The Undaunted was a gunship present in the Cularin system during the execution of Order 66 in 19 BBY, at the end of the Clone Wars. Along with the Primal, another Republic warship, it attacked Jedi starships that were attempting to flee from the planet Almas. However, while carrying out their duties, the Undaunted and the Primal were attacked by the Maelstrom, another Republic capital ship. The Maelstrom was commanded by Jedi Master Darrus Jeht, who had evaded death during Order 66 by preventing his crew from learning of the order, and he deceived his crew into believing that the Primal and the Undaunted had been taken over by the Confederacy of Independent Systems.
Jeht was victorious in the engagement and both the Primal and the Undaunted were destroyed.
