Book excerpt: In 1967, the North Vietnamese launched a series of offensives in the Central Highlands along the border with South Vietnam--a strategic move intended to draw U.S. and South Vietnamese forces away from major cities before the Tet Offensive. A series of bloody engagements known as "the border battles" followed, with the principle action taking place at Dak To. Drawing on the writings of key figures, veterans' memoirs and the author's records from two tours in Vietnam, this book merges official history with the recollections of those who were there, revealing previously unpublished details of these decisive battles.
