Polish POW transfer from Russians to Germans 1939

old family records state my dad was captured by Russians in 1939, held for a while in Lagiers then there was a prisoner exchange in Hannover, Germany in 1939 or 1940 and dad went to Stalag XXA , the first of many Stalags . I can find no information online about this prisoner exchange. It must have been a big deal involving many POWs. Does anyone have information on this exchange?

Thanks Roman

WWII Exchange of Polish POW's 1939-1940

Family history says my dad was in a prisoner (POW) exchange, Captured by the Russians in late 1939 and in Lagiers then transferred/exchanged to the German and then in Stalags starting with XXA in Thorne. This POW exchange happened in or near Hannover, Germany in 1939 or 1940. I am not seeing the exchange by simple internet search. Anyone have more information, it must have been significant?

Thanks
