The concluding engagement of the Galactic Republic's campaign against the Valahari contingent of the Confederacy of Independent Systems during the Clone Wars was the Battle of the Veil Nebula.
During the Battle of the Hexus system, Anakin Skywalker affixed a homing beacon to the starfighter Tempest Zero piloted by Tofen Vane. This allowed the Republic to locate the Harko Station within the Veil Nebula which served as his base. A substantial Republic task force was dispatched to obliterate the base, where V-19 Torrent starfighters from the Gold Squadron, Delta-7B Aethersprite-class light interceptors piloted by Jedi Master Plo Koon and Saesee Tiin, along with Skywalker's Eta-2 Actis-class interceptor prototype, engaged the enemy starfighters, while Venator-class Star Destroyers bombarded the station. In the midst of the battle, the Valahari initiated a transmission that emulated a nesting neebray brood mother. This caused the local neebrays to launch an assault on the Republic forces. However, the BTL-B Y-wing starfighters of the Shadow Squadron successfully destroyed the station, thereby halting the transmission. Tofen Vane, the leader of Tofen's Raiders, was killed in aerial combat by Skywalker.
