The Battle of Verdun lasted for 300 days with over 1 million French soldiers serving in the sector, and the French artillery firing at estimated 23 million rounds. To keep the frontline supplied with men and materiel was a major logistical effort during the course of the battle.
It was along a 56 kilometre route route from Bar-Le-Duc to Verdun and a narrow gauge railway on which the logistics to sustain the battle depended. It became known as the Sacred Way ... La Voie Sacrée.
Along the route 6,000 lorries and buses passed every day, one vehicle passing every 14 seconds, day and night.
