Battle of Christophsis The Battle of Christophsis took place for control of the planet Christophsis during the Clone Wars . Wanting to gain control of the planet ' s strategic resources , the Separatist Droid Army , led by General Whorm Loathsom , invaded and captured Christophsis . Responding to a cry for help from the world ' s inhabitants , the Galactic Republic and the Jedi High Council dispatched Jedi General s Obi - Wan Kenobi and Anakin Skywalker and Admiral Wullf Yularen with a clone trooper contingent from the Grand Army of the Republic to liberate the planet . After managing to break Confederate Admiral Trench ' s massive naval blockade of the planet and delivering supplies to Senator Bail Organa ' s refugee camp on the surface via an experimental stealth ship , the Republic forces attempted to ambush the Confederate battle droid army from a business center in one of the plazas of the capital city . Acting on information from one of its spies , Clone Sergeant Slick , the Separatists foiled the Republic ' s attack . Despite the turn of events , the Jedi and clones managed to escape and retreated back to their base . Alerted to the possibility of a spy within their men , Skywalker and Kenobi went to search for more information behind enemy lines while Clone Commander CC - 2224 and Clone Captain CT - 7567 — nicknamed " Cody " and " Rex , " respectively — stayed at the base to discover who the agent was . Upon arriving at the Separatist base , Skywalker and Kenobi confronted the Sith acolyte Asajj Ventress and discovered the presence of an invasion force in far greater strength than they had originally believed . Back at the Republic base , Slick was revealed to be the spy and managed to sabotage the Republic ' s weapons depot , destroying most of the Republic ' s supplies , before Rex and Cody apprehended him . Raising the stakes with its full strength , the main body of Confederate troops launched an assault on the Republic forces . After several days , the Republic managed to force the Separatist forces into a retreat . When Loathsom mounted a second assault , his forces ' advance was halted by the Republic ' s heavy cannons , and he and his droids pulled back to their base to set up a deflector shield to counter the Republic ' s artillery . The renewed Separatist blockade of Christophsis drove Yularen and the Republic fleet away from the planet , but Skywalker ' s newly assigned Jedi Padawan , Ahsoka Tano , was able to land on the world . Loathsom and the Confederacy mounted yet another assault , this time advancing behind their shield , which effectively neutralized the clone ' s artillery . While Kenobi , Rex , and 501st Legion troops defended the heavy cannons , Skywalker and Tano went to sabotage the Confederacy ' s shield generator . After Kenobi faked a surrender to Loathsom to gain time for his comrades to complete their mission , Skywalker and Tano were able to destroy the shield generator . Yularen returned to the system with Jedi Grand Master Yoda and a reinforced fleet and broke through the Separatist blockade , driving the enemy blockade away from Christophsis . In addition , the Republic ' s renewed artillery usage proved instrumental in annihilating the Separatists in the capital . Kenobi captured Loathsom , and the Republic emerged victorious and landed further reinforcements to secure the victory . Prelude . Several months after the Battle of Geonosis , Count Dooku and his Confederacy sent their Droid Army under General Whorm Loathsom and assassin Asajj Ventress to capture Christophsis , due to its strategic position on the Corellian Run and resources , while Admiral Trench blockaded the planet with a fleet of 30 warships to prevent Republic forces from liberating the world . During this time the Republic had sent a relief force under Senator Bail Organa to aid the people of Christophsis , who had become trapped due to the invasion . The Christophsians eventually were forced to plea with the Republic for help , due to worsening conditions and depletion of supplies . The Republic decided in favor of this due to the pleas and Organa ' s worsening situation . The Republic dispatched Jedi General s Anakin Skywalker and Obi - Wan Kenobi to disrupt the blockade and deliver Senator Organa ' s relief supplies . They eventually decided to send Skywalker ahead with a fleet of Star Destroyers with Kenobi and Clone Commander Cody , following behind in Kenobi ' s flagship , the " Negotiator " . Kenobi also decided to bring along an experimental stealth ship with cloaking abilities . However , the Separatists had a much larger army present than the Republic believed . In addition , Sergeant Slick , who was among the troops to be brought to Christophsis , had grown disillusioned with the