The atrocities and horrors perpetrated by the Nazi's and Japanese are well known and documented. Equally abhorrent, but far less well known, are the barbaric actions committed by the Allies, particularly in the aftermath of the war when power was being consolidated and centralized by the new Eastern European regimes. In Yugoslavia, the anti-communist Croat population became the victims of one of the most vicious peacetime purges in the annals of western civilization. Operation Slaughterhouse relates, through a series of eyewitness accounts, the horrible suffering of the entire Croatian nation endured at the hands of Yugoslav Partisans. The widespread and indiscriminate slaughter of hundreds of thousands of innocents marks the history of then Communist-dominated Yugoslavia, whose rivers and fields were tainted by mutilated Croatian corpses, both military and civilian. That these genocidal horrors went on without a world-wide outcry of protest is largely that the Americans were unaware of these horrors because the postwar Western press was only concerned with the ignominy of its conquered adversaries—and because the victors in any war are never accused of committing "atrocities." Operation Slaughterhouse is a monument of testimony to those voiceless times and forgotten victims—and an antidote to the observation that those who forget history, are themselves doomed to repeat it.—Midwest Book Review
