First Battle of the Marne (the Miracle of the Marne)

The Battle of the Marne (French: 1re Bataille de la Marne) (also known as the Miracle of the Marne) was a First World War 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 the war 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.
