The Battle of Atticus Minor was fought at Atticus Minor during the Great War.
The Sons of Korhal, led by Arcturus Mengsk, wrested the planet from the Terran Confederacy but had to deal with a zerg infestation thereafter.
Meanwhile, the Confederacy sent their outlaw team called the War Pigs to assassinate Mengsk. The War Pigs tried to use the chaos of the zerg invasion to kill Mengsk but failed and were forced to flee from the zerg. They successfully evaded the xenomorphs, only to fall afoul of a Confederate blockade. Nuura Joss evaded them as well.
