Jajce had been conquered by the Hungarians in December 1463, after a siege that followed Matthias Corvinus' offensive into Bosnia in late September 1463.[2] It is said that Corvinus managed to take over sixty places in Bosnia, many of which were fortified.[2] In July and August 1464, Sultan Mehmed II personally commanded the siege to take back Jajce.[2] The Ottoman army had probably set out from Edirne in late May according to C. Imber, 'since Malipiero dates the siege of Jajce to between 10 July and 24 August, and Enveri [...] also says that it began in July'.[3]
