Operation Ringbreaker was a strike conducted by the Rebel Alliance's Sixty-First Mobile Infantry, often known as "Twilight Company," on several worlds held by the Galactic Empire. The eventual intent of the campaign was to disable the heart of the Empire's ship-building operations, the Kuat Drive Yards. Eventually, however, Twilight Company abandoned the campaign in favor of assisting the Sullustan people in the aftermath of the Siege of Inyusu Tor.
