History . Though Commander Cody was the overall commander of the 7th Sky Corps , he later took personal command of the 212th Attack Battalion , which was also led by High Jedi General Obi - Wan Kenobi , who developed a friendship with the battalion commander during the Clone Wars . The 212th was a well - known and effective battalion which would often be sent to participate in major battles during the Clone Wars . The 212th were often deployed alongside the 501st in missions and battles across the galaxy . During the Battle of Christophsis , Commander Cody and the 212th aided Jedi Generals Obi - Wan Kenobi and Anakin Skywalker . After being breached unexpectedly by droid forces , it was soon revealed that one of their brothers was a traitor . Cody helped Rex hunt down the traitor who was none other then Slick . During the Separatist counter attack , the 212th Battalion , along with Torrent Company , helped beat back droid forces . In the Battle of Teth , the battalion , led by Cody , went with Kenobi to aid Anakin Skywalkerand the remainder of Torrent Company which had been overrun by droid forces , and later defeated the droid forces under command of Asajj Ventress . In the Battle of Ryloth , Ghost Company helped Kenobi eliminate several proton cannons to allow ground invasion forces to land . After encountering starved gutkurrs , the squad created a diversion while Kenobi and troopers Waxer and Boil helped the general destroy the cannons , allowing the " Acclamator " assault ships to land and initiate the invasion . Republic troops would later march to the capital city of Lessu , liberating the planet from Separatist enslavement . In the Second Battle of Geonosis , General Kenobi , Cody and the 212th were assigned to lead the central charge upon landing . They were the first to land on Geonosis , while the 501st and Ki - Adi - Mundi ' s battalion were forced to land before reaching their landing zones and rendered them unable to provide support . When Kenobi ' s gunship crashed behind enemy lines , Cody sent Waxer and Boil to retrieve Kenobi and return with the wounded Jedi Master . The 212th , though vastly outnumbered and forced onto the defensive , lined up their gunships and AT - TEs in a circle formation and used them as gun emplacement platforms to hold the encircling droid forces at bay . The 212th were able to hold out against the Geonosians and their droid forces , albeit with significant casualties , until Generals Skywalker ' s 501st and Ki - Adi - Mundi ' s forces finally arrived with air support . Due to sustaining numerous casualties , the 212th would not participate in the following attack on the Geonosian capital . In the Battle of Umbara , General Kenobi and the 212th spearheaded the Republic ground attack , going straight for the Umbaran capital while the 501st provided support by eliminating enemy supplies . Obi - Wan called on General Pong Krell , who was the interim commander of the 501st in Skywalker ' s absence , to help aid the siege through various means , such as destroying an Umbaran airbase . While the majority of 212th forces sieged the Umbaran capital itself , Krell ordered a platoon led by Waxer to search the forests for enemy guerrillas disguised in 501st armor , unaware that the 501st were given the same order . The 212th and 501st cut each other down with blaster fire and mortars until the captain in charge of the 501st realized they were shooting at fellow clones . Waxer had been fatally wounded but was able to tell Rex that Krell gave the order . The survivors of the platoon joined the 501st in attacking and capturing , at great cost , the traitor , General Krell . Later , the main forces of the 212th successfully took down the capital and dispatched squadrons to destroy the remainder of seperatist forces on Umbara , including the droid battalion which was en route to attack the Umbaran airbase captured by the 501st , effectively ending the Battle of Umbara . During the Attack on Obi - Wan Kenobi ' s fleet , the 212th aided the 211th Battalion in the unsuccessful attempt of repelling Seperatist forces from the Negotiator , failing due to the superior number of droids and the presence of Grevious . Most of the battalion escaped via escape pods after General Obi - wan Kenobi ordered a retreat . The 212th was sent to Sarrish in an attempt to neutralize Separatist forces on the planet . Although the 212th initially managed to push back the enemy , the Separatist ' s superiority in numbers and their geographical advantage gradually forced back the 212th forces , instigating heavy casualities in the process .

On Cato Neimoidia , General Kenobi , Commander Cody , and the elite Squad Seven breached Trade Federation Viceroy Nute Gunray ' s fortress and secured vital data that began the hunt for Darth Sidious . When General Kenobi was tasked with tracking down and eliminating the Separatist Supreme Commander , General Grievous , he took two battalions with him to the Utapau system — the 212th and the 211th Battalion . Cody ' s commandos stormed Grievous ' s stronghold on the tenth level of Pau City , and kept his droid forces at bay while Kenobi faced the General himself in single combat . The clones would take heavy casualties in the battle due to the superior numbers of droids , but would eventually gain the advantage , and later destroyed all the droid forces stationed on the planet . Although Obi - Wan defeated Grievous , matters took a turn when Darth Sidious transmitted Order 66 to Cody . Cody was ordered to command an AT - TE walker to open fire on the general , sending him to his apparent death hundreds of feet below .