Jedi and the Republic , believing that the clones lives as soldiers was little more than enslavement . Infuriated , he would pass vital info to Asajj Ventress when on the planet , and would be paid for his assistance . The Battle . Republic Arrival . Attack on the Blockade . When they arrived in Christophsisian space , Skywalker , Yularen , and their fleet - consisting of 3 " Venator " - class Star Destroyers - engaged the Separatist blockade , against Kenobi ' s orders . However , Trench ' s forces quickly outnumbered the Republic fleet , consisting of " Munificent " - class star frigates , Droid Control Ships , and Trench ' s " Providence " - class dreadnought flagship , " Invincible " . On the Star destroyer " Resolute " , Skywalker and Yularen managed to contact Senator Organa on the surface ; his position was being overrun by Separatist forces , and they were running low on food , water , and munitions . He and his men were close to being overwhelmed by the army on the surface when the transmission cut off , as one of Skywalker ' s cruisers was hit by enemy fire . As the two sides exchanged heavy fire , the " Invincible " advanced on the " Resolute " unopposed . Yularen ordered the " Resolute " forward shields activated just before the Separatist Command ship released a barrage of laser fire at the whole task force . Trench also attacked the " Pelta " - class frigates , separating them from their escort cruisers . One of the supply ships was hit by the increased fire , being blasted to bits . In response , Skywalker ordered all reactors to be overfired , intending to charge past the Separatist commander , though he was still unaware of his identity . At that point , Kenobi and Cody arrive on board the " Negotiator " behind Skywalker ' s ships , staying close to Christophsis ' moon . Though his tactical droid , TI - 99 , informed him that the " Resolute " was not breaking off its attack , Trench held his ships in line and had his bridge crew intensify forward shields . As their ship took more fire , Skywalker and Yularen holographically counselled with Kenobi . At his friends ' request , Skywalker decided to regroup behind the moon , ordering the supply ships to break away first , with the Star Destroyers covering their escape . His cruisers managed to maneuver around and have their hulls take most of the enemy fire , protecting the supply ships and the fleet behind them . Knowing his orders were to simply blockade the planet , Trench , in the belief that he had won the first round of the battle , decided against pursuing the retreating fleet and remained in orbit to wait for the Republic ' s inevitable second attack . To ready his ships for this , he had his command ship ' s shields recycled and forward cannons reset to a full charge . With the Republic fleet recuperating and waiting for the next attack , Skywalker took a " Nu " - class transport to the " Negotiator " , where he met Kenobi to see the ship the general had brought . After he had shown Skywalker the prototype ship and it ' s stealth capabilities , Kenobi said the ship was completely undetectable to scanners as far as they could tell , but this was it ' s first true field test . Skywalker , despite the ship ' s size , believed he could use it to take out the blockade from behind , Kenobi instead instructed him to use it to run a mercy mission to drop off supplies at Organa ' s camp . Though he wished to attack and destroy the blockade instead , Skywalker agreed to carry out the mission . Meanwhile , onboard the " Resolute " , Yularen was researching the markings on the " Invincible " , having noticed a familiarity with the tactics of the earlier battle . He found that it did indeed belong to Admiral Trench , a foe he had previously faced and presumed to be vaporized in the Battle of Malastare Narrows . Concerned , he requested that Skywalker delay his mission and met with the general aboard the " Negotiator " , reporting his findings to him while the stealth ship was being loaded . Because he had engaged the admiral previously , Yularen volunteered himself as consort on Skywalker ' s mission , believing it would be beneficial in the inevitable encounter with Trench ' s wit . Skywalker accepted and welcomed him to the mission . Stealth mission . With Clone Commander Blackout and trooper CT - 1284 , nicknamed " Spark " — the last of the stealth ship ' s crew — on board , at their stations , and ready for takeoff , the stealth ship powered up and prepared to depart . Skywalker pilot ed the ship out of the " Negotiator " main hangar bay and toward the heavily armored Separatist blockade , activating his craft ' s cloaking shield just as it came out from behind the moon . Remaining undetected by Trench and the rest of his fleet , Skywalker