After the Austrian declaration of war on the Ottomans on February 9, 1788, the Imperials expected great success on the Bosnian front, during which hostilities began.

On April 22, the Imperials began bombarding the fort using mortar batteries, and they made a breach in the walls.

[11] Major general Count Anton of the Khuen von Belasi family died of his wounds soon after the battle.

[13] After a report of the approach of a 10,000-strong Ottoman army was received, on April 26, Prince Liechtenstein abandoned the siege and retreated behind the Una River again.

Prince Liechtenstein was removed from his post in August and gave it to Ernst Gideon von Laudon.
