The conflict known as the Battle of Udnil II unfolded in space between the Alliance to Restore the Republic and the forces of the Galactic Empire. This clash occurred when Rebel pilots launched a daring strike against the Tormentor, an Imperial-class Star Destroyer. The Tormentor was in the process of meeting with a supply convoy within the Udnil system, specifically in proximity to the second planet.
When the Tormentor was receiving a shipment of ten Class-A cargo containers and linking up with Munro Group, a small convoy of BFF-1 bulk freighters, a Rebel strike force materialized from hyperspace, likely within or near the gravity well of Udnil II. This force consisted of Gold Squadron, piloting Y-wing attack starfighters, and Red Squadron, flying X-wing superiority starfighters. As the Rebels initiated their bold assault, Munro Group promptly departed the system.
However, the Imperial-class warship possessed its own complement of starfighter defenses. A squadron of twelve TIE Avengers, then regarded as some of the most formidable fighters in the galaxy, was deployed to intercept the attacking Rebels. Their mission was to neutralize the threat before significant damage could be inflicted upon the Tormentor or its convoy, which included the Heavy Lifter Bellboy. To counter the swift and heavily armed TIEs, the Rebels may have requested assistance from Blue Squadron, known for their agile A-wing interceptors.
The computer game Star Wars: X-Wing vs. TIE Fighter includes the mission "Attack on Imperial-class Star Destroyer Tormentor," in which players can participate. Because each side has opposing goals, and winning isn't required to move on to the next set of missions, the battle is regarded as canon, but the canon result is unknown.
The ships mentioned in this article are those that appear in the battle Operation: Clean Sweep, utilizing the default vehicles assigned to the player.
