Fought on the Čegar hill situated between the villages of Donji Matejevac and Kamenica near Niš in what is today southeastern Serbia, it ended in an Ottoman victory.

Commander Stevan Sinđelić famously blew up the gunpowder magazine when the Ottomans overtook his trench, killing everyone in it.

On April 15, 1809, the 10,000 Serbian rebels approached the villages of Kamenica, Donji and Gornji Matejevac, near the Fortress of Niš with Miloje Petrović as Commander-in-chief.

The fifth trench was in the mountain above Kamenica and under the control of vojvoda Paulj Matejić while the sixth one was in Donji Matejevac.

The Serbs then launched several attacks against the Niš Fortress, but they could not take the fort due to lack of heavy artillery.

But Hurshid had different tactics; after every Serbian attack, he was offered negotiations and this way he bought time while fresh troops arrived.

"It was earlier believed that the Serbian defeat at Kamenica was due to Miloje Trnavac, a commander of the Niš front.
