after the rebellion. The uprising erupted on 21 February. 300 Chetniks gathered in the village of
Obilić near Leskovac. Those under the leadership of
Kosta Vojinović voted in support of an uprising and outvoted
Kosta Pećanac by thirteen against two. Pećanac had to support the uprising and lead it in order to retain his reputation. However, they found themselves in the middle of the uprising. Per Bulgarian estimates, there were 5,750–7,800 insurgents, while historians have estimated 300–500 and 4,000. According to historian
Marko Attila Hoare, the uprising had 15,000 participants in total, with at least 4,000 armed rebels. The rebellion included the areas of Toplica, Jablanica, Jastrebac, and eastern and central parts of
Kopaonik. The rebels liberated Kuršumlija (27 February), Lebane (1 March), Prokuplje (3 March) and Blace (5 March). Having broken out in the Toplica region, the rebellion expanded into territories on the right bank of the
West Morava (Vlasotince, Crna Trava, Vranje area), and in the West Morava valley, including the
Sokobanja and
Svrljig areas. The rebels established civilian organs of government in the liberated areas such as municipalities, courts, hospitals and post offices, but without central authority. In early March, Colonel
Aleksandar Protogerov became the chief of the Morava Area. By 7 March, Bulgarian troops had concentrated around 15 battalions with 22 machine guns and 28 cannons. In their attack on 8 March, Bulgarians used around 5 battalions, with strong artillery and air support, while Albanian detachments also took part. The Austro-Hungarian supreme command allocated two battalions of the 102nd Infantry Regiment together with a hill battery from the Socha front, the 3rd border battalion and a gendarmerie battalion from
Bosnia. Around 30,000 men of the occupiers' armies have been estimated, of whom 25,000 to 26,000 were involved in operations. On 10 March, Protogerov issued an ultimatum to the rebels to surrender within five days, or otherwise they would be executed, their homes burnt down and their families deported. None of the rebels surrendered.
Internal Macedonian-Adrianople Revolutionary Organization (IMARO) detachments led by
Tane Nikolov participated in the fight against the rebels. The Austro-Hungarian attack started on 12 March from the Dubci-Zlatari sector. Per military reports on 14 March, an Austro-Hungarian detachment of around 630 men, which had been reinforced with 2 cannons and around 170 men, ended up having 2 officers and 50 soldiers killed, 16 wounded, 126 missing and 22 ill soldiers. Their supply train consisting of 20 men, 1 doctor and 20 horses was captured by rebels. On 18 March, the German consul reported that one Austro-Hungarian officer and 53 soldiers were killed, while 120 went missing. After several days of fighting, the Bulgarians entered
Prokuplje on 14 March, and the Austro-Hungarians entered
Kuršumlija on 16 March. On 25 March, the order there was fully restored. IMARO commander and Bulgarian officer
Todor Aleksandrov participated in the uprising's violent suppression. Around 20,000 civilians were killed as a result of the uprising. The Bulgarian troops burned and destroyed the village of Gajtan, massacring 200 people, mostly women and children. In the village of Barje, they burned 42 people to death in a house, including a woman and 10 children.
Mass rape also took place. More than 80,000 people were deported. IMARO detachments also committed atrocities such as killing, pillaging and raping. The
Military General Governorate of Serbia executed around 600 rebels and civilians suspected of giving the rebels support. Rebels also targeted
Serbs who had worked for the occupiers and had material benefits. == Aftermath and legacy ==
