The fall of Bihać caused fear in Croatia as it stood on the border for decades.[34] It was the last Croatian stronghold in the south and with its fall the defensive line moved north and extended from Ogulin, through Karlovac and along the Kupa River to Sisak.[28] During its spring-summer offensive of 1592, the Ottoman Empire seized Bihać and Ripač on the Una River, and Dreznik, Floriana and Cetingrad on the Korana River.
