THE FRONTIER IN 1914 AND DEFENCES OF THE MEUSE
In constructing these defences, Gen. Séré de Rivières’ plans provided for the concentration of the French Armies to the west of the Meuse, the bridges being within range of the guns of the forts on the Meuse Heights. The quadrilateral formed by Woëvre Plain was open to the enemy.

The Frontier in 1914
(See map, [p. 8.])
If we look at a map of the Franco-German frontier of 1914, between Nancy and Verdun, it will be seen that two rivers—the Meuse and the Moselle—ran parallel with the frontier, forming a double line of defences. The Moselle is protected by the hills of that name, and the Meuse by the Heights of Meuse, the eastern side of which, facing Germany, consists of a series of steep cliffs.
When, in 1875, General Séré de Rivières was instructed to fortify this frontier, his plans provided for the construction of a line of forts along the Meuse Heights, capable of holding the bridges across the Meuse under gunfire, and thus enable the French Armies to concentrate behind the river near Neufchâteau. The three northern forts, therefore, faced the Meuse; the southern forts, viz., Gironville and Liouville, commanded both the Meuse and the Woëvre.
The drawback to this plan was that the vast Woëvre Plain lying between Stenay, Longwy, Toul and Nancy, would be sacrificed in the event of a surprise attack. The importance of this possible loss was made all the greater by the discovery of coalfields in the Briey district. It was therefore decided that a number of battalions of Chasseurs should be garrisoned in the Woëvre towns. Moreover, the passing of the Three Years’ Military Service Bill made it possible to increase considerably the number of covering troops. In 1914, the Plan of Concentration provided for the grouping of the French Third Army in the Woëvre Plain. However, no permanent defences were erected. The fortress of Longwy, being isolated and of little military value, could not give effective protection.
