Second Battle of Roche The Second Battle of Roche was a battle that began as a Jedi Coalition raid , but quickly escalated into a massive battle with the arrivals of the fleets of both Admirals Natasi Daala and Cha Niathal . Prelude . Jaina Solo and her parents were aboard a Hapan Battle Dragon , to report to Luke Skywalker that his son Ben had been captured . On approach , they had noticed many StealthX s , Owool Interceptor s and blastboats with ex - Alliance pilots getting ready for a raid . After Leia informed Luke of Caedus ' presence on Nickel One , Luke finally understood why all the arms convoys the Jedi had been targeting had been protected by the Fourth Fleet . Although he realized that Caedus would sense him coming , Luke couldn ' t change the plans for the upcoming raid , as the Sith Lord would realize Luke was using his own visions against him . Before going to Nickel One , Luke ordered the Owools to stand down , claiming that other escorts would be waiting for them . The battle . After the Jedi strike force arrived they were attacked by Imperial Starhunter s . Luke negotiated with Boba Fett to have his Mandalorian strike team act as their escorts , and the combined force proceeded to attack the Imperial Star Destroyer " Harbinger " as Jaina was launched to Nickel One ’ s surface in a dropsuit . After an encounter with Starhunters attacking the Blastboat , Jaina descended to land on the surface as the Coalition strike force destroyed the " Harbinger " and attacked the command center where Caedus was located , as a means of attracting his attention . Concurrently , the Mandalorians sent two Tra ' kads filled with supercommandos to the command bunker to wipe out the Moff Council . The Blastboat continued towards the command bunker , using the Bes ' uliik escorts as protection against clustermines . Jaina now realized that Luke had used Mandalorians instead of the Owools as their escorts because he had most likely sensed that the escort squadron would take heavy losses . One Tra ’ kad and ten Bes ’ uliks remained as she started towards the command bunker . Assault on the Moffs . The Jedi strike force shattered the bunker ' s observation dome while Jaina destroyed a flak gun and met up with Mirta Gev and her commandos , who were on their way to wipe out the Moffs . Jaina went with them as they had a security camera focused on Caedus in meditation , which suited her purposes . After a stop at the Verpine resistance network , and in spite of Jaina ' s warnings , the Mandalorians attacked the Moffs . Jaina moved to the vantage point of a projection booth , armed with a QuietSnipe rifle , as the commandos began their assault with a surprise attack on the Elite Guard protecting the Moffs . Jaina used the QuietSnipe to aid the commandos by periodically taking down both Moffs and stormtroopers with mag - pellets . The troopers that survived eventually shifted the momentum of the battle and killed three of the commandos . Jaina noticed some grenades thrown by Mirta change their direction in mid - air , and knew that her brother had arrived . Caedus began by raising Mirta into the air and slamming her headfirst into the floor , leaving her unconscious . Jaina couldn ’ t get a shot on Caedus due to his Force - enhanced speed , and could only watch as he wiped out the rest of the Mandalorians , even using the rare shatterpoint ability to smash open Roegr ' s beskar armor . Finally , only Vatok Tawr remained , and after a short duel , he was impaled through his T - visor by Caedus . Jaina was then able to fire off three shots , managing to hit Caedus in the shoulder . After Jaina ' s emptying the QuietSnipe of pellets , Caedus twisted the rifle with the Force , rendering it useless , and lunged into the booth . They both ignited their lightsabers and engaged in a duel . Arrival of Niathal and Daala . Meanwhile , outside the asteroid , Admiral Daala ' s Maw Irregular Fleet and Cha Niathal leading her Alliance - in - exile forces , arrived . They immediately attacked the Remnant fleet who , along with the Fourth fleet , still outnumbered the Coalition forces . Han Solo noticed a frigate that had been chasing them turn away towards Nickel One , moving to regroup with other Remnant forces so they could properly defend the system . Realizing that once the Fourth fleet joined with them it would be impossible to reach Jaina , Han contacted Jagged Fel and made a plan to extract Jaina from the command bunker . They started towards the asteroid ' s surface as they once again came under attack by the frigate . Jaina vs . Caedus . As the two duellists exchanged kicks , it dawned on Caedus just how good his enemy was . As Caedus began to drive his foe back he was able to see their face clearly : it was that of Luke Skywalker . Caedus , deflecting a series of slashes , was perplexed as to how the man he had just sensed high above the planet in a blastboat with his parents could now be in front of him . The fight moved outside of the booth as Caedus had to call upon the Force to bolster the strength of his good arm , while the wounded one remained limp at his side . After trying and failing to hit the disguised Jaina with a dart launcher , she leapt toward Caedus , hoping to end the fight swiftly . But Caedus managed to throw Vatok ' s body into the air , the helmet splitting Jaina ’ s forehead and sending her to the ground . Although for a moment it looked as if she were dead , Jaina promptly rose to her feet and grabbed her friend ’ s beskad saber ; after an exchange of blows she managed to cut off the arm of the Sith Lord . Caedus splashed the blood flowing from the gaping wound onto Jaina ’ s face and neck . Although she was unaware at the time , Caedus had just marked her with a blood trail that would later lead him to the Jedi base . The duel ended as Caedus blasted his sister with Force lightning . Caedus once again saw Jaina ’ s face , and not Luke ' s . He was shocked to see his sister , and demanded to know where Luke was hiding . Jedi withdrawal and the battle intensifies . Stormtroopers then entered the chamber and Caedus ordered them not to fire at Jaina , but Luke Skywalker , who he saw in the corner . Jaina was surprised and puzzled , but used the time to escape with a Verpine technician , while Caedus was rushed to the infirmary . Jaina escaped with her parents and the rest of the Jedi to Shedu Maad . The withdrawal of the Jedi did not end the battle , as the Hapan , Alliance - in - exile and Maw Irregular forces remained committed to the fight . The Fourth Fleet and two Remnant Fleets were trapped in - system when the Confederation forces arrived , the Bothan and Corellian fleets boosting the anti - Caedus forces to six fleets . After a week of conflict , Caedus ' forces remained locked in combat , but the tide of the battle turned when Admiral Nek Bwua ' tu defeated the Alliance - in - exile forces and trapped the Confederation fleets . As a result of the Mandalorian attack , Caedus sent Admiral Atoko and the remains of the Fifth Fleet to bombard Mandalore , and the Imperials would develop a Nanovirus designed to kill Boba Fett and his entire family if they ever set foot on the planet again . Darth Caedus became more certain than ever that killing Luke Skywalker would end the war . To find him he followed the blood trail he ' d left on Jaina with a handful of Remnant ships , the " Megador " and the " Anakin Solo " , while Bwua ' tu defeated the Jedi Coalition fleets . Caedus ' s task force followed the Jedi into the Transitory Mists , which would lead to the Battle of Uroro Station .
