The conflict known as the Tocan system disaster involved combat between the forces of the Alliance to Restore the Republic and the Galactic Empire. Despite the survival and subsequent withdrawal of several Alliance starfighters to Ghorman for recovery, the Tierfon Sector Fleet of the Empire achieved victory. These Alliance survivors were later deployed during Operation Cobolt.
