As this month marks the 149th anniversary of the Battle of Fredericksburg, here is a video of my talk on the 123rd Pennsylvania Volunteers' experience in that engagement. This lecture was presented back in April for the 2011 Civil War Weekend at the Carnegie Library and Music Hall in Pittsburgh, PA. On a related note, I have just agreed to lead the 2012 Staff Ride at the Fredericksburg Battlefield for the senior staff here at the U.S. Marshals Service. More on that later.
