Occupation of Bespin

In 3 ABY, the Galactic Empire won the Battle of Hoth and forced the Rebel Alliance offworld. The Imperial Fleet's Supreme Commander, Darth Vader,pursued the Rebel leaders, in particular his son, Jedi Luke Skywalker. He hired the bounty hunter Boba Fett and other mercenaries to find the Millennium Falcon, the starship carrying the Rebel leaders. Fett spotted the Falcon fleeing the Hoth Imperial blockade and deduced its destination, Cloud City on the gas giant Bespin. Lord Vader arrived before the Millennium Falcon and forged an initial agreement between himself and the Baron Administrator, Lando Calrissian. Calrissian would aid Vader in capturing the Rebels, in exchange for the continued freedom of his colony.

The Millennium Falcon entered and landed in Cloud City, piloted by Han Solo and the Wookiee Chewbacca. They also had Leia Organa and the protocol droid C-3PO on board. Its crew was greeted as welcomed guests by the Baron Administrator, who gave an especially warm welcome to his old friend, Han Solo (although not before initially coming across as hostile due to a past stunt that Solo pulled). They were given accommodation in which to dwell while their ship was being repaired. After landing, C-3PO wandered off and was shot by a member of Gamma Squad, dismantling him. C-3PO's remains were later sent to the recycling area of Cloud City, although they were intercepted by Chewbacca, who retrieved the parts. After a while, Calrissian invited them to a dinner arrangement, which turned out to be a trap, set by Darth Vader. Solo, upon discovering Vader in the dining room, attempted to shoot the Dark Lord with his blaster, only for Vader to effortlessly absorb the bolts with his right hand, and telekinetically pull the smuggler's blaster away from him with his left. Stormtroopers surrounded the Rebels, ensuring their capture.

Later, Lieutenant Sheckil informed Lord Vader of C-3PO's destruction, and the cyborg visited the wreckage, remembering back when he had created the protocol droid as a young boy, and ordered the droid to be returned to Chewbacca while he prepared to interrogate Solo. He wanted to use Organa, Solo, and Chewbacca's capture as a lure to capture his primary objective, Skywalker. Indeed, Han Solo was tortured but not asked questions in order to trigger a response from Luke through the Force, sending him to rescue his friends. The Imperials disabled the repaired Millennium Falcon's hyperdrive to prevent its escape.

Vader had Solo frozen in carbonite, to test to see if the freezing methods would effectively work on Skywalker. This was an important part of his plan; he would either take his frozen son to the Emperor, or change plans and turn him into his own apprentice for use against his master. He had Solo shipped to the gangster Jabba the Hutt by way of Boba Fett, who claimed Solo's bounty.

This was a violation of his agreement with Calrissian, something Vader casually dismissed as an alteration of the deal. Shortly afterward, Vader's hopes were realized as Skywalker's ship was detected heading towards the city. As Vader left to prepare for his confrontation with the young Rebel, he gave clear instructions to Calrissian to keep Leia and Chewbacca on the planet, violating the agreement again.

Meanwhile, Skywalker had landed in the city and caught a glimpse of his friends being taken away by Imperial troops led by Lieutenant Sheckil. He was caught in a brief firefight with Boba Fett, who was protecting his cargo. Though Princess Leia managed to shout a warning to him, Commander Skywalker continued further into the city, ending up in a carbonite processing chamber where he faced Lord Vader in lightsaber combat.

Realizing that the situation was deteriorating, Lando Calrissian arranged for the Bespin Wing Guard members Helder Spinoza, Corman Jeihn, Pedar Solardo, Gir Endac, and Razell Tameron to free Organa and Chewbacca from their Imperial escorts, resulting in Sheckil and his Imperial unit's arrest in the process. However, Organa and Chewbacca did not trust him due to his earlier betrayal of Solo, the latter also nearly killing him via strangulation, although Calrissian ultimately managed to relay that they still had a chance to save Solo from Boba Fett, causing them to decide to aid him and pursue the bounty hunter. While escaping, Calrissian alerted the populace to the Empire's takeover of the city and advised that they evacuate the city before more Imperials arrived. Calrissian's announcement likewise caused a mass-panic that aided the group in slipping past most Imperial patrols. Organa ordered the astromech droid R2-D2 to assist in opening doors for her to reach the Millennium Falcon.

