A hundred years ago from the 5th September to the 12th September 1914, the first battle of the Marne happened between Germany and Franco-British troops.
On the 29th of August, the allied powers are unable to stop the German advance on the western front. Some parts of France are already under complete German occupation. Paris, a German target, felt threatened by this advance and the French government made the decision to leave Paris and settle in the city of Bordeaux, in the South.
On the 26th of August, the allied troops are retreating in front of the German advance.
A hundred years ago, France knew the bloodiest day of its history. Never before or after this day has France lost so many soldiers.
