This battery lies along the D 170. Be aware, there are many villages in the region named "Kernours". It is Lo 337 and the battery was called "Pilsen". It was confusing to find only one Fl 243a. In the beginning of 1944 the occupation changed from 9./MFlA 704 to 4./MFlA 807.
An empty birdsnest brings you back to the present.
