Separatist Droid Army The Separatist Droid Army was the ground army force of the Confederacy of Independent Systems during the Clone Wars , part of the Confederacy military . The army was mostly built by Baktoid Combat Automata and led by the Kaleesh cyborg General Grievous . According to Count Dooku , Head of State of the Confederacy , at the start of the conflict in 22 BBY the Droid Army out numbered the Republic ’ s clone army one hundred to one . In addition to this opening amount of droid s , the Separatists continued to produce droids throughout the war , a notable example being in 21 BBY when they ordered more than three million battle droid s with the InterGalactic Banking Clan helping to finance this order . The army was deactivated after the Clone Wars , when Darth Sidious rose to power as Emperor of the Galactic Empire . History . Origins . During the Separatist Crisis , Count Dooku ' s emerging Separatist movement secretly manufactured a droid army in the droid factories of the planet Geonosis . The Separatist movement was supported by the Trade Federation , the Commerce Guild , the Techno Union , the InterGalactic Banking Clan , and the Corporate Alliance . The secret droid army was discovered by Jedi Master Obi - Wan Kenobi , whose capture triggered an attack by the Jedi Order and the Galactic Republic ' s secret Grand Army of the Republic , which had been commissioned by Master Sifo - Dyas . The outbreak of the Clone Wars played into the hands of Darth Sidious , who masterminded the conflict while simultaneously serving as Supreme Chancellor of the Republic . During the conflict , the Separatists continued to produce droids , and in 21 BBY , they ordered an additional three million battle droid s with financial backing by the InterGalactic Banking Clan . 22 BBY . Following the Battle of Geonosis in 22 BBY , the Separatist Droid Army saw action against the Jedi and the Grand Army of the Republic on numerous fronts and worlds across the galaxy including Hissrich , Christophsis , Ryloth , Maridun , and Felucia . On Maridun , Separatist droid forces led by Lok Durd attempted to test the Defoliator weapon on Lurmen migrants but were repelled by the Republic and Jedi led by Jedi General Aayla Secura , General Anakin Skywalker , Commander Ahsoka Tano , and Commander Bly , and Captain Rex . Later , General Grievous , the Supreme Commander of the Droid Army , was ambushed by Jedi and Republic forces led by General Kit Fisto . Grievous survived the attack and Fisto was forced to flee . The ambush was a test engineered by Dooku to test Grievous ' worthiness to lead the Droid Army . Elements of the Droid Army also guarded Separatist scientist Nuvo Vindi ' s secret laboratory on Naboo , which manufactured stockpiles of the deadly Blue Shadow Virus . On Ryloth , Separatist droid occupation forces faced resistance from Cham Syndulla ' s Twi ' lek Resistance , who were backed by the Jedi and Republic . 21 BBY . By 21 BBY , the Separatists had recaptured Geonosis and begun producing more battle droids for their Droid Army . In response , the Republic sent a Clone army led by Jedi Generals Ki - Adi - Mundi , Kenobi , Luminara Unduli , and Skywalker to retake the planet , culminating in the Second Battle of Geonosis . Following fierce fighting , the Republic succeeded in destroying the Geonosis primary droid foundry , killing Karina the Great , and capturing Poggle the Lesser , dealing a major blow to the Separatist war effort . After General Grievous kidnapped Jedi Master Eeth Koth , the Jedi and Clone troopers pursued the Supreme Commander and his contingent of battle droids to Saleucami .

During the battle , the Droid Army ' s forces included Aqua droid s and aquatic " Trident " - class assault ships . Despite a vigorous attack , the Separatist were repelled by Clone and Jedi defenders . As part of a conspiracy to derail Separatist Senator Mina Bonteri and Republic Senator Padmé Amidala ' s efforts to forge a peace agreement between the two states , Count Dooku and General Grievous dispatched Demolition droid s to bomb Coruscant ' s Central power distribution grid ; undermining Bonteri and Amidala ' s efforts to seek a diplomatic solution to the Clone Wars . 20 BBY . In 20 BBY , Separatist Droid Army forces under the Karkarodon Commander Riff Tamson joined forces with the Quarren Isolation League to oppose the succession of the Mon Calamari Prince Lee - Char , who was backed by the Republic and Jedi .

Tamson ' s Trident assault ships later neutralized Gungan reinforcements led by Jar Jar Binks . Despite capturing most of the opposing Republic and Mon Calamari forces including Prince Lee - Char , the Separatist forces were defeated when the Quarren leader Nossor Ri convinced his people to unite with the Mon Calamari and Republic to expel Tamson ' s droid forces . Count Dooku later attempted to forge an alliance with the Gungans using his local collaborator Rish Loo , who bewitched Boss Lyonie . This Separatist plot was foiled by Binks and Roos Tarpals , who succeeded in capturing General Grievous . However , the Gungans and Naboo were forced to release the Separatist Droid General when Dooku threatened to execute General Skywalker . Later , the Droid Army invaded the Togruta colony of Kiros and sold the colonists as slaves to the Zygerrian Slave Empire . General Grievous subsequently commanded the Droid Army ' s attack against the Nightsisters of Dathomir , whom Count Dooku regarded as a growing threat to the Sith . During the assault , Grievous slew Mother Talzin while the droids killed many Nightsisters . During the Onderonian Civil War , Separatist droid forces under the Super tactical droid General Kalani later propped up the pro - Separatist regime of King Sanjay Rash of Onderon in the Inner Rim .

