The sentence that I highlighted the growth of colonial settlements into powerful self-sustaining places. The statement "warring against the Native American" refers to the constant conflict between the European settlers and the indigenous people which often fought over land and resources. This reflects the mindset of colonist who viewed the land as their own prior to the Native American being there before them.
