Duel on Yavin 4 This Duel on Yavin 4 was a lightsaber battle between Jedi Padawan Anakin Skywalker and Dark Jedi Asajj Ventress that took place in 22 BBY on the jungle moon of Yavin 4 , during the Clone Wars . Ventress had been dispatched by her Master , the Sith Lord Count Dooku , to prove herself by assassinating Skywalker , who was at the time leading his clone forces during the Battle of Muunilinst . Skywalker was piloting his Jedi starfighter in space over Muunilinst when he sensed the presence of Ventress , who flew her own starfighter , through the Force . Skywalker pursued the Dark Acolyte to Yavin 4 against the orders of his Master , Obi - Wan Kenobi and , in response , Kenobi sent a squad of clone troopers to provide support for his apprentice . Soon after landing , the squad was wiped out by Ventress , who also destroyed Skywalker ' s starfighter and astromech droid . The assassin revealed herself to Skywalker and the two engaged in combat . Dueling through the forest , Ventress goaded Skywalker as they approached an ancient Massassi Temple , where they continued their fight . After losing his lightsaber and confiscating one of his opponent ' s , Skywalker drew on his hatred of Ventress and attacked her with great force . His blows caused the cliff she stood upon to break and she fell into the ravine below . Seemingly victorious , the Padawan assumed she had died and acquired her ship as a means of getting off the planet . However , Ventress had survived and went on to fight in future Confederate campaigns . Prelude . Immediately upon arrival , Jedi Padawan Anakin Skywalker briefly explored his surroundings , and , after the arrival of a platoon of clones that had arrived via a CR - 20 troop carrier on the orders of his Jedi Master , Obi - Wan Kenobi , began to seek out his mysterious challenger . Ventress , however , was able to ambush and kill off all of the clone troopers , destroying their transport and Skywalker ' s starfighter , the " Azure Angel " , along with R4 - P22 before revealing herself , approaching the young Jedi as she emerged from within the flaming wreckage and igniting her weapons . The duel . As the duel began , however , Skywalker proved that he was able to hold his own against Ventress despite her command of the dark side of the Force . As Skywalker was about to strike , Ventress Force pushed him , avoiding the attack . Skywalker returned the favor with another Force Push , Ventress then answered by throwing a tree at him . Skywalker performed " sun djem " and managed to knock both lightsabers that Ventress had drawn out of her hands . However , when he went to finish her off , she leaped into the treetops and pulled both swords back to her . Skywalker swiftly followed , but then he lost sight of her . Ventress used the Force to snap the branch Skywalker was on , but as he fell he managed to hang onto a vine , which was then also cut by Ventress . The antagonists leapt through the jungle , going deeper and deeper into the forests of that moon and using the Force to hurl entire trees at each other as they fought , jumping from tree to tree and cutting vines they swung on . Eventually they landed on a raised walkway and Ventress attempted to use Dun Möch to knock Skywalker from the walkway . Skywalker attacked , forcing Ventress to back off in the face of his assault . Soon he forced her into a Massassi Temple ; once inside their battle became even more violent as they made their way to the higher levels . Viciously utilizing the Force against Ventress , Skywalker hurled her backwards ; she attempted to retaliate in kind by hurling loose boulders at the Padawan , but he deflected them , Force pushing her against a wall so hard that it shattered . The battle , which had degenerated into an all - out brawl , moved outside onto the rain - slicked ledges and stairways of the temple . Both combatants , their robes tattered and soaked from the rain , paused and regarded each other . The lightsaber duel soon resumed its violent tattoo . Ventress was able to knock Skywalker ' s lightsaber out of his hand , but before she could capitalize on this opportunity for a killing blow , he responded by catching her by the wrists . Drawing upon his anger , he crushed her left wrist with his mechanical hand , causing her to drop the saber she held much to her own abject shock . Taking up her lightsaber , Skywalker continued to strike at her with vicious slashing attacks and power lunges , driving her back to the edge of the temple peak . He struck harder and harder until the force from the attacks made the stone she was standing on crumble , causing her to fall off of the edge of the temple and into the jungle depths . Skywalker then roared in rage . As a result of giving into his anger once again , Anakin took yet another step closer to the Dark Side of the Force . Aftermath . Assuming that she was dead , Skywalker tossed the lightsaber that he had seized over the precipice ; he then commandeered Ventress ' s Ginivex - class starfighter and returned to Muunilinst where , following the battle , Obi - Wan berated him for ignoring orders and running off on his own and expressed his concern about the Sith ' s interest in Skywalker . In actuality , Ventress survived the fall , and left the planet . She returned to her Confederate allies and continued to fight against the Republic . Some time later , Palpatine sent Mas Amedda to the moon to acquire piranha beetles and a Massassi frieze . Almost 22 years later , when Palpatine ' s new battle station arrived near Yavin 4 to destroy the Rebel Alliance , Skywalker , as the Sith Lord Darth Vader , would recall the duel with Ventress on this moon .
