Pańska Dolina no longer exists . The village was liquidated during the Polish population transfers after World War II , when the Kresy macroregion was formally incorporated into the Soviet Union ( as agreed at the Potsdam Conference of 1945 ) . Pańska Dolina used to be located in Gmina Młynów , Powiat Dubno ( county ) , of the Wołyń Voivodeship , before the Nazi German and Soviet invasions of Poland in September 1939 . Its former location can be found near Mlyniv in Dubno Raion of present-day Ukraine . The village was one of several points of Polish defence against the OUN-UPA murderous raids during the wave of massacres of Poles in Volhynia between 1942 and 1945 . The Polish self-defence unit represented mostly by Armia Krajowa managed to hold their position there till the arrival of the Red Army in 1944 . The village offered protection to Polish and Jewish escapees from the area , provided food and shelter , and organised counter-attacks against the UPA attackers
