During and after World War II, the Soviet Union deported roughly 10% of the population of the Baltic states, making it difficult for guerrillas to obtain food and supplies from the population.
Notes on verification
Multiple independent sources confirm large-scale Soviet deportations/killings/imprisonment of Baltic populations and their strategic aim to cut off support for partisan resistance. However, the precise '10% deported' figure appears to conflate combined categories (killed, imprisoned, deported) rather than deportation alone, introducing some imprecision.
