This work investigates the efficacy of supreme command during the First World War by analyzing the leadership styles and strategic decisions of six prominent military figures. Correlli Barnett, a noted military historian, examines the interplay between individual personality, institutional constraints, and the evolving nature of industrial warfare. By evaluating the performance of commanders from both the Allied and Central Powers, the author argues that the outcome of the conflict was heavily influenced by the intellectual and administrative limitations of those in positions of supreme authority.

Military historians frequently cite this work as a critical examination of the human element in high-level strategic failure and success. Scholars often note the author's rigorous, critical approach to evaluating the reputations of these commanders within the context of twentieth-century warfare.
