Vojislav Lukačević Vojislav Lukačević ( Serbian Cyrillic : Војислав Лукачевић ; 190814 August 1945 ) was a Serbian Chetnik commander in the Kingdom of Yugoslavia during World War II . At the outbreak of war , he held the rank of captain of the reserves in the Royal Yugoslav Army . When the Axis powers invaded Yugoslavia in April 1941 , Lukačević became a leader of Chetniks in the Sandžak region and joined the movement of Draža Mihailović . While the Chetniks were an anti - Axis movement in their long - range goals and did engage in marginal resistance activities for limited periods , they also pursued almost throughout the war a tactical or selective collaboration with the occupation authorities against the Yugoslav Partisans . They engaged in cooperation with the Axis powers to one degree or another by establishing " modi vivendi " or operating as auxiliary forces under Axis control . Lukačević himself collaborated extensively with the Italians and the Germans in actions against the Yugoslav Partisans until mid - 1944 . In January and February 1943 , while under the overall command of Major Pavle Đurišić , Captain Lukačević and his Chetniks participated in several massacres of the Muslim population of Bosnia , Herzegovina and the Sandžak . Immediately after this , Lukačević and his Chetniks participated in one of the largest Axis anti - Partisan operations of the war , Case White , where they fought alongside Italian , German and Croatian ( NDH ) troops . The following November , Lukačević concluded a formal collaboration agreement with the Germans and participated in a further anti - Partisan offensive , Operation Kugelblitz . In February 1944 , Lukačević travelled to London to represent Mihailović at the wedding of King Peter of Yugoslavia . After returning to Yugoslavia in mid - 1944 , and in anticipation of an Allied landing on the Yugoslav coast , he decided to break with Mihailović and fight the Germans , but this was short - lived , as he was captured by the Partisans a few months later . After the war he was tried and sentenced to death , and was executed in August 1945 . Early life . Lukačević was born in 1908 in Belgrade , Kingdom of Serbia to a wealthy banking family . He attended the military academy and attained the rank of captain in the reserves of the Royal Yugoslav Army prior to the war . Invasion and occupation . After the outbreak of World War II , the government of Regent Prince Paul of Yugoslavia declared its neutrality . Despite this , and with the aim of securing his southern flank for the pending attack on the Soviet Union , Adolf Hitler began placing heavy pressure on the Kingdom of Yugoslavia to sign the Tripartite Pact and join the Axis . After some delay , the Yugoslav government conditionally signed the Pact on 25 March 1941 . Two days later a bloodless coup d ' état deposed Prince Paul and declared 17 year old Prince Peter II of Yugoslavia of age . Following the subsequent German - led invasion of Yugoslavia and the Yugoslav capitulation 11 days later , Lukačević went into hiding in the forests . He soon returned to Belgrade , where he became aware of the activities of Draža Mihailović . He then left the capital with some other officers and soldiers to form a Chetnik detachment in the Novi Pazar area of the Sandžak region . In the summer of 1942 , Lukačević and his Chetniks fought the Partisans in Herzegovina . Massacres of Muslims . In early February 1943 , during their advance northwest into Herzegovina in preparation for their involvement in Case White , Lukačević and his 1 , 600 Chetniks were placed under the overall command of Montenegrin Chetnik commander Major Pavle Đurišić after he received orders to conduct " cleansing actions " against Muslims . The combined Chetnik force of around 6 , 000 troops massacred large numbers of the Muslim population in the area surrounding Pljevlja in the Sandžak , and around Čajniče and Foča in Bosnia . In a report to Mihailović dated 13 February 1943 , Đurišić reported that the Chetnik forces under his command had killed about 1 , 200 Muslim combatants and about 8 , 000 old people , women , and children , and destroyed all property except for livestock , grain and hay , which they had seized . Đurišić reported that : Case White . Lukačević and his Chetniks were drawn into closer collaboration with the Axis during the second phase of Case White , which took place in the Neretva and Rama river valleys in late February 1943 and was one of the largest anti - Partisan offensives of the war . Despite the fact that the Chetniks were an anti - Axis movement in their long - range goals and did engage in marginal resistance activities for limited periods , their involvement in Case White is one of the most significant examples of their tactical or selective collaboration with the Axis occupation forces . In this instance , the participating Chetniks received Italian logistic support and included those operating as legalized auxiliary forces under Italian control . During this offensive , between 12 , 000 and 15 , 000 Chetniks fought alongside Italian forces , and Lukačević and his Chetniks also fought alongside German and Croatian troops against the Partisans . In February 1943 , during the second phase of Case White , Lukačević and his Chetniks jointly held the town of Konjic on the Neretva river alongside Italian troops . After being reinforced by German and NDH troops and some additional Chetniks , the combined force held the town against concerted attacks by the Partisans over a seven - day period . The first attack was launched by two battalions of the 1st Proletarian Division on 19 February and was followed by repeated attacks by the 3rd Assault Division between 22 and 26 February . Unable to capture the town and its critical bridge across the Neretva , the Partisans eventually crossed the river downstream at Jablanica . The chief of staff of the Chetnik Supreme Command , Zaharije Ostojić , was aware of Lukačević ' s collaboration with the Germans and NDH troops at Konjic but , at his trial , Mihailović denied that he himself was aware of it , claiming that Ostojić controlled the communications links and kept the information from him . During the fighting at Konjic , the Germans also supplied Lukačević ' s troops with ammunition . Both Ostojić and Lukačević were highly critical of what they described as Mihailović ' s bold but reckless tactics during Case White , indicating that Mihailović was largely responsible for the Chetnik failure to hold the Partisans at the Neretva . In September 1943 , immediately following