 It was a while ago, but he's an expert. So if you get an opportunity to take a class with him, take a class. So we are going to continue to discuss the Civil War. Thankfully for Dr. Kynard, we get to look at the aspect of weaponry and its impact on the war. So without further ado, I will hand the class over to Dr. Kynard. Well, thank you, Dr. Bartee.
