First World War Trench Map RICHEBOURG showing The Distillery, a photo by theakston-thomas on Flickr.
Via Flickr:This image, one of several of this area, shows the trenches around The Distillery at Richebourg.
The red lines are the trenches and fortifications of the German Army. The blue lines are those of drainage ditches. The British and Allies were just to the west (left) of the German lines. It is interesting to net the heavily fortified system in Red Xs protecting the Distillery.
