Bonus Q&A on the Civil War Series with Scott & James

Two weeks ago we finished the 25-part series on the 10 most important battles in the Civil War. Some of you had follow-up questions. We ran a poll to so which ones were the most popular. In a recording of a live-streaming Q&A session, James and Scott answer the following questions:
How many civilians died due to battles getting close to population centers (e.g., the Gettysburg battle site is close to the town)?

What was going on with John Wilkes Booth during the Civil War?

Were people at the time aware of events like Harriett Tubman's involvement in the raid on Combahee Ferry? Did that effect public perception?

For various generals (both sides), was there any correlation between how well they did in West Point and how well they did as leaders in war?

Please describe POW camps in more detail.

What do you think about the removal of the statues and the renaming of places that have been named after Confederate soldiers?
