The decline and capture of Generis took place in the year 9 ABY. This event was a component of Grand Admiral Thrawn's campaign to reclaim the galaxy on behalf of the Galactic Empire.
Generis housed the Outer Rim Communications Center, a location of considerable strategic value. Therefore, Grand Admiral Thrawn personally orchestrated the attack, deploying a contingent of his newly created clone troopers. The Imperial forces, benefiting from both numerical advantage and tactical acumen, secured a win over the New Republic defenders, which included a distinguished Republic squadron led by Pash Cracken. The Imperials successfully captured the Communications Center with minimal damage and seized control of a significant portion of the sector fleet's supply caches.
During their withdrawal, the Republic troops managed to extract Travia Chan and her key personnel, while also preventing the Imperials from acquiring any functional starships. However, they still experienced a significant setback.
Notably, Imperial stormtrooper Grodin Tierce perished during the conflict.
