The Imperial Third Fleet consisted of various vessels of war. These were part of the Navy belonging to the reconstituted Sith Empire, and they were sent into battle during the Great Galactic War. In the war's concluding years, this fleet suffered a defeat at the hands of Admiral Zale Barrows of the Galactic Republic. Barrows, a privateer officer who commanded the Free Spacers Fleet, achieved this victory above the planet of Dantooine.
