Battle of the Kaliida Nebula / Legends The Battle of the Kaliida Nebula , also known as the Battle of Kaliida Shoals Medcenter , took place near the Kaliida Nebula in 22 BBY during the Clone Wars . Shortly after the Galactic Republic ' s discovery of the Confederate warship " Malevolence " , Jedi General Anakin Skywalker developed a plan to attack the warship and its commander , General Grievous . Confederate Head of State Count Dooku ordered Grievous to target the Republic ' s secret Outer Rim medical center , and the " Malevolence " eradication of a Republic medical convoy in the Ryndellia system identified the warship ' s quarry to the Republic . Skywalker planned to intercept the ship , accompanied by his Padawan , Jedi Commander Ahsoka Tano , as well as Jedi General Plo Koon . Skywalker arrived at the medical station via a shortcut through the nebula with the starfighter unit Shadow Squadron , and engaged Vulture droids launched from the " Malevolence " . Suffering losses from the warship ' s ion pulse cannon s , Skywalker led his squadron to attack the vessel ' s starboard cannon . When the " Malevolence " attempted to use the damaged weapon on the medical center , the cannon exploded , causing further damage to the ship . Admiral Wullf Yularen and High Jedi General Obi - Wan Kenobi arrived with several " Venator " - class Star Destroyers and engaged the fleeing " Malevolence " , which was unable to retreat to hyperspace because of damage to its hyperdrive . Dooku ' s Sith Master , Darth Sidious , used his alter ego as Supreme Chancellor Palpatine to trick Senator Padmé Amidala into traveling to the nebula , where Grievous could use her as a hostage and escape . Amidala arrived in the system and was pulled aboard the " Malevolence " . Skywalker and Kenobi arrived on the warship via Skywalker ' s personal ship , the " Twilight " , and rescued Amidala . Kenobi attempted to cause further damage to the warship ' s hyperdrive , but was confronted by Grievous and forced to engage the cyborg general in lightsaber combat before escaping . Skywalker and Amidala sabotaged the ship ' s navigation computer , and the group returned to the Republic fleet . When the " Malevolence " attempted to jump to hyperspace , it crashed into the Dead Moon of Antar , and Grievous retreated . Prelude . The mystery weapon . In 22 BBY , during the Clone Wars , the Confederacy of Independent Systems built a superweapon , the " Subjugator " - class heavy cruiser " Malevolence " , capable of defeating numerous Galactic Republic fleets with its ion pulse cannon s . The cannons neutralized all power to their targets , leaving their prey defenseless without the ability to use deflector shields and vulnerable to fire from the " Malevolence " laser cannons . Under the command of General Grievous , the Confederate warship began a series of strikes on Republic task forces that left no survivors to tell the Republic of the weapon or its methods of attack , leading the " Malevolence " to be dubbed the " mystery weapon " for its unknown nature . The attacks formed no pattern , and the unpredictability of future targets drove fear throughout the Republic . Jedi General Plo Koon of the Jedi High Council volunteered to lead a hunt for the mysterious weapon and took a fleet of several " Venator " - class Star Destroyers to the Abregado system , where the " Malevolence " had been located . On Grievous ' s order , the warship attacked the Republic fleet with its ion cannons , and the cruisers launched several escape pods . The Confederate Head of State Count Dooku was aboard the warship and ordered rocket battle droid s to eliminate the pods with boarding craft , not intending to allow the Republic to learn of the warship and its weapons . However , Koon and several clone troopers were rescued by Jedi General Anakin Skywalker and his Padawan , Jedi Commander Ahsoka Tano , and were able to escape the " Malevolence " , taking the knowledge of the warship to the Republic . Dooku , displeased with Grievous , left to discuss the general ' s failure with his Sith Master , Darth Sidious . Preparing a counterattack . Following the revelation of the superweapon ' s nature , Skywalker planned to lead a counterattack against the " Malevolence " with Shadow Squadron of starfighters . The Jedi applied for several BTL - B Y - wing starfighter s through Supreme Chancellor Palpatine and Senator Ask Aak , but discovered that they were still in the experimental stage . Skywalker also learned that the request had to come via a Galactic Senate Committee . Unable to obtain the bombers through