and Yularen slipped right past an ignorant " Munificent " - class frigate — close enough to leave Yularen worried about alerting the enemy to their presence . Conferring with his tactical droid aboard the " Invincible " , Trench found that Christophsisian resistance was crumbling , and the droid offered his estimation that it would be a half rotation more before it was completely over . Intending to add some pressure on those who had been sent to rescue Senator Organa , Trench dispatched his " Hyena " - class bombers to attack the senator ' s camp on the surface in order to draw his enemies out from behind the moon . The squadron of bomber s , accompanied by fighter escort , launched from the Separatist fleet , and their path to the surface inadvertently lead them straight to Skywalker ' s stealth ship , despite Trench ' s continued unawareness of the craft . The approaching bombers presented Skywalker with a tough decision to make : because he did not know if the Separatists had learned of their presence , he was uncertain if the bombers were targeting the stealth ship or not . The Republic craft itself was armed with proton torpedo es and anti - aircraft cannon s , but would have to de - cloak to use either weapons — and doing so would tell the Separatists they were there if they did not already know . Yularen noted that an offensive had to be mounted soon , if Skywalker decided to do so . As the diving bombers entered within range , Skywalker elected to chance that the blockade was unaware of the stealth ship and thereby ordered his crew to keep the ship cloaked , power the it down , and let her drift . Despite Yularen ' s belief to the contrary , the bombers did not attack the stealth ship , zooming right by and rattling it but otherwise leaving it unscathed . However , Yularen pushed away the comforting revelation that the Separatists were oblivious to their presence and voiced his realization that the bombers were heading to bomb Organa ' s command center . The bombers did just that , releasing their explosives on the senator ' s camp in the city . With the Separatists approaching both by air and ground , Organa opened a transmission to Kenobi and told him that without reinforcements , there was not much chance for survival . Kenobi then contacted Skywalker and told him to continue with his mission while he himself engaged Trench ' s fleet with the remaining ships of the task force . Both Yularen and Skywalker disagreed with this course of action ; Yularen stated that Kenobi did not have the proper resources to openly engage Trench and asserted that it was a trap , while Skywalker affirmed that the proposed tactic simply would not be successful . Believing that their ship was in the best position to attack Trench , Skywalker , to the surprise of Yularen , had four of the stealth craft ' s proton torpedoes prepped , intending to go on the offensive and divert Trench ' s attention from the Christopsisians and back to the Republic fleet . He then cut off Kenobi ' s transmission before he could continue to order Skywalker to deliver the supplies to the surface . Trench , meanwhile , found the Republic fleet ' s silence odd and mused to himself about their intentions . He soon found out , as Skywalker brought the stealth ship around to get a clear shot at Trench ' s ship . After disengaging the ships cloaking shields , Skywalker had his crew fire the four prepped torpedoes at the " Invincible " bridge . Trench managed to put up his ship ' s Thermal shield , rendering the attack unsuccessful . When the stealth ship began to re - cloak , Trench fired four missiles at the stealth craft . Skywalker decided to have his pilot launch decoy flares to intercept the missiles , and then re - cloaked the ship . Not to be deterred , Trench ordered a large spread of lasers fired at the ship ’ s last known position , believing he would be able to hit the craft with the sheer number of blasts . In spite of this , Skywalker managed to avoid the laser spread . This did not go unnoticed , as Trench surmised that since no clone pilot would have been able to avoid that many lasers , he must be dealing with a Jedi . Deciding to speak with his adversary , Trench patched himself over an open frequency and called out to his unseen enemy . Skywalker picked up the transmission and unhesitatingly accessed it , witnessing Trench goading the Republic forces into attacking him and boasting that he had dealt with cloaked ships before . After he had terminated his transmission , Trench was not surprised with his tactical droid ' s calculation that the Jedi would not turn back as he requested and theorized that the Jedi would attack again . Meanwhile , Skywalker and Yularen were left puzzled with the revelation of Trench ' s experience