I am researching my grandfather who was a Podporucznik in the Polish army in the USSR and fought with them during WWII. I have had trouble figuring out his military past and I'm wondering if anybody here has any idea on how to research a soldier from that army. Files, Records, Medals, Etc, Anything that would help.
If you do find something that would help me in researching my grandfather then I will be really thankful and glad. :)
