Ottoman force
Murad II and Ali Beg Evrenosoglu commanded the Ottoman Army. They built a wall around the city and used it to hurl stones. According to Konstantin Mihailović, the title of bey and corresponding estate was promised to the Ottoman soldier who would wave Ottoman flag on the Belgrade walls. Although Evrenosoglu already had the title of bey at that time he decided to personally lead the assault to the walls of the Belgrade castle hoping to increase his already great reputation.
