This post about the battlefield of Vauquois is the second part of two posts on aerial stereo photography during the First World War. For a brief introduction to aerial photography during the conflict I suggest to read this post first.
The German army captured La Butte de Vauquois on 24 September 1914 and the strategically important hill was turned into a fortress by the Germans, protected by their artillery in the woods behind it. Until March 1915, there was a battle to recapture the hill and the French recaptured the southern half of the now devastated village of Vauquois.
From that moment a static warfare started. Both armies dug in and the battle moved underground. Tunnels were dug under enemy lines on both sides and large quantities of explosives were placed and detonated. The hill of Vauquois became a huge ant's nest with underground rooms, shafts and corridors. The American army finally recaptured the hill on 26 September 1918.

The stereoviews have a size of 9 x 18cm and show the mine craters and trenches of the battlefield. The images of the destroyed landscape look like a lunar landscape. The descriptions on the slides show various valuable information, such as: location, compass direction, altitude and the date of 4 March 1917. One slide has a label with F44. It refers to Escadrille 44, the squadron of the French Airforce that took the stereo photos.

This is how the Vauquois battlefield looks today. The mine craters on the stereoviews are still visible today:
