Black Hawk is talking of his experience of being beaten by warfare of the white man against his people and him being imprisoned. He suggests that is the only way to try to right the wrongs the white man has visited against him ie by resisting the white man's expansion into his territories. He considers the white man to be deceitful and only friendly in order to find a way to dupe the Indian. In fact Black Hawk would probably be very happy to see how the First Nations peoples have multiplied in recent years and obtained higher education and learned how to battle the white society in the courts and with road blocks and demonstrations etc and obtain some important land claims like the Tsilqhotin one in British Columbia, Canada.
<span>When writing nonfiction, an author has far more freedom to move around from one setting to another. This is not something fiction writers can often do - if the story is located in one place, it's not easy for the author to suddenly just change the location where the story is told the way nonfiction authors can. However, nonfiction writers do not have such liberties to present conflicts, use their imagination, or change their characters the way fiction authors can.</span>
