Kosta Pećanac Kosta Milovanović Pećanac ( ; 1879 – 1944 ) was a Serbian Chetnik commander ( " vojvoda " ) during the Balkan Wars , World War I and World War II . Pećanac fought on the Serbian side in both Balkan Wars and World War I , joining the forces of Kosta Vojinović during the Toplica uprising of 1917 . Between the wars he was an important leader of Chetnik veteran associations , and was known for his strong hostility to the Yugoslav Communist Party , which made him popular with conservatives such as the Yugoslav Radical Union . As president of the Chetnik Association from 1932 , he transformed the association into an aggressively partisan Serb political organisation with over half a million members . During World War II , Pećanac collaborated with both the German military administration and their Serbian puppet government in the Territory of the Military Commander in Serbia . Just before the Axis invasion of Yugoslavia in April 1941 , Pećanac was provided with funds and arms to raise guerrilla units in the southern parts of Serbia , Macedonia and the Kosovo region , and he succeeded in forming a detachment of about 300 men largely in the Toplica river valley in southern Serbia , which avoided destruction during the invasion . In the first three months after the surrender , Pećanac gathered more troops from Serb refugees fleeing Macedonia and Kosovo . However , his Chetniks fought only Albanian groups in the region , and did not engage the Germans . Following the uprising in the Territory of the Military Commander in Serbia in early July 1941 , Pećanac quickly resolved to abandon resistance against the Axis , and by the end of August had concluded agreements with the German occupation forces and the puppet government of Milan Nedić to collaborate with them and fight the communist Partisans . In July 1942 , rival Chetnik leader Draža Mihailović arranged for the Yugoslav government - in - exile to denounce Pećanac as a traitor , and his continuing collaboration with the Germans ruined what remained of the reputation he had developed in the Balkan Wars and World War I . The Germans rapidly realised that Pećanac ' s Chetniks , whose numbers had grown to 8 , 000 , were inefficient and unreliable , and even the Nedić government had no confidence in them . They were completely disbanded by March 1943 . Pećanac himself was interned by the Nedić regime for some time , and was assassinated by agents of Mihailović in May or June 1944 . Early life . Kosta Milovanović was born in a village near Dečani in 1879 , although some sources mistakenly identify him as being born in 1871 . His father Milovan was a guardian of the Visoki Dečani monastery . Pećanac ' s father and his brother Milosav fought in the Russo - Turkish War of 1877 – 1878 . In 1883 , both of his parents were killed in an attack by Albanians on the monastery . After that point , Pećanac was looked after by his uncle in the village of Đurakovac near Peć for an unknown amount of time . He arrived in Serbia in 1892 at the age of 14 and worked as a mercenary . When he was 21 , he was called up for army service and served in the engineer corps , becoming a reserve officer . He later worked with the border gendarmerie near Vranje as a corporal . Pećanac was discharged at some point for reasons unknown and later joined the Chetniks . While serving with them he was given the nickname " Pećanac " , derived from the name of the town in which he grew up . Macedonia and the Balkan Wars . In 1895 , war broke out in Macedonia against the Ottoman Empire . Pećanac took part in the Chetnik action against the Ottoman army and fought in numerous areas including Šuplja Stena ( near Pčinja ) and the village of Čelopek . The deacon of the Vladika of Žiča and commander ( ) Jovan Grković - Gapon suggested awarding Pećanac the title of " vojvoda " . At a Christmas - day meeting in 1904 , Pećanac received the title at the age of 25 . In the period between 1905 and 1907 , he led several major battles against the Ottoman army in the Skopje region . In 1908 , Pećanac married Sofia Milosavljević from the town of Aleksinac . He went on to father four children with her . In 1910 , as the struggles in Macedonia intensified , he left his children and pregnant wife , and returned to the battlefield . In the First Balkan War , fought from October 1912 to May 1913 , Pećanac was mobilised in the Serbian Third Army , holding the rank of sergeant in the Morava Division . He took part in the defeat of the Albanians in Merdare , the Battle of Kumanovo and the liberation of Metohija . During the Second Balkan War , fought from 29 June to 10 August 1913 , Pećanac is believed to have been stationed at the front at Kitka on Osogovo Mountain along the Zletovska and Bregalnica rivers . There , his division took part in the Battle of Bregalnica with the Bulgarians . After the Bulgarian attacks failed , they sent parliamentarians to seek a truce , but the Serbian side refused and the fighting continued . After his division had endured six days of heavy fighting , the Bulgarians were defeated at Grljani near Vinica . World War I . Following the disastrous end to the Serbian campaign in late 1915 , Pećanac escaped to Corfu along with the retreating Serbian army and government , and ultimately joined the Salonika front . In 1915 , Pećanac had received various medals for his " merit in fighting " including three gold medals for bravery , one for military virtue , and the Order of the Star of Karađorđe ( 4th Class ) for his service in World War I and possibly also for his prior military feats . In September 1916 , the Serbian high command sent then Lieutenant Pećanac by air to Mehane ( south - west of Niš in the Toplica region ) to prepare a guerrilla uprising in support of a planned Allied offensive . There , Pećanac contacted several groups of guerrillas , known as " comitadji " . Pećanac joined forces with local leader Kosta Vojinović and they both established headquarters on Mount Kopaonik . Rivalry quickly developed between the two leaders , mainly because Pećanac only had orders to prepare to support the planned Allied offensive , but Vojinović was conducting operations that might result in pre - emptive action by the Bulgarian occupation forces . Matters came to a head in January – February 1917 when the Bulgarians began conscripting local Serbs for military service . At a meeting of guerrilla leaders to discuss whether they should commence a general uprising , Pećanac was outvoted . However , events had overtaken the leaders , and they were essentially joining a popular uprising that was already underway . After guerrillas under Pećanac ' s command engaged the Bulgarians he was hailed as a leader of the resistance , although he had serious reservations about the eventual outcome once the Bulgarians and Austro - Hungarians committed large numbers of troops to subdue the uprising . The guerrillas were closing on Niš in early March when the occupying forces went on the offensive . Pećanac advised his fighters to hide out in the woods and mountains , while Vojinović ordered his to fight to the death . By 25 March , the uprising had been crushed . In April 1917 , Pećanac re - emerged with his guerrillas , attacking a railway station , destroying a bridge and raiding a Bulgarian village on the border . Pećanac avoided a further offensive by the occupation forces in July by disappearing into the mountains once again . After emerging for a short time , in September – October 1917 Pećanac again dispersed his guerrillas and infiltrated the Austro - Hungarian occupied zone where he remained in hiding until mid - 1918 . Between the two World Wars he was the most prominent figure in the Chetnik movement , and also had a leading role in the Association against Bulgarian Bandits , a notorious organisation that arbitrarily terrorised Bulgarians in the Štip region . In 1932 , he became the president of the Chetnik Association . By opening membership of the Chetnik Association to new younger members that had not served in World War I , he grew the organisation during the 1930s from a nationalist veterans ' association focused on protecting veterans ' rights to an aggressively partisan Serb political organisation with 500 , 000 members throughout the Kingdom of Yugoslavia . During this period , Pećanac formed close ties with the far - right Yugoslav Radical Union government of Milan Stojadinović , and was known for his hostility to the Yugoslav Communist Party , which made him popular with conservatives such as the Yugoslav Radical Union . World War II . Shortly before the Axis invasion of the Kingdom of Yugoslavia in April 1941 , Pećanac was requested by the Yugoslav Ministry of the Army and Navy to prepare for guerrilla operations and guard the southern area of Serbia , Macedonia , and Kosovo from pro - Bulgarians and pro - Albanians in the region . He was given arms and money , and managed to arm several hundred men in the Toplica River valley in southern Serbia . Pećanac ' s force remained intact after the German occupation of Serbia and supplemented its strength from Serb refugees fleeing Macedonia and Kosovo . In the early summer of 1941 Pećanac ' s detachments fought against Albanian bands . At this time and for a considerable time after , only detachments under Pećanac were identified by the term " Chetnik " . With the formation of the communist Yugoslav Partisans , Pećanac gave up any interest in resistance and by late August came to agreements with both the Serbian puppet government and the German authorities to carry out attacks against the Partisans . On 18 August 1941 , while he was concluding arrangements with the Germans , Pećanac received a letter from Draža Mihailović requesting an agreement be reached where Pećanac would control the Chetniks south of the Western Morava River while Mihailović would control the Chetniks in all other areas . Pećanac declined his request and suggested that he might offer Mihailović the chief of staff position and recommended Mihailović ' s detachments disband and join his detachments . In the meantime , Pećanac had arranged for the transfer of several thousand of his Chetniks to the Serbian Gendarmerie to act as German auxiliaries . On 27 August , Pećanac issued an open " Proclamation to the Dear People " , in which he portrayed himself as the defender and protector of Serbs and called " on detachments that have been formed without his approval " to come together under his command . He demanded that individuals hiding in the forests return to their homes immediately and that acts of sabotage on occupation authorities cease or suffer the punishment of death . In September 1941 , some of Pećanac ' s subordinates broke ranks to join with the Partisans in fighting the Germans and their Serbian auxiliaries . In the Kopoanik region , a previously loyal subordinate of Pećanac began attacking local gendarmerie stations and clashing with armed bands of Albanian Muslims . By the end of October the Germans decided to stop arming the " unreliable " elements within Pećanac ' s Chetniks , and attached the remainder to their other Serbian auxiliary forces . On 7 October 1941 , Pećanac sent a request to the head of the Serbian puppet government , Milan Nedić for stronger organization , supplies , arms , salary funds , and more . Over time his requests were fulfilled and a German liaison officer was appointed at Pećanac ' s headquarters to help coordinate actions . On 17 January 1942 , according to German data , 72 Chetnik officers and 7 , 963 men were being provided for by the Serbian Gendarmerie Command . This fell short of the maximum authorized size of 8 , 745 men and included two or three thousand of Mihailović ' s Chetniks who were legalized in November 1941 . In the same month , Pećanac sought permission from the Italians for his forces to move into eastern Montenegro , but was refused over Italian concerns that the Chetniks would move into the Sandžak . In April 1942 , the German Commanding General in Serbia , " General der Artillerie " ( General ) Paul Bader , issued orders giving unit numbers C39 to C101 to the Pećanac Chetnik detachments , which were put under the command of the local German division or area command post . These orders also required the deployment of a German liaison officer with all detachments engaged in operations , and limited their movement outside their assigned area . Supply of arms and ammunition was also controlled . In July 1942 , Mihailović arranged for the Yugoslav government - in - exile to denounce Pećanac as a traitor , and his continuing collaboration ruined what remained of the reputation he had developed in the Balkan Wars and World War I . The Germans soon found that Pećanac ' s units were inefficient , unreliable , and of little military aid to them . Pećanac ' s Chetniks regularly clashed and had rivalries with other German auxiliaries such as the Serbian State Guard and Serbian Volunteer Command and also with Mihailović ' s Chetniks . The Germans and the puppet government commenced disbanding them in September 1942 , and all but one was dissolved by the end of 1942 . The last detachment was dissolved in March 1943 . His followers were dispersed to other German auxiliary forces , German labour units , and prisoner - of - war camps . Many deserted to join Mihailović . Nothing is known of Pećanac ' s activities in the months that followed except that he was interned for some time by the Serbian puppet government . Death . Accounts of Pećanac ' s capture and death vary . According to one account , Pećanac , four of his leaders and 40 of their followers were captured by forces loyal to Mihailović in February 1944 . All were killed within days except Pećanac , who remained in custody to write his war memoirs before being executed on 5 May 1944 . Another source states he was assassinated on 6 June 1944 by Chetniks loyal to Mihailović .