the Italian capitulation , the Italian Venezia Division , which was garrisoned at Berane , surrendered to the British Special Operations Executive Colonel S . W . " Bill " Bailey and Major Lukačević , but Lukačević and his troops were unable to control the surrendered Italians . Partisan formations arrived in Berane shortly afterward and were able to convince the Italians to join them . Collaboration with the Germans . In September 1943 , United States Lieutenant Colonel Albert B . Seitz and Lieutenant George Musulin parachuted into the Territory of the Military Commander in Serbia , along with British Brigadier Charles Armstrong . In November , Seitz and another American liaison officer , Captain Walter R . Mansfield , conducted a tour of inspection of Chetnik areas , including that of Lukačević . During their tour they witnessed fighting between Chetniks and Partisans . Due to their relative freedom of movement , the Americans assumed that the Chetniks controlled the territory they moved through . However , despite the praise that Seitz expressed for Lukačević , the Chetnik leader was collaborating with the Germans at the same time that he was hosting the visiting Americans . In mid - November 1943 , Major Lukačević was the chief of the Chetnik detachments based near Stari Ras , near Novi Pazar in the Sandžak . On 13 November , his representative concluded a formal collaboration agreement ( ) with the representative of the German Military Commander in southeast Europe , " General der Infanterie " ( Lieutenant General ) Hans Felber . The agreement was signed on 19 November , and covered a large portion of the Sandžak and the Territory of the Military Commander in Serbia , bounded by Bajina Bašta , the Drina river , the Tara river , Bijelo Polje , Rožaje , Kosovska Mitrovica , the Ibar river , Kraljevo , Čačak and Užice . Under the agreement , a special German liaison officer was assigned to Lukačević to advise on tactics , ensure cooperation , and facilitate arms and ammunition supply . British Prime Minister Winston Churchill read the decrypted text of the agreement between Lukačević and Felber , which had a significant influence on the changing attitude of the British towards Mihailović . In early December 1943 , Lukačević ' s Chetniks participated in Operation Kugelblitz , the first of a series of German operations alongside the 1st Mountain Division , 7th SS Volunteer Mountain Division Prinz Eugen , and parts of the 187th Reserve Division , the 369th ( Croatian ) Infantry Division and the 24th Bulgarian Division . The Partisans avoided decisive engagement and the operation concluded on 18 December . Also during December , the Higher SS and Police Leader in the Sandžak , " SS - Standartenführer " Karl von Krempler , posted notices authorising local Serbs to join Lukačević ' s Chetniks . On 22 December , shortly after the conclusion of Operation Kugelblitz , " Oberst " ( Colonel ) Josef Remold issued an order of the day commending Lukačević for his enthusiasm in fighting the Partisans in the Sandžak , and allowed him to keep some of the arms he had captured . Break with Mihailović . In February 1944 , Lukačević and two other Chetnik officers accompanied Bailey to the coast south of Dubrovnik and were evacuated from Cavtat by a Royal Navy gunboat . Their passage through German - occupied territory was probably facilitated by Lukačević ' s accommodation with the Germans . At one point he was invited to have a meal with the German garrison commander of a nearby town , but did not accept . Lukačević then travelled via Cairo to London , where he represented Mihailović at King Peter ' s wedding on 20 March 1944 . After the British government decided to withdraw support from Mihailović in 1944 , Lukačević was not permitted to return to Yugoslavia until the British mission to Mihailović headed by Armstrong had been safely evacuated from occupied territory . Lukačević flew out of Bari in Italy into an improvised airfield at Prajani northwest of Čačak on 30 May 1944 . However , before he left Italy he and his companion were relieved of uncensored letters , gold and jewellery that had been stolen from the Yugoslav Government office in Cairo a short time before . In mid - 1944 , after Mihailović was removed from his post as Minister of the Army , Navy and Air Force as a result of the dismissal of the Purić government by King Peter , Lukačević attempted to independently contact the Allies in Italy in the hope of " reaching an understanding on a common fight against the enemy " . When these attempts failed , in August 1944 Lukačević announced that he and other Chetnik commanders in eastern Bosnia , eastern Herzegovina and Sandžak were no longer obeying orders from Mihailović , and were forming an independent resistance movement to fight the occupiers and those collaborating with them . On 19 October he proposed that the Chetniks change their policy to greet the Red Army as liberators and ask to be taken under the command of a Russian general . He also tried to arrange a non - aggression pact with the Partisans . In early September he issued a proclamation to the people explaining his reasons for attacking the Germans . Subsequently , he deployed his 4 , 500 Chetniks into southern Herzegovina and for several days from 22 September they attacked the 369th ( Croatian ) Infantry Division and the Trebinje - Dubrovnik railway line , capturing some villages and taking hundreds of prisoners . Mihailović formally relieved Lukačević of his command and asked other Chetnik commanders to act against him . However , the Partisans , concerned Lukačević was trying to link up with a feared British landing on the Adriatic coast , attacked his forces on 25 September , first capturing his stronghold at Bileća and then comprehensively defeating him . With several hundred remaining Chetniks , Lukačević withdrew as far as Foča before returning to the Bileća area in the hope of linking up with small detachments of British troops that had been landed to support Partisan operations . Instead he was captured by the Partisans . Trial and execution . Lukačević , along with other defendants , was tried by a military court in Belgrade between 28 July and 9 August 1945 . He was accused of conducting the massacre at Foča , participating in the extermination of the Muslim population , collaboration with the occupying forces and the Serbian puppet government of General Milan Nedić and the commission of crimes against the Partisans . He was found guilty of various offences and executed by firing squad on 14 August 1945 .
