On August 1465, Ballaban Badera, a sanjakbey of the Sanjak of Ohrid who was an Albanian-born janissary launched his fourth but largest campaign against Skanderbeg. He was defeated in both battles of Ohrid and Vajkal the year before. Ballaban had previously inflicted severe casualties to Skanderbeg's forces and soon received high favor from Mehmet II. He soon appointed Ballaban and Jakup Arnauti—both Albanian peasants by birth—to lead a joint-campaign against Skanderbeg's forces. According to some scholars, this act of inclusion by the Sultan was a promotion of a social revolution within Albania to wean forces away from Skanderbeg.
