"Destined to be the classic account of what may be the oldest ... hardest form of war."-John Nagl, Wall Street Journal

Invisible Armies presents an entirely original narrative of warfare, which demonstrates that, far from the exception, loosely organized partisan or guerrilla
warfare has been the dominant form of military conflict throughout history. New York Times best-selling author and military historian Max Boot traces guerrilla
warfare and terrorism from antiquity to the present, narrating nearly thirty centuries of unconventional military conflicts. Filled with dramatic analysis of strategy and tactics, as well as many memorable characters-from Italian nationalist Guiseppe Garibaldi to the "Quiet American," Edward Lansdale-Invisible Armies is "as readable as a novel" (Michael Korda, Daily Beast) and "a timely reminder to politicians and generals of the hard-earned lessons of history" (Economist).
