When Did The Battle Of Marne Take Place?

The First Battle of the Marne (also known as the Miracle of the Marne) was a World War I battle fought between the 5th and 12th of September 1914. It resulted in a Franco-British victory against the German Army under Chief of Staff Helmuth von Moltke the Younger. The battle effectively ended the month-long German offensive that opened World War I and had reached the outskirts of Paris. The counter-attack of Allied forces during the First Battle of the Marne ensured that a quick German victory was impossible, and set the stage for four years of trench warfare on the Western Front.

The Second Battle of the Marne, or Battle of Reims (15 July to 6 August 1918) was the last major German offensive on the Western Front. It failed when an Allied counterattack led by French forces overwhelmed the Germans, inflicting severe casualties.
Following the failures of the Spring Offensive to end the war, Erich Ludendorff, Chief Quartermaster-General and virtual military ruler of Germany, believed that an attack through Flanders would give Germany a decisive victory over the British Expeditionary Force (BEF), the most potent Allied force on the Western Front at that time. To shield his intentions and draw Allied troops away from Belgium, Ludendorff planned for a large diversionary attack along the Marne.