with cloaked ships until Kenobi obtained records of Trench ' s past battles . Kenobi reported that Trench had indeed faced such technology and had successfully hit them with tracking torpedoes , though nothing as small as the stealth ship . Skywalker correctly theorized that Trench had homed in on the ship ' s magnetic signature as a means of targeting the cloaked ships . Skywalker requested that Kenobi hold off his attack until Trench had been destroyed before ending the transmission . After completing the necessary preparations , the stealth ship de - cloaked once more and fired four more torpedoes at the " Invincible " . While the torpedoes hit the " Invincible " thermal shields and failed to do any damage , the bridge crew locked onto the stealth ship ' s magnetic signature and was able to track it . Having to lower his shields in order to fire tracking torpedoes , Trench had his tactical droid do just that and released the four - torpedo volley . With the bait taken , Skywalker began to pilot the stealth ship toward the Invincible . With the torpedoes following closely , Skywalker deactivated his ship ' s cloaking device and diverted all the ships power to her engine s . He then steered the ship straight towards the " Invincible " bridge . Realizing his error , Trench attempted to raise the thermal shields , but could not because they were still charging . Skywalker piloted the ship across the " Invincible " hull , grazing it and leading the tracking torpedoes straight towards the bridge . As the " Invincible " exploded behind him ( though Trench only lost an eye and three arms ) , Skywalker made for the planet ' s surface . Giving Skywalker a grudging congratulations , Kenobi engaged the remainder of the blockade with the " Negotiator " , while the stealth ship continued to the surface to deliver it ' s supplies . Skywalker and Yularen landed at the refugee camp and unloaded their supplies . Organa thanked the general for the lives he saved , and Yularen expressed his impressed view of Skywalker ' s unusual tactics . With Trench out of the way , the Separatist fleet was in disarray , and Kenobi pushed his fleet of " Venator " - class Star Destroyers forward to break the enemy blockade , which — in the absence of the " Invincible " — was now comprised of " Munificent " - class frigates and Droid Control Ships . Skywalker temporarily returned with Kenobi to pilot their respective Jedi interceptors against the remnants of the blockade . With that part of the battle won , they set up a base on the ground for their artillery , gunships and AT - TEs . Traitor in the ranks . Failed ambush . Kenobi and Cody joined Skywalker ; Clone Captain CT - 7567 , nicknamed " Rex ; " and the rest of the Republic forces on the surface in the capital of Chaleydonia , while Yularen eventually returned to the fleet as its acting commander in the continuing struggle against the Separatist blockade . Kenobi , Skywalker , Cody , Rex and their men then planned an ambush on column of battle droids and Armored Assault Tank s from two towers . Kenobi , Cody , and Slick stationed their men in the south tower , while Skywalker and Rex were based in the parallel north tower . While Separatist battle droids and AATs passed through the plaza below , Kenobi ' s men set up several blaster cannons , ready to ambush the advancing enemy forces . As the clones kept watch on the droids , however , the column of droids unexpectedly split into two . B1 battle droids took a turbolift up to the level of the south tower where Kenobi ' s forces were positioned and ambushed them , surrounding and converging on the clones . The backfired ambush made it apparent to Kenobi that their tactic had been compromised . Watching the transpiring events from the north tower and confirming the situation over comlink with Kenobi , Skywalker contacted clone pilot Hawk and ordered an evacuation from the south tower . Skywalker then cut through the window overlooking the plaza with his lightsaber and used the Force to blast a hole through it , enabling his men to fire their blaster rifles ' ascension cable s across to the south tower . Skywalker , Rex , and the clone troopers crossed the divide and sustained minimal casualties from the battle droids that opened fire on them from the plaza below . Rex , Skywalker , and their men met up with Kenobi in the south tower and cut off battle droids attempting to assault him from behind , and Kenobi telekinetically threw one of the blaster cannons at the droids , momentarily halting their advance . The Jedi and their respective forces entered a turbolift in order to evacuate from the roof of the tower , while droids pursued them in other lifts . After reaching the roof , the clone troopers provided cover fire so the