Plan XVII (pronounced[plɑ̃dis.sɛt]) was the name of a "scheme of mobilization and concentration" that was adopted by the French Conseil Supérieur de la Guerre (the peacetime title of the French Grand Quartier Général) from 1912 to 1914, to be put into effect by the French Army in a war between France and Germany. It was a plan for the mobilisation, concentration and deployment of the French armies, to make possible an invasion of either Germany or Belgium or both, before Germany completed the mobilisation of its reserves simultaneous with a Russian offensive.[1]
The plan was implemented from 7 August 1914, with disastrous consequences for the French, who were defeated in the Battle of the Frontiers (7 August – 13 September) at a cost of 329,000 casualties. The French armies (and the British Expeditionary Force) in Belgium and northern France were forced into a retreat as far as the Marne river, where at the First Battle of the Marne (5–12 September), the German armies were defeated and forced to retreat to the Aisne river, eventually leading to the Race to the Sea.