R2-D2 then tried to access sockets to Cloud City's main computer to access the doors, although thanks to C-3PO's poor advice, the astromech droid inadvertently electrocuted itself at one of the sealed doors by accessing a power outlet instead. While pursuing Boba Fett, the bounty hunter returned fire and taunted about how Solo was now his and no one would take his bounty. Just after accessing the landing pad for the Millennium Falcon, R2 also uncovered information from Cloud City's main computer that indicated that, although the hyperdrive was indeed fixed, it had also been deactivated by the Imperials, and attempted to warn them. The Falcon then gave chase to Slave I, disabling its shields in a vain effort to recover Solo.

The duel between Vader and Skywalker continued out onto an enormous wind tunnel, where Luke would lose his right hand to Vader's lightsaber and have his true parentage revealed. Even as Vader beckoned him to join his side and thus help end the Galactic Civil War, Luke stood defiant and chose to take his own life by falling from the platform they were on. As he plummeted towards the ground, he was sucked into one of the gas exhaust pipes and emerged below the city, grabbing onto a weather-vane.

In a final attempt at survival, Skywalker contacted Princess Leia through the Force, who, having escaped in the Falcon, now ordered the ship around to look for him. As they were rescuing Skywalker and taking off again, four members of the TIE Fighter squadron, Obsidian Squadron, appeared off the tarmac and gave chase. The Millennium Falcon fired back and shot down several TIEs. The fighters had already been deployed for patrol duty even before the formal takeover of the planet.

Having escaped the planet, the Falcon now headed out into space, where it encountered Lord Vader's flagship, the Executor ,under the command of Admiral Piett in orbit. Attempting to flee into hyperspace, the crew found that Imperial technicians repaired their hyperdrive, but disabled it in the event of their escaping the city. As the Executor prepared to take the ship by tractor beam, R2-D2 managed to activate the hyperdrive, having been warned about the deactivation earlier by Cloud City's computer, and the Millennium Falcon escaped once again.

An Imperial strike force was formed to take over the city. The TIE/D Defenders and TIE Interdictors cleared a landing zone in a break in the city's anti-air defenses and fighter cover. The strike force, a mixed force of stormtroopers with repeaters, four dewback troopers, five ASP-7 labor droids, deployed from the seven landing craft and spread out. The landing craft also deployed four All Terrain Scout Transports, six All Terrain Personal Transports, four Phase II dark troopers, four Imperial Thermal Detonator Troopers, and two Heavy Imperial Missile Launcher Troopers. The city had six Gravity Control Centers spread throughout, and the Rebels were planning on disabling them to scuttle the city and prevent its takeover. After landing, the strike force engaged T3-B heavy attack tanks sent their way and beat back Lando's Commandos.

The Imperial strike force's bombers attacked a nearby tibanna gas platform and destroyed its storehouses to acquire additional resources. The strike force's labor droids established a base, and the force fought through the Rebel and the Bespin Security Force defenders, destroying storehouses in the process to acquire more resources. Walls prevented the strike force from accessing parts of the city; the strike force used their landing craft to reach those areas.

The strike force reached the Gravity Control Centers to prevent their destruction. The Imperials also destroyed the Bespin Government Center and built an Imperial Palace in its place to cement their occupation.

Skywalker, Organa, Chewbacca, Calrissian, and the droids returned to the Alliance Fleet, where Skywalker received a prosthetic hand. With the Rebels defeated, the Empire took control of the city and the tibanna gas mines. Cloud City and its remaining population had to endure the occupation of an Imperial garrison under the command of Hugo Treece for many months, until the Liberation of Bespin, which would see the Empire driven out of the colony. Nonetheless, there were some minor skirmishes prior to its liberation, such as a raid by the Rebel Alliance on the tibanna gas platforms shortly before the Battle of Endor, and an internal rebellion by the Ugnaught population caused by Treece unofficially turning Cloud City into a slave camp due to his embezzling funds.

The occupation of Bespin first appeared with the release of Star Wars: Episode V The Empire Strikes Back.

The 2001 video game Star Wars: Galactic Battlegrounds presents the player with the opportunity to play through the occupation during the Darth Vader campaign. The campaign was also included in the game's 2002 expansion pack, Clone Campaigns. The player is tasked with establishing a base and securing the Gravity Control Centers. The player has the option of building additional units, and may also attack a mining platform for its resources. Half of the six Gravity Control Centers must survive and the player must destroy the Bespin Government Center to complete the mission.

In Star Wars: Rogue Squadron III: Rebel Strike, the Occupation of Bespin was a bonus mission called "Escape from Bespin." It branched off from one of the main missions in Wedge's campaign, Guns of Dubrillion, implying that the event was concurrent with the Battle of Dubrillion.

The battle also appeared in LEGO form in two missions in the 2006 video game adaptation of the Original trilogy, LEGO Star Wars II: The Original Trilogy. The missions are also included in its 2007 compilation re-release.
