Following the end of second World War, 48 percent area of the Second Polish Republic was incorporated into the Union of Soviet Socialist Republic. A significant number of Polish citizens remained in the annexed areas and along with them their pastors. As for members of the Society of St. Francis de Sales (Salesians), ten remained in the areas incorporated into the USSR, who helped organize the religious life of the faithful under very difficult circumstances. They maintained contact with the religious congregation in Poland, mostly it was limited to correspondence and short visits on the occasion of family visits to Poland. The source presents notes from the stay in the USSR of Fr. Stanisław Rokita SDB, who in 1973 was the first Salesian superior to visit his congregation remaining in the East.
