The Battle of Nomlis III was a confrontation during 3 ABY between the forces of the Galactic Empire and the Alliance to Restore the Republic. The outcome of this battle was the annihilation of the Bretie Facility.
In 3 ABY, the Mon Calamari Star Cruiser known as the Liberty was on a mission to investigate Imperial activities related to the recently discovered TIE Experimental Project. The Empire had been deploying a new series of TIE starfighters, utilizing them to attack and harass civilian convoys. Due to the suspicion that the Empire planned to use these fighters against the Alliance, disrupting this project became a very important goal for the Alliance.
During their investigative efforts, the Rebels learned that the starfighters were being researched and developed at an installation referred to as the Bretie Facility, which orbited Nomlis III within the Kurdin system. It was determined that the facility's databases contained comprehensive information on the starfighters and their developers, which led the Rebels to launch an operation with the goal of raiding the facility and acquiring all pertinent data related to the project.
Upon their arrival in the space surrounding Nomlis III, Red Squadron, consisting of four X-wings and led by Ace Azzameen, initiated an assault on the facility's standard and large gun emplacements. They then proceeded to obliterate the station's supplies and the escaping transports, including two Xiytiar-class transports. Simultaneously, Storm Unit utilized an assault transport to board the Bretie Facility, covered by a pair of A-wings. While the Rebel fighters continued to fend off TIE Experimental M1s and M3s, Storm Unit fought their way to the central computer, downloaded all data related to the TIE Experimental Project, set explosives, and quickly escaped. The resulting explosion completely destroyed the Bretie Facility, dealing a significant setback to the Empire's latest plans.
Using the information acquired from the now-destroyed Bretie Facility, the Rebels were successful in discovering the location of platform Obsidian—the central location of the TIE Experimental Project. In response to the theft of valuable data, the Empire launched an attack on the cruiser Liberty, where the Rebel strike team had just returned.
