Commemorating the Battle of Marne fought between September 6 – 9, 1914 during the First World War. The engagement marked the end of the so-called Great Retreat of the British Expeditionary Force (BEF) and the French Army which had been taken unawares by the German forces. Halting the German advance the allied troops were able to claim their first decisive victory in the war. The Germans were forced to retreat 56 miles losing 15,000 men who were captured, 30 field-guns and 100 machine-guns before reaching the Aisne. This success effectively ended German hopes of a quick victory on the Continent.
