First Battle of Kamino The First Battle of Kamino , also known as the Defense of Kamino , the Assault on Kamino , or simply as the Battle of Kamino , took place two months after the First Battle of Geonosis . Background . Jedi Master Quinlan Vos , while working deep undercover under the name of Korto , an information dealer with a network of spies and thieves throughout the Republic and Confederacy , came into the possession of the Separatist ' s battle plans for Kamino . After Korto retrieved and relayed the information to the Jedi Council , his supposedly loyal assistant , Tookarti , reported to Count Dooku that his plans had been compromised . Dooku appointed Passel Argente , Magistrate of the Corporate Alliance , as the ranking officer for the battle , despite Argente ' s nonexistent military experience . Commander Merai , an expert in amphibious warfare , received the honor of leading the assault . After learning of the Confederacy ' s plans to strike at the nerve center of the Grand Army of the Republic , the cloning facilities on Kamino , the Jedi sent a defense fleet to protect the planet . The Jedi were divided into three groups , one on the ground protecting the facility from invading forces , and two squadrons of Jedi starfighters . Each squadron consisting of four Jedi starfighters , each piloted by a Jedi . One squadron , designated Blue Squadron , was led by Obi - Wan Kenobi , containing Anakin Skywalker , Tsui Choi , and Aayla Secura . The other squadron was Red Squadron , consisting of Jedi Master Kossex , and three other Jedi ; this squadron was to engage enemy landing craft and fighters , directly before they could get to land . Blue Squadron was in charge of picking off any surviving landing craft and fighters that made it past Red Squadron ' s attacks . While the Jedi on the ground , including Shaak Ti , would defend Tipoca City from invading Separatist forces . Oppo Rancisis and a Republic armada would wait out - system until the Separatist forces had fully launched their attack , then they would make a hyperspace jump and ambush the Separatist Fleet . The battle . The day of battle dawned , and Commander Merai sent down his landing ships accompanied by a squadrons of droid starfighters . A Jedi piloted star fighter squadron lead by General Kenobi engaged the droid forces as they entered the atmosphere . Despite initially holding the droid forces Kossex ' s ship was destroyed in a hail of droid fire while Obi - Wan ' s Jedi starfighter was shot down , with Skywalker sacrificing his in order to save his master . The droid forces then managed to land several troop transports in Tipoca City while the remaining Jedi star fighters pushed the droid fighters back . Jedi Master Shaak Ti and Kaminoan Prime Minister Lama Su inside a command center worked to protect the fetal and adolescent stage clones from Separatist sabotage , and activated the city ' s stasis - locked ARC troopers . Under the leadership of Shaak Ti and help from Obi - Wan and Anakin , the ARC troopers advanced through the enemy lines and prevented droid forces from further entering the city . Upon the arrival at the latest generation ' s labs , Alpha - 17 realized that the Separatist forces would overrun the labs . Based on his orders from Jango Fett , he couldn ' t allow the clones to fall into enemy hands , so he entered in a self - destruct code into a panel on the wall , which would result in a countdown to an explosion destroying the complex . However , due to Shaak Ti ' s complaints , his quick thinking allowed him to come up with an idea that would satisfy both her ideals , and his orders . He quickly told Shaak Ti , Anakin Skywalker , and Obi - Wan Kenobi to tear down the transparisteel bridge , and hold back Kamino ' s ocean from flooding the lab . Together the three Jedi successfully held back the water by forming a makeshift plug from the debris of the bridge they had just destroyed . This prevented the advancing Separatist forces from compromising and taking control of the labs . Alpha - 17 then quickly deactivated the self destruct sequence , saving both them and the next generation of Clones . Above the city in orbit , Commander Merai was forced to launch a desperate strike at the supposed location of the city ' s shield generator when the initial attack failed and Republic ships reinforced the Jedi star fighters . However , the Jedi proved too wily for the Mon Calamari tactician ; the data gathered by the Corporate Alliance was false — there was no shield generator — and Merai ' s efforts were in vain . Realizing his failure , he was forced to collide into the Jedi hyperspace rings lying in orbit to destroy them , in order to buy time for his forces as well as to prevent the fighters from following and attacking his fleet after they jumped from Kamino . He activated his self - destruct system , destroying his ship and the Hyperspace Rings . Upon Merai ' s death , the CIS retreated on orders from Passel Argente , thus ending the First Battle of Kamino . Aftermath . Though an apparent victory for the Galactic Republic , the battle actually engineered by Darth Sidious and his apprentice , Darth Tyranus , to disgrace the " upstarts " attempting to displace Dooku , to preserve the cloning facility for their future use after the conflict , to weaken the factions that might have been an impediment for them in the future , and most importantly for Jedi to die . As a result of the battle , Ko Sai told Yoda that the clone army had been funded by a man named Tyranus . Ko Sai also deserted after the battle and went into hiding .
