An old friend of mine has co-written a book, The Big Divide: A Travel Guide to Historic and Civil War Sites in the Missouri-Kansas Border Region. According to their Amazon page, inside they cover “the African-American soldiers who were the first to die for their freedom (months before the 54th Massachusetts of Glory fame took up arms) and “how the Civil War shaped future outlaw Jesse James—and future president Harry Truman.”
Here they are, on public radio, to tell you about it themselves!
