Battle of Ottega ( Zaarin insurrection ) The Battle of Ottega was a battle fought during the Galactic Civil War in the Ottega system . This battle was expected as the simple elimination of all traitorous Admiral Harkov ' s remaining forces but turned as the beginning of the Grand Admiral Zaarin Insurrection . Prelude . Following the execution of Admiral Harkov , the Galactic Empire decided to eliminate Harkov ' s remaining forces . The remnants of his fleet , more specifically the " Victory " - class Star Destroyer " Protector " had successfully been located in the Ottega system . The warship had stopped in the where Rebel forces had left cargo containers with which to supply the remaining traitorous forces . Darth Vader dispatched a fleet led by the " Imperial " - class Star Destroyer " Garrett " and including the " Interdictor " cruiser " Harpax " in the system . The battle . Trap the Protector . The " Harpax " entered the system near the " Protector " , activating its gravity well projectors in order to keep Harkov ’ s fleeing associates from escaping . Two flight groups of TIE Avenger starfighters deployed with the " Harpax " , ordered to destroy the cargo containers to halt the traitor ’ s re - supply efforts and protect the vulnerable " Harpax " from counterattack until additional Imperial forces could arrive . Emerging from hyperspace , the TIE Avengers " Alpha " encountered TIE / IN interceptors " H - Delta " barreling down on them , warhead launchers armed . Splitting their flight group , Avengers " Alpha " proceeded to destroy the Rebels ' containers as their wingmen handled the harassing TIE / LN starfighter s , TIE / IN interceptors , TIE / sa bombers , and Avengers . Imperial starfighters quickly succeeded in destroying the supply cache , moving on to fend off enemy fighters . Avengers " Alpha " rallied back towards the " Harpax " , awaiting additional Imperial forces to arrive . Remaining traitorous TIEs continued to pursue , joined by the Mon Calamari MC40a light cruiser " Warhawk " . Z - 95 Headhunters and T - 65 X - wing starfighter s soon joined the battle , originating from the " Warhawk " , and began attacking the " Harpax " . Moments later the Nebulon - B frigate " Akaga " also emerged from hyperspace , launching more Z - 95s . Imperial TIE Avengers acted swiftly to eliminate the impending threat on Interdictor " Harpax " as Z - 95 Headhunters from the " Akaga " began firing proton rockets and bombs . Avengers managed to intercept incoming warheads with laser cannonfire between eliminating the rest of the starfighter threats . The Assault Transports " Lambda " arrived on the scene , followed by Avengers " Alpha " and " Beta " , who returned to their hangars for the next assault . Destroy the Akaga . With the arrival of the frigate " Akaga " , Imperial pilots from TIE Avenger " Alpha " returned to the field to defend the Interdictor . Expecting the arrival of Darth Vader aboard the " Imperial " - class Star Destroyer " Garrett " , TIE Avengers " Alpha " entered the system armed with space bombs to destroy the " Akaga " . " Alpha " delivered the first devastating blow to " Akaga " , lowering the warship ' s shields with a single volley of space bombs . Prepped for reload operations , the " Delta " - class DX - 9 stormtrooper transport " Goya " arrived as Avenger ' s warhead magazines ran dry . Avengers " Beta " and " Gamma " covered attack operations on the " Akaga " by intercepting incoming enemy TIEs and Z - 95 Headhunters . Members of " Alpha " flight conducted docking operations until the " Akaga " collapsed under their massive wave of missiles . With the frigate out of the way , Imperial Avengers continued their mop up operations as the " Garrett " arrived . The pace of the operation hastened with Darth Vader on - station ; Imperial pilots reported to the " Garrett " to prep for the next phase of the attack . Retribution . Maarek Stele and his wingmen were sent out again , once more in TIE Avengers , this time to remove the " Protector " and the " Warhawk " before they could destroy the " Harpax " and escape . Neither ship had any remaining fighters , leaving a fairly simple task for Stele ' s flight group . Targetting the " Warhawk " first , the cruiser was soon destroyed , and the Imperials turned their attention to the " Protector " . At this point , some " Alpha " - class Xg - 1 Star Wings arrived . This was the first part of a force sent by Grand Admiral Demetrius Zaarin , supposedly to help the Imperials in the area . However , the Gunboats targeted the TIE Avengers of Stele and his colleagues . As the TIE Advanced bore down on the " Protector " , Zaarin ' s " Assassin " - class corvettes arrived , followed by some " Gamma " - class ATR - 6 assault transports . However , instead of turning to attack the " Protector " , they began to fire on the " Garrett " and the other loyal Imperial craft . The Immobilizer 418 cruiser , " Harpax " , which had been fleeing from the battle , was caught by part of the traitor ' s forces . Having been damaged in the previous engagements , the interdictor was destroyed , allowing the " Protector " , under a barrage of torpedo fire , to power up its hyperdrive . Its escape attempt was in vain , however , as Stele finished the defecting Star Destroyer personally . Having done so , a small Rebel force , consisting of two CR90 corvettes , two " Delta " - class JV - 7 escort shuttles and some B - wing starfighters arrived , but this was ignored as Zaarin ' s forces posed a greater danger to the " Garrett " . Stele led an attack on Zaarin ' s forces , destroying their entire strength while taking minimal casualties . With the traitors destroyed , Stele finished off the Rebel force , before landing on the " Garrett " . Aftermath . Having discovered Zaarin ' s treachery , Darth Vader decided to rush to Coruscant to prevent Zaarin ' s attempted coup . But the " Garrett " was too damaged to travel to the Imperial Center . Vader chose five elite pilots , including Maarek Stele , to assist him in flying six TIE / D Defenders to Coruscant . Behind the scenes .

The battle is depicted in the three first missions of the game ' s seventh tour of campaign , " Treachery at Ottega " .
