Imperial Navy Admiral Carlou Gendling's task force consisted of six ships, one of which was the Imperial-class Star Destroyer Foremost, which served as its flagship. The task force also possessed four corvettes, at least two of which were Raider-class corvettes; and one light cruiser.
The task force was assisted at Umbara by the Thunder Wasp.
During the Imperial Era, Admiral Carlou Gendling commanded a task force in the Galactic Empire. At some point, the criminal Nevil Cygni instigated an uprising on the Expansion Region planet Umbara, which aided him by allowing the Empire to seize the world's mining and refining facilities. Gendling was sent to respond to the uprising in the Formost, along with two Raider-class corvettes, while his other ships, two more corvettes and a light cruiser, were sent off to investigate a problem in another system. Aiding Gendling's ships at Umbara was the Arquitens-class light cruiser Thunder Wasp.
At Umbara, Gendling, assisted by the Arquitens-class light cruiser Thunder Wasp, fought against the rebellious Nightswan's forces, although the admiral's ships were heavily damaged, with one of the Raiders being destroyed. However, the Thunder Wasp managed to defeat the enemy vulture droids, winning the battle for the Empire.
Carlou Gendling's task force first appeared in the 2017 novel Thrawn, written by Timothy Zahn.
