First Battle of Bothawui The First Battle of Bothawui was a naval conflict between the Sith Empire and the Galactic Republic during the Great Galactic War . Following the return of the Empire and its initial victories in the Outer Rim Territories in the early stages of the war , the Sith Emperor turned his sights toward the Mid Rim in 3671 BBY , with Bothawui as his first target . Admiral Greik of the Republic Navy predicted the attack , and so took approved the daring tactics of the combat analysis droid B - 3G9 and assembled the entirety of his fleet of warships over the world . The incursion , led by Darth Immern , was a disaster for the Empire , as the Republic force was ready for the attack . The entire Imperial Armada strike fleet was wiped out , but the Empire ' s defeat during its first attempt at taking Bothawui only served to provoke their second , more aggressive attack . Prelude . Since the start of the Great Galactic War in 3681 BBY , the Sith Empire was widely successful in its campaigns in the Outer Rim Territories , but only made minor incursions into the Mid Rim . Even these negligible attempts at expanding the war were often met with failure , but after the Imperial seizure of the Seswenna sector in the Outer Rim in 3671 BBY , the Sith Emperor began planning his military ' s full forward progression toward the Core Worlds . The first step in this plan was to finally conquer the Mid Rim — more specifically , the Bothan sector . Anticipating this development , Admiral Greik of the Republic Navy began planning a counterattack ; in a strategy devised by the expert combat analysis droid , B - 3G9 , Greik amassed the entirety of the Republic fleet in the Both system to defend against an Imperial invasion of the planet Bothawui . The battle . Believing that the forces of the Republic Navy were still recovering from the Outer Rim campaign , the Imperial armada hastily rushed into Bothan Space . From aboard his personal cruiser , Imperial commander Darth Immern led a fleet of " Harrower " - class dreadnoughts into a severely mismatched battle against the entire Republic fleet in orbit above Bothawui itself . The Republic force , consisting of numerous " Thranta " - class corvettes and at least one " Valor " - class cruiser , the " Intercessor " , battered the Sith forces into submission . The Imperial fleet was caught completely off - guard and was quickly overwhelmed by the Republic vessels , which obliterated all of the invading forces , including Darth Immern himself . The Kel Dor Jedi Knight Gnost - Dural , who had recently been transferred to the Republic Navy after serving for many years in the embattled of the Minos Cluster , served with the fleet during the battle , as did the Bothan Jedi Kutri O ' a . Aftermath . The conflict at Bothawui was the Republic ' s first major victory against the Empire since the war had begun . News of the battle spread across the HoloNet , restoring the morale of the people of the Republic and reinvigorating its jaded military . The bulk of Bothawui ' s defense forces soon moved on , once again scattering throughout the galaxy to combat the Empire . To protect from retribution , the Republic commissioned engineers to construct a new , high - powered planetary shield on Bothawui ' s surface . To protect the shield itself , a dedicated contingent of Jedi and Republic soldiers remained on the planet in anticipation of the Empire ' s retribution . The Empire indeed returned , this time with a massive invasion army intended to overwhelm Bothawui . The remaining Republic forces under the command of Jedi Master Belth Allusis were wiped out during their fight to protect the planet , but were ultimately able to repel the Sith from Bothawui . The battles at Bothawui restored hope to a discouraged Republic and empowered its defenders to continue fighting the war for several decades . B - 3G9 , the droid hero of the First Battle of Bothawui , was rewarded for the victory with an order for it to be upgraded and undergo maintenance at its Czerka Corporation factory of origin . However , due to an administrative error , the droid underwent a partial circuit remapping to remake it as a standard protocol droid . The mix - up diminished B - 3G9 ' s tactical analysis programming , removing it from command status but allowing it to continue serving the Republic as a manager of individual starship defense systems . Another droid involved in the battle , MZ - 12 , was Darth Immern ' s astromech droid who served aboard the Sith Lord ' s cruiser . After Immern ' s death , MZ - 12 sought out new masters to serve within the Imperial Armada . Following the conclusion of the war with the signing of the Treaty of Coruscant , the then - Jedi Master Gnost - Dural made a holorecord that detailed the Empire ' s attempts at taking Bothawui . Additionally , his journal of war stories , which included an account of the battle over Bothawui , was added to the Jedi Archives on Tython by Grand Master Satele Shan , who also included an anecdote regarding the Bothawui victory . Behind the scenes .
