In memory of the many French troops who valiantly fought in the woods and ridges around Stonne, a ‘circuit de memoire’ has been set up which you can drive around. There are fourteen different stops covering different aspects of the hard fought battles of Stonne. A small museum in Stonne is the starting point. Some of the roads can be a bit rough though a normal car can probably catch most of the stops if the weather has not been too wet.
A series of memorials can be found southwest of Stonne towards Tannay and near the ruins of the monastery of Mont Dieu where the German breakthrough was finally solidified. Some 3,000 Germans died in the fighting around here as opposed to 1,000 French.
The main French defense line was pierced at Sedan by German attacks on 13-14 May 1940. With the bulk of the Allied army positioned to the north and west of Sedan, it was imperative that the French seal off the German breakthrough - as important also to the Germans to solidify their gains. A series of hard fought battles were fought in the forests and ridgelines around the Butte de Stonne from 14 May to 24 May in which the little village would change hands some nineteen times. The Butte de Stonne is just east of the small village sitting on a horseshoe turn of road D 30. Walking up past a more recent vintage French tank - a LeClerc - you come up to a grand viewpoint with long ranging views up and down the Meuse and south into the Argonne.
