From the small bands of wilderness warriors who battled in 18th-century North America to the Chechen Lion, and the contemporary conflict in Chechnya, John Arquilla chronicles the deadly careers of the greatest masters of irregular warfare over the past 250 years. Their impact on events has been profound, with irregulars playing crucial roles in such epochal struggles as the Anglo-French duel for North America, the defeat of Napoleon in Spain and Russia, the American Civil War, both world wars, and the current era of terrorism. Seeing the world through the eyes of guerrillas, raiders and bandits, Arquilla has written an alternative history that provides lessons for warfare in our time that must not be ignored.
