First Battle of Geonosis The First Battle of Geonosis , known most commonly as simply the Battle of Geonosis , was the first battle between the Confederacy of Independent Systems and the Galactic Republic in the conflict that would become known as the Clone Wars . It would be the first major combat of the Grand Army of the Republic , as well as the first major battle the Jedi would fight in years . Prelude . In 22 BBY , the Galactic Republic was in the midst of a crisis . Thousands of star systems and conglomerates including the Trade Federation , InterGalactic Banking Clan , Techno Union , Commerce Guild and the Corporate Alliance , had seceded and joined the Confederacy of Independent Systems under the guidance of former - Jedi Count Dooku as terrorist strikes hit the capital planet Coruscant . The Republic Senate planned to meet that year to discuss the Military Creation Act . Three months before the vote , angry showdowns occurred between planets ' inhabitants and among the two opposing governments while the Refugee Relief Movement tried to help where possible . The day of the vote , Senator Padmé Amidala of Naboo arrived on Coruscant to vote against the Act , but faced an assassination attempt . She was then assigned Jedi protectors — Obi - Wan Kenobi and his youthful Padawan , Anakin Skywalker . Kenobi followed the trail of the toxic dart which ended the life of the assassin while Skywalker escorted the Senator back to Naboo . Kenobi followed the tip from his friend Dexter Jettster to the planet Kamino , which had been erased from the Jedi Archives by forces unknown . There he discovered that ten years earlier , Jedi Master Sifo - Dyas had placed an order for a clone trooper army . During the tour , he met the bounty hunter Jango Fett . Kenobi reported back to the Jedi Council and decided to pursue Fett , suspecting that he was involved in the assassination attempt . They battled on a landing platform , and Kenobi was able to plant a homing beacon on Fett ' s ship . On his way to Geonosis , Dooku encoded a message to General Sev ' rance Tann telling her he foresaw a great battle was about to happen . He also ordered her to prepare for his swift departure . Kenobi pursued Fett to Geonosis . His ship barely avoided a homing torpedo , and he landed on the surface . He snuck into a facility and watched a meeting of Separatist leadership , where it was revealed that Viceroy Nute Gunray of the Trade Federation was behind Amidala ' s assassination attempt . Kenobi reported back to the Jedi Council but was captured by destroyer droids . His signal was rerouted through Amidala ' s ship on Tatooine , as she and Skywalker had traveled there in a failed attempt to rescue his mother . Meanwhile , Dooku met with the captive Kenobi to try to turn him to his side , even revealing that the events on Naboo years prior had in fact been orchestrated by a Sith lord named Darth Sidious , and also strongly insinuated that Sidious was one of the high ranking officials of the Republic ' s government . Kenobi refused , and Dooku suggested it would be difficult for him to secure his release . Skywalker and Amidala traveled to Geonosis to rescue Kenobi but were captured in the Geonosis droid foundries . The two were sentenced to death in the Petranaki arena along with Kenobi . When Kenobi enquired them as to why they were present , Skywalker explained Amidala ' s idea to rescue him , with Kenobi sarcastically congratulating them for the failed objective . They narrowly escaped their executions , which involved an acklay , a nexu , and a reek . In response to Kenobi ' s report about the Separatists ' conspiracy , the Galactic Senate , at the suggestion of Representative Jar Jar Binks , granted Supreme Chancellor Palpatine " emergency powers " to deal with the crisis . Jedi Grand Master Yoda brought the secret clone trooper army into use , and sent them to Geonosis right behind a Jedi strike force . The rapid nature of the deployment off Kamino left " Cuy ' val Dar " sergeants such as Kal Skirata reeling at waking up to discover the commando squads they had trained gone . The battle . Penetrating the defenses . A group of 212 Jedi , led by Jedi Masters Mace Windu , Coleman Trebor , Eeth Koth , Kit Fisto , Plo Koon , Shaak Ti , Even Piell , Luminara Unduli and Ki - Adi - Mundi were sent to Geonosis by the Jedi High Council to rescue Obi - Wan Kenobi and investigate reports that Separatists were constructing an army on Geonosis . Upon entering the system , the fleet of Jedi starfighters were