While reading "Street Without Joy", by Bernard B. Fall, I stumbled upon a chapter devoted exclusively to the short, heroic, but tragic story of Groupement Mobile - G.M. - 100, a French task force in South and Central Indochina, part of the CEFEO (Corps Expéditionnaire Francais en Extreme Orient) which was made up almost entirely of Korean War veterans, supplemented by battle-hardened Cambodians and Vietnamese, and equipped with its own artillery, armor and auxiliary units. Even though its members were top-of-the-line, if not elite, regular infantry, the outfit met a disastrous end within 10 months of its activation, suffering heavy casualties from day one, in a deadly never-ending string of ambushes by the commie Viet-Minh. I knew a little about G.M. 100 before getting my hands on this superb piece of military literature, but reading about it in depth makes me wonder: Which were the causes of such a hecatomb? Did they lie beyond the battlefield, in some far away place of a world recently and rudely awakened to a new struggle, the Cold War?
