During its history , it fought the Gungan – Naboo War with the Naboo . In 32 BBY , the Trade Federation invaded Naboo , enslaving the Naboo people and driving the Gungans out of Otoh Gunga . History . Formations . It was believed that the first Gungan " grand army " was to defend against Bursa s , large and dangerous animals . The grand army eventually drove the bursas to extinction . Sometime around 3000 BBY , the Grand Army formed at the peak of the War of the Gungan tribes when Boss Gallo united the Gungans to defeat the warlord Boss Rogoe . Sometime between 150 BBY and 121 BBY , the Grand Army engaged in an open war with the Naboo known as the Gungan – Naboo War . In 100 BBY , the Grand Army fought off unknown invaders of Naboo . As a result , the Gungan tribes were united even closer than they were after the War of Gungan Tribes thousands of years before . Every Gungan city was required to hold annual drills for its militiagungs so that the Grand Army could be assembled in thirty - six hours . Crisis on Naboo . In 32 BBY , the planet of Naboo was blockaded and invaded by the Trade Federation . By that time , the Grand Army had not been called for over 100 years . It had been maintained to defend against large predators and tradition . The Naboo people were entirely overwhelmed by the Trade Federation Droid Army , allowing the Droid Army to turn its attention to subjugating the rest of Naboo . The Droid Army swept through the swamps , driving out the Gungans from Otoh Gunga . When the Queen of Naboo , Padmé Amidala , returned from her voyage to acquire help , she met with the survivors from Otoh Gunga and convinced Boss Rugor Nass to help them . Boss Nass agreed to assist in retaking Naboo , and set about gathering and rebuilding the Grand Army . The Grand Army , sent out as bait for the Droid Army , was composed of two - thousand Gungans and was commanded by General Tobler Ceel under Boss Nass and the Bombad General Jar Jar Binks . The battle on the plains of Naboo weakened the Grand Army but they succeeded nonetheless by preventing the Trade Federation ' s army from intervening in Theed . 543 Gungans were killed and its leaders captured , but the destruction of the Droid Control Ship in orbit shut down the Droid Army . Clone Wars . During the Clone Wars , around the year 21 BBY , Jedi Grand Master Yoda contacted the Boss of Otoh Gunga , Lyonie , to ask for assistance in a battle . Binks , now a Senator , convinced Lyonie to assist . Binks , along with a portion of the Gungan Grand Army , was sent to Mon Calamari onboard a Venator Star Destroyer . Many Gungans died in that engagement while fighting Aqua droids , and many were captured when the Separatist leader Riff Tamson used a Trident vessel to create a whirlpool . The survivors were sent to a prison camp among Mon Calamari ' s coral reefs . Soon after , the Mon Calamari prince Lee - Char visited the camp and told the prisoners to wait for his signal before attacking . Lee - Char was captured and brought before Tamson , and was scheduled to be executed . The Quarren , Mon Calamari ' s other race , had joined the Separatist cause but betrayed the Separatists and freed the prisoners . The Grand Army was able to fight back , and some Gungans joined Captain Ackbar in taking down a " Trident " - class ship . The battle was ultimately won , and Lee - Char was crowned king . At a later time , there was unrest on Naboo . Rumors were circulating that the Gungans allied with the Separatist Alliance . Boss Lyonie was calling on the Grand Army to march on Theed . Amidala , now Naboo ' s senator , along with the Jedi Knight Anakin Skywalker , returned to Naboo to defuse the situation . They met Binks on Lake Paonga , and the Gungan took them to Otoh Gunga to meet Lyonie . The Boss rejected their help , but Skywalker realized Lyonie was under a form of mind control from a necklace given to him by Minister Rish Loo . The Jedi crushed the necklace and freed Lyonie . Lyonie then confronted Loo , who betrayed the Boss and stabbed him . Loo escaped from Otoh Gunga and went to the surface to inform the Grand Army that Lyonie was dead and rally them to march on Theed . Lyonie survived his wound but was unconscious . Skywalker saw that Binks resembled the Boss , and convinced him to pose as Boss Lyonie to call off the Grand Army ' s attack . They went to the surface , and Binks was able to fool the Grand Army into believing that he was Lyonie . Rish Loo , seeing that his ruse had