fired upon by Anti - orbital cannon s , taking several casualties . Mace Windu and Luminara Unduli slipped past the firing range of the cannons and piloted TX - 130S fighter tanks , and employed communications jamming to stop any CIS forces from calling for reinforcements . They set off to disable the orbital cannons . The droid defenses , consisting of GATs , Hailfire droids , and STAPs , attempted to hold them off , but were destroyed by the Jedi . The power nodes were destroyed , causing the cannons to explode . The last cannon , however , was housed in a Geonosian base . Windu set out on foot to disable the cannon . He penetrated the droid defenses and destroyed the last power nodes with his lightsaber . With the orbital defenses disabled , a landing zone had to be made . The Jedi strike team landed in a captured Confederate outpost and moved toward the arena in a convoy of RTTs . Windu and Unduli cleared the way in their tanks . They reached the perimeter of the arena , where they destroyed tunnel catacombs deploying battle droids . The Jedi deployed into the arena quietly . Also around this time , the " Acclamator " - class assault ship " Aken " was traveling to Geonosis through its asteroid belt . " Aken " was escorted by Jedi starfighters lead by Adi Gallia , who had traveled from Nod Kartha , and Siri Tachi . After they were spotted by droid starfighters , the Jedi had to defend the " Aken " from two C - 9979 landing craft and two Trade Federation Missile Frigates that appeared behind them along with Geonosian starfighters from the surface . The Separatist forces pushed the Republic group forward until the " Aken " reached the edge of the asteroid ring . There , a blockade of Missile Frigates arrived to trap them . Gallia led the starfighters and destroyed a pair of the frigates in their line . This allowed the " Aken " to escape and eventually reach the surface of Geonosis . Eventually , the rest of the " Acclamator " - class Assault ships penetrated the atmosphere , and proceeded to make pre - emptive strikes against the Geonosian beak - wing facilities , which resulted in the few fighters remaining unable to make headway against the Republic ' s orbital blockade . Republic Strategic Command , including the Zilkin Meebur Gascon , was involved in planning the battle and analyzing maps to direct Republic forces . Gaba - 18 airspeeder s provided reconnaissance . V - 19 Torrent starfighter prototypes also fought in the battle . Arena battle . The three captives , Skywalker , Amidala and Kenobi managed to avoid the beasts that had been set upon them long enough for Master Windu ' s 212 - Jedi rescue mission team to arrive . However , Count Dooku revealed the Separatist ' s new secret battle droid army , and a heated battle took place . At one point in the battle , the Padawan Tu ' ala , taking after her master , sacrificed herself to save Anakin Skywalker from a Geonosian soldier . Though outnumbered , the Jedi fought to the end . As the Jedi appeared throughout the arena , many Geonosians fled . It was during the heated battle that followed that bounty hunter Jango Fett attempted to fight and kill the legendary Korun Jedi Master , Mace Windu . However , during the fight , the reek nearly trampled Fett and damaged his jet pack . After killing the reek , Fett was charged by Mace Windu ; at the last second the Mandalorian attempted to activate his jetpack , but failed . Mace Windu quickly beheaded the infamous bounty hunter . His battered helmet was soon found by his " son " Boba Fett . However , Dooku ' s forces held the upper hand . C - 3PO had accidentally lost his head in a droid factory , and his head was attached to a battle droid ' s body , while his own body walked onto the assembly line and had a battle droid ' s head attached in turn . Both incarnations of C - 3PO were defeated in the arena and were re - attached by R2 - D2 . Eventually , Dooku signaled for a cessation of the fight . He offered the chance to surrender , but Windu refused , saying the Jedi would not become hostages . Dooku then remorsefully signaled the surrounding droids to execute the Jedi . Meanwhile , huge Republic assault ships penetrated the upper atmosphere and dropped a fleet of gunships , carrying thousands of clone troopers and dozens of AT - TEs as well as Jedi General Yoda , to the surface . By the time the fleet reached the arena , the Jedi had already suffered heavy casualties ; all but 30 had been killed . Yoda ordered the clones to form a perimeter around the survivors as