Book excerpt: A man of inventiveness, versatility and reformist ideas, Marshal Sebastien Le Preste de Vauban built a formidable ring of fortresses to protect France's national frontiers. More than just a fortification designer, Vauban was also a gifted economist, author, and political strategist. This book tells the complete story of Vauban's exceptional career, placing him within the framework of Louis XIV's reign and revealing his lasting influences in France and other nations. With the aid of numerous detailed drawings, 17th century bastioned fortification, artillery, and seige warfare are described in detail. Vauban's fortifications that are still standing today are particularly highlighted.
