Dominating the entire Argonne eastern region, Vauquois was considered by the staff headquarters on both sides as an exceptional observation point and a strategic barrier.

On 24th september 1914, the Germans occupied this hill and made it into a genuine fortress.
On 4th March 1915, after several offensives, the French took hold on the hill. The war of position was about to start.
The soldiers went underground and dug out miles of galleries ans ramifications in order to infiltrate the enemy's network and to cause a maximum amount of loss using tons of explosives.
Vauquois hill thus became a real anthill composed of several underground installations spread over several levels (more than 17 kms of shafts, galleries and ramifications).

One of the most significant places of mine warfare (an inventory was made indicating 519 explosives : 199 German and 320 French), Vauquois was freed on 26th September 1918 by the Americans. Still intact from the Great War, Vauquois hill has been listed as a Historic Monument.
