Time and Consciousness Bierce employs a non-linear narrative structure and stream of consciousness technique to depict Farquhar's shifting sense of time as his mind races during his final moments. This innovative style was groundbreaking for its era and influenced later works of fiction.

Death and Mortality
The story grapples with the inevitability of death, particularly in the context of war. Farquhar's vivid fantasy represents a psychological coping mechanism to escape the harsh reality of his execution, underscoring humanity's desire to transcend mortality.

Dehumanization of War
Through Farquhar's dehumanizing treatment by the Union soldiers, the story critiques the brutality and injustice inherent in warfare, where human life is disregarded. This anti-war sentiment reflects Bierce's own experiences in the Civil War.
