In 1939 he took up the position of vicar in the Greek Catholic parish of Oleszyce, on the Tarnogrodzki Plateau, on the Przerwa River, surrounded on three sides by the Sieniawa forest complex, located in the Polish county of Lubaczów, in the northern part of the Lviv Voivodeship. The parish was based on the town of Oleszyce, which in 1939 had an estimated population of c. 3,400 people, of whom Greek Catholic Ukrainians constituted c. 21%, Roman Catholic Poles c. 26%, and Jews c. 52% of the inhabitants, and on the adjacent village of Oleszyce Stare, in which lived c. 2,900 people: c. 59% Greek Catholic Ukrainians, c. 36% Roman Catholic Poles, and c. 4% Jews. There were Greek Catholic churches in both, but resided in Oleszyce Stare.

After the German attack on Poland on 01.09.1939 — the Russians attacked 17 days later, in accordance with the genocidal agreement between the two allies, known as the Molotov–Ribbentrop Pact of 23.08.1939 — and the beginning of World War II, German troops entered Oleszyce on 12.09.1939. On 14‐16.09.1939, a battle between the Polish 21st Mountain Infantry Division and the Germans took place in the area, during which the commander of the Polish division, Joseph Rudolf Kustroń, the first Polish general to fall during the September Campaign of 1939, was killed. Four days later, on 20.09.1939, Russian troops reached Oleszyce, and in accordance with the agreement between the two allies, later confirmed by the so‐called „Treaty on the Border and Friendship between Germany and Russia” of 28.09.1939, also known as the Second Molotov–Ribbentrop Pact, they occupied the town. The Russian occupation began.

However, was not there, because moved — under unknown circumstances — to the village of Dzików Stary, c. 12 km to the northwest, which in 1939 had an estimated population of c. 2,600 people, of whom c. 52% were Greek Catholic Ukrainians, c. 33% Roman Catholics, the majority of them prob. Ukrainians, and c. 15% Jews. The Oleszyce parish town was separated by the border between the two occupiers, as Dzików Stary found itself in the Germ. Kreishauptmannschaft Biłgoraj (Eng. Biłograj County) in the Germ. Distrikt Lublin (Eng. District of Lublin), part of the German‐occupied and run quasi‐state called the Germ. Generalgouvernement (Eng. General Governorate), i.e. GG. The Germ. SS‐ und Polizeiführer (Eng. SS and Police Commander) in the Germ. Distrikt Lublin, and de facto deputy governor of this district, was one of the greatest criminals in human history, the Austrian, Odilo Lotario Globočnik, whom one historian described as „the most vile individual in the most vile organization that has ever existed”.

The Germans immediately introduced terror against the Polish population. One of its goals was to attempt to break the influence of the Roman Catholic Church and Polish culture. It was also expressed e.g. by a clear preference for the Ukrainian population, support for the Orthodoxy, Greek Catholic rite and Ukrainian–language education in schools. The policy of supporting the Ukrainian element was perhaps most visible in the social policy of the GG. Germany permitted the operation of social and charitable organizations, but only the Ukrainian Central Committee UCC was partially financed from the GG budget. Additionally, it could use funds from Ukrainian cooperatives. The Polish Central Welfare Council RGO and the Jewish Social Self‐Help JSS had to rely exclusively on voluntary contributions from donors. As a result, Polish and Jewish organizations could only conduct charitable activities: supporting food supplies, aid for refugees, etc. Ukrainians/Rusyns, using GG funds, built Ukrainian/Rusyn hospitals, orphanages, nurseries, and schools. In many places, schools were taken from Polish hands and handed over to Ukrainians. Sometimes Catholic priests were expelled from parishes and churches were converted into Orthodox churches. This led to the intensification of the Polish–Ukrainian conflict. It couldn"t have been otherwise, as on the entrance door of the waiting room of the main railway station in Kraków there was an inscription Germ. „Nur für Deutsche aus dem Reich, Volksdeutsche und Ukrainer” (Eng. „Only for Germans from the Reich, Volksdeutsche and Ukrainians”).

