The plowing of ground and fence-building by the Dutch was to the natives a declaration of war upon the rights of Africans--that is, according to the natives themselves, just as the building and mining by the British in the Transvaal is held to be hostile by the Boers who have inherited Hottentot principles with their Hottentot blood. In 1659 Van Riebeck, of Cape Town, wrote to the Governor-General at Batavia that the natives had been in mischief again, that one prisoner spoke "tolerable Dutch," and "being asked why they did us this injury, he declared ... because they saw that we were breaking up the best land and grass, where their cattle were accustomed to graze, trying to establish ourselves everywhere, with houses and farms, as if we were never more to remove, but designed to take, for our permanent occupation, more and more of this Cape Country, which had belonged to them from time immemorial." [Sidenote: Wars with the Natives] Wars with the natives were frequent. The first one with the Hottentots occurred in 1659, and arose out of the natives finding their cattle debarred from accustomed pasture lands. It consisted chiefly in a series of cattle raids and fruitless return expeditions, but was perhaps as annoying as a more real war would have been. The Hottentot tribes could never be found when sought for by the Colonists, and no doubt this mobility on the part of their earliest enemy gave the Dutch settlers lessons from which they profited during the succeeding two hundred years. The last important struggle with this native race was in 1673, and arose out of the destruction by Dutch hunters of antelopes, elephants and other game which were very precious to the Hottentot, and were within the territories of the principal remaining tribe--the Cochoqua. During four years a sort of guerilla war was carried on with Gonnema, the Chief of the clan, and considerable loss of cattle, some loss of life and a great loss of sleep caused to the border settlers before peace was concluded. Their expeditions could never get at Gonnema, although he became eventually tired of living a hunted life in the mountains, moving from hiding-place to hiding-place to escape his pursuers. Gradually, however, the Hottentots disappeared from view, so far as any measure of organized hostility was concerned, and, like the Bushmen, became either wandering pariahs of the veldt or bondsmen in the fields of their fathers.
