Relief of Jajce (1518)
The Battle of Jajce took place in January 1518 during a series of wars between the Ottoman forces of Husrev Beg, Beylerbey of the Bosnia Eyalet, and the Hungarian and Croatian forces led by Croatian Ban Petar Berislavić. The battle was a part of the Croatian–Ottoman wars and Ottoman–Hungarian wars. After Berislavić's tactical breakthrough to besiege adjacent Ottoman forts, Jajce remained in Christian hands.
Prelude
The fortress of Jajce was built by Hrvoje Vukčić between 1391 and 1404. The fortifications grew over the years, encompassing a citadel and later a Jajce podgrađe itself became surrounded by the wall with towers, a two gatehouse, and a bastion. After a Hrvoje's death, Jajce and its župa came to Bosnian kings' control as royal demesne, and the walled city of Jajce later became official seat of the Bosnian kingdom. The fort fell to the Ottomans in 1463 during their conquest of Kingdom of Bosnia, but was soon retaken by Hungarian king Matija Korvin's counter offensive on 26 December of the same year. Hungarians heavily fortified Jajce and adjacent castles and made the town a seat of Banate of Jajce, a cordon sanitaire whose purpose was to protect territories of Croatia and Slavonia from Ottoman akinji plundering raids.Jajce successfully withstood Ottoman attacks in 1464, 1491, 1493, 1501, 1502, 1514, and 1515. Instead of charging onto the fortress, the Ottomans eventually decided to starve it into surrender, by cutting of its food supply, preventing local people from growing food of their own food, capturing surrounding towns and keeping the town's surrounding under constant pressure by having a permanent military presence in the area. The town therefore remained a salient in Ottoman territory and as the Ottoman grip around it grew stronger, Croatian-Hungarian armies had to make forced breakthroughs into the city in order to reprovision it and keep its garrison functioning.
