Fragment of the combat report of Lieutenant Mieczysław Michalski, the commander of the 2nd battalion of the 32nd Regiment, to the regiment commander about the murder of the Greek Catholic priest Wołodymyr Kostyszyn at the presbytery in Wola Niżna:
„The operational group under the command of Lieutenant Michalski set off on April 20, 1946 from the village of Rymanów Zdrój. at 10.00 p.m. consisting of 5 officers, 58 privates and 2 private radio operators with one car plus 4 wagons and it reached the village of Jaśliska at midnight on the same day, that is on April 20, 1946. At 00:30, the operational group set off towards the village of Wisłok Large. In the village of Wola Niżna at 01.35 a cart with Christmas provisions for Banderites (eggs, rolls, sausage and cakes) was stopped, approximately provisions for 100 people. In the village of Wola Niżna, during the search of a priest, one woman and one coachman who was carrying food for the Bandera followers were intercepted. The priest of the parish of the village of Wola Niżna explained that there were no Bandera followers in his house, and if they were, he did not know about it. During the search of the house, one woman was found (hidden in bed in one of the priest's rooms, fully dressed and belonging to the 'Bohun' group). This woman was collecting food products for the Bandera followers in the village of Wola Niżna. During the interrogation of the priest, the light in the apartment went out. At that moment, the priest attacked Lieutenant Michalski, trying to take the machine gun from him. At the same time, the commander of the 6th Rifle Company, Second Lieutenant Biskupski, used a weapon in defense of the battalion commander, fatally wounding the priest, who died after a short time. The death was confirmed on the spot by Lieutenant Lebedev, the commander of the medical platoon of the 2nd battalion”.