official means , Skywalker traveled directly to the testing facility over the planet Bormus where the fighters were being manufactured . Arriving with Shadow Squadron aboard his personal ship , the " Twilight " , Skywalker took the bombers under the pretense that the request had come from Palpatine himself . Returning to his flagship , the " Resolute " , Skywalker developed a plan to lead Shadow Squadron on a direct attack on the " Malevolence " , believing that while the larger cruisers could not outmaneuver the warship , the bombers would be able to slip through the warship ' s defenses . The squadron ' s target was the " Malevolence " bridge , where General Grievous would be maintaining command . With the death of Grievous , Skywalker believed that the war could be brought to a quicker end . Skywalker began preparations for his departure , and was to be accompanied by Tano and Plo Koon , the latter of whom chose to fly in " Blade of Dorin " , his Delta - 7B starfighter . A new target . Count Dooku met with Darth Sidious and learned of the Republic ' s secret Outer Rim medical station , the Kaliida Shoals Medical Center , which was treating over 60 , 000 wounded Republic clones . As the " Malevolence " ambushed a Republic medical convoy in the Ryndellia system , Dooku contacted Grievous and ordered the cyborg general to target the medical center ; without the medical base , the Republic would have nowhere to send its wounded clone troopers . Grievous was pleased with this new assignment , as it showed that the count had not lost all faith in him since his failure to prevent the escape of the Jedi during the Battle of Abregado . The " Malevolence " eradicated the convoy and proceeded to jump to hyperspace ; however , as it was unable to pass through the nearby Kaliida Nebula , the warship was forced to take a longer route around to the medical center . As Skywalker learned of the convoy ' s defeat from Admiral Wullf Yularen , the Jedi deduced that the medical center was the warship ' s next target . Skywalker intended to take Shadow Squadron on a shortcut through the nebula in order to arrive at the medical station before the warship , and planned to attack the " Malevolence " before it could destroy the base . Admiral Yularen and High Jedi General Obi - Wan Kenobi resolved to take a hyperspace route around the nebula , planning to arrive at the medical center to reinforce Skywalker with several " Venator " - class cruisers , including the " Resolute " , as well as Kenobi ' s flagship , the " Negotiator " . Yularen warned the medical center ' s Kaminoan administrator , Nala Se , of the impending danger , and Kenobi contacted the people of the nearby planet Naboo ; several " Pelta " - class frigates were sent to help evacuate the medical center . Skywalker , Tano , Koon , and another Jedi Knight departed the Republic fleet with Shadow Squadron . Upon entering the nebula , they encountered several Neebray mantas , and Skywalker ordered the squadron to assume the single - file Bantha formation and follow him out of the nebula . Clone trooper pilot Matchstick ' s fighter was damaged , but the mantas did not cause any casualties apart from pilot Contrail ' s astromech droid . Shadow Squadron arrived at the medical center , located in the Ryndellia system , shortly before the " Malevolence " came out of hyperspace and approached the station . By this time , the medical center had evacuated half of its patients with the help of the " Pelta " - class frigates , but the clones being treated in bacta tanks were unable to be moved . The battle . Attack on the " Malevolence " . As Skywalker , Tano , Koon , the Jedi Knight — flying a Delta - 7B interceptor — and Shadow Squadron approached , the " Malevolence " attacked the fleeing " Pelta " - class frigates with its ion cannons . After the frigates had been eradicated , several squadrons of Vulture droids were launched from the " Malevolence " , and the droid starfighters attacked the incoming Shadow Squadron . Despite the fact that his own Vulture droids would be caught in the blast , Grievous ordered the warship ' s ion cannon to target the approaching Y - wing bombers . As the " Malevolence " fired its ion cannon , Skywalker immediately ordered his squadron to head for the top edge of the ray to avoid being neutralized . However , Matchstick ' s fighter malfunctioned , and his fighter crashed into fellow pilot Tag ' s bomber , while Shadow Six , Seven , and Ten , were caught in the ion ray . Even with its numbers cut in half , the Republic squadron continued toward the " Malevolence " and