In doing so he exposed his right flank to counterattack by the French and a British Expeditionary Force, resulting in the First Battle of the Marne, September 6—10, Despite casualties in the hundreds of thousands, the battle was a stalemate, but it stopped the German drive on Paris.
Both sides began digging a network of trenches. The First Battle of the Marne was a window onto how the rest of the war would be fought: The centuries-old method of massed charges to break through enemy positions did not work when the men faced machine guns, barbed wire, and drastically more effective artillery than in the past.
