On the one-year anniversary of "The Antietam And Beyond Podcast," longtime National Park Service ranger Keith B. Snyder — chief of resource education at the battlefield — visits with co-hosts Tom McMillan and John Banks about the new Antietam movie to be shown to public for the first time on Veterans Day and educates us about U.S. Marines Corps' exercises on the field in 1924. Plus, he talks about his famous "battlefield in a box" and much more.

The podcast is sponsored by Civil War Trails, which since 1994 has connected visitors with small towns and big stories across a network that now spans six states.

Join McMillan and Banks for regular podcasts about Antietam, the Maryland Campaign and the Civil War — the most compelling period in American history.

McMillan is author of Our Flag Was Still There and other books. Banks is author of A Civil War Road Trip Of A Lifetime. Find them on Facebook at Author Tom McMillan and John Banks' Civil War Blog. Banks' popular Civil War blog is here.
