Battle on Garel During the early rebellion against the Galactic Empire , in 3 BBY , Imperial Military forces launched a battle against the Phoenix Cell on the Outer Rim planet of Garel . The Empire learned of the rebellion ' s location in the Garel City Spaceport after Ezra Bridger , a Padawan in the rebellion , was overheard talking about the rebel ' s location . Agent Kallus of the Imperial Security Bureau and Admiral Kassius Konstantine of the Star Destroyer " Relentless " led the assault against the rebels , while the Inquisitors known as the Seventh Sister and the Fifth Brother sought out Bridger and his master , Kanan Jarrus . At least one rebel transport was downed during the rebellion ' s retreat from Garel , but , due to the pilot ing of Captain Hera Syndulla of the " Ghost " , the Empire ' s tractor beam was disabled and the rebellion was able to escape from the planet and into hyperspace . Prelude . Following the Duel in Hammertown , the two Inquisitors known as the Seventh Sister and the Fifth Brother discovered that the rebellion had a presence on the planet Garel . The Inquisitors shared this information with the Imperial Security Bureau Agent Kallus and Admiral Kassius Konstantine . Kallus , who was a perennial opponent of the Spectres , urged the different Imperial officials to work together to crush the rebels . He then ordered Admiral Konstantine to redeploy the Imperial fleet from Lothal to Garel . Prior to the planned assault , the Imperial authorities on Garel withdrew their stormtrooper patrols in Garel City in order to lull the rebels into a false sense of security . The planned Imperial attack on Garel was preceded by an uprising in an Imperial prison . Ephraim and Mira Bridger , the parent s of the Jedi rebel Ezra Bridger , had been inspired by their son ' s broadcast earlier to launch a prison breakout . The prison uprising succeeded in freeing many prisoner s , including former Lothalian Governor Ryder Azadi , but the Bridgers were killed during the escape . Meanwhile , on Garel , Ezra experienced a Force vision of his parents and the impending Imperial attack . Ezra informed the rebel leaders Hera Syndulla and Kanan Jarrus about his vision . Hera and Kanan , who had just received news about the prison uprising on Lothal , decided to tell Ezra what Tseebo had shared with Hera earlier . Tseebo had told Hera that Ezra ' s parents were imprisoned within a network of Imperial prisons , but they were unsure which one it was . Hera later informed Ezra that Commander Jun Sato ' s contact in the Core had sent him news of a mass breakout from an Imperial prison the night before , and Ezra realized that due to his vision , his parents were likely involved . After scanning a list of prisoners involved in the escape with the Force , Ezra picked out " Prisoner X - 10 " . The Empire had deleted the prisoners ' names and faces , so they did not know that this prisoner was Governor Azadi . Believing that the prison uprising and his Force vision were related , Ezra decided to travel to Lothal . After Sabine Wren received intelligence that the Imperial fleet above Lothal had departed , the Spectres made preparations to leave Garel . While shopping for supplies , Garazeb Orrelios and Chopper reported that they had not encountered any patrols . However , Sabine , as a former Imperial cadet , knew that the Empire always withdrew their patrols prior to a military operation , and rightfully suspected that an Imperial assault on Garel was imminent . Assault on Garel . Shortly later , Zeb and Chopper found themselves pursued by a stormtrooper patrol . Meanwhile , a fleet of Star Destroyer s hovered over Garel City . While waiting for Zeb and Chopper to return , Hera ordered Sabine to slice their jamming system in order to hamper the Imperials ' efforts to locate the rebel ships . Zeb and Chopper managed to reunite with Kanan and Ezra in their hangar bay but were forced to fight off several stormtroopers led by Agent Kallus himself . Giving into his rage , Ezra used the Force to hurl Kallus against a wall . Kallus was followed by the Fifth Brother and the Seventh Sister , the latter of whom attempted to goad Ezra into a lightsaber duel . Before Ezra could respond , Kanan used the Force to shoot out the blast door controls , closing it in front of the Inquisitors . Reunited , the Spectres boarded the " Ghost " and managed to fight off a group of stormtroopers . Once airborne , Hera gave orders for Phoenix Squadron to abandon Garel . As the rebel fleet fled into the skies of Garel , Admiral Konstantine ordered his crew to prepare the tractor beam to intercept the rebel ships . At least one rebel ship was also hit by an Imperial laser blast and crashed into the streets of Garel . Phoenix Squadron Commander Jun Sato and Rex ' s CR90 corvette " Liberator " was intercepted by Konstantine ' s Star Destroyer " Relentless " and trapped by the warship ' s tractor beam . Meanwhile , Hera instructed Kanan , Ezra , and Chopper to leave for Lothal on the " Phantom " . The " Phantom " then took advantage of a momentary gap in the Imperial formation to flee into hyperspace . Meanwhile , Hera responded to Sato and Rex ' s distress call by flying the " Ghost " towards the " Relentless " in an attempt to knock out the tractor beam projector . Just as Sabine had acquired a torpedo lock on the tractor beam projector , a TIE blast knocked the ship out of alignment before she could fire . Undaunted , Hera then undertook a dangerous maneuver which involved ramming the " Ghost " against the projector , knocking it off the " Relentless " hull . The projector then collided with a TIE fighter . With the " Liberator " free , the " Ghost " and the Phoenix rebel fleet was able to jump into hyperspace . Aftermath . Despite their efforts , the Galactic Empire failed to capture most of the rebel fleet hiding on Garel . Most of the Phoenix rebel fleet managed to escape into hyperspace . However , the rebels also suffered serious losses including at least one ship . Upon learning about the Phoenix rebels ' losses , Alderaanian Senator and rebel leader Bail Organa sent his adopted daughter Prince ss Leia Organa to deliver three " Sphyrna " - class corvette to reinforce the Phoenix forces . In order to hide Alderaan ' s links to the rebels , Leia arranged for the Spectres to steal the ships on Lothal . Meanwhile Ezra , Kanan , and Chopper managed to find Prisoner X - 10 on Lothal and learned that he was Governor Azadi , a friend of Ezra ' s parents . From Azadi , Ezra learned about the deaths of his parents and was able to make peace with his past . Reuniting on Lothal , the Spectres then joined forces with Princess Leia and Azadi to steal the Hammerhead corvettes from an Imperial depot on Lothal . In 2 BBY , before Grand Admiral Thrawn attacked Atollon , Ezra mentioned the assault on Garel as they received the warning about the Imperial fleet leaving Lothal . Behind the scenes . The battle on Garel first appeared in the " Star Wars Rebels " episode " Legacy " , which premiered on Disney XD on December 9 , 2015 .
