The First Serbian Uprising against Ottoman rule erupted in February 1804, with Karađorđe as its leader.[1] On 19 May 1809, 3,000 Serbian rebels under the command of Stevan Sinđelić were attacked by the Ottomans on Čegar Hill, in Niš. The rebels were plagued by lack of coordination, largely due to the rivalry between commanders Miloje Petrović and Petar Dobrnjac.
