Histoire du Consulat et de l'Empire, (Vol. 20/20) / faisant suite à l'Histoire de la Révolution Française

The volume offers a detailed military account of the 1815 campaign culminating at Waterloo, tracing initial concentrations, operational plans, and the separate engagements at Ligny and Quatre-Bras. It analyzes commanders' decisions and hesitations, the timing and impact of marches, the role of weather and terrain, and the coordination or failure between the French, Prussian, and Anglo-allied forces. Descriptions cover maneuvers to interpose forces between enemies, the pursuit and retreats after battle, and the controversial detachment under Grouchy. The narrative emphasizes how command choices, communication, and timing shaped the decisive encounter on the Mont-Saint-Jean plateau.
