Searching for lost ancestors / information

Hi I was wondering in anyone understands this handwriting and could possibly decipher it. I think i could translate it if i had it in front of me non handwritten but any translation help would be amazing.

It is a certificate from ancestors from Poznan as my gran escaped out of Germany, she was captured at 15 years old and held captive to work on a farm.

She lost contact with her parents and siblings.

I don't get why they would use so many curly letters. Being Polish I understand only a couple of words, like "Z wojska na Piekary 15"? on the last image.

most of those words are in German from what I can gather

Hello,
Does anyone know who I should contact to try to find a birth certificate or baptism record for my grandmother born in West Prussia in 1870?

West Prussia in 1870 was a part of Germany, but it included a lot of today's Polish territory. I'd try to inquire in a Gdansk matrimony office, maybe they can point you out to the right direction.
