The defeat of South Vietnam was arguably America's worst foreign policy disaster of the twentieth century. Yet a complete understanding of the endgame—from the January 27, 1973 signing of the Paris Peace Accords to South Vietnam's surrender on April 30, 1975—has eluded us.

Black April addresses that deficit. A culmination of exhaustive research in three distinct areas: primary source documents from American archives, North Vietnamese publications containing primary and secondary source material, and dozens of articles and numerous interviews with key South Vietnamese participants, this book represents one of the largest Vietnamese translation projects ever accomplished, including almost one hundred rarely or never seen before North Vietnamese unit histories, battle studies, and memoirs. Most important, to celebrate the thirtieth anniversary of South Vietnam's conquest, the leaders in Hanoi released several compendiums of formerly highly classified cables and memorandum between the Politburo and its military commanders in the south. This treasure trove of primary source materials provides the most complete insight into North Vietnamese decision-making ever complied. While South Vietnamese deliberations remain less clear, enough material exists to provide a decent overview.
