In Episode 3 of "The Antietam and Beyond Podcast," historian and author Alex Rossino joins co-hosts Tom McMillan and John Banks for an in-depth discussion of Special Order 191, the (in)famous and controversial "Lost Order."  U.S. Army soldiers discovered the orders  — issued by Army of Northern Virginia commander Robert E. Lee on Sept. 9, 1862, during the Maryland Campaign — wrapped in an envelope with cigars near Frederick, Md.

Of course, no discussion of Special Order 191 is complete without a look at George McClellan's generalship during the campaign, which culminated with battles at Antietam and Shepherdstown. We discuss "Little Mac" and go deep into Civil War "nerd-om" with Rossino, who tells us where he believes the U.S. soldiers discovered the orders. Plus, restaurant reviews and much more!

Rossino is author of three non-fiction books on the Maryland Campaign, The Tale Untwisted, Calamity At Frederickand Their Maryland. (Read his recently launched Campaign Minutes blog.)