After winning the support of the rightful King Ramsis Dendup and General Tandin , the Onderon rebels succeeded in expelling Separatist forces from Onderon . Separatist droid forces were also attacked by the local population in the capital Iziz . General Kalani and the surviving droids retreated to the Outer Rim planet Agamar . In retaliation for the Ohnaka Gang ' s mistreatment of Count Dooku years earlier , Separatist droid forces under General Grievous attacked Hondo Ohnaka ' s pirate base on Florrum and laid waste to it . Tano and six Jedi youngling s fought against Grievous and his forces but were forced to retreat . 19 BBY .

After Count Dooku pressured Rush Clovis , the new head of the InterGalactic Banking Clan , to raise interest rates on the Republic , Separatist droid forces attacked Clone Commander Thorn ' s forces on Scipio . When the Galactic Senate voted to invade Scipio , Dooku promptly withdrew Separatist forces from the planet . The capture of Scipio gave the Supreme Chancellor control over the banks ; placing the galactic economy under the control of the Sith . Later , two of Grievous ' IG - 100 MagnaGuard s assassinated Jedi Master Tu - Anh on the neutral world of Utapau . While investigating Tu - Anh ' s death , Master Kenobi and Jedi Knight Skywalker fought the two MagnaGuards and discovered that the Separatists were interested in acquiring a large kyber crystal through several Sugi mercenaries led by Endente . After Kenobi and Skywalker stole the crystal , General Grievous brought several droid forces including B1 battle droids and MagnaGuards to recover the crystal . Despite Grievous evacuating the kyber crystal offworld , the Jedi managed to destroy the crystal and a Separatist supply ship . The Separatist Droid Army also fought an extended campaign against the Republic on the Core World of Anaxes . Admiral Trench was aided by the Techno Union ' s Foreman Wat Tambor who used an unconscious Clone trooper " Echo " to provide the Separatists with an algorithm on the Republic ' s strategies . Echo was rescued by Clone Force 99 , General Skywalker , and Rex who fought Tambor ' s D - wing droid s and Octuptarra tri - droid s with the help of the Poletec s of Skako Minor . With the help of Echo , Skywalker and the Clones infiltrated Trench ' s flagship and disabled his droid army on Anaxes , turning the tide of the battle in favor of the Republic . After escaping from the Spire prison , Darth Maul ' s Shadow Collective inflicted heavy casualties on the Droid Army at the Battle of Zanbar before retreating . The Shadow Collective later lured Count Dooku and General Grievous into a trap on Ord Mantell . Separatist ground and space forces were decimated during the battle and the two Separatist leaders were captured by Maul and his allies . Maul ' s Shadow Collective was later defeated by Separatist forces with the help of Darth Sidious at Dathomir . Following the death of Count Dooku at the Battle of Coruscant , the Separatist Droid Army battled the Grand Army of the Republic on numerous fronts including Kashyyyk , Utapau , Saleucami , Mygeeto , Felucia , Cato Neimoidia , Mandalore , and Kaller . These battles coincided with Palpatine ' s initiation of Order 66 , which led to the Jedi Purge . Palpatine than transformed the Galactic Republic into the Galactic Empire . Palpatine then sent his new apprentice Anakin Skywalker , who had assumed the persona of Darth Vader , to execute the Separatist Council on Mustafar . Vader also transmitted a signal deactivating the battle droids of the Droid Army , ending the Clone Wars . Legacy . Despite the deactivation of the Separatist Droid Army , its legacy still lived on in battle droids that survived the Clone Wars . After the Clones Wars various Separatist holdouts survived and attempted to fight the Empire . During the Imperial Era , group of battle droids under the leadership of General Kalani inhabited the wreckage of a DH - Omni Support Vessel on the planet Agamar . Believing the deactivation signal was a Republic trick , Kalani had overridden the command signal , preventing the shutdown of his droid forces . In 2 BBY , he encountered the former Clone Captain Rex , the Jedi Purge survivor Kanan Jarrus , and his Padawan Ezra Bridger . Still believing that the Clone Wars had not ended , Kalani organized a final battle with his prisoners . The rebels managed to break through Kalani ' s lines and Ezra managed to convince Kalani and Rex to put aside their differences in order to escape Imperial forces . This cooperation informally ended the Clone Wars and allowed Rex and Kalani and his droids to make peace with the past . Another holdout during the reign of the Galactic Empire was the holdout on PM - 6986 , led by JF - 86 . After the Battle for Anaxes and a cataclysm that destroyed the planet , a droid army survived on a Separatist stronghold on what would become the planetoid PM - 6986 . Awoken by a Separatist signal that originated light - year s away , JF - 86 proceeded to reactivate the rest of the droid army . Following its last orders , JF - 86 sought to destroy the Galactic Senate of the Republic , unaware of the events in the galaxy and the transformation of the Republic into the Empire . JF - 86 was not able to carry out its plan however , as it possessed no starship s to ferry its troops , and as such , was forced to remain on the planetoid , waiting for an opportunity .
