The Banderites and local The Ukrainians and villages from nearby burnt the village and the parish church, and murdered 145 Poles, 25 were wounded and burned. „According to the report of our Delegation in Bóbrka on May 22 this year. at. At 5 a.m., a strong Ukrainian gang, partly in German uniforms and helmets, well–armed, attacked the Polish population of the hamlet of Brzezina, belonging to the Bryńce Zagórne group, the commune of Wybranówka [Lwów] and, according to the stories of the Poles who had escaped from there, murdered about 120 men there., women and children, and burned down the entire hamlet together with the Polish church. The size and number of victims could not be determined in detail by the Delegation, because no one had the courage to go to this town lying among the forests after the attack”.

The attack on the village took place around 5 am. The first victim was a boy driving horses to pasture. Then the attackers ran across the unprotected village, murdering the Polish population regardless of sex and age, and robbing and setting fire to houses. This village is also described as Brzezina. „after the attacks of Ukrainian bands on Huta Szczerzecka and Chocimsko, the Polish inhabitants of Brzeziny, feeling that they would face a similar fate, did not stay at their homes at night. They had prepared shelters in the surrounding forests. When it was dark, and let's remember that it was late spring, the residents left their homes and returned to them in the early morning. Of course, all the more valuable things were already buried in the ground. Until the last day, the Church performed her service to the faithful. On Sunday, May 21, Father Liwicki, after celebrating two masses, he closed the church and took the shortcut path to Wybranówka, from where went to Lviv in the «passenger car». Monday morning on May 22 greeted the residents with a wonderful sun. who could have guessed that this day would be the day of the end of Polish existence in Brzeziny, the Parish of St. Stanisław Biskupa and Martyr, as well as the church, not to mention the rectory and organist. In the early morning, a girl named Petruś Maria (from a Ukrainian–Polish family) from Kopanina, who is carrying milk in a kite to the catchment, that had to be put aside during the German occupation, shouts to everyone that they are already murdering in Kopanin. Before they broke up and began to flee towards the forest and the hiding places existing there, the UPA bands had already surrounded Brzeziny around. People started to run too late to make it before the lap closed. Quite a few have managed to get the cornfields and hide in them. But it was an illusory protection, because the Ukrainians, realizing the situation, after some time began to comb the fields, looking for those who were hiding. The murder was total. this time, all Poles were murdered, unlike in Huta Szczerzecka or Hucisko, where women and children were left alive”.

The next day I found out that my father, Michał, was shot by the mill stream where he had been lying for two days, and then stripped of his sheepskin coat and shoes, the Ukrainians buried him on the shore. In general, the Ukrainians, fearing the plague, after two days buried all the murdered in the places where they were killed. Thus, many bodies fertilized the soil there, and their bones are still there, scattered on the soil of Brzeziny. And these bodies were added to a total of 145!  […] And so nobody disturbed the murders, burning and destruction, and the action ended at dusk. But none of the Poles in hiding had dared yet that night, when the glow of the burning Birkenau was visible, hen, hen, back. Anyway, there was really nothing to do. Out of the existing 56 houses in Brzezina, only four have survived to this day, inhabited by Ukrainian families. The church was burnt, the tower does not exist, there is no trace of the rectory building or the building of the so–called organists.

Ks. Franciszek Wołyniak quotes a poem by a woman from the village of Bryńce Zagórne, written in May 1944:
 […] The thirteenth mother ran with the children
to a Ukrainian woman and asks you to hide me,
because I have little children.
She refused to save her.
They took her and murdered her with the children.
Hands nailed to the threshold,
They cut their bodies with a saw and set the house on fire.
They spent the whole family in the fourteenth house.
Tongues were cut out, entrails were released
And if they wanted to, they murdered it.
 […] Oh God! You our good God!
There were 50 farms in our village
And the church with the image of the Mother of God.
Today there is nothing left. Everything is burnt.
We die your death, Jazu, the death of the cross
We Poles, always faithful to you
We're running away today!.
