Onderon insurgency

During the reign of the Galactic Empire, Saw Gerrera and his Partisans mounted an insurgency on his home planet of Onderon. The planet was severely destabilized by the conflict, leading to the Empire attempting to suppress the rebellion via the deployment of units such as Agent Kallus' platoon as well as bombing rebel-held areas.

In the end, the insurgency ended in failure for the Partisans; Gerrera came to believe they could not win the battle for his homeworld and left it.
