Bogatyrets was one of those who seized this opportunity, leaving with Stefanida and his two children (Nicolae and Nadezhda). They would spend some six months at Leubus Monastery, Gau Silesia, where Father Kassian treated his illness and did research in the library. He was registered as a refugee in the Leubus camp for prisoners-of-war, and visited there by the Romanian Commission. Eventually, the Commission obtained that he and his family be returned to Romania, where Bogatyrets served as a parish priest in Monteoru. In July 1941, the German–led attack on the Soviet Union brought the Romanian administration back into northern Bukovina. After protracted negotiations, the Bogatyretses were also allowed to return to Bukovina in September, settling in Cernăuți. Tit Simedrea, the new head of Bukovina Diocese, made Father Cassian his confessor, assigned to "Intrarea în biserică" ("Svyato Vvedensky") Monastery.