In 06.1940, in Dzików Stary, the Germans organized a Germ. Arbeitslager (Eng. labor camp) for c. 1,000 Jews brought from Cieszanów, which was a branch of the AL Belzec camp. The Jews slaved on the construction of the Germ. Burggraben (Eng. moat), i.e. anti‐tank ditch, fence and other fortifications on the German–Russian occupation border, which were part of the preparations for the German plan Germ. Operation Otto, later renamed Germ. Operation Barbarossa, i.e. the war plan against the Russians. The camp, managed by the Germ. Germ. Die Schutzstaffel der NSDAP (Eng. NSDAP Protection Squad), i.e. «SS», a paramilitary formation subordinate to the ruling National Socialist German Workers' Party NSDAP in Germany, was under the command of the génocidaire Globočnik. Several dozen Jews died of exhaustion and disease. In 11.1940, the camp was liquidated and the Jews from Dzików Stary were deported.

Operation Barbarossa began on 22.06.1941, when the Germans attacked their erstwhile ally, the Russians. On the same day, German troops entered Oleszyce. The German occupation began there and already in 07.1941 could return to his parish. Oleszyce became part of the Germ. Kreishauptmannschaft Rawa Ruska (Eng. Rawa Ruska County) in the Germ. Distrikt Galizien (Eng. District of Galicia) within the expanded GG.

The period 1941‐1943 was marked in particular by the extermination of Jews. From the beginning of 1942, the Germans implemented the genocidal plan Germ. «Endlösung der Judenfrage» (Eng. Final Solution of the Jewish Question), which in the GG was codenamed Germ. «Aktion Reinhardt» (Eng. Operation Reinhardt). Significant part in it took the units of the Ukrainian, collaborative Germ. Ukrainische Hilfspolizei (Eng. Ukrainian Auxiliary Police), also operating as the Germ. Schutzmannschaft (Eng. Security Battalions), i.e. Schuma. Jews from Oleszyce — in 1941 there were prob. 2,000 Jews there — from 25.10.1941 had to obey a decree issued by the Germ. Generalgouverneur (Eng. General Governor) of the GG, Hans Frank, according to which „Jews who leave their designated district without authorization are subject to the death penalty. The same punishment applies to persons who knowingly provide hiding places for such Jews”, and „Instigators and helpers are subject to the same punishment as the perpetrator; an attempted act will be punished as a completed act. In less serious cases, a prison sentence or imprisonment may be imposed”. After the start of the Germ. «Aktion Reinhardt», Lubaczów, c. 8 km away, became the local center of the genocidal program. In the spring of 1942, c. 2,270 Jews lived there, and additionally in 05.1942, c. 2,000 Jews from the surrounding areas were brought to this town. On 08.10.1942 the Germans announced the creation of a ghetto — initially open — and ordered all Jews to move there. Immediately afterwards, at the end of 10.1942, with the help of the Germ. Ukrainische Hilfspolizei, in the first Germ. Aktion (Eng. operation), the Germans deported — prob. by train, through Rawa Ruska — c. 2,000 Jews from Lubaczów to the Germ. Vernichtungslager (Eng. extermination camp) VL Belzec, c. 35 km to the north–east, established by the aforementioned génocidaire Globočnik on the site of the former AL Belzec camp, where they were all murdered. In their place, in 11.1942, Jews from Oleszyce were brought in, and immediately afterwards prob. c. 1,000 of them were transported out to their deaths in VL Belzec. This was to happen just before 01.12.1942, when the ghetto in Lubaczów was „closed” by surrounding it with a barbed wire fence. Even before the end of 1942, several hundred Gypsies, i.e. Roma, were brought to the ghetto to be driven outside the town, into the forest, and, over pits previously dug by the Jews, murdered along with those Jews. Meanwhile, an epidemic broke out in the ghetto — 25 people died a day — and already on 06‐08.01.1943, the Germans, together with Ukrainians of the Germ. Ukrainische Hilfspolizei, organized the second Germ. Aktion. Hundreds of elderly and sick Jews were murdered in the town center, the bodies buried in the Jewish cemetery. The remaining — c. 2,000 — were deported from the town on the same 08.01.1943. Their fate is unclear — according to some sources, they were transported c. 150 km north, to the Germ. Vernichtungslager VL Sobibor (VL Belzec was in the process of being closed); according to others, they were driven c. 5 km to the north, to the vicinity of the Hrynków farm and the village of Dachnów, which in the years 1939‐1941 had been located in the so‐called Russian border zone, where the Russians constructed the so‐called Molotov Line — a series of defensive forts and trenches, near Lubaczów referred to as the 6th Rawa–Russian Fortified Area. The Germans and Ukrainians were supposed to murder them in these trenches. The Germans were able to declared that Lubaczów was Germ. „Judenrein” (Eng. „free of Jews”).

