Rescue from the Dargon The rescue from the " Dargon " was an operation conducted by the Alliance to Restore the Republic in which an attempt was made to rescue Rebel prisoners on the " Dreadnaught " - class prison ship " Dargon " as it traveled through realspace to its hyperspace jump point at Darg - 3 . Prelude . After the recent raid of the Mobquet medium transport Suprosa and theft of a supercomputer . Darth Vader was sent to investigate the circumstances behind the attack . Imperial command had captured high ranking Rebel and Bothan prisoners , that were trying to leave Coruscant , and brought them to the Dreadnaught " Dargon " which was to rendezvous with the Imperial - class Star Destroyer " Garrett " . Imperial intelligence suspected an attack would be made by the Alliance , either to rescue their comrades or , failing that , destroy the dreadnaught . The Battle . First Stage . Maarek Stele was assigned to relieve the previous TIE Advance and escort the Dreadnaught . Soon afterwards , multiple Rebel starfighters including A - wings , B - wings , X - wings and Y - wings from Red Squadron arrived . As Stele engaged the fighters two Corellian Corvettes named " Keeper " arrived carrying Explosives , indicating that the Rebels were willing to destroy the Dreadnaught rather than disable and rescue their own . Stele helped the Dargon fight of the corvettes and destroy them , while a similar number of starfighters from Gold Squadron arrived to comlpicate things . A modified corvette " Hut ' to " arrived to block the path of the " Dargon " , followed by Blue Squadron , but despite fighters flying around was soon destroyed by Stele . Soon the Mon Calamari Cruiser Columbia arrived but by then the " Dargon " escaped into Hyperspace . Second Stage . Before the " Dargon " could reach the " Garrett " it then suffered engine failure and was about 23 Kilometers away . Supsecting sabotage and Vader being impatient sent an assault transport " Sigma 1 " to board and bring the prisoners to him for interrogation . When Stele was launched to oversee the operation , " Sigma 1 " had already acquired the prisoners under escort from TIE Fighters and was on its way to the " Garrett " when a modified frigate " Bay Point " arrived and launched A - wings and Y - wings to intercept the transfer . Although able to eliminate the TIE Fighters , they were thwarted once again as Maarek Stele and his wingmen engaged and destroyed the Rebel fighters , allowing the transport to be brought to the " Garrett " Aftermath . While Vader interrogated the prisoners , Stele was debriefed about the capture of the " Suprosa " . Vader , wanting as much information as possible , decided to attack the Bothan trade routes to gather more information about the freighter ' s location . Behind the scenes . This battle first appears in the 1994 PC Game " Star Wars : TIE Fighter " in the expansion pack " Enemies of the Empire " which was released in 1995 . It appears in the twelve " Battle " called Prelude to Endor as the first mission for the first phase and the second mission for the second phase . This article assumes " Medium " difficulty . If the player tries " Hard " Difficulty then a similar number of fighters from Grey Squadron is added along with multiple A - wings from Yellow Squadron for the first mission . While in the second mission there are more A - wings as well to contend with . However , the first stage also appears in the computer game " " , which was released April 30 th 1997 and is one of the missions on . In this case , players can participate in the mission " Rescue from Imperial Prison Ship Dargon " on either the Rebel or the Imperial side — both sides have conflicting mission objectives — and victory is not essential to access the next set of missions , like all the other missions on Operation : Quick Strike , the battle itself is considered canon but the canon outcome of the battle is unknown . The mission features Rogue Squadron which would engage the TIE Avengers and Assault Gunboats escorting the prison ship " Dargon " , while Red Squadron covered Gold Squadron as the Y - wings disabled the Imperial " Dreadnaught " . After the " Dargon " is disabled , the Calamari Cruiser " Columbia " would arrive nearby , to launch Typhoon Group , a trio of " Gamma " - class ATR - 6 assault transports , in a bid to board and capture the " Dargon " . Some time later , the " Victory " - class Star Destroyer " Callisto " would arrive to rendezvous with the " Dargon " , along with an Imperial ATR - 6 transport called XP - 1 to carry a team intending to repair the damage done to the " Dargon " . It is virtually certain , given the overwhelming numbers of Y - wing starfighters and the mag pulse warheads carried by Rogue Squadron , that the " Dargon " will be disabled ; whether it is then captured by Alliance Special Forces or recovered by the Imperial repair crew aboard " XP - 1 " depends largely on player actions and is uncertain . This article is assuming " Star Wars : TIE Fighter " as the official Legends canon story .