Jedi could attack the droids at close range . Soon after , however , the tactical droid TJ - 55 came to the roof with droid reinforcements . Just then , Hawk ' s gunship arrived and hovered close to the roof of the tower . Continuing to fire at the droids , the troopers began to back into the craft . Before retreating , trooper Gus charged TJ - 55 and broke the droid ’ s head off , taking it into the gunship . Republic forces then left the failed ambush site and returned to the base , where Rex and Cody performed a robolobotomy on the tactical droid ' s head , managing to access its memory banks . The droid ' s head confirmed the Separatist forces had known of the Republic ' s strategy and position , but shut down before revealing anything else . When the clones reported their findings to their generals , Skywalker thought that a breach in security systems had been the source for the Confederacy ' s acquisition of the plans . Kenobi went as far as to suspect that their was a spy in their midst , thinking that they need to act behind enemy lines to find any relevant intel . Before leaving with Skywalker to investigate , Kenobi told Cody and Rex to keep the mission a secret , and to stay and track down and arrest the spy . As Kenobi and Skywalker left , Cody then saw that someone - Slick , though he did not know it at the time - had left their comlink on in the room and had been listening to the whole conversation . Rex and Cody then spotted Slick in the hallway , but he was too far away for them to identify him . Slick ran , and Rex and Cody tried to chase them down , but they lost him . Because of the spy ' s path , though , they were able to deduce that he must have gone into the mess hall . After realizing that all the people in the mess hall were clones , they were forced to conclude that the spy was one of their brothers . Cody then tried to contact Kenobi and Skywalker to no avail , as the droids were jamming transmissions . Deciding to continue investigating , they returned to the communications center , where , thanks to R2 - D2 , they discovered several external communications . They had taken place every few days , in a pattern irregular enough to avoid detection . The wavelengths were ultimately traced to a terminal in the barracks of Sargent Slick . Deducing that one of Slick ' s men was the spy , they decided to interrogate them in hopes of apprehending the individual . Revealed deception . Under the cover of night , Skywalker and Kenobi neared the Confederacy base — where the primary Separatist invasion army was landing and preparing to march on the city — on BARC speeder s through the streets of the ruined city . The two Jedi noticed an increasing number of battle droids spying them , but because the droids were not attempting to stop them or engage them , the pair realized that they were heading into a trap , but continued anyway . Upon arriving at the base , Skywalker and Kenobi were greeted by the hooded figure of Asajj Ventress . Upon sight of each other , all three adversaries ignited their lightsabers . Taunting her attackers with the knowledge of the spy , Ventress nimbly climbed to the top of the base ' s stairs . A lightsaber duel ensued when Skywalker slashed at Ventress , who drove him down to the bottom of the stairs . Kenobi joined the fight and engaged Ventress as well . Ventress fought Skywalker and Kenobi simultaneously with her dual lightsabers and used the Force to telekinetically throw a piece of crystal rubble at the duo . Kenobi sliced the projectile in half , and he and Skywalker gradually managed to drive Ventress back up the stairs . Ventress fled into another room , to where the Jedi pursued her . She summoned numerous books off their shelves and hurtled them at her pursuers ; Kenobi stopped them with the Force , and Skywalker ' s added telekinetic assistance forced the books back at Ventress . As the Dark Acolyte assumed a submissive seated position , the two Jedi approached her with lightsabers ignited . However , Ventress suddenly activated her own lightsabers into the floor and opened up a hole , causing Skywalker and Kenobi to fall into the room below . Ventress mocked the two before fleeing , and the two Jedi jumped back up into the room above and followed Ventress as she broke a window and hurtled out of it . While Ventress landed on the head of an octuptarra magna tri - droid attached to the side of the building , Skywalker and Kenobi walked onto the balcony and discovered the full scale of the Separatist invasion force : numerous C - 9979 landing craft were landing , bringing more and more battle droids to the surface , and many troops had already been deployed from their racks and were marching in formation on the ground far below . Despite the revelation