they evacuated . As they left , the empty stadium was littered with droid parts as the opening battle of the Clone Wars began . A Jedi joined the strike team , cutting down numerous battle droids . As the battle spread past the arena , the Jedi continued to fight . Desert battle . Around the time of the arena battle , a group of clone troopers lead by Jedi Master Adi Gallia and Jedi Knight Siri Tachi attacked a power plant that fueled the droid foundries in the surrounding area . After having escorted the " Aken " to the surface of Geonosis , Master Gallia and Siri Tachi led several LAAT / i gunships at their command to deploy troopers near the power plant . The two Jedi defended the clones on the ground and in the air from Separatist forces which included battle droids , Armored Assault Tanks , and droid starfighters . Along the way , Gallia had the gunships destroy a nearby Trade Federation Core Ship . Clone troopers eventually reached the power plant and set up explosives inside it . After the plant was detonated by the clones , Adi Gallia and Siri Tachi took to space to prevent Separatist transports from escaping . After the rescue of the Jedi , the droid and clone armies engaged one another in a complex series of engagements on a number of different fronts . The Republic had planned the attack as a sudden , overwhelming assault that would catch the Separatists off guard and prevent them from gaining further influence . Their army landed in twelve " Acclamator " - class assault ships , off - loading infantry , armored vehicles , artillery , and air support . The Separatist army consisted of droid infantry of varying strength and larger droid - controlled vehicles . The Battle of Geonosis was primarily a ground campaign . However , the Republic ' s crucial use of aerial bombardment of the Separatists ' fighter craft allowed the Republic ' s gunships to have air superiority throughout much of the battle , giving the clone forces a crucial advantage . And although the clone troopers were vastly outnumbered by droids , the droids were heavily exposed to attacks from the air by Republic gunships . The Republic ' s armored AT - TE walkers were strong against the lightly armored spider droids employed by the Separatists , but were vulnerable to the missiles on the Hailfire droids and the intense laser flak projected into the air . The Republic gunships were instrumental in clearing away the Hailfire droids and allowing the AT - TEs to establish superiority on the battlefield , although the Hailfires were able to shoot down a number of LAATs , and a few were destroyed by lucky shots from laser emplacements . Clone trooper CT - 1226 ' s regiment was deployed near the arena . A wave of droids headed toward the force . One of the Republic walkers launched a projectile which created a crater , and CT - 1226 fell into it . A Hailfire droid passed over his head . A B2 - HA series super battle droid swatted aside B1 battle droids to target one of the walkers . CT - 1226 was able to target the B2 ' s heat exchangers , and a missile the droid launched hit a Hailfire instead . CT - 1226 disabled the B2 with an electromagnetic pulse grenade and destroyed the droid with his blaster . The clone was then helped inside the walker as it plowed through the hole in the droid ' s defensive formation CT - 1226 had formed . Separatist General Sev ' rance Tann was ordered to clear the way for Count Dooku . Along with a force of B2 super battle droids , she proceeded along a canyon where Confederacy forces engaged Republic forces . Tann took control of surviving units , including Mortar Super Battle Droid s , Repeater super battle droid s , heavy dwarf spider droid s to battle Clone Scout Walker s and Clone Personal Walker s , and OG - 9 spider droids to duel AT - TEs . At least one Blurrg trooper fought in those skirmishes . A trooper kept Tann updated with Count Dooku ' s status . Near the end of the canyon , Tann dueled and defeated three Jedi Knights . When Dooku arrived at the end of the canyon , he congratulated her for her efforts . Republic reconnaissance troopers mounted their speeder bikes and raced across the battlefield , gathering vital information about enemy activity . Elsewhere , Geonosian - trained acklays and nexus devoured unfortunate clone troopers . A group of the airborne infantry , including Battalion Commander CRC - 09 / 571 , led the frontal assault on the Separatist Core Ships . Jedi Master Mace Windu , who was fighting on the ground , made his way to a LAAT / i and