ARGONNE, a rocky forest-clad plateau in the north-east of France, extending along the borders of Lorraine and Champagne, and forming part of the departments of Ardennes, Meuse and Marne.
The Argonne stretches from S.S.E.
There are many forests which clothe the slopes of the plateau.
The other principal river, the Aisne, crosses the southern border and takes a northerly, then a westerly course, separating the region known as Champagne Pouilleuse from the more elevated plateau of Argonne which forms the central zone of the department and stretches to the left bank of the Meuse.
Dumouriez succeeded in rousing the spirit of the French; he occupied the defiles of the forest of Argonne, thus causing the enemy to lose many valuable days, and when at last they turned his position, he retreated without loss.
Cones of Lower Cretaceous age have been described by Fliche from Argonne, which bear a close resemblance to the female flowers of recent species of Cedrus.
Agriculture is carried on to most advantage in the Champagne and Argonne.