of the enormous invasion force , Skywalker and Kenobi continued the duel and jumped onto the legs of the tri - droid , cutting off two of its legs and breaking its hold on the building . Ventress jumped off the droid ' s head and briefly engaged Skywalker upon one of the droid ' s remaining legs . As the droid plummeted to the ground , Skywalker Force - pushed Ventress away , and he and Kenobi each commandeered a Single Trooper Aerial Platform from the battle droids piloting them . Ventress reached the ground while the tri - droid crashed behind her . She then gave orders to General Loathsom through a tactical droid , ordering them to attack the city in order to keep the Jedi occupied while she carried out the next part of her master ' s plan - turning Jabba the Hutt against the Jedi and the Republic by kidnapping his son . She then left in her " Trident " - class assault ship , leaving Loathsom and the droid in command of the attack . Back at the Republic base , meanwhile , Rex and Cody , despite Slick ' s objections that it would demoralize his men , interrogated his squad ; Jester , Gus , Punch , Sketch and Chopper . All them had clean alibis except Chopper , who admitted that he was making a necklace out of battle droid fingers , against wartime protocol . Wanting to avoid suspicion , Slick put Chopper ' s authenticity in question . However , while telling Chopper that he did not have to say anything , he accidentally revealed that he knew the Jedi were gone . Chopper then lashed out , questioning why he had turned left , towards the command center , after returning , when everyone else went right , towards the mess hall and barracks . Cody then realized that he had said that the Jedi were gone , something Slick could not have known unless he was the spy . Found out , Slick punched Cody and dashed for the exit . Rex and Cody tracked him to the gunships and tanks , but found a primed thermal detonator instead of Slick . Rex and Cody took cover moments before numerous explosives went off and completely destroyed the landing pad , the All Terrain Tactical Enforcer s , and the weapon supply depot . Slick ran into the command center and hid in the vents above the room , and Cody and Rex pursued him there . The two officers engaged in a ploy to bait Slick out of the vents — while Cody left his DC - 15A blaster on the table and secretly removed the ammunition from his weapon , Rex appeared to leave for the south exit to restart the generators . Slick left his hiding spot , stole Cody ' s blaster , and pointed the weapon at Cody , at which point the commander revealed that it was empty . Rex re - entered the room , and the officers surrounded Slick . The sergeant stole Rex ' s blaster , and Cody lost his own blaster while disarming the Separatist agent . Cody knocked Slick down as the latter headed for the exit , and the two engaged in close combat before Rex pulled the clone traitor off Cody . Slick head - butted Rex and employed the " groin popper " maneuver to dislocate his leg . As Slick revealed the reasons behind his treason , Cody knocked him out and locked him in handcuffs . Once the Jedi returned to the base , the apprehended Slick accused them of " enslaving " the clones before he was taken to lock - up . Kenobi and Skywalker then sent Yularen ' s fleet back to Republic space for resupplying . Loathsom ' s assault . Battle at the capital . Skywalker ' s and Kenobi ' s forces were only able to save the cannons , but they set them up in anticipation of an assault . Sure enough , Loathsom launched an attack , consisting of B1 and B2 battle droids and three octuptarra magna tri - droids on the front lines , with AATs following behind in large numbers . In response , Kenobi and Cody led the main force of clone troopers — some mounted on All Terrain Recon Transport s — in a head - on charge against the droids in the main lane , while Rex , Skywalker , and a platoon of clone troopers to the top of a nearby tower . They surprised the octuptarra droids above , the clones using jetpacks to land on the street , and Skywalker landing on one of the droids . The team succeeded in taking out all three octuptarra droids and proceed to attack the advancing droid forces from behind . Seeing no other choices due to the Republic ' s heavy cannons , Loathsom was forced to pull back his forces in order to set up a deflector shield , and had an OOM command battle droid relay his orders to the front lines . The droid forces pulled back to regroup in the Separatist - controlled are of the city , though the battle " over " Christophsis continued to rage . With squadrons of starfighters waging dogfights across the space over the planet with the Separatists , Admiral Yularen quickly sent the young Padawan Ahsoka Tano