Battle of Gall The Battle of Gall was a conflict initiated by members of the Rebel Alliance in 3 . 5 ABY , during the search for Boba Fett and his carbon - frozen prisoner , Han Solo . Background . On Ord Mantell , Dash Rendar tracked down IG - 88D in a scrap yard on the planet to interrogate him about the whereabouts of Fett . IG - 88 gave him information , but then fired on Rendar , only to be destroyed . When Lando Calrissian learned from Dash Rendar that Fett had been spotted on Gall , he informed his friends , Luke Skywalker and Leia Organa . They departed for Gall , where they met up with Skywalker ' s Rogue Squadron and Rendar himself . Fett , they learned , had stopped off at Gall for repairs to his ship , the " Slave I " , and now seemed the perfect opportunity to ambush the bounty hunter and free his captive . The battle . Battle plan . However , this rescue mission was confounded by the presence of an Imperial Enclave , with two Star Destroyers on patrol . Luke concocted a simple , yet risky plan ; utilizing the combat skills of the Rogues to keep the Enclaves ' fighter complement at bay , while counting on the piloting ability of Dash to lead Lando and Leia to Fett ' s ship . Despite the obvious danger of thirteen X - wings taking on a hundred and forty four TIE fighters , it was , as Luke pointed out , the only plan they had . Rescue attempt . The rescue attempt was launched , with the Rogues flying in on a strafing run against the dayside Star Destroyer . Only twenty fighters were scrambled to meet the threat – the pilots no doubt thinking it was only a drill – though an additional squadron was soon launched . The Rogues did an impressive job of keeping the fighters away from the Grand Trench – where Rendar ' s " Outrider " was leading the " Millennium Falcon " towards the spaceport city – only losing one pilot when Will Scotian was forced to return to base after sustaining damage to his craft . The Rogues ' luck could not last , however . Another wave of TIEs approached – among them several TIE Interceptors , and Rogue Five was destroyed in the battle . Worse , the second Star Destroyer joined the battle , launching its own fighters into the fray . Fortunately , the " Falcon " reached the spaceport after a harrowing run through the Grand Trench , though Dash decided to leave the Rebels to face Fett alone — as he later remarked , he was paid only to guide , not shoot . And with a dozen TIE fighters on their tail , the crew of the " Falcon " was in dire need of help . Into the Enclave . Leaving the battle in space , Dash landed his ship into a remote valley on the planet ' s surface . With Leebo guarding the ship , he moved on through the canyon , killing stormtroopers and Imperial commando s as he made his way into the Enclave . Once inside , he hacked into the control computer and found out Fett ' s location – a docking bay in the spaceport across the canyon . Stealing a jetpack , he began to fly across the canyon and make his way up to the hangars . Stealing an Imperial patrol skiff for part of the trip , Dash eventually flew his way up to the spaceport with his jetpack , immediately facing an AT - ST assigned to sentry duty . He destroyed it , and the explosion made a wall protecting vent controls malfunction and open . Opening the vent shafts , he crawled through them , deeper into the inside - mountain installation . He ripped through more stormtroopers and commandos , briefly stealing another skiff before making his way to the top of the tower that served as the " Slave I " ' s docking bay . There he engaged Fett in an air duel . With his jetpack blasted by Rendar , Fett flew out of control and crashed right into the " Slave I " . Unwilling to lose the fight and his hard - fought quarry , he quickly began to attack Rendar with the ship ' s weapons systems . Yet even with the " Slave I " ' s firepower , he was ultimately bested by Rendar , and the " Slave " itself was disabled . However , an Imperial transport quickly picked up Fett and Han Solo ' s carbonite block , and headed towards Tatooine to deliver them to Jabba the Hutt . Assassination attempt . Over the Enclave base , the Rogues , like Dash , decided to cut and run , preparing for a mock hyperspace jump to fool their pursuers into believing they had left the system . Plotting a course towards their base on the moon of Kile , the Rogues were shocked to see Wes Janson ' s X - wing firing on Luke . The frantic Wes realized his astromech droid had taken control of his ship and with no way to stop the droid , Luke was forced to disable his fellow pilot ' s fighter , before towing him back to base . There , in a disturbing development , Luke found that the astro - droid had been programmed to kill him . Retreat . Meanwhile , the rescue mission was over — and it had not been a success . Forced to evade incoming TIE fighters , the Rebels had been unable to prevent Fett ' s escape , and without the Rogues on hand , he was able to flee into hyperspace with the frozen Han . Dejected , the crew returned to base , where the matter of Luke ' s attempted assassination led to an even bigger conflict .
