Battle of Kamino / Legends The Battle of Kamino , a key campaign of the Clone Wars , was fought for control of the planet Kamino in 21 BBY . Also known as the Invasion of Kamino or the Defense of Kamino , the battle occurred when the Confederacy of Independent Systems launched a massive assault aimed at crippling the Grand Army of the Republic ' s main cloning facilities in Kamino ' s capital , Tipoca City . Having collaborated during a thwarted attempt to invade Kamino several months earlier , rivals General Grievous and Dark Acolyte Asajj Ventress were assigned by Count Dooku to lead the Separatist attack on Kamino . Joining Jedi General Shaak Ti and Prime Minister Lama Su in coordinating the Galactic Republic ' s defense of Kamino were Jedi Generals Obi - Wan Kenobi and Anakin Skywalker who , unwilling to lose the vital cloning factories , brought their clone troopers of the 501st Legion to reinforce the Grand Army defenses . Ventress had already infiltrated Kamino by the time Grievous arrived to beleaguer the Republic ' s naval blockade with an invasion fleet of his own . Although Skywalker led the Republic ' s starfighter squadrons against the Confederate armada , the resulting space engagement only served as a cover for elements of the Separatist Droid Army to land on Kamino via re - entry capsule s disguised as starship debris . After being reassembled by Ventress ' s aqua droids in the ocean of Kamino , the Separatist " Trident " - class assault ships launched their troops against Tipoca City , and the Jedi and clones rushed to repel Grievous and the invaders . Ventress went after a DNA sample of the Grand Army ' s prime clone Jango Fett but was intercepted by Skywalker , who dueled the Dark Acolyte for the DNA sample . In a similar fashion , Grievous was confronted by Kenobi while spearheading a droid assault on Tipoca City ' s clone barracks . As the Separatist battle droids pressed further into Tipoca City , Kamino ' s elite Advanced Recon Commandos played a critical part in repulsing the enemy forces from the clone troopers ' homeworld . While Clone Commander Cody and Clone Captain Rex organized a defense of the barracks , Ti led other troops in pushing back the droids to Tipoca City ' s main hangar , where the invaders were eliminated . Ultimately , Grievous and Ventress failed to cripple Tipoca City as they had hoped thanks to the intervention of Kenobi and Skywalker , the latter of whom recovered the stolen DNA sample from Ventress . Skywalker attempted to have his clone troopers execute Ventress , but she escaped with Grievous aboard a Kamino flight pod . Despite heavy losses , the Jedi and clones were able to drive the Separatists from Kamino . Two 501st troopers , Fives and Echo , were awarded ARC trooper status for their performance in the battle . Prelude . Targeting Kamino . During the Clone Wars , the Wild Space planet Kamino , being home to the Galactic Republic ' s vital cloning facilities for the Grand Army of the Republic , remained a prominent target for the Confederacy of Independent Systems . The Republic Navy blockaded Kamino with a heavily fortified fleet as protection against the Confederacy , which hoped to cripple the Republic war machine and win a decisive victory in the galactic conflict by stopping the Republic ' s production of clone troopers at its source . Having failed to eliminate Kamino ' s cloning facilities early on in the war , the Confederacy staged another invasion of Kamino in 22 BBY , the first year of the war . With the Dark Acolyte Asajj Ventress serving as a spy on Kamino , Confederate General Grievous proceeded to the Kamino system with a massive invasion fleet . Yet he failed to silence Rishi Station , a Republic listening post monitoring enemy activity near Kamino , and the Republic Navy was subsequently warned of the impending attack . Although forced to retreat from the Rishi moon , the Separatists remained determined to eliminate Kamino ' s cloning facilities . In 21 BBY , only several months after their previous attempt , Confederate Head of State Count Dooku authorized another plan to attack Kamino , assigning rival commanders Grievous and Ventress to lead the invasion . While Grievous engaged the Republic blockade of Kamino , the Separatist fleet would be allowed to sustain heavy losses . Under that cover , the main invasion force of battle droids would be sent down to the ocean of Kamino aboard modules of " Trident " - class assault ships in re - entry capsule s . As the capsules would be disguised as debris from the destroyed starships , the Republic would not realize the deception until too late . Once the Separatist Droid Army was planet - side , Ventress — who was already on Kamino aboard her personal starship , the " Trident " — would have her detachment of aqua droids reassemble the assault craft for the attack on Kamino ' s capital , Tipoca City , where the main cloning facilities were located . As part of her espionage tasks , Ventress determined the exact locations of the clone trooper barracks and the DNA archive room in Tipoca City ' s Military Complex , both of which would be primary targets during their assault . While Grievous led the droid assault on Tipoca City , specifically focusing on the clone barracks , Ventress would steal a DNA sample of Jango Fett , the Grand Army ' s prime clone . With a copy of Fett ' s DNA , the Separatists hoped to uncover and exploit a weakness in the genetic code , with potentially catastrophic consequences for the Republic ' s clone troopers . Jedi reinforcements . To draw the Republic and the Jedi Order into their plan , the Confederacy allowed Republic forces to intercept an encoded transmission of Grievous and Ventress discussing their impending assault on Kamino . The communiqué was received aboard the " Venator " - class Star Destroyer " Resolute " , the flagship of Jedi General Anakin Skywalker and the 501st Legion of clone troopers , who were hosting High General Obi - Wan Kenobi aboard their Star Destroyer . After their crew decrypted the transmission ' s audio , Skywalker and Kenobi learned of the Separatists ' targeting of Kamino , and their respective clone officers , Clone Captain CT - 7567 and Marshal Commander CC - 2224 , were adamant about aiding the defense of their homeworld . Skywalker and Kenobi resolved to return to Kamino with the 501st Legion to notify the Republic defenses of the imminent attack and to provide extra protection against Grievous ' s battle group . Once they had transferred their troops to an " Acclamator " - class assault ship , Skywalker and Kenobi proceeded to Tipoca City with the 501st Legion , while Admiral Wullf Yularen took the " Resolute " to join the nine other " Venator " - class Star Destroyers in the Republic ' s blockade of Kamino . Upon their arrival in Tipoca City , Skywalker and Kenobi met with Prime Minister Lama Su of Kamino and High General Shaak Ti , a Jedi Master who had been stationed on Kamino as the Jedi General in charge of clone trooper training . Upon learning of the impending invasion , Su could not believe that the Separatists would risk pitting themselves against the fortified blockade of the world , though all of them took the threat seriously and made preparations to defend Tipoca City . Skywalker and Kenobi ' s troops from the 501st Legion disembarked from the " Acclamator " - class transport , and CT - 7567 and CC - 2224 — nicknamed " Rex " and " Cody , " respectively — took their men directly to the Military Complex , which was being prepared for the attack . In addition , the Republic ' s starfighter squadrons were mobilized to mount an air strike against a Separatist attack . Meanwhile in deep space , Grievous made his own final preparations for the assault , commanding his fleet of three " Recusant " - class light destroyers and ten " Munificent " - class star frigates from his command ship , a " Providence " - class carrier / destroyer . The re - entry capsules containing the landing force of battle droids and pieces of " Trident " - class assault ships were affixed to the main hulls of the " Munificent " - class star frigates as planned . The Separatists planned to attack Tipoca City first , while Grievous and Ventress were interested to meet each other on the battlefield for the first time , face to face . The battle . Distraction in space . Emerging from hyperspace , Grievous ' s invasion fleet entered the Kamino system . Aided by the T - series tactical droid TV - 94B , Grievous deployed his armada in attack formation Echo - 3 , with his " Recusant " - class light destroyer s spearheading the assault . As the enemy fleet began its offensive , the ten " Venator " - class Star Destroyers of the Republic blockade held their position and returned the heavy turbolaser fire , supplemented by a pair of " Arquitens " - class light cruisers as well as Skywalker and Kenobi ' s " Acclamator " - class transport . Commanding the Republic fleet with clone naval officer s from the bridge of the " Resolute " , Admiral Yularen was intrigued by Grievous ' s head - on assault , as such a move was odd for the Confederate general , and included the anomaly in a report to the command at Tipoca City . The update was received by Kenobi , Ti , Su , and Cody and Rex , who were overseeing the battle from the Military Complex ' s command center . As the Separatist armada pressed its attack , Cody had the Republic fleet shore up on defenses , while Ti — who had expected a larger invasion fleet — issued the order for the Republic ' s air strike . Kenobi meanwhile pondered why Grievous had forgone the element of surprise in favor of a direct approach for the attack . Responding to Ti ' s command , Skywalker led the Republic ' s starfighter squadrons — including his own personal group , Shadow Squadron , with clone pilot Broadside among them — from Tipoca City into space aboard his Delta - 7B " Aethersprite " - class light interceptor . Taking up position at the head of Shadow Squadron , Skywalker led groups of BTL - B Y - wing starfighter s and ARC - 170 starfighters against Grievous ' s opposing fleet , which responded by launching Vulture droid starfighters to combat the Republic squadrons . At the same time , V - 19 Torrent starfighters were marshaled in the defense of the Republic blockade from Separatist " Hyena " - class bombers . Skywalker worked with another Jedi Knight , who was also flying a Delta - 7B interceptor , to prevent the enemy ships from reaching the surface of Kamino . The two Jedi Knights spearheaded the assault on the frigates and destroyers of the Separatist armada , which quickly began to take heavy losses . The damage was intentional , however , as it allowed the re - entry capsules to detach from the frigates while giving credence to their cover as debris . To the Republic , it simply appeared that Grievous was sacrificing the frigates to protect his command ship . Grievous joined his aqua droids and B1 battle droids in the re - entry capsules and fell from orbit , through the atmosphere of Kamino , and straight into the waters surrounding Tipoca City , where they were received by Ventress . Once Grievous and his reinforcements had arrived , Ventress sent out her aqua droids to begin work reassembling the " Trident " - class assault ships in preparation for the assault on Tipoca City . Back in space , the Republic fleet and starfighter squadrons held strong against the Separatist armada and its defenses , which began to take a beating from the intense fire . Skywalker led Shadow Squadron into the heart of the battle , pressing his attack by focusing on the Separatist frigates . The offensive allowed more wreckage - disguised capsules to reach the ocean floor of Kamino , ready for reassembly . As the Separatist armada began to retreat from Kamino , Kenobi sensed through the Force that something was amiss , as not even Grievous would mount such a reckless attack on the blockade . Because Grievous knew that they had been ready to defend Kamino , Kenobi believed that the starship debris was key to uncovering whatever the Separatists were planning . To that end , he decided to take a single - seater submarine to investigate the downed starship wreckage , keeping in contact with Skywalker as he did so . It was not long before Kenobi discovered Ventress ' s aqua droids reassembling the " Trident " - class assault ships , many of which had already been completed by that time . Realizing the Separatists ' deception , Kenobi attempted to warn Skywalker and Ti of the underwater assault craft , but he was too deep for his signal to be transmitted . Shortly thereafter , one of the aqua droids noticed Kenobi ' s submarine and ordered him to stop . When a team of aqua droids clambered onto his ship and targeted its window and engines , Kenobi ejected from his submarine via an escape pod , but the aqua droids continued to pursue him . After being forced to abandon his escape pod , the oxygen - low Kenobi made for the surface , using the Force to call to a nearby aiwha for aid . With the help of the aiwha , Kenobi returned to the surface , gasping for breath . His relief was short - lived , as it was at that moment that Ventress led her " Trident " and the completed " Trident " - class assault ships out of the ocean to attack Tipoca City . As soon as Kenobi made him aware via comlink of the Confederacy ' s assault on Tipoca City , Skywalker ordered all of the Republic ' s starfighter squadrons back to the " Resolute " while he immediately made for the surface in his Delta - 7B interceptor . The Separatist fleet continued to retreat , though the battle over Kamino was no longer of concern to the Republic forces . The battlefield now became Tipoca City . Assault on Tipoca City . As the " Trident " - class assault ships moved into position to deploy their battle droid troops , Tipoca City was put on alert , and clone troopers rushed to defend the Military Complex . Clone Commander Colt was placed in charge of his fellow elite Advanced Recon Commandos who were assigned to the defense of Tipoca City , and they took up position within the Military Complex . While the defense of Tipoca City ' s main hangar was being organized , ARC Commander Havoc sent 501st troopers CT - 21 - 0408 and CT - 27 - 5555 , respectively nicknamed " Echo " and " Fives , " to take up sniper positions on the bridge connecting the hangar deck to the cloning factories . Another of the Advanced Recon Commandos joined his clone brethren in fortifying the main hangar just as several " Trident " - class assault ships clambered onto the facility . The assault ships rammed