A major (and ridiculous) theme of the book is that in April 1865 guerrilla warfare was a viable option for the Confederates, to whom we should all be grateful for surrendering instead.
That you would disagree is astonishing. The most capable tactical commanders were clearly allied with the confederacy, while the Union had the upper hand on the larger strategy that would later win the war. Given the results of other civil conflicts around the world, there is adequate evidence that our country could have just as easily gone down that path.
Of course, your viewpoint on this provides a nice example of your snobbish & sneering attitude.
