Battle of Felucia ( Outer Rim Sieges ) / Legends The Battle of Felucia occurred late in the Clone Wars , part of the Outer Rim Sieges . It was initially a mission assigned to the 182nd Legion of the Grand Army of the Republic to combat the Separatist forces which had taken control of the planet . When contact with the 182nd was lost , the 501st Legion of elite clone troopers was deployed to investigate their disappearance . After the 501st secured the area , the 327th Star Corps under the command of Jedi Master Aayla Secura and Marshal Commander CC - 5052 arrived and began a manhunt for President of the Commerce Guild , Shu Mai , who was believed to be holding Jedi Knight Barriss Offee prisoner . Following her rescue , the battle quickly shifted to an attempt to stop the spread of deadly toxins from contaminating Felucia ' s water supply . In the midst of the battle , the Order 66 protocol issued by Supreme Chancellor Palpatine was received , and the Jedi were shot dead by their own men . Prelude . Earlier in the war , General Grievous of the Confederacy of Independent Systems led an assault on Felucia and secured the planet for the Separatists . The Jedi Plo Koon , Anakin Skywalker , Obi - Wan Kenobi , and Ahsoka Tano , Anakin ' s Padawan , were sent to save the planet . However , the clone trooper force was greatly outnumbered and the Jedi were forced to retreat , failing in their mission . The battle . It began with the landing of the 182nd Legion which , after some time , the Republic lost contact with . Therefore , elements of the elite 501st Legion were deployed to begin routing the Separatist army from the planet . The very first phase of the battle was the 182nd Legion attacking the Felucian blockade by the CIS . They were taken out with mild difficulty . Yet when they landed on the surface , they were overrun and called in the 501st Legion for help . Upon arrival however , the 501st quickly found that Felucia had a nightmarish topography . With dense foliage and seemingly infinite jungles and spores , ambushes were common , and heavier support vehicles were hard to use . The 501st sent a patrol to scout ahead , but their transmission was abruptly cut off by blaster fire , screams and an unearthly screeching noise . Moving forward , the troopers encountered a number of feral acklay , which had decimated the patrol . Rockets and mines were used to great effect , but the group suffered heavy casualties . Two gunships tried to land to reinforce the group , but one gunship was shot by AA guns and crashed in the brush nearby . 501st members protected an AT - TE from super battle droids and assault droid s for some time . About fifty advanced down the hill . They attempted to destroy the vehicle with rockets , but it had little effect , and that made the droids easy targets for the clones . After the onslaught , the clones repaired the vehicle by taking a power cell from the downed Republic gunship and using it to re - power the walker to make use of it . Eventually Jedi General Aayla Secura arrived on Felucia , and was able to lead the 501st contingent to rout the Separatist defenders at a high cost of troops . It was here that Secura dubbed the 501st " the bravest men she had ever seen " . Armed with dual lightsabers , Secura cut through the droid ranks to recover a powercell from the crashed gunship and powered up the walker , causing devastation to the CIS tanks advancing on their position . The Republic troops then preceded to destroy six Anti - Vehicle turrets that were causing damage to Republic forces from the area near the fungal tree , and moved on . As part of the hunt for Commerce Guild President Shu Mai , Aayla Secura and her troops arrived at the Nigkoe Detention Facility where they believed Jedi Knight Barriss Offee was being held prisoner . Attacking the facility , the clone troopers , under the command of Clone Commander Bly , engaged the Gossam Commandos and secured the area while Secura freed both Offee and her Selonian Padawan Zonder . Still on the trail of Mai , Jedi Generals Aayla Secura and Barriss Offee along with the 327th Star Corps clone troop infantry under the command of Bly , arrived at her heavily fortified compound outside of Kway Teow . After creating a diversion that destroyed several B2 super battle droid guards , the Jedi and clones advanced on Aratech BARC speeder bikes toward the compound . They were attacked by several droid starfighters , but these were dealt with by a Republic squad of ARC - 170 starfighters . Having entered the compound through a lake and waterfall - access , and let their troops inside , Aayla Secura , Barriss Offee and their Padawans Ekria and Zonder found that their search was for naught ; Shu Mai ’ s personal ship had left days ago and no one had entered or left the compound since . While gathering information on the ongoing attack on Coruscant , the Jedi were informed by Commander Bly that the compound was filling up with toxins . A countdown sequence had also begun , which prompted Secura to order a full withdrawal from the area . Moments before the compound exploded , the Jedi and their troops managed to escape . A clone trooper task force of the 327th Star Corps infantry , under the command of Jedi General Aayla Secura , prepared to attack several of Felucia ' s water treatment facilities to prevent the Gossam homeworld from being infected by a toxin released into the water supply . This situation had come about due to a self - destruct mechanism designed by President Mai . The clone trooper reinforcements , brought in by Jedi General Stass Allie , who then went on to Saleucami , were briefed on the situation by Commander Bly . It was stated that Felucia ' s defenses were heaviest against air assault , thus a ground attack would be most effective . Since the jungle would slow them down , Jedi Knight Barriss Offee would lead one squad to Har Gau , while a second squad , led by Jedi Padawans Ekria , Zonder and the newly - arrived Drake Lo ' gaan , would target Jiaozi . General Secura ’ s squad would accompany the Padawans and then proceed to Niango . The 327th Star Corps task force then split up and headed into the woods . As the Padawans ' force reached Jiaozi , they staged a diversionary attack and withdrawal , to lure the guards away from the water treatment facilities and allow the three Jedi access . The toxins were restrained from spreading further , but remote access to the other stations was impossible , as they each were on an isolated network . Padawan Ekria then tried to raise Generals Secura and Offee , but failed as the transmissions were being jammed . In an attempt at finding out the state of the other forces , Ekria gained access to cameras installed inside clone trooper helmets . This feat might possibly have saved the three Padawans from certain death , as Order 66 was given a few minutes later . When the order was given , Barriss Offee was under siege from B - 2 battle droids . Having seen Lieutenant Galle arrive with reinforcements , she ordered him to open fire . She was subsequently shot to death by an AT - TE walker and her own troops . Aayla Secura had stopped on her way to Niango , due to reports of a Separatist armored unit in the area . As her troops waited , Secura was distracted by a bird suddenly taking flight , while at the same moment Commander Bly received Order 66 and proceeded to shoot his commanding officer in the back before she could even react . Aayla Secura was finished off by concentrated fire from the clones surrounding her . Aftermath . Having witnessed the slaughter of their seniors , the three Padawans situated at Jiaozi water treatment facilities managed to escape their own troops and fled the planet . After containing the toxins and saving the planet , the newly established Galactic Empire absorbed Felucia into its control .
