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.
Greek Operation of the NKVD The Greek Operation (Russian: Греческая Операция , translit. Grecheskaya Operatsiya; Ukrainian: Грецька операція ) was an organised mass persecution of the 450,000 Greeks of the Soviet Union that was ordered by Joseph Stalin. Greeks often use the term "pogrom" (πογκρόμ) for this persecution, though this term usually refers to mob violence rather than persecution by police acting under direct orders, as this one was. It began on December 15, 1937 and marked the beginning of the repressions against Greeks went on for 13 years.
