The Conquest of Halka

Halka, a pacifist world with a primitive native population, is bombarded and annexed by the Galactic Empire. The Halkans had valuable mineral resources, but refused to extract this and had denied the Imperial demands for mineral access. They paid for this decision for their lives, as nearly all of the world's 1.1 billion population was exterminated. The remaining Halkans were deported by the Empire, which established massive mining operations, processing lines, automated plants, and collection shipyards on the world.
