Rescue on the Imperial Interdictor During the early rebel movement against the Galactic Empire , two rebels — the Jedi Kanan Jarrus and Clone Captain Rex — carried out a rescue mission on the experimental Imperial Interdictor . Their objective was to rescue Commander Jun Sato , Padawan Ezra Bridger , and other rebels from the Phoenix Cell , who had been captured when the Interdictor used gravity well projector s to pull their ship out of hyperspace . Jarrus and Rex were successful in their operation , and , with the help of Bridger and the astromech droid Chopper , the rebels destroyed the experimental vessel to prevent it from disrupting the movements of the rebel fleet . Prelude . In 4 BBY , the Galactic Empire developed a new prototype Interdictor vessel called the Imperial Interdictor . Since the vessel was still in its experimental stage , the Empire tested the vessel in a remote system called the Del Zennis system . During the testing period , the vessel was commanded by Admiral Brom Titus . Around that time , a rebel patrol ship disappeared in the Del Zennis system . In response , Commander Jun Sato and several rebels including the Jedi apprentice Ezra Bridger traveled on the CR90 corvette " Liberator " to investigate the disappearance . While traveling through the Del Zennis system , the " Liberator " was pulled out of hyperspace by the Imperial Interdictor ' s gravity well projector s . The Imperials then proceeded to freeze the ship ' s controls and to jam its communications . Despite the jamming , Commander Sato still managed to issue a distress call to the Phoenix Cell that his ship had been pulled of hyperspace by an unknown Imperial weapon . Shortly later , the " Liberator " was boarded and its crew were captured by stormtrooper s . Admiral Titus recognized Commander Sato and Ezra as wanted rebels . After receiving word about Ezra ' s Force - sensitivity from Agent Kallus , Sato ordered three of his men to send Ezra into a secure cell . Sato ' s distress call was received by the rebel ship " Ghost " , the base of operations for the Spectres . Sabine Wren , a former Imperial cadet , rightfully suspected that the Empire was developing a new Interdictor cruiser . While Ezra ' s master Kanan Jarrus recommended sending the entire crew to rescue Ezra and the Phoenix rebels , the " Ghost " captain Hera Syndulla had another plan . She proposed that Kanan and the former Clone Captain Rex disguise themselves as stormtroopers and infiltrate the Imperial Interdictor in a stolen Imperial shuttle . The astromech droid Chopper would also come along disguised as an Imperial droid . The rescue mission . Infiltrating the Imperial Interdictor . Despite Kanan ' s distrust of clone trooper s due to the Jedi Purge , he reluctantly agreed to work with Rex for the good of the rebel cause . Upon reaching the Del Zennis system , Rex managed to obtain permission to dock with the Imperial Interdictor by claiming that their shuttle was experiencing an emergency . After landing in the ship ' s hangar bay , Kanan used a Jedi mind trick to trick the stormtrooper sentries into letting them through . Meanwhile , Ezra managed to break free of his stormtrooper captors by using the Force to activate his lightsaber - blaster ; startling the guard . Ezra then locked his three captors in a secure cell . Shortly later , Kanan and Rex arrived . Not recognizing his fellow rebels due to their Imperial armor , Ezra stunned them with his lightsaber - blaster . Upon seeing Chopper , Ezra realized his mistake . When Kanan and Rex stirred , he claimed that they had been caught up in a firefight . However , Chopper soon produced a holographic recording of Ezra shooting them . Having rescued Ezra , the rebels then split into two . While Kanan and Rex proceeded to rescue Commander Sato and the other prisoners , Chopper and Ezra decided to sabotage the ship ' s gravity well projectors . Meanwhile , Admiral Titus received word that Ezra had escaped and ordered his men to secure all levels and the hangar bays . He also gave orders for Ezra to be killed on sight in order not to prove Agent Kallus right about underestimating the rebel youth . In the ship ' s reactor core , Ezra managed to distract the Imperial technicians while Chopper switched off the gravity field . After sabotaging the gravity well projectors , Chopper reactivated the gravity field ; sending the Imperials crashing below . Ezra narrowly escaped the skirmish and joined Chopper in fleeing the stormtrooper reinforcements . The Great Escape . Elsewhere aboard the Imperial Interdictor , Kanan and Rex managed to free Commander Sato and his crew . While making their way back to the " Liberator " , they were pursued by several stormtroopers . As the other rebels fled through a blast door , Rex stayed behind to hold off the Imperials . Despite putting up a fierce fight , he was stunned by a stormtrooper and taken prisoner . Meanwhile , Ezra and Chopper managed to reunite with Kanan , Sato , and the rebel crew . While Ezra helped Commander Sato and his crew fight their way back to the CR90 corvette , Kanan went back to rescue Rex . Meanwhile , Admiral Titus summoned Rex to his chambers . Upon learning of the Clone Captain ' s honorable record , he offered Rex amnesty in return for convincing the other rebels to surrender . When Rex refused to serve the Galactic Empire , Titus ordered an interrogator droid to tortured the Clone veteran to death . Before Titus could complete the execution , Kanan entered the chambers disguised as a stormtrooper and attacked Titus ' men . Having rescued the wounded Rex , the two Clone Wars veterans escaped the Interdictor aboard an escape pod . After breaking free of the Imperial Interdictor , Commander Sato ' s CR90 corvette attempted to jump into space . However , Admiral Titus ordered his crew to activate the Interdictor ' s gravity - well projectors . The gravity well - protectors then suddenly malfunctioned and began attracting every nearby object including the Interdictor ' s two escort " Arquitens " - class command cruisers . The CR90 corvette managed to break free of the gravity well but the Imperial Interdictor and its escort ships were destroyed in a cataclysmic explosion . Aftermath . The destruction of the Imperial Interdictor was another victory in the rebellion ' s struggle against the Galactic Empire . The rebels not only succeeded in rescuing their captured comrades but also managed to deprive the Empire of another weapon . While Commander Sato praised Kanan , Rex , and Ezra for rescuing them , he neglected to mention Chopper ' s role . When Chopper hooted , Ezra assured him that it was a team effort . Unknown to the rebels , Admiral Titus survived the destruction of the Imperial Interdictor and its escort ships by fleeing into an escape pod . However , many Imperial personnel were killed during the explosive . Shortly later , Agent Kallus arrived with a fleet of Imperial Star Destroyers . When a humiliated Admiral Titus contacted Kallus via hologram , Kallus mockingly asked the Admiral whether he had any problems with the boy . For the Empire , the destruction of the Imperial Interdictor was one in a chain of losses against the rebellion . Behind the scenes .