their drill - spike s into the walls of the hangar ' s roof , penetrating the building to deploy their battle - ready aqua droids . A furious firefight ensued in the hangar , with the clones attempting to hold out against the seemingly never - ending line of aqua droids . Having arrived in one of the assault ships , Grievous personally led the assault on the clones , ordering his troops to spare none of the Republic troopers . Several Advanced Recon Commandos , including ARC Commanders Havoc and Blitz , oversaw the defense of the main hangar against Grievous ' s invading troops . Maintenance clone 99 helped resupply the clones with DC - 15A blaster rifle s , though he was forced to abandon his post as the casualties around him mounted , particularly as Havoc fell to enemy blaster fire . Besieged by the " Trident " - class assault ships , Tipoca City began to take heavy damage , with a large amount of its factories ' cloning chambers breaking apart as explosions gripped the city . While Grievous pushed further into the Military Complex , Ventress led her aqua droids against clone troopers on the city ' s outer decks , with the Confederate assault ships going so far as to smash through the clones with their heavy leg units . Elsewhere , Grievous ordered another attack on Tipoca City , but Commander Cody and the Jedi Knight who had assisted Skywalker in the space battle over Kamino prepared a defense of the area . Cody had a series of platforms constructed in the ocean so that their forces could utilize tower - mounted blaster turrets against Grievous ' s battle group . The Republic detachment was supplemented by a number of Advanced Recon Commandos , who took up positions in bunkers along the Separatists ' intended path . Cody and the Jedi Knight were able to push back Grievous ' s initial force of battle droids and Armored Assault Tanks , and Grievous was forced to recall his forces to regroup for their next assault . Striking swiftly , Grievous bolstered his forces with shielded droidekas , BX - series droid commandos , and NR - N99 " Persuader " - class droid enforcer tanks , while he hoped to catch the clone detachment unprepared by deploying aerial droid - manned Single Trooper Aerial Platforms and droid starfighters . Nevertheless , Cody and the Jedi Knight held out against his attack , shooting down the dispatched Vulture droid starfighters and droid tri - fighters and prompting Grievous ' s forces to retreat a second time . With a storm brewing over Tipoca City , Grievous organized a final push against the Republic forces . While Cody and the Jedi Knight attempted to hold the line , Grievous had a number of " Trident " - class assault ships emerge from the ocean and land even more battle droids across the facility . After noticing that the Republic ' s rear defenses were weak , Grievous launched a surprise attack by ordering his assault ships to target a position well behind the Republic ' s front line , forcing Cody and the Jedi Knight to readjust their defenses . The Republic detachment ultimately prevailed over Grievous ' s battle group , and the Separatists recalled their forces from that battlefront . Yet the battle for Tipoca City was far from over . Across the Military Complex , young clone cadets were ushered to safety while their older brethren held out against the invading battle droids . With Shaak Ti and Lama Su coordinating defenses from the city ' s command center , Skywalker and Kenobi proceeded into the fray , leading a squad of clone troopers against a group of aqua droids . Both Jedi Generals soon came to the conclusion that there were not enough battle droids to capture the entire city . Realizing that the Separatists were distracting them , Kenobi resolved to confront Grievous while Skywalker proceeded to secure the DNA archive library . Echo and Fives fought on their own battlefront , defending the bridge from squads of aqua droids . 99 arrived to supply them with more ammunition , at which point Fives inquired if there was a better vantage point in the area . At that moment , four B1 battle droids ambushed them , but Fives summarily tossed one of 99 ' s thermal detonators at their attackers . What were thought to be more droids approaching through the smoke turned out to be five clone cadets who had been separated from their group en route to the barracks . Fives and Echo decided to escort them there , with 99 leading them on a shortcut through the city . In one of the city ' s hallways , Grievous pressed through clone defenses led by Commander Colt with a group of B1 battle droids . When the rest of his men fell to droid fire , Colt mounted a last stand against the battle droids , but he was interrupted by Ventress , who had arrived to rendezvous with Grievous . Ventress gripped Colt in a Force choke , then activated one of her lightsabers and pulled him onto her blade with