To write an essay about a historical event, I would do research. I would consult textbooks, the internet, and other resources that have information relevant to a historical event that I am writing an essay on. To write an informative essay about a historical event, I would want a strong thesis statement, and strong supporting body paragraphs. I would want the body of my essay to be full of detail and factual information from my research (which of course you want to sight :)) Additionally, I would want to use strong transition words and powerful vocabulary. Finally, I would want my essay to be engaging.
Hope this helps :)
