and Gvozdansko, set by Zrinski family (last landlord family). They were often left unpaid and in poor conditions, further complicating defence. Thus Pounje (area around river Una) eventually became abandoned. We can expect that a similar fate happened to Žirovac but there are no records. Finally, the entire area came under Turkish rule and was under it for about 160 years. Military Frontier During the period of Military Frontier, mass migrations of the population went on all the time in both directions and in several waves. First fleeing away from Turks, then those who collaborated with the Turks were fleeing after their fall, and in the second direction people fleeing from the vengeance of those arriving. Most were from Potkozarsko area and from the Sana'a basin. In order to keep the residents, the Austro-Hungarian government awarded all to be free, with no obligation to any landlord, but under conditions that were not much easier: they were obligated to be prepared for military campaigns at any time, to work to restore roads and maintain Fortifications. Often these commitments were too hard and sparked occasional rebellions. Gornji Žirovac was just at the "dry border", and during this time, its frontiersmen had built a series of roads and "straža" (guard stations), which were part of the Austro-Hungarian defensive line, known as "cordon". From a series of guard stations along the border, in the vicinity of Gornji Žirovac there were seven of them. In later years frequency of stations was reduced and only two or three remained, with one newly built – CP Radašnica, which was marked as "Kastell", that is – of something greater importance. The existence of a larger fortress was not recorded, mostly because the later peace treaties with the Turks forbid new fortifications of any larger scale in this area. The place has seen a lot of military activity, some of which was described in military reports of Austro-Hungarian military. One such description from 1789 tells about a group of 31 men surrounded in one Chardak by the Turks. When surrender was refused, the Turks tried to burn Chardak with a wagon filled with straw, pushed by eight men. Chardak snipers however managed to shoot down all eight of them. Turks then tried to let wagon roll downhill, but the burning wagon got stuck in bushes and they gave up, but did took time to burn and pillage village. It
