 His plight became an international cause célèbre, with Hasidim and non-Hasidim throughout Eastern Europe petitioning government officials and even priests to save the Rebbe from extradition and exile.Moving from town to town — including Shatsk in Bukovina (which belonged to Austria), Kompling, and Skola — the Rebbe ended up in Sadigura, Bukovina, home to the second-largest Jewish community in Austria (after Chernowitz).In that town, 40 years before, a 10-year-old boy named Yisroel Donenfeld had disappeared without a trace.
