The justification for these assertions is to be found in the history of the principal German colonies. In the Cameroons the native tribes, who had been so ready to receive European government that they had repeatedly asked for British protection, were driven to such incessant revolts that the annals of the colony seem to be annals of continuous bloodshed: forty-six punitive expeditions were chronicled in the seventeen years from 1891--long after the establishment of the German supremacy, which took place in 1884. The record of East Africa was even more terrible for the ferocity with which constant revolts were suppressed. But worst of all was the story of South-West Africa. There were endless wars against the various tribes; but they culminated in the hideous Herero war of 1903-6. The Hereros, driven to desperation by maltreatment, had revolted and killed some white farmers. They were punished by an almost complete annihilation. The spirit of this hideous slaughter is sufficiently expressed by the proclamation of the governor, General von Trotha, in 1904. 'The Herero people must now leave the land. Within the German frontier every Herero, with or without weapon, with or without cattle, will be shot. I shall take charge of no more women and children, but shall drive them back to their people, or let them be shot at.' Ten thousand of these unhappy people, mainly old men, women and children, were driven into the desert, where they perished. There is no such atrocious episode in the history of European imperialism since Pizarro's slaughter of the Incas; if even that can be compared with it.
