minnetoğlu participated in the bosnian campaign led by sultan mehmed in 1463–64 (1460–61 according to chronicler tursun beg). according to some bosnian sources he was at that time the governor of the sanjak of smederevo, or "lord of the serbian land", however, other sources treat general ali bey mihaloğlu as the "sanjak-bey" of smederevo, appointed in 1462–63. when the sultan left the siege of jajce to march against retreating hungarians, minnetoğlu was placed in charge of the siege. after the second siege in 1463 or 1464, the sultan appointed minnetoğlu as the first "sanjak-bey" (provincial governor) of the sanjak of bosnia, at first seated at jajce (later sarajevo). minnetoğlu sent 500 cavalry to the ottoman camp at zvornik, fighting the besieging hungarians. isa-beg ishaković succeeded him as bosnian governor.