maneuvered through the incoming laser fire as the warship targeted the medcenter . Another of the Republic fighters had been destroyed , and Tano advised Skywalker that with their decreasing firepower , targeting the bridge was not their best option . Taking Koon ' s suggestion to obliterate the warship ' s primary weapon , Skywalker changed the target to the starboard ion cannon , and he , Koon , and the Jedi Knight spearheaded the attack on the cannon . After the cannon was hit by proton torpedoes , Grievous attempted to fire the weapon , but both cannons exploded , causing further damage to the ship and disabling the " Malevolence " hyperdrive . Kenobi ' s fleet of Star Destroyers arrived in the star system and directed laser fire at the Confederate warship . Unable to retreat to hyperspace , Grievous ordered the " Malevolence " to flee to Confederate - held space . Kenobi contacted Skywalker and congratulated him on his success , and Skywalker , Tano , Koon and the Jedi Knight went to the medical station to regroup and refuel their fighters to provide support for the Republic fleet . Mission aboard the " Malevolence " . When Dooku learned of Grievous ' failure , he was displeased , and his Sith Master , Darth Sidious , arranged a trap for an important Republic official that would provide an opportunity for Grievous to escape . Sidious , in the guise of his alter ego of Supreme Chancellor Palpatine , manipulated Senator Padmé Amidala into traveling to the nebula , under the pretense that she would be meeting with an InterGalactic Banking Clan representative that wanted to negotiate a treaty with the Republic . Amidala agreed and headed to the nebula in her H - type Nubian yacht with her protocol droid , C - 3PO . As the Republic fleet continued its attack on the fleeing " Malevolence " , Amidala arrived out of hyperspace in front of the " Malevolence " bow and realized that she had been led into a trap . Skywalker and Tano returned to the " Resolute " , and Skywalker contacted Senior Jedi General Luminara Unduli for support , but discovered that she was busy fighting Confederate reinforcements nearby . Admiral Yularen deduced that the warship ' s hyperdrive was damaged because the " Malevolence " was not attempting to flee to hyperspace . Taking advantage of the warship ' s vulnerability , Kenobi ordered all laser fire to be directed at the " Malevolence " bridge . The " Resolute " picked up the arrival of Amidala ' s yacht and contacted the ship , and Skywalker was dismayed to learn of Amidala ' s presence , as she was his secret wife . To protect the senator , the Republic fleet was forced to cease its laser fire at the " Malevolence " . Amidala ' s ship was pulled aboard the " Malevolence " with a tractor beam , as Grievous intended to use the senator as a hostage to ensure the warship ' s escape . To rescue the senator , Skywalker and Kenobi departed in the " Twilight " to infiltrate the " Malevolence " . Trapped in the main hangar of the warship , Amidala set her yacht ' s engines to self - destruct before escaping and hiding elsewhere with C - 3PO , intending to delay her pursuers . As Grievous arrived to apprehend the senator , the ship discharged , but the cyborg general survived the explosion and ordered a full search of the ship . While attempting to contact the Republic fleet from a communications panel , Amidala and C - 3PO were forced to hide from Grievous and a B1 battle droid patrol . The senator and her protocol droid learned that the damage to the warship ' s hyperdrive would require less time to repair than originally believed , and Grievous left to inform Dooku of the news while the droids continued the search for the senator . As Skywalker and Kenobi arrived on the warship , they encountered several B1 battle droids and eliminated them . Back aboard the " Resolute " , Tano and Koon again contacted Unduli for support , and Unduli stated that she was on her way to the nebula with reinforcements . Amidala contacted the Republic fleet , and Tano patched the communication through to Skywalker and Kenobi , who arranged to rendezvous with Amidala at a rail jet junction in the middle of the ship . Upon arrival at the junction , Amidala and C - 3PO were ambushed by a battle droid patrol , and the senator returned fire at the droids while she and her protocol droid backed toward the rail jets . Noticing the senator ' s blaster fire , Skywalker and Kenobi immediately ignited their lightsabers and Force Jump ed across rail jet cars , dispatching several battle droids on their way to the senator . Amidala and C - 3PO escaped onto