While we are playing with Googe Earth

Coulmiers  was notable as a true French victory.  The landscape is about as flat as it gets.  Here's a kilometer line roughly north-west from the German position at Coulmiers.  I chose this so that I would have some hope of orienting on the road.

 

Here's a view down the road.  You can see the forest, but the road disappears after only a few hundred meters.

Now, this image is from down the main highway, labeled "Alternate view from here" if you enlarge the image with the line.

You can't really make out the road, but what is interesting is the degree of dead ground.