used it to destroy several " Hardcell " - class interstellar transports before landing and defending in a TX - 130 " Saber " - class fighter tank SPHA guns bringing down Core Ships . In this way , another three Core Ships were taken down , before Windu was informed that contact with Master Yoda had been lost . Windu raced off to find the Grand Master but was intercepted by a trio of Dooku ' s Sith Acolyte s piloting Enforcer hovertanks . Windu was able to defeat the trio . Having beaten the droid army into retreat , Yoda noted that much of the Confederate Navy was still grounded receiving shipments of droids when the Republic attacked . Lightly armored and vulnerable Techno Union starships attempted to withdraw immediately , but many were destroyed in the first wave of attacks from the Republic gunships . The Jedi Master now ordered the army ' s artillery to attempt to take down as many of the heavily armored Trade Federation Core Ships as possible , as they each held millions of deadly battle droids , and managed to bring down at least one . In space , the Republic fleet fought to intercept and destroy the Separatist ships that carried scores of combat droids . Despite taking control of the surface of the planet , the Republic was unable to capture the Separatist leadership and stop the war before it began , and most of the Confederacy ' s battle droids and heavy equipment escaped aboard Core Ships . Meanwhile , Jedi Master Echuu Shen - Jon and a team of other Jedi , including Plo Koon , destroyed several Core Ships and Techno Union vessels . They received reinforcements in the form of 10 GAR Energy Pummel s carried aboard AA - 9 freighters while a nearby Republic Starship and Gunship Bomber s engaged targets of opportunity . Corporate Alliance Artillery Regular s were among the Separatist forces . The Jedi team then set off to pursue Count Dooku . However , they were delayed by Sev ' rance Tann , who killed Stam Reath , Echuu ' s apprentice , angering Shen - Jon . Tann then escaped . In the midst of battle , the Republic ' s Hawkbat Battalion was ordered to march directly into the line of fire of a column of spider droids . The battalion was almost completely annihilated , but Captain CT - 65 / 91 - 6210 , leader of K Company , stayed behind in a shallow crater to tend to two critically injured troopers at great personal risk . Surrounded by spider droids , he defended their position for three hours until the casevac team arrived . His heroic acts had not been in vain , as the two men under his command were rescued . Elsewhere , ARC trooper CT - 96 / 298 , previously having studied power cell recharge cycles , recognized when a Hailfire droid was about to enter a reflux pattern . The whine of the droid ' s capacitor was barely audible , but CT - 96 / 298 leapt from cover and eliminated the Hailfire before it could explode , thus saving the lives of five of his cohorts . Deep within the Geonosian catacombs , the Separatist Kaleesh / cyborg General Grievous had his first combat deployment during the battle . He killed Master Ur - Sema Du and a battalion of clone troopers with an electrostaff , claiming the Jedi ' s lightsaber as part of what would soon be his gruesome " collection . " Later , above a crevasse , the Republic Commando squad Theta Squad rappelled in and placed charges on a Geonosian door , while Delta Squad held off OG - 9 homing spider droids nearby . After the door was blown , Theta and Delta entered the Geonosian caverns and split up . Heading for a droid foundry , Theta squad leader RC - 1133 ordered RC - 1136 to stay behind and hold a position while the rest moved forward . 1136 , or Darman , lost contact with his squad and pulled out . He was the only survivor of Theta . Delta Squad managed to kill Geonosian Separatist General Sun Fac as he attempted to flee the planet in his personal Geonosian fighter . They also spotted General Grievous ' s " Soulless One " . The acquisition of the codes allowed the Republic artillery and fleet to take down the rest of the CIS fleet . Along the way , Delta Squad also eliminated significant numbers of droids , Geonosian warriors , and an anti - aircraft turret . A LAAT / i gunship deployed the four members of Delta Squad into a canyon relatively close the Core Ship access way . They proceeded into the canyon , and fought through a series of ambushes . They finally reached the entrance to the Core Ship , but they were unable to penetrate the shield , so their Clone advisor , CC - 01 / 425 , ordered them to blast