capture its fortress. From there he turned northwest and entered Carniola and Styria, plundering the countryside. The same year, a war broke out between the newly appointed ban of Croatia, Emerik Derenčin (), and the Frankopans, allied with Karlo Kurjaković (of the Gusić's), for control over Senj and several other towns. By mid-July 1493, counts Bernardin Frankopan and Ivan VIII (Anž) Frankopan, had the upper hand in the war and were besieging Senj. The siege was lifted after an army led by ban Derenčin was sent to help Senj, and the Frankopan army retreated to Sokolac. In the meantime, the Frankopans were accused of cooperating with the Ottomans, although their estates were also being ravaged. News of the incoming Ottoman army forced them to make peace. On their way back, the Ottomans sacked Modruš, in northern Lika, then owned by the Frankopan noble family. The Frankopans and ban Derenčin wanted to intercept the Ottomans, and gathered an army of around 3,000 cavalry and 8,000 infantry from all parts of Croatia, however a part of the army consisted of peasants from the surrounding areas of Krbava. Ivan Frankopan Cetinski, one of distinguished Croatian nobles advocated ambushing the Ottoman army in nearby ravines and canyons. Ban Derenčin, however, as supreme commander, dismissed such idea, accusing Croats of cowardice and opted for a battle on the open field. Cetinski, as written by Tomašić, replied by telling: "This isn't like riding from one town to another in Hungary. Today, you shall see how Turks fight their battles" and accused him back of causing the dissolution of Croatian Kingdom. Ultimately, Derenčin's opinion prevailed and Croatian commanders agreed to face the Ottoman army in an open battle at the Krbava field, near the town of Udbina in central Croatia, although Ivan Frankopan Cetinski argued that an ambush in the canyons and ravines would be a better option. Battle The Ottomans entered the Krbava field through the lowest and narrowest local mountain pass of Gorica, unlike two years earlier through the Vrpile pass where they suffered a huge defeat. Before the battle, Hadım Yakup Pasha ordered the execution of Christian captives near Jelšani (present-day Jošan) so that they could not help the Croatians in the midst of battle. Turkish historian H. E. Efendi, also notes that he held "a heated speech" to his men in order to "invoke their wrath against the enemies of The Only God".
