Battle of Dubrillion ( Galactic Civil War ) The Battle of Dubrillion was a battle during the mid - Galactic Civil War in 3 ABY . The battle , in the midst of the Dubrillion Ocean , was an attempt by the Galactic Empire to draw in and destroy a Rebel Alliance task force commanded by General Crix Madine and deal a crippling blow to the Alliance Special Forces . Prelude . The Rebel Alliance ' s original operation in the Dubrillion system had seemingly ended in failure . Wedge Antilles and his Y - wing squadrons had searched out the energy tunnels in the rings of Destrillion for the location of a tibanna gas mining facility which had discovered by Alliance Intelligence . When no facility was found and the Alliance fleet led by a MC80 Star Cruiser was about to leave the system , they regrouped and passed through Dubrillion ' s orbit in order to enter hyperspace . In truth , however , the Empire had planned the Rebels ' escape from the Dubrillion system , and when the Alliance fleet was caught in orbit and unable to exfiltrate , the Imperials sprung their trap . The battle . Bombing runs . The Alliance convoy was fired upon by an Imperial superlaser on Dubrillion ' s surface , which destroyed a GR - 75 medium transport . As the fleet was not able to do a safe jump into hyperspace , Wedge Antilles was ordered to lead a Y - wing squadron down to the planet . Wedge , when telling Rogue Squadron to descend down onto the planet , also referenced their earlier mission by telling them they weren ' t finished yet . By the time the squadron reached the superlaser , Madine informed them about three targeting relays the weapon used . Alliance squadrons swarmed into the Dubrillion superlaser facility , and came under attack by TIE / LN starfighter s and TIE / IN interceptors . Along with the fighters , Imperial submarine s emerged from the Dubrillion Ocean . Antilles led a bombing run on the three relay dishes for the superlaser , to reduce the accuracy of the main laser . He disabled the shields on the three relays with his ion cannon , then dropped proton bombs on each , destroying them . During the mission , Wedge Antilles spotted an object within the main superlaser dish . He sent his Y - wing down and managed to recover some advanced spread proton bomb s . While the accuracy of the superweapon was drastically reduced , the Alliance fleet was still taking casualties . In spite of the move to a safer orbit , the fleet was still pinned down . As the facility was also designed to withstand aerial assault , Antilles was ordered to go deep into the facility and shut it down , while his wingmen covered him from the air . Infiltration . In the midst of the battle , Antilles apprehended an All Terrain Scout Transport by causing an ion cannon blast to skim across its circuitry , not disabling the vehicle but causing it to temporarily malfunction . Upon hijacking it , General Madine reported that they had scientists who were familiar with the facility ' s layout , and patched one of them through . The scientist then explained that the only way to shut down the superlaser was to destroy its power sources , citing that the AT - ST he hijacked could get him further into the facility . He pressed forward , overtaking a fleeing stormtrooper squad and facing 10 more AT - STs and two stormtrooper - manned E - Webs . He was also strafed by TIE fighters . While navigating the docking area of the superlaser facility , Wedge made a brief detour , picking up some advanced concussion missile s . Antilles navigated the AT - ST through the superlaser facility , eventually reaching the elevator into the factory guarded by three AT - STs and stealthy missile droid s . The enemies opened fire on his walker , but he survived the travel down to the next level . The basement level was full of transportation rails . Avoiding explosive containers coming at him from the rails , one of which also destroyed an enemy AT - ST that was on patrol shortly after he arrived on the floor , and engaging more AT - STs , Wedge approached a large open area . While traversing to the next lift , he also exploited the explosive containers to destroy any enemy AT - STs in his path . There , he ditched his AT - ST in the factory in favor of an All Terrain Armored Transport with heavier firepower . With the AT - AT , Wedge was able to plow through the walkers and missile droids in his path , and he opened fire on the three turbines which were powering the superlaser , causing the facility to detonate . Making it back to his starfighter , Antilles and Rogue Squadron were able to escape before a chain reaction of several massive explosions pulverized the base . Aftermath . The plot to destroy the Alliance fleet had ended in failure , and with the loss of a whole superlaser facility , the Rebels dealt a massive blow to the Empire . Behind the scenes . This article was created based on a mission in the 2003 video game " . " As the bonus mission " Flight from Bespin " branches off from the Guns of Dubrillion , it is implied to be concurrent with the Occupation of Bespin and the Duel on Cloud City . The level was inspired by a rough sketch . In the commentary , the developers admitted that the result of the geometry was one of the best levels in the game . The suggested that the player destroy some of the AT - STs by blowing up the explosive tanks when they are directly near an AT - ST in the factory area .