At the same time, in 02.1943, several hundred kilometers to the north‐east, in Volyn, Roman Shukhevych, nom de guerre „Taras Chuprynka”, the chief commander of the Ukrainian, genocidal OUN/UPA organisation, who in 1941 was a member of the Ukrainian Germ. Sondergruppe Nachtigall (Eng. Special Group Nightingale) — a unit of the Germ. Wehrmacht (Eng. Armed Forces) that took part in the German attack on Russians in 1941, accused of participating in the Jewish pogrom in Lviv in 1941 — and later a member of the Germ. Schutzmannschaftsbataillon 201 (Eng. 201st Protection team Battalion) — responsible for the murder of Jews and civilians in the territory of Belarus — issued an order: „The extermination operation should be carried out according to the following principles: Polish villages are to be burned, and their populations massacred. Attacks on towns will take place in broad daylight, not at night. In mixed villages, the Polish population alone should be liquidated, and farmsteads should be burned only if they are 15 meters away and when there is no risk of the fire spreading to neighboring Ukrainian buildings. The Ukrainian population will receive instructions as to where to gather during the attack […] For every Ukrainian murdered, whether by Poles or Germans, 100 (one hundred) Poles will be executed”.

It was the de facto signal for the commencement of the «Genocidium Atrox» — i.e. the genocide perpetrated by Ukrainians, known as „Volyn genocide”.

Immediately thereafter, in 03.1943, the UPA issued an appeal to members of the Germ. Ukrainische Hilfspolizei — who, in view of the end in many places of the Germ. «Aktion Reinhardt», i.e. the genocide of Jews, were becoming „unemployed” — to desert and join the UPA ranks. Perhaps as many as 10,000 Ukrainians did so.

Volyn was drenched in Polish blood. Tens of thousands of Poles were murdered by the Ukrainians — with German passivity — in an extremely barbaric manner. Hundreds of villages were burned.

And it is from this same period that the memories recorded in Polish sources come from, according to which was supposed to have „spread hatred towards Poles” in Oleszyce.

„During a sermon in March 1943 […] he shouted from the pulpit on a winter Sunday Ukr. "Lude beryte serpy i kosy, bo chas znyw ide" (Eng. "People, take up sickles and scythes, because harvest time is coming")”.

Taught that speaking Polish was a mortal sin.

Called for the collection of Catholic church birth and marriage acts and conversion to the Greek Catholic faith.

At one of the village meetings, is also said to have stated that „the time has come for the Poles to be treated the same way as the Jews”.

Although Shukhevych's order was not formally addressed to the units of the Germ. Ukrainische Hilfspolizei in the Germ. Distrikt Galizien — because there, in 1943, the genocidal OUN did not establish an armed wing under the name UPA, but formed armed units under a euphemistic name, to „confuse” the Germans, of Ukr. Українська Народна Самооборона (Eng. Ukrainian National Self‐Defense), i.e. UNS, whose main goal, like the OUN/UPA, was the extermination of the Polish population, although its internal documentation and reports ostentatiously stated „defense against the terror of the German authorities” — but de facto there, too, Ukrainian génocidaires, „unemployed” after the end of the Germ. «Aktion Reinhardt», deserted. And joined the UNS.

And in 12.1943 — when it became clear that the Germans were losing the war in the East, i.a. on 24.12.1943, a major Russian offensive called the Dnieper–Carpathian Operation began — the UNS was formally transformed into a unit of the genocidal OUN/UPA, i.e. „UPA‐West”. In 01.1944, its commander became another of the Ukrainian „trainees” of the Germ. Sondergruppe Nachtigall and the Germ. Schutzmannschaftsbataillon 201, the degenerate Vasyl Sydor, nom de guerre „Shelest”, who almost immediately ordered „to strike relentlessly at the Poles until they are completely destroyed from these lands”. He could have done safe with the knowledge that the UNS/UPA had nothing else to do at the time, because — as even Ukrainian Wikipedia confirms — „during the last months of 1943, UNS units did not conduct armed operations due to the introduction on 02.10.1943, by the Germans in Galicia of the system [of collective responsibility] of executing 10 hostages for the murder of every German soldier or official”. The Poles did not participate in the structures of this occupation power.

The «Genocidium Atrox» began in the Germ. Distrikt Galizien. The Germans were passive in the face of the UNS/UPA's genocidal acts, generally not undertaking any major operations against Ukrainians.

In the Lubaczów area, from c. 04.

