmanship . Grievous remained unable to penetrate Kenobi ' s defense , so he ramped up his attacks even further . Kenobi was able to amputate two of Grievous ' robotic arms , as Kenobi ' s blade , instead of intercepting Grievous ' s blade , sliced the cyborg ' s left lower wrist . Staring in surprise at his smoking stump , Grievous lunged in another attack . After another brief bout of fencing , another of Grievous ' lightsabers , still clutched in his metal hand , bounced on the deck . Republic arrival . At that moment , Republic forces led by Commander Cody arrived , with Star destroyers pounding fire on Separatist defensive positions and round after round of Clone Troopers repelling from gunships . While the Clone Troopers were held back by Crab droids and other droid forces , Grievous prepared to resume the duel , advancing on his opponent . However , Kenobi Force pushed the general , sending him flying up and crashing against the ceiling . Dropping his two remaining lightsabers as he plummeted to the hangar floor , an unarmed Grievous chose to flee . Grievous crawled to his wheel bike and mounted it , speeding out of the hangar and dropping to the lower levels of the city , crushing everything in his path as he raced towards the docking platform where his private ship waited . Kenobi pursued on his varactyl , Boga , but lost his lightsaber after the jarring impact on the way down , the lightsaber eventually landing at the feet of Commander Cody who later informed the Jedi Council members about Kenobi ' s current pursuit and battle with Grievous , to which Mace Windu then had Anakin deliver the news to Chancellor Palpatine . Mace Windu and the other council members secretly voice their suspicions regarding Palpatine ' s intentions , with Windu mentioning the possibility that they ' ll have to remove Palpatine from office should he refuse to give up his emergency powers after the defeat of Grievous . Kenobi pursued Grievous in a furious chase through the streets of Pau City as the battle raged around them . As Kenobi caught up to the General , Grievous thrust at Boga with an electrostaff he stashed in the wheel bike . Kenobi managed to grab hold of the shaft of the weapon and wrench it from the cyborg ' s hands . Kenobi then attempted to destroy the wheels on Grievous ' s vehicle with it before attacking the General himself with it . Grievous managed to regain hold of it , and pulled it back , and Kenobi along with it . As the two grappled for control of the wheel bike , Grievous pulled out a blaster and attempted to shoot Kenobi , though the Jedi evaded the shots . Unfortunately , Kenobi ' s movements off - balanced the wheelbike , causing it to flip as they arrived at Grievous ' landing platform . While they were thrown off , the bike skidded off the platform and fell into the sink hole below . The end of Grievous . The two opponents recovered quickly , Kenobi brandishing the electrostaff against the blaster - wielding Grievous . Disarming the General , Kenobi began unleashing a series of jabs against the cyborg ' s torso , knocking Grievous over . Grievous retaliated with a kick that threw Kenobi across the platform . As Kenobi regained his feet , Grievous closed the distance , engaging Kenobi in a melee . While Grievous ' mechanical exoskeleton provided him with a clear advantage , Kenobi managed to pry apart the plates protecting Grievous ' s internal organs before being thrown to the ground . Kenobi counter - attacked by kicking Grievous ' s leg , but only injured himself against the hard durasteel . Grievous grabbed Kenobi by the collar and threw him across the platform , with Kenobi barely managing to grab onto the edge . Grievous retrieved the electrostaff and advanced on Kenobi to deliver the killing blow . Desperately hanging from the edge , Kenobi used the Force to summon Grievous ' blaster to his hand . Blasting through the gaps in the general ' s armorplast chestplates at the exposed organs , he ignited the tissue . Grievous ' s internal organs combusted violently , painfully killing the Separatist general . Grievous ' s death was later reported to the Jedi Council , with Mace Windu preparing to go to Palpatine ' s office to inform him of this development in the hopes that he lay down his emergency powers , until Anakin revealed Palpatine ' s stance as a Sith Lord . Continued fighting and Order 66 . After the death of Grievous , the droid army continued to engage the clone troopers as General Kenobi was rejoining the battle . The B1 battle droid 0D31 fired down from a platform on the road where Kenobi was riding , however was blasted by members of the 212th . Kenobi arrived to Cody ' s position and had his lightsaber returned to him before charging up a cliff ledge . It was then that Cody received a message from Darth Sidious , instructing him to execute Order 66 . Cody ordered an AT - TE to fire its main cannon at Obi - Wan , who was ascending the cliff heading up to the Separatist headquarters , who fell into the sinkhole below . Aftermath . Cody dispatched probe droid s to the sinkhole floor find the Jedi ' s body and ascertain whether he was dead or alive . Kenobi then used stealth to make his way back up to Pau City , get to Grievous ' s starfighter and escape Utapau . Behind the scenes . The Battle of Utapau first appeared in the 2005 film .
