Battle of Zaadja The Battle of Zaadja was a confrontation during the Clone Wars which occurred approximately eighteen months after the First Battle of Geonosis . The result of a massive expansion of the Confederacy military , Zaadja became a large battle droid manufacturing facility under the control of the Geonosians . The battle witnessed the landing of the Third Systems Army under the command of High Jedi General Obi - Wan Kenobi and Anakin Skywalker ; General Kenobi ' s forces were to act as a diversion for the actual Jedi mission to succeed . Attached to the Republic forces was the Jedi Knight Tohno , who was charged with the primary mission of infiltrating the Separatist droid factory in an effort to plant explosives , which would destroy it from within . The outcome of the battle saw the Republic forces emerge victorious , but also witnessed the sacrifice and death of Jedi Tohno . Prelude . With the progression of the Clone Wars , the Separatist forces began growing as new worlds and allies began joining the war against the Republic . Using numerous worlds as manufacturing bases , the Separatist Droid Army began adding to its ranks a seemingly endless supply of droids . One of the many planets chosen to provide the Separatists with material needed for the war was the world of Zaadja . Realizing that they needed a way to slow down the Separatist ' s droid production , the Republic began formulating a variety of missions aimed at neutralizing as many of these factory - worlds as possible . When word of the facility on Zaadja reached the Republic , a special mission was formulated by the Jedi and placed under the direction of Obi - Wan Kenobi and Tohno . Along with Kenobi ' s Padawan Anakin Skywalker and the Third Systems Army , Kenobi and Tohno traveled to Zaadja to carry out their mission . The battle . In a plan developed by Obi - Wan Kenobi and Tohno , and approved by Jedi Masters Mace Windu and Oppo Rancisis , the Republic mission called for a two - pronged course of action : Acting as a diversion , Kenobi and Skywalker would lead the Third Systems Army onto the field of battle to draw the Separatist forces away from the droid factory on Zaadja ; concurrently , Tohno was tasked to infiltrate the droid factory and destroy it using military - grade explosives . Due to her unique training in architecture and engineering , Tohno was chosen for this specific mission because her skills would allowed her to determine how best to destroy the manufacturing plant . If the diversion and mission was successful , then Tohno would be able to extract herself back to Republic lines where she would rejoin Kenobi and the Third Systems Army . Although Tohno was initially able to infiltrate the factory unnoticed , she was soon discovered by a large number of Geonosian soldiers tasked with preventing such an incursion . Using the Force to conceal her movements , she managed to get past the majority of enemies , but was confronted by a Geonosian sentry before she was able to reach the heart of the factory . Fighting her way through a large number of the enemy , Tohno was able to plant the majority of her explosives before more Geonosians caught up with her . Meanwhile , a restless Anakin Skywalker , who had been struggling with the need for so many Jedi to sacrifice themselves thus far in the war , sensed that Tohno ' s survival was in jeopardy . Using his radio to communicate with her , Skywalker reassured her that he was inbound to her position with a gunship to lend her his aid . Disregarding her own personal safety , Tohno ordered the young Padawan to remain with Master Kenobi and his clone soldiers . Though Skywalker continued to argue with her , Tohno was able to convince him that if he came after her , it would cause needless casualties among the troopers of the Third System Army . Having realized that she would not survive her mission , Tohno wanted to complete it with as little loss of life as possible . Reluctantly turning back to the Republic lines , Skywalker came to understand that Tohno ' s personal sacrifice was what was needed for the mission ' s success . While she had been reasoning with Skywalker , Tohno had managed to make her way to the center of the factory , which contained the power core for the whole facility — it was also where she was confronted by more Geonosian soldiers . Though she was able to mount an impressive defense , Tohno was eventually overrun by the enemy soldiers — nevertheless , using the Force she was able to throw her lightsaber at her pack which contained the remaining explosives she had brought with her . The lightsaber set off the explosives and a massive chain reaction perpetuated by the power core , and the explosives she had already placed elsewhere . The resulting explosion was on an enormous scale and completely destroyed the factory , as well as wiping out all of the Separatist forces surrounding it . Aftermath . The success of the battle caused the Separatist forces to lose a vital resource with which to expand their military forces . Nonetheless , the Zaadja factory was but one of many such facilities , and the Republic continued with their designs to further impede manufacturing for the Separatists . The Mandalorian Protectors , allies of the Separatists , also succeeded in hitting the Republic forces hard during the battle . The Battle of Zaadja was also one of many emotional milestones for the young Jedi Anakin Skywalker , who increasingly encountered difficulties with the sacrifices he witnessed . Though he was reluctant to accept it , Skywalker agreed with Tohno ' s decision to end the Zaadja mission with as little loss of life as possible . Nonetheless , Skywalker would continue to struggle with the need for so many young , and promising , Jedi to sacrifice themselves throughout the course of the war . Behind the scenes . The Battle of Zaadja was created by writer Randy Stradley for the comic " " , which is the sixty seventh issue of the " " series of comics . Due to a number of small continuity problems with the 2008 Clone Wars multimedia project , there are some conflicts with what has been established in " Republic 67 " and various items of the project , such as the and ongoing . Due to the fact the new movie , TV series , and other facets of the Clone Wars multimedia project are all set in the first year of the war , the Battle of Zaadja may eventually see re - dating to fit into the first year as well . However , given that nothing within the 2008 Clone Wars multimedia project even mentions this battle , Lucasfilm Ltd . may simply choose to leave the dating as it is . Likewise , established within " Republic 67 " is the fact that Anakin Skywalker is a Jedi Padawan who holds the rank of commander within the Republic ' s military . However , with the release of the Clone Wars movie , Skywalker is a fully fledged Jedi Knight during the first year of the Clone Wars , thus causing another minor continuity problem . To date , there has been no official statement from Lucasfilm Ltd . regarding either the dating situation or the problem with Skywalker ' s Jedi status .
