Bierce employed a distinctive style of writing, especially in his brief stories. His style often embraces an abrupt beginning, dark imagery, vague references to time, limited descriptions, impossible events and the theme of war. In 1913, Bierce traveled to Mexico to gain first-hand experience of the Mexican Revolution. While traveling with rebel troops disappeared in Mexico in 1914 without a trace and his final fate is unknown. A "Diagnosis of Death" by Ambrose Bierce is cryptic and mysterious short story with an implication of uncertainty and lack of proof.
