Karađorđe lent Kara-Marko an army and vojvoda (general) Lazar Mutap to liberate Osat and Srebrenica from the Ottomans.
With Hadži-Melentije, Milan Obrenović, Mateja Nenadović and Sima Birčanin he led the Serb rebel army against the Turks on Lučindan 1808 in Oklenac, Vranjkovina in Osat, and Pribićevac near Srebrenica.
Luka Lazarević mentioned him in his memoirs, regarding fights in Osat and Srebrenica in 1809: "Karamarko expels the Turks, and rises the [Orthodox] Christians against them".
[1] After Hadži-Melentije left for the Russian Empire in 1810, Karađorđe appointed Kara-Marko the vojvoda of the Sokol nahija (district) and a military senior (starešina) in Rača.
Due to his loyalty to Karađorđe, the new Serbian leader Miloš Obrenović ordered his murder and had his severed head given to the Vizier of Belgrade.
