The Eight-Hour Invasion of Dubrillion was a battle of the Cold War between the Galactic Republic and reconstituted Sith Empire. It was a surprise attack from Imperial Army against the relatively unprotected planet of Dubrillion. However the few Republic troops there repelled the Sith invasion force with minimal reinforcements for eight hours. After this time, the arrival of a massive amount of Republic soldiers forced the Imperial forces to withdraw.
