[1] A royal army numbering about 4,000 soldiers under the Slavonian ban Nikola Banffy eventually invaded her territories and besieged Knin during September and October 1344.
Protected by significant fortifications, the ban was unable to storm the city, and instead pillaged the surrounding villages before mounting the hill Spas in a final attempt.
As a result of this, another siege was laid to Knin by Nikola in 1345 together with the Ban of Bosnia Stjepan I Kotromanić as the main royal army under Louis I slowly approached consisting of tens of thousands of soldiers in total.
Both of these acts finally pressured Vladislava to sign a contract with the two bans in July 1345, during which she ceded the castles of Knin, Ostrog [hr], Počitelj, Srb, and Unac to the king.
In spite of this resolution, Vladislava was not happy, and spent the rest of her years in a voluntary exile in Split (since 1346), which was then under the control of the Republic of Venice.
