Drei Kreuzen

These 3 crosses are very close to the Gaimersheim-Eichstätt road, so I have been passing them occasionally for 3.5 years.

I also pass them from time to time when I cycle in that direction, as I did to day.

I found that the local "veterans association" has erected a sign explaining what they are. A mystery solved?

Well, it would be if my German was up to translating the sign. I think they date back to 1813.

Where's my dictionary?
