The Battle of Anoth was a key battle in Admiral Strasbourg's first campaign against the Galactic Alliance. Although the planet Anoth had left the Galactic Alliance years before the war it still some-what associated itself with the galactic government.
In order to show that not even planet–states were immune to the Sith advance; Darth Adsec ordered the decimation of much of Anoth's surface before he began landing troops.
