The Croatian army, led by Ban Ladislav of Egervár and Knez (Prince) Bernardin Frankopan, defeated the Ottomans who were on their way back from a raid into Carniola, to the Sanjak of Bosnia, carrying booty and Christian captives to be sold into slavery.

[4] With the death of King Matthias Corvinus in 1490 the 7-year truce with Sultan Bayezid II ended and the Ottomans renewed their raids into Croatia and southwestern Hungary.

[5] One such raid started in 1491 when Mihaloğlu Hasan Bey from the Sanjak of Bosnia crossed the Una River and led an army consisting of around 10,000 light cavalrymen, known as the Akıncı, across Croatia into lower Carniola.

[9] The Ottoman army was returning towards the Sanjak of Bosnia on their traditional route, Vrhovine – Homoljac – Korenica – Vrpile – Krbava field, taking with them a huge number of prisoners.

At the same time, Bernardin Frankopan who earlier fought a battle against them on Kupa source, organized a pursuit so the Ottomans reached Vrpile exhausted.
