An exceptional and perceptive Civil War officer, John Henry Stover Funk trained as a physician and frequently tended to wounded soldiers. Yet he deliberately chose the path of combat leadership, beginning his service as a captain in the 5th Virginia Infantry. His diary captures the texture of life as a volunteer soldier, the increasingly bloody fighting in the Eastern Theater, and the deep political and social rifts that would eventually give rise to the separate state of West Virginia.

Funk's service coincided with the Shenandoah Valley Campaign, a pivotal Confederate effort to control a vital agricultural corridor and divert Federal forces from Richmond. He witnessed firsthand the rise of Thomas "Stonewall" Jackson, including the moment when Jackson earned his famous nickname for his resolve under fire. His diary is the only firsthand account of the event. Funk traces the growth of Jackson's reputation as both an inspired tactician and a demanding, enigmatic leader.

Throughout the memoir, Funk reflects on the decisions of Lee, Jackson, and Johnston, examining how those choices affected officers and enlisted men. Funk died at the Battle of Winchester in 1864 but left a record that blends medical compassion, military duty, and sharp historical insight.