1944, the «Genocidium Atrox» was carried out by the Chief of Staff of the OUN/UPA Military District WO‐2 „Bug” of the „UPA‐West”, Miroslav Onyshkevych, nom de guerre „Orest”. On 06.04.1944, this genocidal leader specified the tasks of the UPA units under his command as follows: „I order the immediate purging of my region of the Polish element […] The purging should be carried out in the sparsely populated areas by Poles. For this purpose, a militia group composed of our members should be established in the area, whose task would be to eliminate the above‐mentioned. Larger areas will be purged of this element by our military units even in broad daylight […] Fight them hard and ruthlessly. Spare no one, even in the case of mixed marriages. Pull the Poles out of their homes, but do not eliminate the Ukrainians and children in these houses […] Take out your weapons. Death to the Poles”.

The attacks on Poles began. E.g. in the neighboring village of Stare Sioło, in 01‐07.1944, Ukrainians murdered c. 20 Poles.

On c. 22.07.1944, during the offensive known as the Lviv–Sandomierz Operation, the Russians entered his village of Oleszyce. The Russian occupation began. However, the Russian offensive was halted in 08.1944 — on the orders of the highest Russian authorities. The cause was the outbreak of the Warsaw Uprising on 01.08.1944, i.e. the Polish Clandestine State, the largest resistance movement in the occupied Europe, attempted to take over power on Polish territory before the Russians entered. The Russians, de facto in a momentary strategic collusion with the Germans, allowed the Germans to crush the Uprising and murder c. 200,000 Poles. This meant that Oleszyce and the surrounding area, until 01.1945, became a front‐line area, a place of quartering for thousands of Russian soldiers. The power of the Russian front troops was so overwhelming that on 01.09.1944, Vasyl Sydor, nom de guerre „Shelest”, ordered a halt to the action against the Polish civilian population, but the order did not include „the Polish element collaborating with the NKVD and the organs of Moscow imperialism”. The OUN/UPA was still to attack „a Polish militia of 20 people in some locality. One third or half of them should be destroyed, the rest disarmed and warned that if they do not stop collaborating with the Bolsheviks against us, they will also be destroyed next time”.

And then, in 12.1944, from Oleszyce — the population of this town dropped to c. 1,500 — was moved c. 25 km to the east, to Horyniec, inhabited by c. 1,900 people, of whom Roman Catholic Poles constituted c. 68% and Greek Catholic Ukrainians c. 31%. Took also over the ministry in the neighboring village of Radruż, where an estimated 2,500 people lived, of whom in 1939 Greek Catholics constituted 90% of the inhabitants. At the end of 1944 it was prob. already a purely Ukrainian village, because earlier, on 23.04.1944, on Low Sunday, also known as Easter of the Dead, at the end of the German occupation, the genocidal OUN/UPA murdered c. 14 Poles there: „The UPA set fire to houses and simultaneously began looting. They stole food and valuable items, at the same time mocking each and calling Poles various perfidious names. In the distance, one could hear screams, cries, the roar of animals, and continuous gunfire. Many Ukrainians from Radruż rejoiced at the sight. Then they completed the robbery, taking everything they could, even beehives”.

On 12.01.1945, the Russians launched a decisive offensive in the east, the so‐called Vistula–Oder Operation. They were secured in the rear, because the Polish ClandestineState and the Home Army AK, due to the bloody suppression of the Warsaw Uprising by the Germans, were very weakened, so it was possible to leave the occupied territories under the control of the genocidal NKVD and Polish traitors collaborating with it, i.e. the so‐called Russian Polish Republic, i.e. prl. At the same time, the Polish government operating in London and the Polish Clandestine State decided to disband the AK. This happened on 09.01.1945.

And then, in the lands that the Russian front troops had left, the genocidal OUN/UPA began to become active. This particularly concerned the area between the so‐called Curzon–Namier line and the San river, i.e. between the Bug and San rivers, referred to by Ukrainians as Zakerzonia, which the OUN/UPA considered to be the western part of the future Ukrainian state. The Curzon–Namier Line was a demarcation line between Poland and the Russian Bolsheviks, proposed on 11.07.1920, to the Russians by the British Foreign Secretary, George Curzon, during the Russian offensive during the Polish–Russian War of 1919‐1921, suggested by the so‐called expert, Lewis Bernstein Namier, a Jew of Polish origin. Russia — contrary to the plans of the British imperialists — suffered defeat in 1920, but the concept of the Curzon–Namier line, running through the center of Poland, became a cause célèbre for all imperial concepts of the division of Central Europe, especially the Russian and German ones. It was then, at the beginning of 1945, that the above–mentioned génocidaire Miroslav Onyshkevych, nom de guerre „Orest”, became the commander of the OUN/UPA Military District WO‐6 „San”, which included Zakerzonia.

