Niccolò Machiavelli’s The Art of War — Book 6 (of 7), unabridged audiobook. Fabrizio Colonna examines siegecraft and city defense: the design and siting of fortifications, bastions and ditches, supply and relief, countermines, sorties, and the disciplined coordination of artillery, engineers, and infantry. He weighs when to assault, starve, or negotiate, highlighting prudence, patience, and logistics as decisive elements in protracted war. Produced with clear narration, even levels, and precise section markers—ideal for students of military theory, political philosophy, and Renaissance warfare.
