Here’s Frank O’Reilly, the Chief Historian at the Fredericksburg and Spotsylvania National Military Park, giving an excellent presentation on the Battle of Fredericksburg.
The video’s description reads, “Historian Frank O’Reilly discussed one of the most one-sided battles of the Civil War, the first battle of Fredericksburg & Marye’s Heights. The National Museum of the Civil War Soldier in Petersburg, Virginia, hosted this event.”