to the surface aboard a Nu - class transport from the " Resolute " as a messenger from the Jedi High Council with important orders for the Jedi , since disruptions in the system ' s star had led to a communications blackout between Christophsis and the Jedi Temple . Tano landed in the city and was greeted by a surprised Skywalker and Kenobi , who had expected Republic reinforcements instead of her . Tano revealed to Skywalker that Jedi Grand Master Yoda had assigned her to be his Padawan , much to Skywalker ' s surprise and alarm . Back in City Plaza , Skywalker , Tano , and Kenobi managed to contact Yoda at the Jedi Temple through the " Resolute " — which was being battered by intense turbolaser fire from several " Munificent " - class frigates of the renewed Confederate blockade , itself numbering less than Admiral Trench ' s original fleet but still posing a significant threat — and , with all of their support ships already destroyed , requested reinforcements for the battle . Skywalker and Kenobi found that the Jedi Council had been unaware that the Republic forces had engaged the Separatists but managed to get the request for assistance across to Yoda . Before the conversation could continue , increasing enemy fire made the " Resolute " to drop the transmission . More Separatist ships arrived , and Yularen and the " Resolute " were forced to retreat from the system to avoid further damage . Without the Republic armada to provide support or transportation away from the planet , the Jedi were left trapped on Christophsis with limited supplies against the large droid army . Separatist counterattack . While the Republic watched the Separatist forces by using several towers throughout the city as lookout posts , Loathsom finished setting up a deflector shield generator and launched another attack . The Separatist force advanced behind its deflector shield , which negated the Republic ' s use of long - ranged artillery . The Separatist battle droids and AATs advanced through the city , followed by several lines of NR - N99 " Persuader " - class tanks . Meanwhile , Skywalker , Kenobi , Tano , and Rex meet at the command center and created an attack plan : Skywalker and Tano would infiltrate the Separatist - held area of the city and shut down the shield generator , while Kenobi and Rex buy them time by defending the base . With Kenobi and Rex rallying their men to defend the Republic ' s position , Skywalker and Tano proceeded with explosives to the advancing Separatist lines . The pair hide underneath a large box to pass the droid lines . Once the shield and the droid troops had passed over them , Skywalker and Tano made their way to the generator , but bumped into a droideka along the way . Forced to abandon their cover , Skywalker and Tano drew their lightsabers and manage to succeeded in cutting the enemy droid to pieces . They then reached the generator site , which , unknown to them , was being guarded by numerous LR - 57 combat droids . Meanwhile , Kenobi and Rex attempted to use the base ' s heavy cannons to defend their position in the city but were only able to verify that the weaponry was indeed useless against the droids ' deflector shield . Loathsom , meanwhile , ordered his troops to target the heavy cannons . As soon as the deflector shield swallowed them , Kenobi led a charge against the droids while Rex began to lure the enemy into the buildings , where his forces would have the advantage . As the Separatist forces overwhelmed their own , Rex had to order his men to fall back . He and Kenobi met at the command station where the general had Rex organize a defense of the cannons while Kenobi delayed the droids . Reluctantly , Rex agreed and fell back as Kenobi battled the droids by himself . However , he was soon surrounded by a squad of B2 battle droids , DSD1 dwarf spider droids , and Loathsom ' s personal AAT . Meanwhile , at the shield generator , Tano , against Skywalker ' s advice , ran towards the generator , accidentally activating buried LR - 57 combat droids . As the droids emerged , Skywalker attacked them in order to give Tano time to plant the charges on the generator . However , while avoiding one of the retail droids , Tano cut off it ' s ' head ' and Force pushed it away , accidentally activating even more droids . As Skywalker was being surrounded by the combat droids , Tano noticed a wall behind her Master with a hole in the middle . Tano carefully brought the wall down with the Force , managing to crush the droids around Skywalker without hurting him . Despite the fact that Tano had saved his life , Skywalker was infuriated with her recklessness and thought that he could have been killed . Meanwhile , in order to gain time for Skywalker and Tano to destroy the shield