This is Dr. Mark DePue of the Abraham Lincoln Presidential Library and Museum discussing the Battle of Chancellorsville. Here’s what the video’s description says: “When Union forces clashed with a much smaller Confederate army in the Battle of Chancellorsville, Robert E. Lee seized victory with what many consider to be his strategic masterpiece. But Lee also paid a terrible price, as this presentation from May 2, 2013 at the Abraham Lincoln Presidential Library and Museum explains.
“Dr. Mark DePue, historian and director of the library’s Oral History Program, will discusses the battle in a PowerPoint presentation, using quotes from Civil War veterans, maps, photographs and illustrations.”
