I just ran across an interesting article posted (English) on Mukachevo's Greek Cathoic Eparchy website about Father Petro Oros. He served underground in the Irshava and Vinogradovo districts. The following is an excerpt:
On August 27, 1953 in the village Velyki Komyaty, on the eve of the feast of the Dormition of the Mother of God, he celebrated solemn Holy Liturgy, heard confessions and distributed Holy Communion. The next day he went on foot to the train station in Siljce. Father Petro was arrested there by the militia. They took him in the direction of the village Zaricchya. Near the road Crucifix two shots were fired – Father Petro was killed. His body was taken to the morgue of the Irshava hospital and after few days he was secretly buried near the village of Kamyansjke of the Irshava district. Later, his remains were exhumed by the militia and KGB and taken in to Irshava.
