According to the 1931 CSO census, the village of Łozowa had 160 homesteads and 769 inhabitants. Poles predominated - 90% of the population, 5 Ukrainian families and 10 mixed families lived here.

The attack on the Poles by the Ukrainians took place on the night of 28/29 December 1944. A resident of the village, Karol Mazurkiewicz, managed to ring the church bell, thanks to which many people managed to hide. The Łozowa massacre lasted 2 hours. It was interrupted by the arrival of a Soviet armoured train, which fired several shots as a scare.

The victims of the massacre were buried on 1.01.1945 in a common grave near the church. During the burial, the Bandera fired on the funeral procession, killing 5 more people. These victims were buried in one grave together with the victims of 28/29 December 1944. A local Ukrainian, Ivan Snihur, erected a cross on the grave. It did not stand for long - it was destroyed by unknown perpetrators. After the displacement of the Poles, the local bandits devastated the grave and turned the area into a cattle pasture. During the period of "perestroika" in the 1980s, when a school was built on the site of the destroyed church, this grave was exhumed and the remains of the victims were moved to the Greek Catholic cemetery in the neighbouring village of Szlachcińce, where a stone monument with an inscription in Ukrainian was erected on the grave: "To the Łozowiczans who died at the hands of bourgeois Ukrainian nationalists" [translation]. In 1991, the inscription on the monument was scratched out and the monument itself was smashed. The following year, the tombstone was restored, but the content of the inscription was changed.

In 2007. The Council for the Protection of the Memory of Struggle and Martyrdom led to the renovation and redesign of the memorial on the victims' grave. It was consecrated on 5.07.2008 during a solemn mass for the intention of the victims from Ihrowica, Berezovica Mala, Plotycza and Lozowa (buried in Szlachcińce). The commemoration was erected in the form of a cross and plaques with the names of the victims next to it. The whole was made of light-coloured granite. The inscription reads: "With the smoke of fires, with the dust of brotherly blood / to you, Lord, cries this voice! / Kornel Ujejski // To the memory / of the resting here / about 120 Poles / inhabitants of the village / of Łozów / murdered / on 29 December 1944 / may they rest in peace / Government of the Republic of Poland / Families / 2007".
