In short
In early September 1914, the German army's rapid advance toward Paris stalled along the Marne River, where French and British forces launched a counteroffensive that halted the invasion. The battle lasted a week and cost over 250,000 casualties on each side, but it shattered Germany's plan to win the war in weeks and locked both sides into a grinding stalemate that would define the next four years.
How it unfolded.
The five-minute version
What actually happened.
The First Battle of the Marne or known in France as the Miracle on the Marne was a battle of the First World War fought from 5 to 12 September 1914. The German army invaded France with a plan for winning the war in 40 days by occupying Paris and destroying the French and British armies. The Germans had initial successes in August. They were victorious in the Battles of Mons and the Frontiers and overran a large area of northern France and Belgium. In what is called the Great Retreat the Germans pursued the retreating French and British forces more than 250 km (160 mi) southwards. The French and British halted their retreat in the Marne River valley, while the Germans advanced to 40 km from Paris.
