 The plan was accepted on 24 June and the construction at Węgierska Górka and Korbielów started almost immediately, in early July.The bunkers around Węgierska Górka were to form a crescent-shaped defensive position guarding the village and the town in the valley between the hills of over 1000 metres of altitude.All works were carried out by a mobilized unit of Work Battalions led by Major Śliwiński, with civilians forbidden to enter the construction area.
