Here’s the always excellent and always entertaining Ranger Matt Atkinson giving a lecture on Fitz-John Porter’s court-martial as part of the 2017 Gettysburg National Military Park Winter Lecture Series. This is a terrific presentation.
The video’s description reads, “After the Battle of Second Manassas, Porter garnered much of the blame for the defeat. He was subsequently court martialed and cashiered for his conduct during the battle. He spent the next 25 years trying to exonerate his name.”