separate rail jet cars , but a B2 - HA series super battle droid fired a rocket at the junction Amidala ' s car was approaching , and Skywalker used the Force to pull Amidala onto his car . Kenobi attempted to telekinetically retrieve C - 3PO , but the droid was caught on an oncoming car and headed off in another direction . Dual sabotage . Upon learning from Amidala the battle droids ' progress on repairing the hyperdrive , Kenobi elected to disable the hyperdrive while Skywalker and Amidala decided to sabotage the navigation computer of the " Malevolence " . Heading to the warship ' s bridge with the senator , Skywalker dispatched his astromech droid , R2 - D2 , to rescue C - 3PO . The astromech droid halted the protocol droid ' s rail jet car and led him back to the " Twilight " . Grievous , however , was able to intercept the transmission between Kenobi , Skywalker , and Amidala , and the cyborg general proceeded to the ship ' s hyperdrive room to ambush Kenobi . As the Jedi entered the room and approached the battle droids guarding the hyperdrive , droid reinforcements arrived alongside Grievous and targeted Kenobi . Using several droidekas against their comrades , Kenobi Force - pushed two of the droids at the approaching battle droids behind them , then used the remaining droideka ' s deflector shield as protection from incoming blaster rifle fire from Grievous . Evenly matched with Grievous , Kenobi chose to escape , forcing the remaining droideka at Grievous and fleeing . Knocking a B1 battle droid aside in frustration , Grievous ordered the remaining droids to guard the hyperdrive while he personally went to deal with Kenobi . As Kenobi left , he contacted Skywalker and Amidala , who were meanwhile fighting a patrol of several B2 super battle droids . Kenobi arranged to meet the pair back at the " Twilight " before their communications were jammed by the " Malevolence " droid crew . At the rail jet , Kenobi was pursued by Grievous and several battle droids . The general and the droids jumped toward the Jedi ' s rail jet car , but the battle droids were destroyed from an incoming rail jet . As Grievous approached , Kenobi noticed a large , mechanical arm hanging over the rail jet and used it to propel himself toward Grievous , landing a kick on the general . The Jedi and cyborg engaged in a duel before Kenobi fled to the front of the car . Grievous slashed at the Jedi , making Kenobi lose his balance , but the Jedi was able to escape onto a car below . Skywalker and Amidala arrived on the bridge of the warship and dispatched the droids that were repairing the " Malevolence " hyperdrive . Two super battle droids entered the room , and Skywalker quickly Force - pushed Amidala back into the turbolift before destroying the droids . Intending to reset the navicomputer ' s coordinates for the hyperspace jump , Skywalker hot - wired the warship ' s systems while Amidala hid the disabled droids in the turbolift chamber to erase any traces of the fight and evidence of the sabotage . Meanwhile , the Republic fleet prepared to attack the " Malevolence " once the Jedi returned with the senator , but with communications blocked , the cruisers were unable to contact Skywalker for an update of the mission ' s status . Finishing their mission , Skywalker and Amidala left the bridge shortly before more battle droids arrived to take command of the " Malevolence " . The Jedi and senator met up with R2 - D2 and C - 3PO , and at the airlock where the " Twilight " was docked , Kenobi arrived , pursued by several droidekas . Skywalker used the Force to hover crates and provide cover for Kenobi , and the Republic group boarded the " Twilight " and escaped . Destruction . By this time , the " Malevolence " had reached the Mid Rim ' s Prindaar system . The " Twilight " retreated to the Republic fleet , and Grievous gave pursuit in his fighter , " Soulless One " , accompanied by several Vulture droids . Aboard the " Resolute " , Koon ordered the Star Destroyers to open fire once more , and the cruisers regained their attack on the fleeing " Malevolence " . As Grievous landed a shot on the " Twilight " , Amidala took charge of the laser cannon ' s periscope controls and returned fire at the droid starfighters . The cyborg general ordered the " Malevolence " to flee to the Confederate base in Sector Four , stating that he would meet the warship there , and the " Malevolence " maneuvered for the jump to hyperspace . Amidala aimed a shot at " Soulless One " , and Grievous moved aside , forcing a Vulture droid to take the shot . As the " Malevolence " crew engaged the warship ' s hyperdrive , the navicomputer malfunctioned and directed the warship toward the Dead Moon of Antar . Dooku made contact with Grievous , stating that the " Malevolence " and the general himself were being awaited at the rendezvous point , but Grievous cut off the transmission and escaped to hyperspace . The warship ' s battle droid crew was unable to reset the navicomputer in time , and the " Malevolence " crashed into the dead moon , ending the threat that the Confederate warship had posed to the Republic . Aftermath . The destruction of the " Malevolence " earned a smattering applause from the crews aboard the Republic Star Destroyers . The dead moon of Antar became the resting place of the Confederacy ' s prized warship , and Grievous ' defeat at the hands of the Republic further shook Count Dooku ' s faith in him . It was the destruction of the " Malevolence " , in addition to a number of following defeats , that prompted Dooku to arrange a test for his general later in the war . Following the Battle of the Kaliida Nebula , which also became known as the Battle of Kaliida Shoals Medcenter , a clone trooper squad under the command of Clone Captain Lock was sent to the remains of the " Malevolence " to confirm that it had been built by Quarren Separatists at Pammant Docks . A piece of scrap with the insignia of the Free Dac Volunteers Engineering Corps , a starship - construction organization that was based out of Pammant , was recovered from the destroyed warship , but a circuit board that had not been manufactured by the Quarrens was also found amongst the debris . After the clone squad ' s return to Coruscant , the piece was sent to the Jedi Archives , and Jedi Master Ring - Sol Ambase was able to confirm that the board was built by KynachTech Industries , a worker force based out of his own homeworld . Master Ambase and the clone trooper squad were dispatched to Kynachi to follow the lead , unaware that they were heading into a trap set by the Dark Lord Darth Sidious . Eventually , the Confederacy decided to rebuild the " Malevolence " , and Grievous personally supervised the operation . Once Grievous and a battle droid squad had eluded the Jedi Knight who had participated in the initial assault on the " Malevolence " , they retrieved the necessary information from the ship ' s crash site on the dead moon of Antar . As Pammant Docks began to reconstruct the new " Malevolence " , the Jedi Knight pursued Grievous to Pammant and dueled both Grievous and Count Dooku himself . Behind the scenes . The Battle of the Kaliida Nebula was featured in the 2008 . As it was spanned out over several episodes , the battle was one of the series ' first major battles , appearing in the episodes " Shadow of " Malevolence " " and " Destroy " Malevolence " . " In addition , the battle completed a three - part story arc in the series centered around the Confederate warship " Malevolence " , which made its first appearance in the television series in the episode " Rising " Malevolence " , " as well as " " , an issue of the series ' that led into the episode . Several stories relating to the battle itself were featured in the online comic ; " " depicted Anakin Skywalker ' s acquisition of the Y - wing bombers for the battle shortly before " Shadow of " Malevolence " , " while " " portrayed Palpatine ' s deception of Padmé Amidala , leading into " Destroy " Malevolence " . " The " " video game featured Obi - Wan Kenobi ' s duel with General Grievous aboard the " Malevolence " . The battle was identified by name in the 2009 " " . In 2010 , the battle was featured in the " Starfighter " mini - game of the , which introduced a slight inconsistency with " Shadow of " Malevolence " . " In the game , Skywalker pilots a Delta - 7B interceptor during the initial attack on the " Malevolence " , while in the episode , Skywalker mans a BTL - B Y - wing starfighter with Ahsoka Tano . This article assumes that the latter ' s interpretation is correct . The 2011 non - canon ical video game " " featured the battle in its comical depictions of " Shadow of " Malevolence " " and " Destroy " Malevolence " . " The battle depicted the BTL - B Y - wing starfighters in use , and also featured the series debut of the characters of Padmé Amidala and C - 3PO . Although the 2012 " The Essential Guide to Warfare " claims that the battle takes place in 22 BBY , it was assumed at the time to be an error given the then - establishment of the series in 21 BBY or later . " The Official Star Wars Fact File " Part 24 cemented the battle ' s dating in 22 BBY .
