Gandolo IV Gandolo IV was a barren , rocky moon in the Gandolo system of the Lahara sector , in the Outer Rim Territories . Shortly before 1 BBY , a group of several dozen fugitive Wookiee slaves , including the famous Chewbacca , attempted to establish a safe colony on the moon but was discovered by the Trandoshan bounty hunter Bossk . Paid in advance by the Imperial sector governor , Bossk and a team of hunters landed on Gandolo IV to capture the renegade Wookiees . The hunt proved particularly opportunistic for Bossk , who finally got a chance to capture Chewbacca after the Wookiee had continuously eluded him for some time . Before the Trandoshan could secure his quarry , however , Chewbacca ' s smuggling partner , Han Solo , returned to Gandolo IV from business elsewhere to find the Wookiees detained . Careful not to harm Chewbacca and the other Wookiees , Solo strafed the camp in the " Millennium Falcon " and proceeded to land his ship directly on top of Bossk ' s own ship , crushing it . The Wookiees overpowered Bossk ' s group in the mayhem . Although the Wookiees were forced to abandon their colonization effort , Solo and Chewbacca promised to help them set up a new colony elsewhere . The incident turned into an utter humiliation for Bossk , whom Solo and Chewbacca had left trapped in his ruined ship , rather than killing him . Bossk , determined to avenge himself for the embarrassment , would be painfully reminded of the Gandolo IV fiasco on occasion for the next twenty - five years . Description . Gandolo IV was a barren , rocky moon located in the distant Lahara sector ' s Gandolo system , within the north - eastern quadrant of the Outer Rim Territories . Its surface pockmarked with large craters , Gandolo IV appeared gray and lifeless from space . History . The Wookiee colony . Sometime shortly prior to 1 BBY , a group of several dozen renegade Wookiee colonists led by Chewbacca set up a safe retreat on the remote , barren moon Gandolo IV . When news of the Wookiee colony ' s establishment reached Bossk , a successful Trandoshan bounty hunter , he jumped at the opportunity to hunt down the refugees . Bossk harbored a vile hatred of Wookiees , with whom his species shared the Kashyyyk system , as well a blood feud after the Galactic Empire declared Wookiees to be slaves at the behest of a Trandoshan dignitary during the early Imperial Period . Bossk was among the Trandoshans vowing to help bring all fugitive Wookiee slaves to Imperial justice . Despite his successes at hunting Wookiees , he most desired to capture the elusive Chewbacca , who , along with his Human smuggling partner , Han Solo , had earned quite a reputation among the criminal underworld . Chewbacca refused to present himself to his Trandoshan pursuer , but Bossk ' s opportunity came at Gandolo IV . After the bounty hunter first visited the Lahara sector ' s Imperial governor in order to be paid in advance for the bounty on the Wookiee colonists , Bossk and a handful of fellow hirelings armed themselves for the trip to Gandolo IV , where they found their quarry . A group of poorly armed Wookiees was setting up a small outpost on the barren moon with the assistance of Chewbacca himself . Bossk ' s group , greatly outnumbering their prey , easily surrounded and captured the camp , catching the Wookiees almost completely by surprise . With their captives in binders , the hunters were on the verge of skinning the Wookiees when Han Solo arrived on the scene . Solo had previously dropped Chewbacca off on Gandolo IV before proceeding to a nearby star system to visit an old girlfriend . The Corellian , piloting the " Millennium Falcon " , returned only to detect the bounty hunters ' ship from low orbit , and he knew something was wrong . Solo dropped in on the camp unannounced , strafing low over the confused bounty hunters with a hail of laser fire from the " Millennium Falcon " . Knowing he couldn ' t directly attack the hunters for risk of hitting the bound Wookiees , Solo was careful to shoot only the ground , which sent Bossk and his crew scattering for their own ship . Although the Trandoshan ' s craft was larger and better armed than his own , Solo had already outwitted them . As soon as Bossk had raised his boarding ramp , Solo lowered his landing gear and brought the " Millennium Falcon " directly down upon the bounty hunter ' s ship . The additional weight of Solo ' s freighter buckled the landing struts of Bossk ' s ship in a collapsed heap of explosions and a cloud of shot hydraulic fluids . When Solo lifted the " Millennium Falcon " off the ruined ship , it rolled over onto its side , a wrecked heap . Bossk and his team tried desperately to open the emergency hatches of the ship , to no avail . In the confusion , Chewbacca and the Wookiees escaped their captors . They broke free of their binders , dispatched the two bounty hunters guarding them , and proceeded to neutralize the rest of the group before disabling the drive and weapons systems of Bossk ' s ship . Solo and Chewbacca left Gandolo IV behind , promising to help the rest of the Wookiees find a new place to establish a safe colony . They refused to kill Bossk , however , leaving him and the bounty hunters trapped in their damaged ship . Only Bossk ' s natural regenerative ability to regrow lost limbs saved him from Solo ' s ambush . It took he and his companions several days to finally work their way out of their crushed ship with a few blasters and hand torch es . A week later , they were rescued from Gandolo IV ' s barren surface by a small out - world hauler transporting nerf manure . The Gandolo IV incident proved a bitter humiliation for Bossk , and a rare setback . He had lost his ship , his Imperial bounty on the fugitive Wookiee slaves , but more importantly , he had lost his