There were several attempts to recapture Knin in the first years following its fall. In September 1522, Karlović gathered an army and attacked Ottoman forces in the vicinity of Knin, capturing several Ottoman soldiers, including the goldsmith of Husrev Bey. Aid was expected from Austrian Archduke Ferdinand, who pledged to help regain the lost forts and strengthen the ones still under Croatian control. In June, Ferdinand sent four hundred troops to Karlović, led by Nicholas, Count of Salm, who met with Karlović and helped in the organisation of the defence. While those forces enabled the Croatians to hold their ground, they were too weak to capture Knin. There were two more Croatian attacks in the area of Knin in 1529 and 1530. The first ended with the capture of 24 Ottoman soldiers, while in the second one in July 1530, around 100 cavalrymen from Bihać reached the area of Knin and the Cetina River, where local Christian troops had been gathered by harambaša Nikola Bidojević. The details of this attack are not known.
