Answer:
Describe to the reader a brave act by a historical figure
Explanation:
In the given excerpt, the author tells us about a heroic act of general Benedict Arnold, an important figure in the Revolutionary War. The purpose is not to show us how dangerous or heroic it is to question orders. Sometimes it is dangerous (like in this case), but sometimes it's not. The act of challenging orders is not heroic on its own, although, in this case, it turned out to be. There are some details showing us how violent the Revolutionary War was, but that is also not the point. All of these details are a part of Arnold's brave act.
