On Episode 29, Chris Bryan — author of Cedar Mountain to Antietam: A Civil War Campaign History of the Union XII Corps, July-September 1862 — dives deep into the corps' role at Antietam with co-hosts Tom McMillan and John Banks. Bryan dishes on General Joseph Mansfield, right flank-left flank aspects of the fighting on Sept. 17, 1862, and on his dog, Harlon Boone.
