I want to know the answer to the following question:
When were the deported Estonians allowed to return?
All the background I'm provided with is that "The activities of Soviet forces in 1940–41 and after reoccupation sparked a guerrilla war against Soviet authorities in Estonia by the Forest Brothers, who consisted mostly of Estonian veterans of the German and Finnish armies and some civilians.". Is that enough to answer the question?
Answer: no