failed , escaped deeper into the swamps on a Flitknot speeder bike . Three C - 9979 landing craft then entered the area and landed . One disgorged a tactical droid with a B2 super battle droid escort . Binks and General Tarpals followed the tactical droid onto the landing craft , where they met General Grievous . Binks , still posing as Lyonie , told the cyborg general that he wasn ' t going to go through with the attack . That angered Grievous , and Binks acquiesced and ordered Tarpals to prepare the troops . Tarpals disembarked and contacted Amidala , who suggested a strategy . Binks , meanwhile , stalled for time , but Grievous saw through the ruse and attempted to kill him . Binks escaped off the craft and saw that the Grand Army had succeeded in shutting down the droid army and was gathered around to try to capture the Separatist general . Tarpals and several other warriors engaged the general in the duel . Grievous fatally stabbed Tarpals , who used his sacrifice to impale the cyborg leader with a spear , distracting him long enough for the other warriors to hit him with boomas , knock him down , and capture him . Skywalker chased Rish Loo to his secret outpost , which was in use by Count Dooku , the head of the Confederacy of Independent Systems . Dooku killed Loo , then dueled Skywalker . Skywalker was subdued and captured , and Dooku contacted Amidala , offering a prisoner exchange : the Jedi for the General , and gave her one hour to decide . Later , a Sheathipede shuttle arrived near the gathering of the Grand Army . The tactical droid delivered the wounded Skywalker to the Naboo contingent , and the Grand Army let Grievous go . The Separatist army then left Naboo . Neeyutnee , Naboo ' s current Queen , praised Binks for reuniting the Naboo and the Gungans again . Galactic Civil War . In the period after the Battle of Yavin , Grand Army militiagungs and Generals could be found in various Naboo cities . In 4 ABY , the Grand Army aided the Naboo in ridding the planet of the Galactic Empire . Organization . The Grand Army could only be called by the reigning Boss of Otoh Gunga . Equipment and vehicles . The Gungans primarily use organic technology and grow their vehicles and weapons . Much of their equipment is hand - crafted . The Grand Army ' s strategy was defensive - oriented with their deflector shield generators mounted on their large animals , the fambaas . The deflector shield blocked laser blasts but allowed slower - moving objects in . The Gungan offensive weaponry consisted of spears , atlatls , Electropole and cestas for throwing boomas . Gungan battle wagon s pulled by falumpasets carried large energy balls for use in catapults . The Gungans also used bongo s for transporting supplies . The Grand Army used kaadus as mounts for their officers and as cavalry , with their riders using flamethrowers . Other kaadus were mounted with weapons to serve as anti - infantry units . The Grand Army also used biological units as heavy weapons , such as cerrabore s and lerraa s , and swifts . Other heavy weapons included raaptur s . Glurrg s assisted the Grand Army as workers . Behind the scenes . The Gungan Grand Army appears in material relating to the release of . " " The New Essential Guide to Alien Species " states that the first Grand Army was formed in 100 BBY to fight off unknown invaders and unite the Gungan tribes . However , this conflicts with the fact that it was in existence thousands of years before during the War of Gungan Tribes and the Gungan - Naboo War . Another contradiction in the " " is the existence of the Gungan - Naboo War . One source states that a war occurred between 150 BBY and 121 BBY . The " New Essential Guide to Alien Species " states that there was never a war between the Gungans and Naboo . In the 2001 video game " , " the Gungan Grand Army gets its own campaign narrated by Boss Nass . The game chronicles its formation under Boss Gallo and skips to the Invasion of Naboo . The last mission is an alternate history scenario where the Grand Army outright wins the Battle of Grassy Plains and liberates Theed . The last mission in the OOM - 9 ( Droid Army ) campaign is another alternate history scenario where the Droid Army defeats the Gungan Grand Army . The same game also establishes that , in addition to its ground army , the Gungan Grand Army also possessed a Navy ( of both the aquatic and starfaring varieties ) , a mechanized army , an air force , and a heavy weapons division .
