These rebels originated on the world of Yag'Dhul. Their activities in 5 BBY drew the notice of the Galactic Empire, leading to the deployment of Imperial forces, including the Imperial I-class Star Destroyer named Desolator, to engage them. The resulting conflict ended in the rebels' loss. Nevertheless, due to a distraction involving a group of bettors who were placing wagers on the battle—the Imperials incorrectly assumed they were providing the rebels with information—the Imperials also targeted the bettors, which created an opportunity for numerous rebel fighters to flee into faster-than-light travel.
