First system

The first system of Vauban consisted of using the theories of his predecessor, Blaise de Pagan, coherently by setting up a system of bastions which mutually protected each other. Each face of the structure was protected from enemy fire by the neighbouring bastion. Many examples of this type of system are still well preserved today, such as the earth fronts of Saint Martin de Ré and Blaye, or the northern fronts of Mont Dauphin and Mont Louis.
