Peter the Great

by Robert K. Massie

Once the fortress was surrounded, Vauban began a series of trenches which zigzagged ever nearer to the fortress walls. Calculating the angles with mathematical precision, Vauban placed the trenches so that defending fire from the fortress walls could scarcely touch the infantry in the trenches digging their way ever closer. Meanwhile, the besieger’s artillery fired day and night at the ramparts, silencing defending cannon, smashing holes in the parapets. When the moment of assault came, the attacking infantry stormed out of the trenches and across the ditches (which they had filled with portable fascines of tightly bound brush) and through the breaches in the pulverized walls. Few sieges, however, reached this climax. In the rigorous etiquette which governed both sides, once the defender knew that it was mathematically certain that his fortress would fall, he was free to surrender with honor; neither his own government nor the besieger expected anything less. But if, in a burst of unreasoning passion, the defender refused to surrender and the assailant was forced to go to the expense in time and lives of taking the city by storm, then, once taken, the entire city was given up to rape, sack and flames.
