Battle of Baskarn The Battle of Baskarn was a minor battle in the Galactic Civil War , in which an Imperial commander in charge of a long range recon mission discovered the secret Rebel Advance Base Baskarn and decided to attack on the spot . Prelude . Prior to the battle , Colonel Riskin had sent out a team of elite jungle specialists to investigate the disappearance of a five - soldier reconnaissance squad in the jungle . The team found out that the recon squad had been killed and eaten by a large predatory flightless bird , and subsequently , their weapons had been stolen by a tribe of Yrashu called the Low Ones . Joining forces with a friendly tribe of Yrashu , the jungle team defeated the Low Ones . Observing how clumsily the Rebels conducted themselves in the jungle , the Yrashu offered to teach them the Yrashu way of jungle survival in a session called a momu , which lasted nearly two weeks . The jungle team was , as required by Yrashu culture , adopted into the tribe and sent into the jungle accompanied by Yrashu tutors . By observing the momu , the jungle team learned the Yrashu way of moving safely and quietly in the jungle — which required as little clothes as possible and no equipment , as clothes could get stuck in the growth of the jungle — climbing trees including the deadly razor tree s , jungle camouflage , gathering fruits and berries , stalking prey , shaking predators such as the giant hrosma tiger , and breathing under water due to symbiotic bacteria that would invade the lungs of organic beings . Upon completing the momu and creating close bonds with the Yrashu , the Rebels returned to the Advance Base Baskarn , where they were presumed missing in action , having been absent for two weeks . Jungle tactics . Upon returning , the jungle specialists learned from Riskin and his second - in - command , Major Talsa that an Imperial recon fleet consisting of two " Lancer " - class frigates and " Star Galleon " - class frigate had appeared out of hyperspace and had initiated an invasion . The ion cannon of the base fired a few shots through the small shield of the base , but then a computer malfunction caused the shield to break down facilitating the Imperial invasion . Upon the breakdown of the shield , Rebel starfighters were dispatched to thwart the invasion , but Imperial drop ships had already managed to land a force of sixty stormtroopers and two AT - STs half a kilometer south of the Rebel base . Riskin , realizing that the outmanned Rebels might have an advantage in the newly acquired jungle skills of the Rebel jungle specialists who had gone through the momu , assigned them twenty regular Rebel soldiers and sent them to intercept the Imperial force . The Yrashu agreed to assist the Rebels now that some of their number had become part of their tribe . While the twenty regular soldiers proved to be more of a liability than a help , making noise , getting lost , and being attacked by predators , the Yrashu and the jungle specialists were highly efficient . The sixty stormtroopers marched in two wedges of thirty flanking the AT - STs who walked side by side in the middle . Virtually naked and armed with Yrashu mace s , the Yrashu - trained Rebels and the Yrashu , using jungle Yrashu guerrilla tactics , attacked the stormtrooper wedges , while the twenty regular soldiers were spread out in front of the Imperials to attract their attention . Attacking from the right flank , the Yrashu managed to take out some twenty stormtroopers before being forced into hiding by a barrage of AT - ST fire . The Yrashu - trained Rebels attacked the left wedge , taking out a similar number . Having taken out some forty stormtroopers , the Rebels and Yrashu , lured the remaining forces back towards the Rebel base into a small minefield . The combination of the minefield , and clever jungle tactics lead to the disablement of the AT - STs , and the regular Rebel forces had no problems defeating the remaining stormtroopers . In the meantime , the Rebel starfighters had managed to chase off the Imperial forces during the orbital battle , and possibly shot down the " Star Galleon " - class frigate . Aftermath . After the battle , the Yrashu agreed to train more Rebels in the Yrashu ways of jungle survival , which lead to the establishment of a Rebel team of jungle specialists , using Yrashu tactics and skills , who went on jungle missions all over the galaxy . This group within the Rebellion was characterized by a strong sense of camaraderie and secrecy , since it was not allowed to discuss the momu with non - members of the Yrashu tribe .
