Finally, in April and May 1945, as the victorious Partisans took possession of the country's territory, many Chetniks retreated toward Italy and a smaller group toward Austria. Many were captured by the Partisans or returned to Yugoslavia by British forces while a number were killed following repatriation from Bleiburg. Some were tried for treason and were sentenced to prison terms or death. Many were summarily executed, especially in the first months after the end of the war. Mihailović and his few remaining followers tried to fight their way back to the Ravna Gora, but he was captured by Partisan forces. In March 1946, Mihailović was brought to Belgrade, where he was tried and executed on charges of treason in July. During the closing years of World War II, many Chetniks defected from their units, as the Partisan commander-in-chief, Marshal Josip Broz Tito, proclaimed a general amnesty to all defecting forces for a time. After the end of WWII Yugoslav authority undertook radical actions to destroy remaining Chetnik groups, especially in Lika area. One of the radical methods was forced displacement of Serbs from the area of Gospić, Plaški, Donji Lapac and Gračac. Chetnik attacks on villages were recorded in June 1945, as it were attack on Dobroselo. The main part of the Chetniks was located in the area of Lapac while in the winter of 1946 actions were organized against them which testifies about the seriousness of the Chetnik threat.
