Latvians in railcars in the process of deportation in 1941
June deportation (Estonian: Juuniküüditamine, Latvian: Jūnija deportācijas, Lithuanian: Birželio trėmimai) was the first in the series of mass Soviet deportations of tens of thousands of people from the Baltic states, Belarus, Ukraine and Moldova starting June 14, 1941 that followed the occupation and annexation of the Baltic states. The procedure for deporting the "anti-Soviet elements" was approved by Ivan Serov in the so-called Serov Instructions. Men were generally imprisoned and most of them died in Siberian prison camps (see Gulag); women and children were resettled in Kirov, Tomsk, Omsk and Novosibirsk Oblast as well as Krasnoyarsk and Altai Krai. About a half of them eventually survived.
After the war, further deportations, known as Operation Priboi, were staged in a much larger scale.