the Force , impaling and killing him . Although Grievous was impressed with her display of power , Ventress had no respect for the cyborg general , refusing his offer for a droid escort on her mission to steal the clone DNA sample . Grievous meanwhile continued on to destroy the barracks , which would further seal a Separatist victory on Kamino . Republic retaliation . The Separatists continued to push back the clone forces across Tipoca City , with troops on the outer platforms losing ground . One squad of aqua droids breached the Military Complex ' s command center , where Ti , Su , and several clones were still overseeing the battle . Ti made quick work of the droids with her lightsaber , even destroying some of them by hurling them against a wall with the Force . She then ordered the Republic forces to push their offensive , as the droids were spread thin across the city . Fives , Echo , and 99 reached the barracks with their group of clone cadets , where Captain Rex and Commander Cody arrived to rally the young cadets to defend their homeworld . Fives and Echo also encouraged them to take up arms to protect their home . 99 brought Rex and Cody to the nearby armory to equip the cadets with weaponry for a defense of the barracks . The three of them returned with enough DC - 15S s for the cadets , whom Rex positioned in the barracks ' retractable sleeping chambers so that they could surprise the droids from behind . They were just in time , as Grievous arrived with his detachment of B1 battle droids and aqua droids . While the droids pressed into the barracks and began a firefight with Rex , Cody , and their men , Kenobi arrived to confront Grievous in the hallway outside , with the two rivals beginning a lightsaber duel . As he dueled with Kenobi , Grievous grabbed his opponent and threw him to the ground , then attempted to crush him beneath his mechanical feet . Kenobi managed to avoid the cyborg ' s powerful stamps , but he was then tossed against the ceiling and hit the ground hard . Although winded , Kenobi refused to concede to Grievous ' s assertion that Kamino had fallen , reaching out with the Force to slam Grievous against a wall . Taken off - guard by the offensive , Grievous retreated from the barracks , with Kenobi following close behind . Meanwhile , Ventress infiltrated the DNA archive room and stole a canister containing Jango Fett ' s DNA . Just as she secured her objective , Skywalker arrived , lightsaber in hand , to retrieve the DNA sample . The pair of familiar adversaries briefly reacquainted themselves before engaging in lightsaber combat . Ventress somersaulted over Skywalker and Force - pushed him against the DNA archive shelf , though Skywalker recovered quickly and re - engaged her . As their fierce duel moved into the hallway , Skywalker made a grab for the DNA canister on her utility belt , but Ventress was too quick for him and thwarted his attempt at retrieval . Skywalker responded by pressing his attack , driving Ventress backward before locking blades with the Dark Acolyte in an effort to overpower her . However , Ventress simply kicked Skywalker backward , taking advantage of his brief distraction to escape with the DNA canister , with Skywalker in hot pursuit . While the Jedi were pursuing the Separatist agents out of Tipoca City , Rex , Cody , Fives , and Echo mounted a defense of the barracks from the invading battle droids . The clones took up positions behind several crates to return the droids ' blaster fire , with 99 supplying Rex and Cody with thermal detonators to launch at the droids . Once the droids had passed the cadets ' hiding spots in the sleeping chambers , Rex commed the cadets to open fire on the droids , effectively surrounding the droids and locking them in a crossfire . Cody soon used up their supply of thermal detonators , at which point 99 opted to restock their explosives from the armory . As 99 abandoned his cover behind the crates , much to his fellow clones ' alarm , one of the droids ' blaster shots caught him in the leg . Desperate to protect their injured comrade , Echo and Fives increased their blaster fire , with Fives forgoing his cover to eliminate the droids with his heavy blaster rifle . Yet 99 took two more shots , this time fatal , to his back . The battle left no time for the clones to mourn their fallen comrade , as Cody received word from Ti that the rest of the droids throughout the city had been pushed back to the main hangar . Ti entered the fray in the hangar , joining the Republic troops in battling the remaining groups of aqua droids . With Kenobi trailing him , Grievous reached one of the outer landing platforms and climbed onto its underside , surprising Kenobi from behind once he arrived . As Grievous and Kenobi circled each other , a " Trident " - class assault ship clambered onto the platform , and the droid gunship