The Kočevski Rog massacre was a series of massacres near Kočevski Rog in late May 1945 in which thousands of members of the Nazi Germany–allied Slovene Home Guard were executed, without formal charges or trial, by special units of the Yugoslav Partisans; other victims were Croat, Serb and Montenegrin collaborationists as well as much smaller numbers of Italian and German troops.

[1] After the armistice, the British repatriated more than 10,000 Slovene collaborators who had attempted to retreat with the Germans; Josip Broz Tito had most of them massacred at the infamous pits of Kočevje.

Most of these prisoners of war who were repatriated by the British military authorities from Austria, where they had fled, died in these post-war summary executions.

[7] In his 1958 book Kočevje: Tito's Bloodiest Crime, Borivoje Karapandžić, a publicist and World War II propaganda chief for the Serbian fascist, anti-Semitic and Nazi-collaborationist Zbor organization of Dimitrije Ljotić,[8] estimated the total number of victims at about 18,500: 12,000 Slovene Home Guard, 3,000 Serbian volunteer troops, 2,500 Croatian Home Guard and 1,000 Montenegrin chetniks.

[9] Karapandžić's evaluation is reported in another newer book printed in Slovene and Italian by a group of scholars.
