The indigenous Montagnards, recruited into service by the American Special Forces in Vietnam’s mountain highlands, defended villages against the Viet Cong and served as rapid response forces. The Special Forces and the Montagnards—each tough, versatile, and accustomed to living in wild conditions—formed an affinity for each other. In the testimony of many veterans, their working relationship with the Montagnards, nicknamed Yards, was a bright spot in a confusing and frustrating war. The bond between America’s elite fighters and their indigenous partners has persisted into the present, but despite the best efforts of vets, the Montagnards have suffered greatly in the postwar years, at least in part because they cast their lot with the U.S. Army. In a war with more than its share of tragedies, this one is less often told but is crucial to understanding the conflict and its toll.
