In a freewheeling discussion, Dana Shoaf talks with co-hosts (and fellow Pittsburghers) Tom McMillan and John Banks about Dr. Jonathan Letterman, medical services at Antietam, Civil War ambulances and the National Museum of Civil War Medicine in Frederick, Md., where he serves as director of interpretation. Shoaf, the former editor for Civil War Times magazine (R.I.P.), lives near the South Mountain (Md.) battlefields, where he occasionally hears the boom of reenactors' cannon.

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.
