The testimony of Józef Waszczur, b. in 1929 in Bereżnica Wyżna:
„The Polish Army [2 October 1945 — BH] entered the village from the lower end — from the San. The commandant stopped near the former inn, and the soldiers started to burn the houses from the top end. On the way, they killed those who did not run away or hid. The army killed 13 people (they did not manage to escape because they were taking the necessary things from their homes; Poles, on the other hand, did not run away, believing that they would not be killed): Wasyl Wijtiv, his wife Maria with children Anna and Katarzyna, wife Anastazja (both old men), Katarzyna Łazoryk, Józef Wojtanowski (Pole), Maria Hnap (Polish woman), Dymitr Waszczur, Maria Chochła.
Wasyl Wijtiw with family (Maria, children: Anna, Katarzyna, Józef, Julia, Olga) hid in the basement near the house. When the military saw them, they were driven out of the basement. Mother and daughters Anna and Katarzyna were shot in the yard. The father and the children were rushed to the lower end, near the inn. They rushed on, the footbridge, did not let pass through it, and ordered to go through the water. Then they continued on the road and told them to come back. They shot them in the river: Vasyl fatally, severely wounded in the leg and Józef was left in the arm, Julia in the arm, Olga was not hit. Julia, Olga and Józef were looked after by Uncle Jerzy, he took them to Anton Wijtiv on Rapiszka .
The children — Anna, Michał and Ivan Waszczur — were sent with uncle Leszek and a cow, maybe a calf, and sheep to the forest. Meanwhile, Dmitri and Martha were dragging grain, table, cart, and tools away from the house so that they would not burn. After they were behind the cemetery, Dimitri remembered that there was a saw left in the chamber. He came back, but a soldier was already standing by the house and shots rang out. Dmitri Vashchur was shot in the back of the head, the bullet passed over his forehead so that the brain came out.
Ivan Zawiyi was also shot near his house”.

Excerpt from the memoirs of Jarosław Wijtiv (born in 1925 in Myczków) about the Ukrainians murdered in Bereznica Niżna:
„The civilians suffered the most. There were victims in Baligród, Bereżnica Niżna, and Solinka. In the village of Bereżnica Niżna in 1945 10 people were killed by bullets from the Polish Army and MO from Lesko. The army came from the side of Myczkowce. They were killed, among others Julka Wijtiwa, Hania Wijtiw, their uncle Dymitr Waszczur [in org. Wacura — BH], the Zawijski family [in org. Zawośkich — BH] (grandfather, grandmother and their two granddaughters). Most of the murdered were called Wijtiw and lived in the upper part of the village. Later, nothing was left of Bereżnica Niżna, because the Poles burned it down”.
