The narrator’s insistence on using “whom” instead of “who” is just one of many grating grammatical mistakes in every episode.
(The Rule: Who functions as a subject, while whom functions as an object. Use who when the word is performing the action. Use whom when it is receiving the action.” —WM.edu).
(When in doubt, try this simple trick: If you can replace the word with “he”’ or “’she,” use who. If you can replace it with “him” or “her,” use whom.” —Grammarly.com)
As another reviewer noted, the rhetorical questions the narrator poses, and his insistence on explaining even the simplest of words and concepts, makes an interesting subject painful to learn.
Finally, the Battle of Eutaw Springs was BEFORE the Battle of Yorktown. Eutaw Springs was the last important battle in the Carolinas, but Yorktown, which is also in the south (duh), was the last battle in the southern campaign, and it’s where Cornwallis’ surrender marked the end of the war. Let’s not rewrite history, “folks” (as the narrator likes to call his listeners). 😏
