During the Outer Rim Sieges of the Clone Wars, a conflict took place in space in 19 BBY between the forces of the Galactic Republic and those of the Confederacy of Independent Systems. This clash occurred following the commencement of a large offensive across the Outer Rim Territories by General Grievous, the Kaleesh Separatist Supreme Commander, resulting in the aforementioned sieges.
During this engagement, a Separatist fleet, consisting of a minimum of six Providence-class Dreadnoughts under the command of Grievous, confronted a Republic fleet composed of at least six Venator-class Star Destroyers. As Grievous observed from the bridge of one of the Providence-class vessels, manned by numerous B1-series battle droids, droid tri-fighters of the Separatists and Clone Z-95 Headhunters engaged in aerial dogfights surrounding the capital ships. At least two of the dreadnoughts suffered substantial damage to their hulls.
The confrontation between the Republic and Separatist fleets was featured in the introductory newsreel of "Old Friends Not Forgotten," the ninth episode in the seventh season of the Star Wars: The Clone Wars animated series, which was broadcast on April 17, 2020.
