In the Crosswind is a drama about this, a mass deportation by the Soviet Union in 1940-1941?
June deportation The June deportation (Estonian: "Juuniküüditamine" , Latvian: "Jūnija deportācijas" , Lithuanian: "Birželio trėmimai" ) was a mass deportation by the Soviet Union of tens of thousands of people from the territories occupied in 1940–1941: Baltic states, occupied Poland (mostly present-day western Belarus and western Ukraine), and Moldavia.
Rudolf Vrba Rudolf "Rudi" Vrba (11 September 1924 – 27 March 2006) was a Slovak-Jewish biochemist who, as a teenger in 1942, was deported to the Auschwitz concentration camp in German-occupied Poland. He became known for having escaped from the camp in April 1944, at the height of the Holocaust, and for co-writing a detailed report about the mass murder that was taking place there. Distribution of the report is credited with having halted the mass deportation of Hungary's Jews to Auschwitz in July 1944, saving over 200,000 lives. After the war Vrba became a noted biochemist in England and Canada.