generator , Kenobi pretended to surrender to Loathsom . Kenobi was brought to a crystal table and patiently discussed the " terms of surrender " with Loathsom over a cup of tea , to the Confederate general ' s increasing impatience . Continuing to defend the heavy cannons with his men from their cover behind some fallen rubble at the end of the city ' s main street , Rex discovered that Kenobi had been captured but rallied his men to continue fighting . Loathsom finally realized that Kenobi was stalling and angrily overturned the table . Loathsom ordered two super battle droids to seize Kenobi and demanded that the Jedi General call off his troops immediately under the threat of being killed . At that moment , Skywalker and Tano detonated their charges and destroyed the shield generator , causing the shield to recede . Seeing the dissipating shield , Kenobi broke the droid ' s hold on him and grabbed Loathsom around the neck . As the battle droids took aim , Loathsom ordered his troops not to attack and surrendered to Kenobi . Back at the heavy cannons , Rex saw the shield dissipating and ordered the cannons to fire on the now - exposed battle droids . Just then , Yularen — accompanied by Master Yoda himself — came out of hyperspace with a reinvigorated fleet of " Venator " - class Star Destroyers and " Acclamator " - class transgalactic military assault ships . Ordering the cruisers to protect the transports , Yularen ' s forces engaged the blockade , managing to break through the Separatist defenses and forcing the enemy armada to retreat from the planet . Gunships were then deployed from the fleet to assist the heavy cannons in bombarding the remaining droid forces . One of the assault ships landed in the city , unloading clone reinforcements to further secure the Republic ' s victory on the planet . Aftermath . In defeating Loathsom , the Republic had managed to turn what would have been a Separatist victory into a gain for the Republic . Rex took an LAAT / i gunship to retrieve Skywalker and Tano from the generator site and brought them back to the Republic ' s base . Meeting with Skywalker , Tano , and Kenobi , Yoda told them that the son of crime lord Jabba the Hutt , Rotta the Huttlet , had been kidnapped by a group of renegades . Because rescuing Rotta was necessary to gain Jabba ' s favor , due to ongoing efforts for the Republic to gain access to hyperspace lanes in Hutt - controlled space , Skywalker and Tano ' s mission would be to rescue the captive Huttlet to gain Jabba ' s favor , while Kenobi would enter into negotiations with Jabba on his home planet of Tatooine . Based on clone intelligence reports , Skywalker , Tano , and Rex departed to the Wild Space planet of Teth to rescue Rotta from a monestary with the 501st detachment of Torrent Company . However , they were unaware that they were heading straight into a trap set by Count Dooku and his assassin Asajj Ventress , who were intent on claiming the hyperlanes for the Separatist Alliance and had orchestrated Rotta ' s capture with help from Jabba ' s own uncle , Ziro the Hutt , in order to manipulate the Jabba into turning against the Jedi . Republic High Command used the victory as an example of what Clones and Jedi , when together , could do . The battle had shown that a single Jedi and an armed squad of clone troopers could take out an entire column of battle droids . The Separatist realized this as well and began to research jedi - proof biological weapons . Examples of this project were the Defoliator and the Blue Shadow Virus . These two weapons would see use as soon as later in the first year of the war . Despite this boost to Republic , the CIS received a boost as well , in the form of Kenobi ' s false surrender , which Separatist - controlled media used as a clear sign of Republic duplicity . Nearly no more conditional surrenders were offered by either side throughout the remainder of the Clone Wars . The Republic was able to cover up all evidence of Slick ' s betrayal , and his motivations were kept a secret from all except Republic High Command in order to make sure that knowledge the clones weren ' t 100 % obedient stayed secret to stop any possible similar sentiments to Slick throughout the trooper ranks . While before the Jedi had viewed their leadership of organics to be more noble than the Separatists use of droids , they now realized they would have to deal with the factor of freewill . Admiral Trench somehow managed to escape the destruction of his flagship , though he was forced to undergo cybernetic reconstruction to replace several limbs and a part of his head . Loathsom was tried , presumably found guilty , and eventually wound up in the prison of the Republic Center for Military Operations . Behind the scenes .
