Rescue of Adi Gallia / Legends In the second year of the Clone Wars , Jedi General Plo Koon launched a Galactic Republic mission to rescue Jedi Master Adi Gallia , who had been previously captured by General Grievous of the Confederacy of Independent Systems . After locating Grievous ' s flagship in space , Koon took a fleet of five Republic Star Destroyers to ambush the Separatist dreadnaught . Boarding Grievous ' s flagship with the Republic Grand Army ' s 104th Battalion , Koon and his clone troopers fought through the warship ' s battle droid defenders while Clone Commander CC - 3636 , nicknamed " Wolffe , " took a squad to rescue Gallia from the ship ' s bridge . Grievous was forced to flee from his overwhelmed flagship , allowing Wolffe to rescue Gallia . The Republic emerged victorious , while Koon and Wolffe also retrieved the Republic droids C - 3PO and R2 - D2 , who had been stranded on Grievous ' s flagship after a series of escapades . Prelude . During the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems , the Confederate General Grievous gained notoriety for targeting members of the Jedi High Council . Such was the case in 21 BBY , the war ' s second year , when he ambushed Jedi Master Adi Gallia ' s flagship near the planet Patitite Pattuna . Gallia ' s " Venator " - class Star Destroyer was crippled in the assault , and she was taken into custody aboard Grievous ' s " Providence " - class carrier / destroyer while her cruiser was destroyed . It was not long before Jedi General Plo Koon , a fellow member of the Jedi Council , received word of Gallia ' s capture and set out to rescue his comrade . Commanding a fleet of five " Venator " - class Star Destroyers , Koon located Grievous ' s destroyer in space , just after Grievous had ordered his battle droid crew to attack the Weequay pirate ship " Marauder " for target practice . The protocol droid C - 3PO and astromech droid R2 - D2 , both belonging to Republic Senator Padmé Amidala , were aboard the " Marauder " at the time that it was targeted by Grievous . Although they managed to escape from the pirate ship ' s destruction , they were forced to come aboard Grievous ' s flagship and were subsequently set to be incinerated into scrap metal for the Confederacy . The rescue . Immediately after emerging from hyperspace near Grievous ' s destroyer , Koon ' s five - cruiser fleet of Star Destroyers began to exchange heavy turbolaser fire with the Separatist dreadnaught . The Republic fleet quickly gained the upper hand , launching squadrons of ARC - 170 starfighters and BTL - B Y - wing starfighter s to challenge the destroyer ' s defenses . The clone trooper pilots moved in with their starfighters and assaulted the enemy battleship , hitting several places along its hull . Koon was thus able to board the destroyer with a rescue team , taking the clone troopers of the Grand Army of the Republic ' s 104th Battalion to push through the Separatist battle droid forces . While Koon and his men from the 104th Wolfpack squad fought B1 battle droids in one of the vessel ' s hallways , Clone Commander CC - 3636 , nicknamed " Wolffe , " took another squad of troopers to the bridge , where Gallia was being held in custody . Wolffe and his men were successful , rescuing Gallia from the Separatists , and they rendezvoused with Koon to join his fight against the battle droids . Between the Jedi ' s lightsabers and the clones ' blasters , they were able to defeat the squad of droids . His droid troops overwhelmed , Grievous fled from his flagship , leaving the Republic forces to eliminate the remainder of the battle droids aboard the Separatist warship . Aftermath . The mission was a success for the Republic due to Koon ' s rescue of Gallia . The wayward C - 3PO and R2 - D2 — having avoided being incinerated by the Separatists — were also rescued , coming upon Wolffe , Gallia , and Koon while aboard Grievous ' s destroyer . Having delivered the two droids earlier to Gallia ' s flagship from the planet Aleen , Wolffe could not believe it when he and the others found the droids aboard the Separatist dreadnaught , though Wolffe was less than pleased when the talkative C - 3PO began thoroughly recounting their adventures since escaping from Gallia ' s ship . Behind the scenes . The rescue of Adi Gallia was created for the and was featured in the episode " Nomad Droids , " which aired on October 14 , 2011 . Because of a lack of information presented in the episode , a specific location for the battle cannot be determined beyond being in space .
