Ambush at Kestavel The Ambush at Kestavel was an event that took place several months after the creation of the Galactic Empire in 19 BBY , which nearly resulted in the assassination of the Empire ' s primary enforcer , Darth Vader . Prelude . The assassination attempt on Vader had been planned for at least several weeks beforehand , with Dass Jennir reluctantly carrying out the plot , having just settled for a comfortable life . However , the ambush nearly ended before it could begin due to distrust among Jennir ' s allies about keeping secrets from each other , as well as the machinations of Jedi Master - turned Sith agent , Beyghor Sahdett . Afterwards , the " Uhumele " captain , Schurk - Heren revealed to Bomo Greenbark that he managed to pick up a large supply of explosives , an idea he had come up with since Greenbark saved the group on Mimban . In addition , they also planned on allowing the Imperials to cross over to the second bridge before ambushing them , due to the bridges being a chokepoint alongside the archway tunnel preceding the casino , as well as coming up with a strategy to cull the Imperial forces . The ambush . Eventually , holed up inside Kestavel ' s local hotel , The Lucky Twi ' lek , Greenbark , Kai Hudorra , and Jennir waited out for Vader ' s arrival , having earlier flooded the main entrance with enough engine fuel to cover the bridge when released . When Greenbark sighted Vader arriving via the second gate , Jennir told Greenbark to leave him , also ordering him to flee to the canyons until it is safe , then upon arriving at the " Uhumele " , tell Captain Heren not to spare the engines when leaving . Huddora then witnessed the arrival of Vader ' s forces , as well as their disarming the explosives under the second arch under Vader ' s command , privately remarking that he expected Vader to bypass that particular trap . Vader , likewise , sensed both Jennir and Huddora inside the hotel , and deduced that the former made an ally . Jennir then opened the impromptu floodgates and released the engine fuel . Vader then jumped up to the gate ' s wall as the engine fuel covered his stormtrooper troops . Immediately after they informed Vader of what the fluid was , also citing they should retreat until the fuel evaporated and forbidding anyone to fire their weapons , they saw a spark thrown out of a window to the flooded bridge . Elsewhere , on the surface of the " Venator " - class Star Destroyer " Hound " , Lieutenant Gregg got into an argument with the other Imperial officers on standby , as Vader had ordered them to not interfere on his behalf , with Gregg also pulling his blaster on one of the officers to ensure the order was followed , before he witnessed from afar a blaze at the location of The Lucky Twi ' Lek . A communication popping up shortly thereafter stated that all communications were lost . This led Gregg to believe Vader to have been killed . In actuality , Vader narrowly evaded the fire , resulting in his cape being singed . Vader entered The Lucky Twi ' lek , finding only Hudorra waiting for him . The two dueled until the Bothan Jedi Master attempted to activate a thermal detonator , which would trap them under the rubble if not kill them outright . Vader used the Force to stop Hudorra , stunning him momentarily and giving him the chance sever his hand . After attempting to interrogate Hudorra , who would reveal nothing about Jennir , Vader killed him . Vader then followed the Force signature of whom he thought was Jennir , only to discover Sahdett bound and gagged . After questioning his presence , he decapitated the Verpine in anger . Bomo then arrived at the " Uhumele " , and boarded inside with the two remaining crew to board , hastening the boarding before being spotted by mist creatures . The " Uhumele " managed to escape into space . Jennir also ended up unwittingly escaping , due to Hudorra drugging his drink earlier .
