If you know your PESEL number the cops can verify you’re a Polish citizen by calling the Polish Embassy/Consulate in Germany. Good Luck!
Wow. Interesting question, and one we don’t get here very often.
My suggestion would be to ask your unit staff. They should probably be told that you’re going to Poland, so you can ask the documents question as well.