through a rock wall to reach a nearby exit . RC - 1138 led his three commandos towards the second door , and the defending droids were destroyed in short order . Suddenly , however , an A - DSD advanced dwarf spider droid came through a different doorway , and began firing its cannons at the stranded squad . After several intense minutes , the droid was blown up , and a gunship blasted the shield protecting the Core Ship ' s entryway , allowing access for Delta Squad . The squad split up , tasked with sabotaging various crucial systems . RC - 1138 stormed through the B2 battle droid storage racks , rapidly finishing off any of them that were activated . RC - 1138 found Sev in a corridor just before three destroyer droids rolled by , but they easily destroyed them using EC detonators , proceeding to save Scorch and Fixer , who were under heavy fire . Now together Delta Squad encountered a B1 battle droid dispenser , then several Geonosian elite s and a second Advanced dwarf spider droid . Entering a lift , the squad prepared for their ultimate objective , the theft of the Core Ship launch codes , which were housed on the bridge . At that moment , a battle droid announced over a loudspeaker that all primary systems would overload in five minutes . Delta Squad charged through multiple corridors , meeting dozens of droids on the way , and finally entered the bridge with only about one and a half minutes to spare . They brought down three auto - turrets and a squad of B1 battle droids , and Fixer began extracting the codes from a console as droidekas and B2s began swarming onto the bridge . After a minute , Delta Squad , gravely injured and being constantly hit by laser bolts , retreated through a corridor to a waiting LAAT / i Gunship just as the Core Ship began to explode . Delta squad was one of only a handful of Republic Commando squads not to lose any members during the Battle of Geonosis . 501st Mission . During the battle , a portion of the 501st Legion engaged in combat . A clone trooper was assigned to secure Checkpoint Alpha . He encountered three B2 super battle droid scouts , but managed to destroy them before they called in reinforcements . Blowing a Hailfire droid to pieces with his thermal detonators , he then secured the wreckage of a nearby " Hardcell " - class interstellar transport . The events soon became a full scale battle between the Geonosians , droids , and clones . A clone engineer was deployed to repair the Power droids and FX - series medical assistant droids , ensuring ammunition and medical supplies would aid the battle . During the course of the engagement , two Spider Droids arrived on the battlefield . The clone engineer was then ordered to the recently - deployed AT - TE . The Republic force soon destroyed the droids to prevent the balance of power from swinging . A Geonosian soldier was shot and killed , which resulted in him dropping a Sith Holocron on top of the wrecked " Hardcell " . A clone jet trooper was called in , and managed to get the Holocron to Checkpoint Alpha . The troopers then used the AT - TE to mount an assault on a nearby hill fortress , soon securing it . A clone sniper was deployed , and picked off Geonosians and droids alike . A clone heavy trooper came into play , using his rocket launcher to destroy a Spider droid . General Windu arrived shortly after , and led an assault that secured the Northern CIS bunker against droids including Assault battle droid s , engineer battle droid s . and IG - 100 MagnaGuards . Spire Mission . Master Yoda then sent a group of clone troopers , an AT - TE , and a couple of LAAT / i gunships into battle . Their mission was to secure the Spire council chamber , and wipe out the remaining droids in the area . They first destroyed the Techno Union Transport ships , denying the droids escape . The clone troopers then wiped out the remaining droids , and successfully captured the spire . The droid defenses included battle droid assassin s , B2 battle droids , and destroyer droids . Space battle . Following an initial raid on a Geonosian power plant , Adi Gallia and Siri Tachi , flew into orbit in their Delta - 7 starfighters , intending to intercept escaping droid transports . Navigating through the asteroid ring , the Jedi received a hyperspace transmission from the pirate Nym , warning that Captain Cavik Toth of Sabaoth Squadron was en route to Geonosis with his Hex fleet . With the power of the biological weapon Trihexalon , Toth intended to level the battlefield on Geonosis , under the orders