Raimondo Montecuccoli
The Austrian general of Italian origin Raimondo Montecuccoli (1609–1680) in his classic work on military affairs described methods of destruction and countering of enemy saps. In his paper on "the assaulting of fortresses" Vauban (1633–1707) the creator of the French School of Fortification gave a theory of mine attack and how to calculate various saps and the amount of gunpowder needed for explosions.
