How does the author use foreshadowing in The Covenant?

When the Dutch first occupy South Africa, it is with the intention of creating a shipping link and a restocking port to aid in the control of scurvy and a host of issues associated with months uninterrupted at sea. Once a fort is established, the Dutch assume ownership of a land that they consider uninhabited by civilized people. It is many years before that concept is challenged with the discovery that Zimbabwe was built by the natives and not of Phoenician origin as originally thought. This made it difficult to pursue the argument that the natives needed the Dutch to civilize them and bring them out of the dark ages. The Dutch have a strong foothold on the Cape when the next set of immigrants arrive. Calvinists from France who flee their homeland because of religious persecution find new starts in Africa, but the Dutch prefer all traces of French be left behind..... foreshadowing racial and religious disparity.
