Batonn Batonn was a planet located in the Batonn sector of the galaxy ' s Outer Rim Territories . During the reign of the Galactic Empire , Admiral Thrawn was victorious in the Batonn insurgency , which led to the Emperor promoting him to Grand Admiral . Description . The planet Batonn was known to have one main continent and a smaller landmass called Scrim Island that lay 300 kilometer s to the west of the continent . One known city on Batonn ' s main island was Paeragosto City , which was the location of Governor Restos ' palace and was near the Creekpath Mining and Refining complex . Scrim Island was the location of an Imperial garrison and was protected by a deflector shield , shoreline defenses , four ion cannon s , and a turbolaser cannon . History . During the Imperial Era , Batonn exported doonium and other precious metals to the Galactic Empire , which used them to build the Imperial Navy and the Death Star . Arihnda Pryce ' s parent s Talmoor Pryce and Elainye Pryce relocated to Batonn ' s Creekpath Mining and Refining complex after losing control of Pryce Mining on Lothal . The planet was governed by the corrupt Governor Restos , who enforced order through the Batonn Defense Force . Eventually , resentment and grievances against Restos ' rule led to the emergence of an insurgent movement led by Nevil Cygni , who was known by his pseudonym " Nightswan " . The Batonn insurgents were part of a sector - wide insurgency and had ties to insurgents on Sammun and Denash . Around 2 BBY , Nightswan engineer ed the capture of Scrim Island in order to set a trap for the Chiss Admiral Thrawn , a rising star in the Imperial Navy . Fleet Admiral Jok Donassius dispatched Thrawn to retake Scrim Island but the Admiral insisted on studying the situation further . As a result , the mission was assigned to Admiral Durril , who launched a hasty attack that resulted in his 103rd Task Force sustaining considerable damage . Thrawn and Commander Eli Vanto managed to collect intelligence on the Scrim Island defenses and Nightswan . Using this information , Thrawn ' s 96th Task Force overwhelmed the insurgent defenses on Scrim Island , forcing their surrender . However , eight insurgent ships managed to flee to the main continent . Insurgent forces regrouped at Creekpath complex where they took control of the mine with the help of sympathetic locals . Vanto and Thrawn discovered that the rebels had regrouped at Creekpath and imposed a siege of the complex . Thrawn also used three damaged Imperial light cruisers to set a trap for Nightswan ' s insurgent fleet in space . The Imperial Security Bureau Colonel Wullf Yularen devised a plan to disable the insurgent ' s deflector shield by sending Agent Gudry to blow it up , enabling Thrawn ' s forces to attack the complex . In an attempt to avoid heavy civilian casualties , Thrawn secretly met with Nightswan and invited him to join the Chiss Ascendancy in return for peacefully surrendering his forces . While respecting Thrawn , Nightswan declined his offer since he did not trust Restos to show clemency to his followers . Shortly later , insurgent forces tried to attack the orbit ing Imperial fleet but were ambushed by three squadron s of TIE fighters hidden within repair barges . Despite Thrawn ' s efforts to minimize civilian casualties , all the insurgents and many civilians were killed when Pryce detonated Gudry ' s explosives in an effort to conceal his murder . Pryce had murdered Gudry after he threatened her parents . The Creekpath mine explosion brought an end to the Batonn sector insurgency . Despite the high civilian casualties , the Empire regarded the events on Batonn as a victory since it eliminated the remaining rebel forces in the sector . The Imperial Senate launched an inquiry into the bombing but found little evidence . However , Thrawn along with Yularen and Vanto privately suspected that Pryce was complicit in the bombing despite her professing innocence . Following the pacification of the Batonn insurgency , Thrawn was promoted to the rank of Grand Admiral and given command of the elite Seventh Fleet .
