Anna of Russia
Colceag and his son Mahmet-bey were taken to Saint Petersburg and stayed there as prisoners of war. They were freed by Empress Anna of Russia on 15 February 1740. After the peace treaty was signed, Colceag decided to return to Istanbul. On his way he was informed that Sultan Mahmud I had decided to decapitate him, considering the surrender of Khotyn an act of treason.
