Mission to Skytop Station

During the Clone Wars, Galactic Republic military personnel carried out a mission to Skytop Station. The Republic had deduced that the Confederacy of Independent Systems was operating a secret listening post to spy on their transmissions, and eventually, thanks to a transmission from Jedi Knight Anakin Skywalker's recently captured astromech droid R2-D2, located the post, Skytop Station, on a moon in the Ruusan system.

Skywalker, his Padawan Ahsoka Tano, and a squad of clone troopers led by Captain Rex snuck into the station on orders from Jedi General and Master Obi-Wan Kenobi to destroy the station. Skywalker also wanted to rescue R2, whom Kenobi had been appalled to discover had never been memory-wiped. The mission was complicated when it was discovered that the astromech assigned to replace R2, R3-S6, was a Separatist spy. Eventually, Skytop Station was destroyed, with Skywalker, Tano, and the surviving clones escaping in the Twilight, and Skywalker popping back in his starfighter to rescue R2 from the plummeting station. General Grievous, who had been present at the station, also escaped in his ship, the Soulless One.
