Raid on Bespin The Raid on Bespin was a minor engagement by the Alliance to Restore the Republic against the Imperial - occupied tibanna gas mining facility Cloud City . The Rebel ' s Rogue Squadron engaged Imperial TIE fighters and siege balloons to secure the tibanna gas platform s and allow transports to move in and take the gas . The squadron then moved into Cloud City to secure the remaining platforms . The Imperials launched a reprisal strike with TIE bombers , but the Rogues shot them all down . Prelude . In 3 ABY , the Galactic Empire pressured the Baron Administrator of Cloud City , Lando Calrissian , into giving them Han Solo and his friends with the threat of an occupation of Cloud City . Shortly thereafter , the Empire reneged on its half of the bargain and conquered the planet . Some time after , the Rebel Alliance , which was fighting the Empire , received intelligence about a new , powerful superweapon , the Death Star II battlestation . The Alliance therefore planned an attack against the station in 4 ABY . As part of the lead - up , the Alliance launched a raid against Bespin to capture valuable tibanna gas for the Alliance Fleet . Rogue Squadron was assigned to the raid some time after their Mission to Prefsbelt IV . Raid . However , the Imperials has had anticipated the Rebel ' s raid , and planted seven siege balloons on guard near a series of six tibanna gas platform s . The balloons were also ordered to target and destroy the platforms , preferring it to the alternative of letting the Rebels secure the tibanna gas . Rogue Squadron , under the command of Commander Wedge Antilles , was assigned to the mission to raid Bespin by securing the platforms and escorting three Rebel Transports while they were in route to Cloud City itself . Rogue Squadron first targeted the siege balloons in order to ensure that they didn ' t blow up the platforms . By the time the Rebels arrived at the second tibanna gas platform , Rogue Leader Wedge Antilles shot down an Imperial tanker , and uncovered some homing concussion missile s to which he procured , although it came at the cost of most of the tibanna gas containers on the platform . Afterward , Rogue Squadron had to deal with several squadrons of TIE / LN starfighter s and TIE interceptors that were proceeding to target both the platforms and the transports . Antilles and the Rogues engaged and destroyed the Imperial starfighters . The three transports then docked with the platforms as Antilles ordered the Rogues to form up . A Rogue pilot spotted three main power generators in Cloud City on his targeting computer and suggested destroying them to weaken the turbolaser defenses . Antilles ordered them to destroy the generators and wished them luck . After destroying the generators , Antilles reported the objective ' s success and ordered the squadron to save the gas platforms . Rogue Squadron commenced with mopping up operations by destroying more siege balloons near the final two tibanna gas platforms , as well as destroying a newly - dispatched TIE bomber squadron . Aftermath . With the Imperial presence threatening the gas platforms removed , Antilles congratulated the Rogues and informed the transports they could move in . Soon after , the Alliance Fleet left for the Battle of Endor , where they survived Emperor Palpatine ' s trap and destroyed the Death Star II superweapon / battlestation . The loss of the station resulted in both the Emperor ' s and Darth Vader ' s death , and the eventual fragmentation of the Empire . Behind the scenes .