of Count Dooku . Galia and Tachi led the fight against Toth ' s 8 Hex Deployer s and 12 Bombers alongside Zeta Squadron , a squadron of Jedi pilots , including A ' Sharad Hett , Bant Eerin , and An ' ya Kuro . The Hex threat was summarily defeated under Jedi firepower , though the pilots were soon outmatched with the arrival of two Sabaoth destroyer s and complements of Sabaoth starfighter s and Defenders . Fortunately , Loyalist aid arrived in the form of Nym and the Lok Revenants with three G - 400 starfighters and Nym ' s " Havoc " soon joined by three Mere cruiser s capable of taking down Toth ' s capital ships . Nym and his forces dealt with the capital ship turret s on the destroyer s while the Jedi attacked the waves of fighters . After one warship was destroyed , a third Destroyer emerged from hyperspace — Toth ' s flagship . The Mere cruisers , led by Antilles on the " Tritus " , directed their fire on the second vessel while all starfighter forces then began to target the flagship ' s capital turrets before they could cripple the Mere cruisers . Developments on Geonosis forced Master Windu to call back Zeta Squadron leaving Gallia and Tachi with only the Revenants for support . Nym sustained critical damage to his craft during the fight , and was forced to leave the battlefield . Nevertheless , the Revenants penetrated the flagship ' s deflector shields , and the Destroyer ' s main systems went critical . Toth himself fled his flagship in a personal starfighter , and engaged Adi Gallia in single combat . Toth ' s weaponry could not overcome the Jedi ' s mastery of the Force , and his fighter was destroyed moments before his flagship exploded . Confrontation with Darth Tyranus . In the confusion of the battle , the Separatist leader Dooku , also known as Darth Tyranus , tried to flee to a hangar where his starship was docked . A Republic gunship carrying Obi - Wan Kenobi , Anakin Skywalker , Padmé Amidala , and clone troopers pursued him . Dooku ' s wing guard of fighters piloted by Geonosians opened fire on the gunship ; the resulting attack on the gunship led to Amidala and a clone trooper falling to the desert below . The gunship continued to give chase , deploying Kenobi and Skywalker into the Count ' s hangar shortly before being destroyed by laser fire . Trailing Dooku and the Republic gunship was General Mace Windu in a fighter tank , who was intercepted by three of Dooku ' s Dark Acolyte s in front of the hangar . They engaged Windu in combat , and all three were killed by the Jedi Master ' s TX - 130S fighter tank , but not soon enough to allow the Korun master to involve himself in the fight . Kenobi vs . Tyranus . Upon arriving at Dooku ' s hangar , Kenobi and Skywalker challenged the Count . As Kenobi began to strategize , Skywalker , his anger getting the best of him , charged at Dooku . Dooku released a barrage of Force lightning and blasted Skywalker aside before turning to Kenobi . Kenobi began to circle Dooku as the Count attempted to blast Kenobi with another bolt of Force lightning , demanding the Jedi Knight ' s surrender . Kenobi grounded the blast on his lightsaber and calmly stated that he would not withdraw . Drawing his lightsaber and angling the blade into a guard position , Dooku awaited Kenobi . Kenobi promptly charged at Dooku and attacked , but Dooku quickly deflected Kenobi ' s initial attack and his subsequent jab . After a quick flurry of bladework , Kenobi slashed at Dooku ' s legs . Dooku overleapt the attack and flourished his blade to drive Kenobi back as he landed . As Kenobi fell back , Dooku calmly taunted him , telling him that he had expected a better performance from someone who was held in such high esteem by Yoda . Kenobi attacked again , attempting to regain the offensive , but was forced into retreat by Dooku ' s elegant Form II bladework . Dooku quickly seized the offensive , the precision bladework of his Makashi style wearing away at Kenobi ' s Form III defense . Despite the energy efficiency of Kenobi ' s defense , Dooku ' s precision was so great that most of Kenobi ' s defensive slashes missed Dooku ' s blade entirely , forcing him to awkwardly scramble to fend off Dooku ' s attacks and quickly tiring him . Eventually Kenobi , straining to keep up , was pulled into a bladelock . Dooku , a wide grin on his face , pushed Kenobi ' s blade aside , and suddenly jabbed at Kenobi ' s arm , cutting it across the side . As Kenobi fell back in pain , the Count stayed on him , slashing the Jedi across the leg and