used one of its leg units to compromise the platform ' s supports . Kenobi fell toward the sea many meters below , while Grievous reached an adjacent platform . Believing that Kenobi had drowned , Grievous boarded a Kamino flight pod to retrieve Ventress , unaware that Kenobi had summoned the aiwha that had saved him earlier to be pulled out of the water . In the main hangar , Ti and her men continued to cut through the trapped droids , with the clones using blasters , Z - 6 rotary blaster cannons , and RPS - 6 rocket launchers to annihilate the remaining assault ships . Once their hold on the hangar wall was compromised , the drill ships tumbled into the ocean below . On the outside platforms , ARC Commander Blitz led a squad of Advanced Recon Force troopers to target an assault ship that was about to penetrate a city wall with its drill - spike . Blitz had one of his troopers fire a rocket at the craft , causing it to crash onto a platform below . The compromised Trident drill fell in the path of Ventress , who was being pursued by Skywalker onto the outer decks . Dueling furiously , both adversaries avoided the ship and paid it little attention . A number of nearby clone troopers caught sight of Skywalker and went to his aid just as he kicked Ventress to the ground , then used the Force to retrieve the stolen DNA canister . The infuriated Ventress immediately retaliated , forcing Skywalker backward and knocking him to the ground before pulling the canister toward her with the Force . At that moment , the clone troopers arrived to assist Skywalker , and one of them grabbed the DNA sample in mid - air before it could reach Ventress . Now outnumbered by Skywalker and his men , the Dark Acolyte expected to be forced to surrender , though Skywalker intended to have the clones execute her on sight . Receiving a signal that Grievous was approaching in their escape vessel , Ventress refused to submit and unleashed a powerful Force repulse , knocking the Jedi and clones off their feet . Dodging the clones ' blaster fire , Ventress jumped aboard Grievous ' s craft . The rival Separatist commanders escaped from Kamino , neither of them having completed their objective . The remaining Separatist forces in Tipoca City were routed , resulting in a Republic victory . Aftermath . The Battle of Kamino , as it came to be called , became known as one of the key campaigns of the Clone Wars . It was also referred to as the Invasion of Kamino and the defense of Kamino . The death of 99 during the battle saddened many of his clone brethren ; in the words of Commander Cody , the Grand Army lost a true soldier that day , for 99 had a warrior ' s heart despite his malformation as a clone . Although the Confederacy had failed to cripple the cloning factories or steal a sample of Jango Fett ' s DNA , they left extensive damage to Tipoca City , particularly to a number of cloning chamber towers . Following the Republic ' s victory , the clone cadets and troopers of Tipoca City , supervised by several Advanced Recon Commandos , set to work restoring the Military Complex , as well as recording the large amount of casualties and taking the injured to receive medical treatment . Additionally , some of the Kaminoan cloners set to work assessing the damage to the main hangar . For their display of valor in defending Kamino , Fives and Echo were promoted to the rank of ARC trooper by Cody and Captain Rex . Having been squadmates in Domino Squad during their training , the two 501st troopers were honored to become the Grand Army ' s newest Advanced Recon Commandos . Jedi who participated in the Battle of Kamino recorded their experiences in datafiles that were published in the collection known as the Jedi Battle Logs . Behind the scenes . The Battle of Kamino was created for the and was featured in the episode " ARC Troopers , " which aired on September 17 , 2010 as part of the series ' premiere . Prior to then , the battle was featured in promotional material for the season in April 2010 and was confirmed in " Star Wars Insider " 120 . " ARC Troopers " served as a sequel to " Rookies , " an episode from the series ' that focused primarily on such clone trooper characters as Captain Rex , Commander Cody , Fives , and Echo . Originally , the Battle of Kamino was to have immediately followed the battle at Rishi Station depicted in " Rookies , " but it was moved farther down the timeline to allow Fives and Echo to have more experience prior to their promotion to ARC troopers . The battle featured the debut of the aqua droids , an aquatic battle droid model developed for the series . A September 18 , 2010 update to the depicted the battle in the mini - games " Republic Defender " and " Starfighter , " in addition to attributing the battle its official name . During production for the space portion of the battle , Series Supervising Director