In the Battle of Mišar, Mehmed-"bey" Kulenović commanded the left wing of the Bosnian Ottoman army, that is cavalry of Bosnian spahis. According to the recorded statements of the participants and the analysis of some Serbian military historians, during the Battle of Mišar, the Serbian insurgents mostly limited themselves to fighting from a fortified trench and rarely dared to sally forth. The Serbian cavalry, which was intended as a reserve and located not far from the trench near the village of Žabar, was quickly defeated by the well-trained and experienced cavalry of the Bosnian spahis, led by Mehmed-"bey" Kulenović, during the first serious use on Mišar. The fighting lasted for several days with mutual losses. The success of the Serb insurgents consisted in holding on, thus preventing the Bosnian Ottoman army from passing towards besieged Belgrade. On August 13, 1806, leading a renewed cavalry charge on the trench, Mehmed-"bey" Kulenović was challenged to a duel by Duke Luka Lazarević. Mehmed-"bey" came out of the duel as the winner, but then he was killed from a pre-set ambush by Serbian insurgents who accompanied Duke Luka Lazarevic. The body of Mehmed-"bey" Kulenović was transferred to Bosnia and buried in the courtyard of the mosque in Janja, where his turbe is still located. Filip Višnjić sang about Mehmed-"bey" Kulenović in the songs "Knez Ivan Knežević" and "Boj na Mišaru", taking him as a central figure and the commander-in-chief of the Bosnian eyalet army. Mehmed-"bey" Kulenović was succeeded as captain of the Stara Ostrovica capitancy by his son Ahmed-"bey" Kulenović (Kulinović).
