A detailed narrative and analysis of the great battle fought near Mont-Saint-Jean, presenting troop movements, command decisions, and the shifting fortunes of both sides while stressing the irreconcilable eyewitness testimonies that have obscured a definitive account. The author reconstructs strategic dispositions, tactical errors, logistical privations, and critical turning points, evaluates official reports and personal memoirs, and dispels popular myths propagated by literature and art. Chapters blend campaign chronology with critical commentary and a concluding supplementary chapter.
