if someone from Silesia ended up in a gulag before September 1939
actually - someone from Silesia could not live in western SU in 1939 - I meant if any Polish person ended up in a gulag it was either Polish communist (Stalin targeted KPP - all who lived in the Soviet Union were arrested - only a handful survived) or a Polish citizen of the Soviet Union (of the said Polish minority in western SU amounting possibly to 500 000)
