Second battle of Cularin The Battle of Cularin was fought in the Cularin system , near to the end of the Clone Wars that resulted in the demise of Jedi Master Darrus Jeht and the Confederate superweapon " Shadowblade " . Prelude . Following the declaration of Order 66 , an order that called for clone troopers to kill their Jedi commanders , Jedi Master Darrus Jeht prevented the clones who served under him from learning about the order , by disabling the long - range communications aboard his ship , the " Maelstrom " . The " Maelstrom " arrived in the Cularin system and there , its sensors revealed that two Republic gunships , the " Primal " and the " Undaunted " , were firing on Jedi starships that were fleeing the planet Almas . Jeht told his crew that the two capital ships had been taken over by the Confederacy of Independent Systems and planned to attack them , using the " Maelstrom " . The battle . Jeht ' s deceit . Jeht sent a short - range signal to the " Primal " and the " Undaunted " , informing them that the " Maelstrom " had been ordered to hunt down targets in the inner regions of the Cularin system . The two ships parted to let Jeht ' s ship pass and when it was between them , it opened fire . The two gunships were taken by surprise and the " Undaunted " began to leak plasma from its engine decks , and listed to the side . The " Primal " was less damaged , but still had it ' s weapons arrays brought offline . The Jedi Master ordered starfighters to launch from the " Maelstrom " . His astromech droid , R - 0 , began broadcasting false CIS binary control signals in the space surrounding the ship , leading Jeht ' s clone troops to believe that the starfighters from the " Primal " and " Undaunted " were being controlled by battle droids . The clones then detected that the " Maelstrom " was the source of the signals and came to the conclusion that the Confederacy was trying to take control of the warship ' s control system . Jeht ordered them to lock out all external communications and to bring down the primary communications array , supposedly to stop the CIS signals . The " Maelstrom " took a hit on it ' s starboard side , then turned around and fired on the " Undaunted " , causing the stricken vessel to explode . The " Primal " had brought it ' s weapons back online and fired on the " Maelstrom " , causing damage to its port main thruster . Jeht told his crew to turn off the " Maelstrom " ' s engines and overburn the vessel ' s bow thrusters , even though the thrusters were not designed for use in the space . The effect of this was to flip the " Maelstrom " over while propelling it forward , and it took the crew of the " Primal " by surprise . The " Maelstrom " fired all of its forward guns and the " Primal " exploded . The arrival of the " Shadowblade " . With the battle seemingly won , Jeht planned to leave in his starship , the " Legacy " , before the clones learned Order 66 . However , his plans were interupted by the arrival of the " Shadowblade " , a Separatist superweapon that Jeht had believed to have been destroyed . The Separatist vessel was on a course towards the planet Cularin , the system ' s primary world and Jeht determined to stop it . However , the " Maelstrom " was unable to fire it ' s main guns , because their cores had been shattered by firing just after the ship ' s reversal . With no other option left , Jeht decided to attempt to destroy the " Shadowblade " by ramming it with the " Maelstrom " , in a suicide attack . The " Shadowblade " headed through the Cularin system asteroid belt en route to Cularin . To try and catch up with it , Jeht brought the " Maelstrom " through some secret , asteroid - free routes through the belt , details of which had been given to him years earlier , by the crime lord Nirama . He also told R - 0 and Millinae Untaire to leave the " Maelstrom " and flee aboard the " Legacy " . When the " Shadowblade " emerged from the asteroid belt , the " Maelstrom " ' s crew lost their sensor lock on it , due to the presence of time rifts , which were left over from when the Darkstaff had caused the Cularin system to disappear from the galaxy for ten years . Jeht ordered his crew to fire torpedo s at the " Shadowblade " , even though they had little chance of penetrating the CIS ship ' s shields , or being targeted effectively , due to the " Shadowblade " s cloaking device . None of the torpedos caused any damage to the " Shadowblade " , but they alerted it to the presence of the " Maelstrom " , so the superweapon changed course , to intercept the Republic warship . Jeht wanted to lure the " Shadowblade " towards the " Maelstrom " , so that he could cause it to pass through one of the time rifts , preventing it from attacking Cularin . The " Shadowblade " opened fire and caused severe damage to the " Maelstrom " with it ' s first volley . It then fired a second volley , causing seven of the " Maelstrom " ' s decks to vent out into space . However , the " Maelstrom " then activated it ' s tractor beam and pulled the CIS vessel towards a time rift . Both ships plumetted through the rift and disappeared .