bringing him down . Despite his wisely shown restraint against Dooku , Kenobi , fatigued by the battle , wielding an unfamiliar lightsaber , and outmatched by Dooku ' s skills , was defeated . As Dooku raised his lightsaber to kill Kenobi , Skywalker recovered from the blast of Force lightning and saw Kenobi ' s predicament . Leaping across the hangar from the corner in which he lay , Skywalker reached the two in time to block the Count ' s blow . As Dooku turned to regard Skywalker , Kenobi used the Force to retrieve his fallen lightsaber and tossed it to Skywalker . Skywalker vs . Tyranus . Skywalker , taking up the second blade , began to unleash of flurry of broad Form IV attacks , briefly taking the Count off his guard . Dooku was able to recover his guard and drive Anakin back . Skywalker was forced to revert to his standard Form V practices when Dooku masterfully disarmed him , flicking his second blade out of Skywalker ' s hand and destroying the hilt in mid air . Warding off Dooku with two rapid strikes , Skywalker quickly retreated , regaining his composure . Slashing a power cable connected to Dooku ' s ship as he raised his blade into a high guard , Skywalker caused a short circuit that briefly caused the hangar lights to flicker . As the chamber dimmed , the two advanced on each other . As they stared at one another , blades at the ready , Skywalker attacked . The two engaged in a flurry of swordplay , seemingly equally matched . Briefly breaking off , Dooku quickly reassessed Anakin ' s strength before quickly attacking , and the duel resumed . Despite holding his own against Dooku for much of the duel , Skywalker was finally brought down when Dooku twirled and slashed off his arm with a sudden undercut . As Anakin cried out in pain , Dooku blasted the Jedi aside with a Force push . Yoda vs . Tyranus . As Dooku briefly caught his breath , he noticed the sound of footsteps and the clack of a cane , as well as the characteristic panting . Turning to the hangar entrance , Dooku and the newly - arrived Yoda regarded one another . Dooku attempted to kill Yoda by telekinetically ripping wall fixtures out of the hangar sides and hurling them at Yoda . When the ancient Jedi blocked , Dooku countered by ripping chunks of stone out of the hangar ceiling , a dangerous proposition as the hangar was carved out of a cavern and doing so could cause a cave - in . Yoda caught the chunks and threw them aside , turning to Dooku and acknowledging his power , but noting that he sensed the dark side of the Force in Dooku . Dooku , affirming his apparent superior power , unleashed a barrage of Force lightning at Yoda . The Jedi effortlessly caught the lightning and deflected it back at Dooku , who again deflected it into a nearby wall . Dooku proceeded to unleash a second blast against Yoda , but as a show of his mastery , Yoda absorbed the bolt completely , with no need for deflection , showing Dooku the clear futility of this assault . Dooku brandished his lightsaber , stating that this contest would not be decided by their mastery of the Force , but rather by their skill with a lightsaber . As Yoda drew his own weapon , Dooku leapt into action , unleashing his full Form II mastery against Yoda . However , Yoda ' s own mastery of Form IV allowed him to hold off Dooku ' s relentless attacks , and seize the offensive . Realizing both that he would not be able to defeat Yoda and that Republic reinforcements would soon arrive , Dooku distracted Yoda by using the Force to topple one of the hangar ' s power columns onto Kenobi and Skywalker . As Yoda broke off the duel to telekinetically catch the power column , Dooku was able to quickly board his ship and escape . Aftermath . The explosion of Toth ' s flagship was seen from the surface . Master Windu contacted Master Gallia for a status update . Gallia confirmed her mission was successful , and Windu informed her that the battle was over , although Dooku escaped and Skywalker had been wounded . The two later had a private meeting in the High Council Chamber . By the end of the battle , only Republic soldiers remained . However , the victory had not come easy . When the Republic assault ship " Implacable " was extracted from Geonosis to Ord Mantell , med triage on board estimated 12 , 000 seriously injured men and 8 , 000 walking wounded . Approximately 72 , 000 clones were deemed combat - fit . Thousands of clone troopers had died in the fighting , and most of the Confederacy ' s army had been safely evacuated aboard Core Ships