History / Is there a list of those in the Polish Army during WWII? [193]

good afternoon ! I am looking for information about my grandfather, who was Polish born in Warsaw and fought in WWII, his name was Janusz Nowakowski Nikolayedsky. I was born in 1927, I think. He has several medals, but we know very little because he died in 1957 in Venezuela, my mother almost did not know him. Can you please help me get information ??
