The siege was planned as a diversionary attack[2] from main Habsburg offensive on Danube river, and was called off after several failed storming attempts.

In the first half of 16th century, the town of Bihać was an important Croatian strongpoint in its defensive efforts to counter Ottoman expansion.

Parallel with main Habsburg efforts against Ottoman Hungary, ban of Croatia and Karlovac Generalcy began their own successful anti-Ottoman campaigns in Slavonia, Pounje and Lika.

[4] Besieging commanders intentionally attempted to spread false information about Bosnian pasha's relief army sent to Bihać's aid being destroyed.

[4] Croatian ban dispatched his troops on right bank of Una river towards mount Grmeč, in order to secure the background from the arrival of petential relief army.

[4] On 24 June the Habsburg commanders estimated that artillery bombardment did enough damage to the town's fortifications so they ordered to charge the city from all sides.

[5] Rumours also started to circulate that Bosnian pasha is preparing a 6000 strong relief force, with more Ottoman reinforcements arriving from Belgrade.

Historian Vjekoslav Klaić points out that when one year later emperor Leopold decided to conclude Peace treaty of Karlowitz, "The Croats lost all hope of liberating Bihać [...] which was considered the capital of Old Croatia in the aftermath of fall of Knin" in 1522.
