A group of people living in the countryside applied to join the Swiss war effort to help defend the major town. They became known as The District Protection League. It was dispanded some years after the war. It is a commemorative medal and the only one I could find was sold for $22. Hope this helps a bit.
I was able to find another medal on Numista searching PEKA. It says that was the engraver. It was also a swiss medal.
As I mentioned above, this is your medal but there is little info online about them. https://www.ricardo.ch/de/a/medaille-appenzeller-bezirksschuetzenverband-hinterland-1236115954/
