Book excerpt: This book describes and illustrates French fortifications from 1715 (the death of Louis XIV) to 1815 (the fall of Napoleon), focusing particularly on the Napoleonic era. After an historical background, it covers the heritage of the Ancien Regime with the important contributions of Vauban (the bastioned defense), Gribeauval's reforms in artillery, and Montalembert's innovations. Chapters explore the style of Napoleonic fortifications, siege warfare, artillery and engineering corps, as well as the Napoleonic achievements in France, Italy, German and the Netherlands, including projects that were planned but never completed.
