A few months ago, YouTuber Jeffrey the Librarian released an informative video on the American Civil War, focusing on the events of July 1861. He takes a broad view of the conflict, covering developments not only in Virginia but also in Missouri. It is one of the best videos I have seen on the subject. He also has a companion video on June 1861 that is well worth watching. Check it out:
