In the final days of World War II in Yugoslavia, units of the Partisans were responsible for atrocities after the repatriations of Bleiburg, and accusations of culpability were later raised at the Yugoslav leadership under Tito. At the time, Josip Broz Tito repeatedly issued calls for surrender to the retreating column, offering amnesty and attempting to avoid a disorderly surrender. On 14 May he dispatched a telegram to the supreme headquarters Slovene Partisan Army prohibiting "in the sternest language" the execution of prisoners of war and commanding the transfer of the possible suspects to a military court.
