The Bleiburg Tragedy is named after the town of Bleiburg, Austria, the location of a post-World War Two surrender of Croatian refugees to the Communist Yugoslav Army. This exclusively Croatian surrender on 15 May 1945 was distinct from other surrenders in post-war Austria. The surrender negotiations are the main focus of this book. Although the Yugoslav officer guaranteed to treat the unarmed Croatian soldiers and civilians according to international law this promise was broken. Inside Yugoslavia over half a million unarmed Croats were sent on Death Marches and massacred. British, American, Croatian and Yugoslav sources are compared and contrasted to determine how and why this happened. For example, the Communist Bulgarian Army's refusal to allow the main columns of retreating Croats to cross the Drava River is exposed. The Bulgarians re-routed some of the columns towards Poljana, where they were attacked by Yugoslavs and eventually surrounded at Bleiburg. In addition, the Bulgarians also handed many of the other retreating Croatian columns to the Yugoslavs who sent them back towards Maribor on Death Marches. Tito's betrayal of his western Allies is revealed in the context of a bloody Bolshevik revolution - his consolidation of power included the strong Yugoslav occupation of southern Carinthia, Austria, and the liquidation of his Croatian opposition, and other smaller repatriated anti-Communist groups, inside Yugoslavia. Top ranking Serbian cadres in Communist Yugoslavia acknowledged the crimes against humanity. For example, Djilas remarked that Croats had to die so that Yugoslavia could live; and Rankovic admitted that 586,000 Enemies of the People were liquidated. This genocide did not escape the attention of world leaders at the time. Truman remarked that Tito killed more than 400,000 of his opponents to establish himself as dictator, and according to Churchill Tito's tactics marked the beginning of the Iron Curtain. Since the end of the Cold War and violent collapse of Yugoslavia, Tito's post-World War Two genocide is slowly being re-exposed due to the discovery of hundreds of post-World War Two mass graves. No one has been held accountable for these crimes against humanity. That is why the Srebrenica genocide happened, and why it was such a shock to the world. In 2014 in the Daily Mail Online's list of the world's most murderous regimes, Tito is listed to have slaughtered 570,000 of his political opponents. Once again the ethnic identity of his
