 Many of the Orthodox bishops appealed to the Archduchy of Austria for help in liberating their lands.The Uskoks, irregular soldiers in Habsburg Croatia, supported Austria, being scattered over the whole area between Senj and Ragusa (modern day Dubrovnik).With a daring raid on April 8, 1596, the Uskoks even managed to occupy the Klis Fortress, though they were unable to hold it.
