Around 22 BBY , early in the Clone Wars , the Confederacy of Independent Systems initiated an invasion against the peaceful world of Nexus Ortai , hoping to conquer the planet because of its strategic position at the crossroads of hyperspace lanes . In order to defend the planet , a Galactic Republic fleet — commanded by Admiral Wullf Yularen , High Jedi General Obi - Wan Kenobi , and Jedi General Anakin Skywalker — engaged Confederate " Munificent " - class star frigates and Vulture droid starfighters above Nexus Ortai . Kenobi and Skywalker , flying Delta - 7B " Aethersprite " - class light interceptors , led V - 19 Torrent starfighters of Ghost Squadron against the Confederate Vulture droids . Skywalker ' s Padawan , Ahsoka Tano , was willing to fight alongside her master , but the latter forbid her to do so , ordering Tano to stay aboard one of the Republic ' s " Venator " - class Star Destroyers and learn from Yularen . After both sides had sustained heavy damage , Skywalker ordered Ghost Squadron to attack the Separatist command ship , while he and Kenobi took care of the droid starfighters . Despite Kenobi ' s protests , Skywalker took many droids by himself and demonstrated his exceptional piloting skills by destroying them . Soon , Ghost Squadron succeeded in destroying the command ship , and the Republic considered the Separatists to be finished . At that point , however , more Separatist starships arrived , commanded by General Grievous . Realizing that their forces could not hold off against the Confederate reinforcements , Kenobi ordered Yularen to prepare the fleet for withdrawal , much to Skywalker ' s dismay . After picking up the two Jedi and remaining pilots of Ghost Squadron , the Star Destroyers jumped to hyperspace and retreated to Republic territory . Aftermath . The loss of Nexus Ortai marked nearly two dozen worlds that the Republic had to pull back from in the Mid Rim region of the galaxy . The main reason for this was revealed to be the Confederate Navy ' s advantage in size , giving them four times as many ships as the Republic . To this end , Jedi Master Mace Windu proposed to strike at one of the InterGalactic Banking Clan ' s shipyards producing warships for the Confederacy . Skywalker then formulated a plan to infiltrate the Separatist - controlled Gwori system and destroy the shipyards located there . Behind the scenes . The battle of Nexus Ortai was featured in the 2008 graphic - novella " " , written by Henry Gilroy and illustrated by the Fillbach Brothers , which serves as a tie - in to . Although " The Official Star Wars Fact File " Part 29 places " Shipyards of Doom " between " " and " Rookies , " this article disregards that chronological placement due to the fact that " Clone Wars Gambit : Siege " and " Rookies " take place in 21 and 22 BBY , respectively , leading to an error in chronology .
