In France, the Chemin des Dames (literally, the "ladies' path") is part of the D18 and runs east and west in the département of Aisne, between in the west, the Route Nationale 2, (Laon to Soissons) and in the east, the D1044 at Corbeny. It is some thirty kilometres long and runs along a ridge between the valleys of the rivers Aisne and Ailette. It acquired the name in the 18th century, as it was the route taken by the two daughters of Louis XV, Adélaïde and Victoire, who were known as Ladies of France. At the time, it was scarcely a carriage road, but it was the most direct route between Paris and the Château de Boves, near Vauclair, on the far side of the Ailette. The château belonged to Françoise de Châlus, former mistress of Louis XV, Countess of Narbonne-Lara and former lady of honour to Adélaïde, whom the two ladies visited frequently. To make the way easier, the count had the road surfaced, and it gained its new name. The ridge's strategic importance first became evident in 1814 when Napoleon's young recruits beat an army of Prussians and Russians at the Battle of Craonne.
Three battles were fought along the Chemin des Dames east-to-west ridge located to the north of Paris during the First World War. All are named after the river which flows on the south side of the ridge. Their names are as follows:
During World War I, the Chemin Des Dames lay in that sector of the Western Front held by the French Army. Its strategic importance made it the staging ground of several major battles that took place between 1914 and 1918. The German army took a defensive stand on the ridge in September 1914, stopping the advancing Allied armies after the Battle of the Marne. After intensive combat, Germans took control of the plateau in November 1914.
