“Not a condensation of the author’s three volumes on the Civil war in his ‘History of the United States’ but a fresh study which makes use of the large amount of material on that period which has come to light in recent years. Good maps and an index are included with the text.” Book Review Digest
“The student of war politics and of midcentury American diplomacy will find much to interest him in several of the chapters, for the volume is not, as its title might imply, a mere narrative of military operations. It is a discussion of national life in all its phases during a great and critical period of American history.” American Political Science Review
