Fitz John Porter
His principal work is an unfinished "Story of the Civil War", to which he devoted most of his later years; this covers the years 1861-62. "The Army under Pope" is a detailed narration of the Virginia campaign of August–September 1862, which played a great part in reversing contemporary judgment on the events of those operations, notably as regards the unjustly-condemned General Fitz John Porter. Outside America, Ropes is known chiefly as the author of "The Campaign of Waterloo", which is one of the standard works on the subject.