The complicated situation was compounded by the decisions made on 28.11‐01.12.1943, by the main leaders of the anti‐German coalition‐the USA, Great Britain, and Russia‐at the Tehran Conference. At that time, it was de facto agreed that pre‐war Poland would be divided, and the areas seized and occupied by Russia in 1939 would become part of Russia. In this way, the coalition partners validated the genocidal Molotov–Ribbentrop Pact, in its part concerning Russia. One of the changes decided upon by the Russian leader, the génocidaire Stalin, was to leave the areas west of the Bug River, e.g. Zakerzonia, within the borders of the Polish Russian Republic, i.e. prl. However, the Russians did not intend to stop at simply drawing new borders‐they also intended to solve national and social problems using the old, tried‐and‐true Russian method. This involved the deportation of entire nations and societies.

Over a million Poles from the so‐called Pl. Kresy (Eng. Borderlands), i.e. the territories east of the Curzon–Namier line and the Bug River, began to be forced to emigrate westward and northward to the „prl”, to lands that in 1939 were part of Germany. And Ukrainians and Rusyns, mainly from Zakerzonia, began to be forced to emigrate eastward, to areas that were to belong directly to communist Russia. The first phase of deportations of Ukrainians from prl, lasting until the end of 1944, was „voluntary”. C. 20,000 people left for Russia. The second phase began on 01.01.1945, and was generally met with resistance. There were few who volunteered.

At the same time, at the beginning of 1945, after the Russian front troops had left, there was a clash between the three main forces operating in this area. On the one hand, Ukrainian genocidal forces from the OUN/UPA, fighting for Ukrainian Zakerzonia, carried out murders and pacifications of Polish villages, as well as attacks on Russian forces, including the genocidal NKVD, supported by Polish units that had decided to betray the ideals of an independent Poland and began collaborating with the Russians. On the other hand, the heirs of the Polish Clandestine State, who after many years of fighting against the Germans, intending to return to civilian life, were accused by the Russians and their Polish collaborators of … collaboration with the Germans, and in practice forced to renew the resistance and partisan movement. At the same time, they had to defend villages attacked by genocidal forces from the OUN/UPA. Today, the term used to describe them is „cursed soldiers”. The third side were the Russians, particularly the genocidal NKVD units, supported by the growing in strength‐backed by Russian power‐Commie‐Nazi units of the prl. They fought the OUN/UPA, but mainly Polish patriots, former members of the Polish Clandestine State, seeing it as the greatest threat to Russian rule.

His new parishes — both Horyniec and Radruż — were located right on the new border, which was supposed to separate the prl from the territories directly occupied by the Russians, on the side of the Commie‐Nazi prl. Ukrainian residents were encouraged to „voluntarily” emigrate east.

According to some sources, consented and was preparing to move east.

And it was then that was murdered.

The murder took place in the house where he resided.

His daughter recounted that „the murderers burst into the room screaming, pushed my father out the door, and shot him dead with a burst from a machine gun on the doorstep”.

Another source states that „in December, a priest [Petro Wolanowycz] from the monks came to us [in Radruż], he served our village and Horyniec. He lived in Horyniec because he was afraid to live in our village […] He lived there only three months because in February 1945, the Polish militia came and shot him in bed”.

Still another that „in Horyniec, they shot Father Petro Wolanowycz when, on their orders, he was serving them dinner and turned to the cupboard for vodka was hit in the back of the head”.

The perpetrator of the murder was prob. a member of the criminal Security Service UB, the Polish unit of the Russian NKVD, from Oleszyce — according to some sources, there were two of them — where had previously ministered. One source specifies that the perpetrator was a member of the UB from Lubaczów.

On 12.10.2007, the génocidaire Roman Shukhevych was posthumously awarded the title of Hero of Ukraine. On 10.12.2017, on behalf of the „Coordination Council for the Commemoration of Decorated Knights of the OUN and UPA”, génocidaire Vasyl Sydor was posthumously awarded in Lviv the Silver Cross of Military Merit of the UPA, 1st Class (No. 009). In several locations, monuments and commemorative plaques have been erected to these Lat. „hostis humani generis”, the schools were named after them.

Lat. „O Tempora! O mores!”
