In the next place we have omitted all descriptions of battles. Our reasons for this are simple. The strategy of a campaign or of a single battle is a highly technical, and usually a highly controversial, matter about which experts differ widely. In the field of military and naval operations most writers and teachers of history are mere novices. To dispose of Gettysburg or the Wilderness in ten lines or ten pages is equally absurd to the serious student of military affairs. Any one who compares the ordinary textbook account of a single Civil War campaign with the account given by Ropes, for instance, will ask for no further comment. No youth called upon to serve our country in arms would think of turning to a high school manual for information about the art of warfare. The dramatic scene or episode, so useful in arousing the interest of the immature pupil, seems out of place in a book that deliberately appeals to boys and girls on the very threshold of life's serious responsibilities. It is not upon negative features, however, that we rest our case.
