Siege of Jajce

After the fall of Travnik and royal fortress of Bobovac, in the initial days of invasion, Ottomans, led by Sultan captured the town.

This situation and Jajce under Hungarian garrison will last until 1527 when the Ottomans finally took the town, and breaking the lines advanced northward to Hungary and westward to Bihać,[7][8][9] which was part of the Kingdom of Croatia.

Beginning from the diet of Buda of 1462 some Bosnian-Hungarian borderline fortresses were already guarded by the Kingdom of Hungary and King Stephen Tomašević of Bosnia was accepted as a vassal to her.

He suddenly made a flanking move to the heart of Hungary until he reached Temesvár, where he ran into John Pongrácz Voivode of Transylvania and was defeated in a fierce battle.

Stephen Tomašević was advised to entrench himself in the high mountains, although he chose to withdraw to Jajce and later to Ključ and burnt the bridges of the roads along.

[14] Turahanoğlu Ömer Bey pursued his trail taking Jajce without a fight and pushed to Ključ through the Sava river and the surrounding mountains despite the marshy ground and the general inaccessibility to the town.

[16] The sultan divided his expeditionary army into three, one led by him, one by Ömer Bey, and one by Mahmud Pasha, respectively, and raided the surrounding countries as well as completed the conquest of Bosnia.

[18][need quotation to verify] With the help of the Krstjani, Stjepan Vukčić Kosača was able to withstand the intrusion of Mehmet for a short time, before sending his youngest son as a hostage to Istanbul, and ceding all of his lands to the north of Blagaj Fort to the Empire.

[19] Mehmet II chose not to engage in winter operations and retreated bringing 100,000[dubious – discuss] prisoners and leaving Mimert (Minnet) Bey in charge in Bosnia.

Both of them promised financial aid, the Holy See granted a sum sufficient for the military service payment of 1,000 cavalry for a year.

He appointed John Pongrácz de Dengeleg as the supplies overseer and provost Gaspar Bak of Berend as the ammunition/siege engines operator.

The third contingent was recruited in Croatia, thus it arrived from the west in the direction of Bihać and was commanded by Martin Frankopan,[32] while the reinforcements from Hum led by Duke Stjepan and his son Vladislav Hercegović blocked Jajce from the south (Prozor, Donji Vakuf).

Upon the recent success among the Bosnian population, Corvinus anticipated local support[dubious – discuss] and thus instantly attacked the town of Jajce on 5–6 October, subduing it on the first try.

[37] Stephen Gerendi saved his life when he shot a waylaying Turk during the siege and thus was rewarded the right to bear personal coat of arms.
