Book excerpt: In "Why the South Lost the Civil War," four historians considered the dominant explanations of southern defeat. At end, the authors found that states' rights disputes, the Union blockade, and inadequate southern forces did not fully account for the surrender. Rather, they concluded, the South lacked the will to win. Its strength sapped by a faltering Confederate nationalism and weakened by a peculiar brand of evangelical Protestantism, the South withdrew from a war not yet lost on the field of battle. Roughly one-half the size of its parent study, "The Elements of Confederate Defeat" retains all the essential arguments of the earlier edition, forming for the student a book that at once follows the events of the war and presents the major interpretations of its outcome in the South.