Dave Filoni made sure to have the episode ' s director , Kyle Dunlevy , raise the bar in terms of its scale . In keeping with established " Star Wars " canon , the battle was written so that Anakin Skywalker would not encounter General Grievous , as the film established that they were introduced to each other at the later Battle of Coruscant . A scene of Asajj Ventress Commander Colt on the cheek just after killing him was removed from the episode due to insistence from Cartoon Network ; the sequence was included in the episode as part of the DVD release . Grievous and Ventress ' s meeting during the battle represented a retcon to previously established continuity from the Expanded Universe , as it was stated to be their first face - to - face meeting despite the fact that such an encounter had already been depicted in the short comic " Rogue ' s Gallery " in 2005 . " Star Wars Insider " 125 ranked the Battle of Kamino alongside the earlier Battle of Christophsis , the Battle of Ryloth , and the Second Battle of Geonosis as one of the largest battles depicted in the series . In April 2012 , " " placed the battle within a timeline of the series ' events , between the events of the episodes " Sphere of Influence " and " The Mandalore Plot . " The battle ' s placement was revised in the 2013 " " , which moved it between the events of " Assassin " and " Sphere of Influence . " Inconsistencies . Visible in the Tipoca City command center scenes in " ARC Troopers " is a hologram of a trio of " Lucrehulk " - class Droid Control Ships that are part of Grievous ' s fleet . However , since they do not appear in the space battle scenes , this article assumes this is an animation error . The portrayal of the Battle of Kamino in the young readers ' novel " " differs in numerous places from the battle ' s depiction in " ARC Troopers . " In all cases , this article follows the episode ' s presentation of the battle . In " Defenders of the Republic " , Skywalker , Kenobi , and their men travel to Tipoca City in a Republic shuttle instead of an " Acclamator " - class transport . After the invasion of Tipoca City begins , Skywalker is assigned to take some of the young clone cadets to a secure location to wait out the fighting . He eventually comes upon Fives , Echo , and 99 on the bridge , and the three clones decide to take the cadets to the barracks while Skywalker departs to protect the DNA archive library . This is not the case in the episode , in which the cadets are separated from their group and come across Fives , Echo , and 99 on their own without Skywalker . Just prior to Grievous ' s rendezvous with Ventress in Tipoca City , some advanced clone cadets concentrate their fire on a nearby " Trident " - class assault ship . Ventress makes her entrance by killing the cadets instead of Commander Colt in the episode . For the defense of the clone barracks , the book depicts a larger number of clone cadets — an " army " — serving under Captain Rex and Commander Cody , whereas in the episode the cadets only amount to five . Rex does not instruct the cadets to take up position in the sleeping chambers ; the clones engage the battle droids from one direction for the entirety of the firefight . While assisting in pushing the droids back to the main hangar , Shaak Ti protects a group of inexperienced cadets from a large octuptarra magna tri - droid , which she charges and destroys . Immediately thereafter , Ventress arrives in the hangar with Skywalker in pursuit instead of on one of the outer platforms . ARC Commander Blitz is present in the hangar and orders his men to fire at Ventress , who deflects the blaster fire . On the other hand , the episode depicts Blitz on an outer platform , where he has one of his ARF troopers fire a missile at a " Trident " - class assault ship . Non - canon history . " " published an Infinities version of " ARC Troopers " in which the Battle of Kamino is depicted differently . In that version , Skywalker confronts General Grievous on an outer landing platform , while Obi - Wan Kenobi intercepts Ventress at the DNA archive room . During his duel with Ventress , Kenobi slices off her right arm and Force - pushes her other lightsaber out of reach , allowing her to be taken prisoner by a squad of Advanced Recon Commandos . Meanwhile , Skywalker fiercely duels Grievous and eventually manages to sever all four of his mechanical arms , and the cyborg is taken into custody alongside Ventress . Following the battle , Grievous refuses to submit to Jedi interrogation and is imprisoned by the Jedi High Council in the deepest level of the galactic capital of Coruscant , left in his dismembered state . The Jedi Council also attempts to bring Ventress back into the light , seeing if they can purge her anger so that she might be able to offer intelligence on Count Dooku ' s Sith Master , Darth Sidious .
