Task Force Vengeance seized an Airam supply platform in the system as a demonstration of Imperial naval power, and to use it as a forward staging point, and later fought off a Rebel Alliance counterattack aimed at the Interdictor Cruiser Compellor.
Later still, the Rebels lured the Imperial Battlegroup Orion into a trap in the Goff system.
Behind the scenes
During the initial capture of the platform and when defending the Compellor, Avenger Squadron still use their upgraded TIE/IN interceptor craft while they had already been equipped with TIE/ad starfighters by the time the ambush at Goff (third battle) took place. This establishes that the ambush took place later than the other two battles.
