First and only edition of a work on modern French fortification by Lieutenant-Colonel Rozard. He states in his preface that, even though there are many books on fortification, most still present outdated methods, and he tries to present a modern method of fortification, both theoretical and practical. He does, however, include some 17th-century methods as described by Simon Stevin and Blaise Francois Pagan. Other chapters deal with more modern engineers like Vauban and Manesson Mallet. The second part describes how to construct different types of fortresses (square, pentagon, hexagon, irregular, etc.) and the interior of a fortress. The atlas volume contains many ground plans and profiles.
