 As it happened, Hungarians were heavily defeated in this battle, with most of the present Hungarian high nobility captured and ransomed later on, and they were not to undertake any major offensive against the Ottomans or Bosnian kingdom until the Second Battle of Kosovo in 1448.Turks had conquered the city of Doboj and its fortress in 1476 and in following decades had the fortress completely reconstructed and gave it a new shape by adding the second outer wall and additional structures.Particularly large works were done in the early summer of 1490 where some 1,500 men were employed under master-builder Ibrahim.
