Confederacy of Independent Systems during the Clone Wars. Heavily armed with dozens of laser cannons and crewed by many battle droids, several Conqueror-class dreadnaughts were used by the Confederacy when it invaded the planet Terra Sool. At least thirty-six dreadnaughts were deployed in Terra Sool's cloudy atmosphere, fighting against the local militia and a Galactic Republic detachment sent to aid Terra Sool. Although the Conqueror-class dreadnaughts easily destroyed many of Terra Sool's militia fighters, the platforms were no match for the Jedi-led Republic task force. Using their powers of the Force and their mastery of starfighter combat, the jedi hijacked and destroyed several Conqueror-class dreadnaughts during the battle, eventually defeating the Confederates and freeing Terra Sool.
