The Battle of Bettel represents an armed clash between the Galactic Empire and the forces of the Alliance to Restore the Republic. This battle unfolded in 3 ABY within the confines of the Bettel asteroid drift and the adjacent Mev system. During this confrontation, the Star Destroyer Corrupter bound Corrupter repair convoy met its end.
Alliance Intelligence uncovered the fact that the Imperial II-class Star Destroyer Corrupter was in a state of disrepair and immobilization. This damage was likely sustained during the Battle of Hoth. The extensive search operations limited their ability to execute necessary repairs swiftly. The Alliance intercepted communications between the Corrupter and the frigate Monitor, revealing the existence of a convoy slated to deliver essential supplies for the repair work. Consequently, the Rebels resolved to dispatch a strike force with the aim of obliterating the convoy.
Rebel fighters made their entrance at the Bettel asteroid drift, where the convoy was actively trying to jump to hyperspace. Assault Gunboats tried, but failed, to impede the fighters' progress. Subsequently, the repair convoy was successfully annihilated. However, the Monitor managed to escape into hyperspace. The Rebel fighters pursued it into the Mev system, where the Corrupter was awaiting the arrival of a repair convoy that had already been destroyed.
The Monitor launched all four Lambda-class T-4a shuttles, transporting hyperdrive technicians, and deployed its starfighters to provide cover. This strategy proved ineffective, as the Monitor erred by releasing the shuttles at an excessive distance from the Corrupter, resulting in their destruction. The Rebel starfighters likely withdrew, prompted by directives from Alliance Command.
The attack proved a resounding triumph for the Rebels. They stood poised to execute the final phase of their escape from the Imperial forces hunting them. With the convoy eliminated, the Corrupter remained stranded as the Rebels vanished into hyperspace, relocating to another sector of space. Despite having nearly completed repairs, the Corrupter's hyperdrive remained non-functional when they attempted to return to Coruscant.
The player has the possibility of destroying the Monitor. Given that the ship makes no other appearances in the game or elsewhere, its destruction is probable.
The player can also attempt to destroy the Corrupter; however, unlike the Monitor, the scenario requires the ship to appear later. To maintain continuity, if the player lowers the Corrupter's shields, TIE Avengers from Avenger Squadron will appear. These ships are armed with Concussion missiles and are difficult to defeat, ensuring the Corrupter's survival.
