This work outlines lessons from the past that are relevant to today's conflicts and focuses on French military actions against counterinsurgents during the 1940's and 50's. This revised and updated edition is part of the highly acclaimed "Praeger Security International Classics of Counterinsurgency" series, and now features both the original introduction by Bernard Fall, and a new foreword by Eliot Cohen. "Modern Warfare" reveals how the French military fought fierce rearguard actions against ideologically motivated insurgents in Indochina during the 1940's and 1950's, to much greater extent than the Americans ever did in the later Vietnam conflict. In focusing on this lesser-known phase in the build up to American involvement in Vietnam, it outlines important lessons in the understanding of counterinsurgency movements that are relevant to today's conflicts.
