Good evening.
Well, as to the first, you should probably write a narrative essay. This is an essay that tells a story about an event, occurrence, or situation from a participant's point of view. You should choose an event (or create one) and place yourself in the middle of it. Your conclusion would be the the end of the event and how it "turned out."
The point of narration, because this assignment specifies it, should be first person. That doesn't mean it has to be in present tense, just first person. A narrative essay should be written in first person.
Your instructor is requiring you to write a piece of historical fiction. Authors such as Sir Walter Scott have done wonderful things with this genre, and could probably provide you with some great examples of "historical imagination." Making up fictitious situations, characters, and events that take place during historically accurate backdrops.
I hope this helps you.