during the battle . Geonosian Archduke Poggle the Lesser had fled along with the rest of the Separatist Council , and his warriors had retreated into the catacombs , where they resisted the Republic ' s every effort to dislodge them . Count Dooku traveled to Coruscant to meet with his master , who was settled in an abandoned executive building in The Works , not far from the Senate District and the Jedi Temple . Pleased by the news of war he received from Dooku , Darth Sidious ordered the former Jedi , now the Sith Lord Darth Tyranus , to retreat to Raxus Prime to prepare a second battlefront against the Republic . Meanwhile , the Grand Army of the Republic was mobilized throughout the galaxy as the Clone Wars began . The main reason for the Separatist ' s defeat was that they were caught completely by surprise , working against their numerical superiority . Another reason they lost is that despite the fact Sev ' rance Tann and General Grievous , arguably the Droid Army ' s most brilliant commanders , were present , they were not given command of the army , and were instead placed in support positions . Grievous remained unknown to the Republic , for he killed off any of the Jedi or clones he encountered , while Sev ' rance Tann escaped Geonosis after killing Shen - Jon ' s Padawan , Stam Reath . Cuy ' val Dar sergeant Kal Skirata lost nine commandos that he trained in the battle , namely the casualties from Theta Squad , Prudii Squad , and Teroch Squad . He , Walon Vau , RC - 1309 , and RC - 8015 would later reflect that this had been due to the Jedi ' s ill - advised usage of the commandos as infantry rather than special forces . While back at the Jedi Temple on Coruscant , Masters Kenobi and Windu both expressed their mutual belief that the battle would not have been won without the clones , but Master Yoda retorted at the irony of Obi - Wan ' s use of the word " victory . " The battle was but the first of many in what became known as the Clone Wars . They also decided to investigate the Sith Lord that Dooku had mentioned to Obi - Wan Kenobi during the latter ' s imprisonment , Darth Sidious , in case Dooku was truthful about this revelation . It would not be until three years later , nearing the end of the Clone Wars , that they would eventually identify Sidious as being none other than the Supreme Chancellor , Palpatine . Skywalker , meanwhile , escorted Senator Amidala back to Naboo , where they were wed in a secret ceremony . After the battle , a collection of reports known as the Geonosian Debriefings was compiled , and for his role in the battle , CT - 1226 was given a medal at the insistence of the Republic generals . Jango Fett ' s son Boba buried his father and then took his ship to the moons of Bogden , where he engaged in a firefight . The pirate Nym was later offered the post of commander of the Karthakk system , although he declined . Gallia then volunteered to be his personal " Jedi advisor . " In the months following the battle Mace Windu would regret his decision not to strike down Count Dooku when he had the chance , and killing Jango Fett without a second thought . Depa Billaba would later state to Windu on Haruun Kal that by simply bombing the arena on Geonosis , the Republic could have prevented a war that destroyed billions of lives at the expense of only a few hundred Jedi . As the Separatists and Republic built up their forces , they engaged in harassment tactics . Shortly afterward , the opposing governments fought the Decimator campaign and the Dark Reaper Crisis . Months later , the Republic occupation force was defeated , necessitating another planet - wide invasion . Around two years after the battle , the Republic built on Coruscant a memorial listing the names of every clone trooper that died during this first battle . Three years after the battle , when Skywalker and Kenobi confronted Dooku for what was ultimately the final time aboard the " Invisible Hand " above Coruscant , Kenobi told Skywalker that they are to fight him together this time around , referring to Skywalker ' s earlier brash attempt at attacking Dooku head - on that got him blasted with Force Lightning , with Skywalker admitting he was going to suggest the exact same thing . Behind the scenes . The First Battle of Geonosis continued the " Star Wars " saga ' s tradition of huge battles in the 2002 film . A scene where Plo Koon and Ki - Adi - Mundi raid a " Lucrehulk " - class Droid Control Ship was originally going to be included , but did not appear in the final cut .
