French war planning 1920–1940

The Dyle Plan or D Plan was the plan of the Commander-in-Chief of the French Army Général d'armée Maurice Gamelin to defeat a German invasion of France through Belgium. The Dyle (Dijle) river is an 86 km (53 mi)-long river from Houtain-le-Val through Flemish Brabant and Antwerp and the objective was to halt the German army along the line of the river. The Franco-Belgian Accord of 1920 co-ordinated communication and fortification efforts of both armies. After the German Remilitarization of the Rhineland on 7 March 1936, the German Army (Heer) closed up to the Belgian border and the Belgian government adopted a policy of strict neutrality.
