Young men historically enlisted in wars driven by the heroic narratives they absorbed during their upbringing. They held idealistic views, believing in the glory and honor associated with battle. However, their experiences often led to profound disillusionment, particularly when the realities of war starkly contrasted with their expectations.

In Bruce Catton's "Mr. Lincoln's Army," this theme is vividly explored. The soldiers who fought in the Civil War faced harsh truths that shattered their childhood illusions. Their journey from naive enthusiasm to an understanding of the brutal realities of war was a difficult one, reflecting a deeper disenchantment than even modern soldiers might experience.