chance at capturing Chewbacca . The embarrassment that Solo had caused him also inspired in the Trandoshan a strong desire to one day seek vengeance on the Corellian smuggler . Bossk ' s continued humiliation . Bossk ' s humiliation at Gandolo IV would stay with him for years , and he yearned for retribution . When Darth Vader summoned an elite group of bounty hunters , including Bossk , to his Super Star Destroyer , the " Executor " , in the wake of the Battle of Hoth in 3 ABY to capture Han Solo and his Rebel companions , the Trandoshan formed an unorthodox partnership with fellow bounty hunters Tinian I ' att and the Wookiee Chenlambec . The trio agreed on an uneasy alliance to capture Solo and Chewbacca — in reality a ruse by I ' att and Chenlambec to capture Bossk — by tracking them to the planet Lomabu III . During their negotiations , I ' att surreptitiously mocked Bossk by casually mentioning to him that she and Chenlambec and heard something about the Gandolo IV incident , which irked the Trandoshan . In fact , Chenlambec ' s own brother had been among Gandolo IV ' s Wookiee colonists , standing next to Chewbacca as they watched their situation turn from disaster to success , and then utter hilarity at the expense of Bossk ' s group . I ' att ' s and Chenlambec ' s cover story involved telling Bossk of a safe colony a group of Wookiees was attempting to set up on Lomabu III , not unlike that of Gandolo IV . However , the situation on Lomabu III was quite the opposite . The planet was actually the site of an Imperial prison camp containing several hundred Wookiees , which would correspond closely to the former layout of Gandolo IV ' s outpost , as Chenlambec related to I ' att . Although Bossk hoped to manipulate the situation by tricking Chenlambec into wiping out his own kin in the purported Wookiee colony , thus avenging himself for Gandolo IV , I ' att and Chenlambec double - crossed him and rescued the Wookiee prisoners . Gandolo IV was still a sore subject for Bossk many years later . In 25 ABY , Bossk once more encountered Solo on the " Jubilee Wheel " , a space station orbiting Ord Mantell . The Trandoshan , joyful at Chewbacca ' s recent death at Sernpidal , mocked Solo for his loss , citing the anger he still felt for the humiliation he was dealt on Gandolo IV . Solo gloated in return , remembering well how he landed the " Millennium Falcon " on top of Bossk ' s ship , crushing it , much to Bossk ' s mortification . Locations . Shortly before 1 BBY , several dozen fugitive Wookiee slaves attempted to establish a safe colony on Gandolo IV , free from the galaxy ' s Imperial - motivated persecutions . After Bossk and his bounty hunting entourage discovered and attacked the colony , the Wookiees abandoned their efforts on Gandolo IV with Han Solo ' s and Chewbacca ' s promise that they would help the refugees find a new location for safe haven . Behind the scenes . Notable appearances . The moon Gandolo IV was created for the 1989 first edition of the West End Games sourcebook " " , written by Michael Stern . The moon serves as the locale where the bounty hunter Bossk first encountered the infamous outlaws Han Solo and Chewbacca , providing a backstory for the Trandoshan bounty hunter seen in the employ of Darth Vader in . The incident on Gandolo IV establishes Bossk ' s motivation for hunting Solo and Chewbacca in the film . The 1995 " The Essential Guide to Characters " recounted the Gandolo IV tale in Bossk ' s character entry , expounding on and establishing several new minor additions to the story . The Gandolo IV incident would be referenced by author Kathy Tyers in the short story " " , appearing in the 1996 anthology book " Tales of the Bounty Hunters " . She would use the details of the story from " Galaxy Guide 3 " to supplement her own , in which her protagonists use Bossk ' s desire to redeem himself for his failure at Gandolo IV to trick and capture him . The incident was likewise referenced in James Luceno ' s 2000 novel " " , as part of " " series of stories , in which Solo and Bossk reencounter one another years later , still remembering quite well what had happened . Gandolo IV also appears as one of 200 playable worlds in the 1998 PC game , which provided the planet ' s only canon ical visual depiction to date , an illustration as a rocky moon in accordance with Gandolo IV ' s original physical description from " Galaxy Guide 3 " in 1989 . The image used for Gandolo IV , however , is replicated in use with sixteen other planets of similar barren composition in the game . Inconsistencies . " Star Wars : Rebellion " and " " both place Gandolo IV in the Moddell sector of the Outer Rim , relatively close to the Forest Moon of Endor . This geographical placement has since been overridden by the 2009 release of " The Essential Atlas " and its related online material on StarWars . com . Additionally , the " Star Wars : Rebellion " in - game encyclopedia seemingly refers to the Gandolo IV Wookiee colony as existing concurrently with the chronological start time of the game , which begins in 0 ABY , the day after the Battle of Yavin . This time frame has since been overridden by the 2002 " The New Essential Guide to Characters " , which places the Gandolo IV incident prior to the events taking place in the comic " " , prior to the Battle of Yavin . The 2008 " The Complete Star Wars Encyclopedia " explains in the " Gandolo IV " entry that Han Solo lands the " Millennium Falcon " on top of an Imperial troopship during the incident with Bossk , killing all aboard . This is a significant contradiction from all previous sources describing the incident , in which Bossk and his crew are aboard his own ship , rather than an Imperial troopship , as it is crushed , only to dig themselves out later , still alive .
