Battle of Bothawui ( Galactic Civil War ) The Battle of Bothawui in 19 ABY was , along with the Battle of Yaga Minor , the final clash between the New Republic and the Imperial Remnant . Though it marked the end of the Galactic Civil War which began with the Rebellion against the Galactic Empire , it nearly became the beginning of a new civil war over the Caamas Document . Imperial preparations . Early in the Caamas Document crisis , the resurrected " Grand Admiral Thrawn " really the con - artist Flim sent three " Imperial " - class Star Destroyers to the Both system . The lead vessel was the " Tyrannic " under the Kuati Captain Nalgol . The " Obliterator " under Captain Trazzen and the " Ironhand " under Captain Argona were also deployed , together with a few small scout vessels in civilian disguise . All three Star Destroyers were assigned to moor themselves to a comet and lie in wait , with their cloaking devices engaged . When Imperial saboteurs caused a failure in Bothawui ' s planetary shields and instigated a battle between pro - and anti - Bothan forces in Bothawui orbit , they would then be ready to destroy both fleets and devastate the surface of Bothawui . In the meantime , Imperial Intelligence agents helped inflame tensions over the Caamas Document and the allegations of Bothan collusion in the Caamasi genocide . Led by agent Navett , the Imperials committed acts of sabotage and instigated riots on several planets , including Bothawui . These acts of violence combined with pre - existing tensions over the Caamas question and other conflicts and grievances between New Republic members . It appeared that the New Republic government was unable to stop the spread of violence . Indeed , General Wedge Antilles had been unable to stop Leresen forces from destroying a zero - gravity crystal factory in Bothawui orbit as revenge for the death of two Leresai in the Bothawui riot . Soon , over fifty - six vessels had arrived in the Both system , either to threaten or to defend the Bothans . This number would quickly increase : by the time of the final battle , the combined pro - and anti - Bothan forces contained nearly two hundred capital ships . The New Republic only had a token force in - system to keep the two fleets apart . They were assisted by a handful of neutral vessels , including an Action II transport from Pakrik Minor commanded by Carib Devist . Devist was a clone of the Imperial war hero Soontir Fel , and a former member of an Imperial sleeper cell , but he had recently defected to the side of the New Republic . A larger New Republic force , commanded by General Garm Bel Iblis , was supposedly near Kothlis , but this force was really massing in the Mrisst system for the raid on Yaga Minor . Republic response . The New Republic suspected that the Imperial Remnant was manipulating these tensions . Correctly assuming that the Imperials intended to sabotage Bothawui ' s shields to allow the anti - Bothan forces to bombard the planet , General Garm Bel Iblis sent Wedge Antilles and Corran Horn to go undercover to investigate and forestall possible Imperial sabotage . In the city of Drev ' starn , they were joined by Moranda Savich , an agent of the smuggler Talon Karrde on a similar mission . Navett ' s team — himself , Klif , Pensin , and Horvic — was rattled by their activities . This led to constant changes in the timetables for attack that Navett would send to Captain Nalgol via the disguised support vessels . However , Antilles and Horn were called away to join Bel Iblis ' raid on Yaga Minor , and Savich was unable to contact Bothan authorities due to her criminal status . As tensions continued to build , Leia Organa Solo and the Caamasi Senator Elegos A ' Kla arrived in the " Millennium Falcon " after preliminary secret peace negotiations with Imperial Admiral Gilad Pellaeon . Their arrival interrupted a near - skirmish between the Ishori flagship " Predominance " and four Diamal an and Sif ' krie vessels . The two dignitaries and their Noghri bodyguards were escorted to a New Republic corvette carrying Chief of State Ponc Gavrisom . They were soon joined by Han Solo and Lando Calrissian , who had returned on Calrissian ' s yacht " Lady Luck " from a mission to recover the Caamas Document from Bastion . The New Republic dignitaries had to buy time . Lando Calrissian went on board the Diamalan flagship " Industrious Thoughts " to meet with Diamalan Senator Porolo Miatamia . Meanwhile , Organa Solo and Gavrisom went to talk with the Ishori leader , Captain Av ' muru . Han Solo announced to both sides that he had the complete Caamas Document , which would show which Bothan leaders had colluded with Emperor Palpatine to destroy Caamas , but that he would not give it up until both sides backed down . Even if the two fleets did back down , however , he knew that this would not resolve the issue — his copy , which was given to him by " Thrawn " ( i . e . , Flim ) himself , was altered by the Imperials and therefore worthless . The battle begins . Back in Drev ' starn , Moranda Savich started a fire in the pet store Navett was operating as a front . This forced the saboteur ' s hand , causing Navett ' s team to begin their sabotage operation early . While , Navett and Klif took down the shields near Drev ' starn , Pensin and Horvic infiltrated the " Predominance " and fired on the city . They also jammed the frequencies carrying Gavrisom ' s plea for calm , and sent false orders to several of the flotillas in the system ( including the Corellians , Mon Calamari , Diamalan , and Ishori ships ) to begin their attack . The cloaked Star Destroyers , whose crew had become frustrated by endless delays in Navett ' s plans , were caught unready as the operations were suddenly moved up . Nevertheless , they went into position as the pro - and anti - Bothan ships began firing on each other . During the melee , the " Millennium Falcon " ( with Han Solo and Elegos A ' Kla on board ) and Devist ' s Action II transport came across the cloaked " Tyrannic " . The two freighters were caught in the Star Destroyer ' s tractor beam . Though they were behind the " Tyrannic " ' s cloak , Leia Organa Solo could sense a disturbance in the Force from her husband ' s discovery . Lando Calrissian also noticed the " Falcon " ' s disappearance . After convincing Senator Miatamia to use a diplomatic channel to contact Leia , they deduced that Han dropped into a cloaking shield . Leia used the Force to adjust the " Predominance " ' s helm controls , and helped Gavrisom convince Captain Av ' muru to continue on an intercept course towards the comet . Lando convinced the Diamala to follow . Meanwhile , Devist ' s freighter had launched twelve TIE / IN interceptors ( repainted with New Republic markings ) , which destroyed the tractor beam emplacements holding the two freighters in the cloaking field . As the " Falcon " escaped , revealing the Imperial ruse , all three Star Destroyers dropped their cloaks . Imperial retreat . The pro - and anti - Bothan forces , faced with a common enemy , began the attack . Lando Calrissian accepted a temporary renewal of his General ' s commission from President Gavrisom and took command of the combined fleets . Han Solo used Borsk Fey ' lya ' s private communication channel to call on his clan ' s private security forces for reinforcements - but ensured that his call leaked to other Bothan clan leaders . With the approximately 110 capital ships remaining from the first phase of the battle , and the one hundred Bothan starfighters and small capital ships arriving as reinforcements , Captain Nalgol realized to his chagrin that he was outmatched . The Imperials beat a hasty retreat to Bastion , intending to demand from " Thrawn " an explanation for his plan ' s failure .
