10th February marks the start of the 1st wave of deportation of Polish citizens by the Soviets.
My mother and her parents were actually deported in the 2nd wave of deportations on 13th April and were sent to Kazakhstan.
She never really spoke of the deportations. She mentioned it now and again but never gave any details.
Maybe the book on this website may shed some light on what they might have gone through.
